Flex Diet Podcast

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

On this episode of the Flex Diet Podcast, I’m joined once again by Dr. Phil Batterson to nerd out on one of my favorite topics: anaerobic metabolism. We dig into what’s really happening during high-intensity training, the role of lactate, and why much of the “anaerobic vs. aerobic” discussion you hear is oversimplified (or just plain wrong).We also get into the nuts and bolts of how your bioenergetic systems adapt, why cardio equipment can actually be a powerful training tool, and where metabolic carts fit into the picture. Along the way, Phil drops practical examples you can use to better understand your own performance. If you want a clear, science-backed breakdown of anaerobic training without the fluff, this episode is for you.Sponsors:LMNT electrolyte drink mix: https://drinklmnt.com/Get your rower and assault bike at Rouge https://miket.me/rogueAvailable now:Grab a copy of the Triphasic Training II book I co-wrote with Cal Deitz here.Episode Chapters:04:58 Personal Updates and Business Insights12:37 Anaerobic vs. Aerobic Metabolism Discussion15:00 Training Techniques and Adaptations21:07 Challenges in Hybrid Training24:43 Exploring the ATP-PC System33:59 Introduction to Bioenergetic Systems34:05 Understanding Energy Systems in Exercise34:35 The Role of ATP and Phosphocreatine35:08 Intensity and Energy System Utilization35:46 Fatigue and Muscle Contraction36:38 Misconceptions in Exercise Physiology37:42 Lactate and Its Role in Exercise40:18 High-Intensity Training Adaptations41:46 VO2 Max and Training Protocols42:40 Balancing Aerobic and Anaerobic Training43:58 Effective Training Strategies55:00 Heart Rate and Performance Metrics01:00:07 Lactate: Myths and Realities01:09:30 Buffering Capacity and Adaptations01:16:03 BFR Bands and Intense Workouts01:16:38 The Importance of Cardiovascular Training for Lifters01:17:21 Debunking Myths About Cardiac Development01:18:04 Anaerobic and Aerobic Training Insights01:18:47 Effective Aerobic Training Strategies01:19:42 Maintaining VO2 Max with Minimal Effort01:20:12 Mitochondrial Function and Effective Workouts01:20:49 Where to Find Dr. Phil Batterson01:24:13 VO2 Max Testing and Interpretation01:28:42 Challenges in Lactate Threshold Testing01:39:00 Dynamic Range and Performance01:44:59 Conclusion and Final ThoughtsFlex Diet Podcasts You May Enjoy: Episode 264: Finding Your Aerobic Sweet Spot for Peak Health with Dr Phil BattersonYouTube: https://youtu.be/5j90cmi_I6k Episode 275: Mastering Combat Sports Conditioning Using Advanced Training Techniques with Strength Coach James TognariniYouTube: https://youtu.be/t9Hc-VrsY4kConnect with Dr Phil Batterson:Instagram: https://www.instagram.com/drphilbatterson/Get In Touch with Dr Mike:Instagram: DrmiketnelsonYouTube: @flexdietcertEmail: Miketnelson.com/contact-us
