EP 269. Your Gut Is Controlling More Than You Think: Health, Performance & Longevity with Dr. Zach Bush
What if optimizing your health isn't just about training, nutrition, supplements, and sleep—but about the trillions of microorganisms living within and around you? In this episode, Kris sits down with Dr. Zach Bush to explore the microbiome and its potential influence on everything from digestion and brain function to hormones, athletic performance, recovery, and longevity. Dr. Bush shares how his career evolved from conventional endocrinology into microbiome and environmental health research, and why he believes many of the health challenges we face today cannot be separated from the health of our soil, food systems, and environment. They discuss the impact of modern agriculture, antibiotics, glyphosate, declining nutrient density, and environmental exposures on the microbiome, along with practical ways to support greater microbial diversity and resilience. The conversation also explores the gut-brain axis, intermittent fasting, regenerative agriculture, and Dr. Bush's work developing Restore, including his theory that microbial communication may play a much larger role in human health and longevity than we currently understand. In This Episode: Why Dr. Zach Bush left conventional endocrinology to study the microbiome How soil health and modern agriculture may influence human health and nutrition What antibiotics, glyphosate, and environmental exposures can do to microbial diversity The gut-brain connection and its relationship with mood, cognition, hormones, and neurological health Why gut integrity and microbial diversity may matter for athletic performance and recovery How modern farming practices have changed the nutritional landscape of our food Intermittent fasting and the potential benefits of giving the gut time to repair Why different people can respond very differently to the same foods and diets The connection between our environment and microbiome resilience Regenerative agriculture and rebuilding healthier soil ecosystems The science and thinking behind Restore and microbial communication How supporting the microbiome could influence resilience, healthspan, and longevity Timestamps: 00:00 – Why microbiome health matters for fitness, health, and longevity 02:12 – Dr. Zach Bush's journey from endocrinology to microbiome research 05:12 – How chemicals, pollutants, and our environment may influence human health 06:57 – The gut-brain axis: microbiome, mental health, and neurochemistry 09:36 – Has modern agriculture changed the nutrient density of our food? 12:24 – Antibiotics, glyphosate, microbiome diversity, and gut integrity 15:41 – Inflammation, gut barrier function, and athletic performance 18:36 – What animal agriculture can teach us about the microbiome and performance 20:27 – Gut health, testosterone, growth hormone, and neurochemicals 22:33 – Organic food, dietary diversity, and finding what works for the individual 26:06 – Intermittent fasting, gut repair, and hormonal health 29:24 – Why there is no universal "perfect diet" for the microbiome 33:03 – How your environment shapes microbiome resilience 36:25 – Supporting microbial diversity through food, lifestyle, and environment 41:15 – Microbial communication and its potential role in chronic disease 45:50 – Soil health, regenerative agriculture, and the future of human health 50:29 – Restore: the formulation, research, and theory behind it 56:28 – Cellular repair, resilience, and longevity 1:03:25 – "Cellular Wi-Fi": understanding microbial communication 1:08:00 – Travel, environmental exposures, and supporting the microbiome 1:10:50 – The bigger picture: restoring the health of our soil, microbiome, and future generations Resources & Links: PLEASE NOTE: Restore is now Ion* Gut Support Glyphosate / Roundup Information Connect with Dr. Zach Bush: Website Instagram Thank you to our sponsors: Biostack Labs<

268. Biohacking's Blind Spot: What Bryan Johnson's Autoimmune Diagnosis Reveals
Bryan Johnson's recent autoimmune diagnosis has sparked an important conversation throughout the biohacking community. In this episode, Kris Gethin explores what this moment means—not as a criticism of Bryan's dedication, but as an opportunity to ask bigger questions about health, longevity, and the limits of optimization. Kris discusses the difference between collecting health data and creating true health, why modern lifestyles often disconnect us from our biological foundations, and how factors like sunlight, movement, grounding, nutrition, and resilience may matter more than endlessly stacking interventions. This episode is a reminder that while technology can be an incredible tool, it should support our biology—not replace it. Ultimately, longevity may depend less on eliminating every risk and more on working with the way humans were designed to live. In This Episode What Bryan Johnson's autoimmune diagnosis means for the future of biohacking Why more health data doesn't always translate to better health The difference between optimizing biomarkers and optimizing human biology How modern indoor living affects health, resilience, and longevity Why sunlight, movement, grounding, and nature remain foundational Animal-based nutrition vs. plant-based diets for performance and healthy aging The importance of preserving muscle as we age EMF exposure: what we know, what we don't, and practical ways to reduce it Why resilience—not eliminating every challenge—is essential for long-term health The role of humility, curiosity, and evolving with new scientific evidence Timestamps 00:00 – Bryan Johnson's autoimmune diagnosis and why it matters 00:23 – The dedication behind modern biohacking 00:50 – Are we pursuing optimization at the expense of biology? 01:17 – Did lifestyle cause the autoimmune condition? 01:46 – Respecting pioneers while continuing to ask questions 02:14 – The difference between tracking health and creating health 02:42 – When technology becomes overcomplication 03:12 – The environment humans were designed for 03:41 – Using technology to support biology—not replace it 04:10 – Why sunlight, movement, and circadian rhythms matter 04:36 – The health costs of modern indoor living 05:03 – Building resilience instead of avoiding every challenge 05:33 – Adaptation as a cornerstone of longevity 05:59 – Animal protein vs. plant-based nutrition 06:27 – Nutrient density and healthy aging 06:55 – Why muscle is

