What this trial studies
This trial aims to compare two different formats for delivering a 12-month behavioral weight loss program: an automated online program and a group-based videoconference program. Participants will be randomized into one of four groups, receiving either coaching or no coaching alongside their chosen format. The study will assess weight loss outcomes and participant engagement at multiple time points, including baseline, 6 months, 12 months, and 18 months post-treatment. Additionally, the research seeks to identify which intervention combinations are most effective for different individuals, potentially leading to tailored recommendations for future weight loss programs.
Why it matters
Potential benefit: If successful, this study could provide effective weight loss strategies that are accessible and tailored to individual needs.
How similar studies have gone: Other studies have shown promise in using remote interventions for weight loss, indicating that this approach is both relevant and potentially effective.
