NCT ID NCT03266666
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Researchers evaluate a program that pairs six lifestyle change classes with grocery credits to encourage healthier eating, physical activity, and stress management. Participants are Lake County, California residents who attend the classes and answer questionnaires about their habits at the start, 45 days, and 90 days. As they attend and complete surveys, they unlock credits for an online grocery store, fresh produce from a local farmers market, and local fitness classes. The study tracks whether these incentives shift diet, exercise, and shopping choices.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lifestyle change classes plus grocery credits
- What this could lead to
- If the approach works, communities could use classes paired with grocery credits to help people build healthier eating, exercise, and stress habits.
- What could go wrong
- This is a small, early evaluation with no control group, so any improvements may come from other factors. Results may not apply outside Lake County.
