Objective To evaluate the curative effect of the low-fat diet (LFD) and low-carbohydrate diet (LCD) on non-alcoholic fatty liver disease (NAFLD). Methods Databases including PubMed, Embase, Medline, Cochrane library, Web of Science, China National Knowledge Infrastructure and Wanfang Data were searched from inception to January 2019 for the randomized controlled trials on LFD or LCD in NAFLD therapy. Patients in studies included were divided into the very low-carbohydrate diet (VLCD) group, the LCD group, the medium-carbohydrate diet (MCD) group and the high-carbohydrate diet (HCD) group. And Stata11.0 was used to process the data. Results A total of 11 studies were included, comprising 420 NAFLD patients. There was no statistical difference in the body weight loss, total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyltranspeptidase (GGT) and intrahepatic fat in patients with NAFLD between VLCD and LCD groups (P>0.05). Compared with the LFD group, the MCD group had lower TG in NAFLD patients (mean difference [MD] =-32.141, 95% confidence interval [CI] -58.280 ~ -6.001, P=0.016), while there were no significant differences in the body weight loss, TC, HDL, LDL, ALT, AST, GGT and intrahepatic fat (P>0.05). The HCD group had lower TC in patients with NAFLD (MD=-0.59, 95%CI -0.979 ~ -0.201, P=0.003), while there were no statistical differences in the body weight loss, TG, HDL, LDL, ALT, AST, GGT and intrahepatic fat (P>0.05). Conclusion There is still a lack of evidence for the superiority of LCD or LFD in the treatment of NAFLD. More evidence-based studies should be conducted to evaluate the long-term effects and stability of LCD.
