104: How GLP-1s Are Impacting Women’s Health: Fertility, Thyroid, Menopause & Muscle | Live SXSW Panel
Épisode 104
jeudi 22 octobre 2026 • Durée 01:15:02
GLP-1 medications have become synonymous with weight loss—but what if their impact on women’s health goes far beyond the number on the scale?
Recorded live at SXSW in Austin, this special panel brings together experts in thyroid and metabolic health, fertility, menopause, and strength training to explore what women should really understand about GLP-1 medications.
Moderated by Dr. Shannon Ritchey, PT, DPT, the conversation features McCall McPherson, PA-C, Dr. Natalie Crawford, MD, and Dr. Jessica Shepherd, MD. Together, they discuss appropriate use, microdosing, insulin resistance, inflammation, thyroid disease, PCOS, fertility, perimenopause, menopause, muscle preservation, side effects, long-term use, and the importance of individualized care.
🔑 In This Episode:
What GLP-1 medications actually do beyond appetite suppression
Why these medications were first used for diabetes and metabolic health
Microdosing vs. traditional dosing
Why individualized dosing may help some women better tolerate treatment
GLP-1s, thyroid dysfunction, Hashimoto’s, and inflammation
Separating thyroid-cancer concerns from what the panel says current human evidence shows
Why adequate calories and protein matter while using a GLP-1
The importance of preserving and building muscle
GLP-1s, insulin resistance, PCOS, and fertility
Why GLP-1 medications are not recommended while actively trying to conceive or during pregnancy
Perimenopause, menopause, HRT, glucose regulation, and visceral fat
When GLP-1 use may be short-term vs. longer-term
Semaglutide, tirzepatide, and individualized prescribing
DEXA scans, creatine, resistance training, and lean-mass preservation
Fasting insulin, A1c, leptin, and other metabolic markers
Sleep, HRV, hydration, and what wearables may reveal
Food noise, body image, and why appropriate medical screening matters
Fertility, PCOS & GLP-1s
Dr. Natalie Crawford explains that fertility is more than simply the ability to become pregnant—it can also reflect hormonal and metabolic health.
For patients with PCOS and insulin resistance, improving metabolic health may help restore ovulation and support fertility. However, Dr. Crawford emphasizes that GLP-1 medications are not intended to be used while actively trying to conceive or during pregnancy and discusses stopping them before conception under medical guidance.
She also highlights resistance training and skeletal muscle as powerful tools for glucose utilization, insulin sensitivity, inflammation, and reproductive health.
Thyroid Health, Inflammation & Microdosing
McCall shares how her approach evolved toward lower, individualized doses after seeing patients struggle with nausea, inadequate nutrition, and difficulty consuming enough protein on standard dosing.
The goal, she explains, is not simply appetite suppression or rapid weight loss. It is finding a dose that allows patients to nourish themselves, preserve muscle, and improve metabolic health while minimizing side effects.
Menopause & Midlife Metabolic Health
Dr. Jessica Shepherd explores how declining estrogen, progesterone, and testosterone during perimenopause and menopause influence the entire body—not just reproductive health.
The panel discusses the relationship between hormone changes, glucose regulation, insulin, inflammation, visceral fat, joint symptoms, and the potential role GLP-1s may have alongside other individualized midlife interventions.
Protecting Muscle on a GLP-1
Dr. Shannon Ritchey emphasizes that simply “lifting weights” is not always enough to preserve or build muscle.
The panel discusses adequate protein and calories, monitoring body composition, potentially using tools such as DEXA scans, and performing resistance training with enough intensity to stimulate muscle adaptation.

Épisode 102
jeudi 8 octobre 2026 • Durée 47:42
What if the brain fog, forgetfulness, emotional overwhelm, anxiety, or difficulty getting things done isn’t simply stress—or even your thyroid?
In this episode of Modern Thyroid & Wellness, McCall McPherson, PA-C sits down with Dr. Jolene Brighten, women’s health expert and bestselling author, to explore the often-overlooked connection between ADHD in women, thyroid function, hormones, perimenopause, inflammation, and brain health.
Dr. Brighten explains why so many women reach adulthood without an ADHD diagnosis and why hormonal transitions can suddenly make symptoms that were once manageable feel impossible to ignore.
She also explains an important overlap for thyroid patients: hypothyroidism itself can create ADHD-like symptoms, including brain fog, low mental energy, working-memory problems, changes in neurotransmitter function, and difficulty with executive function.

