In this episode of the Flex Diet Podcast, I’m joined by my good friend Dr. Eric Trexler, exercise scientist, educator, and Director of Education at Stronger by Science, for a wide-ranging, no-BS conversation on what physiology actually looks like in the real world.We dig into beetroot juice, nitric oxide, and “pump” supplements, why the blood-flow story is usually oversold, and why neuromuscular function and calcium handling may matter far more than chasing a swollen muscle. We also talk about why most supplement mechanisms sound great on paper… and quietly fall apart once you look at healthy humans who already function pretty well.From there, the conversation expands into human variability, elite athletic outliers, and why normal distributions actually guarantee that “freaks” exist — whether people are comfortable admitting it or not. We also unpack NEAT, energy expenditure, and why exercise doesn’t scale linearly for fat loss, including how the body aggressively manages its energy budget when stress or activity gets too high.If you care about performance, body composition, or just understanding how the human system really works, this episode will recalibrate a lot of assumptions.Sponsors:LMNT: http://drinklmnt.com/mikenelson (automatically applied at checkout)Fitness Insider Newsletter: https://miketnelson.com/Shiftwave: https://shiftwave.co/drmiketnelsonEpisode Chapters:05:01 Diving into Beet Root and Nitrate Research05:58 Mechanisms and Effects of Nitrate Supplements10:14 Challenges and Insights in Supplement Research34:19 Elite Athletes and Physiological Variability43:16 Debating the Value of Outliers in Research44:38 The Importance of Studying Rare Genetic Conditions45:46 Challenges in Grant Writing for Rare Conditions47:39 Blood Flow and Muscle Performance49:14 The Science Behind Muscle Pumps and Hypertrophy56:09 Energy Expenditure and Physical Activity58:02 The Non-Linear Relationship Between Activity and Energy Intake01:01:28 Exercise, Appetite, and Weight Management01:14:19 Balancing Cardio and Strength Training for Optimal Health01:21:14 Closing Remarks and Resources Episodes You Might Enjoy:Episode 352: Dr. Dan Pardi on Stem Cells, Supplements, and the Future of Health with QualiaYouTube: https://youtu.be/8EZcHy_7wK8?si=aNGzT-abP9xbc6yUEpisode 343: Fueling the Corporate Athlete: Stress, Supplements & Performance with Dan HunterYouTube: https://youtu.be/0ek4XSs62RQ?si=czR_7q96jJDqXzcFConnect with Eric:Instagram: https://www.instagram.com/trexlerfitnessGet In Touch with Dr Mike:Instagram: https://www.instagram.com/drmiketnelson/YouTube: https://www.youtube.com/channel/UCn1aTbQqHglfNrENPm0GTpgEmail: https://miketnelson.com/contact-us/

In this episode of the Flex Diet Podcast, I sit down with Dr. Jeremy Bettle, a performance director and applied sports scientist, to dig into what actually moves the needle for performance, recovery, and long-term resilience.We cover everything from high ankle sprains and injury prevention to smarter load management, and why understanding stress, recovery, and tissue capacity matters far more than chasing random training trends.Dr. Bettle shares insights from years of work across the NHL, NBA, and international sport, along with how elite performance systems can — and should — be translated to non-elite humans who want to train hard, recover better, and keep doing this for decades.Sponsors:Rogue: https://miket.me/rogueBeyond Power Voltra 1: https://www.beyond-power.com/michael13Fitness Insider Newsletter: https://miketnelson.com/Episode Chapters:05:26 Discussion Kickoff: Injury Prevention and Load Management06:10 High Ankle Sprains in Professional Sports15:07 Load Management Strategies and Challenges38:11 Eccentric Training and Injury Prevention46:23 Muscular vs. Soft Tissue Injuries in Athletes47:49 Importance of Plyometric Work in Injury Prevention51:43 Isometric Exercises and Their Benefits58:12 Recovery Strategies and Their Effectiveness01:08:02 The Role of Communication in Team Sports01:15:55 Systematizing Athlete Routines for Optimal Performance01:22:52 Conclusion and Final Thoughts Episodes You Might Enjoy:Episode 314: Unlocking Performance & Recovery: IV Therapies & Hyperbaric Oxygen Therapy with Jordyn PayneYouTube: https://youtu.be/qnJHcepDx1c?si=aTlDcFS6D77jq49DEpisode 325: The Uncommon Science of Cold: Brown Fat, Resilience & Recovery with Dr. Thomas SeagerYouTube: https://youtu.be/5ycoVRnLTuY?si=m-pgtYkkMcQhPUXJConnect with Jeremy:Vitality Collective: https://vitality-collective.com/Instagram: https://www.instagram.com/VitalityCollectivePerformanceGet In Touch with Dr Mike:Instagram: https://www.instagram.com/drmiketnelson/YouTube: https://www.youtube.com/channel/UCn1aTbQqHglfNrENPm0GTpgEmail: https://miketnelson.com/contact-us/

