Why Do We Still Use 150-Year-Old Technology To Measure the #1 Killer of Humans Worldwide? The New Approach To Blood Pressure Measurement With Tom Moss.

Full show notes: BenGreenfieldLife.com/507 In this episode, you’ll discover how much protein to eat in a calorie deficit to hold on to muscle, which bodybuilding myths you can drop, and what can help tighten loose skin after GLP-1 weight loss. I walk you through a new meta-analysis of 29 studies on dieting lifters, why I set my own target higher at 1 to 1.5 grams per pound, and whether switching up exercises builds bigger arms. You’ll also learn how close to failure you really need to train, why fasted cardio may not burn more fat, and why skin sags when weight comes off fast, including the 7% of facial volume lost per 10 kilograms. I also dig into whether lifting makes women bulky, whether cardio kills your gains, whether you need to eat every three hours, and whether creatine is a steroid (it’s not). You’ll hear why I lift heavier loads on Nautilus machines, the essential amino acids my sons and I take twice daily, why I train fasted on ketones and amino acids, and my morning coffee fat-loss routine. We finish with strategies for tightening loose skin, including collagen, an at-home iRESTORE red light panel (use code BENPRO for $25 off), clinical treatments, and surgery, plus how to keep loose skin from deciding your self-worth.

Full show notes: BenGreenfieldLife.com/spysecrets In this episode, I’m re-airing my conversation with former covert CIA officer Andrew Bustamante, founder of EverydaySpy. My friend Adam Wenguer introduced us by saying Andrew was great at marriage, homeschooling, and biohacking, and that he used to be a spy. You’ll hear what a polygraph really measures, how the CIA rebuilds officers after an operation, and the recovery tools he leans on, including L-theanine, CBD oil (use code BEN15 for 15% off), and watered-down electrolyte drinks (get a free sample pack with any drink mix order). Andrew walks through his CIA morning routine, from a big glass of water and a Transcendental Meditation® mantra to berries instead of coffee, plus why the agency wants your heart rate up early and why he shuts off screens 90 minutes before bed. You’ll also hear about the two popular sleep aids I think cut into your REM sleep, the “perspective” exercise that changed his marriage, the “false dilemma” that heads off most bedtime fights with kids, and how I talk to my own sons about porn. We also cover why he journals in fragments and turns them into spreadsheet dashboards, and why switching up your workouts beats the same treadmill run every day.

Full show notes: BenGreenfieldLife.com/healthyheart In this episode, I’m re-airing my conversation with biochemist and engineer Patrick Theut about how he cleared the plaque from his own heart. Patrick was 48, winning 5Ks and playing ice hockey when he passed every test in a Mayo Clinic physical, then asked for one more scan they said he didn’t need. It came back with his left main artery lit up, and a cardiologist gave him four years to live. I went through something very similar myself, which is why this one stuck with me. You’ll hear how gut bacteria help make vitamin K, how a common antibiotic can wipe them out, the health crash that sent his calcium score soaring, and the vanadium protocol he used to rebuild his pancreas, plus my company’s bitter melon blood sugar formula, Kion Lean. We get into the statin experiment he ran on himself, why vitamin K may help athletes train harder, what to know if you take blood thinners like warfarin, and his bare-minimum protocol, from magnesium (use code BEN15 for 15% off) and vitamin D to vitamin C. We close with his take on statins, the heart marker he thinks matters next, his once-a-day eating, and the fermented Paleovalley beef sticks (use code PVFRIEND15 for 15% off) I’ve been working my way through. If you want to try Patrick’s vitamin K blend for yourself, you can find Koncentrated K here.

Full show notes: BenGreenfieldLife.com/thymuspodcast In this episode, I sit down with internal medicine physician Dr. Abud Bakri to talk about the thymus, the small gland on top of your heart that trains your immune system and starts shrinking as soon as you hit puberty. You’ll hear what speeds that shrinkage up, from birth control and testosterone therapy to chronic infections, stress and a leaky gut, why Korean eunuchs lived longer, and which blood markers, like the ratio of helper to killer T cells (CD4-to-CD8 ratio), give you a window into how your thymus is doing. We get into thymulin and zinc, thymosin alpha-1, the Russian thymus extract Thymalin, and whether eating sweetbreads does anything at all. You’ll also hear my bedtime stack of epitalon and Pinealon, why Abud shines red light on his sternum, the overlooked link between the thymus and testosterone, why he takes 40 times my dose of body protection compound 157 (BPC-157) for injuries, and the red flags to watch for before you inject any peptide. We also cover natural killer cell treatments, the libido peptide being tested for weight loss, and why Abud thinks lactoferrin and colostrum are about to catch on.

Full show notes: BenGreenfieldLife.com/lowcarbhighcarb In this episode, I'm re-airing the first debate ever held on the Boundless Life podcast, with repeat guest Jay Feldman and Duke obesity medicine physician Dr. Eric Westman going head to head on whether your cells run better on carbohydrates or fat. The carbs-are-good, carbs-are-bad argument has only gotten louder, and this is still the best version of it I've heard. You'll hear Jay's case that burning fat creates more oxidative stress and drives up stress hormones like glucagon and cortisol over time, and Eric's case from decades of reversing type 2 diabetes in his clinic. We get into the KetoSAge study that pulled keto-adapted women out of ketosis, the KETO Trial on keto dieters with very high LDL cholesterol, what a failing heart actually burns, and why keto adaptation can take months. We close on the membrane pacemaker theory of aging, survival versus thriving, how I scale my own carbs to training and travel, and the three carb levels Eric lays out in End Your Carb Confusion. Whether you eat keto, high-carb, or somewhere in between, this debate will sharpen how you think about fuel.
