If you've ever been told lifestyle change is the key to losing weight, this episode might make you rethink the job we've been asking lifestyle to do. Now that powerful medications can produce substantial weight loss, what is healthy eating and movement really for?

Join Holly and Jim as they sit down with Dr. Gary Foster, a clinical psychologist who has spent decades studying behavioral weight management. He has led academic research programs, served as chief science officer at WW (formerly Weight Watchers), and is now chief scientific officer and head of clinical and medical affairs at Lingo, a division of Abbott. Gary has seen lifestyle treatment from every angle, and he makes the case for reinventing it, not abandoning it. You'll hear what behavioral science got right, what it got wrong, and why lifestyle may matter more than ever, even when the scale isn't the point.

Whether you're on a GLP-1 or just curious about where weight management is heading, you'll gain practical ideas and a more hopeful outlook. It's not medications or lifestyle. It's medications and lifestyle.

Discussed on the episode:

• The question that may change how you think about lifestyle programs: have we been asking them to do the wrong job?
• What decades of behavioral science got right, and the surprising things it missed
• Why Gary says "some is better than none" when it comes to tracking, and a realistic way to build awareness without logging everything
• The "I wonder…" mindset shift that makes healthy habits feel lighter.
• The two signals, beyond the number on the scale, that Gary suggests paying attention to
• Why eating less and eating better are not the same thing, and what people on these medications are asking for help with
• A simple behavior that may be easy to overlook when your appetite and thirst cues change
• The one habit Gary says predicts who keeps weight off, and why no pill or injection can teach it.
• Gary's advice if you haven't exercised in years (hint: it starts smaller than you think)
• What we really know, and don't yet know, about life after stopping a medication.
• Why planning for "what happens when I reach my goal" is worth doing now
• Where obesity rates and prevention may be headed
• Rapid-fire questions, including Gary's most overrated piece of weight loss advice and the one thing GLP-1s changed his mind about
• The two habits Gary thinks everyone should prioritize, regardless of weight

What if the medications that were supposed to fix obesity turned out to be just the beginning of the story? After decades of studying weight loss, Holly and Jim thought they had seen it all. Then a new class of medications arrived and overturned some of their most basic assumptions.

In this episode, each of them brings five things that genuinely surprised them about the GLP-1 era. Some are about the science, some are about what they see in patients, and some are about what these medications were expected to solve but haven't. Two longtime experts admit what they got wrong, what they're still puzzling over, and where they disagree. Join Holly and Jim for a candid look at where obesity treatment stands now, and why they believe the most interesting questions are only just being asked.

Discussed on the episode:

• The question Holly and Jim never imagined asking in their careers, and why the answer may change what "success" means
• Why a tool once thought impossible outside the operating room is now in the hands of many
• The appetite finding that went against everything they'd taught about the body's backup systems
• What the medications haven't changed (so far), and why that disappointed one of them more than it surprised them
• A hormone-based therapy with a risk profile that Holly says doesn't behave the way hormones usually do
• The hidden "background noise" that patients only noticed once it was gone, and the swing Holly predicts is coming next
• Why so many people walk away from a treatment that works, and the two-track approach Jim and Holly take to that
• One medication, a surprisingly long list of possible uses, and a few that may raise your eyebrows
• Why Jim believes weight loss and successful obesity treatment may not be the same thing
• Their predictions for what will surprise us five and ten years from now

You’ve hit your goal weight, or you’re close. So why doesn’t life feel as different as you expected? For many people, the number on the scale was never really the point. It was a stand-in for feeling confident, joining in, and finally enjoying life.

Today’s weight loss medications are helping people lose weight that once felt out of reach. A large new BMJ analysis asked whether quality of life is keeping pace, and the answer may make you rethink what success means. Join Holly and Jim as they dig into the findings, why feeling better and weighing less don’t always move together, and share what they’d do about it.

You’ll leave with practical, doable steps you can start now, long before you reach your goal weight. Press play to find out what to work on alongside your weight loss.

Discussed on the episode:

• What a huge new review of nearly 100,000 participants revealed about weight loss and quality of life
• The surprising gap between how much weight people lose and how much better life gets
• Why “quality of life” and “happiness” aren’t quite the same thing, and why the difference matters
• The question Holly asks every patient that gets underneath the number they say they want
• Why waiting to be happy until you reach your goal could work against you.
• A simple fill-in-the-blank exercise to uncover what you really want your weight loss to make possible
• The “life score” you may want to track alongside your weight
• Feeling better but being disappointed is completely normal, and what to do if the medication itself is part of the problem.
• A rapid-fire round that puts the hosts on the spot, including a food noise question Holly says isn’t fair.
• The pattern Holly admits she’s guilty of, and what it means for celebrating your wins

Your friend just started semaglutide. She got it online; it's "compounded," it has B12 in it, and it's only $199 a month. Sounds like a great deal, right? But what exactly is in that vial, who made it, and how much are you supposed to take? More and more people are facing these questions every day, and most of us don't know how to answer them.

Join Holly and Jim as they welcome not one, not two, but three guests for the very first time: Misty Gaddis, pharmacy manager of medication compounding safety; Jessica Pescatore, clinical director of the Alabama Poison Information Center; and Richelle Chambliss, a clinical pharmacist who supports UAB's weight management clinics. Together, they pull back the curtain on compounded GLP-1s and share what your pharmacist wants you to know about weight loss medications, from dosing and side effects to insurance, access, and stopping and restarting. You'll come away with practical questions to ask and red flags to watch for before you inject anything.

Discussed on the episode:

• Why "compounded" doesn't mean "generic," and the common misconception that could put you at risk
• The real reason B12 shows up in so many online semaglutide products (and whether it's doing anything for your weight loss)
• What the Poison Center hears when dosing goes wrong, and why compounded products create a whole new level of risk
• The surprising truth about why the cheapest option may not be the cheapest for long
• A tempting shortcut to save money that pharmacists urge you not to take
• Why the "best" dose may not be the highest one
• What can happen when you stop and restart your medication on your own
• The red flags that should make you pause before taking anything you've ordered online
• The underrated ways your pharmacist can help you succeed, and when to call them
• A question Holly and Jim have never asked in decades of weight loss work, and why it's now on the table

New obesity medications can now produce weight loss once thought impossible without surgery. That success is forcing doctors to ask a question they never had to face before: what if a treatment doesn't know when to stop?

Join Holly and Jim as they unpack six new questions these next-generation drugs have raised in obesity medicine. Using a relatable patient case, they explore the difference between losing the maximum amount of weight and losing the optimal amount, and why those two things are no longer the same. You'll also hear where lifestyle fits into treatment now, what "success" really means when the scale isn't the whole story, and why the answers may ultimately come down to a conversation between patient and provider.

Discussed on the episode:

• Why hitting the weight-loss "ceiling" used to save doctors from a decision they never had to make
• A patient case that reveals what happens when someone loses more weight than she may actually need
• The hidden trade-off between the number on the scale and what's happening to muscle and strength
• Why nutrition and physical activity haven't become less important on these medications, just different
• The rapid-fire round that puts Holly and Jim on the spot with some of obesity medicine's toughest new dilemmas

If losing weight made movement easier, wouldn’t you naturally start moving more? It’s the kind of assumption that feels almost too obvious to question: shed 40 or 50 pounds, and your knees stop aching, the stairs get easier, and you’re out there living more. Holly and Jim certainly believed it. But in the age of GLP-1 medications, where rapid, substantial weight loss is now common, does this assumption still hold up?

In this episode, Holly and Jim put that belief to the test with real data. Diving into three separate studies (including brand-new, cutting-edge research), they explore what happens to physical activity levels once people start losing weight on GLP-1s. The results might surprise you, and as Jim warns early on, they might leave you feeling a little deflated too. But stick around, because Holly and Jim don’t just deliver the bad news; they explain why it matters and what you can actually do about it.

Discussed on the episode

• The surprising step-count numbers researchers found when they measured GLP-1 users with wearable devices and why the results left Jim unimpressed.
• What happened when scientists tracked the same people’s activity levels before and after starting a GLP-1 medication (hint: it wasn’t what anyone expected)
• Why a control group matters so much in this kind of research, and what’s still missing from the picture
• The difference between “free living” activity and structured exercise, and which one may be quietly declining
• A few theories on why physical activity might dip on these medications, and why even Jim isn’t fully convinced by any of them
• Five practical strategies for making sure your activity level doesn’t get left behind while the pounds come off
• Holly and Jim’s honest, personal reactions to research that challenges something they’ve believed for years

Everyone knows GLP-1 medications help people eat less. But does eating less actually mean eating better? It’s a question the weight loss field never really had to ask before, and the answer might surprise you.

