Many weight-loss exercisers think that eating meat is long meat, so they dare not eat any meat after strenuous exercise, which leads to excessive loss of body muscles and a decline in health. It is not meat food that causes people to get fat, but rice, which is related to the increase of insulin level after carbohydrate intake. In fact, the intake of low-fat meat will not lead to obesity. Meat food provides essential protein and amino acids for human body, constitutes an important cell structure of human body, and has important physiological significance for human body. It is suggested that people who exercise to lose weight should eat some meat with low fat content.
