The purpose of this study is to develop and test an adaptive, individually tailored intervention to prevent weight regain in people who have intentionally lost weight. The main questions it aims to answer are:
* Is an adaptive intervention with tailored re-engagement support feasible for individuals following intentional weight loss?
* Does this intervention prevent weight regain after intentional weight loss?
Participants will:
* Complete a baseline assessment of body measurements
* Complete surveys on dietary intake, mental health, and physical activity
Participants will also engage in a 26-week program, which involves:
* Receive regular educational texts/emails
* Fill out weekly online survey check-ins
* Weigh themselves at least weekly on a scale provided by the study
* Some participants may receive health coaching during portions of the study.
* Assessments will be repeated for all participants at the end of the intervention period.
