Editorial department/comprehensive leptin is a hormone in human body, which is related to appetite and slimming. Let's take a look at the following introduction. Function: Suppress appetite and control satiety. After eating, leptin is secreted, which makes people stop eating. At the same time, lean voxel also has the function of burning calories, which is very important for slimming. Causes of imbalance: lack of sleep, excessive abdominal fat, and gluttony of leptin is protein secreted by fat cells. Its receptors are distributed all over the body, but they are particularly active in the brain, which is responsible for increasing calorie consumption and suppressing appetite. If leptin works well, it will send a satisfactory signal to the nerves after eating, telling the brain that "I'm full" and making us stop eating. However, people who don't get enough sleep will lose 20% of leptin, making it difficult to feel full, and as a result, they will unconsciously eat more food and calories than usual. In addition, people with obese abdomen will have high leptin concentration, which will produce "impedance" and reduce their sensitivity to leptin. Therefore, when they eat, they will not feel the satiety signal sent by leptin, and they will easily overeat and form a vicious circle. Countermeasures: chew every bite of food for 20~30 times and eat at least half an hour at a meal.
