EXPERIMENTAL

Participants in the intervention condition are encouraged to access the Achieve Together website at least once each week. During each login, the following activities will occur: 1. Users will enter their weight and height, how well their plan for a healthy weight has been going, and clarify their goal weight. 2. Users will answer questions about each habit they are using to lose weight 3. Users will receive automated feedback about each habit and will be encouraged to change or delete habits that are being used but not helpful, more consistently use habits that are helpful but not used being used and to continue to use habits that are helpful and being used consistently. 4. Users are encouraged to search for habits that have helped people of similar age and gender to themselves.
