Another part of this book just lept off the page and bit me on the nose, so I had to share it!
"...I recommend that you should not even try to eat a perfect diet. Perfectionism is just a form of rigidity. It's simply compulsive "not eating," and it's usually replaced with compulsive eating after it become too unpleasant. Your real goal should be to overcome compulsiveness of any kind. To overcome compulsiveness, don't try to be perfect -- try to be good. Over the long run, good beats perfect every time" (The False Fat Diet Elson M. Haas, M.D.)
