Flex Diet Podcast

In this episode of the Flex Diet Podcast, I catch up with my good friend Jason Brown to dig into the intersection of strength training and aerobic development. We talk through how to implement aerobic conditioning in the real world, what zone two training actually is (and isn’t), and the pros and cons of different training methodologies. Jason shares his thoughts on concurrent training, functional movement, and how to improve performance without sacrificing long-term health. We also get into the realities of online coaching and how to structure training programs that support sustainable progress over time. If you’re looking to improve body composition, build muscle, and boost performance within a flexible, evidence-based framework, this episode will give you plenty to work with.Sponsors:Rogue: https://miket.me/rogueBeyond Power Voltra 1: https://www.beyond-power.com/michael13Meathead Cardio Course Level 1: Aerobic System https://miket.me/cardioFitness Insider Newsletter: https://miketnelson.com/Episode Chapters:04:26 Jason Brown Introduction and Background04:58 Transition to Online Training07:16 Challenges and Adaptations in Online Coaching15:01 Assessment and Customization in Training19:46 Importance of Aerobic Conditioning21:38 Heart Rate Monitoring and Technology32:36 Debunking Myths and Misconceptions40:13 Personal Training Evolution40:29 Aerobic Training Benefits40:56 Training Philosophy and Methods41:54 Zone Two Training Debate43:23 Stress and Training Adaptations44:24 Creative Conditioning Approaches57:02 Concurrent Training Insights01:04:26 Programming and Practical Experience01:14:36 Final Thoughts and RecommendationsEpisodes You Might Enjoy:Episode 326: Row Hard, Breathe Easy: Boosting Aerobic Capacity with Dr. Kenneth JayYouTube: https://youtu.be/hpvKokMBRv4?si=sL-dFZ2reY_W5RWVEpisode 335: Grip, Guts & Gas Tanks: Aerobic Training for Meatheads with Levi EarlYouTube: https://youtu.be/S13JxU57-sk?si=phRGaQSaN0SnXnsOConnect with Jason:Website: https://www.jasonbrowncoaching.com/YouTube: https://www.youtube.com/@jasonbrowncoachingInstagram: https://www.instagram.com/jasonbrowncoachingGet 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 my good friend Aram Grigorian from the Real Coaches Summit to talk shop on what actually matters in coaching today. We dig into body composition and weight loss, why consistency still beats novelty, and how to think more clearly about calorie tracking without losing the forest for the trees.We also get into industry trends, client compliance, and why live, in-person events remain one of the most underrated tools for becoming a better coach. If you’re a trainer or just serious about improving your health and results, this is a practical, no-nonsense conversation you’ll get a lot out of. I also share a sneak peek at what’s coming up at the Real Coaches Summit.WARNING – you may be offended by some items that Aram or I say in this podcast.

In this episode of the Flex Diet Podcast, I sit down with Dr. Lauren Colenso-Semple to cut through the noise and tackle some of the most persistent myths in women’s fitness. We break down where misinformation shows up in popular programs, why overly complicated plans often backfire, and what the science actually says about fasted training and low energy availability. We also get into hot topics like cold water immersion and cortisol, real sex-based differences in training responses, and why women’s fitness research is still so challenging to conduct well. If you’re looking for practical, evidence-based guidance instead of hype, this episode will help you train smarter and with more confidence.Sponsors:LMNT: http://drinklmnt.com/mikenelson (automatically applied at checkout)Beyond Power Voltra 1: https://www.beyond-power.com/michael13Fitness Insider Newsletter: https://miketnelson.com/Episode Chapters:04:30 Interview with Dr. Lauren Colenso-Semple05:01 Complications in Women's Fitness07:39 Effective Training Strategies18:42 Fasted Training for Women23:33 Low Energy Availability28:50 Cold Water Immersion for Women34:27 The Overemphasis on Recovery36:45 Sex-Based Differences in Training37:04 The Fiber Type Debate43:41 Genetics and Athletic Performance46:23 Women's Specific Supplements53:50 Challenges in Women's Fitness Research01:00:51 Rapid Fire Questions and ConclusionEpisodes You Might Enjoy:Episode 267: Demystifying Women’s Fitness and Nutrition with Alli FahrenbachYouTube: https://youtu.be/w13NXowjSVU?si=QDdKNRGZZq_SgT5hEpisode 296: Enhancing Athletic Performance with Dr. Dani LaMartinaYouTube: https://youtu.be/ts_eqvs6OI4?si=TiqFPjcsxI9a3owFConnect with Dr Lauren Colenso-Semple:Website: https://www.drlaurencs.com/Instagram: https://www.instagram.com/drlaurencs1Get In Touch:Instagram: https://www.instagram.com/drmiketnelson/YouTube: https://www.youtube.com/channel/UCn1aTbQqHglfNrENPm0GTpgEmail: https://miketnelson.com/contact-us/

