Obesity greatly increases the risk of heart failure, and current treatments like caloric restriction, exercise, medications, or surgery may not be suitable for obese patients with heart failure. This research aims to study whether a combined approach using a diet management app and an intelligent weight scale can help obese patients with heart failure and reduced ejection fraction lose weight and improve their heart condition. The trial compares the effectiveness of a fully functional app and scale versus a limited-function version to assess their impact on heart failure outcomes and overall quality of life. Participants are randomly assigned to two groups one using a fully featured diet management app and intelligent weight scale with various monitoring tools and health metrics, and the other using a limited version of both. The full app tracks food intake, exercise, weight, and provides dietary analysis and recommendations, while the full scale measures body composition and vital signs. The limited versions offer fewer features. Participants use the app at every meal and weigh themselves daily for 12 months. During the study, participants will visit the clinic at 12 months for checkups. Researchers will evaluate outcomes such as a composite of death and heart failure hospitalizations over one year, changes in quality of life related to heart failure, and weight change. The trial includes monitoring of heart failure frailty and quality of life assessments at baseline, 3 months, and 1 year, with ongoing safety and condition tracking throughout the study period.