101: From PCOS & Hypothyroidism to Long COVID: Personalized Healing, Peptides & Regenerative Medicine with Nicole Peterson Doran
Épisode 101
jeudi 1 octobre 2026 • Durée 38:45
What happens when you’re doing everything “right” for your health but still don’t feel like yourself?
In this episode of Modern Thyroid & Wellness, McCall McPherson sits down with Nicole Peterson Doran, co-founder of PUR-FORM, Humanaut Health franchisee, and host of The Healthspan Collective Podcast, to talk about her decades-long journey through PCOS, hypothyroidism, inflammation, fertility concerns, long COVID, mast cell activation symptoms, and ultimately finding a more personalized approach to health.
Nicole’s story began at just 16 years old when she rapidly gained weight, developed facial hair, experienced irregular periods, severe fatigue, and intense brain fog. She was diagnosed with PCOS and later hypothyroidism, but traditional treatment did little to resolve how she actually felt.
That experience eventually led her into integrative medicine, whole-food nutrition, mindfulness, and the concept of bio-individuality—the idea that what works for one person may not work for another.
In This Episode:
Nicole’s experience with PCOS and hypothyroidism beginning in her teens
Why whole foods and lifestyle changes became a turning point
The importance of bio-individuality in thyroid and hormone health
Why there is no single “best” diet, medication, or wellness plan for everyone

98: Thyroid Dysfunction, Cellular Stress & Autophagy: A New Way to Think About Chronic Illness with Dr. Bill Rawls
Épisode 98
jeudi 10 septembre 2026 • Durée 01:06:18
What if thyroid dysfunction isn’t always an isolated thyroid problem, but a signal that the cells throughout your body are under too much stress?
In this episode of Modern Thyroid & Wellness, McCall McPherson sits down with Dr. Bill Rawls, physician, bestselling author, and co-founder of Vital Plan, for a fascinating conversation about cellular health, chronic illness, autophagy, microbes, stress, thyroid function, and the role herbs may play in supporting resilience.
Dr. Rawls’ perspective grew out of his own health crisis. After years of intense work and inadequate sleep as an OB-GYN, his health deteriorated dramatically. He experienced fatigue, neurological symptoms, joint problems, cardiac symptoms, and eventually discovered evidence of Lyme disease. After conventional approaches failed to restore his health, his experience with herbal therapy led him into decades of research on chronic illness and cellular wellness.
In This Episode, You’ll Learn:
Why Dr. Rawls views cellular stress as a common thread in chronic illness
Five major categories that can stress our cells
Why nutrition, environmental toxins, sleep, movement, and microbes matter
What autophagy is and why cellular repair is essential
How fasting, exercise, and stress can influence autophagy
The relationship between thyroid hormone and cellular metabolism
Why Dr. Rawls views thyroid dysfunction as a possible signal of broader cellular stress
His hypothesis about microbes, thyroid cells, and Hashimoto’s
How chronic psychological stress and cortisol affect cellular recovery
Why whole foods, plant diversity, sleep, movement, and reducing toxic exposures form the foundation of his approach
How adaptogenic herbs may support cellular resilience

With thousands of supplements promising more energy, better hair, improved thyroid function, and healthier aging, how do you know what your body actually needs?
In this episode of Modern Thyroid & Wellness, McCall McPherson sits down with Melissa “Mel” Afflerbach, Clinical Director of Weight Loss & Supplement Programs, for a practical conversation about the supplements they use and recommend within their thyroid and metabolic health programs.
They break down some of the most common concerns women with hypothyroidism and Hashimoto’s experience—from persistent fatigue and low energy to hair loss—and explain why supplementation should support the bigger picture rather than replace investigating the root cause of a symptom.
In This Episode, You’ll Learn:
Why correcting thyroid function may not completely resolve fatigue
How adrenal and mitochondrial health relate to energy production
The difference between stimulant energy and supporting cellular energy
Why thyroid dysfunction can contribute to hair shedding and changes in hair, skin, and nails
Why ferritin and thyroid labs matter when investigating hair loss

96: Your Thyroid Is a Barometer: What Chronic Disease Can Teach Us About Stress, Environment, and Prevention with Kelly McKenna
Épisode 96
jeudi 27 août 2026 • Durée 31:23
What if your thyroid symptoms aren’t an isolated problem, but one signal from a body asking you to pay attention?
In this episode of Modern Thyroid & Wellness, McCall McPherson sits down with Kelly McKenna, CEO and Co-Founder of End Chronic Disease, to explore thyroid health, autoimmunity, chronic stress, environmental exposures, nutrition, and what it really means to focus on prevention.
