Values are means ± SDs. Labeled means (in a row) without a common letter differ, P < 0.05. Protein dose ranged from 0.20 to 0.25 g/kg BM for T1, 0.26 to 0.33 g/kg BM for T2, and 0.34 to 0.64 g/kg BM for T3. ALM, appendicular lean mass; BM, body mass; HbA1c, glycated hemoglobin; LBM, lean body mass; T, tertile.
