In a study of the caloric and protein requirements of children we have noted the well established phenomenon of a lowering of the basal metabolic rate with submaintenance diets. It was our plan to arrive at requirement figures by starting at admittedly low levels and increasing the intake to a point at which there was not only growth, as shown by increased weight and height, but a positive nitrogen balance as well. Because of the indications of a relationship between intake and the basal metabolic rate, the diets were then increased to the maximum intake, and an attempt was made to determine whether variations in the intake of protein affected the level of metabolism or whether the total caloric intake alone was the deciding factor.
PLAN AND METHODS OF STUDY
The study extended over three years. The subjects were thirty-three children, who were maintained on measured diets for periods averaging
