Lack of sleep can make you fat
Of course, sleeping well also requires getting enough sleep. Lack of sleep is undoubtedly a stumbling block to weight loss. A study by the University of Pennsylvania in the United States showed that people who slept less than 5 hours a night preferred foods high in calories, fat, and sweets. These sleep-deprived people gained nearly one kilogram more weight in 5 days than the control group who got enough sleep.
Another study shows that people who sleep less than 6 hours a night are more likely to become obese than those who sleep 7-9 hours a night. This result is not difficult to understand, because lack of sleep is a kind of physiological stress for the body. In order to cope with the stress, the adrenal cortisol will rise and increase blood sugar. If these sugars are not consumed in a short period of time, the body will store the excess energy in the form of fat. In addition, when sleep is insufficient, ghrelin secretion increases and leptin secretion decreases. Appetite cannot be effectively controlled by willpower alone!
