Assessment

Primary outcomes

Percentage weight regain from discontinuation of incretin based antiobesity therapy to 12 months after discontinuation.
Percentage weight regain will be calculated as: ((body weight at 12 months after discontinuation - body weight at discontinuation)/body weight at discontinuation) times 100 (%).

Key secondary outcomes

1. Percentage of weight lost during incretin-based anti-obesity therapy that is regained at 12 months after discontinuation.
2. Proportion of participants with >=5% weight regain from body weight at discontinuation at 12 months after discontinuation.
3. Proportion of participants who regain >=25% and >=50% of the weight lost during incretin-based anti-obesity therapy at 12 months after discontinuation.

Interventions/Control_1

Intensive behavioral intervention group: Participants will receive outpatient follow-up and nutritional counseling every 4 weeks for 12 months after discontinuation of incretin-based anti-obesity therapy. In addition to standard nutritional and lifestyle counseling, the intensive behavioral intervention will include self-weighing, self-monitoring of dietary intake and physical activity, individualized goal setting, assessment and feedback on goal attainment, problem-solving support, and behavioral plan adjustment in response to weight regain.

Interventions/Control_2

Standard intervention group: Participants will receive outpatient follow-up every 4 weeks for 12 months after discontinuation of incretin-based anti-obesity therapy.
