Body composition, especially regarding changes in cell hydration, was studied in severely undernourished adult males to assess changes during nutritional repletion. A low (26 g/day) protein diet providing adequate calories was consumed for 45 days. Body fat content increased significantly while cell hydration decreased. Protein repletion (100 g/day) led to a further decrease in cell hydration and a marked increase in body cell mass. Muscle cell mass increased more rapidly than nonmuscle cells, especially red cells. With repletion, the changes in the absolute values for plasma volume were significant, but those in extracellular fluid volume were not. Thus, the major compositional changes observed occurred in the body fat and the body cell mass components; these occurred independently of each other.
