Overview
Brief Summary
Project ReLearn is testing the efficacy and cost-effectiveness of an Artificial Intelligence system for optimizing weight loss coaching. Participants are randomized to a 1-year weekly gold standard behavioral weight loss remote (video) group treatment or the AI-optimized treatment, which is made up of a combination of remote group treatment, short video call and automated message. In the AI-optimized condition, the system monitors outcomes (via wireless scale, mobile phone app, and wristworn tracker) and, each week, assigns each participant the treatments they have responding to the best, within certain time constraints.

Eligibility Criteria
Inclusion Criteria
- •Individuals must be of overweight or obese BMI (27-50 kg/m)
- •Individuals must be adults (aged 18-70)
- •Able and willing to engage in the remote program
- •Able to engage in physical activity (defined as walking two city blocks without stopping)
- •Individuals must also provide consent for the research team to contact their personal physician if necessary, to provide clearance or to consult about rapid weight loss
- •Access and willingness to use an Apple or Android smartphone
- •Satisfactory completion of all enrollment procedures
Exclusion Criteria
- •Medical condition (e.g., cancer, type I diabetes, psychosis, full-threshold eating disorder) that may pose a risk to the participant during intervention or cause a change in weight
- •Currently pregnant, breastfeeding, or planning to become pregnant in the next 12 months

- •History of bariatric surgery
- •Weight loss of \> 5% in the previous 3 months
Outcomes
Primary Outcomes
Costs
Time Frame: Baseline, 1-month, 6-month, and 12-month assessment
All time spent training counselors, participants and supervising counselors, will be tracked by the project coordinator, as will time counselors spend delivering individual and group treatment. The web portal will track counselor time on the portal, e.g., reviewing food records and texting. While the basic time commitments are pre-set by condition, several factors will vary including participant no-shows, participant drop-outs, and counselor adherence to time limits.
Weight change
Time Frame: Baseline, 1-month, 6-month, and 12-month assessment
Weight will be measured using the Fitbit Aria Air wireless scale, which is accurate to 0.2 kg. In order to maximize accuracy, we will (1) provide instructions (e.g., place scale on flat, hard surface; weigh upon waking, without clothes, after using the bathroom), (2) require participants to confirm that they are following instructions at each assessment point, (3) use an average of 5 consecutive daily weights for each timepoint, (4) remove errant weights (e.g., \>1 kg change in 1 day).
Secondary Outcomes
- Calorie intake(Baseline, 1-month, 6-month, and 12-month assessment)
- Acceptability as Measured by Likert Self-report Scale(6-month and 12-month assessment)
- Physical Activity(Baseline, 1-month, 6-month, and 12-month assessment)
