What You Need to Know Before You Apply
What is the purpose of this trial?
This trial will test different diets to see which one best helps people manage their weight and improve heart and metabolic health. Participants will follow various diets, and researchers will compare the results.
Will I have to stop taking my current medications?
Yes, you will need to stop taking any medications for elevated lipids, elevated glucose, high blood pressure, weight loss, or conditions that require corticosteroids to participate in this study.
Is the DGA Mediterranean diet pattern safe for humans?
How does the DGA Mediterranean diet pattern treatment for obesity differ from other treatments?
The DGA Mediterranean diet pattern is unique because it emphasizes whole foods like fruits, vegetables, whole grains, and healthy fats, which align with the Dietary Guidelines for Americans. This approach contrasts with typical Western diets that are often high in processed foods and unhealthy fats, making it a novel strategy for addressing obesity.12345
