#353 - AMA #72: Fasting: benefits for body composition and disease prevention, potential risks, and Peter’s updated practical framework

This is a sneak peek of an Ask Me Anything (AMA) episode of The Drive Podcast with Peter Attia, focusing on the topic of fasting, which was initially covered in January 2020. The episode will explore various types of fasting, reasons for fasting, potential benefits (body composition, metabolic health, lifespan, cardiovascular disease, cancer, Alzheimer's, autoimmune symptoms), and potential negative aspects. Peter Attia emphasizes the importance of being able to change one's opinion in light of new information and defines the terms DR (dietary restriction), TR (time restriction), and CR (caloric restriction) in the context of nutrition and fasting. He also lists the most common types of fasting, such as intermittent fasting, alternate day fasting, periodic fasting, time-restricted eating, and long-term fasting. The episode includes a discussion of Peter Attia's personal experiences with different fasting protocols and a historical anecdote about Angus Barbieri's year-long fast.
