Tomato slimming advocates eating a tomato before meals, which contains dietary fiber that is not digested and absorbed by the human body. While reducing the intake of rice and high-calorie dishes, prevent 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 peristalsis, thus helping the dietary fiber in tomatoes absorb excess fat in the intestines and excrete it with waste. For people with cold constitution or weak stomach, you can choose to heat tomatoes or tomato juice.
