Adherence
Adding personalized e-feedback and reminder calls to a basic commercial web-based weight loss program does not result in greater weight loss or BMI reduction compared to the basic program alone after 12 weeks.
You do not need to pay for enhanced features like personalized feedback or reminder calls to lose weight. The basic program is sufficient for weight loss. Enhanced features might help you stay in the program longer, but they won't make you lose more weight in the first 12 weeks.
GoodRefutesHIGH confidence
Although the provision of additional personalized feedback did not facilitate greater weight loss after 12 weeks, the impact of superior participant retention on longer-term outcomes requires further study.
Why this rating
RCT design, clear negative finding for the specific comparison.
