Second, eat more food containing dietary fiber, which can slow down the movement of food from stomach to intestines, and make people feel full easily. In addition, dietary fiber has a characteristic, which is easy to expand when encountering water. When the expanded dietary fiber compresses the gastric mucosa, it will transmit the feeling speed of fullness to the excitation and satiety center of human brain, so as to send out the command that the stomach has been filled, so as to reduce the feeding requirements of human beings. Less food, less calories. People don’t get fat.
