"Materia Medica" mentioned a function of tea: "Long-term consumption makes people thin and removes human fat." It shows that drinking tea in ancient times can make people thin.

From the perspective of modern science, some compounds in tea can effectively promote intestinal peristalsis and help digest food.

Tea can keep people in good shape, probably because it contains caffeine, tea polyphenols and other alkaloids, as well as a variety of mineral components.

Caffeine can enhance metabolism and make the body consume a certain amount of fat, while tea polyphenols assist the decomposition and digestion of fat. Minerals can stimulate the activity of lipolytic enzymes in the pancreas and reduce the absorption of fat and sugar foods.

From these aspects, it has really played a role in reducing fat and weight. But this kind of weight loss is mainly about blood lipids and digestive tract oils, and has nothing to do with subcutaneous fat.
