Optimizing Feedback for Overweight and Obesity Treatment

This study is looking at the best ways to give weekly feedback to people in a weight loss program. It's testing different types of feedback, such as comments on your calorie goals, dietary quality, physical activity goals, and prompts to set new goals. You could join if you are 18 or older, have a BMI (Body Mass Index) of 25 or higher, weigh 175 kg (about 385 lbs) or less, and own a smartphone compatible with Fitbit. The main goal is to see how these different feedback types affect weight change after 7 days. The study is currently unclear on its recruitment status and plans to enroll 300 participants.

Study design
This is an interventional study that aims to enroll 300 participants. It uses a micro-randomized factorial design, meaning participants will be randomly assigned to receive different combinations of feedback each week.
What's involved
You will attend a "Weight Loss 101" session to learn about weight loss and how to use tools to track your diet, physical activity, and weight. You will then receive weekly feedback messages based on your self-monitoring data.
Compensation
Not stated in the trial record.
Follow-up
Weight change is measured at 7 days, suggesting a short-term follow-up for this primary endpoint.

What this trial measures

  • Weight change7 days

    Fitted model values will then be used to estimate the slope of weight change from day 1 (the day a feedback message is received) to day 7 of each week, with positive values representing weight gain and negative values representing weight loss.
