Changes in resting metabolic rate versus changes in fat free mass. Correlation between the changes in FFM and RMR in both men and women from visit 1 (1999) to visit 2 (2006). The change in RMR was positively correlated with the change in FFM for men (r = 0.49, p < 0.001) but not for women (r = −0.08, ns). FFM = Fat Free Mass. RMR = Resting Metabolic Rate.
