Patients with obesity (n = 55, mean [standard deviation, SD] age 44.3[9.2] years, 64% women, 87% non-Hispanic Black) were randomized to receive dietary counselling either in a grocery store or a clinic. Change between groups (analysis of covariance) was assessed for outcomes including: dietary quality (Healthy Eating Index – 2005 [0–100 points] ), and nutritional knowledge (0–65-point knowledge scale). Both groups reported improved diet quality at the end of the study. Grocery participants had greater increases in knowledge (mean [SD] change = 5.7 [6.1] points) than clinic participants (mean [SD] change = 3.2 [4.0] points) (P = 0.04). Participants enjoyed the store-based sessions. Grocery store-based visits offer a promising approach for dietary counselling.en-USGrocery storenutrition educationobesityregistered dieticianJournal Article2016-01-0410.1111/cob.12095
