127. Allison Evans: Hidden Household Toxins That Are Making You Sick Jan 06, 2026

Show notes

Toxin exposure rarely announces itself loudly, yet it quietly shapes hormone balance, immune resilience, mood, and neurological health long before a diagnosis appears. The real tension lies in the fact that these exposures are largely invisible, normalized, and happening inside the very spaces meant to keep us safe.

We dive deeper into this in the Extend podcast with Allison Evans. We also chat about the "toxic bucket" concept, why synthetic fragrance and harsh disinfectants can act as endocrine disruptors and neurotoxins, how asthma, fertility challenges, and chronic symptoms can be triggered by everyday products, and where to start removing toxic load without fear or overwhelm.

126. How to Fix Your Metabolic Health at Any Age Jan 01, 2026

Show notes

Most people think they're doing "enough" for their health, yet nearly 90% of Americans are metabolically unhealthy and don't know it. In this episode, I challenge outdated metrics like BMI, explain why sleep quality matters more than hours slept, and break down what actually moves the needle when it comes to long-term health.

In this solo episode of EXTEND, I outline my five core health frameworks for 2026. I also walk through what it means to become the CEO of your own health, how to use simple biomarkers instead of guesswork, how to run personal N-of-1 experiments, and why muscle, sleep, and toxic exposure play a far bigger role in health than most people realize.

What's Discussed:

(00:00) How to Take Control of Your Health in 2026 (01:41) Becoming the CEO of Your Own Health Using Your Data (02:50) Why 90% of Americans Are Metabolically Unhealthy (07:41) Why Weight and BMI Are Misleading Health Metrics (11:40) The Key Biomarkers That Actually Matter (13:01) Why Sleep Quality Matters More Than Sleep Duration (16:09) How N-of-1 Experiments Remove Health Guesswork (18:09) The Hidden Health Impact of Everyday Toxic Exposure

125. Best of Mental Health: The Foundation of Brain and Whole Body Health Dec 30, 2025

Show notes

Mental health is shaped by how well the brain produces energy, how well the nervous system remains under stress, and how effectively the mind adapts over time. When these systems begin to break down, problems often appear years before a diagnosis, showing up as anxiety, brain fog, distraction, burnout, or emotional dysregulation that are frequently treated in isolation.

This is a special Best Of episode of Extend, where I've compiled the most important insights from conversations with leaders examining mental health through neuroscience, metabolism, nervous system regulation, and mental training, including Jay Shetty, Dr. Chris Palmer, Jim Kwik, Maya Raichoora, and Gabby Bernstein.

These selected clips highlight why mental health cannot be reduced to brain chemistry alone, how metabolic dysfunction and chronic stress quietly impair brain energy, and why nervous system safety is foundational to healing. You'll hear how focus and mental fatigue are often physiological, how visualization and mindset influence neural pathways, and why regulation, meaning, and consistency matter more than quick fixes. By pulling together these key moments, this episode reflects the patterns I see repeatedly in practice and across these expert discussions, offering a clearer framework for supporting mental health early, when intervention is most effective and long-term resilience can be built.

What We Discuss:

Jay Shetty, bestselling author and former monk, explores why mental health begins with inner alignment, how chronic stress is amplified by disconnection from values, and why vulnerability is a skill that deepens emotional resilience rather than a weakness.
Dr. Chris Palmer, Harvard-trained psychiatrist and author of Brain Energy, explains why mental illness cannot be separated from metabolic health, how impaired brain energy drives symptoms like anxiety and depression, and why addressing mitochondrial and metabolic dysfunction changes outcomes.
Jim Kwik, brain coach and author of Limitless, breaks down why brain fog, distraction, and mental fatigue are not character flaws, how modern habits drain cognitive energy, and what actually restores focus, memory, and mental clarity.
Maya Raichoora, mental fitness expert and author of Visualize, explores how visualization rewires neural pathways, why the brain responds to imagined experiences as real, and how mental training can influence both cognitive performance and physical health.
Gabby Bernstein, #1 New York Times bestselling author and podcast host, explains why nervous system safety is foundational to mental health, how emotional regulation directly affects inflammation and recovery, and why feeling safe in the body is essential for long-term resilience.

124. Best of Strength Training: Why Strength Determines How You Age Dec 25, 2025

Show notes

Over the past year on Extend, I've had powerful conversations with experts who all kept pointing back to the same foundation: strength training. So in this episode, I'm bringing together a Best Of compilation featuring key moments from Andy Galpin, Vonda Wright, JJ Virgin, Louisa Nicola, and Kelly and Juliet Starrett to highlight why strength matters far beyond the gym.

