App and Body Fat Scale in the Management of Overweight Patients
Trial Parameters
Brief Summary
This study tests whether using a health app (Huawei Health) and a smart body fat scale can help overweight patients with schizophrenia or bipolar disorder lose weight and stay engaged in their health. What We're Testing: 1. Patients who use the app and scale for 4 months (Group 1) will lose more weight than those who use them for 2 months (Group 2). 2. Patients who track their weight, diet, and exercise regularly (≥3 times/week) will lose more weight than those who don't. 3. Seeing weight loss results may motivate patients to keep using the app and scale. How It Works: Patients weigh themselves weekly with the scale (auto-syncs to the app) and upload dietary log in Huawei Health app. The app will gives personalized diet/exercise tips and tracks progress. Doctors and nutritionists provide extra support through messages. Goal: To see if this digital tool + professional support combo works better for long-term weight management.
