Healthy eating

I like to eat chocolate and other bad food a lot. I am not addicted to sweets etc. I keep going back and forth between eaten bad food a lot and not eating bad. Also my weight keeps going up and down between 120 and 135. I am trying to keep my weight down. What is the name of a book that could help me stop eating a lot of sweets and other bad food but has nothing to do with being addicted to bad food?
