Every once in a while you hear that the caloric theory has been exploded. There is no caloric "theory." Therefore none to explode. Calories are simply units for measuring heat and energy and never will be exploded any more than the yard or meter "theory" will be exploded. Foods must contain essential salts and the growth and health maintaining elements. These cannot be measured by calories. The quantity of heat or energy production but not the quality of the foods is measured in calories, and one must have a knowledge of the qualities also. No scientifically educated individual has ever thought otherwise. The chief objection to following the advice of the numerous laymen who write eat-and-grow-thin menus is that they advise the elimination of all fats, sugars and starches. They lose sight of the fact, or they do not know, that the obese individual--I dislike that term--will have to have a balanced diet even while reducing if he is to maintain his health. One will lose weight on these menus, but as very many can testify they lose their health also. One cannot live on an unbalanced diet for any length of time without becoming unbalanced also. And furthermore the over-weighter will always have to diet more or less, and will have to have menus which he can continue to use. After normal weight is reached he will not have to be nearly so abstemious, _but_ the same dietetic errors which produced overweight in the first place will produce it again. So he must know something of dietetics and he must have a balanced diet. Now I shall make out some balanced menus, 1200 C's a day, being careful to include a large amount of the leafy vegetables and some milk or its products, the foods that McCollom calls PROTECTIVE FOODS because they contain in a large measure the essential mineral salts, and those vital elements he has called "Fat soluble A" and "Water soluble B"--others call vitamines--which he has proved to be so vital and necessary for growth in the young and the maintenance of health in the adult. I shall also include 200-300 C's of protein. The leafy vegetables, cabbage, cauliflower, celery tops, lettuce, onion, Swiss chard, turnip tops, and other leaves employed as greens, water cress, etc., not only contain these vital elements, but they also exert a favourable influence on sluggish bowels and kidneys. They are low in caloric value, hence are low in fat-producing properties, and can be consumed with indiscretion, properly masticated.
