2. It will consume a lot of physical strength in the process of exercise, and high-intensity exercise uses a lot of nutrients in the body. Within one hour after exercise, the body is at the best time to absorb nutrients. At this time, it is best to supplement nutrition and absorb. Only by supplementing all kinds of nutrients needed by the body in time will it not cause harm to the body because of exercise.
3. 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.
4. In high-intensity exercise, you should also supplement some drinks containing oligosaccharides to avoid excessive deficit during exercise. After exercise, the metabolic rate of the body increases, 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 small steamed bun or three or four pieces of toast with a boiled egg, not too heavy, can also drink a small amount of freshly squeezed juice or sports drinks. The intake of carbohydrate food and protein is helpful to the rapid recovery of muscles and reserve energy for the next exercise. Eating inappropriate food after exercise, or not eating at all after exercise, will damage the health of exercisers. Exercise itself is a kind of physical expenditure, so you should "refuel" afterwards. Scientific research shows that carbohydrates are the main energy consumed by human activities, and carbohydrates are usually stored in glycogen of muscle cells. During exercise, glycogen stored in the human body will be consumed, so it is necessary to supplement carbohydrates. If you don't replenish it in time after exercise, it will usually lead to muscle loss and weakness, which will easily make people feel tired in the next exercise. In the long run, it will be harmful to people's health.
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. For people who lose weight, the ideal carbohydrate foods are beans and whole grains.
6. In addition, the diet before exercise is also very important, and fasting exercise is prone to hypoglycemia. Before exercising, you should give priority to foods with high sugar (carbohydrate) content in protein, which can help you burn more fat during exercise.