Join Holly and Jim as they dig into three GLP-1 studies looking at what people are actually eating. You’ll hear the real numbers behind diet quality, protein intake, and nutrient gaps on these medications, plus what it means for anyone currently taking (or considering) a GLP-1. Holly and Jim also share five practical tips to help ensure your diet works as hard as your medication is.

Discussed on the episode

• Why losing weight on a GLP-1 doesn’t automatically mean you’re eating a healthier diet
• The surprising “Healthy Eating Index” scores researchers found in people taking these medications.
• Which micronutrients tend to slip through the cracks when food intake drops
• The protein timing pattern showing up in the data and why it might matter.
• Whether cravings actually go away on GLP-1s, or if that’s a myth
• Five things anyone on a GLP-1 can do right now to protect their diet quality
• Answers to listener questions on appetite loss, ongoing hunger, and whether there’s a “best” GLP-1 diet
• A teaser for the next episode, which flips the lens to physical activity on GLP-1s

Think you know what it takes to keep weight off? Most people can tell you how to lose weight, but ask them what actually predicts keeping it off, and the answers get shaky fast. That’s a problem, because losing weight and maintaining weight loss are two completely different biological and behavioral games, and confusing the two is one of the biggest reasons people yo-yo.

In this episode, Holly and Jim put their listeners to the test literally. They’ve built a 20-question pop quiz covering everything from the hidden biology of metabolic adaptation to the real findings from the National Weight Control Registry, the groundbreaking study Jim co-founded three decades ago. And because so much has changed recently, they’re also tackling the question everyone’s asking: does any of this still apply in the age of GLP-1 medications?

Grab a pen (or play along in your head) and see how many you get right. Some answers might surprise you, and a few might change how you think about your own weight loss journey for good.

Discussed on the episode:

• Why the biology of losing weight and the biology of keeping it off are two entirely different processes, and why not knowing this is setting you up to regain
• What really happens to your metabolism after weight loss, and whether “metabolic adaptation” is something you should actually be worried about
• The hunger hormone changes that don’t go away and what that means for your day-to-day life
• The real math behind the “energy gap,” a concept Jim and Holly coined themselves
• What the National Weight Control Registry’s 30,000+ members actually do differently, including the surprisingly unglamorous form of exercise most of them rely on
• Whether successful maintainers take weekends and holidays “off” from their habits
• The truth behind the infamous “95% of diets fail” statistic.
• Whether losing weight slowly really does make you more likely to keep it off.
• Why willpower isn’t the key predictor of long-term success and what is
• What happens to the body when someone stops taking a GLP-1 medication, and whether that counts as the medication “failing”
• The most vulnerable window for regain during medication-assisted weight loss and why most people prepare for the wrong phase
• A rapid-fire round covering daily weighing, running vs. walking, and the most overrated maintenance strategy out there

What did humans actually evolve to eat? With paleo, keto, vegan, Mediterranean, and a thousand other diets all claiming to be "the one," it's no wonder people feel whiplashed every time they walk into a grocery store. But what if the answer isn't found in the latest diet book, but in millions of years of human evolution?

Join Holly and Jim as they welcome back Harvard evolutionary biologist Dan Lieberman for a second appearance on the show. This time, Dan isn't talking exercise. He's talking food. Drawing on his new book, "Fed Up: What Evolution Reveals About Food, Diet, Health, and Eating Well," Dan explains why there's no single "evolutionary diet," why our supermarkets are a completely unprecedented environment for the human brain, and why willpower alone was never going to be enough. And because Dan doesn't just study diets, he lives them. He shares the surprisingly rough personal experiments he and his wife put themselves through in the name of research.

By the end of this episode, you'll understand exactly why eating well feels so hard in the modern world, and why that struggle has nothing to do with a lack of discipline.

Discussed on the episode:

• Why an evolutionary biologist says there's no such thing as "the" diet humans evolved to eat
• The "naturalistic fallacy" and why what our ancestors did isn't automatically what we should do
• What happened when Dan and his wife tried a raw food diet for several days (and why it ended with a bagel)
• The one natural food that's high in both sugar and fat, and what it reveals about why we crave certain foods
• How food processing quietly changed what's actually in your food, long before you ever open the package
• Why Dan calls modern ultra-processed foods "hyper-matched" to our brains
• The real reason low-carb and low-fat diets can both work, and why neither is right for everyone
• What Dan learned trying the Atkins diet as a self-described "carboholic"
• Why the Mediterranean diet keeps coming out on top, and whether that's fair to other traditional diets around the world
• His take on the vegan vs. carnivore debate, and why he wouldn't attempt one of them
• A listener's question about why the same diet can work great for one person and fail for their sibling
• Practical advice for eating well on a tight grocery budget
• The one thing Dan wants every listener to remember about their own struggles with food.

Most people trying to lose weight obsess over the what: what diet, what medication, what workout plan. But according to Holly and Jim, the real key to long-term success isn't found in any of those choices. It's found in a set of decisions most people never even realize they're making.

In this episode, Holly and Jim count down the 10 decisions that determine whether a weight loss journey actually sticks. Some are questions you'd expect. Others might catch you completely off guard, including the one they say most listeners will never predict is number one.

Whether you're just starting, deep into a GLP-1 medication, working to maintain weight you've already lost, or wondering if you're on the right plan at all, this countdown is built for you. So before you make your next move, find out if you've quietly been making these decisions by default or on purpose.

Discussed on the episode:

• The very first decision Holly says most people skip entirely and why it might surprise you coming from two people who host a weight loss podcast.
• Why a number on the scale might not mean what you think it means, and what "success" should really be measured by
• A newer, often-overlooked decision that's only become critical in the age of powerful weight loss medications
• The mindset shift that separates people who keep weight off from those who regain it
• Why hitting a plateau might actually be a sign you're succeeding, not failing.
• The surprising, deeply personal decision Holly and Jim rank as number one one they say most listeners will guess wrong

For years, the ceiling on medical weight loss was 15%, maybe 20% if you were lucky. Now a new triple-target medication is posting average results that flirt with 30% body weight loss in clinical trials, numbers once reserved for the operating room. Holly and Jim sat down to unpack what's driving these results, and found themselves asking a question neither expected to ask in their careers: how much weight loss is actually too much?

Retatrutide, the drug at the center of this episode, adds a third receptor target to the GLP-1 and GIP combination already familiar to listeners. Holly and Jim break down what this third piece brings to the table, walk through the newest published and presented trial data, and get refreshingly honest about the parts of this "medical miracle" that keep them up at night.

More weight loss isn't automatically better weight loss. As these medications get more powerful, Holly and Jim argue the field needs to catch up fast on nutrition, dosing, and what "success" even means going forward. If you've been following the GLP-1 story, this episode is the plot twist you didn't see coming.

Discussed on the episode:

• What makes this new medication a "triple agonist," and why adding a hormone best known for raising blood sugar might actually help with weight loss.
• The eye-opening trial results that have researchers using words like "mind-blowing" and why the number didn't plateau the way older treatments do
• A surprising new clinical worry that Holly never thought she'd hear herself say out loud
• Why "maximum dose" might not be the right goal for most people, even though it produces the biggest numbers
• The uncomfortable side effect that showed up more with this medication than with anything else on the market
• Whether switching medications is a good idea if what you're currently using is already working.
• The philosophical question Holly and Jim now find themselves asking about appetite itself and why silencing it completely might not be a win.
• A hint at what's coming next in obesity treatment, involving a hormone that hasn't entered the conversation yet

Can simply paying attention to your first bite of food change how much you eat? It sounds too simple to matter, but Holly and Jim are digging into a topic that might seem completely outside their lane: mindfulness and meditation.

For years, mindfulness has been filed under "stress management," not "weight management." But a growing body of research is asking a bigger question: can training the mind actually change the way we eat, not by altering our biology, but by changing how we respond to it? Holly and Jim break down a recent meta-analysis of dozens of studies to find out what's real, what's hype, and where this surprisingly powerful tool might fit into your own weight loss journey, especially the part everyone struggles with most: keeping the weight off.

Tune in as Holly and Jim separate the science from the sales pitch, tackle listener questions, and even reveal a personal update that might surprise you.

Discussed on the episode

• Why "eating on autopilot" happens to all of us and the moment Holly realized she was already halfway through a road trip sandwich she didn't remember eating
• The surprising reason automatic eating exists in the first place (hint: it's not laziness)
• What a 46-study meta-analysis reveals about mindfulness and eating behavior and why the effect is small but might matter more than you'd think
• Why this tool may matter far more for keeping weight off than for losing it in the first place
• The key difference between mindfulness and meditation (and why they get confused)
• A concept called "decentering" that could change the way you handle cravings
• Whether mindful eating is secretly just another diet in disguise
• One simple, five-minute-a-day habit almost anyone can start today.
• A rapid-fire round covering hunger vs. habit, biology vs. behavior, and myths about needing to "sit quietly with your eyes closed"
• A personal confession from Jim about a new daily practice he's been keeping quiet about

A few clicks online. No exam, no phone call, no video visit. Minutes later, a GLP-1 prescription is headed to your door. It sounds like the future of healthcare: fast, easy, convenient. But is convenience the same thing as care?

