Query: The difference between cravings and hunger

I have craved carbs for 36 years, since I was 12 and started eating to cover up my feelings. This book has helped me overcome my fear of hunger, because hunger is easy to handle-- the cravings are not. By eating carbs once a day, I feel hunger sometimes the rest of the day, but I can hold on for an hour or two until my next meal. I could never control a craving -- I had to eat, and beat myself up everyday for being "weak" and not losing the 30 pounds I gained when I quit smoking. I think this diet is a solution to my problem, and I'm very grateful.
