NCT07555730

Brief Summary

This is a randomized controlled trial to compare the effect of AI-assisted multi-domain lifestyle and continued tirzepatide on body weight loss maintenance. The study consists of two phases: a 20-week lead-in phase, during which all participants will receive weekly subcutaneous tirzepatide at the maximum tolerated dose (MTD), followed by a 52-week intervention phase. Participants who meet the randomization criteria after the lead-in phase will be randomly assigned to either AI-assisted multi-domain lifestyle intervention or tirzepatide 5 mg

Study Arms (2)

AI assisted multi-domain lifestyle intervention

EXPERIMENTAL

Participants will be randomized to receive multi-domain lifestyle intervention including diet, physical activity and psychological support for 52 weeks. Additionally, the weight loss maintenance program will integrate AI-assisted nutritional analysis to facilitate long-term weight management.

Behavioral: AI assisted multi-domain lifestyle intervention

Tirzepatide

ACTIVE COMPARATOR

Participants will be randomized to receive tirzepatide 5 mg treatment for 52 weeks.

Drug: Tirzepatide

Interventions

AI-assisted multi-domain lifestyle interventions that integrate dietary, physical activity, and psychological components.

AI assisted multi-domain lifestyle intervention

Administered subcutaneously.

Tirzepatide
