The researchers studied 43 first-year female students at their university during the 2006-7 school year, monitoring their subjects’ food consumption, physical activity levels, BMI and weight for year. Despite consuming more calories and sugar than off-campus students who weren’t on the school’s meal plan, the dorm residents also exercised more, perhaps because they were closer to campus facilities, and walked from the dorms to class instead of commuting by car, researchers said.
