Why you might pack on pounds If college is your first time away from home, it's probably your first shot at choosing your own meals. And while mom may have said no to pizza for breakfast, lunch, and dinner, she's not there to stop you from overeating at the all-you-can-eat cafeteria. Combine that with late night food deliveries and snacking during study sessions, and it's hard to believe that the freshman 15 isn't more like a freshman 50.
