Frequently Asked Questions (FAQ)
What is the purpose of this study?
Improving your diet can have a significant impact on your health, but it’s not known which diet can best address health needs. Many nutrition studies in the past have not included African American participants. For this study, we are only recruiting African American adults. We hope to learn from you about which diets work best to help prevent chronic disease and improve body weight.
What’s the study about?
The Diet Guidelines: 3 Diets (DG3D) study is comparing three different diets, as defined by the US Dietary Guidelines and how they impact type 2 diabetes risk factors among African American adult (such as body weight, blood pressure, and hemoglobin A1c). The intervention will last for 1 year and participants will be randomly assigned to follow a Nutrient-Rich diet, Plant-powered diet, or Mediterranean diet and receive cooking classes, recipes, and guidance for following their assigned diet based on culturally-tailored curriculum.
What will I get by participating?
Free cooking classes, recipes, a support system, and lab results at the end of the study. If you complete the study, you’ll receive $100.00.
How could participating help me?

Who can participate in this program?
You must:
- Be between the ages of 18 – 70 years
- Self-identify as African American
- Have a body mass index (BMI) between 25–49.9 kg/m2 (be overweight or obese)
- Be available to attend all study meetings over a 1 year period.
- Be willing to be randomized to either of the 3 diet groups (this means you won’t have a choice in which diet you are assigned to)
Is the study only for African Americans?
Yes. You must self-identify as an African American in order to qualify and participate.
How can I calculate my BMI to know if I qualify for the study?
You can calculate your BMI online with this online calculator: https://www.nhlbi.nih.gov/health/educational/lose_wt/BMI/bmicalc.htm
Can my spouse participate as well?
Only one person per household can participate in the study as a research participant, but you are free to share all your class materials with friends and family.
What commitment is required of me?
This study will last for 1 year and will therefore require a short-term commitment. You will be required to regularly attend virtual classes, lab visits, and to complete a variety of surveys. You will be required to attend classes once a week for 6 months and then every other week for the remaining 6 months. The virtual classes are structured to be about an hour and fifteen minutes.
What will I have to do in the program?
You will attend group classes to learn more about your diet and receive the support you need to adopt healthier eating habits. The classes will include cooking skills, recipe ideas, and guidance for following your assigned diet.
You will have lab visits that involve height and weight measurements, blood pressure, and a non-fasting blood draw via finger stick. The lab visits will be at the following time points: baseline and 6 months and 1 year.
You will also be completing several questionnaires at each time point: baseline, 6 months and 1 year. You will complete the questionnaires at your classes or at your house and be required to complete online dietary recalls at home. The questionnaires will assess demographic information, psychosocial variables (such as stress), and dietary acceptance. The dietary recalls are online surveys that ask you to recall all the meals and beverages you had in the previous 24-hours. You will be directed to an online database that allows you to enter in the foods and drinks you had for the day.
Can I pick what diet group I belong in or what diet I get to eat?
No. Because this study is using random assignment, participants will be randomly assigned to each diet group. You must be willing to be assigned to either of the 3 diets.
What happens if I can’t attend a class?
Please let one of our study coordinators know that you will miss a class and you will be provided with instructions to complete a make-up class.
What do I do during lab assessments?
You will have your blood drawn (non-fasting) via a finger stick by a phlebotomist at USC’s Prevention Research Center or your local LabCorp Patient Service Center. You will have your body weight, height, blood pressure, waist circumference, and hip circumference measured.
