Instead of Ideal Weight, you might want to try New Behavior Generator. Now, I must warn you that most "diets" out there have a 98% failure rate because THEY STINK. Low-fat diets are the result of "magical thinking," e.g. "If I don't eat fat, the fat will go away." Ketogenic diets work better, but they have their own set of problems (cost being a big one).
So far, the best diet I've found is "Neanderthin," which deals with food addiction by cutting out those foods which are most addictive. I've lost over 100 pounds on this diet alone, with NO mental tricks other than those the author used in his Third Edition book to link the diet with one's religious memes.
