Two Percent with Michael Easter – Details, episodes & analysis

The 130th Boston Marathon is this Monday. To mark the occasion, Michael sits down with Brady Holmer — a science writer, runner, and 2:24 Boston finisher — to go deep on what the race actually feels like, why super shoes might be saving you 5-8 minutes, how to fuel a marathon without your gut exploding, and whether anyone can qualify for Boston.

Then Dr. Mike Roussell, a PhD nutritionist from Penn State who works with NBA players and busy execs, breaks down the ultraprocessed food debate that's tearing through the nutrition world. Are ultraprocessed foods actually evil? Or are they sometimes the healthiest option? He walks through a mind-blowing ultraprocessed food study, why fiber is the most underrated nutrient, and a practical framework for using UPF without letting it wreck your diet. Plus his surprisingly nuanced take on GLP-1 drugs.

After that, Michael heads to the Two Percent Kitchen with the most ridiculous endurance recipe you've ever seen.

In this episode of Two Percent, Michael sits down with backcountry bow hunter and filmmaker Donnie Vincent to unpack what months in remote wilderness teach you about stress, calm, and competence. Donnie was featured heavily in Michael’s bestselling book, The Comfort Crisis, and now he joins Michael for the first time on mic since the book’s release.

They talk about the ethics and emotional reality of hunting, why sourcing your own food changes your relationship with life, and how modern convenience hijacks the ancient “search” that once made humans thrive. Donnie shares stories from Alaska—about storms, solitude, and the kind of discomfort that forces growth.

The two discuss the importance of building resilience when nothing's certain, staying present in wild places, and how you can get the same benefits of a hunt without ever picking up a bow – all it takes is choosing experiences that are hard and honest.

Walking shaped humans into who we are—and it’s one of the simplest ways to improve health, mood, and longevity right now. In this episode of Two Percent, Michael sits down with evolutionary geneticist Dr. Melissa Ilardo and writer Foster Kamer to explore what endurance science says about how far humans can actually go, why the brain often quits before the body, and how small daily choices compound into massive long-term outcomes.

We cover the real research behind step counts (including why the 10,000 number is a myth), the minimum effective dose that meaningfully improves health, and how to make walking effortless by stacking it into things you already do. Plus: persistence hunting, sleep differences that change performance, and what ultra-endurance reveals about mindset.

Melissa Urban — founder of Whole 30 and author of The Whole30 (updated 2024) and The Book of Boundaries — sits down with Michael Easter for one of the most honest conversations on this feed yet. Two sober people (Michael 10+ years, Melissa 24+ years) unpack the parallels between drug addiction and food behavior, why the first time Melissa went to rehab didn't stick, and the single question that rewired every habit in her life: "What would a healthy person with healthy habits do?"

They dig into the science of elimination diets, the 17 years of data behind Whole 30, why Melissa publicly reversed her position on seed oils in 2024, how food becomes the fastest socially acceptable distraction from our feelings, and why you can white-knuckle any elimination program and end up exactly where you started. Plus: integrity over followers, mountains as church, and why "does this feel gross?" is the best business rubric Melissa's ever used.

Everyone has a vice. Drinking, smoking, social media, diet soda. And the modern wellness internet will tell you that if you want to live a long, healthy life, you need to cut every single one of them out. But is that actually true?

In this episode of Two Percent, we take a nuanced look at vices and whether some of them might actually enhance your life when you use them the right way. We don't have to live like monks to live a good life.

First up is Dean Stattmann, a GQ reporter who spent three months sober and wrote a now-viral piece titled "Why My 2026 Resolution Is to Start Drinking Again." His Whoop scores got better, but his friendships, his marriage, and his mood got worse. Dean explains what alcohol actually does for human connection, what anthropologists call "costly signaling," and why moderate drinking might not be the villain the internet has made it out to be.

Then Taylor Lorenz, author of Extremely Online and host of the Power User podcast, joins to argue something that sounds heretical in 2026: social media is not addictive. We break down the real science on dopamine (spoiler: it's probably cortisol), the recent California Meta verdict, Section 230, KOSA, looksmaxing, Clavicular's overdose, and what's actually driving the teen mental health conversation.

Finally, Michael opens up about his own personal vice, a five-a-day habit, and explains why the science on aspartame, cancer, and the gut microbiome isn't nearly as scary as the internet would have you believe.

What if everything you believe about freedom is wrong?

Author David Epstein joins Michael Easter to break down why constraints — not freedom — drive better work, better wellness, and better creativity. Epstein is the bestselling author of Range and The Sports Gene, and his new book Inside the Box: How Constraints Make Us Better argues we have it backwards on freedom.

They discuss why General Magic collapsed under unlimited possibility while Pixar dominated, why your brain is literally built to prevent you from thinking, and the simple sleep hack that made David a morning person for two years without an alarm clock.

This is the playbook for thinking slow, acting fast, and finally figuring out what to stop doing.

A 3-year old beat a PhD engineer at an engineering problem while playing legos—and that single moment kicked off a decade of research that exposed one of the strongest, most underrated biases in the human brain: we almost never subtract.

This week, Michael sits down with Dr. Leidy Klotz — University of Virginia engineering professor, former pro soccer player, and author of Subtract, which explored why your brain defaults to adding when removing is the better answer.

His new book In a Good Place, unpacks why open offices steal your focus, the science of the “home field advantage” and why the spaces you live in might be quietly running your life (and even affecting  your lifespan).

More than 100,000 Americans die of drug overdose every year. The solution—or at least part of it—might be dorky as hell.

Sam Quinones spent 12 years reporting on America’s drug crisis and how — heroin, fentanyl, meth have reshaped the country. In this episode, l he unpacks how Mexican cartels replaced poppy fields with chemicals, lowered the price of meth by 90%, and unintentionally created a schizophrenia crisis. Since then, Sam has been on a mission to find the antidote to modern day addiction. And he found it in an unlikely source: the tuba. yes, the musical instrument. Sam explains why marching band may very well be the best anti-drug program in America and how we can help our children avoid a life of addiction and suffering.

Even if you have no interest in playing the tuba, the lessons from marching band can help anyone build a better life. This episode is about the value of hard work without fanfare, the power of community, and how to find hope in a broken world.

Sam is the author of Dreamland, The Least of Us, and his new book The Perfect Tuba: Forging Fulfillment from the Bass Horn, Band, and Hard Work.

Is work supposed to feel this miserable? In this episode, Michael Easter sits down with two people who answer the question from opposite ends of the spectrum: one who found deep fulfillment inside the system, and one who walked away from it entirely.

First, Dr. Mim Ari, an internist and associate professor at the University of Chicago, breaks down what it actually means to be a "deeply fulfilled workist." She explains why we anchor on the negatives, the 10:1 positive ratio that should reframe your day, how AI scribes are quietly changing medicine, and why intrinsic motivation beats external validation every time.

Then, Robin Greenfield, who once aimed to be a millionaire by 30, talks about why he gave it all up. He shares the moment he realized the American Dream was "the world's nightmare," his 100-change checklist for breaking free of consumerism, what it was like to walk NYC in a 135-pound trash suit, and the three months he spent owning literally nothing in Griffith Park.

Michael closes with the very first 2% AMA, including the one phone hack that has saved his work-life balance, the truth about exercise recovery, an update to The Comfort Crisis on autophagy, and the inaugural "Department of Dipshit Questions."
