Readers of the words of wisdom from the Herald-Tribune Home Institute have already learned about Dr. Joliffe's theory on the ""appestat"", that mechanism in the human body that controls the appetite, and that must be re-educated if a diet is going to bear lasting results. The rarity of organic disorders as a cause for obesity in comparison to the functional disorders for which overeating is largely responsible is duly discussed and weighed against the health hazards of obesity. The basic physiology, disposal of mistaken arguments against reducing, mathematical charts on how to estimate relation of speed of reduction to other factors, discussion of the nutritional needs, the necessity of certain elements in every diet, the importance of variety -- and how to obtain it -- all this leads up to the kernel of the book, calories -- and their relation to diet to maintain proper weight. This is no short cut, but a reasoned, scientific, and meticulously developed pattern of eating ""to reduce and stay reduced"". 72 menu plans will help the harried housewife to put the theories into practice.
