Ben Greenfield Fitness: Diet, Fat Loss And Performance

Full Show Notes: bengreenfieldlife.com/stimulatedmind In this episode with Dr. Tommy Wood, you'll explore what actually determines how well your brain functions across your entire lifespan, from the inputs that drive cognitive development in infancy all the way through the habits, environments, and daily choices that either accelerate or protect against decline in adulthood and old age, all grounded in the research behind his new book, The Stimulated Mind: Future-Proof Your Brain from Dementia and Stay Sharp at Any Age.  You'll discover why the modern world leaves you simultaneously overstimulated by technology and understimulated in the ways that actually build cognitive capacity, why lactate from intense exercise may be one of the most underrated brain health tools you have, and which types of exercise target different parts of the brain. Dr. Wood also gets personal on his own diet and supplement stack, breaks down what AI is actually doing to your cognitive capacity, and gives his honest take on alcoh

Full Show Notes: bengreenfieldlife.com/fmt In this episode, you'll get to uncover one of the most intriguing developments in gut health—fecal microbiota transplants (FMTs). Joining me is Jason Klop, CEO of Novel Biome, who brings cutting-edge insight into how FMT is transforming from an obscure, hospital-based procedure into an accessible, precise, and surprisingly simple tool for optimizing your microbiome at home. We’ll break down how FMT is now being used for everything from irritable bowel issues to food sensitivities, and why the technology has advanced well beyond its origins. You'll also hear about the meticulous screening behind “super donors,” the science of oral FMT capsules, and the real-world results you can expect—including my own personal experience. Whether you’re looking to boost your gut health, support your immune system, or simply curious about the connection between your microbiome and overall vitality, this episode has what you need to stay on the cutti

Full Show Notes: bengreenfieldlife.com/magteinpodcast In this episode with neuroscientist Dr. Guosong Liu, you’ll explore his accidental discovery at MIT's Center for Learning and Memory that led him down a two-decade journey into brain magnesium, synaptic plasticity, and cognitive decline. That research ultimately resulted in the invention of Magtein® (magnesium L-threonate), a compound he engineered to cross the blood-brain barrier in a way other magnesium forms cannot, with clinical trials showing a reversal of nine years of cognitive decline, measurable shifts in sleep architecture, stress reduction in as little as three days, and meaningful improvements in prefrontal cortex function at just 140 milligrams per day. Dr. Liu also shares what his current Alzheimer's prevention research looks like. Dr. Liu is a world-renowned neuroscientist whose pioneering research on brain magnesium has transformed our understanding of cognitive function and synaptic plasticity. With more than 25 years of neurosci

Full Show Notes: bengreenfieldlife.com/ways2well In this episode, I sit down with Brigham Buhler at Ways2Well in Austin, Texas, exposing the "sick care" maze, including insurance company middlemen, skyrocketing drug prices, and the rebate system nobody talks about. This is what optimizing your health actually looks like: not managing disease, not waiting for a diagnosis, but getting inside the lab and taking control. Brigham Buhler is a healthcare entrepreneur, founder of Ways2Well, and owner of ReviveRX. He spent years inside the systems he now fights against, working across pharmaceutical sales and sports medicine before building a cash-pay alternative to the insurance model.  Ways2Well is a clinician-led health company built around continuous, personalized care. They combine advanced diagnostics, expert interpretation, individualized treatment plans, and regenerative therapies to help patients understand what's actually happening in their bodies, rather than solely treating symptoms.  Ready to ta

In part 2 of the Identity Inversion series, I walk you through the full exercise I completed during an 8-hour personal retreat—2 hours each morning across 4 days—revealing the blind spots, weaknesses, and patterns I identified in my own life and the single words I'm using to redraw my identity. You’ll learn about everything from my impatience with imperfection to my fear of trying new things as I age.

Full Show Notes:  bengreenfieldlife.com/lnraw04 Welcome to RAW—my unfiltered solo podcast, hosted on LIFE Network (which is completely free to join here—you can listen to every RAW episode plus a full library of health and wellness podcasts, including Boundless Life). RAW is where you get the real, behind-the-scenes version of my life: the biohacking experiments I’m running on myself, the protocols I’m creating, 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. In this episode, I open up about one of the most powerful anchors in my family's life—our daily bookends. These are the routines my family and I use to start and end each day with intention, connection, and purpose. I walk you through our morning huddle, where we check in, talk sche

*In this episode, you'll discover a three-step framework for exposing the unconscious patterns quietly running your life and learn exactly how to flip each one.* ## Episode Summary In this episode, I introduce a very helpful life transformation framework called “Identity Inversion.” It's a simple exercise I designed (based on my own self-experimentation!) for identifying unconscious patterns, habits, and identity traps that are keeping you from becoming the best version of your broken self. Using two relatable examples (a man addicted to the gym for self-worth and a woman addicted to productivity for approval), I’ll walk you through a three-step process: describe the pattern in a paragraph, name its redemptive opposite in a sentence, then distill it into a single word that becomes the key to redrawing your identity. Next week, so you can get a really concrete idea of what this looks like, I’ll share my own 10 identity inversions. ## Question of the Day

Full Show Notes: bengreenfieldlife.com/498 In this solosode I kick off by talking about whether isometric training is worth your time, covering both my own fitness habits and the newest research, particularly for runners and joint health. I also unpack a buzzworthy study on how just 10 minutes of vigorous exercise daily can be a powerful longevity booster compared to longer, lighter workouts. I share why I no longer personally use metformin, and instead, offer my favorite natural alternatives for better blood sugar control—like berberine, fiber, cinnamon, and simple routines like salads and walks. Plus, I get into brain health, explaining the roles of ketones, methylene blue, and near-infrared light for cognitive performance and protecting against issues like Alzheimer’s. At the end, I answer listener questions on optimizing DHT levels, natural insulin-sensitizers, and keeping your hair healthy even if you’re on testosterone.

Full Show Notes: bengreenfieldlife.com/hungercode On this episode, I got to geek out with Dr. Jason Fung and unravel why calorie counting alone doesn’t explain our weight struggles. Dr. Fung used jaw-dropping stats—like nearly identical calorie consumption between nations with wildly different obesity rates—to illustrate how hormones, digestion, and even the microbiome play a much bigger role than just numbers.  We also broke down the three types of hunger—homeostatic, hedonic, and conditioned—and explored how ultra-processed foods hijack our biology. Dr. Fung shared that ditching those foods is his top strategy for conquering hunger, while I revealed how staying busy and using GLP-1s can help curb appetite during fasting or travel.  Dr. Jason Fung is a physician (kidney specialist), researcher and New York Times best-selling author currently practicing in Toronto, Canada. trained in Los Angeles and Toronto and currently practices as a nephrologist (kidney specialist).