We also talk about her new book, The Concussion Breakthrough, and how it’s helping patients who’ve been struggling with long-term symptoms finally find a path forward.If you want a deeper understanding of how the brain heals — and how functional neurology can help you or someone you know recover faster and more completely — you’ll get a ton out of this conversation.Sponsors:Beyond Power Voltra 1: https://www.beyond-power.com/michael13Tecton Ketone Esters: https://tectonketones.comAvailable now:Grab a copy of the Triphasic Training II book I co-wrote with Cal Deitz here.Episode Chapters:00:46 Exploring Functional Neurology01:23 Concussions and Eye Movements02:09 Dr. Wolf’s Book and Newsletter02:42 Starting the Conversation02:49 Dr. Wolf’s Lecture at Northwestern03:40 Better PowerPoint Presentation Tips04:29 Challenges of Creating New Talks05:57 AI in Research and Presentation07:22 Cadaver Lab Experience in Toronto09:07 Acupuncture and Anatomical Research09:54 History and Acceptance of Chinese Medicine11:47 Skepticism and Evidence in Acupuncture13:41 Research Design Challenges17:18 Innovative Acupuncture Studies21:34 Psychedelics and Research23:15 Dr. Wolf’s Journey into Acupuncture27:08 Favorite Herbs and Their Benefits29:16 Introduction to Functional Neurology33:18 Case Studies and Clinical Insights35:59 Sensory Tricks for Migraines38:13 Mechanisms Behind Sensory Tricks39:32 Light Sensitivity and the Midbrain40:45 Personal Experience with a Health App41:31 Understanding Light Sensitivity42:59 Case Study: Pupil Response and Eye Pain44:09 Eye Movements & Concussion Diagnosis47:06 Gaze Stability and Neurological Insights52:19 The Concussion Breakthrough Book55:45 Complex Cases in Functional Neurology01:04:27 Visual + Vestibular Integration01:14:55 Final Thoughts and Resources Flex Diet Podcasts You May Enjoy: Episode 132: The Effects of Creatine Supplements on Brain Function, Concussion, and Sports Performance with Dr Eric RawsonYouTube: https://youtu.be/g7f8yHNlawU Episode 311: Maximizing Athletic Performance with Neurology: Insights from Dr. Dylan SeeleyYouTube: https://www.youtube.com/watch?v=bnuYQ-GJ6toConnect with Dr Wolf:The Concussion Breakthrough: https://www.amazon.com/Concussion-Breakthrough-Discover-Missing-Recovery/dp/B0FDBLVDVHWebsite: https://www.acupunctureneurology.com/Instagram: https://www.instagram.com/ayla_wolf354Get In Touch with Dr Mike:Instagram: DrmiketnelsonYouTube: @flexdietcertEmail: Miketnelson.com/contact-us

In this episode of the Flex Diet Podcast, I’m joined by Erin Silver Lee, the CEO of Flow Neuroscience. We dig into some seriously cool stuff — including Flow’s recent acquisition of the Halo device, which uses non-invasive brain stimulation (TDCS) to boost both athletic and mental performance.Erin and I talk about how this tech works, what the current research says, and how it’s being applied to improve focus, sleep, neuroplasticity, and overall brain health. We also get into the real-world side of things — from navigating FDA regulations to running clinical trials and shaping the future of personalized brain optimization.If you’re curious about where neuroscience meets performance — and how safe, evidence-based brain stimulation might fit into the next generation of recovery and training tools — you’ll want to check this one out.Sponsors:Beyond Power Voltra 1: https://www.beyond-power.com/michael13Tecton Ketone Esters: https://tectonketones.comAvailable now:Grab a copy of the Triphasic Training II book I co-wrote with Cal Deitz here.Episode Chapters:00:38 Background on Halo Device and Flow Neuroscience01:50 Acquisition and Technology Insights02:09 FDA Regulation and Consumer Approval06:02 New Device Focus and User Benefits07:29 Device Design and Usage08:45 Impact on Sleep and Mental Performance16:17 Personalization and Future Developments26:06 Focus and Concentration Benefits29:33 Navigating FDA Regulations30:35 Depression Treatment Success in Europe30:51 Challenges with Regulatory Approval31:50 Real-World Success and Halo Product Launch33:23 Navigating FDA Approval and Bias42:45 Clinical Trials and Expanding Indications51:25 Brain Health and Personal Practices55:33 Podcast Conclusion and Listener Information Flex Diet Podcasts You May Enjoy: Episode 346: From Navy SEAL to Neuroscience: Dr. Blaine Lints on Ibogaine and PerformanceYouTube: https://youtu.be/8UNGgyqBWm0 Episode 241: A New Perspective on Brain Health with Dr. Shaun KornfeldYouTube: https://youtu.be/1HcgPp6Wz7QConnect with Flow Neuroscience:Website: https://www.haloneuroscience.com/Facebook: https://www.facebook.com/halo.neuroscienceYouTube: https://www.youtube.com/@HaloNeuroscienceLinkedIn: https://www.linkedin.com/company/halo-neuroscience/Instagram: https://www.instagram.com/halo.neuro/Get In Touch with Dr Mike:Instagram: DrmiketnelsonYouTube: @flexdietcertEmail: Miketnelson.com/contact-us

