Can lost sleep lead to wieght gain?

This was a interesting article to me because so many people in this day and age are worried about weight gain. I also saw that this was a article in the New York Times, which is the other reason why I was drawn to this story. For years researchers have known that adults who sleep less than five or six hours a night are at higher risk of being overweight.
In the begging of the article they talk about the University of Colorado's sleep researchers, took 16 people to experiment on about whether or not lost sleep can lead to weight gain. This study actually showed that people who are sleep deprived, lost an extra 111 calories a day whereas people who got a good nights sleep   did not lose anything.
Although the study did say that you lose weight, researchers did advise people not to stay up all night, just to lose weight. Not only that but it was shown that people who were sleep deprived, ate more calories than people who got a good nights sleep.
Even though losing sleep  lost weight was proven, Tara Parker-Pope said "Both Drs. Wright and Brady noted that because their studies lasted only days, it was not clear how long-term sleep deprivation affects weight, and whether the body adjusts to less sleep." So until further research is done, no one is really sure of whether lost sleep can lead to weight gain.