Kelly’s health journey began with a celiac disease diagnosis in high school, followed by nearly two decades of autoimmune and chronic health challenges. In her early 30s, thyroid labs disrupted her plans to freeze her eggs and pushed her to ask a different question: instead of accepting hypothyroidism as inevitable, what might actually be driving it?
That curiosity eventually changed both her health and career.
Key Topics Covered
Kelly’s experience with celiac disease, hypothyroidism, and Hashimoto’s
How childhood stress may influence long-term health
Why sleep, nutrition, movement, relationships, and environment matter
Environmental exposures and thyroid health
The conversation around paraquat and chronic disease
Why prevention should begin in childhood
Iodine, selenium, vitamin D, iron, and thyroid health
Why Kelly calls her thyroid a “barometer” for her whole body
Simple strategies for fatigue and autoimmune flares
The importance of boundaries and emotional health
Bringing preventive health education into schools
Why chronic disease prevention requires both individual and systemic change
When Your Thyroid Becomes a Warning System
After being re-diagnosed with Hashimoto’s, Kelly began closely observing how changes in sleep, nutrition, nutrient status, stress, and other aspects of daily life corresponded with her symptoms and thyroid labs.
She focused on nutrients including iodine, selenium, vitamin D, and iron and experimented with dietary changes. As her thyroid markers improved, she noticed changes in her skin, digestion, fatigue, and overall wellbeing too.
95: Your DNA Is Not Your Destiny: How Genetics Can Personalize Thyroid Health, Hormones, Metabolism, and Longevity with Kashif Khan
Épisode 95
jeudi 20 août 2026 • Durée 39:31
What if the foods, supplements, workouts, and hormone therapies that work beautifully for someone else are completely wrong for your biology?
In this episode of Modern Thyroid & Wellness, McCall McPherson sits down with Kashif Khan, bestselling author of The DNA Way, celebrity longevity coach, and two-time TEDx speaker, for a deep dive into functional genomics and personalized health. Kashif explains how DNA acts as an instruction manual for the body and why understanding those instructions may help explain why people respond so differently to the same foods, environmental exposures, exercise programs, supplements, and hormone therapies.
Drawing from his own experience with chronic illness and years of genetic research, Kashif explores the relationship between genetics and lifestyle, including thyroid health, Hashimoto’s, women’s hormones, detoxification, metabolism, gut health, sleep, cognitive function, inflammation, and longevity. The conversation offers a different way to think about personalized medicine: instead of simply asking what disease you may be genetically predisposed to, ask how your biology works and what choices may better support it.
Key Topics Covered
What DNA actually tells us about everyday health
Why genetics are not necessarily destiny
Genetics versus epigenetics
How lifestyle, environment, and nutrition interact with genetic predispositions
Kashif’s personal journey from chronic illness to genetic research
Why two people can make the same health choices and experience very different outcomes
Genetic differences in detoxification
Why DNA testing is different from repeatedly testing hormones, cholesterol, or the microbiome
How genetics may influence sleep and circadian preferences
Personalizing nutrition and carbohydrate intake
Genetics, metabolism, and gut health
Environmental exposures and individual detoxification capacity
Women’s hormone health and estrogen metabolism
Genetics, Hashimoto’s, autoimmunity, and thyroid health
Reducing refined carbohydrates
Pairing carbohydrates with protein and fat
Using continuous glucose monitors to better understand personal responses
Strategic intermittent fasting when appropriate
💊 Medications Discussed
Metformin
Improves insulin sensitivity
Has a long history of clinical use
Can be a cost-effective early intervention
GLP-1 receptor agonists
Reduce appetite and slow gastric emptying
Lower liver glucose production
Improve insulin signaling
May help reduce inflammation in appropriate patients
🌿 Key Takeaways
Insulin resistance can often be improved when identified early.
“Normal” lab values do not always tell the entire story, and weight gain is far more complex than calories in versus calories out.
One of the biggest themes in this episode is that inflammation connects metabolic dysfunction, thyroid disease, and autoimmunity, making individualized, whole-body evaluation incredibly important.

Dr. Brighten explains that hypothyroidism can affect brain energy, memory, attention, neurotransmitters, and executive function. Her approach is to address hypothyroidism first when it could be contributing to new ADHD-like symptoms.
If difficulties with planning, organization, emotional regulation, focus, or executive function persist—especially when similar patterns have existed since childhood—it may be worth investigating another layer.
