Most people hear "saturated fat" and think of something harmful, yet emerging research reveals that one specific fatty acid supports stronger cell membranes, healthier metabolic function, and better long-term resilience. C15 plays a unique role in the biology of aging and may help explain why certain populations experience longer, healthier lives.

In this episode of Extend, we sit down with Dr. Stephanie Venn-Watson, veterinary epidemiologist and co-founder of Fatty15, to uncover how Navy dolphin research led to the discovery of C15 as the first essential fatty acid identified in nearly a century. We unpack why odd chain fats behave differently than traditional dietary fats, how C15 stabilizes cellular aging pathways, and why declining levels in the modern diet may be contributing to metabolic and cognitive decline.

We also explore how C15's effects on ferroptosis, inflammation, liver markers, and mitochondrial efficiency offer a new way to support healthspan at the cellular level.

Dr. Stephanie Venn-Watson is a leading veterinary epidemiologist whose groundbreaking research on marine mammals revealed the essential role of C15 in aging, metabolism, and cellular integrity, ultimately leading to the development of the concentrated and clinically studied Fatty15 formulation.

What if the future of medicine isn't about diagnosing disease, but preventing it entirely? For decades, our healthcare system has only reacted once things go wrong. We measure when there are symptoms. We intervene when there is a crisis. But what if we could see the shift before it becomes an illness?

In this episode of EXTEND, I'm joined by Josh Clemente, founder of Levels and former SpaceX engineer, to explore how continuous health monitoring is about to change human health at scale. Josh shares how engineering principles—not traditional medicine—first revealed the hidden metabolic patterns that were draining his energy, affecting his cognition, and pushing him toward disease long before any lab test reflected it.

We discuss why continuous glucose monitoring is only the first step in this revolution, how data empowers individuals instead of the healthcare system, and why the next era of health will be defined by observability—real-time insight that lets you adjust, course-correct, and optimize your biology every single day.

Josh Clemente is the co-founder of Levels, a metabolic health platform bringing continuous glucose monitoring and real-time lifestyle coaching to the mainstream. Previously, he led life support systems engineering at SpaceX, where he developed safety technology for astronauts aboard the Crew Dragon spacecraft.

What if the key to living longer and feeling younger has been hidden in ancient medicine all along? Long before supplements, peptides, or wearables, healing was about restoring balance through food, movement, belief, and nature. Today, those same principles are being shown by modern science to protect your cells, extend your healthspan, and reverse root causes of disease.

In this episode of EXTEND, I'm joined by Dr. Josh Axe and we explore how ancient healing systems like Ayurveda and Traditional Chinese Medicine intersect with today's most advanced longevity research. We dive into the biology of faith and mindset, how chronic stress and emotion impact gene expression, and the connection between gut health, inflammation, and aging.

We also discuss how to bridge natural and modern medicine, the surprising role of peptides and stem cells in regeneration, and why true longevity begins with the everyday habits you practice, not just the protocols you chase.

Dr. Josh Axe, DC, DNM, CNS, is a doctor of chiropractic and natural medicine, a clinical nutritionist, and the co-founder of Ancient Nutrition. He is also the host of the podcast The Dr. Josh Axe Show and the bestselling author of Ancient Remedies and The Biblical Diet.

We Also Discuss: (00:04) Traditional vs. Western medicine and where real healing happens (08:51) Ancient nutrition and the science of longevity (14:31) The emotional biology of healing in Eastern medicine (25:55) Biblical health codes and the roots of longevity (38:06) Mold toxicity, early signs, triggers, and recovery (52:26) Illness, purpose, and the path to healing (01:12:38) Regenerative therapies using peptides and stem cells (01:27:59) The future of wellness through ancient wisdom and modern science

What if the real secret to longevity isn't found in science alone, but in how we choose to live, love, and connect every day?

In this special posthumous episode of EXTEND, I revisit one of the most meaningful conversations I've ever had — with Dr. Gladys McGarey, the 103-year-old physician known as the Mother of Holistic Medicine and author of The Well-Lived Life. Before her passing, Dr. McGarey shared a century's worth of wisdom on what truly heals us, from the inside out.

We talk about how she helped create the holistic medicine movement, the deeper meaning behind her "Five L's" — love, life, laughter, labor, and listening — and how energy, purpose, and community shape both health and happiness. She also shares powerful stories from her early life in India, her encounter with Gandhi, and how compassion became the foundation of her medical practice.

Dr. Gladys McGarey reminds us that medicine isn't just about curing disease — it's about nurturing the human spirit, and remembering that love itself is one of the most powerful healing forces we have.

We Also Discuss:

(00:00) A Century of Healing: The Life and Legacy of Dr. Gladys McGarey

What if the real turning point for women's health isn't menopause itself, but the decade before it? Long before the symptoms hit, your brain, bones, and heart are already changing, silently. You can train hard, eat clean, and still lose strength, bone density, and cognitive sharpness if you're not addressing the biology underneath it all.

In this episode of EXTEND, I'm joined by Dr. Vonda Wright, orthopedic surgeon, researcher, and author of Unbreakable, to talk about how women can take control of midlife long before the "change." We get into what actually happens when estradiol starts to fall, why bone is an active endocrine organ (not just structure), and how to measure what really predicts longevity: VO₂ max, grip strength, sit-to-stand, and bone quality.

We also discuss her FACE framework, flexibility, aerobic base, carrying load, and equilibrium, a smarter way to train for longevity that protects your brain, bones, and hormones.

Dr. Vonda Wright is a double board-certified orthopedic surgeon, researcher, and author of Unbreakable. She's a leading expert in active aging and musculoskeletal longevity, known for helping midlife women build strength, preserve bone health, and optimize performance through data-driven prevention.

You can eat clean, track your labs, take supplements, and still feel anxious, inflamed, tired, or flat. Why? Because the gut, brain, immune system, and hormones are in constant conversation, and most of us are only treating one side of that story.

In this episode of Extend, I sit down with Dr. Will Cole to uncover the science behind the gut-brain axis, and why nervous system dysregulation might be the reason your biomarkers won't budge. We unpack how microbiome imbalances, silent inflammation, low vagal tone, and stored trauma show up as anxiety, constipation, brain fog, and burnout… even when you're "doing everything right."

We also get practical: testing beyond standard blood work, HRV as a window into resilience, breathwork vs. meditation, EMDR, "ugly journaling," and when devices like Apollo Neuro and Sensate actually help.

Dr. Will Cole is a leading functional medicine expert, a pioneer in gut-brain health, neuroimmune disorders, and autoimmune healing. He is also the host of the top-ranked podcast The Art of Being Well and the New York Times bestselling author of books including Gut Feelings, The Inflammation Spectrum, and Ketotarian.
