In this segment, the speaker argues that humans possess an innate longevity program that can be activated through fasting. Citing animal studies, they note that alternate‑day fasting—eating normally one day, then fasting the next—has been shown to extend lifespan by roughly 30‑80 %. The benefit is not attributed to superfoods or drugs but to the activation of internal bio‑hacking pathways. During fasting, cells initiate autophagy, a self‑eating process that breaks down damaged components and recycles them into new, functional parts, thereby promoting cellular rejuvenation and overall longevity.

So my body knows how to live to be 120 years old, but it's just not doing it. So if you take an animal and you put it on an alternate-day fasting regimen, so eating normally one day, then fasting the next, eating normally one day, fasting the next, rinse and repeat for their entire lifespan, you can see anywhere between like a 30 to 80% lifespan increase just by changing when they're eating. And it's not this superfood or this wonder drug that is creating all that benefit, but somehow fasting is activating this, what I like to call longevity biohacking. program that we all have inside of us but just isn't ordinarily turned on, something that our bodies inherently know how to do and were designed to do. What's happening in your cells during fasting is that they will turn on these cleanup and recycling mechanisms. Autophagy basically means self-eating. The self-eating comes from that, breaking down the old cell junk and turning it into shiny new parts.
