Essentials: Effects of Fasting & Time Restricted Eating on Fat Loss & Health

Huberman Lab

In this Huberman Lab Essentials episode, I explore intermittent fasting and time-restricted eating, highlighting the positive benefits for weight loss, metabolism, organ health, circadian rhythms and cellular repair.

I explain a practical framework for designing a time-restricted eating window that aligns with your lifestyle, exercise schedule and social schedule. I also cover what breaks a fast, how to support fasting with tools like salt intake and post-meal walks, and the use of fasting-related supplements, including berberine and metformin.
