Ravelry: discussion topic - How to stop "Grazing"?: "I read a book on compulsive eating once - can’t remember for the life of me what it was called! - and the key message was to 1. plan when you are next going to eat, anywhere between in 30 minutes to 4 hours time. If you get to that time and you’re not hungry, fine - just set another time. It advises against going for more than 4 hours without eating though. Then 2. when you do get to the ‘set’ time, decide beforehand what and how much you are going to eat. You may eat less, if you get halfway through and feel full up for example, but never more. Then go back to step one and decide what time will be your next eating opportunity…and so on and so forth."
Hmm - would that work?