Why Hormones Matter
Dr. Brighten discusses important hormonal windows when ADHD symptoms may change or become more obvious: puberty, postpartum, the pill, perimenopause, and postmenopause.
During perimenopause in particular, shifts in estrogen, progesterone, testosterone, cortisol, insulin regulation, mitochondrial function, and brain energy may make brain fog, sleep problems, emotional dysregulation, and executive dysfunction more difficult.
📖 AVAILABLE NOW: ADHD and Women
Dr. Brighten’s new book, ADHD and Women: A Guide to Optimizing Your Hormones and Thriving with ADHD, is available now.
The book explores female ADHD through a hormone-focused lens and includes guidance on gut health, sleep, exercise, nutrition, supplements, hormones, quizzes, and a 14-day reset.
This episode is for educational and informational purposes only and is not intended to diagnose, treat, cure, or prevent disease or replace individualized medical care.
When she decided she wanted to conceive, she worked intentionally with her practitioners, focused on reducing inflammation, prioritized rest, limited travel, reduced alcohol and sugar, and used supplements including CoQ10 and fish oil.
She became pregnant after approximately three months, while emphasizing that fertility is deeply individual and there is still an element of uncertainty that cannot always be controlled.
Long COVID, MCAS & Finding New Tools
After COVID, Nicole experienced months of intense histamine-type symptoms, inflammation, brain fog, irritability, and weight changes.
She describes working with practitioners and personally using several tools during her recovery, including microdosed tirzepatide, thymosin alpha-1, larazotide, nutritional support, and regenerative therapies. These are shared as Nicole’s personal experience and are not recommendations for every listener.

Dr. Rawls encourages listeners to zoom out from individual diagnoses and look at the health of the cells themselves.
He organizes common sources of cellular stress into five broad areas: inadequate nutrition, toxic exposures, insufficient recovery and sleep, physical stress or inactivity, and microbes.
His goal is not simply to suppress symptoms, but to create an internal environment that gives cells the resources and recovery time they need to function well.
Autophagy: Your Cells’ Recycling and Repair System
A major part of the conversation focuses on autophagy, the ongoing process cells use to recycle damaged components and maintain themselves.
Dr. Rawls explains how fasting, movement, and other mild stressors may stimulate this process, while excessive stress can become counterproductive. He emphasizes balance between stress and recovery, rather than believing that more fasting or harder exercise is always better.
What Does This Mean for Thyroid Health?
Dr. Rawls describes thyroid hormone as an important metabolic signal that helps cells produce and use energy.
His central argument is that when cells are chronically stressed, thyroid function may become part of that larger picture. Rather than viewing fatigue or thyroid dysfunction completely in isolation, he encourages looking at sleep, nutrition, stress, environmental exposures, movement, and overall cellular health.
Dr. Rawls also shares RESTORE180, Vital Plan’s six-month program for people navigating complex chronic illness. The program progresses through stress regulation, gut and detoxification support, and concentrated botanical formulations.
The MDRN Wellness store was created to make choosing supplements less overwhelming. Products are selected by McCall and the clinical team with the needs of people navigating thyroid dysfunction, hormone concerns, low energy, and related symptoms in mind.
Today, Kelly describes her thyroid as a “barometer for my whole body.” When fatigue and familiar symptoms return, she views them as signals that her body may need more support, rest, or recovery.
Stress, Environment, and Chronic Disease
Kelly also shares how growing up with a brother who experienced significant disabilities and frequent seizures created a chronic sense of uncertainty and stress, even within a loving family. Only later did she recognize how those experiences may have shaped her stress response.
The conversation expands into environmental health, including paraquat exposure, ultra-processed foods, school environments, movement, and why the places where we live, work, learn, and eat deserve a larger role in conversations about chronic disease prevention.
What If You’re Already Exhausted?
When someone is already depleted, complicated wellness routines can feel impossible.
Kelly recommends returning to basics. Her personal recovery toolbox has included restorative yoga, putting her legs up the wall, prioritizing sleep, simplifying food, gentle walking, acupuncture, positive experiences with people she loves, and examining emotional stress or boundaries that may be draining energy.
The goal is to learn your body’s signals and build a collection of tools you can return to when you need them.

Why understanding the biology underneath symptoms matters
DNA as Your Body’s Instruction Manual
Kashif describes DNA in practical terms as an instruction manual contained within the cells of the body.
Genes provide instructions for countless biological processes, including producing hormones, metabolizing food, detoxifying compounds, and supporting cognitive function.
The important difference is that everyone's instruction manual is slightly different.
