The worst form of obesity, however, is that caused by overconsumption of fermented wines or malted liquors. This form of enlarged tissue contributes no strength whatever to its own support. It is as much of a dead weight as a hod of mortar, and much more useless; in fact, all forms of obesity are not only useless weight, but dangerous to life. The obese body is much more liable to contagious and infectious dis-eases, and when once affected, less able to defend itself than the normal body. OBESITY--THE REMEDY The control of body-weight rests upon three distinct and separate laws, the first and most important of which is nutrition, the second exercise, and the third oxidation. [Sidenote: The storing of fat regulated by labor or activity] While at the outset body-weight may be controlled by increasing the amount of activity sufficiently to use the surplus which Nature is storing away, if however, the activity ceases and the surplus is not used, then the storing process becomes chronic, and radical remedies both in regard to dietetics and activity must be applied in order to bring the body back to normal. [Sidenote: Amount of fat required daily in different climates] A man of normal weight, say 150 pounds, doing ordinary work in a tropical country, would not need to consume more than an ounce of fat each twenty-four hours, while the same man in a northern climate, where the thermometer ranges from zero to 20 below, could use up, with similar labor, from three to four ounces of pure fat daily. Fats, however, do not produce fat in the human body unless taken largely in excess of its needs. Their primary purpose is to keep up the temperature of the body. [Sidenote: Dietetic suggestions for chronic obesity] Where the weight is only from ten to fifteen pounds above normal, a substantial reduction can be made by merely balancing the diet, but where the accumulation of adipose tissue has become chronic, and the body has taken on from twenty to fifty pounds, or more, above normal, then a diet composed largely of non-acid fruits and fresh vegetables should be adopted for a period of from twenty to thirty days. [Sidenote: Foods that produce fat] Carbohydrates, that is to say starch and sugar, are the principal fat-making nutrients, and all people inclined to take on abnormal weight, as a rule, are very fond of, and eat an excess of starchy foods. A great amount of the casein in milk and the phosphorus in eggs are converted into fat, especially if a quantity be taken in excess of the amount used in effort or work. The fat-producing staple foods are: All cereal products All legumes Bread Eggs Milk Potatoes In order, therefore, to remove the causes of obesity, one must begin with the diet.
