Participant Flow

Participants were enrolled into the Ignite study during a 7-week period between December 5, 2023 and January 23, 2024. The trial was fully remote, with recruitment of adults across the United States.

After informed consent was provided, participants were asked to complete a baseline survey, sync their e-scale and activity tracker with the Fitbit app, and submit their baseline weight. Once those tasks were completed, participants were randomized into 1 of 16 conditions.
