Summary

This trial will test whether giving people weekly incentives to monitor their diet and/or lose weight leads to better short- and long-term weight loss. The study will last 18 months.

Who is the study for?
This trial is for adults with obesity who want to lose weight. They must be able to stand unassisted, have a BMI of 30 or higher, speak and read English, own a smartphone with data and texting plans, have reliable internet access, and commit to attending study visits over an 18-month period.
What is being tested?
The study tests if small weekly incentives can boost dietary self-monitoring and weight loss effectiveness. Participants will use apps like MyFitnessPal and Fitbit daily while receiving these incentives for their progress over the course of the trial.
What are the potential side effects?
Since this trial involves lifestyle changes rather than medication, side effects are not typical as in drug trials. However, participants may experience stress or frustration related to diet tracking or meeting weight loss goals.
