iOTA Text Messaging Intervention
There will be a 6 month "active" treatment phase consisting of monthly meetings with a study health coach to develop reasonable health goals and interactive text messaging to provide daily support and self-monitoring of behavior change goals between in-person visits. Participants may receive phone calls between visits from their health coach for additional support if needed. Following the active treatment phase, participants will receive daily health-related text messages for another 3 months. iOTA text messaging intervention: Over 6 months, participants in the iOTA arm will have monthly in-person visits with a health coach who will work with the participant to set goals for the upcoming month related to healthy eating and activity. The participant will receive daily text message health tips related to their goals, and will be prompted once a week to respond with a text indicating their weight and how they are doing with their goals. Following the 6-month active treatment phase, participants will receive text messages only for another 3 months.
Health Education Text Messaging Intervention
There will be a 6 month "active" treatment phase consisting of monthly in-person visits with a health coach to learn about healthy eating and activity behaviors, including developing readiness for health behavior change. Participants will not set specific health goals, but will receive weekly text messages about general health tips related to their in-person visits. Following the active treatment phase, participants will receive daily health-related text messages for another 3 months. Health Education text messaging intervention: Over 6 months, participants in the Health Ed arm will also have monthly in-person visits with a health coach who will provide education on energy balance and problem-solving. Specific goals will not be set, but the health coach will assist participants in problem-solving any challenges. Participants will receive a weekly automated motivational text message health tip from the study related to what they learned in their health coaching sessions. Following the 6-month active treatment phase, participants will receive text messages only for another 3 months.

SECONDARY outcome

Timeframe: Baseline and 24 weeks

Population: One patient missed/ skipped this session in iOTA group at baseline; Only 7 participants in Education group and 9 iOTA participant completed the 24 weeks follow-up.

This questionnaire includes 32 questions in two domains of self efficacy: 1) healthy eating and 2) exercise. Within it, there are 20 questions about the eating habits sub-scale and 12 questions about the exercise habits sub-scale. Respondents are asked to recall how confident they have felt in doing positive health behaviors since the last study visit. Responses are on a likert scale of 1 - 5 (1 - 2 = I know I cannot do; 3 - 4 = Maybe I can; 5 = I know I can). A total score is reported with a range of 32 to 160, where a lower score represents worse overall eating and exercise habits. Total scores is measured at baseline and 24 weeks follow-up.

SECONDARY outcome

Timeframe: Baseline and 24 weeks

Population: Time X treatment (0 and 24 weeks) with sum of the score

This questionnaire includes 10 questions, with three separate subscales: 1)Self-determination, 2)Cognitive control and 3)Interoceptive Awareness). Respondents are asked to rate their own skills since the last study visit. Responses are on a likert scale of 1-5 (1 = never, 2 = rarely, 3 = sometimes, 4 = often, 5 = always). Scores are generated for each subscale, as well as a total score. Total score is from 10-50. Higher scores indicate greater degree of psychophysical awareness \& skills.
