WORK AND FOOD REQUIREMENT. 939
As more work requires an increase in the absolute quantity of food,
so the quantity of food must he diminished when little work is performed.
The question as to how far this can be done is of importance in regard
to the diet in prisons and poorhouses. We give below the following as
example of such diets:
Proteins. Fat. Carbohydrates. Calories.
Prisoner (not working).. 87 22 305 1667 Schuster. 1
Prisoner (not working).. 85 30 300 1709 Voit.
Man in poorhouse 92 45 332 1985 Forster. 2
Woman in poorhouse. . . 80 49 266 1724 Forster.
The figures given by Voit are, he says, the lowest reported for a non-
working prionser. He considers the following as the lowest diet for old
non-working people:
Proteins. Fat. Carbohydrates. Calories.
Men 90 40 350 2200
Women 80 35 300 1723
In calculating the daily diet it is in most cases sufficient to ascertain
how much of the various foodstuffs must be administered to the body
in order to keep it in the proper condition to perform the work required
of it. In other cases it may be a question of improving the nutritive
condition of the body by properly selected food; and there are also cases
in which it is desired to diminish the mass or weight of the body by an
insufficient nutrition. This is especially the case in obesity, and all the
dietaries proposed for this purpose are chiefly starvation cures, which
is readily apparent if we study such dietaries.
