Outcome Measures
Primary Outcomes (1)
Weight loss from baseline
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.

Study Arms (2)
Behavioral Weight Loss + Text chat
ACTIVE COMPARATORInternet 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 Weight Loss + Video chat
EXPERIMENTALInternet 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.
Interventions
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.
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