A Yale research team wanted to find out, so they built a fake patient, sent her to 49 different online GLP-1 providers, and tracked exactly what happened. What they found may change the way you think about getting these medications online and raise questions you didn't know to ask.

Join Holly and Jim as they unpack this eye-opening "secret shopper" study and use it to explore a much bigger question: when does convenience actually improve obesity care, and when does it quietly replace it? Whether you're currently taking a GLP-1, considering one, or just curious about where obesity treatment is headed, this episode will change how you evaluate any provider online or in person.

Discussed on the episode:

• The surprising percentage of online providers that approved a prescription in some cases in under five minutes
• The critical questions almost none of the 49 companies bothered to ask before prescribing a powerful medication
• Why "getting the meds" and "getting obesity care" are two very different things
• The real risks of starting a GLP-1 without a proper medical evaluation
• What compounded GLP-1s are, and why the vast majority of online prescriptions turned out to be compounded rather than brand-name
• Why your primary care doctor absolutely needs to know you're taking one of these medications (even if your online provider never asks)
• The dose-escalation practice that has Holly worried and why more medication isn't always better
• Holly and Jim's personal, unscripted stories about when convenience backfired in their own lives
• A simple framework for evaluating whether an online (or in-person) provider is actually giving you the care you deserve

For years, patients kept telling Holly the same strange thing: it wasn't the number on the scale that changed their life, it was something quieter, something they'd never had words for. They just didn't think about food anymore.

Now that experience has a name, and for the first time, a way to measure it. Food noise has gone from an offhand comment on social media to one of the most talked-about concepts in obesity science, and Holly and Jim are back to unpack how far the research has come since they last covered it.

Join Holly and Jim as they revisit food noise with fresh eyes. You'll hear how a handful of scattered patient stories turned into a full-blown scientific movement, what the newest validated tools can actually tell us, and why this "invisible" part of obesity might reshape how we think about treatment for years to come. Along the way, Holly and Jim get personal, sharing their own honest (and sometimes surprising) answers to whether they experience food noise themselves.

Discussed on the episode:

• How an unexpected side effect of GLP-1 medications turned into a full-blown scientific mystery
• The difference between food noise, hunger, and cravings, and why it matters more than you'd think
• Two newly validated tools researchers are using to measure something patients have described for years.
• A surprising decades-old study that raises the question: is food noise really new?
• A science-backed framework for understanding where food noise comes from in the brain
• Whether food noise could predict who regains weight, and who doesn't
• The big philosophical question: could reducing food noise become a treatment goal, even for people who don't need to lose weight?
• Holly and Jim's own personal, no-holds-barred answers to "do you have food noise?"
• What might happen to food noise if you stop taking a GLP-1 medication, and whether that means treatment "failed"

GLP-1 medications are the single most requested topic on the show, no contest. But with so much noise on social media, in doctors' offices, and everywhere in between, sorting fact from fiction has never been trickier. Some of what's out there is spot-on. Some of it is dangerously wrong.

So this week, Holly and Jim are flipping the format. Instead of another lecture, they're putting GLP-1 knowledge to the test with a 20-question quiz covering everything from the basic biology of these medications to the questions doctors themselves don't always get right. Grab a pen, keep score, and see how you stack up.

By the end of this episode, you'll have a clearer, science-backed answer to the questions you've been too afraid to ask or too confused by conflicting headlines to trust.

Discussed on the episode:

• The surprising truth about what GLP-1 medications are actually doing to your body (hint: it's not what most people think)
• Whether feeling less hungry is really a sign the medication is "working"
• Why a stalled scale might be the most normal thing that could happen to you
• The dosing myth that even well-meaning doctors sometimes get wrong
• What "success" really looks like when two people lose very different amounts of weight
• The truth behind "Ozempic face" and hair loss and whether the meds are really to blame
• Why almost everyone on a GLP-1 could benefit from one specific type of healthcare provider
• What to actually do (and not do) if you're eating less than 800 calories a day and still feel fine
• The real answer to "can I ever come off the medication?"
• Why those "natural GLP-1" gummies and supplements deserve a healthy dose of skepticism

We've all felt it: you decide to eat healthier, open social media, and within minutes, you're drowning in contradictory advice. Eggs are back. Butter's healthy. Seed oils are toxic. Never eat after 7pm. Wait, only eat between noon and 6pm? By the end, you're left wondering if anyone can just tell you what to eat.

Join Holly and Jim as they sit down with award-winning food journalist and registered dietitian Carolyn O'Neil to unpack why nutrition advice feels so exhausting and contradictory. With decades spent translating nutrition science for CNN and beyond, Carolyn has made a career out of turning "pie in the sky" science into "pie on the plate" advice people can actually use. In this conversation, she shares how to separate real science from clickbait, why food doesn't have to be the enemy, and how her philosophy of "the more you know, the more you can eat" can transform your relationship with food.

Whether you're confused by conflicting headlines, navigating a GLP-1 journey, or just trying to enjoy a family celebration without guilt, this episode is packed with practical, joyful wisdom from one of the most trusted voices in nutrition communication.

Discussed in the episode

• Why the two biggest buckets of nutrition headlines are "this will kill you" and "this will cure you," and why it's often the same food
• A simple media literacy trick for telling real science from a misleading headline
• What really happened in a viral study on omega-3 supplements and brain health
• Why the "Mediterranean diet" is more romanticized than most people realize
• How to keep the joy of eating alive while on a GLP-1 medication
• The restaurant industry's surprising response to guests eating less
• A simple framework, "the three M's," for personalizing your approach to health
• Why "shop the perimeter of the store" might be terrible advice.
• Carolyn's rapid-fire answers on the most overhyped nutrition claims, misleading headlines, and her favorite food city in the world
• A practical tip for enjoying food-centered family traditions without overeating or guilt

Cancer is the disease most people fear. But heart disease is the one that actually kills the most Americans, and most people never connect it to their weight. For decades, obesity was treated as a bystander to heart disease, a risk factor at best. That thinking has changed dramatically, and the data behind that shift is stunning: we now have a medication proven to cut major cardiovascular events by 20% in people with obesity.

Join Holly and Jim as they sit down with an old friend and true legend in the field, Dr. Robert Eckel, Professor Emeritus at the University of Colorado Anschutz Medical Campus. Bob is the only person to have ever served as president of the American Heart Association, the American Diabetes Association, and the Obesity Society, a hat trick that connects heart, metabolism, and weight in a way no one else in medicine can claim. He's been in the room for four decades of major turning points in this field, from the earliest meetings on obesity science to the current GLP-1 era.

In this episode, Bob walks Holly and Jim through the science, the skepticism, and the surprises behind the biggest shift in obesity treatment of their careers and answers real listener questions about medications, guidelines, and what patients should actually be asking their doctors.

Discussed in the episode:

• The pivotal trial that's changing how cardiologists think about weight loss drugs and how its results stack up against statins
• Why the outcome researchers expected to explain the benefits of these medications may not be the real story at all
• The surprising history of how "obesity" and "heart disease" became connected in medical thinking, and who had to make the case
• What your body's "set point" really is, and whether staying on medication long-term can actually change it
• A candid take on whether the weight-loss drugs might be helping or quietly working against long-term behavior change
• Real listener questions answered, including when a cardiologist won't prescribe, what "not overweight enough" really means, and whether weight loss "worked" even after a heart attack.
• Bob's own vulnerable reflections on his career, a decision he'd make differently, and what still keeps him "rewired" in retirement

For decades, one number has ruled the world of fitness: 10,000 steps. It's on your watch, your phone, maybe even tattooed into your daily to-do list. But what if that number was never based on science at all?

Join Holly and Jim as they sit down with Dr. Amanda Paluch, Associate Professor of Kinesiology at the University of Massachusetts Amherst and leader of the Steps for Health Collaborative, an international research consortium pooling data from over 125,000 adults to answer one deceptively simple question: how many steps do you actually need? Amanda pulls back the curtain on where the 10,000-step goal really came from, what the data shows instead, and why the "right" number might depend on how old you are. Whether you're chasing a step count, recovering from mobility limitations, or navigating GLP-1 medications, this conversation will change the way you think about your daily walk.

Discussed in the episode:

• The surprising 1960s marketing origin of the 10,000-step goal (hint: it has nothing to do with health research)
• Why the "right" step goal may look different depending on your age
• The step range where most of the cardiovascular benefit shows up (it's lower than you'd think)
• Whether walking pace matters as much as total volume
• How do steps fit into the GLP-1 conversation?
• What the research says about step counting becoming an unhealthy obsession
• Practical advice for people with mobility limitations who feel like step goals are out of reach
• Rapid-fire answers on walking vs. running, treadmill vs. outdoor steps, and more
• A simple mindset shift for anyone having a "low step day"

For 40 years, every time nutrition has found a new villain, the food industry has handed us a new label to go with it: non-fat, no GMOs, gluten-free, no seed oils, and now, non-ultra-processed. We have more experts, more studies, and more food rules than ever before, so why does standing in the grocery aisle still feel like such a guessing game?

