I have read all of those above except the chicken soup one, and I agree that those are all great choices. I loved Animal, Vegetable, Miracle! I love anything by Michael Pollan. The End of Overeating is very enlightening, for sure.
The books that have made the most difference to me - in terms of very practical techniques - are:
The Thin Commandments
The Beck Diet Solution - I'm going to buy that one. I prefer the pink book to the green one, but they both contain approximately the same information. Behavioral skills to help you succeed on any diet plan.
