Won’t gain weight.

"Tomato Slimming" advocates eating a tomato before meals. The dietary fiber contained in it is not digested and absorbed. It reduces the intake of rice and high-calorie dishes and prevents the body from absorbing more fat in food. The unique sour taste of tomatoes can also stimulate the secretion of gastric juice and promote gastrointestinal motility to help burn fat. It also helps the dietary fiber in tomatoes absorb excess fat in the intestines and excrete it together with fat and waste. Each 100 grams of tomatoes contains 16 calories. Even if you eat a medium-sized tomato (250g), it only has 40 calories, which is equivalent to one-fifth of a bowl of rice. An apple of the same weight contains 107 calories, while a tomato has less than half the calories of an apple. Generally, the basic method is to eat a medium-sized tomato before a meal. You can also use 180-250cc of salt-free tomato juice instead.
