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.
