Weighing in from swank Southhampton: a low-calorie, well-balanced diet, with interesting recipes, standard behavior-mod techniques, and a rah-rah biochemical solution to deprivation discomforts. The chief rub: causes of overweight ""are almost always psychological."" The Southhampton rattles Berger has been treating for years (after first losing almost 200 lbs. himself) don't go for middle-class diet foods, so the recipes are grouped into French menus (nouvelle cuisine included), Italian, Japanese, Chinese, Greek, Mexican, and Jewish menus--and include the likes of fish plaki and stir-fry shrimp with snow peas. The ""biochemical miracle""? Some foods (like chocolate--not recommended here) can alter moods--have calming or elevating effects. But since you're not supposed to feel hunger on this regimen, ""if you do experience what you interpret as hunger,"" you must determine if ""what you are feeling is not simply a patterned response to some external stimulus."" A good, balanced low-calorie diet, then--but given recent findings on the physiological bases of overweight, a dubious return to the guilt-trip approach.
