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 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/

On this episode of the Flex Diet Podcast, I sit down with my good buddy and lab-coat-wearing performance wizard, Dr. Andrew Koutnik. We talk about how to boost muscle performance, improve body composition, and feel like an athletic human without dumpster-firing your health.We dig into cold water immersion (and when it can kick gains in the shins), blood glucose regulation, ketogenic diets, carbs (yes, they’re still awesome), and how to build metabolic flexibility that actually translates to better outcomes in the gym and life.Andrew shares some killer insights from his research at Florida State University, especially around keto diets and athletic performance. If you’re curious about whether low-carb can help or hurt your performance, this is your jam.If you want practical tools for a bigger physiological engine, tune in!Sponsors:Tecton Ketones: https://tectonketones.com/LMNT:  http://drinklmnt.com/mikenelson (automatically applied at Episode Chapters:05:28 Conferences and Networking08:34 The Importance of Practical Application in Science21:43 Cold Water Immersion and Stress Responses32:53 Mindfulness and Meditation39:29 Blood Glucose and Exercise Performance52:00 Limitations of Association Studies in Sports Performance52:47 Impact of Blood Glucose on Performance57:04 Historical Perspective on Ketogenic Diets01:00:52 Study on Ketogenic Diets and Ironman Competitors01:15:53 Health Implications of High Carbohydrate Diets01:18:48 Concluding Thoughts on Nutrition and Performance Episodes You Might Enjoy:Episode 254: Exploring the Frontiers of Ketone Science and Brain Health with Mike Chesne from Tecton LifeYouTube: https://youtu.be/uTsM_ETF8Us Episode 253: Enduring the Antarctic Chill and Unveiling the Power of Ketones with Akshay Nanavati and Tecton LifeYouTube: https://youtu.be/ockRFjBiOQcConnect with Dr Koutnik:Website: https://andrewkoutnik.com/Instagram: https://www.instagram.com/andrewkoutnikphd/Get In Touch:Instagram: https://www.instagram.com/drmiketnelson/YouTube: https://www.youtube.com/channel/UCn1aTbQqHglfNrENPm0GTpgEmail: https://miketnelson.com/contact-us/
