The best way to keep the line might be getting a good night’s sleep, according to a study from the University of Colorado reported by the New York Times.


It’s been several years that researchers have found that adults who slept less than 5 or 6 hours per night are more likely to be overweight. Relayed a new study by the New York Times reports today that the link between the two can be more insidious than we thought before, Lose a few hours of sleep for several nights in a row could lead to weight gain immediately.


Researchers from the University of Colorado have recruited 16 men and women healthy experience for two weeks. The objective was to determine how the lack of sleep over a week – like what might happen when students block for exams or when employees go to bed late to meet a deadline – can affect the weight of a person’s behavior and physiology.

During the first week of study, half of the participants were able to sleep nine hours, while the other half had to stay awake until midnight and could then sleep until 5:00. They all had unlimited access to food. The second week, the roles were reversed.

The researchers, at first, found that staying awake until midnight and sleep only five hours increased metabolism of those surveyed who have burned a hundred calories more per day. But staying awake is not a good way to lose weight. Short sleepers have ended up eating a lot more than others and at the end of the week they took on average one pound.


During the second week study, the group that had previously slept nine hours also gained weight when his sleep was restricted. The other group that was able to rest more began to lose some of the weight gained during the first week, but not all.


The researchers found a change in behavior among those who slept less. Not only leads to sleep late eat more, but also to eat differently. Thus, we tend to eat more carbohydrates, eat less at breakfast and much more after dinner. The researchers also found that lack of sleep disturbed the internal clock as a time difference.