Join Holly and Jim as they sit down with Tamar Haspel, the James Beard Award-winning Washington Post columnist behind Unearthed and author of To Boldly Grow, to pull apart the ultra-processed food debate and ask whether today's labels are actually helping us eat better or just making us easier to market to. Tamar doesn't just write about food from behind a desk: she gardens, fishes, raises chickens, and runs an oyster farm on Cape Cod, and she brings three decades of reporting, real skepticism, and zero patience for diet cranks to the conversation.

You'll hear why the food world keeps repeating the same mistake, what a cage full of B.F. Skinner's pigeons can teach us about our relationship with food, and what's really driving overeating once you strip away the marketing.

Discussed on the episode:

• The decades-old pattern that explains why every new food "villain" feels eerily familiar
• The bizarre pigeon experiment that reveals why we're so convinced certain foods are "good" or "bad" for us
• Why a bowl of crushed cereal proved more about overeating than years of processed-food headlines
• The blunt case for why "everything in moderation" might be the most useless diet advice out there
• The one-sentence grocery store rule that could replace almost every food label you've ever side-eyed
• How GLP-1 medications could end up reshaping the entire food industry, not just individual waistlines
• The "healthy" nutrient claim, Tamar says, is wildly overrated and the snack everyone blames for something it's not even guilty of

Losing weight on a GLP-1 medication can feel like magic until the scale stops moving. For almost everyone on these drugs, there comes a moment when the rapid progress slows, then stalls completely. Is the medication failing? Has your metabolism adapted? Did you do something wrong? For most people, that moment feels like a problem. It isn't.

Join Holly and Jim as they unpack one of the most misunderstood parts of the GLP-1 journey: the shift from losing weight to keeping it off. You'll discover why a stalled scale is actually a sign the medication is doing exactly what it's supposed to do, and why "maintenance" is a completely different physiological state than "weight loss." One that comes with its own rules. Along the way, you'll pick up science-backed (and some still-unanswered) guidance on nutrition, muscle, bone health, and motivation for the long haul, plus a clear answer to a question Holly says she gets all the time: Are they against staying on these medications long-term?

Discussed on the episode:

• Why hitting a plateau on a GLP-1 is good news, not a sign the drug has stopped working.
• The blood pressure pill comparison that reframes what people call "drug resistance"
• Why nutrition may matter even more, not less, once weight loss stops
• Whether you actually need to exercise to keep weight off on a GLP-1 (the honest answer might surprise you)
• The bone health risk in younger women that's getting far less attention than muscle loss
• Why are dose-tapering and switching strategies being called the "Wild West" of GLP-1 care
• A New York Times claim about these medications "rewiring the brain" and what that could mean long after you stop.
• How to find motivation once the scale refuses to budge

Have a question or a success story? Send it in. Holly and Jim read every one, and they're especially looking for listener stories about navigating weight loss maintenance.

What if the biggest obstacle to your health isn't your willpower, it's your zip code? Most of us have been raised to believe that weight and health come down to personal choices: what you eat, how much you move, how disciplined you are. But what if the deck has been stacked against millions of Americans before they ever make a single decision?

This week, Holly and Jim sit down with Dr. Christina Economos, Dean of the Friedman School of Nutrition Sciences and Policy at Tufts University, to explore one of the most important  and most overlooked dimensions of the obesity epidemic: the environments we live in. With decades of groundbreaking research behind her, including the landmark Shape Up Somerville study, Dr. Economos makes a compelling case that lasting health change can't happen one person at a time.

And with GLP-1 medications reshaping what's possible for individual weight loss, the conversation has never been more urgent. Does community still matter when we have powerful new treatments? Dr. Economos has a clear answer, and it just might change how you see your own role in the bigger picture.

Discussed on the episode:

• The landmark study that proved community-wide obesity prevention actually works in the real world, and the surprising ripple effect it had beyond the children involved.
• Why your zip code may predict your health outcomes nearly as powerfully as your genetics
• The hidden forces in your neighborhood that are quietly shaping what you eat and how much you move, often without you realizing it
• What a food environment assessment in the Mississippi Delta revealed perfectly captures the challenge millions of Americans face daily
• Why fixing schools alone won't fix childhood obesity, and what actually needs to happen instead
• The honest answer to how much of the obesity epidemic is biology versus environment (hint: it's not a clean split)
• The key ingredients, Dr. Economos says, every successful community health intervention must have, and the #1 mistake researchers keep making
• How GLP-1 medications and community health are more connected than you might think
• What "spark plugs" are, why every successful health movement has had them, and whether you could be one
• Real U.S. communities that are getting this right and what they're actually doing differently
• Practical steps anyone can take right now, even if your environment is working against you

If you've spent years hopping from one diet to the next: low fat, then low carb, then keto, then intermittent fasting, you're not alone, and you're not failing. The truth is, the diet world has been cycling through the same promises, the same villains, and the same disappointments for nearly a hundred years. And most of us never stop to ask why.

Join Holly and Jim as they do something they've never done before on the show: step back and take a decade-by-decade look at almost 100 years of dieting history. From the 1930s to the GLP-1 era of today, they trace how we went from counting calories to carnivore diets  and what it all actually taught us (or didn't).

This one is equal parts fascinating, a little humbling, and surprisingly fun. Whether you're a diet history nerd or just someone who's tired of starting over, this episode will change the way you think about every diet you've ever tried.

Discussed on the episode:

• The three-category system Holly and Jim use to classify every diet, and why one category might describe your current eating plan
• The diet from the 1930s that your favorite wellness influencer is basically still selling today
• Why the decade that got everyone obsessed with fat-free foods may have actually made obesity worse
• The weight loss medication that came before GLP-1s, and the dramatic reason it was pulled from the market
• Which diets from the last 100 years actually have the science to back them up
• The rapid-fire verdict: best diet, biggest mistake, and most underrated program of the century
• What GLP-1 medications are changing about the way we think about diets, and why Holly has one big worry about where this is all heading
• Jim's closing thought that reframes everything you think you know about why diets succeed or fail

Millions of people are now taking GLP-1 medications and losing weight, but is eating less the same as eating better? The answer, according to today's guest, is a resounding no. And almost nobody in medicine, food, or public health is talking seriously about what happens when appetite disappears, but nutritional needs don't.

Join Holly and Jim as they sit down with Dr. Maha Tahiri, a nutrition scientist, food industry strategist, and founder of Nutrition Sustainability Strategies, for one of the most eye-opening conversations in the GLP-1 era. Maha has spent decades at the crossroads of nutrition science, public health, and food innovation, and she's now helping companies around the world rethink what it means to nourish a consumer who's eating dramatically less. Her new company, S2B, is building a strategy for the GLP-1 era and beyond, and she's asking the questions that urgently need answers.

This episode will change how you think about GLP-1 medications, food, and what it truly means to be well-nourished.

Discussed on the episode:

• Why eating less on GLP-1s does NOT mean you're eating better and the nutritional crisis hiding in plain sight
• The alarming statistic about how many GLP-1 users are falling short on fiber, protein, and key micronutrients
• Why Maha calls what's happening to GLP-1 users "medically induced malnutrition" and why that phrase should get your attention
• The one behavior Holly says is now more important on GLP-1s than ever before (not what most people expect)
• Why fiber deserves its own strategy and why lumping it in with protein is a mistake.
• The three phases of GLP-1 use that should shape everything you eat
• What a strange debate in Botswana had to do with Maha's entire career pivot
• The unexpected food category that's actually thriving because of GLP-1 users
• Why the food industry may owe pharma a thank-you and what it needs to do with its second chance
• The role AI is now playing in nutrition advice, and why Maha thinks that's actually good news
• Maha's rapid-fire picks: the most underrated nutrient, the most overrated trend, and the one food she'd put in every kitchen.

What if the medications changing everything about obesity treatment are also creating problems nobody saw coming? We’re living through a genuine before-and-after moment in obesity medicine. Drugs that once seemed like science fiction are now producing 20, even 25% weight loss in real patients. But the questions piling up are just as staggering as the results: What happens to your muscle? Your bone? Your sense of self? And what happens when the medication stops?

Holly and Jim sit down with Dr. Ken Fujioka, an endocrinologist, director of the Nutrition and Metabolic Research Center at Scripps Clinic, and one of the very first physicians to build an entire career around treating obesity, long before it was popular or even respected. He’s run over 100 clinical trials, treated thousands of patients a month, and watched this field go from Fen-phen clinics to GLP-1 breakthroughs. If anyone has the perspective to separate the genuine revolution from the hype, it’s Ken.

