Extend Podcast with Darshan Shah, MD

Chronic inflammation, environmental toxins, and metabolic dysfunction continue to accelerate aging and chronic disease across modern populations. Many of the biggest drivers of health decline remain invisible, quietly accumulating in the body for decades before symptoms appear.
In this episode of Extend, we sit down with Dr. Terry Grossman, physician, longevity expert, and co author of Transcend and Fantastic Voyage with futurist Ray Kurzweil, to unpack the science behind therapeutic plasma exchange and its emerging role in longevity medicine. We break down how environmental toxins, microplastics, heavy metals, and chronic inflammation influence aging biology, why traditional medical testing often misses these risks, and how therapies like plasma exchange may help remove harmful compounds while improving key biomarkers linked to healthspan.
We also explore how advanced diagnostics, hormone optimization, peptide therapies, and targeted longevity protocols may help individuals move beyond disease management toward true biological optimization.
Dr. Terry Grossman is a pioneer in anti aging and longevity medicine who operates longevity clinics in Colorado and co authored two best selling books with Ray Kurzweil. He is also the author of Plasma Reset, the first book focused on therapeutic plasma exchange as a strategy for detoxification, anti aging, and long term health optimization.

Chronic symptoms often get labeled, managed, and medicated, yet the root cause can remain hidden. Parasites, mold exposure, Lyme disease, and microbial imbalances may quietly disrupt energy, digestion, immunity, and cognitive clarity for years without being recognized.
In this episode of Extend, we sit down with Kim Rogers, founder of RogersHood Apothecary and creator of the ParaFy Kit, to unpack the hidden role parasites may play in chronic illness and why this topic remains largely absent from conventional medicine. We break down how parasite exposure can occur through water, food, pets, and environmental toxins, why standard testing frequently misses infections, and how symptoms like bloating, brain fog, fatigue, teeth grinding, and insomnia may point toward deeper biological disruption.
We also explore how a structured cleanse protocol using targeted herbs, binders, and supportive detox strategies may help the body remove parasites, heavy metals, and microbial overgrowth while restoring gut balance and energy.
Kim Rogers is a former Western healthcare educator and curriculum author who spent more than two decades working inside the medical system before her own health crisis led her to uncover parasites as a major driver of chronic illness, eventually building a global community and wellness company dedicated to helping people reclaim control of their health.
What We Discuss:
(01:31) Why parasites are a major blind spot in Western medicine

(02:32) Kim's health story and what led her to parasites

(04:14) The root cause stack: parasites, mold, and chronic Lyme, plus a hysterectomy at 29

(09:13) How exposure happens: water, raw fish, raw meat, produce, and pets

(10:31) Why symptoms can flare: biofilms, stress load, and immune strain

(12:38) Countries that normalize parasite prevention and access to antiparasitics

(13:50) Testing reality: LabCorp vs parasites.org and why false negatives happen

(18:02) Symptom patterns: bloat, IBS, teeth grinding, insomnia, cravings, brain fog, fatigue

(20:42) How she built the ParaFy Kit and why transparency and cost drove the business

(24:19) Protocol structure: 30 days, 3 to 4 times per year, dosing flexibility, kids 3 and up

(25:49) Binder rules: timing, what it does, and why it can interfere with meds

(29:31) Prescription options and the insurance cost gap versus Mexico pricing

(38:29) Why she wants better, affordable testing and medical reform

(41:45) Sushi, freezing myths, and why fish exposure is more common than people think

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.
What We Discuss:
(00:00) From surgery to longevity medicine and why sick care is broken
(06:30) A global health mission that changed Dr. Luu's view on prevention

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.
