Active Comparator: Behavioral Weight Loss + Text chat
Internet delivery of a behavioral weight control program via text in a group format facilitated by an experienced registered dietitian. Participants will have access to study materials including behavioral weight loss lessons on the study's website. Participants will weigh themselves daily and report their weight privately (data will only be accessible by research personnel) on the study website.
Behavioral: Behavioral Weight Loss + Text
Participants will attend weekly one hour classes on line. They will type their input and responses within the chat room. They will record their calorie and fat intake daily and weigh themselves daily. Interventionists will review the diaries weekly and provide feedback to reinforce or shape new behaviors and to identify high risk situations for problem solving.
Experimental: Behavioral Weight Loss + Video chat
Internet delivery of a behavioral weight control program via video in a group format facilitated by an experienced registered dietitian. Participants will have access to study materials including behavioral weight loss lessons on the study's website. Participants will be given smart scales to weigh daily, and weight will be transmitted to a secure website accessible only by research personnel.
Behavioral: Behavioral Weight Loss + Video
Participants will attend weekly one hour classes on line. They will have audio and video within the chat room, and will talk with their facilitator and classmates during their weekly meeting. They will record their calorie and fat intake daily and weigh themselves daily. Interventionists will review the diaries weekly and provide
- Weight loss from baseline [ Time Frame: baseline, 2 months, 6 months ]The investigators will assess weight change differences between subjects randomized to receive an internet program alone with text chat vs. an internet program with visual chat and bodytrace smart scales. Weight will be assessed at baseline, 2 months after intervention begins, and at the end of intervention using a calibrated digital scale (Tanita, WB800S) with subjects in street clothes, without shoes.
- Attendance at chat [ Time Frame: 6 months ]The group facilitator will record attendance at chats. Attendance at chat will be compared by treatment arm. Rate of attendance is calculated as number of meetings attended out of a total possible 24 meetings over the course of the study.
- Self monitoring dietary intake [ Time Frame: 6 months ]Number of weekly journals submitted out of a possible 24 weeks total will give the investigators the rate of self monitoring. Rates of self monitoring will be compared by treatment arm.
- Self monitoring weight [ Time Frame: 6 months ]Number of daily weights submitted over the course of 24 weeks divided by the possible total of weights will give the rate of weight self-monitoring (7/week x 24 weeks = 168 possible weights). The VIDEO arm will be provided with BodyTrace electronic scales that report weight to a secure database via cellular connectivity. Subjects in the TEXT arm will report their weights to their facilitator using their own digital scale at home.