This episode is a masterclass in what actually happens in the exam room, not in a clinical trial, not in a headline, but with real patients facing real tradeoffs. Ken is refreshingly practical, deeply experienced, and not trying to win any argument. He’s just trying to help people build healthier lives in the middle of one of the fastest-moving moments medicine has ever seen.

Discussed on the episode:

• Why a shortage revealed a danger nobody was talking about, and why emergency rooms are still seeing the consequences
• The patients who are actually reaching their goal weight for the first time ever (and what that creates as the new problem to solve)
• What Ken tells patients who want to reduce or stop their medication, and the pattern he keeps seeing a few months later.
• The one group of patients he’s seen keeps the weight off without staying on the drugs, and what might explain it.
• Why losing weight faster is one of the biggest mistakes being made right now, and what the bariatric surgery literature has been telling us for years
• How Ken decides which medication to prescribe and why insurance coverage is always the first question
• The muscle loss conversation: why it’s like pulling teeth, and the one thing he’s considering making non-negotiable
• What the next generation of obesity drugs looks like, and the hormone that once seemed like a crazy idea that now has Ken most excited
• His rapid-fire answers: the most underrated obesity treatment tool, the biggest mistake clinicians make, and the one thing patients should protect above everything else
• The single thing Ken hopes every listener walks away remembering

Everyone has been burned by nutrition advice that completely reversed itself a few years later. Eggs were dangerous, then essential. Butter was poison, then practically a health food. Fat was the enemy until we realized what replaced it might have been even worse. If you've ever thrown up your hands and wondered whether nutrition scientists agree on anything, you're not alone.

What if the confusion isn't just about changing science but about how nutrition guidelines are made, who influences them, and why the U.S. and Europe keep landing in different places? In this episode, Holly and Jim sit down with one of the world’s most influential nutrition scientists, Dr. Arne Astrup, to pull back the curtain on decades of dietary dogma, trace how some of our biggest nutritional mistakes happened, and explore where the science is actually heading.

Dr. Astrup has chaired the Nordic Nutrition Recommendations, led one of Europe's top nutrition research departments, and published over 700 scientific papers. He's also someone who has never been afraid to challenge the consensus, long before it was popular to do so. If you want to understand why nutrition science feels so chaotic, and what you should actually be eating, this conversation is your roadmap.

Discussed on the episode:

• The surprising historical event that set off decades of misguided dietary advice, and the real culprit that was overlooked
• Why the margarine push that replaced butter may have done far more damage than the food it was meant to replace
• The simple shift in thinking that makes navigating nutrition less complicated, not more
• Why Dr. Astrup says we should stop talking about saturated fat entirely
• The counterintuitive truth about full-fat cheese, yogurt, and eggs, and what the latest U.S. dietary guidelines finally got right
• A famous olive oil "fact" that will make you question everything you thought you knew about saturated fat
• Why the popular ultra-processed food classification may be doing more harm than good, and what a Harvard professor says is the real problem ingredient.
• The hidden nutritional crisis quietly unfolding among people on GLP-1 medications
• What industry-funded nutrition research actually looks like, compared to publicly funded studies (the answer may surprise you)
• Rapid fire: the most misunderstood food in America, the one thing Americans obsess over that barely matters, and the health food Dr. Astrup is most skeptical about

You've heard it before. A friend, a coworker, or your own mother swears by something, and the proof is standing right in front of you. She lost 30 pounds. You've seen it. You know it's real. So why aren't you doing it too?

Here's the thing: personal success stories are powerful precisely because they're real. But real doesn't mean the whole picture. And in the world of weight loss, acting on the wrong part of a true story can quietly pull you off track, not because you were fooled, but because no one told you what was missing.

In this episode, Holly and Jim break down the science of why anecdotes feel so convincing, and give you a practical framework for turning "my friend lost 30 pounds doing this" into something you can actually use  without falling into the traps that catch almost everyone.

Discussed on the episode:

• The six ways a real, true story can still mislead you, and the scientific terms that explain exactly why
• Why the people who didn't get results are almost never the ones you hear from
• The surprising reason your friend may have lost weight on keto that had nothing to do with keto
• What apple cider vinegar actually does (and doesn't do) for weight loss
• The questions Holly always asks when a patient walks in, swearing by something new
• How to respond when someone you trust is completely convinced that something worked without damaging the relationship
• When you should sit up and pay attention to an anecdote, and when to be suspicious
• The one red flag that should always make you pause before trying something new

Exercise is good for you. But good for your mood? Your brain? Science has now weighed in, and the answer might surprise you more than you'd expect.

Join Holly and Jim as they dig into the most comprehensive review ever conducted on exercise and depression, a sweeping 2026 Cochrane analysis of 73 randomized controlled trials and nearly 5,000 people. This isn't feel-good advice; it's hard data. Discover why taking action through movement can benefit your mental health, no matter your role or experience, and why it's time to prioritize exercise for your mind.

Along the way, Holly and Jim go beyond the science to tackle the real challenge: knowing exercise helps is one thing, but actually doing it when you're at your lowest is another. They share practical, compassionate strategies for getting off the couch  even when depression is telling you not to.

Discussed on the episode:

• How exercise stacks up against antidepressants (the results will raise your eyebrows)
• Why "moderate" is actually a powerful word when it comes to science
• The reason you can't just tell a depressed person to "go for a walk" and what to say instead
• Why you should need a doctor's note not to exercise
• The surprising truth about whether more intense exercise is actually better for your mood
• Holly's "10-minute rule" - a simple trick for when you truly cannot get off the couch
• What does it mean if you feel like you "need" exercise to feel okay
• The one thing Jim wishes every doctor would bring up when treating depression

Have you ever wondered why the same advice that worked perfectly for your friend did absolutely nothing for you? What if the problem isn't your effort, your commitment, or even the advice itself, but rather the body you're living in?

Holly and Jim tackle one of the most misunderstood topics in weight management: the gap between what feels obviously true and what's actually universal. If you've never struggled with your weight, some things just seem like common sense. However, for millions of people, this "common sense" doesn't align with their lived experience, and there's a biological reason why. This episode represents a significant shift in perspective that could alter the way you perceive yourself, your struggles, and the people around you.

Whether you've battled your weight your whole life or you've never given it much thought, this conversation will challenge what you think you know  and open the door to something far more useful than judgment.

Discussed on the episode:

• The one word that explains why weight loss advice works for some people and completely fails others
• Why "just eat less and move more" is technically correct and almost entirely unhelpful.
• What a yogurt and an old medication taught Holly about how different bodies really are
• The concept of "food noise" and why some people can't even imagine what it feels like
• Why the number on the scale might be the worst goal you can set
• What the new generation of GLP-1 medications is revealing about biology that we couldn't see before
• How your metabolism is like a thumbprint and what that means for your weight loss strategy
• The uncomfortable truth about why well-meaning advice from lean people often misses the mark

For decades, the message has been simple: if you want to lose weight, you need to exercise more. But what happens when a medication can do the heavy lifting for you? GLP-1 drugs are reshaping everything we thought we knew about weight loss, and that means the role of exercise is changing, too. Not disappearing. Changing.

Join Holly and Jim as they sit down with Dr. Renee Rogers, senior scientist at the University of Kansas Medical Center and expert in biobehavioral lifestyle interventions, to explore this new frontier. If you've ever struggled to stick with exercise, felt guilty for not doing enough, or wondered whether movement even matters now that medications like Ozempic and Wegovy exist, this conversation was made for you.

The answer isn't what you'd expect. Exercise isn't less important in the age of GLP-1s. It's more important just for entirely different reasons.

Discussed on the episode:

• The one word that could completely transform your relationship with exercise
• Why losing muscle during weight loss isn't always the crisis people think it is (but also why you shouldn't ignore it)
• The surprising link between fatigue on GLP-1 medications and physical activity levels
• Why cardio vs. strength training is the wrong question to ask (and what to ask instead)
• The exercise myth Dr. Rogers would delete from the internet forever
• How the timing of your GLP-1 dose might affect when you should work out
• What to focus on after you've hit your goal weight

You hit your goal weight. Then, hunger crept back in, your energy dropped, and the scale rose. Sound familiar? You're not broken, your body is built for this.

In this episode, Holly and Jim sit down with Dr. Rudy Leibel, one of the most influential obesity researchers in history, a Columbia University scientist whose team cloned the leptin gene and fundamentally changed the world's understanding of obesity. What was once dismissed as a willpower problem, Dr. Leibel helped prove is a deeply biological one. And his groundbreaking work laid the foundation for the very GLP-1 medications making headlines today.

If you've ever felt like your body is working against you, this episode will explain how your body’s biology impacts weight, share practical strategies for managing it, and offer real reasons for optimism about what's coming next.

