title: Accuracy of predictions of long-term energy needs.
abstract: Energy needs as estimated by various methods were compared restrospectively with actual energy needs of eleven subjects who participated in long-term metabolic studies. Eight methods were compared with actual energy needs. The most satisfactory were the Harris and Benedict formula, the Kleiber formula, and the Mayo Foundation Nomogram, with an additional percentage allowed for activity energy. Interviewing methods were the least satisfactory for estimating energy needs. None of the methods was satisfactory for long-term use with individuals, indicating the necessity of follow-up and adjustment when energy intake is externally controlled.
