TBD Fit

On this episode, I sit down with Dr. Pat McShane, who spent about 40 years in reproductive medicine and fertility before turning her attention to women's healthspan. We talk about why so much of conventional care was built on male standards, and why so many women reach midlife feeling dismissed. Dr. McShane walks through what she learned across four decades, from the early days of IVF to the factors that shape fertility today, incl...

In this episode, I sit down with Ashok Gupta, who got into this work the hard way. He was an undergraduate at Cambridge in the mid-nineties, burning the candle at both ends, when a virus knocked him down and never fully let go. He could not read a page. He had no energy. His doctor told him there was no treatment and he might have it for life. His response was to go find the answer himself, which in the pre-internet era meant a boo...

We spend decades trying to kill our microbes, then wonder why we can't heal. In this episode of TBD Fit, I sit down with Dr. Dushyant Viswanathan (Dr. DV), a triple board-certified integrative internist, to rethink chronic disease from the gut up. We get into why so many of us are walking around with a "sterilized" microbiome, the difference between prebiotic and antibiotic forces acting on the body, and how the gut talks to the br...

A cancer diagnosis can feel like the ground disappearing. Dr. Michael Karlfeldt's message is that the ground you build long before then, and the team you build after, both matter.

On this episode of TBD Fit, I sit down with Dr. Michael Karlfeldt for a prevention-first, whole-person conversation about cancer risk. We talk about the lifestyle foundations he believes shape resilience, the labs he watches to catch problems early, and ho...

In this episode I sat down with John Nieters, and it is one of my favorite kinds of conversations, where an ancient tradition and modern science turn out to be describing the same things in different languages. John has spent a lifetime in Traditional Chinese Medicine, and he walks through how much a trained practitioner can read from the tongue and pulse, and how those observations line up with what we now understand about the bod...

Welcome to the TBD Fit podcast on DrTalks. In this one I sat down with Dr. Bobby Dubois, and it is the conversation I wish everyone would have before they buy the next longevity gadget or supplement. Bobby's whole message is about the difference between something sounding true and something being true. His filter is clean: a cool mechanism, a good anecdote, and a credentialed expert telling you to do it is not evidence, evidence co...

On this episode of TBD Fit, I sit down with Dr. Liz Bartman, the Chief Medical Officer at EndoAxis, for a conversation about the part of hormone health most people never see. Her north star is simple: test, don't guess. Before she recommends anything, she wants the data, not a snapshot, but the whole story of how your body is making and clearing its hormones.

We break down the three ways to test, blood, saliva, and urine, and why ea...

We spend a lot of time on this show talking about the body, so I loved turning toward the mind for a while. Phil Sarpong brings a clinical psychologist’s view of how deeply the two are linked, starting with trauma. His smoke-detector picture stuck with me: the same alarm that keeps us safe can get oversensitive and start firing when there’s no real danger, which helps explain why two people can live through the same eve...

This is one of those conversations that reminds you how much of health is detective work. Valerie Orsoni has spent more than two decades treating her own body like a lab, tracking her numbers, changing one thing at a time, and paying close attention to what the data actually says. We get into how she measures inflammation and pace-of-aging at home, and how following the trail eventually led her to mold-related toxins and gut imbala...

When a patient tells me a peptide "didn't work," my first question is never about the peptide. It's about everything around it. In this episode of TBD Fit, I sat down with Dr. Gordon Crozier, DO, one of the most detailed clinicians I know, to talk through why cellular repair succeeds or fails long before the injection ever happens.

We get into his own recovery from mold, Lyme, and Crohn's, why he is so particular about where his glu...

In this episode, I sit down with Dr. Joe Sherman, a pediatrician whose career has taken him from academic health centers in the US to clinics in Uganda and Bolivia, and who now spends his time helping other clinicians stay whole. We start where a lot of parents live right now: one in two kids carrying a chronic health condition, a chemical soup most of us were born into, and screens that reshape how young brains work. Joe's take is...

In this episode, I sat down with Dr. Haroldo Magarinos to make sense of something that touches every patient I see: the sheer chemical load of modern life and what it does to the gut. We start with the big picture, how the rise in chemical production tracks alongside the rise in chronic illness, and then get specific about the mechanisms. Heavy metals that hide in fatty tissue, glyphosate that crowds out the building blocks your bo...

In this episode, I made the trip to Holland, Michigan to see Dr. Ryan Bentley's work up close, because I wanted to understand therapeutic plasma exchange from the inside, not just read about it. We start with the problem: we are all carrying a toxic load our great-grandparents never faced, from forever chemicals and microplastics to mold and heavy metals, and most of it never shows up on a standard panel. Dr. Bentley walks me throu...

In this episode, I visit Blake Miller at his lab to talk about something most health conversations skip past: oxygen. Blake has worked with ozone therapy since the late 1990s, and he walks me through what ozone actually is, an oxygen molecule that picks up a third atom when it meets an electrical charge, and why he organizes his whole approach around hydration, mineralization, and oxygenation.

We get into how he thinks about toxic b...

Success looks different when it is built with intention, trust, and health at the center. In this episode of The TBD Fit Podcast, Ashton and Angela Wilson join Dr. Daniel Chille in Las Vegas to share how their paths moved from healthcare, fitness, nursing school, and hospital work into sales, business ownership, software, and Active Solutions.

The conversation explores the skill sets that changed their lives, including personal deve...

Lyme disease isn't just about the infection—it's about the environment inside your body that allows it to persist. In this episode of The TBD Fit Podcast, Dr. Darin Ingels shares how his own experience with Lyme reshaped his entire approach to healing. After cycling through antibiotics without results, he discovered that recovery required more than targeting the bacteria—it required rebuilding the body itself.

The conver...

This generation of teens isn't just struggling—they're being shaped by a system that disconnects them from how the body is meant to function.

In this episode of The TBD Fit Podcast, Abdullah and Zain Ansari share their journey from chronic symptoms like eczema, dizziness, and poor nutrition to becoming advocates for real food, mindfulness, and intentional living. What started as personal healing turned into a mission to educat...

Sometimes the life you lose becomes the voice you were meant to use. In this episode of The TBD Fit Podcast, Darryll Stinson shares his journey from insecurity, bullying, and high-performance athletics to injury, identity loss, and the painful season that forced him to rebuild from the inside out.

The conversation explores how Darryll uncovered purpose, developed his communication framework, and learned to turn pain into service. He...

Most people think oral health is about teeth, but the mouth is actually one of the most powerful drivers of inflammation in the entire body. When the oral microbiome becomes imbalanced, bacteria, toxins, and immune signals spread far beyond the gums, influencing digestion, hormone balance, cardiovascular risk, brain health, and chronic inflammation.

In this episode of The TBD Fit Podcast, we explore how biological dentistry reframes...