Discussed on the episode:

• The evolutionary reason your body panics the moment you start losing weight
• Why the biological drive to regain never truly lets up, and what successful "maintainers" are actually doing differently
• The surprising reason metabolic adaptation may not predict who regains weight
• What "threshold" vs. "set point" means for your biology and why the distinction matters
• Why GLP-1 medications are more like aspirin for a fever than a true fix for the underlying biology
• The next frontier in obesity treatment that the pharmaceutical industry hasn't fully tackled yet
• What yo-yo dieting on a GLP-1 could mean for your body, and when it becomes a real concern.
• The honest answer to: "Do I have to be on semaglutide forever?"
• At what age does obesity risk "lock in" for kids, and what should parents actually do about it
• Whether there will ever be a single solution to obesity (Dr. Leibel doesn't hold back)
• What Dr. Leibel is doing with the next decade of his career, and why it involves growing brain cells in a dish

You've probably told yourself the story before: "I'm just lazy. I should want to exercise. Something must be wrong with me." But what if science says you're not lazy at all? What if avoiding the treadmill is one of the most deeply human things you can do?

This week, Holly and Jim are joined by Dr. Daniel Lieberman, professor of human evolutionary biology at Harvard University and author of The Story of the Human Body and Exercised. Dan has spent his career studying why humans move the way we do — and more importantly, why we so often don't. His research with hunter-gatherers around the world has turned some of our most cherished fitness beliefs completely upside down. If you've ever felt guilty for skipping the gym, this episode will change how you see yourself.

From the real reason modern exercise feels so unnatural, to what GLP-1 medications are quietly doing to your muscles, to why "no pain, no gain" might be the worst advice in fitness history, this conversation goes deep into the evolutionary science of movement and what it actually takes to build a life where physical activity sticks.

Discussed on the episode:

• The surprising reason no animal on earth exercises except humans (and why that matters for your motivation)
• Why hunter-gatherers sit just as much as we do, but avoid the health consequences we don't
• The real difference between losing weight with exercise and keeping it off, and why the dosage is not the same
• What a study of people running a marathon every day across the United States revealed about behavioral compensation
• The GLP-1 muscle problem no one is talking about, and why exercise may be the only real fix
• Why the treadmill was literally invented as a punishment device (and what that tells us about modern fitness culture)
• The running form insight that could protect your knees and why your cushioned shoes may not be helping the way you think
• What evolution says about the "best" type of exercise for weight management

Every five years, the U.S. government releases dietary guidelines that shape what gets served in school cafeterias, what doctors recommend to patients, and what ends up on your plate. But what actually happens behind the scenes, and who really gets the final say?

If you've ever felt confused about protein, carbs, red meat, or dairy, you're not alone. The latest 2025–2030 Dietary Guidelines for Americans arrived with controversy baked in, with final recommendations that diverged from what the scientific advisory committee actually concluded after two years of rigorous, volunteer-driven research. The result? A lot of frustrated scientists and the public left sorting through mixed messages.

Join Holly and Jim as they sit down with Dr. Christopher Gardner, Professor of Medicine at Stanford University and Director of Nutrition Studies at the Stanford Prevention Research Center. Dr. Gardner served on the 2025 Dietary Guidelines Advisory Committee, giving him a front-row seat to both the science and the politics of how America's nutrition advice gets made. His research has shaped how we think about plant-based eating, diet quality, and what actually works for weight management in the real world. This one gets spicy.

Discussed on the episode:

• The surprising reason why it's nearly impossible to pick Dietary Guidelines Committee members who have zero conflicts of interest
• What 1,000 hours of unpaid volunteer work look like, and what happened when the new administration received the finished report
• The specific recommendation that left nutrition professionals across the board scratching their heads
• Why the protein aisle at your grocery store may be misleading you and what the data actually shows about how much protein Americans eat
• The little-known food group that Dr. Gardner says wins on protein, fiber, AND antioxidants simultaneously.
• Why the "upside-down pyramid" may be more sensationalist than scientific
• The real reason dietary guidelines have "failed" and why it's not the reason most people think
• What Google's free employee cafeteria has to do with fixing America's food system
• Dr. Gardner's unconventional answer to what comfort food means to him

Everything you think you know about weight loss might be wrong, and that's actually great news.

From "my metabolism is broken" to "I just need more willpower," the weight loss world is full of statements that sound completely reasonable, get repeated constantly, and quietly keep people stuck. The problem isn't that people aren't trying hard enough. It's that they're working from a playbook full of myths, half-truths, and oversimplifications.

Join Holly and Jim as they turn the podcast into a game, throwing out the statements they hear most often in the clinic, on social media, and out in the real world, and putting each one to the test: true, false, or it's complicated? Play along at home and see how your answers stack up against two scientists with decades of combined research experience. You might be surprised where you agree and where the science has a very different story to tell.

Discussed on the episode:

• The metabolism myth that makes people feel helpless and the simple fix that actually works
• Why feeling hungry doesn't always mean what you think it means (and when a little hunger might actually be a good sign)
• The truth about GLP-1 medications: what they genuinely fix, what they don't, and the question researchers still can't answer
• How your environment is quietly controlling how much you eat, even when you think you're in charge
• The one thing decades of research agree willpower cannot do on its own
• Why Holly and Jim actually disagree on whether you can out-exercise a bad diet
• The scale question that trips up almost everyone, and the time frame that actually matters
• Why keeping weight off isn't easier after you lose it, but it doesn't have to be as hard as you think.
• The persistent myth that there's one perfect plan out there waiting for you, and what to look for instead

You already know that what you eat matters. But what about how you season it? Most of us reach for the salt shaker without a second thought, but hiding in your spice rack right now could be some of the most powerful, most overlooked tools in nutrition science.

Join Holly and Jim as they sit down with two leading researchers from Penn State University, Dr. Penny Kris-Etherton, one of the most decorated nutrition scientists in the field of diet and cardiovascular health, and Dr. Kristina Petersen, a rising star whose cutting-edge research is changing how we think about flavor, behavior, and healthy eating. Together, they make a compelling case that herbs and spices are far more than a finishing touch. They may be a key to unlocking lasting health.

From inflammation and blood pressure to gut bacteria and appetite, the science behind your spice cabinet is deeper than you ever imagined. And the best part? You don’t need to overhaul your entire diet to start benefiting.

Discussed on the episode:

• The two “big buckets” of how herbs and spices impact your health and why both matter
• Why researchers are moving away from supplements and back to your kitchen cupboard (and the safety concern that’s driving that shift)
• The one spice pairing that makes each ingredient dramatically more effective
• What chili pepper does to your eating speed and why it’s probably not what you think
• The surprising connection between your spice rack and your gut microbiome
• Why sodium reduction doesn’t have to mean flavor reduction and where to start
• The most underrated spices both researchers swear by (you may not have heard of one of them)
• What nutritional belief has each researcher completely changed their mind about over their career

The questions people asked about GLP-1 medications a year ago: Do they work? Are they safe? has been answered. However, a new wave of questions is now emerging, and they're more complex, personal, and in some cases, more surprising than anyone had expected. Something has shifted in the conversation, and Holly and Jim are paying close attention.

When the questions change, that's where the real tension lives. People on these medications are reporting feeling emotionally flat. Others are quietly whispering that they're on drugs at all. Some are obsessing over microdosing, while still others are wondering if eliminating food noise entirely is actually a good thing. These aren't the questions of skeptics; they're the questions of people living with these medications every day. And the science hasn't fully caught up yet.

Join Holly and Jim as they walk through the new frontier of GLP-1 conversations. The ones happening in waiting rooms, on social media, and at dinner parties. This episode doesn't have all the answers, because honestly, no one does. But it will help you ask better questions.

Discussed on the episode:

• The surprising effect of emotional flatness that keeps coming up, why it's not the same as depression, and what people actually mean by it.
• What your brain's reward system has to do with gambling, alcohol, and your afternoon snack
• The oral pill that's generating enormous buzz and the morning routine dealbreaker that comes with it
• Why one of the world's leading researchers would personally choose the shot over the pill
• The microdosing trend that’s taking over social media, and whether there's any real science behind it.
• A thought-provoking question: Is there such a thing as too little food noise?
• "Ozempic face," "Ozempic teeth," and the body changes that are really just weight loss in disguise.
• Why some people are super responders and others barely respond at all, and what to do if you're in the second group
• The reason people still whisper about being on these medications, and why Holly and Jim want that to stop
• A big-picture concern about whether the medical model is crowding out the social one

Most people spend years chasing the “right” weight loss plan, the one diet, the one program, the one secret that finally makes everything fall into place. But what if the reason nothing has stuck isn’t a lack of willpower or effort? What if it’s because you’ve been following someone else’s plan?

