In this episode of the Flex Diet Podcast, I sit down with Dr. Jeremy Bettle, a performance director and applied sports scientist, to dig into what actually moves the needle for performance, recovery, and long-term resilience.
We cover everything from high ankle sprains and injury prevention to smarter load management, and why understanding stress, recovery, and tissue capacity matters far more than chasing random training trends.
Dr. Bettle shares insights from years of work across the NHL, NBA, and international sport, along with how elite performance systems can — and should — be translated to non-elite humans who want to train hard, recover better, and keep doing this for decades.

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.

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. Just a heads-up, and enjoy.

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.

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.

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.

In this episode of the Flex Diet Podcast, I sit down with my good friend Dr. Tommy Wood to dig into his upcoming book, The Stimulated Mind — a ridiculously practical guide to building a better brain.
We get into all kinds of fun rabbit holes: how technology is changing fitness, why lactate (yes, the same stuff you curse during hard intervals) is actually rocket fuel for your brain, and why a solid dose of cardio is one of the most underrated cognitive enhancers out there.
We also tackle resistance training, neuroplasticity as you age, and which sports and drills actually move the needle for cognition. And because it’s Tommy, we even wander into the spicy territory of psychedelics and whether they may have a place in brain health.
If you want real, actionable strategies to boost memory, focus, and long-term cognitive performance—without drowning in jargon—this episode is for you.
Tune in and geek out with us.

In this episode of the Flex Diet Podcast, I sit down with Dr. Jeff Rouse from Shiftwave to talk about his mind-bending device that claims to reset your nervous system.
I’ll be honest, when I first saw it, I was skeptical. But after trying it at the Parker University conference, I was blown away by what it did. We dig into how the tech works, why it’s so effective for both physical and mental health, and how it’s being used everywhere from mental health therapy to pro sports.
Dr. Rouse brings a fascinating mix of psychiatry, quantum biology, and wellness tech expertise to the conversation. He explains the science behind Shift Wave, the principles that make it tick, and some of its wildest protocols, like “synthetic sleep.”
If you’re into cutting-edge tools that help you recover faster, feel better, and perform at your best, this one’s worth the listen.
