Green Tea vs. Black Coffee—which one actually wins the fat-loss battle? Part 1 of our science-backed guide breaks down the exact biological mechanisms of both. Discover how Green Tea uses EGCG catechins to safely boost fat oxidation by up to 17% over 24 hours without fading, while Black Coffee directly stimulates the nervous system for a powerful, acute metabolic spike. We analyze everything from caffeine levels per cup to real-world insulin sensitivity data to show you how these compounds affect fat storage.