Holly and Jim are pulling back the curtain on one of the most liberating truths in weight loss science: maintenance isn’t one-size-fits-all, and the sooner you stop looking for a universal formula, the sooner you can build something that actually works for you. This episode is your permission slip to stop copying and start personalizing.

From three distinct weight loss profiles to three different plan structures, Holly and Jim break down a framework for figuring out where to start and why that starting point matters more than anything else. Whether you’re on a GLP-1 medication, thinking about coming off one, or navigating maintenance without meds, this episode will change the way you think about what “success” actually looks like.

Discussed on the episode:

• The three weight loss profiles and the surprisingly specific clues that reveal which one fits you best
• Why some people lose weight easily but can never seem to keep it off (and the science behind why)
• What “food noise” is, who experiences it most intensely, and why a certain medication makes it disappear
• The truth about precision nutrition and microbiome testing: Are they actually ready to personalize your plan?
• How AI is quietly changing what’s possible in weight loss research (and what Holly and Jim are working on with NIH right now)
• Why the future of GLP-1 medications might look a lot more like “mix and match” than anyone expected
• The one type of person who may be best positioned to transition off weight loss medications successfully
• Three different plan structures to choose from, including one for the overwhelmed and one for the overachiever
• Why a “super friend” might see your biggest weight loss obstacle before you ever do

If you're on a GLP-1 medication or thinking about starting one, there's a good chance you're only seeing half the picture. The media is full of before-and-after stories, but what happens after the after? Most people don't find out until it's too late.

The truth is, GLP-1 medications are genuinely remarkable tools. But tools only work when you know how to use them. And right now, millions of people are stopping their medications, regaining the weight, and walking away convinced the drugs "didn't work" when the real issue was never the medication at all. Join Holly and Jim as they lay out the 12 things every GLP-1 user needs to understand to make their success last. Whether you're just starting out, thinking about stopping, or already dealing with regain, this episode could change everything about how you approach the game.

Discussed on the episode:

• Why weight management is a forever game and why knowing that isn't enough
• The phase of weight loss that experts have been leaving out for years (until now)
• What happens in your brain and body when you stop GLP-1 medication cold turkey
• Why Oprah's experience with willpower is more instructive than you might think
• The one thing Holly says everyone wants, and why chasing it is setting you up to fail
• What "a desirable body state" actually means (hint: it's not the number on the scale)
• The Four E's: the framework for making healthy habits actually stick long-term.
• Why your environment is just as powerful as your physiology and what you can actually do about it
• What Jim tells people who come off medication without a plan (this one is hard to hear)
• The question every listener should ask themselves before they ever step on a scale again

Weight loss isn’t just about the number on the scale. It’s about reclaiming your life. When you’ve been carrying excess weight for years, it’s easy to start accepting limitations as your new normal. Skipping events because of walking. Staying in the car while others explore. Wondering if you’ll see your future grandchildren grow up.

But what if the right support could help your body work with you instead of against you? What if losing weight didn’t have to mean constant hunger and willpower battles? Join Holly and Jim as they sit down with Bill Tollett, a former school principal and coach who lost over 120 pounds and rediscovered what living fully actually means.

This conversation goes beyond the mechanics of weight loss. Bill shares the mental shifts that surprised him most, the challenges of navigating insurance hurdles, and why he now describes himself as feeling “capable” for the first time in decades. Whether you’re considering medication, struggling with where to start, or simply curious about what sustainable change actually looks like, Bill’s story offers honest insights into a journey that’s transformed not just his body, but his entire approach to life.

Discussed on the episode:

• Why one doctor’s blunt comment became the catalyst for change
• The unexpected mental clarity that came with medication (and why it felt like being a superhero)
• How Bill built exercise into his day without joining a gym or running marathons
• The three different reactions people have when they see his transformation
• What “food noise” really feels like and what life is like when it quiets down
• Why Bill says this isn’t cheating, it’s “leveling the playing field.”

Have you ever done everything right, eaten well, moved your body, maybe even started a new medication, and still felt like the system wasn’t working for you? You’re not alone. And the reason might not be what you think.

Join Holly and Jim as they sit down with Dr. Fatima Cody Stanford, an obesity medicine physician and associate professor at Harvard Medical School, and one of the boldest voices shaping how we think about obesity care today. Dr. Stanford treats obesity as the complex, chronic disease it truly is, and she’s not afraid to call out the bias, broken systems, and outdated myths that get in the way. This is a conversation that will change the way you see weight loss, not just as something you do, but as something you deserve support with.

Discussed on the episode:

• The shocking age at which weight bias begins and why it’s not where you’d expect
• Why over 80% of physicians carry bias toward patients with excess body weight, and what one doctor is doing to flip the script
• The real reason GLP-1 medications aren’t the magic bullet and why that’s actually okay
• Why some patients respond brilliantly to these drugs and others don’t, and what you absolutely cannot do to change that
• The one nutrient and one type of exercise that matter most when you’re losing weight on medication
• What happens when insurance pulls the rug out, and the creative strategies doctors use to keep patients on track
• The “Ozempic baby” phenomenon: what the early science is actually showing
• Why the new oral Wegovy pill might not be the game-changer everyone is hoping for
• The grocery store moment that completely changed one doctor’s understanding of obesity

New Year’s resolutions often start with motivation and willpower, but how long does that really last? What if the problem isn’t your discipline, but the world you’ve built around yourself? Your refrigerator, your bedroom setup, even the people you spend time with, are quietly shaping every choice you make.

Join Holly and Jim as they reveal why an environmental detox might be the smartest move you can make this year. Forget juice cleanses and deprivation, this is about redesigning your space and social circle to make healthy choices the easy ones. You’ll learn how your physical surroundings impact everything from late-night snacking to your morning mindset, and why even GLP-1 users shouldn’t skip this critical step.

Whether you live in a “food desert” or work in a toxic office environment, you’ll walk away with practical strategies to take control of what you can and create a micro-environment that actually supports your goals.

Discussed on the episode:

• Why willpower works great for 4-6 weeks, then crashes spectacularly.
• The sneaky reason people on GLP-1s should detox their environment now (before it’s too late)
• The three-step detective process for identifying what’s quietly sabotaging you
• How removing your phone charger from the bedroom could transform your sleep
• The two-column social mapping exercise that reveals who’s really supporting your goals

Going vegan for weight loss? You might be in for a surprise. Despite what social media influencers claim, switching to a plant-based diet doesn’t guarantee the pounds will melt away. In fact, many vegans struggle with weight gain even when they think they’re eating healthy.

The truth is, whether you’re eating steak or tofu, the same principles of weight management still apply. You can absolutely lose weight and thrive on a vegan diet, but it requires the same intentionality, planning, and understanding of nutrition fundamentals as any other approach. The good news? It’s never been easier to succeed as a plant-based eater when you know what to focus on.

Join Holly and Jim as they sit down with Dr. Daphne Bascom, Chief Operating Officer of The Vegan Gym and an MD/PhD who brings a refreshingly balanced perspective to plant-based nutrition. Daphne shares why she became vegan later in life, busts common myths about vegan diets and weight loss, and reveals the surprising similarities between coaching vegans and omnivores. You’ll discover practical strategies for managing weight on a plant-based diet, learn which “healthy” vegan foods might be sabotaging your goals, and find out why mindset matters just as much as what’s on your plate.

Discussed on the episode:

• The biggest myth about vegan diets that keeps people stuck and gaining weight
• Why being vegan doesn’t make you “impervious to chronic disease.”
• The surprising food Daphne keeps in her purse when traveling (and why you might want to try it)
• How to navigate restaurants, airports, and social situations without derailing your goals
• The one non-negotiable supplement every vegan needs to take
• Whether plant-based proteins are really inferior for building muscle and recovery
• The “Oreo vegan” trap and how to avoid ultra-processed plant-based foods
• Why nuts might be sabotaging your weight loss (even though they’re healthy)
• The energy density principle that works whether you’re vegan or not
• How the anabolic window for protein has evolved (it’s longer than you think)

The GLP-1 medications transforming weight loss didn’t appear overnight. They’re the result of decades of groundbreaking research that fundamentally changed how we understand appetite and obesity. But how did scientists first discover that this hormone could help people lose weight? And what does this history mean for anyone using these medications today?

Join Holly and Jim as they sit down with Dr. Arne Astrup, one of the pioneering researchers who helped uncover GLP-1’s role in appetite regulation back in the 1990s. Dr. Astrup has spent over three decades at the forefront of obesity research at the University of Copenhagen and the Novo Nordisk Foundation. In this fascinating conversation, he takes us back to when obesity was still seen as a willpower problem, reveals the serendipitous collaboration that led to discovering GLP-1’s satiety effects, and shares critical insights about using these medications safely and effectively.

