Fasting: benefits, risks, and practical framework
Attia's evolved view on fasting: the metabolic benefits are real but the muscle loss is a serious trade-off for anyone over 40. His updated framework: time-restricted eating (10-12 hour window) is practical; extended fasts (3+ days) carry risks that may outweigh benefits for most people.
