Objective: The aim of the study was to assess weight loss outcomes among participants (N = 1090) of a weight management program across multiple worksites (N = 10) in a retrospective analysis.Methods: Weekly classes focused on diet, exercise, and behavior change. One employer provided incentives for weight loss and two incentivized weight loss and class attendance. Results: Mean weight loss (N = 1090; 79.3% female) was -2.9% (SD = 3.0%). Average number of classes attended was 6.87/10 (SD = 2.9) and was significantly correlated with percent weight change (r = -0.46; P