Whether you’re currently using GLP-1 medications, considering them, or simply curious about the science, this episode offers essential perspective from someone who’s witnessed the entire journey from early physiology experiments to today’s real-world treatments. You’ll discover why lifestyle still matters in the era of highly effective medications, and walk away with a deeper understanding of both the promise and the limitations of these groundbreaking drugs.

Discussed on the episode:

• The surprising mindset shift in the 1990s that changed how medicine views obesity
• Why a diabetes researcher and an appetite scientist became unlikely collaborators
• The first human experiment that proved GLP-1 reduces hunger (and the lunch buffet that made it possible)
• Why GLP-1 medications are so much “cleaner” than previous weight loss drugs
• The protein malnutrition risk that doctors aren’t talking about enough.
• Why half of patients stop taking these medications within months, and what that means
• The one combination that could let you reduce or stop GLP-1s without regaining weight
• Why calling these medications “the easy way out” completely misses the point
• What a leading researcher wants to accomplish after decades of groundbreaking work

Food noise. If you’ve heard the term, you probably know exactly what it means. If you haven’t, you might be about to have a lightbulb moment. It’s that relentless mental chatter about food, not hunger, not cravings, but constant, unwanted thoughts that just won’t quit.

For years, people struggling with this phenomenon didn’t even have words for it. They thought it was a willpower problem. It wasn’t. And now, thanks to groundbreaking research, we finally have a way to understand, measure, and potentially treat this invisible burden that affects people across the weight spectrum.

Join Holly and Jim as they sit down with Dr. Emily Dhurandhar, Director of Research Special Projects at Texas Tech University Health Sciences Center, and lead author of the RAID-FN Inventory, the first validated tool to measure food noise. Discover why patients, not clinicians, coined this term, how GLP-1 medications are revealing what many have silently endured, and what the future holds for treating this pervasive issue.

Discussed on the episode:

• Why food noise is completely different from normal thoughts about food
• The surprising discovery about who experiences food noise (hint: it’s not just people with obesity)
• What turning off a kitchen fan has to do with understanding these medications
• How bodybuilders and endurance athletes might experience food noise differently
• Why your environment in the 1940s versus today changes everything
• The one word clinicians need to stop assuming about food noise
• What to do if you think you’re experiencing this, but your doctor has never heard of it

For decades, people with obesity were told the solution was simple: eat less, move more, try harder. When that didn’t work, they were blamed. But science has always told a different story: obesity is a chronic, biologically driven disease, just like diabetes or hypertension. And right now, we’re witnessing the most significant transformation in obesity medicine that has ever happened.

The new GLP-1 medications like Wegovy and Zepbound are making headlines everywhere, but with breakthrough treatments come big questions. Who should take them? How do you know which one is right for you? What happens when you stop? And with millions of people getting these medications online or from providers with little expertise, how do you ensure you’re getting safe, effective care?

Join Holly and Jim as they sit down with Dr. Louis Aronne, one of the true pioneers who shaped this revolution from the very beginning. For over 30 years, Dr. Aronne has been on the front lines, treating patients and conducting research at one of the premier obesity centers in the country. He’ll share the real story behind these medications, what he’s learned from treating 9,000 patients, and where obesity treatment is heading next.

Discussed on the episode:

• The mouse experiment from the 1980s that changed everything about how we understand weight
• Why some people feel amazing on Wegovy while others do better on Zepbound
• The creative dosing strategies that help patients who can’t tolerate standard doses
• What happens to the majority of people who stop taking GLP-1 medications
• The surprising parallel between treating obesity and treating high blood pressure
• Why registered dietitians could be the perfect providers for obesity care
• The 15 new medications coming in the next five years that will transform access
• How these medications prevent 94% of diabetes cases in people with prediabetes
• The simple eating strategy that works almost like taking medicine
• What it really means when people say taking medication is cheating

You’ve done it. You’ve lost the weight. But then something shifts. The hunger gets louder. Food becomes more tempting. The scale starts creeping back up. You’re doing everything right, yet your body seems to be fighting you at every turn. If this sounds familiar, you’re not alone, and more importantly, it’s not your fault.

The truth is, after weight loss, your body launches a powerful biological response designed to bring that weight back. It’s not about willpower or discipline. It’s about survival mechanisms that were built for a world without grocery stores on every corner. Understanding what’s actually happening inside your body after weight loss changes everything from how you approach maintenance to how you talk to yourself when things get hard.

Join Holly and Jim as they sit down with Dr. Paul MacLean, one of the world’s leading experts on the biology of weight regain. You’ll discover why keeping weight off requires completely different strategies than losing it, what your metabolism is really doing after weight loss, and the science-backed tools that can help you succeed long-term despite your biology working against you.

Discussed on the episode:

• The powerful rubber band analogy that explains why your body fights to regain weight
• What’s really happening at the cellular level when you lose weight (and why it persists)
• Why the speed of weight loss may matter less than you think
• The controversial truth about whether metabolic adaptation ever goes away
• One scientist’s personal journey with weight struggle and GLP-1 medications
• The myth about starting with a “clean slate” after weight loss

You’ve heard it everywhere: “You can’t outrun a bad diet.” Or maybe it’s “Exercise doesn’t matter for weight loss.” Or wait, is it “Just lift weights and you’ll be fine”? The conflicting advice is enough to make anyone throw their hands up in frustration. What if the real answer isn’t choosing between diet and exercise, but understanding how they work together?

Join Holly and Jim as they sit down with Robert Ross, one of the rare researchers who has spent over three decades studying both sides of the equation. Ross is a professor in the School of Kinesiology and Health Studies at Queen’s University in Ontario, Canada, and he’s led groundbreaking research on how exercise, diet, and body fat interact, especially that stubborn visceral fat that drives metabolic disease. His work has shaped clinical guidelines and challenged long-held assumptions about weight loss. You’ll discover why the bathroom scale might be lying to you, what your belt buckle reveals that the scale doesn’t, and why being a “non-responder” to exercise might be a myth.

Get ready for a conversation that will fundamentally change how you think about managing your weight, whether you’re considering GLP-1 medications, struggling to keep weight off, or just trying to figure out if you should be doing cardio or lifting weights.

Discussed on the episode:

• Why the bathroom scale has done more harm than good in obesity management
• The belt buckle test that reveals more than any scale ever could
• What happens to visceral fat when you exercise without losing weight
• The truth about exercise “compensation”: Do you really eat more when you work out?
• Why 5% weight loss being “clinically meaningful” might be the wrong message.
• How cardiorespiratory fitness protects your health even if you have obesity
• The intensity question: Does working harder actually matter for fat loss?
• What we’re losing (literally) when we only focus on GLP-1 medications
• The myth of exercise “non-responders” and what the data really shows
• Why resistance exercise becomes critical as we age
• The one simple movement activity Ross recommends if you only have 10 minutes.

Writing a book isn’t just about putting words on a page. It’s about translating decades of research into something that can actually change lives. After two years of late-night rewrites, deleted chapters, and countless debates over how to explain complex science in simple terms, Holly and Jim are finally ready to pull back the curtain on their new book, Losing the Weight Loss Meds.

This episode is different. Instead of diving into weight loss science, Holly and Jim are taking you behind the scenes of their creative process. You’ll hear about the “messy middle” of writing, the chapters they rewrote twenty times, and the moment they realized this book needed to exist now. More importantly, you’ll discover why weight loss maintenance, once the “opposite of sexy,” has suddenly become the most critical challenge facing millions of people.

If you’ve ever wondered what it takes to create a science-based guide that works in real life, or if you’re curious about the future of weight management in America, this conversation will give you a front-row seat to both the struggles and the breakthroughs that shaped this groundbreaking book.

Discussed on the episode:

• The surprising moment Holly realized weight loss maintenance was finally having its day.
• Why don't half of the people stay on weight loss medications for even a year
• The three profiles that help you identify which strategies you need most
• The framework that turns scientific principles into plays you can actually use
• What happens to our country if we win (or lose) the weight maintenance game
• The vulnerable truth about putting your life’s work out into a noisy world

Ever wonder why you lose weight everywhere except where you actually want to? Or why your body seems to have "favorite spots" for storing fat? It's not in your head, and it's not random.

Join Holly and Jim as they sit down with Dr. Mike Jensen, one of the world's leading experts on body fat distribution from the Mayo Clinic. His groundbreaking research has revolutionized how doctors understand fat, revealing that where your body stores it matters just as much as how much you have. You'll discover why some fat depots are actually protective while others signal metabolic trouble, and most surprisingly, what you can actually do about it.

This conversation will change how you think about your body. From the simple "pinch test" that reveals your visceral fat status to the unexpected truth about hip and thigh fat being beneficial, Dr. Jensen shares insights that could transform your approach to weight management and metabolic health.

Discussed on the episode:

• The surprising reason why having fat on your hips and thighs is actually good for your health
• A simple at-home test to determine if you have dangerous visceral fat (hint: it involves pinching)
