It's supposed to happen when you go to college. You're metabolism changes, and you inexplicably gain 15 pounds. I went all these years without this great misfortune, but I discovered a little over a month ago that I had, indeed, gained 15 pounds. With shock and horror I threw myself into healthier eating habits, but progress has been slow and often discouraging.
Losing weight is a bitch.
It should be against the laws of physics, that you can't gain weight any faster than you can lose it.
