The secretion of growth hormone will stimulate appetite and make people feel hungry. At this time, the level of leptin in the body will be reduced. Leptin is originally used to suppress hunger. Once its level is lowered, people will feel hungry. However, the two hormones work together in the middle of the night Use, it will make people feel more hungry, which is why many people feel more hungry in the middle of the night. Because these two hormones work together, so it is too difficult to satisfy the appetite without eating. Therefore, people who stay up late are unable to resist the fierce appetite and eat obediently. As a result, it is impossible to lose weight and only gain weight.
