I agree with everything Cassie wrote. I will add that it takes some time to figure out what works for you, but really, the idea is to improve your eating habits for life, not just long enough to lose a couple of pounds. So start with eliminating 1 bad habit at a time. Do you drink a lot of soda? Starting replacing the soda with water, iced tea, or other non calorie beverages.
FitDay really helped me figure out "trigger" foods. Those are the things that once you start eating it is hard to stop. Nuts, ice cream and potato chips are trigger foods for me, so those are things I really need to avoid.
As Cassie said, keep in touch - we are all in this together!
