The Impact of Integrating an Internet Weight Control Program Into Primary Care

The investigators will conduct a randomized controlled trial comparing the effects of three interventions on weight loss at 12 months. The investigators propose to test the impact of integrating an effective automated Internet weight control program into primary care by recruiting patients and randomizing them to one of three conditions: A) Brief physician counseling plus usual care, B) Brief physician counseling plus referral and access to the Internet weight control program and, C) Brief physician counseling plus referral and access to the Internet weight control program plus brief follow-up email notes of support and accountability from Primary Care Physicians. The investigators hypothesize that an online program for weight control can be more effective by enhancing online follow-up with PCPs.
