Extend Podcast with Darshan Shah, MD

A lot of us are doing everything we can to stay healthy, taking supplements, wearing trackers, getting our labs done, and still ending up sick. And if you are like most people, you probably thought that was on you, that you were not disciplined enough, not consistent enough, or simply not doing the right things, but that is not the case. The system we have been relying on was never designed to keep us well in the first place, and expecting the Western medical system to manage your long term health is like expecting a fire department to landscape your garden. 
We dive deeper into this in the Extend with Steve Martocci, Pranitha Patil, and John Sullivan. We also chat about why 30% of people have dangerously high blood pressure and have no idea, why four out of six top selling creatine products on Amazon contain zero creatine, and why doctors receive zero training on supplements in medical school yet are expected to advise patients on them every single day. 
Steve Martocci is the founder of SuppCo, a platform that has catalogued over 300,000 supplement products and built the industry's first independent trust scoring system. Pranitha Patil is the co-founder and Chief Business Officer of Function Health, which offers comprehensive lab testing across hundreds of biomarkers for $365 a year. John Sullivan is a senior leader at Whoop, the performance wearable that introduced medically cleared continuous health monitoring to everyday consumers. If there is any panel qualified to tell you the truth about what it actually takes to stay healthy in 2026, it is this one.
What's Discussed:
(13:12) The supplement industry's trust problem and why four out of six top selling creatine products on Amazon contain zero creatine.

(20:17) How to build your own N-of-1 health roadmap using lab work, wearables, and supplements working together.

(39:58) The single highest leverage investment you can make for your health right now that has nothing to do with money.

(43:26) Why 30% of people have dangerous blood pressure and have no idea.

(46:50) The FDA, the supplement industry, and where the line should actually be drawn between regulation and innovation.

(53:12) Why the Western medical system was never built to keep you healthy and what to do instead.

Listen to this episode of the Extend Podcast and finally understand why the system you have been trusting with your health was never designed to keep you well, and what it actually looks like to take that power back into your own hands.

Most high performing executives will spend thousands optimizing their glucose levels, their sleep, and their body composition without ever stopping to ask why none of it makes them feel any better. The answer almost never lives in their labs and it almost never lives in their training program. It lives in the identity they built their entire career on top of, and the silent narrative driving every decision they make, that tells them their worth is only as good as their last result.
In this episode of Extend, I sat down with Steve Chua to explore the real root cause of executive burnout and why fixing your physiology without addressing your identity is like putting the right fuel into the wrong engine. Walk away from this conversation with a completely different understanding of what is actually driving your performance, your exhaustion, and what it is going to take to finally lead from a place of genuine strength instead of fear.
Steve Chua is an executive life and leadership coach with over 30 years of experience working with international leaders and organizations, and the founder of Steve Chua International and InsightOut, a coaching and consulting firm that empowers leaders to grow from the inside out. He operates from the conviction that healthy leaders create healthy companies, and his unique ability to help individuals resolve past conflicts, gain clarity in the present, and align their purpose and vision for the future, has made him one of the most sought after leadership coaches in the world.

What's Discussed:
(3:24) Steve's personal story of comparing himself to his brothers, failing out of Oxford, and standing on the ledge of a building at his lowest point.

(5:57) The difference between living for value and living from value and why most executives are running on the wrong fuel.

(7:46) The three levels of identity work that create lasting change: self awareness, self management, and self leadership.

(11:34) Why picking up your phone first thing in the morning is the equivalent of eating a sugary breakfast for your brain.

(21:06) Why high achieving executives become the bottleneck of their own companies and what that reveals about their identity.

(37:49) The three things people lose when they burn out and why burnout is almost never just about working too hard.

(44:10) Why your 40s and 50s are not a midlife crisis but a shift from success to significance.

(51:30) The four life questions that when answered change everything about how you lead and how you live.

A lot of people are walking around exhausted, foggy, moody, and struggling with their cardiovascular health blaming stress, diet, age, and everything in between, never once considering that the real culprit might be happening in the eight hours they are not even awake for. And in children, what is being labeled as ADHD and treated with medication could in many cases simply be an undiagnosed sleep disorder that nobody thought to look for.
In this episode of Extend, I sit down with Dr. Meredith Broderick for a conversation that is going to completely reframe the way you think about sleep and what ignoring it is actually costing your health, your brain, and your children. Walk away finally understanding what is driving your symptoms, why the medications most people reach for are quietly making things worse, and what actually works to fix your sleep for good.
My guest today is Dr. Meredith Broderick, a triple board-certified sleep neurologist and one of only four practitioners in the world to hold certifications in neurology, sleep medicine, and behavioral sleep medicine. What makes her truly unique is how she brings together holistic, preventative, and behavioral approaches to sleep medicine in a way that almost no one else in this field can.There is truly nobody more equipped to have this conversation than someone who has spent her entire career at the exact intersection of the brain, the body, and the behavior of sleep.
 