That helps explain why two people can follow the same diet, take the same hormone prescription, or perform the same exercise routine and experience dramatically different outcomes.
Genetics Load the Gun, Environment Pulls the Trigger
One of the central ideas in the episode is the interaction between genetics and epigenetics.
Your DNA does not change every time you change your diet or lifestyle, but the choices you make interact with the biological instructions you inherited.
Kashif groups those choices into three broad areas:
Environment
Nutrition
Lifestyle
Environment includes what you are exposed to. Nutrition includes food, supplements, and other nutritional interventions. Lifestyle encompasses factors such as exercise, work, and sleep.
Understanding genetics, therefore, is not simply about predicting disease. Kashif sees it as a way to understand how your individual body processes the choices you make every day.
Kashif’s Personal Health Journey
Kashif did not enter genomics through a traditional medical or scientific career path.
Around age 38, after previously considering himself healthy, he developed multiple chronic health problems, including severe eczema, psoriasis, gut issues, migraines, reflux, and inflammation.
He received diagnoses and prescriptions but remained focused on a different question:
Why did this happen?
His search took him through traditional Chinese medicine, homeopathy, naturopathy, functional medicine, hormone health, the microbiome, and eventually genetics.
Understanding genetic differences helped him begin connecting his individual biology with environmental and lifestyle exposures. His recovery ultimately inspired him to leave his previous technology consulting business and build a genetic research company.
Why Your Detoxification Genetics Matter
Kashif uses his own GSTM1 genetics as an example of how individual differences can influence detoxification.
He explains that glutathione plays an important role in neutralizing and removing unwanted compounds and that genetic differences can affect how those processes function in different areas of the body.
In Kashif’s case, he discovered a copy number variation involving GSTM1, which became one piece of understanding why exposures that did not seem to affect someone living an otherwise similar lifestyle could affect him differently.
This illustrates the broader problem with one-size-fits-all wellness advice: what is tolerated well by most people may not necessarily be optimal for every individual.
Why DNA Testing Is Different
Hormones change.
The gut microbiome changes.
Toxic burden changes.
Cholesterol changes.
DNA does not.
Kashif explains that this permanence is part of what makes genomic information valuable. Rather than repeatedly testing DNA, the goal is to understand what your genetic information means and then use that knowledge alongside changing health data throughout your life.
His current mission centers heavily on education and helping people better understand their own genetic information.
Start With the Foundation Before Biohacking
One of Kashif’s cautions is that people often enter the longevity and biohacking world by copying people who have already spent years optimizing their health.
That can quickly become overwhelming.
His suggested framework begins with identifying where you currently are.
If there is an acute health problem, address that first.
Then consider foundational areas such as:
Nervous system regulation
Gut health
Toxic burden
Health optimization
Longevity and advanced biohacking
Trying to fix decades of accumulated problems in two weeks is unlikely to create the sustainable outcome people are looking for.
The goal is to work in the right order rather than doing everything at once.
Five Areas Functional Genomics Can Help Personalize
Kashif identifies several major areas where he believes functional genomics can provide useful insights.
Cognitive Function
Genetic differences may influence neurochemical pathways involved in behavior, reward, focus, and how people perceive and respond to their environment.
Sleep
Difficulty falling asleep, staying asleep, feeling restored, or naturally functioning better earlier or later in the day may involve different biological pathways.
Metabolism
People do not necessarily respond identically to the same macronutrient balance.
Kashif shares an example involving female athletes who were struggling on a low-carbohydrate approach but performed better after carbohydrates were reintroduced based on their individual biology.
Gut and Environmental Health
Genetics may help provide context for how an individual responds to environmental exposures and how effectively certain detoxification processes function.
Hormones
This is one of the areas Kashif believes has enormous potential, particularly for women. Understanding how someone produces, binds, metabolizes, and clears hormones may provide a more personalized framework for women's health.
Genetics, Thyroid Health, and Hashimoto’s
McCall and Kashif take the conversation directly into thyroid health.
Kashif explains that people may arrive with symptoms such as fatigue without realizing that thyroid physiology could be part of the picture.
They discuss potential connections among detoxification pathways, environmental exposures, gut-brain signaling, autoimmunity, estrogen metabolism, and thyroid health.
The bigger takeaway is that there may not be one universal reason someone develops Hashimoto’s or another thyroid problem.
Kashif’s approach is to ask what biological pathways may be contributing in that particular individual so interventions can become more precise rather than simply adding more generalized recommendations.
Why Women’s Hormones Need More Personalization
