Flex Diet Podcast

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!

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.

In this episode of the Flex Diet Podcast, I sit down with my good friend Dr. John Rusin to dig into his new book, Pain-Free Performance: Move Better, Train Smarter, and Build an Unbreakable Body. We talk all things movement, strength, and longevity—how to actually perform at a high level without wrecking yourself in the process. John drops some serious wisdom from decades of training and coaching, and we get into the real science behind balancing load, recovery, and pain management so you can keep crushing it for the long haul. If you want to know how to train hard, move well, and build a body that lasts, you’ll definitely want to tune in.

In this episode of the Flex Diet Podcast, I sit down with my good friend Dr. Dan Pardi for a deep dive into all things health, longevity, and cognitive performance. We get into the science of stem cells and aging, the real benefits (and limits) of popular supplements, and how nootropics like Ritalin and Modafinil actually work—or don’t—in the real world. We also talk about how to integrate training and movement into insanely busy lives, the psychology of health behavior, and why being flexible in your approach (not just in your hamstrings) is key to long-term success. This episode is brought to you by Quaia Life, where Dan’s doing some fascinating work on cutting-edge supplements designed to optimize health and performance. They’re offering listeners 15% off their products, which you can grab through the link in the show notes. If you want a mix of actionable tips, science-backed insights, and a peek behind the curtain of how top researchers think about performance and aging, you’ll definitely want to tune in.