WHAT'S DISCUSSED:
(7:29) Why children with sleep disorders are being misdiagnosed with ADHD and put on medication before anyone checks their sleep.
(8:45) The signs of a sleep breathing problem in children that most parents and pediatricians completely miss.
(13:48) Why sleep apnea is not just a snoring problem and how it silently drives cardiovascular disease, Alzheimer's, and even cancer.
(18:35) The surprising connection between mouth breathing, tongue position, and sleep apnea that nobody is talking about.
(36:34) What chronic insomnia actually is, why one in three people has it, and why most people are treating it completely wrong.
(40:19) What cognitive behavioral therapy for insomnia actually is and why it outperforms every sleeping pill on the market.
(55:01) Why Ambien may be blocking the brain's ability to clear the toxins linked to dementia while you sleep.
(1:11:03) The two or three sleep environment changes that make an immediate and measurable difference in sleep quality.
 
Listen to this episode of Extend and finally understand why your exhaustion, brain fog, and mood issues may have nothing to do with stress or age, what your sleep is actually doing to your long term health, and what it takes to fix it in a way that changes everything.

Fatigue, brain fog, weight gain, hair loss, low libido, high cholesterol, and a doctor who keeps telling you your labs look normal. For the millions of people walking around with an undetected or poorly managed thyroid condition, this is not just a frustrating experience but a dangerous one. Because what their doctor never told them is that the most important thyroid marker, the one that actually powers every cell in the body, is only being checked 4% of the time, which means the test they are relying on to rule out a thyroid problem is missing it almost every single time.
In this episode of Extend, I sat down with McCall McPherson for a conversation that is going to completely change the way you think about your thyroid, your labs, and why the treatment that 89% of thyroid patients are on may be the very reason they are still suffering. If you have ever been dismissed by your doctor despite feeling terrible, this episode is going to give you the language, the labs, and the clarity to finally get the answers you deserve.
McCall McPherson is a licensed Physician Associate, founder of Modern Thyroid Clinic, a practice with over 15,000 patients and hundreds of thousands of data points behind its approach, a TEDx speaker, and a 2024 Inc. 5000 honoree. She became one of the most sought after thyroid specialists in the country not just because of her clinical expertise but because she spent years as a thyroid patient herself, spending 16 hours a day in bed at 27 while being told her labs looked completely fine. There is nobody more qualified and nobody more personally invested in getting this right than she is.
WHAT'S DISCUSSED:
(2:12) The symptoms that signal a thyroid problem and why doctors keep dismissing them.

(4:38) Why every person with low testosterone needs to get their thyroid checked immediately.

(5:14) The three windows in a woman's life when thyroid disease risk spikes dramatically.

(6:12) What Hashimoto's actually is and why medicine is treating it completely backwards.

(11:46) Why TSH alone is missing the problem 96% of the time and what to ask for instead.

(16:38) What reverse T3 is and why elevated levels are silently blocking your thyroid hormone.

(35:15) Why subclinical hypothyroidism carries a 68% increased risk of heart attack and why medicine still is not treating it.

(38:53) McCall's personal story of spending 16 hours a day in bed at 27 while being told her labs looked completely normal.

Listen to this episode of Extend and finally understand why your labs have been coming back normal while your body has been telling you something is very wrong, what to ask your doctor to test, and what it actually takes to get your thyroid, your energy, and your life back.

Biological aging is no longer just a concept tied to time. It is something we can now measure, track, and influence through data, lifestyle, and targeted interventions that directly impact how our cells function and age.
In this episode of Extend, we sit down with Dr. Kara Fitzgerald, functional medicine leader, researcher, and author, to unpack how diet and lifestyle can directly influence epigenetics and biological age. We break down the difference between chronological and biological aging, how epigenetic clocks work across organs and systems, and why aging may be driven by both environmental exposures and deeper programmed mechanisms.
We also explore how polyphenols, nutrient-dense diets, and emerging interventions like Yamanaka mimetics may begin to shift the trajectory of aging at the cellular level and open new pathways for extending healthspan and peak performance.
Dr. Kara Fitzgerald is a functional medicine physician, researcher, and author of Younger You, known for her pioneering clinical studies demonstrating how targeted nutrition and lifestyle interventions can reverse biological age and reshape long-term health outcomes.
 
What We Discuss:
(01:36) Aging, performance, and menopause

(05:01) Healthspan vs peak span

(08:39) The dark matter of nutrition

(11:36) Polyphenols and urolithin A

(13:12) Biological age and epigenetics

(15:41) Epigenetic clocks and measurement

(21:02) Exposomic aging
