The in-flight caloric intakes of all Apollo astronauts are examined and shown to average about 25 kcal per kg per day. Measurement of weight changes following recovery indicates that about 0.15 kg of fat was lost per man per day in-flight for an average deficit of about 19 kcal per kg per day. Measurement of the caloric intake of astronauts under ground-based conditions and during hypobaric exposure indicated a caloric requirement which was not significantly different from the in-flight requirement adjusted for weight loss. Partial metabolic balance data and measurements of bone loss and body volume revealed that protein and mineral losses also occurred to an extent which would reduce the size of estimated in-flight caloric deficits.
