Nitrogen measurements in Groups A and B over the course of the 7-day study. a nitrogen excretion, b nitrogen intake, and c nitrogen balance. Error bars are SD for means in the two groups at each time point. Nutrition requirements for Group A were guided by 24-h nitrogen excretion for the duration of the 7-day study using an upper limit of 1.2 g/kg/d for protein intake. Nutrition requirements in Group B were guided by nitrogen excretion then by an upper limit of 1.5 g/kg/d for protein intake combined with REE from day 5