265. The Free Health Habits That Make Biohacking Work
Biohacking has become the new status symbol. Everyone wants the chamber, the wearable, the peptide, the IV, the stem cells, the red light, and the expensive recovery tool. But there is a problem most people do not want to admit: the body may not respond to the expensive stuff if the foundation underneath it is weak. In this episode, I'm talking about the part of biohacking that does not look impressive online but changes how well everything else works. The part people skip before they spend thousands trying to fix their energy, sleep, recovery, hormones, body composition, inflammation, focus, and health span. It is not that advanced tools have no place. It is that your body has to be in a position to use them. I also share where advanced biohacking tools fit into my own routine, and why I think the order matters. If you have been chasing the newest longevity tool, tracking every metric, or wondering why you still do not feel the way you want to feel, this episode will make you rethink what actually makes biohacking work. What's Discussed: Why the most expensive biohacks can still miss the real problem. What people are really trying to buy when they chase better energy, sleep, recovery, and health span. The lifestyle gaps no device, compound, clinic, or recovery tool can cover for you. The free layer of biohacking most people underestimate. Why the body needs the right foundation before advanced tools work well. The fat-loss and health-span mistake that can leave people lighter but weaker. How to use data, recovery tech, supplements, and advanced tools without turning them into expensive entertainment.

Can Tesamorelin Help You Burn Fat and Age Better?
Discover the science behind Tesamorelin, a research peptide targeting visceral fat and promoting health span. Kris Gethin breaks down its mechanisms, research findings, and implications for fat distribution and longevity. Tesamorelin is a synthetic analog of growth hormone release hormone (GHRH), stimulating the pituitary to release endogenous growth hormone rather than supplying synthetic GH. It primarily targets deep visceral fat, especially around organs, instead of just superficial subcutaneous fat. Visceral fat is linked to metabolic diseases, inflammation, insulin resistance, and overall aging; reducing it can extend health span. Research shows Tesamorelin reduces visceral fat by approximately 14-18% over 26 weeks without significant weight change. Unlike appetite suppressants like GLP-1 agents, Tesamorelin is considered weight-neutral, aiming for fat redistribution rather than broad weight loss. The effects on body composition include improved fat distribution, preservation of lean mass, and healthier metabolic markers. It can influence glucose tolerance and may cause fluid retention, joint pain, or injection site reactions, especially in older or metabolic-compromised individuals. Optimizing lifestyle factors such as sleep, nutrition, and stress management is crucial, as environment impacts visceral fat accumulation. Measuring waist circumference, visceral fat via imaging, blood markers, and metabolic health indicators are essential for tracking progress. Use of peptides like Tesamorelin should be under medical supervision within a broader health and lifestyle strategy.

262. The Food Label Lie: Why Your "Healthy" Food May Not Be What You Think with Will Harris
Most people think they know what they're eating because they read the label. Grass-fed. Organic. High protein. Product of the USA. Low calorie. Clean ingredients. But that label is the end of the story, not the beginning. The beginning is the soil. The animal. The feed. The farm. The chemicals. The confinement. The way the food was raised, processed, mixed, marketed, and sold before it ever reached your plate. And that's where a lot of people are getting fooled. In this episode of The Kris Gethin Podcast, I sit down with Will Harris, fourth-generation farmer and owner of White Oak Pastures, to break down what most people never see about the food system. We talk about why industrial food became built around cheapness, volume, and taste, why regenerative farming is the opposite of that model, and why knowing your farmer may tell you more than any label ever could. Will Harris is the fourth-generation owner of White Oak Pastures in Bluffton, Georgia. After decades in industrial cattle farming, he rebuilt the farm into a regenerative, multi-species operation focused on soil health, animal welfare, nutrient-dense food, and restoring local food systems. What's Discussed: How White Oak Pastures became a fourth-generation family farm. Why Will walked away from the industrial farming model he was trained in. How regenerative farming changed his soil organic matter from 0.5% to 5.5%. Why modern food became built around cheapness, volume, and taste. What "Product of the USA" labeling actually meant for years. What most people don't know about supermarket ground beef. Why real animal welfare includes instinctive behavior, not just food and water. Listen to this episode if you want to understand what's really behind your food, why the source matters, and why the farmer behind the product may be just as important as the label on the package.
