Mean changes in body weight during the randomized crossover trial and 12‐month post‐trial follow‐up. Dashed lines: body weight changes during the randomized crossover trial; Solid lines: body weight changes during the 12‐month post‐trial follow‐up. Group A (black boxes) first participated in the 3‐month weight reduction program, and underwent post‐trial follow‐up for 12 months without any additional interventions. Group B (white boxes) first underwent a 3‐month observational period before participating in a delayed intervention of the same 3‐month weight reduction program. Group B then underwent post‐trial follow‐up for 12 months without any additional interventions. The error bars indicate the 95% confidence intervals of each mean weight change