Welcome back to the Flex Diet Podcast! Today, I’m hanging out with the brilliant Katie Emerson, Senior Manager of Scientific Affairs over at Kyowa Hakko USA, aka the people behind Cognizin (CDP Choline), one of the few brain-boosting ingredients with legit research behind it.We dig into the real science of CDP Choline, how it supports memory, focus, and cognitive performance, and where it actually fits into the human physiology engine, not the hype machine. Katie and I also zoom out into the supplement industry as a whole, chatting about what’s worth paying attention to, what’s still emerging, and how to navigate all the shiny promises out there.We even take a nerd-tour into mental resilience, genetic mapping, and the surprising potential of glutathione for health and performance.If you’re curious how targeted supplements can help you think faster, recover better, and be a more high-performing human without needing a PhD to decode marketing nonsense, this episode is for you.Sponsors:Flex 4: Katie's top 4 things to know about citocholineEpisode Chapters:03:52 Katie Emerson Joins the Conversation04:09 Conversations at ISSN and Networking11:20 Research and Studies on CDP Choline17:49 Challenges in Supplement Formulation24:40 Mechanisms and Benefits of CDP Choline28:06 Exploring Genetic Mapping and Data Overload29:01 Study Design and Dosing Strategies30:29 The Sweet Spot of CDP Choline Dosage33:40 Pharmacokinetics and Timing of CDP Choline35:36 Safety and Side Effects of High Doses38:59 Comparing CDP Choline and Alpha GPC42:41 Introduction to Glutathione48:41 Oral Absorption of Glutathione52:12 Podcast Conclusion and Listener Information Episodes You Might Enjoy:Episode 343: Fueling the Corporate Athlete: Stress, Supplements & Performance with Dan Hunter YouTube: https://youtu.be/0ek4XSs62RQ Episode 222: Expert Insights on nutrition, supplements, and training with Registered Dietitian Sean CaseyYouTube: https://youtu.be/wjJB-y1kwgMConnect with Katie:Cognizin: cognizin.comGet In Touch:Instagram: https://www.instagram.com/drmiketnelson/YouTube: https://www.youtube.com/channel/UCn1aTbQqHglfNrENPm0GTpgEmail: https://miketnelson.com/contact-us/

I also break down how physiologic flexibility ties it all together for next-level performance and recovery.If you’re into cutting-edge performance science, brain optimization, or just want to hear two nerds talk physiology and Navy SEAL mental toughness, this one’s for you.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:07:30 Interview with Dr. Blaine Lints Begins08:20 Research on Caffeine and Theacrine22:12 Dr. Lints' Ironman Journey34:23 Exploring Ketones and Heat Stress52:56 Exploring Ketone Esters and Their Benefits53:52 Personal Experiences with Ketone Dosages55:28 Research Insights on Ketone Mono Esters57:34 Ibogaine Study for Special Operators01:00:12 Personal Journey with Ibogaine Treatment01:04:23 Potential of Psychedelic Medicines01:10:26 Safety and Legality of Psychedelic Treatments01:18:56 Future of Psychedelic Research and Applications01:26:32 Conclusion and Final ThoughtsFlex Diet Podcasts You May Enjoy: Episode 311: Maximizing Athletic Performance with Neurology: Insights from Dr. Dylan SeeleyYouTube: https://youtu.be/bnuYQ-GJ6to. Episode 167: The Physiologic and Psychologic Benefit of Doing Hard Things: Akshay Nanavati of Fearvana with Dr Mike T NelsonYouTube: https://youtu.be/G_iFVGHZSEsConnect with Blaine:Instagram: https://www.instagram.com/blaineketsGet In Touch with Dr Mike:Instagram: DrmiketnelsonYouTube: @flexdietcertEmail: 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

On this week’s Flex Diet Podcast, I sit down with Angelo Keely, co-founder of Kion, to geek out on all things essential amino acids (EAAs). We’ll dig into the nitty-gritty science and—more importantly—what that means for you in the real world.Want to pack on more muscle? Drop some fat without feeling wrecked? Stay strong and sharp as the years tick by? EAAs can help—if you know how to use them. We’ll break down why they’re not just “protein lite,” how they work differently than your standard whey shake, and the smartest ways to add them into your nutrition strategy.If you care about muscle, performance, or aging like a badass, this one’s worth a listen.Sponsors:Kion EAAs: https://www.getkion.com/collections/drmikeAvailable now:Grab a copy of the Triphasic Training II book I co-wrote with Cal Deitz here.Episode Chapters:01:30 – Meeting Angelo Keely at ISSN03:00 – Essential Amino Acids: What Are They?06:00 – Protein vs. EAAs vs. BCAAs09:30 – The Science of Protein Synthesis13:00 – Muscle Gain, Body Composition, and Aging17:00 – EAAs for Fat Loss and Caloric Restriction21:00 – Research on EAAs and Muscle Preservation25:00 – Supplement Quality: What to Look For28:00 – How to Use EAAs: Dosing and Timing32:00 – EAAs for Older Adults and Special Populations36:00 – Taste, Formulation, and Product Differences40:00 – Practical Tips for Athletes and Everyday Use44:00 – Creatine vs. EAAs: Which to Choose?47:00 – Real-World Experiences and Anecdotes50:00 – Q&A and Final ThoughtsFlex Diet Podcast Episodes You May Enjoy: Episode 291: Anabolic Strategies and Nutrition Tips to Maximize Muscle Growth & Health with Dr David ChurchYouTube: https://youtu.be/VudpMeB_33w Episode 274: How Muscle Fibers Influence Metabolism: Insights from Nathan SerranoYouTube: https://youtu.be/Ul2TOiodgaoConnect with Angelo:Instagram: https://www.instagram.com/angelokeelyKion: https://www.getkion.comGet In Touch with Dr Mike:Instagram: DrmiketnelsonYouTube: @flexdietcertEmail: Miketnelson.com/contact-us
