    Episode 373: The Future of Fitness + Healthcare: Coaches, Blood Work, and Client-Centered Models | Kevin Dineen

    In this episode of the Flex Diet Podcast, I sit down with coach Kevin Dineen to talk about where fitness and healthcare are headed and whether their merger is a net positive or negative. We dig into why people still default to asking physicians about training and nutrition, the problems created by siloed systems, and what a more client-centered model could look like with coaches, PTs, massage therapists, and physicians collaborating under one roof. 

    We also discuss the pros, cons, and liability concerns around coaches using blood work for performance, how hard training can skew lab results, and why basic habits like lifting, cardio, steps, and community support matter more than expensive supplement stacks. Kevin closes with key advice for newer coaches: professionalism, mentorship, travel to learn standards, and clarifying your “why.”

    Episode 372: PCOS Made Practical, Body Recomp Basics, and the Wild West of Peptides (w/ Dr. Ashley Dwyer)

    In this episode of the Flex Diet Podcast, I sit down with Dr. Ashley Dwyer, a PharmD-turned nutrition and fitness coach, to cover a wide range of topics, with a strong focus on PCOS (polycystic ovarian syndrome), a metabolic condition that affects fertility, cycles, and systemic health. 

    We dig into practical lifestyle strategies for insulin-resistant PCOS, including balanced meals, protein and fiber, blood sugar management, movement, and stress reduction, plus why long-term keto often isn’t a great fit. We also discuss GLP-1 medications, including concerns about HRV and resting heart rate, and why foundations and coaching matter when someone uses them. 

    Finally, we discuss the current “wild west” of peptides, the lack of human data, dosing and purity issues, and the importance of transparency, consistency, and identity-based behavior change for body composition and long-term health.

    Episode 371: Peptides, TRT, GLPs & Bloodwork: How to Do It Safely (and What Most People Miss) with John Gorman

    In this episode of the Flex Diet Podcast, I sit down with my good friend John Gorman to unpack the current “wild west” of peptides, TRT, GLP medications, and performance-driven bloodwork.

    We dig into how John’s telemedicine clinic approaches comprehensive lab testing — and why running a full panel (including markers like reverse T3) matters far more than cherry-picking a few numbers. If you’ve been dieting hard, training consistently, and still feeling stuck, we break down how chronic stress, poor recovery, and subtle hormone disruptions can quietly crush metabolism and make fat loss feel like a white-knuckle grind.

    We also cover testosterone replacement therapy (TRT) — the real pros and cons, common oversimplifications in the industry, and what most clinics fail to discuss. From there, we dive into GLP-1 medications and tirzepatide, what we currently know, what we don’t know about long-term use, and how to think critically about risk versus reward.

    John shares practical guidance on legitimate peptide sourcing, red flags to watch for, and how to think about “periphery” tools like methylene blue and injectable carnitine without getting sucked into hype.

    If you’re interested in optimizing performance, improving body composition, or simply making smarter decisions in a rapidly changing medical landscape, this episode will help you separate signal from noise.

    Episode 370: Hybrid Training Done Right: Building Strength & Endurance Without Killing Your Gains with Andreas Stobberup

    In this episode of the Flex Diet Podcast, I sit down with Denmark-based coach and hybrid athlete Andreas Stobberup to talk about bridging serious strength training with high-level endurance performance.

    Andreas shares his journey from peaking around 250 lbs with a 405 bench and 600+ squat to dropping to 205 and completing a full Ironman in 9:52—while continuing to coach athletes across disciplines. We discuss the reality gap between amateur and elite performance, how influencer culture often strips context from training advice, and why fundamentals still win: training, nutrition, sleep, and measurable outputs.

    We break down common misunderstandings around Zone 2 training, why pros don’t train the way social media says they do, and how strength athletes can intelligently add conditioning without compromising lifting. We also cover VO₂ max development, microdosing cardio, output-based tracking (times, power, lactate), and how to think about HRV and wearable data in context.

    If you’re interested in hybrid training, improving conditioning without sacrificing muscle, or understanding how to measure what actually matters, this one is packed with practical insight.

    Episode 369: Stop “Thinking Positive”: Nervous System, Pressure, and Performance with Vince Malts

    In this episode of the Flex Diet Podcast, I sit down with my good buddy Vince Maltz, a high-performance mindset coach who works with NHL players, Division I athletes, and elite performers. We dig into what “mindset training” actually looks like in real life, beyond the clichés, and why it’s inseparable from physiology, recovery, and nervous system regulation.

    We also get into the modern performance environment: fake expertise, too many voices in the kitchen, and why big organizations adapt slowly. Vince breaks down centralized vs. decentralized leadership, how athletes can learn to think for themselves inside a system, and why being a “nerd” at your sport is becoming a competitive advantage. 

    From there, we hit practical tools: how athletes move from conscious competence to unconscious competence faster, why distributed cognition matters in team sports, and what individuals can do today to improve performance through breathing, cold exposure, communication, and environment.

    Episode 368: Why NEAT (Step Count) Might Be the Missing Key to Fat Loss, Recovery, and Performance & Flex Diet Cert Closes Tonight

    In this solo episode of the Flex Diet Podcast, I break down why NEAT (non-exercise activity thermogenesis), and a simple step count, is one of the most overlooked levers for improving body composition, recovery, and performance. I explain how NEAT often drops when calories are reduced, why that can stall fat loss even when you think you’re in a deficit, and how using wearables (or even basic tracking) can make subconscious movement visible and easier to improve. 

    I also share how the Flex Diet Cert is built as a complete system for nutrition and recovery, covering interventions from macros (protein, fats, carbs) to NEAT, sleep, micronutrition, intermittent fasting, and more — designed for everyone from general population clients to high-level athletes. 

    I also remind listeners that enrollment for the Flex Diet Cert closes Monday, February 16th, 2026, at midnight Pacific.
