Eating at night can lead to significant weight gain according to a recent study from Northwestern University in Evanston, Ill. Researchers fed one group of mice a high-fat diet during the hours when they normally would be sleeping, and fed another group of mice the same diet during their waking hours. The mice who ate during their nocturnal hours gained twice as much weight over six weeks as the other group.
Although this study was on mice, and may not be applicable to humans, previous studies have also found similar results. Simply altering the timing of eating, without necessarily cutting calories or increasing exercise, may be key to success in weight loss.
