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.

RECRUITINGFeasibility - Participant Retention
Number of participants who continue to participate for all 26 weeks of the study and complete all study activities
Time frame: From enrollment to the end of the 26-week monitoring period
Feasibility - Participant Adherence
Number of participants who complete all study activities, including weekly weigh-ins, weekly surveys, and pre/post study visits.
Time frame: From enrollment to the end of the 26-week monitoring period
Efficacy - Participant Weight
Time frame: From enrollment to the end of the 26-week monitoring period
Efficacy - Participant Dietary Intake
Dietary and nutritional data collected via self-report using the ASA24 (Automated Self-Administered 24-Hour Dietary Assessment Tool). This includes calories, protein, fats, and other nutrition information based on participant self-report of meals.
Time frame: From enrollment to the end of the 26-week monitoring period
Efficacy - Eating Self-Efficacy in High-Risk Situations
Eating self-efficacy in high-risk situations will be measured pre- \& post-intervention using the Weight Efficacy Lifestyle Questionnaire.
Time frame: From enrollment to the end of the 26-week monitoring period
Efficacy - Eating Behavior Patterns
Eating behavior patterns will be measured pre- \& post-intervention using the Three-Factor Eating Questionnaire.
Time frame: From enrollment to the end of the 26-week monitoring period
Efficacy - Sleep/Rest Duration
Sleep/rest duration will be measured in hours/day using the activPAL accelerometer, a thigh-worn device that objectively measures posture and movement. Participants will wear the device continuously for 7 consecutive days.
Time frame: From enrollment to the end of the 26-week monitoring period
Efficacy - Daily Step Count
Daily step count will be measured using the activPAL accelerometer, a thigh-worn device that objectively measures posture and movement. Participants will wear the device continuously for 7 consecutive days.
Time frame: From enrollment to the end of the 26-week monitoring period
Efficacy - Sedentary Behavior (Sitting/Lying Time)
Sedentary behavior will be measured in hours/day using the activPAL accelerometer, a thigh-worn device that objectively measures posture and movement. Participants will wear the device continuously for 7 consecutive days.
Time frame: From enrollment to the end of the 26-week monitoring period
Efficacy - Standing Time
Standing time will be measured in hours/day using the activPAL accelerometer, a thigh-worn device that objectively measures posture and movement. Participants will wear the device continuously for 7 consecutive days.
Time frame: From enrollment to the end of the 26-week monitoring period
