  • Data are means ± SEM. Percent BF, FM, and FFM were calculated from body density values using the Siri two-compartment model. Body density measurements were made via whole-body plethysmography in the postabsorptive state after a 12-h overnight fast. Muscle mass (MM) was estimated from 24-h urinary creatinine excretion.
