Days of deprivation (ordinate) needed to produce the percentage decrease in body content indicated for each substance in individuals of various ages (abscissa). The rates of loss indicated for each substance approximate to physiological minimum output rates, of which some are indi- cated by the lower boundaries of the physiological tolerance ranges shown in Fig. 2. rate of loss was taken as the physiological minimum require- ment value indicated in Fig. 2. In considering body fat (calorie) stores, energy expenditures were assumed to be at the rate of 1,800 calories per m.^ per day (Macy, 1942) and to be derived entirely from body fat. Body protein losses were calculated assuming a basal rate of loss amounting to 25 g. per per day, the minimum value attained by individuals.
