缺觉使你变胖

Do you want to know why you are hungrier than usual if you do not get a good night's sleep? Researchers from the University of Chicago say they have found one reason. Their study shows that a lack of sleep makes people hungrier the following day. A lack of sleep produces chemicals in the brain that makes you feel like eating, which also makes us eat more. We want to eat food that is high in calories. The researchers found that a lack of sleep makes people eat sweets and biscuits far more than healthier foods. The researchers also reported that people in the study who did not get enough sleep ate up to twice as much fat as when they had slept for eight hours.

The study was going on 14 men and women in their twenties. They were studied by researchers in two different situations. In one, they spent 8.5 hours in bed each night and had 7.5 hours of sleep. In the other, they spent just 4.5 hours in bed and had 4.2 hours of sleep. The researchers found that in the first situation, the people ate three meals a day as usual. However, in the second situation, where they had been a lack of sleep, they could not stop thinking over and over delicious food. This happened just 90 minutes after they had eaten a meal that gave them with 90 percent of their daily calories.
