What's already been posted is truth. "Starting over" just means you pick yourself up where you are and keep going. Nobody eats perfectly. In fact, I think it's a challenge to maintain...it's about lifestyle change rather than lose and go back to the old way of eating.
With that said, I've been eating Body For Life plan since 2002 (NOT perfectly) and find it very do-able.
Best of luck!
