The reason is that, through overnight consumption, the sugar stored by blood night in the human body has almost been lost in the morning. If you exercise on an empty stomach at this time, the human body will immediately use human fat and protein phosphorus, and the efficiency of reducing fat will of course be high. Some authoritative experts believe that the order of energy consumption during fitness exercise is sugar and carbohydrate, protein and body fat, so when sugar and carbohydrate and protein are consumed, fat will be burned. Although human body fat will eventually be consumed through long-term activities, during the sleep quality period, the basic metabolism of the body will proceed normally.
Therefore, when you wake up in the morning, the offspring will be in a state of lack of sugar and carbohydrates. In this case, running on an empty stomach should burn fat quickly, and the actual effect of losing weight will be more obvious.

If you run on an empty stomach, you are likely to have hypoglycemia symptoms, such as panic, sweating, trembling hands and feet, and even become a fatal factor. In order to lose weight quickly, some people always insist on running on an empty stomach, and don't supplement vitamins immediately before and after running, which can easily damage the life activities and functions of key organs of the human body, such as the brain, central nervous system and cardiovascular system, which is very unfavorable to health.
Wake up in the morning without eating, and 2 hours after meals can also be called fasting. Therefore, it is very important to choose a suitable running time on an empty stomach, which can also speed up weight loss. The suitable running time points are 7: 00, 9: 00, 15 and 2 1: 00 respectively. In short, the best time for exercise is not necessarily, but the most suitable time is better.
