Before exercise, properly replenish water and sugary foods, such as a small piece of bread, 50g of rice, or dark chocolate (don't eat chocolate containing milk). Eating carbohydrates before training is to reduce fat during exercise. What sports are going viral on the Internet? It's time to lose fat, it's true, but there is a premise that most people don't know, that is, when the human body has sufficient glycogen reserves, the energy is originally supplied by the stored sugar in the first 45 to 55 minutes of human exercise, and then the fat will be used to participate in energy supply. (As the name implies, it is the participation function. As for those claims of reducing fat, they are all added by dieters themselves. )

Many people start exercising on an empty stomach or at least 3 hours after meals. It takes 2.5 to 3 hours for carbohydrates to be digested and absorbed in the body. Therefore, most people have a poor effect of reducing fat, just because they always start exercising on the premise that the human body is not full of glycogen. But also misled by the false statements of the media. What's more, it is said that fat starts to burn after 30 minutes of exercise. If the sugar reserve is insufficient, the metabolism during exercise is basically water and muscle, with only a little fat, and with little exercise time, fat basically does not participate in metabolism. Losing weight does not mean losing fat. Most of the weight loss is water and lean body weight. If lean body mass is reduced, metabolic rate will be greatly reduced with weight loss, and metabolism will be slower. Once you stop training and replenish water properly, your weight will still recover, which is the main reason why many friends rebound after losing weight.
