The Internet Can Help You Lose Weight

Researchers in Providence, R.I., have proven that the Internet is a losing proposition -- and even venture capitalists should be pleased.

A new study published in the Journal of the American Medical Association (March 7) shows that Internet-based programs can result in significant weight loss. That's good news for the more than 61 percent of overweight or obese Americans, including fat-cat investors.

Doctors at Brown Medical School/Miriam Hospital and the Virginia Polytechnic Institute compared two weight loss programs -- one provided information only, while the other involved a more structured behavioral intervention approach that included counseling. Between the two groups, 91 overweight adults were studied for six months.

The first group accessed a Web site that provided dietary and nutritional information and organized links to Internet weight loss resources.

The second group, in addition to information and resources, received 24 weekly lessons via e-mail, submitted weekly self-monitoring data, and could participate in a bulletin board for participants to exchange information and support. (Self-monitoring data was reviewed by therapists who provided individualized recommendations, reinforcement and improvement strategies.)

Results showed that the behavioral intervention group lost more weight than did the information-only participants. The authors concluded that "the Internet appears to be a viable method for delivery of structured behavioral weight loss programs."

When choosing your own Internet-based program, look for these key elements of weight-loss success:

• Access to information and tools
• Structured behavioral components
• Weekly contact and feedback from a professional
• Peer support and e-mail outreach
