a None of the group differences at baseline were statistically significant. b Derived from self-report. c Detailed results for the 0–12 month body fat changes for the entire study population were reported in Friedenreich et al. [23]. The results in this table pertain to 334 participants with body fat data at the 24-month follow-up. d Percent body fat was calculated as 100% × (fat mass/(fat mass + lean mass)).
