Effects of Fasting & Time Restricted Eating on Fat Loss & Health | Huberman Lab Essentials

About this video

Huberman explains time-restricted feeding by first insisting on precision about outcomes. Citing a 2018 Gardner study, Huberman says there was no significant difference in weight change between a healthy low-fat and a healthy low-carbohydrate diet over 12 months, and argues weight loss mainly depends on calories burned exceeding calories ingested, while exercise, NEAT, metabolic rate, and hormones affect the calories-out side. For fasting, Huberman recommends a foundational pattern of no eating for the first hour after waking and none within 2 to 3 hours before bed. He suggests a midday window such as noon to 8 p.m. can be socially workable, says an 8 to 10 hour window is easier to sustain than a very short one, and warns against letting the window slide on weekends. He also notes a post-meal walk can help when eating occurs close to a preferred fast.
