Weight loss trajectories. Weight loss trajectories represent a two‐cluster, cubic model, determined from latent class growth mixture model. Each color represents an individual participant in the study. Within the weight regainer group, average weight loss (95% CI) was 4.8% (4.2%, 5.4%) at 3 months, 5.9% (5.1%, 6.7%) at 6 months, 5.5% (4.6%, 6.5%) at 9 months, 4.7% (3.7%, 5.7%) at 12 months, 3.3% (2.2%, 4.4%) at 15 months, 2.3% (1.2%, 3.3%) at 18 months, and 1.2% (0.1%, 2.3%) at 24 months. Within the weight loss maintainer group, average weight loss (95% CI) was 8.4% (7.2%, 9.6%) at 3 months, 12.2% (10.5%, 14.0%) at 6 months, 14.6% (12.6%, 16.7%) at 9 months, 15.9% (13.8%, 18.1%) at 12 months, 16.7% (14.6%, 18.8%) at 15 months, 15.9% (13.9%, 18.0%) at 18 months, and 14.0% (11.1%, 16.8%) at 24 months.
