METABOLIC INTELLIGENCE
Weight loss is a symptom. The real lever is insulin — the hormone that decides whether you store fat or burn it. FatTonic gives you the science, the tools, and a daily system to make your metabolism work for you.

FatTonic is a science-based platform for optimizing your body's fat-burning system by lowering insulin. It combines a free Metabolic Score, a Food Index that rates foods on how much they help or hurt fat-burning, and a science library.
Spend more of the day with low insulin: cut liquid sugar, lead meals with protein and fiber, walk after eating, sleep well, build muscle, and choose low-glycemic-load foods. FatTonic scores every food so you can do this without guessing.
No. The FatTonic Score is an educational rating built from glycemic load, sugar, fiber, protein and processing level. It is not a clinical measure or medical advice.
