Outdated low-calorie fare, heralding melons as the new super diet helper. Though Neeb worked all this out on overweight Annapolis midshipmen, it's the once-standard calorie-counting regimen that has been much improved on elsewhere in the last five years. Neeb explains the basic rules (900-1200 calories on 3-meals-a-day) and recommends the usual behavior-modification measures (eat slowly, at the same time each day, only when sitting down, etc.). Exercise is endorsed; tips for difficult situations include spartan ordering in restaurants. (""Go out and have fun. . . order broiled chicken or fish and salad with vinegar only. Order a baked potato. When it arrives, scoop out all the potato and eat only the skin. . ."") Melon is included at each meal--""cabbage melon salad,"" for one--because it is tasty, nutritious, and, Neeb feels, will keep dieters from feeling deprived. Luckily, there are many more enlightened guides available.
