A light breakfast is advisable; one or two poached eggs, no sugar, bread and butter in small quantity. For dinner, choice may be made of chicken, game, lean meat, fish not cooked in fat, in moderate portions, and of such vegetables as celery, spinach, sea-kale, lettuce, string beans, cucumbers, carrots, tomatoes, cabbage, Brussels sprouts, turnips, bulky vegetables of low food value. Tapioca or similar pudding may be used for desserts, and melon, and other cooked unsweetened fruits. A glass of hot water on retiring is advisable. It is surprising what an enormous fuel value certain foods have which are eaten very carelessly, and what a very low fuel value others have which are quite satisfying to hunger. For example: One would have to eat $9.00 worth of lettuce and tomato salad to furnish 2,500 calories, the amount of fuel for the day's requirements (Lusk), while about 30 cents' worth of butter, or 10 cents' worth of sugar would furnish the same amount of energy. No one would think of feeding exclusively on any one of these foods, but it is easy to see how the elimination of butter and sugar and the introduction of such foods as lettuce, tomatoes, celery, carrots, spinach and fruits, all of which have a low fuel value, would enormously reduce the available energy and therefore the fat-forming elements in the diet, yet fill the stomach and satisfy the hunger-craving. Hunger is largely dependent upon the contractions of the empty stomach and not upon a general bodily craving for food. [Sidenote: Fat Forming Foods That Should, as a Rule, be Avoided by Overweights] Foods to avoid, in cases of overweight, are sugar, fats, milk as a beverage, salmon, lobster, crabs, sardines, herring, mackerel, pork and goose, fat meats, nuts, butter, cream, olive oil, pastry and sweets, water at meals. Alcohol, which is not a food, although often so called, should be avoided, as it is a fuel. It is good to burn in a stove, but not in the human body. [Sidenote: Exercise for Overweight] Walking, swimming, golf, billiards, hill-climbing, are all beneficial forms of exercise for the middle-aged and elderly, who are chiefly affected by overweight. Irksome and monotonous forms of exercise, while difficult to follow regularly, are usually of more benefit, as they are less likely to create an appetite. Simple exercises, if repeated from twenty to forty times, night and morning, will accomplish much. No apparatus is required, and any movements that bring into play the entire muscular system, and especially the muscles of the trunk, with deep breathing, are sufficient. (See "Setting-up" exercises described in the "Notes on Posture," page 221.) The main reliance should be upon dietetic regulation rather than upon exercise. A very moderate increase of exercise and a persistent adherence to a proper diet will work wonders in weight reduction. [Sidenote: Avoidance of Sudden Reduction]
