Sound advice on the dietary way to weight loss--with an update on dieting physiology. This Johns Hopkins program has a proven, ten-year track record; and here has been competently turned into a self-help regimen by Simonson, its director. The first step is to assess one's eating patterns (including responses to stress); then, the authors explain the common types of overweight (from organic and hormonal, to psychological, to added pounds accompanying added years) and look at the significant weight-related differences between men and women: not only do men lose faster, but society doesn't hold them to an equally strict standard. Simonson and Heilman next discuss the physiology of overweight: how the body adjusts to being obese and keeps itself that way, and how to overcome those adjustments. They also consider the psychological needs that food may fulfill--and how, once identified, those needs can be filled in other ways. The well-conceived diet itself allows for a certain number of portions from each food group daily, and sets up strict menus for those who need them. Unusually helpful tips on adhering to the diet include discussion of eating and weight-loss cycles and plateaus. Throughout, exercise is stressed as a primary means of readjusting the body's metabolism--though specific advice here is brief. Reliable and current--but not markedly different from several of its worthy predecessors.
