I've made a few simple changes to my diet that I think have been very helpful. I don't eat any less, I just eat "smarter". For example, I will often make myself a bowl of popcorn (air popped) for an evening snack and I will not add salt or butter. I try and read labels and do my best to minimize high fructose corn syrup. I try and eat whole grains as often as possible instead of refined flour. I eat lots of fruits and vegetables. My snack/dessert of choice is Kashi Go-Lean Crunch cereal.
