Fourteen healthy, non-obese subjects between the ages of 18 and 30 participated in the study. Is this a representative sample warranting this level of attention? Subjects who were deprived of sleep said that they felt hungrier, and had more trouble controlling themselves when faced with the snacks. They ended up consuming nearly twice as much fat and protein as the control group. So people who were awake more ate more. This would seem to make sense - I have literally never eaten while I was asleep.