This episode explores strength training from every angle that truly impacts longevity. I break down why muscle is a metabolic engine, how bone health shapes aging decades before problems appear, and how strength and movement directly support brain health and cognitive performance. You'll also hear why mobility is a daily practice, not a workout add-on, and how small habits outside the gym often determine how strong, capable, and pain-free you stay over time.

Across these clips, the message is clear: strength training isn't about aesthetics or chasing extremes. It's about building a body and brain that can adapt, recover, and thrive for decades. Whether your goal is longevity, injury prevention, better energy, or aging with confidence, this episode brings together the most important insights to help you train smarter and move better for life.

What We Discuss:

(00:00) JJ Virgin, nutrition and fitness expert, explains why muscle is the foundation of metabolism, strength, and long-term vitality, and how protein intake and smart training support powerful aging.

(00:00) Andy Galpin, human performance scientist, breaks down how personalized training and understanding individual physiology can help you build strength more effectively and recover like a pro athlete.

(00:00) Dr. Vonda Wright, orthopedic surgeon and longevity expert, explores how strength training protects bone density, supports hormones, and reduces fracture risk as we age.

(00:00) Louisa Nicola, neurophysiologist and performance coach, connects strength and movement to brain health, explaining how exercise supports cognition, reduces inflammation, and protects against neurodegeneration.

(00:00) Kelly and Juliet Starrett, movement and mobility experts, share why daily mobility habits matter as much as workouts, and how strength, posture, and movement patterns shape longevity.

123. Best of Metabolic Health: Why Metabolic Health Changes Everything Dec 23, 2025

Show notes

Metabolic health is the foundation that determines how your body produces energy, manages inflammation, regulates hormones, and protects you from chronic disease. When it breaks down, problems show up years later, long after the real warning signs were missed.

This is a special Best Of episode of Extend, where I've compiled the most important insights from conversations with leaders in metabolic health and longevity, including Cynthia Thurlow, Ben Azadi, Dr. Mark Hyman, Casey Means, Josh Clemente, and Karan Rajan. These selected clips highlight why waiting for diabetes is far too late, how insulin resistance can quietly develop over years, and which biomarkers reveal metabolic dysfunction long before symptoms appear.

You'll hear how glucose and insulin regulation influence gut health, inflammation, muscle mass, hormone balance, and brain and skin health. By pulling together these key moments, this episode reflects the patterns I see every day in clinic and across these expert discussions, offering a clearer framework for protecting metabolic health early, when intervention has the greatest impact.

What's Discussed:

Cynthia Thurlow, nurse practitioner and metabolic health expert, explains why waiting for diabetes is far too late, how insulin resistance develops years before diagnosis, and which early biomarkers reveal true metabolic risk.
Ben Azadi, metabolic health educator and author, breaks down why type 2 diabetes is preventable and reversible, how insulin resistance can exist for over a decade without abnormal blood sugar, and why fasting insulin is one of the most important labs to track.
Dr. Mark Hyman, functional medicine physician and longevity leader, explores why insulin is rarely tested, how muscle loss accelerates metabolic decline, and why chronic disease shares common metabolic roots.
Casey Means, physician and metabolic health advocate, connects metabolic dysfunction to modern lifestyle stressors, explains the core markers of metabolic syndrome, and shares why fewer than 7 percent of Americans meet optimal metabolic criteria.
Josh Clemente, health technology innovator, discusses why continuous glucose monitoring offers real-time insight into metabolic health and how glucose regulation shapes long-term disease risk.
Karan Rajan, surgeon and gut health educator, explains how the gut microbiome influences systemic inflammation, insulin sensitivity, skin health, and metabolic stability across the entire body.

122. Dr. Mayim Bialik on Stress, Mental Health, and Human Connection Dec 18, 2025

Show notes

What if the stress you feel every day is not a personal failure, but a biological response to how modern life pulls at your nervous system? In this episode, I sit down with Dr. Mayim Bialik to explore why so many people feel overwhelmed, distracted, and disconnected, even when they are doing everything they were told should make them happy.

We talk about how stress lives in the body, how technology quietly rewires attention and dopamine, and why mental health cannot be separated from gut health, lifestyle, and human connection. Mayim shares her path from child actor to neuroscientist, how science and spirituality meet in real life, and why resilience is built through daily practices, not quick fixes. We also unpack trauma, attention, parenting in a digital world, and why learning to regulate your nervous system may matter more than any single intervention.

