You can still enjoy the foods you love! However, it is better to do so once a week in a controlled cheat meal. This way, you can enjoy your favorite foods, without sabotaging the rest of the week. If you really fancy something have a little bit of it. It is about learning how to enjoy foods rather than abusing them and using them as your emotional crutch.
If you go over board, just get back on track, rather than continuing it for a week/month. Treat the weekends like any other day. Just because the days are labelled Saturday and Sunday makes no difference.
