An Innovative Care Model Integrating Mobile Health Support to Promote Weight Management in Adults With Overweight or Obesity

The objective of this clinical trial is to evaluate whether an innovative care model integrating mobile health (mHealth) support improves weight management in adults with overweight or obesity. The primary research questions are: (1) Does the intervention promote weight change at the 6-month follow-up? (2) Does the intervention enhance physical activity and encourage a healthy diet at the 3- and 6-month follow-ups? To address these questions, researchers will compare the intervention group with a control group to measure changes in weight, physical activity, and dietary habits. At baseline, all participants will complete a survey assessing demographics, body weight, height, central obesity, lifestyle, weight loss history, and expectations. The intervention group will receive a weight management program based on Ecological Momentary Assessment (EMA), incorporating risk-stratified health services, with follow- ups at 3 and 6 months. The control group will receive minimal intervention in the form of general health advice, with follow-ups at the same intervals.
