Adherence
A 12-week commercial web-based weight-loss program produces statistically significant and clinically important weight loss and BMI reduction in overweight and obese adults compared to a wait-list control.
Use a commercial web-based weight loss program for 12 weeks. Expect to lose about 2-3 kg. The key is consistent self-monitoring (logging food and weight at least 4 times a week). Enhanced features like automated feedback may help retention but do not significantly increase weight loss over the basic version in the short term.
This study demonstrated that participation in either version of the 12-week commercial Web-based weight-loss program (standard or enhanced with feedback) resulted in statistically significant and clinically important objectively measured weight loss.
Why this rating
Randomized Controlled Trial with assessor blinding and intention-to-treat analysis, though limited to 12 weeks.
