This is because the process of exercise is the process of physical exertion, and high-intensity exercise consumes a lot of nutrition. After the exercise, the body is in the best time to absorb nutrition, and at this time the body is in the best state to supplement nutrition. Only by supplementing the nutrients needed by the body in time will it not cause harm to the body.
After exercise, the body needs to supplement a lot of calories and other trace elements, and the metabolic rate is high. Eat in time after exercise, and the supplementary nutrition will be converted into calories needed by the body, reducing the chance of being converted into fat.
After strenuous exercise, the body's metabolic rate rises, and eating at this time helps to excrete harmful substances in the body. After exercise, protein and carbohydrate should be the main components, and the ratio is 1:2. For example, a steamed bun or three or four pieces of toast with a boiled egg, not too heavy, can be drunk with a small amount of freshly squeezed juice.
On the contrary, if you eat after 1-2 hours, you will not only feel hungry, but also miss the best opportunity to absorb nutrients. Even if you take enough nutrients, your body can't absorb them well.
And after 1-2 hours of exercise, the body's metabolism returns to normal, and the calories needed by the body are supplemented. At this time, most of the nutrients absorbed are converted into fat and stay in the body, which will never play a role in losing weight.
In addition, the diet before exercise is also very important, and fasting exercise is prone to hypoglycemia. Before exercising, you should give priority to high-protein foods, which can help you burn more fat during exercise.
