Black Coffee
High-quality black coffee, one of the most widely recommended beverages during intermittent fasting. Contains caffeine and chlorogenic acid, which may increase metabolic rate and fat oxidation. Dr. Jason Fung considers black coffee an excellent fasting companion — it suppresses appetite, does not stimulate insulin, and may enhance the metabolic benefits of fasting.
