Episode #185: Is Cortisol Good Or Bad?

Full Show Notes: https://bengreenfieldlife.com/lnraw06/ Welcome to RAW—my unfiltered solo podcast (hosted on LIFE Network), where you get the real, behind-the-scenes version of my life: the biohacking experiments I’m running on myself, the protocols I’m building and breaking, the tools and tech I’m stress-testing before anyone hears about them, the ideas in physiology, performance, and longevity I’m diving into, the beliefs I’m questioning, the routines I’m refining, and the unconventional stuff I’m actually doing day to day—no gloss, no script, just a direct line into what I’m thinking, testing, discovering, and living in real time. In this episode, we go deep into the “RAW” terrain of jaw mechanics—think controversial, awkward, and a tad nerdy, but game-changing for health. It all starts at a cocktail party when a Sherlock Holmes-style dentist spots red flags just by looking at his mouth. Cue a year-plus journey into bioesthetic dentistry, mindfully chewing food, and mastering “mewing” (tongue and jaw posture that even changes your face shape). What’s the big actionable win? Stop ignoring your mouth! Rethink your mechanics, posture, and oral hygiene—ditch the fluoride, embrace hydroxyapatite toothpaste, train your tongue to suction to your palate, and breathe through your nose like a pro. Bonus: mouth taping is not just for sleep geeks. Episode Sponsors: Just Thrive: Take the Just Thrive FEEL BETTER challenge today, and save 20% on your first Gut Essentials Bundle.

Full Show Notes: BenGreenfieldLife.com/nicknorwitz In this episode with Dr. Nick Norwitz, you’ll get to discover how a Harvard-trained MD/PhD used a simple, eyebrow-raising experiment with Oreos to challenge conventional thinking on cholesterol, metabolism, and the stories told about health. We dive into his now-viral “Oreo experiment,” where adding Oreos to a ketogenic diet dropped his LDL cholesterol faster and more effectively than a high-intensity statin—an unexpected outcome that opens the door to deeper questions about lipid markers, risk factors, and how the body actually processes dietary fats. Nick Norwitz MD PhD is a researcher-educator whose mission is to “Make Metabolic Health Mainstream.” He graduated Valedictorian from Dartmouth College, majoring in Cell Biology and Biochemistry, before completing his PhD in Metabolism at the University of Oxford and his MD at Harvard Medical School. Nick has made a name for himself as a clinical research and metabolic health educator, speaking and writing on topics ranging from brain health, the microbiome, mental health, muscle physiology, mitochondrial function, cholesterol and lipids, and so on.
