According to a study from the University of Chicago, while we are on a diet to lose weight, sleeping through the night causes more fat to be lost . Specifically, if we reduce our sleep to only 5.5 hours, we lose the same weight as after a sleep of 8.5 hours, but the burning of fat is reduced by half.
The differences are due to the fact that, when sleep is restricted, levels of ghrelin increase , a hormone that stimulates hunger and reduces energy expenditure, in addition to "promoting fat retention," according to Plamen Penev, director of the study.
"For the first time, we have evidence that the number of hours of sleep can make a difference in the result of a weight loss diet ?, says Penev. And he adds that? If your goal is to lose fat, skipping hours of sleep is like puncturing wheels of your bicycle ?.
