Data are means ± SEM. BMI, body mass index; LBM, lean body mass. Body fat, fat mass, and LBM were derived from skinfold thicknesses as described in the Methods.

^*Post-Loss mean is significantly different from Baseline, i.e., main effect for weight loss (time), p<0.05.

^†Post-Regain is significantly different from Post-Loss within the NOEX and EX groups, p<0.05; see Results for details of significant main effects and interactions.
