The biggest news for diet help is online access to weight loss programs. Two studies (2001 and 2003) in the Journal of the American Medical Association report success with Web-based diet plans, especially if the plans incorporate e-mail with behavioral advice and support.

Keep in mind, plenty of junk science is out there, but the sites that follow are among the tried and true.

  • A site that offers expert weight-loss and weight-management assessments, tools, and resources with private and community message boards.

    Staff: A team of registered dietitians, exercise physiologists, and therapists designed and maintain the site.

  • Members receive meal plans and can follow their eating and exercise progress. The site has plenty of information on diet, nutrition, and fitness. Members can access a community of fellow dieters through an online message board and online chats.

    Staff: The director of nutrition services is a registered dietitian.
