Lack of sleep will seriously affect the balance of hormones in women, disturb women's digestive system, increase food intake, increase fat storage, and eventually lead to overweight or obesity. Among people who sleep less than 5 hours a day, overweight people are far more than those who sleep normally by 30%. During deep sleep, the brain will quietly secrete a large amount of growth hormone, guiding the body to convert fat into energy. If you reduce the deep sleep time and accumulate a lot of calories that can be converted into fat, the secretion of hormones can't keep up with the accumulation of calories, and your body will automatically convert these fats into buttocks, thighs and stomach. That's how obesity comes from.

Lack of sleep will not only increase hunger, but also lead to lack of energy during the day, affecting normal work and quality of life. Moreover, people who sleep for 5 hours or less are more likely to die of cardiovascular diseases than those who sleep moderately. Therefore, abstaining from sleep can not only lose weight, but also lead to other diseases.

The best sleep time for dieters is 7-8 hours. The general rule is to sleep at night 10, get up at 6 am and exercise, and don't sleep at noon. After food enters the gastrointestinal tract, it takes about 4 to 5 hours after eating to be completely emptied. Most families have dinner from 6 to 7 o'clock, and it takes about 4 hours to get to 10, and the food is basically empty. Sleeping at this time will neither store calories nor make them feel hungry. The sleep process only needs very low energy.
