Eating less at late night is helpful in reducing concentration and alertness deficits that accompany sleep deprivation, revealed a study conducted by University of Pennsylvania School of Medicine.
The study explained that refraining from late-night calories helps people in preventing some of the decline that they may experience otherwise in neuro-behavioral performance during sleep restriction.
David F. Dinges, senior author of the study, said, "Adults usually consume 500 additional calories during late-night hours when they are sleep restricted. The study found that adults who were chronically sleep restricted were required to compensate for decreased morning resting metabolic rate by reducing caloric intake or increasing physical activity to prevent weight gain."
Namni Goel, a co-researcher, said that their study suggested that reducing the number of calories consumed could help prevent that weight gain and some of the health issues that are associated with obesity.
