Adherence

Web-based interventions that include enhanced features such as behavioral therapy, human email counseling, or automated feedback achieve significantly greater weight loss compared to education-only web-based programs or control groups.

If you use a web-based weight loss program, choose one that offers more than just information. Look for programs that provide personalized feedback, behavioral therapy, or regular contact with a counselor. These 'enhanced' features are key to achieving greater weight loss compared to basic educational websites.

There was a significant difference in the change in weight between the two groups post-intervention, with a greater decrease in weight in the web-based programmes with enhanced features (WMD 2.24 [1.27, 3.21] Z = 4.54 [P < 0.00001]).
