Is aging an inevitable decline, or just a "repair backlog" your body hasn't cleared yet?. In this episode, Dave breaks down the 2016 Nobel Prize-winning science of autophagy—the body's internal recycling system discovered by Dr. Yoshinori Ohsumi.Most people are stuck in a state of "biological debt," where cellular junk piles up like trash in a factory, leading to brain fog, fatigue, and chronic inflammation. Standard 16-hour fasts aren't enough to reach the deep-cleaning phase. You will learn the exact 3-day protocol to trigger a "Deep Reset," where ketones peak, inflammation falls, and stem cells wake up to rebuild your immune system from scratch.Join my FREE Fasting Challenge: https://daveasprey.com/fast-this-way-challenge/Timestamps:00:00 - The Anti-Aging Switch01:30 - Chronological vs. Biological Age02:32 - How Aging Works at the Cellular Level04:58 - 43 Ways to Upgrade Your Mitochondria07:37 - What Is Autophagy09:17 - The Stages of Fasting10:46 - What Happens During a 3-Day Fast13:04 - How to Fast Correctly14:42 - Breaking the Fast15:58 - The Power of SubtractionThank you to our sponsors!-KILLSwitch | If you’re ready for the best sleep of your life, order now at https://www.switchsupplements.com/ and use code DAVE for 20% off-Join My Low-Oxalate 30-Day Challenge: https://daveasprey.com/2026-low-ox-reset/Connect with Dave Asprey!Website: https://daveasprey.comTikTok: https://www.tiktok.com/@daveaspreyofficialInstagram: https://www.instagram.com/dave.asprey/Facebook: https://www.facebook.com/Daveaspreyofficial/X: https://x.com/daveaspreyYouTube: https://www.youtube.com/c/daveaspreybprThe Human Upgrade Podcast: https://www.instagram.com/TheHumanUpgradePodcast/ https://m.facebook.com/Thehumanupgrade/Danger Coffee: https://dangercoffee.com/DAVE15Dave Asprey’s BEYOND Conference: https://beyondconference.com/Dave Asprey’s New Book - Heavily Meditated: https://daveasprey.com/heavily-meditated/Dave's favorite supplements: https://www.shopsuppgradelabs.com/discount/DAVE15Upgrade Labs: https://upgradelabs.com40 Years of Zen: https://40yearsofzen.comSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
