    How to Harness Leucine and EAA for Bigger Muscles and More — Daniel A. Traylor, Ph.D. — #392

    Can you really build more muscle just by rethinking how you dose leucine and essential amino acids? Dr. Daniel A. Traylor, Ph.D. — co-founder and principal scientist of LEUVATE™ — reveals the science behind protein quality, muscle protein synthesis, and why older adults may need twice the protein dose to get the same results as younger people. We dig into mTORC1 signaling, sarcopenia, the 30g protein absorption myth, GLP-1 drug effects on muscle, and the clinical trial data behind LEUVATE™. If you care about muscle, longevity, or protein strategy, this one is loaded. Guest Bio Daniel A. Traylor, Ph.D. is an Assistant Professor of Health Sciences at DePaul University in Chicago and Owner, Co-Founder, and Principal Scientist of LEUVATE™. His research explores how protein quality, amino acids, and exercise interact to influence muscle adaptation, recovery, and physical function across the lifespan. He is the co-inventor of LEUVATE™ — a precision-engineered leucine-enriched nutritional formula validated across multiple peer-reviewed human clinical trials. Timestamps 3:36 — Can you really only absorb 30g protein at once? 9:16 — Sarcopenia: the muscle-loss crisis in aging 16:01 — mTORC1 and what triggers muscle protein synthesis 20:46 — Why older adults may need twice the protein dose 30:26 — The origin story of LEUVATE™ 34:01 — Leucine: the master switch for MPS 37:56 — How leucine acts as a dimmer on mTORC1 53:21 — GLP-1 drugs, muscle loss, and amino acid needs 1:06:36 — LEUVATE™ vs whey: MPS data and ongoing trials 1:17:01 — How leucine-enriched EAAs signal differently in the gut 1:27:11 — Protein spiking and supplement quality red flags Resources LEUVATE™ Dr. Traylor email Get the Daily Fitness Insider newsletter (free): https://www.miketnelson.com/newsletter

    Flex Diet Cert Closes at Midnight Mon 6/22/2026 and Coaching Leverage — #391

    In this solo episode, Dr. Mike T. Nelson introduces the concept of coaching leverage—the idea that effective coaching means multiplying physiological impact by a client's realistic ability to change. Why sleep is a physiological powerhouse but a coaching nightmare The coaching leverage formula: physiology × psychology Why protein ranks #1 (score: 81) and sleep ranks #8 (score: 20) How to stop majoring in the minors with your clients The eight interventions inside the Flex Diet Certification Why following a proven system beats reinventing the wheel The Flex Diet Certification closes tonight (Monday, June 22, 2026) at midnight Pacific.

    Antibiotics, Gut Microbiome, and the Exercise Connection — Dr. Sara Campbell — #390

    In this episode of the Flex Diet Podcast, I sit down with Dr. Sara Campbell, Ph.D., Associate Professor at Rutgers University, for a conversation about the bidirectional relationship between exercise and the gut microbiome. Dr. Sara Campbell returns to discuss her lab's cutting-edge research on the bidirectional relationship between exercise and the gut microbiome — including why consumer gut tests oversimplify a complex ecosystem, how antibiotics devastate exercise capacity in animal models, and why single-microbe probiotics miss the bigger picture of functional guilds. She also shares new findings on short-chain fatty acids, amino acid metabolomics after antibiotic treatment, and the emerging neuromuscular junction hypothesis. In this episode you'll learn: Why consumer gut microbiome tests are misleading and what functional guilds tell us instead How antibiotics devastate exercise capacity and the surprising metabolomic changes they cause The current evidence on probiotics for exercise performance and why single strains fall short What short-chain fatty acids do for gut health and exercise, and the emerging neuromuscular junction hypothesis Find Sara here:Rutgers Faculty Page Google Scholar: Sara Chelland Campbell --- The Flex Diet Podcast is brought to you by the Flex Diet Certification.

    The Flex Diet Cert is OPEN and AI vs Coaching Solocast — #389

    In this solo episode, Dr. Mike T. Nelson dives into the intersection of AI and coaching. Using his quest to pick up the 175-pound Inch dumbbell as an example, he shows how AI struggles with niche topics where quality training data is scarce — and why that matters for fitness advice. Topics covered: Why AI gave terrible advice on training for the Inch dumbbell — and what that reveals about how AI sources information The protein-and-kidney-damage myth: when AI repeats bad science Where AI actually helps coaches: data analysis, blood work organization, backend tasks, and production workflows Why clients still want (and need) a real human coach — accountability, customization, and skin in the game Will people be compliant to a robot coach? Probably not The baseline is rising: why just writing training and nutrition programs isn't enough anymore Flex Diet Certification — now open through Monday, June 22nd, 2026 at midnight PST. Eight interventions (protein, fats, carbs, exercise, sleep, micronutrition, fasting, and more) built on coaching leverage and metabolic flexibility.

