Drinking tea has the function of losing weight. There is an ancient saying that drinking tea makes you fat: that is, eliminating fat, similar to modern "losing weight". Materia Medica often has the sentences of "strengthening intelligence", "transforming bones" and "prolonging life", which actually means relieving boredom and eliminating fat. There are also many documents about this effect of tea, such as Illustration of Materia Medica, Materia Medica of Food, and Theory of Rice Twelve. Herbal Supplement says that tea "makes people thin after eating for a long time". According to modern scientific research, drinking tea can reduce fat, because tea contains polyphenols such as catechin, caffeine and vitamins, especially catechin can significantly reduce the content of visceral fat. Therefore, drinking tea for a long time can promote human metabolism and fat oxidation, remove excess fat in human body, and help balance body muscles. Keep the weight balance to achieve the purpose of "losing weight", instead of directly reducing "weight" by drinking tea, we should correctly understand and understand the relationship between drinking tea and losing weight. That kind of tea has a good weight loss effect. The content of catechin in unfermented green tea is the highest, followed by oolong tea, black tea and Pu 'er tea. But it should be suitable for everyone. It is worth mentioning that drinking tea for a long time may help reduce the proportion of body fat, but it may not be suitable for everyone. For example, patients with iron deficiency anemia should not drink tea when eating, so as not to hinder the absorption of iron from food. If you want to drink tea, choose between two meals; In addition, insomniacs or neurotic people should also choose the time for drinking tea, and it is best not to drink it after dark to avoid falling asleep at night. In fact, in addition to genetic and endocrine factors, many obese people are caused by excessive calorie absorption and insufficient exercise. If obese people drink tea for a long time, it will help them lose weight. Reasonable and scientific diet, adhere to moderate exercise. Only by drinking tea for a long time can we achieve the effect of "losing weight". (Editor of Tea Ceremony Nakamura)
