I literally had to go through my kitchen and bag up all the stuff that wasn't healthy... I gave it away to an intern where I work! It's tough to do, but then when you really want something and it isn't there, it's so much easier to substitute a piece of whole grain bread with peanut butter on it! Another thing that works well for me with snacking is to think about the clothes I want to fit in. That definitely helped me lose weight for my wedding last spring! :-)
