Abstract

The aim of this study was to assess the effects of a nutrition education program on overweight/obese patients with non-alcoholic fatty liver disease (NAFLD). This single-blind, parallel randomized controlled trial was conducted on 82 NAFLD patients (mean age 48.89 ± 9.85 years) in Isfahan, Iran. Patients were randomly allocated to receive nutrition education program combined with usual care or usual care alone for 2 months. Metabolic markers, including lipid profile, fasting blood glucose (FBG) and dietary intakes were obtained for each patient at baseline and at the end of the study. Nutrition education intervention resulted in a significant decrease compared with usual care in serum levels of total cholesterol (TC) and triglyceride (TG) (p < 0.05). However, our intervention did not lead to a significant improvement in FBG, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C), respectively (p > 0.05). Furthermore, energy and sugar intakes of patients were reduced significantly in response to our intervention (p < 0.05). Nutrition education intervention significantly reduced serum levels of TC and TG but did not affect other metabolic markers including FBG, LDL-C, and HDL-C. Also, it could reduce total energy and sugar intake. Thus, this study could be useful to use this educational program for NAFLD patients in order to influence their metabolic markers and dietary intakes.