    What Vinegar & Lifting Really Do To Your Gut — Dr. Emily Dow — #388

    Dr. Emily Dow, PhD, RD, is a researcher and registered dietitian working at the intersection of nutrition, resistance training, and gut health. Does vinegar actually do anything for your gut or your blood sugar? Can you trust a $200 mail-in microbiome test? Emily built her dissertation around questions like these, and her honest answers are a lot more useful than the marketing. Expect to learn what a 12-week resistance-training-plus-vinegar protocol did (and didn't do) to gut permeability, why a null result in a healthy population is still worth your attention, what the research really says about vinegar and glucose control, why the peptide boom warrants a hard dose of skepticism, what direct-to-consumer gut testing genuinely can and can't tell you, the underrated role stress plays in GI symptoms, and why the best practitioners do both research and hands-on coaching — and much more. — Get the Daily Fitness Insider newsletter (free): https://www.miketnelson.com/newsletter Connect with Dr. Dow: Website: https://www.dremilydow.com Instagram: https://www.instagram.com/dremilydow Episodes you'll enjoy next: #127 — The Effect of Antibiotics on Muscle Mass & Cardiovascular Performance with Dr. Sara Campbell: https://flex-diet-podcast.simplecast.com/episodes/episode-127-the-effect-of-antibiotics-on-muscle-mass-aerobic-cardiovascular-performance-and-more-an-interview-with-dr-sara-campbell #222 — Nutrition, Supplements & Training with RD Sean Casey https://flex-diet-podcast.simplecast.com/episodes/episode-222-expert-insights-on-nutrition-supplements-and-training-with-registered-dietician-sean-casey Enjoying the show?

    Episode 387: Nathan T. Jenkins on Metabolic Flexibility, Aerobic Base, and First Principles

    In this episode of the Flex Diet Podcast, I sit down with Dr. Nathan Jenkins to discuss how to improve performance, body composition, and long-term health through the lens of aerobic development and metabolic flexibility. Nathan shares his journey from exercise physiology and coaching CrossFit athletes to his new role teaching physiology at the University of Georgia School of Medicine. We discuss why metabolic flexibility is such a powerful framework for understanding everything from biochemistry and exercise performance to metabolic disease. We also dive into interpreting maximal exercise testing data, including VO₂ measurements, EKG analysis, and near-infrared spectroscopy (NIRS), along with how different energy systems work together during training and competition. Nathan explains why building an aerobic base is critical for repeated high-intensity performance, how pacing impacts outcomes, and why the ability to "suffer" is actually a trainable skill. To wrap up, we cover practical strategies you can apply right away, including prioritizing protein and carbohydrates, improving sleep quality, and addressing common micronutrient deficiencies through blood work, such as magnesium, vitamin D, and omega-3 status.

    Episode 386: Nervous System Regulation, Somatics, and Stress Resilience with Tracy Holemeyer

    In this episode of the Flex Diet Podcast, I sit down with my friend Tracy Holemeyer (Uncontrollably Me, host of the Other Way to See It podcast) to talk about healing and performance through nervous system flexibility, somatics, and self-awareness, especially with how much stress people are carrying right now.  We dig into practical tools like orienting, grounding, the “starfish” drill, pendulation, and Tracy’s “core four” (soft eyes, relaxing the tongue, breath pacing for coherence, and soft knees), plus how posture and unconscious habits can shape mood and behavior. We also explore the value of community and coaching, how movement and sound (including humming, voo breath, and growling) can help regulate, and we finish with a thoughtful discussion on psychedelics, integration, and why support and discernment matter.

    Episode 385: Rob Wilson on BJJ Performance Frameworks, Grip Training, Recovery Tech & The Check Engine Light Book

    In this episode of the Flex Diet Podcast, I sit down with human performance specialist and coach Rob Wilson for a wide-ranging conversation that spans music, coach education, and what it really means to train for performance longevity. We dig into Rob’s new book, The Check Engine Light: Tune In Your Body and Mind to Achieve Performance Longevity, and his work educating coaches through ALTIS and with special operations communities. Rob also shares why jiu-jitsu strength and conditioning still lacks clear performance standards and proposes building sport-specific frameworks (like lower-body clinching demands) before jumping to exercise selection. We talk grip strength vs endurance, avoiding redundancy and tendon issues, contra-specific training for durability, and why “recovery” isn’t the goal—adaptation is—especially in elite sport.
