It is easy for girls to gain weight because of hormone secretion during adolescence, so if they want to lose weight, they should aim at two problems. One is to reduce stimulation and make it secrete more hormones, and not to eat "fat" foods, such as fried foods and high-fat and high-protein foods. Then, instead of watching videos about yellow, they concentrate on reading. The second is to participate in fitness and improve the muscle level of the body. Muscle is the engine of the body, which can effectively convert chemical energy into internal energy and kinetic energy, and what you eat can be consumed. Walking is a good exercise, which can effectively exercise thigh muscles without thickening calves. It is also the most effective exercise that consumes energy.
