Extract: An experiment was conducted to determine nitrogen (N) balance and the energy intake needed to support it when supplementary N was added to a diet containing 0.57 g of egg protein/kg/day. Four young men, 20 to 21 years old, participated in the 58 to 79 day metabolic N balance study. The energy intakes predicted to maintain N balance were approximately 10 to 15 percent less than the requirements estimated from body weight and N balance data. Present results, although based on a limited number of subjects, suggest that total N may be the limiting factor in short term N balance at the 1973 FAO/WHO egg protein intake level for a significant proportion of young adult male populations.
