Aims: The objective of this systematic review and meta-analysis is to assess the efficacy of Low Carbohydrate Diet (LCD) compared with a normal or high carbohydrate diet in patients with type 2 diabetes. Methods: We searched MEDLINE, EMBASE, and Cochrane Library database for randomized controlled trials. Researches which reported the change in weight loss, blood glucose, and blood lipid levels were included. Results: A total of 9 studies with 734 patients with diabetes were included. Pooled results suggested that LCD had a significantly effect on HbA1c level (WMD: -0.44; 95% CI: -0.61, -0.26; P = 0.00). For cardiovascular risk factors, the LCD intervention significantly reduced triglycerides concentration (WMD: -0.33; 95% CI: -0.45, -0.21; P = 0.00) and increased HDL cholesterol concentration (WMD: 0.07; 95% CI: 0.03, 0.11; P = 0.00). But the LCD was not associated with decreased level of total cholesterol and LDL cholesterol. Subgroup analyses indicated that short term intervention of LCD was effective for weight loss (WMD: -1.18; 95% CI: -2.32, -0.04; P = 0.04). Conclusions: The results suggested a beneficial effect of LCDintervention on glucose control in patients with type 2 diabetes. The LCD intervention also had a positive effect on triglycerides and HDL cholesterol concentrations, but without significant effect on long term weight loss.
