Bulletproof Radio

You are not eating because you are hungry. You are eating because you have been trained to, and the food industry designed it that way. This episode dismantles everything you thought you knew about hunger, weight loss, and metabolism, and gives you a science-backed framework to finally stop fighting your own biology.  -Watch this episode on YouTube: https://www.youtube.com/@DaveAspreyBPR  Host Dave Asprey sits down with Dr. Jason Fung, a New York Times bestselling author, practicing nephrologist, and one of the most trusted voices in functional medicine and metabolic health.

I lost 100 pounds, dropped to 4.8% body fat, and my lab tests say I'm biologically in my 30s... at 50 years old. Here's everything I got wrong about weight loss for years, and what actually worked.After 18 months of low-calorie dieting and 700+ hours in the gym with zero fat loss, I discovered the truth about saturated fat, intermittent fasting, and why putting butter in my coffee every morning changed everything. This is the foundation of the Bulletproof Diet... and it's helped people around the world lose over a million pounds.In this video I break down 9 weight loss myths that are keeping you fat and tired:Why saturated fat is NOT bad for you (and what the real science says)The truth about low-fat diets and why they wreck your hormonesWhy counting calories is the wrong tool for fat lossHow intermittent fasting and butter coffee keep you in fat-burning mode all dayThe anti-nutrients hiding in "healthy" vegetables, whole grains, and fruitWhy 20 minutes of exercise per week beats 6 days in the gymWhether you'

This week's stories: ***Virologist Self-Injects Oncolytic Virus Therapy, Achieves 4-Year Remission in Triple-Negative Breast Cancer*** A researcher facing terminal triple-negative breast cancer (28% 5-year survival rate) engineered her own measles and vesicular stomatitis viruses and self-administered seven doses directly into her tumor outside formal clinical infrastructure. Four years cancer-free. Dave breaks down the mechanistic basis for oncolytic virotherapy—why cancer cells can't mount antiviral defenses that healthy tissue can—and the regulatory tension between patient autonomy and FDA gatekeeping on experimental immunotherapies. This is either a triumph of DIY biohacking or a cautionary tale about biosafety; either way, oncolytic virotherapy is accelerating toward mainstream clinical use and forcing a reckoning about access to cutting-edge cancer immunology. Sources: -https://www.dana-farber.org/newsroom/news-releases/2026/virus-bas

My favorite creatine (discount code DAVETUBE): https://www.qualialife.com/ASPREYRECOMMENDSCreatine isn’t just for bodybuilders. It’s one of the most overlooked, science-backed nootropics for brain optimization, neuroplasticity, mitochondrial energy, and total human performance.

I spent over $2 million hacking my own biology to reverse my age, but one of the most powerful discoveries didn’t come from a pharmaceutical lab. It came from NASA.Try Danger Coffee: https://dangercoffee.com/dave (Discount Code DAVETUBE)Try Energy Bits: https://energybits.com/discount/daveAstronauts face the harshest environment known to science: space radiation. To keep them alive, NASA had to identify a nutrient dense enough to protect DNA and mitochondria from extreme oxidative stress. They found it in algae (spirulina and chlorella)—a superfood older than civilization that acts as "biological armor" for your cells.In this episode, I break down why "aging" is actually just a buildup of oxidative stress (cellular rust) and how most antioxidants fail to fix it because they never reach the mitochondria. I reveal the exact science behind why algae works, the specific molecules (phycocyanin and chlorophyll) that protect your cellular walls, and the protocol I use to keep my liver young and my energy stable.We a

Try TrueDark (with my discount): https://truedark.com/discount/DAVETUBEI have spent 20 years and over $2 million testing my biology, and the biggest lesson I've learned is that sleep is a neurological system, not just a chemical one. Most people fail to get deep rest because they are stuck in Beta brainwaves—a state of hypervigilance fueled by stress and blue light. You can take all the melatonin in the world, but if your brain is electrically "awake," you will stay "tired but wired."The "switch" I use to fix this is an amino acid called L-theanine. It crosses the blood-brain barrier to increase Alpha waves, which quiet the prefrontal cortex and stop overthinking. By boosting GABA and lowering glutamate, it prepares the brain for rest without the groggy "hangover" of traditional sedatives.To make this work, I follow a strict protocol: taking 400mg–1000mg about 45 minutes before bed on an empty stomach. I also protect my "Alpha state" by blocking blue and green "junk light" with TrueDark glasses, which prevent
