Boundless Life

Full show notes: bengreenfieldlife.com/braindefenders

In this episode, board-certified neurologist Dr. David Perlmutter joins me to talk through his new book, Brain Defenders, and his case that the beta-amyloid drugs for Alzheimer’s (drugs that target a sticky brain protein) haven’t delivered the results many hoped for. You’ll discover how microglia, your brain’s own immune cells, can protect your neurons or damage them, and what may tip them in either direction. You’ll also learn why the metabolism of those cells may mirror the metabolism of your whole body, which could put more of your brain’s future in your hands than you might expect.

David and I also dig into the gut-brain link, from ultra-processed food to fecal transplants, the blood tests he recommends, and how herbicides like glyphosate and paraquat, as well as wildfire smoke, may affect your brain. You’ll learn about duckweed, minocycline, and RNS60, a nanobubble saline being studied in stroke and amyotrophic lateral sclerosis (ALS), what the glucagon-like peptide-1 (GLP-1) trials in Parkinson’s and Alzheimer’s reported, my own accidental retatrutide injection, and the lifestyle trial that reported improvements in early Alzheimer’s after 20 weeks without using any drugs.

You can find his new book, Brain Defenders, here.

In this episode, I’m in the hot seat on Marc Champagne’s Behind the Human podcast, talking identity, legacy, and the story behind my documentary, Boundless: The Man Who Became Human. You’ll hear how tying my worth to achievement pulled me away from my family, the rites of passage I built for my sons, where the “Boundless” name came from, and how Caleb Applegate created a film that Zac Efron executive produced.

We also dig into questions from the AI-powered wisdom keepers in Marc’s new book, You’re Invited, including which practices I’d keep if none of them extended my life and what I finally stopped doing. You’ll learn why exercise beats piling on biohacks, how I stay true to my creative work, my daily, weekly, and annual reflection rituals, what excites me in the longevity space, and what my late father would be proudest of in how I’m raising my sons.

In this episode, repeat guest Michael Feldstein, founder of Jaspr, joins me in my Idaho studio to make the case that synthetic fragrances are the new secondhand smoke. You’ll hear why the air freshener in your Uber may be doing more harm than you think, how fragrance dulls your sense of smell and even your digestion, and what Michael does to keep his air clean on the road when he can’t ship a Jaspr ahead of him.

We also dig into the research tying air quality to cognitive performance, from MLB umpires to chess players to the healthy buildings work of Harvard’s Dr. Joseph Allen, plus what Michael thinks about stacking nasal strips with clean air. You’ll learn how he built Kindling Academy in Austin to be the healthiest school in America, the humidity range that keeps mold and bacteria in check, how to upgrade your car’s cabin filter, and why gyms and dental offices have some of the worst air quality you’ll breathe.

Full show notes: BenGreenfieldLife.com/prologue

In this episode, stem cell scientist Dr. Yaron Fuchs reveals how an accidental lab finding, a compound that turned every hair white, led to Prologue, a peptide serum built to help you keep the natural hair color you still have. You’ll hear why hair goes gray in the first place, how the stem cells that run your pigment “factory” decide whether to live or die, and how his team shrank a large protein into six peptides small enough to reach the follicle.

You’ll also learn the surprising story behind finasteride, from castrated men who never went bald to a rare mutation in the Dominican Republic, and why hair loss medicine has barely advanced in decades. We dig into what his clinical study found, when to start treatments if you want to stay ahead of your first grays, and whether a red light helmet has any real benefits for hair. You’ll also hear how I fit the serum into my morning routine, and how Dr. Fuchs’ lab can grow and test your own hair follicles from a urine sample.

In this episode, Rory Vaden, author of Take the Stairs and cofounder of Brand Builders Group, tackles why people who know exactly what to do still don’t do it, and why the problem is rarely a lack of information. You’ll hear the three types of procrastination, why discipline has less to do with willpower than with vision, and how to multiply your time by spending it on things that create more time tomorrow.

You’ll also learn where biohacking crosses from smart tools into shortcuts, why buffalo run straight into storms, and the return-on-time math behind the AI tool I built to tame my WhatsApp groups, along with why automating chaos only creates chaos faster. We dig into overloaded morning routines, the social pressure of living in an escalator world, and the photo of my 80-year-old self that hangs on my wall, plus how to grab Rory’s Wealthy and Well-Known audiobook for free.

In this episode, orthopedic surgeon Dr. Reza Jazayeri shows you how to prepare for and recover from surgery like an athlete, from the strength you build beforehand to the nutrients, technologies, and anesthesia choices that shape how you heal. You’ll hear why your biology, not the surgeon’s hardware, is now the weak link, why weak quads going into a knee surgery predict how well you function afterward, how he harvests your own cells mid-operation, and why going into surgery starving is outdated. He also explains why the protein guidelines most people follow fall short after an operation, and what NASA’s bed rest studies revealed about the best way to hold on to muscle.

You’ll also learn which amino acids, vitamins, and minerals he uses before and after an operation, where pulsed electromagnetic field therapy (PEMF), hyperbaric oxygen, and red light fit into recovery, which supplements to stop beforehand, and how too much zinc can block copper. We dig into ketones, growth hormone, peptides, and the one-week pause he puts on blood vessel-building peptides after surgery, and I share the stack I would personally use, plus why I banked my own bone marrow stem cells and fat stem cells years ago. Speak with your own physician or surgeon before implementing anything you hear.

In this episode, repeat guest Vince Del Monte, once known as the “skinny guys savior,” opens up about the divorce that broke his eight-figure life wide open, and what it taught him about God, money, and manhood. You’ll hear how a pastor’s kid who swore divorce would never happen to him fell for the three lies driven men believe about their worth: you are what you do, what you have, and what other men think of you. He shares the habits that cost him his marriage, why loving your business more than your wife has become “a societal form of adultery,” and the night his wife said “I’m done” that put him on his knees and into therapy.

You’ll also learn how his prayer life went from performance to a 4 a.m. hour with God, why quiet time beats a perfect WHOOP sleep score, why he threw his trackers in the garbage, and how he stopped letting his body determine his worth. I also share the near-divorce I tell in my documentary, Boundless: The Man Who Became Human. We talk about the “alpha orphan spirit,” shutting down his mastermind, quitting testosterone replacement therapy, alcohol, and caffeine in the same year, and how he’s now leading a relationship in purity. If you’re a woman listening, this is one to send to a man in your life.

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.

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. If you want to go deeper, you can find his new book, Outsmart Everyone, here.

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.
