Most people track glucose or ketones, but almost no one is measuring the hidden signal that could be silently wrecking your metabolism, brain function, and longevity: uric acid. This episode reveals why this overlooked biomarker drives obesity, diabetes, cardiovascular disease, Alzheimer’s, and even accelerated aging—and how you can hack it to unlock resilience, human performance, and smarter not harder health upgrades. Watch the podcast on YouTube for the full video experience: https://www.youtube.com/@DaveAspreyBPR We revisit host Dave Asprey sitting down with Dr. David Perlmutter, one of the world’s leading functional medicine neurologists and the #1 New York Times bestselling author of Grain Brain and Drop Acid. Dr. Perlmutter has spent decades connecting gut health, brain optimization, and neuroplasticity with lifestyle interventions that truly change the trajectory of disease. In this conversation, he explains how uric acid acts as a metabolic switch that determines whether you burn fat or store it, whether your mitochondria power you up or slow you down, and whether your brain stays sharp or declines with age. They break down how fructose, purines, alcohol, and even dehydration spike uric acid, why Japan is decades ahead in using this as a health marker, and how supplements like quercetin and luteolin rival pharmaceuticals in keeping it under control. You’ll also learn how ketosis, fasting, cold therapy, carnivore and plant-based approaches, and sleep optimization all interact with uric acid to shape your healthspan. This is biohacking at its most actionable—because once you measure this signal, you can control it, and once you control it, you radically upgrade your metabolism, your brain, and your longevity. This is essential listening for anyone serious about hacking their biology, building neuroplasticity, powering up mitochondria, exploring nootropics, and discovering smarter not harder ways to live longer and perform better. You’ll Learn: • Why uric acid may be the most important overlooked biomarker for longevity • How it connects obesity, diabetes, cardiovascular disease, and Alzheimer’s • The evolutionary reason your body uses uric acid as a survival signal • How fructose and hidden sugars sabotage metabolism and brain optimization • The role of quercetin, luteolin, and targeted supplements in lowering uric acid • Why measuring at home with a simple device can change your health trajectory • How functional medicine uses uric acid as a predictive tool for chronic disease Dave Asprey is a four-time New York Times bestselling author, founder of Bulletproof Coffee, and the father of biohacking. With over 1,000 interviews and 1 million monthly listeners, The Human Upgrade is the top podcast for people who want to take control of their biology, extend their longevity, and optimize every system in the body and mind. Each episode features cutting-edge insights in health, performance, neuroscience, supplements, nutrition, hacking, emotional intelligence, and conscious living. Episodes are released every Tuesday, Thursday, and Friday (audio-only) where Dave asks the questions no one else dares, and brings you real tools to become more resilient, aware, and high performing. Keywords: uric acid longevity, uric acid metabolism, fructose uric acid pathway, xanthine oxidase inhibition, quercetin uric acid, luteolin supplements, AMP kinase uric acid, AMP deaminase metabolism, uric acid and mitochondria, uric acid and neuroplasticity, uric acid Alzheimer’s risk, uric acid dementia prevention, uric acid and nitric oxide, fructose metabolism hibernation biology, evolutionary mismatch uricase mutation, fructokinase inhibition, uric acid and insulin resistance, gout biohacking, uric acid and obesity, uric acid functional medicine Resources:  • David’s Website: https://drperlmutter.com/ • Danger Coffee: https://dangercoffee.com/DAVE15 • Dave Asprey’s BEYOND Conference: https://beyondconference.com • Dave Asprey’s New Book – Heavily Meditated: https://daveasprey.com/heavily-meditated • Upgrade Collective: https://www.ourupgradecollective.com • Upgrade Labs: https://upgradelabs.com • 40 Years of Zen: https://40yearsofzen.com Timestamps: 0:00 — Trailer 0:35 — Introduction 2:26 — Why Uric Acid Matters 5:55 — Measuring Uric Acid 8:17 — Disease Risk 9:38 — Metabolism Disruption 15:59 — What Raises Uric Acid 26:20 — Global Research 29:50 — Gut & Inflammation 32:55 — Seasonal Eating 47:36 — Brain Health 56:38 — Supplements & Testing 61:45 — The LUV Diet 71:41 — Closing Insights See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Your dopamine system is being hijacked every day, and the way to reclaim it might surprise you. This episode reveals how pain, pleasure, and addiction are wired in your brain, and how to use that knowledge for real brain optimization, resilience, and longevity. You’ll discover why your dopamine levels control motivation, focus, mood, and even cravings—and the science-backed strategies that reset your neuroplasticity, metabolism, and reward system. Watch this episode on YouTube for the full video experience: https://www.youtube.com/@DaveAspreyBPR Host Dave Asprey sits down with Dr. Anna Lembke, Stanford psychiatrist and bestselling author of Dopamine Nation. She is one of the world’s leading experts on addiction, compulsive behavior, and the neuroscience of reward pathways. With decades of clinical work and groundbreaking research, she explains why dopamine has become the modern lens for understanding desire, distraction, and dysfunction—and how we can hack it to upgrade human performance. They break down how dopamine drives addiction, why pain can reset your reward system, and how simple practices like fasting, cold therapy, and supplements affect your brain chemistry. You’ll learn how nicotine, GLP-1 drugs, and even nootropics alter dopamine sensitivity, and why overstimulation from social media, pornography, and ultra-processed food is creating an epidemic of anhedonia. The conversation also covers how functional medicine and biohacking can protect your mitochondria, restore your natural dopamine balance, and make your brain more resilient. You’ll Learn: • Why dopamine itself is not addictive—and what really drives addiction • How pain, hormesis, and “dopamine fasting” can reset your reward system • Why social media and digital overstimulation create chronic dopamine deficit states • The role of GLP-1 drugs, nicotine, psychedelics, and other substances in rewiring dopamine • How functional medicine and supplements help restore dopamine balance • The connection between dopamine, mitochondria, fasting, cold therapy, and longevity • Why radical honesty and self-binding are powerful anti-addiction hacks This is essential listening for anyone serious about hacking dopamine for better focus, sleep optimization, metabolism, and long-term brain health. Whether you’re curious about the link between dopamine and neuroplasticity, looking to upgrade human performance with smarter not harder tools, or just want to know how to stop dopamine hijacks from ruling your life, this episode gives you the science and strategies you need. Dave Asprey is a four-time New York Times bestselling author, founder of Bulletproof Coffee, and the father of biohacking.
