I lost weight basically by "eating like a grown up". I started to eat things like oatmeal and veggies and fruit and beans instead of Pop Tarts, frozen pizzas, mac and cheese, and Little Debbie cakes. It's amazing how much more full you feel when you eat a lot of fiber and whole foods. Although, I will admit that most of what I eat now can't compare with the taste of the processed food. I think it's so hyperpalatable that when you give it up for a while, when you eat it again it tastes so overly sweet and salty that you can't imagine why you used to like it.
