1) low-calorie food. When we consume less calories than the human body consumes, it is possible to consume the existing fat in the body and achieve the purpose of losing weight. Dieters should try to eat low-calorie foods, such as melon, cabbage, radish and bean sprouts. 2) High fiber food. Fiber can absorb water in the body and sell it together with other wastes, which has a magical weight loss effect. This kind of food can decompose fat or inhibit the accumulation of fat to some extent, such as tea, figs, lemons, coffee and so on. 3) Foods that promote defecation. If the stool is unobstructed, the residence time of food in the intestine will be shortened, and the nutrients absorbed by the human body will be reduced accordingly, which is similar to dieting. Foods rich in cellulose use defecation, such as Ma Tishuang, persimmon, bean sprouts and apples. 4) Diuretic and sweaty foods that consume calories. Although urine can't reduce body fat, it can take away some calories. Sweating and calorie-consuming foods can consume some fat by evaporating calories, and also have the effect of losing weight. Such as watermelon, wax gourd and fruits and vegetables with high water content.
