Previously, it was known that lack of sleep has a negative effect on the metabolism. Investigation Kelly Ness, a graduate of the University of Pennsylvania, revealedHow quickly thus deteriorating the absorption of fat - and saves whether long sleep on weekends.
The study involved 15 men aged 20-30 years. First they slept for a week in normallyAnd then spent 10 nights in the sleep laboratory. Five of them, they slept only 5 hours. For dinner, they received a meal high in fat - and chili paste. The food was delicious, but very high-calorie.
Most of the subjects reported that they received less pleasure from food than they eat something like that, but with proper sleep. Analysis of blood showed increased content of insulin - a hormone that is needed to penetrate the glucose from the bloodstream into cells. As a result, the body gets fat from food faster than normal - which leads to weight gain.
"The lipids are deposited, and not split, - explained Orfo Buxton, Lecturer University of Pennsylvania, who also participated in the study. - Although evolution is the storage of fat in the "rainy day" was an important survival mechanism, humans generally move a little in the developed world, and high-calorie and fatty foods to get very easy and inexpensive. "
Ness added:
Regular lack of sleep during the life increases the risk of obesity, diabetes and other metabolic diseases.
After the researchers simulated "otsypanie" experiment at the weekend: two days, the subjects slept for 10 hours. Although after the first night of their metabolism began to come back to normal, even after the second he has not recovered to its previous level. But this time was enough to bring back the original weight.
