WASHINGTON, D.C. -- The Internet may be an effective weight loss tool.
A review of 14 studies finds overweight adults who participated in web-based weight loss programs lost more weight than those who were not enrolled in any program.
However, face-to-face classes were the most successful.
Experts say web-based programs still have the potential to impact thousands of people, because doctors can reach more patients when using the web compared to their office.
Another benefit is that web-programs are cost-effective.
This study is published in the Cochrane Database of Systematic Reviews.