This conversation is an invitation to slow down, reconnect with yourself, and remember that healing does not start with perfection. It starts with awareness.

Dr. Mayim Bialik is a neuroscientist, actor, author, and mental health advocate. She holds a PhD in neuroscience from UCLA and is widely known for her role on The Big Bang Theory.

121. How to Protect Your Brain at Every Age Dec 16, 2025

Show notes

How much control do you actually have over how your brain ages? Most people assume memory loss and cognitive decline are inevitable, but the science tells a very different story. In this solo episode, I break down why brain health is something you can actively protect decades before symptoms ever appear.

I walk you through the core systems that shape how your brain functions over time, from blood sugar regulation and inflammation to sleep, stress, circulation, and daily movement. We explore how lifestyle signals either strengthen or slowly erode cognitive resilience, and why modern research now allows us to detect risk far earlier than ever before. I also explain the biomarkers I watch, the habits that make the biggest impact, and how small daily choices compound over years.

120. Jess Kane: Your Cells Are Leaking, Here's How to Fix Them Dec 11, 2025

Show notes

Have you ever wondered why you can be "doing everything right" with your health and still feel inflamed, foggy, or depleted? The more I study longevity, the more I am convinced this has less to do with the latest hack and more to do with something very basic that we almost never talk about: the integrity of the cell membrane. Every process in the human body begins at the level of the cell membrane, and in today's world, that membrane is under constant attack from toxins, infections, chemicals, and everyday stressors.

In this episode of Extend, I sit down with Jess Kane to explore why phosphatidylcholine (PC) may be the most critical nutrient we're not talking about, how modern exposures create "leaky cells," and why nearly all of us are now deficient in the lipids required to keep our DNA, mitochondria, and metabolic pathways safe. We break down the original PK Protocol, the role of PC in detoxification and brain health, and the steps anyone can take to rebuild membrane resilience and restore energy at the cellular level.

Jess Kane is the Chief Marketing Officer and third-generation co-owner of BodyBio, a family-led company pioneering science-backed solutions for cellular health, mitochondrial support, and anti-toxin resilience. She blends strategic insight with deep biochemical knowledge, helping BodyBio earn the trust of more than 35,000 healthcare practitioners worldwide. Jess is dedicated to educating the public on foundational lipids like phosphatidylcholine and the critical role they play in modern health.

What's Discussed:

(00:00) The "Bubble" Shield: How Your Cell Membrane Actually Works
(03:31) Leaky Cells: Toxins, Viruses, and the New Epidemic of Cellular Damage
(04:40) Fats That Build (or Break) Your Cell Membrane
(11:19) "Our Lipids Are Under Attack": Low-Fat Diets, Modern Toxins, and Metabolic Chaos
(15:42) Detox, Rebuild, Repeat: Using PC, TUDCA & Glutathione to Repair from the Inside Out
(27:49) Brain Fog, Acetylcholine, and Why PC Is a Hidden Brain Nutrient
(33:35) Skin, Aging, and What Healthy Cells Actually Look Like
(37:23) Seed Oils, Oxidized Fats, and How to Swap In the Right Lipids

119. Dr. Rocio Salas Whalen: How To Lose Weight On GLP-1s Without Losing Muscle Dec 09, 2025

Show notes

Most people still think GLP-1s are "weight loss shots," but what we are really doing is changing biology at the level of appetite and inflammation, with ripple effects across future generations. In this conversation, I sit down with endocrinologist and obesity specialist Dr. Rocio Salas Whalen to unpack what these medications do inside the body and how to use them responsibly as part of a long-term health strategy.

We get into why "eat less, exercise more" failed so many patients, how family history, hormones, and aging drive obesity, and why GLP-1s must be paired with protein and strength training. We also explore GLP-1's impact on visceral fat, diabetes, brain health, what healthy weight loss looks like on a body composition scan, and how to avoid sarcopenia and the so-called "Ozempic face."

Dr. Rocio Salas-Whalen is a board-certified endocrinologist and obesity-medicine specialist, author of Weightless, and an early adopter of GLP-1 therapies. Her so-called "GPS framework", GLP-1, protein, and strength training, reflects her approach to evidence-based obesity care.

What's Discussed:

(00:00) GLP-1s and Weight Loss

(12:45) The Impact of GLP-1 Hormone

(25:29) Muscle Mass and GLP-1 Importance

(31:46) Optimizing Protein Intake on GLP-1

(43:24) GLP-1 Dosing and Gut Health

(48:20) Mental Health Implications of Weight Loss

(57:16) Weightless Book Pre-Order Announcement
