Simplifying Diet Tracking in a Digital Weight Loss Intervention (NCT07601061)

Simplifying Dietary Self-Monitoring in a Digital Weight Loss Intervention

🟡 Not Yet Recruiting Observational / Diagnostic 🧠 Behavioral & Psychological Program Sponsor: Stanford University

🩺 Plain-English Summary (8th-Grade Level)

The purpose of this study is to compare two approaches for tracking dietary intake in a 12-month fully digital weight loss intervention: (1) Simplified approach: track Red Zone Foods (e.g., foods high in calories and low in nutritional value) vs. (2) Detailed approach: track all foods and their corresponding calories. In essence, this is a head-to-head comparison of two tracking approaches; the investigators are evaluating whether weight loss is comparable over 12 months, or whether one approach will have greater weight loss. The investigators will recruit 328 adults. Broadly, adults with overweight or obesity who live in the United States will be eligible. The weight loss intervention will last 12 months. All participants will be asked to track their dietary intake + body weight + steps daily as well as complete weekly behavioral lessons and action plans to promote healthy eating and physical activity. All study tasks will occur remotely. Assessment of body weight and survey measures will occur at the beginning of the trial ("baseline"), and at 1, 6, 12, and 18 months.

Who can join: To join this study, participants generally need to meet the listed inclusion criteria (9 items) and avoid the listed exclusions (13 items).

Location: Stanford University School of Medicine — Palo Alto, California

Age range: 18 Years
