Extend Podcast with Darshan Shah, MD

Strength is the foundation of longevity. When muscle, cardiovascular fitness, mobility, balance, sleep, and nutrition align, performance improves, metabolism sharpens, and aging becomes something you influence rather than fear.
In this episode of Extend, we sit down with Fitz Koehler, founder of Fitzness.com, keynote speaker, race announcer, and five time author, to unpack her Four Pillars of Fitness and the exact formula for sustainable weight loss and long term vitality. We break down the difference between activity and deliberate exercise, why toning is a myth, how the grunt, huff, wince, and wobble signal true adaptation, and how a simple calorie budget paired with high quality nutrition preserves muscle while reducing fat.
We also explore how discipline outperforms motivation, why sleep and strategic naps accelerate recovery, how strength training protects bone and balance during menopause and aging, and how tracking weight, reps, and daily habits creates measurable progress over time.
Fitz Koehler is one of America's most electrifying keynote speakers, a premier race announcer, fitness innovator, host of The Fitzness Show podcast, and five time author whose latest book You Supercharged! The Exact Formula for Fitness, Weight Loss, and Longevity is helping people worldwide build strength, resilience, and lasting health.

Most people think medicine is about treating disease. What if the real future of healthcare is preventing illness and optimizing human potential long before symptoms appear.
In this episode of Extend, we sit down with Dr. David Luu, physician, former pediatric cardiac surgeon, and founder of the Longevity Docs movement. Dr. Luu shares his journey from high intensity surgery to longevity medicine, shaped by firsthand exposure to preventable disease, global health missions, and the realization that the current medical system is built for sick care, not health.
We explore where longevity medicine is today, where it is heading, and why AI, wearables, and data access are transforming how people manage their health. Dr. Luu breaks down the shift from biohacking to bioliteracy, the need to train doctors as educators, and his Longevity Canvas framework for building a life that prioritizes both time and vitality.

Raising healthy children today requires more discernment than ever. Between conflicting vaccine guidance, ultra processed food marketing, and the explosion of screen exposure, modern parents are navigating a landscape filled with noise and strong opinions.
In this episode of Extend, we sit down with Dr. Joel Warsh, board certified pediatrician and founder of Integrative Pediatrics, to unpack how parents can think critically about vaccine schedules, evaluate medical credentials online, and make informed decisions rooted in both data and context. We break down the evolving CDC recommendations, shared clinical decision making, the food pyramid reset, ultra processed food exposure, sugar overload, seed oil debates, dairy questions, allergy desensitization, screen time guardrails, and the real risks of repetitive head injuries in youth sports.
We also explore how practical changes at home such as reducing added sugar, setting clear screen boundaries, prioritizing real food, and fostering open medical conversations can meaningfully shape a child's long term metabolic and neurological health.
Dr. Joel Warsh, also known as DrJoelGator, is a board certified pediatrician based in Los Angeles specializing in parenting, wellness, and integrative medicine. He holds a Master's degree in Epidemiology, trained at Children's Hospital of Los Angeles, and is the author of Between a Shot and a Hard Place, where he tackles complex vaccine questions with balance, data, and clarity.

Chronic stress is quietly reshaping how we think, perform, sleep, and recover. In a world optimized for productivity, we rarely prioritize the one variable that determines long term resilience: recovery.
In this episode of Extend, we sit down with Dr. Dave Rabin, neuroscientist, psychiatrist, and co founder of Apollo Neuro, to unpack the science of vagal tone, heart rate variability, and how safety signals in the body drive peak performance and mental health. We break down the difference between eustress and distress, how unresolved trauma suppresses recovery, why HRV may be the most powerful biomarker of resilience, and how tools like breath, environment design, and wearable neurotechnology can retrain the nervous system in real time.
We also explore how psychedelic assisted therapies such as ketamine and MDMA are reshaping psychiatry, why safety is the foundation of trauma healing, and how small daily practices can restore autonomic balance and unlock human potential.
Dr. Dave Rabin, MD, PhD, is Executive Director of The Board of Medicine and a psychiatrist and neuroscientist specializing in chronic stress and treatment resistant illness. He has spent 15 years researching non invasive therapies including MDMA assisted treatment for severe PTSD, and is the author of the upcoming book A Simple Guide to Being Alive, a science backed framework for navigating burnout and reclaiming mental clarity in the modern world.

Fertility is declining while menopausal symptoms are appearing earlier. Metabolic dysfunction, chronic stress, and environmental exposures are reshaping reproductive health for both women and men.
In this episode of Extend, we sit down with Dr. Mao Shing Ni, co founder of Tao of Wellness and Yo San University of Traditional Chinese Medicine, to unpack how Eastern medicine and modern science can work together to optimize fertility, support egg freezing outcomes, and reframe menopause as a powerful Second Spring. We break down sympathetic versus parasympathetic signaling, how stress suppresses ovulation, why metabolic health drives PCOS and sperm quality, and how acupuncture, targeted herbs, infrared therapy, and nutrition strategies can increase live birth rates and extend hormonal vitality.
We also explore how tools like continuous glucose monitoring, berberine, GLP 1 support, Tai Chi, sleep optimization, and strategic hormone therapy can shift reproductive biology at any stage, from preconception to menopausal transition.
Dr. Mao Shing Ni, DOM, PhD, LAc, is a 38th generation doctor of Traditional Chinese Medicine with over 40 years of clinical experience in integrative longevity, reproductive, and anti aging medicine. He is the bestselling author of more than 20 books, including Secrets of Longevity, co founder of Tao of Wellness and Yo San University, and an internationally recognized speaker in reproductive, hormonal, and longevity medicine.
