This randomized controlled trial is comparing outcomes of customary Fit and Strong!, to Fit and Strong! Plus, an enhanced version of the program that incorporates weight management. We hypothesize that Fit and Strong! Plus participants will show improved diet behaviors at 2, 6, 12, and 18 months that will be accompanied by a significant 5% weight loss at 6 months and maintained to 18 months, compared to participants in customary Fit and Strong!.