In this episode of the Flex Diet Podcast, I dive into practical ways to boost muscle growth, enhance performance, and improve body composition — all within a flexible, health-focused framework.I also talk about my Physiologic Flexibility Certification, which is closing for enrollment soon, and unpack key concepts like Human Dynamic Range (HDR) and cross-adaptation. HDR is all about building a wider physiological range — the ability to handle more stress and recover faster — while cross-adaptation looks at how training one system (like heat or hypoxia) can improve others.Plus, I dig into new research and share actionable strategies you can use right now to strengthen your cardiovascular and respiratory systems.Sponsors:Physiologic Flexibility Certification Course open Monday, Oct. 13 to Monday, Oct. 20: https://miketnelsons.samcart.com/products/physflex/Instagram: https://www.instagram.com/drmiketnelson/Triphasic 2 book now available!Go to https://triphasic2.com/Episode Chapters:00:20 Important Announcement: Physiologic Flexibility Certification01:57 Key Concepts in Physiologic Flexibility02:14 Human Dynamic Range Explained06:01 Cross Adaptation: Heat and Hypoxia08:24 Research Studies and Findings20:33 Practical Applications and Protocols24:32 Conclusion and Certification Details28:21 Disclaimer and Final NotesGet In Touch with Dr Mike:Instagram: https://www.instagram.com/drmiketnelson/YouTube: https://www.youtube.com/channel/UCn1aTbQqHglfNrENPm0GTpgEmail: https://miketnelson.com/contact-us/

In this episode of the Flex Diet Podcast, I’m diving headfirst into the science of sleep with two heavy hitters—Dr. J Wiles and Dr. Jeff Dermer from Absolute Rest.We cover it all: why sleep is such a big deal from an evolutionary standpoint, how your modern lifestyle is probably trashing it, and what you can actually do to fix it. We dig into behavioral changes, the role of wearables versus legit lab sleep studies, and practical, no-BS strategies to get better shut-eye.Jay Wiles and Jeremy Durmer break down Absolute Rest’s comprehensive approach, examining the psychological, physiological, and environmental factors that influence sleep. Translation: it’s not just “buy a new pillow and call it good.”We also get into the fun stuff like caffeine, nicotine, and alcohol—how they mess with your recovery and performance—and why making small behavioral shifts and value-based choices can keep your sleep dialed in for the long haul.If you’ve ever wondered how to stop treating sleep like an optional side quest and instead make it one of your biggest performance enhancers, this one’s for you.Sponsors:LMNT electrolyte drink mix: https://drinklmnt.com/Get my free magnesium guide: https://miket.me/magAvailable now:Grab a copy of the Triphasic Training II book I co-wrote with Cal Deitz here.Episode Chapters:06:13 The Importance of Sleep: Evolutionary and Scientific Perspectives11:40 Sleep Deprivation Studies and Their Implications16:54 Unihemispheric Sleep: Can Humans Do It?25:00 Personalized Sleep Needs and Efficiency36:44 Personalized Sleep Assessment37:28 Subjective Experience in Sleep Quality38:20 Comprehensive Sleep Testing38:58 Autonomic Sleep Testing Explained39:32 Behavioral and Psychological Factors41:29 Polysomnography and Its Evolution47:23 Home Sleep Testing Innovations48:14 Cardiopulmonary Coupling and Sleep Quality56:35 Heart Rate Variability and Sleep01:06:44 Behavior Change and Value Systems01:13:50 Struggles with Sleep and Coaching Solutions01:14:27 Blocking Data to Improve Sleep Coaching01:14:58 Empowering Clients to Interpret Sleep Data01:15:41 The Importance of Sleep Regularity01:17:24 Caffeine and Nicotine's Impact on Sleep01:19:07 Genetics and Supplements in Sleep Health01:21:39 Behavioral Changes for Better Sleep01:27:35 Comprehensive Sleep Program Overview01:41:02 Addressing Sleep Issues in Children01:45:00 Podcast Conclusion and Resources Flex Diet Podcasts You May Enjoy: Episode 310: Unpacking the Science of Sleep with Dr. Allison Brager: https://miketnelson.com/episode-310-unpacking-the-science-of-sleep-with-dr-allison-brager/YouTube: https://www.youtube.com/watch?v=fhS0qsF1OHs Episode 283: Unlocking Better Sleep and Stress Reduction with Dr. Dan Cohen of Soltec Health: https://miketnelson.com/episode-283-unlocking-better-sleep-and-stress-reduction-with-dr-dan-cohen-of-soltec-health/YouTube: https://youtu.be/VInoz9ItGfwConnect with Jay and Jeremy:Absolute Rest: https://www.absoluterest.com/Get In Touch with Dr Mike:Instagram: DrmiketnelsonYouTube: @flexdietcertEmail: Miketnelson.com/contact-us
