Little sleep and bad fats

Lack of sleep feeding.
Sleep can be a form of dieting. Very little sleep increases the chance of becoming obese, says a recent study. Humans burn fewer calories when sleeping, so it may sound contradictory that more sleep prevents weight gain. However, it was discovered that people who sleep four hours or less per night were 73% more prone to obesity, perhaps due to the effects of hormones in appetite.

The study conducted at Columbia University was presented at the annual meeting of the American Association for the Study of Obesity in Las Vegas. The study analyzed data from 18,000 people between 32 and 59 years of age who participated in a national survey conducted in the 80s. "But it has more to do with what happens to the human body when deprived of sleep with the amount of activity which has been submitted," said the doctor in charge of the study.

Apparently, lack of sleep is related to the reduction in the levels of the hormone leptin, which regulates appetite and weight and tells the brain how much energy is available in the body. As a result, then, the less sleep sends an impulse to the body to begin to eat and store fat.
