After denying it for the past few years, I finally decided that I need to start dieting. When I was younger (all the way up until college, actually) I had the metabolism of a speeding train. I could eat ANYTHING I wanted and I never gained a pound. I was young, healthy, very skinny, and always active. And then I discovered one of the crushing realities of adulthood: if you are like most people, you sit at a desk for 8 hours a day, only getting up to go to the vending machine or the bathroom, where you sit on the toilet, quietly crying at the direction your life has taken.
