When a person sleeps, the body releases a chemical called "leptin", which can remind people that they are full, thus controlling the amount of fat. Lack of sleep may affect the secretion of hormones that help burn calories during the day, and lack of sleep will affect the secretion of leptin, so it is not difficult to see that sleeping to lose weight is also an effective way to lose weight.

If you don't get enough sleep, your fat storage will increase. When you fall into a deep sleep, your brain will release a lot of growth hormones, which will instruct your body to break down fat and release energy. But if you absorb extra calories and lack deep sleep, then you lack enough growth hormone to break down these fats. Then, your body will take this shortcut and pile up excess fat on your hips, thighs and abdomen.

However, it is not that the more you sleep, the better your slimming effect will be. What you need is the most suitable sleep length. To find this length, you can try to go to bed 15 minutes earlier than usual until you find your ideal amount of sleep. Of course, it may take you a week to experiment, but it's worth a try.

The expert's advice is that if you want to lose weight, you should sleep at least 7.5 hours a day. Sleep an hour or two later than usual on weekends, and get up an hour or two later the next day.
