Randomized Controlled Trial

Low risk

18-65 years of age; BMI between 25- 49.9 kg/m2; self-identify as African American; live in the Columbia, SC area; be able to attend all monitoring visits; be willing to be randomized to either condition and be re-randomized if non-responsive; be free of major health or psychiatric diseases, drug or alcohol dependency, thyroid conditions, diabetes, or pregnancy.

Should not be pregnant (or have been pregnant in the last 6 months), anticipating becoming pregnant in the next 24 months, or currently breastfeeding; should be free of an eating disorder as screened by the Eating disorder Screen for Primary care [ESP]; no current participation in a weight loss program or taking weight loss medications (although participants may be trying to lose weight on their own); no recent or planned bariatric surgery; no recent weight loss (>10 lbs in the last 6 months).

The objective of this study was to test the 3 dietary patterns,as presented by the USDG, among AA adults at risk of T2DM. In this 12-wk intervention, we hypothesized that participants assigned to the Mediterranean and Vegetarian patterns (both diets have an emphasis on plant-based foods) would have greaterimprovements in body weight, HbA1c, blood pressure (BP), anddietary quality (HEI score) than participants assigned to thehealthy US-style dietary pattern.
