Full Show Notes: https://bengreenfieldlife.com/lnneel/ Aching tightness, head-splitting migraines, breathing issues, and poor sleep quality — these are all signs of trapped tension in your body. The good news is that exercising one specific (and often forgotten) body part can help restore your well-being… I'm talking about your tongue… I first discovered how to unlock the power of whole-body tension relief when Dr. Neel Bulchandani visited my house and did some very unique body therapy on me (including putting his fingers into my mouth and my nasal cavity to 'adjust' those sections)! I later released an Instagram post about his groundbreaking Tongue Press program — a video series and guide designed to optimize tongue mobility. Dr. Bulchandani is a holistic chiropractor and bodywork educator who has poured over 15 years of chiropractic expertise and five years of training fellow bodyworkers into creating not just To

Full Show Notes: https://bengreenfieldlife.com/494 In this episode, I dig into the fascinating story of the world’s oldest woman—a vibrant supercentenarian from Spain who made it to 117 years old. I break down what researchers discovered about her genes, lifestyle, and daily habits (you might be surprised by some of the things she ate and didn’t do!). I also get nerdy about the newest longevity drugs and supplements—like curcumin, spermidine, taurine, and a few others you might not expect—and explain which ones actually work, according to the science in mammals. Plus, I share some updates from my own life, like the weirdly exciting health setting I just found on my new iPhone, and spill the beans on why I microdose alcohol (and sometimes other things) instead of going on a bender. If you’re curious about muscle gain (do you really need to be in a calorie surplus?), soft-shell vs hardshell hyperbaric chambers, or how certain supplements might actually help you live longer, y

Full Show Notes: https://bengreenfieldlife.com/lnamie/ Low libido... brain fog... and decreased muscle mass — many women face these issues without realizing they could be linked to hormone imbalances, particularly low testosterone levels.

In this special live-recorded episode, actor Luke Cook—known for Chilling Adventures of Sabrina and Guardians of the Galaxy Vol. 2—joins me for a raw, unfiltered conversation about what it really means to live well. Recorded during A Boundless Evening at HUME Los Angeles, this fireside chat brings together curiosity, science, and honest reflections on health, performance, and purpose. We start with the rhythms of daily life—how I approach mornings, training, and eating while traveling—and why balance beats perfection. You’ll hear how my cyclical keto approach helps me stay sharp and grounded while still enjoying the moments that matter. From movement habits and fasted training to the little environmental tweaks that keep me active throughout the day, we explore how health can be both sustainable and joyful.

By weaving together mainstream medicine and holistic practices, Dr. Warsh highlights where the science is strong, where questions remain, and why open conversation is the path toward clarity, confidence, and compassion—and if you’re interested in cutting through fear and hype to underst

In this episode we dive into a hotly debated topic: should you eat meat or not? Ben is joined by two powerhouse guests with decades of experience in nutrition and health—Dr. Shawn Baker, best-selling author of The Carnivore Diet and leading carnivore advocate, and Joel Greene, creator of The Immunity Code and champion of dietary diversity. In this spirited debate, Dr. Baker highlights the benefits of a strict carnivore approach—meat, eggs, some dairy, and minimal plant foods—not only for himself but also for patients managing chronic health issues. He explains why animal-based nutrition can be so effective, breaks down the science of ketosis and gut health, and responds to concerns about long-term effects of fiber-free diets. Meanwhile, Joel Greene makes the case for dietary variety, drawing from evolutionary biology, clinical research, and personal experience. He explores the synergies of combining animal and plant foods, the role of fiber in gut and immune health, and the ancestral rhythms

In this episode, Emily Kaplan—co-founder of the Broken Science Initiative (BSI)—pulls back the curtain on systemic flaws undermining modern research.
