Summary
In this episode, Dr. David Jockers sits down with fasting expert Ben Azadi, host of the Metabolic Freedom Podcast and author of the book Metabolic Freedom, for a detailed, hour-by-hour walk through exactly what happens inside your body during a 72-hour water fast. You will learn what's really going on at each stage of a fast, from the first 12 hours of digestive rest all the way through ketone production, autophagy, mitochondrial biogenesis, and a dramatic spike in growth hormone, plus why your body targets visceral fat and old, damaged proteins before anything else. Dr. Jockers and Ben also cover how to prepare your body before a long fast, what to eat (and avoid) once you break it, which liquids and supplements actually support a fast, and the specific dopamine and immune system resets that happen at the 48 and 72 hour marks.
