Clinical Trials for Diet, Physical Activity, and Weight Management

The NIDDK conducts and supports clinical trials in many diseases and conditions, as well as healthy lifestyle-related behaviors, including diet, physical activity, and weight management, among different populations. The trials look to find new ways to prevent, detect, or treat disease and improve quality of life.
