All this expenditure of
energy and loss of heat must be made up for by the food intake. Only a
small amount of surplus food can be stored in the body. Some fat can be
stored as fat. Some starch and sugar can be put aside as either
glycogen--animal sugar--or be changed into fat. This storing of excess
food is very limited, except in cases of obesity, which is a disease.
Overeating invariably causes disease. It may take two or three years,
yes even twenty or thirty years, before the overeating results in
serious illness, but the results are certain, and in the meanwhile the
individual is never up to par. He can use neither body nor mind to the
best advantage.
To emphasize and illustrate these remarks, I shall copy a few diet
lists, which their authors consider reasonable and correct for the
average person for one day, and I shall give my comments. The first is
taken from Kirke's Physiology, which has been used extensively as a
text-book in medical colleges:
340 grams lean uncooked meat,
600 " bread,
90 " butter,
28 " cheese,
225 " potatoes,
225 " carrots.
An ounce contains 28.3 grams; a pound, 453 grams.
