We aimed to evaluate the effect of Cuminum Cyminum (CC) supplementation on lipid profile and selected anthropometric parameters. PubMed, Scopus, Web of Science, and Embase databases were systematically searched until May 2021. The random-effect model was used to study the effect sizes. The sources of heterogeneity were assessed using subgroup analysis and meta-regression. Publication bias was studied by funnel plots. The GRADE approach was used to assess the overall quality of the evidence.The data from our eight included studies have indicated that CC supplementation can lower body mass index (BMI) (WMD = -0.88 kg/m2 ; 95%CI: -1.58, -0.18; p = .023) and total cholesterol (TC) (WMD = -3.96 mg/dl; 95%CI: -6.51, -1.04; p=.008). Also, after adjusting for publication bias, CC was shown to be effective in improving waist circumference (WC), high-density lipoprotein (HDL-C), and triglycerides (TG) levels. Although, the current evidence has not shown that CC supplementation can affect low-density lipoprotein (LDL-C), our subgroup analysis has indicated that CC supplementation with supplementation length of more than 8 weeks is associated with beneficial effects on LDL-C.While CC might be a suitable choice in managing BMI and TC, further high-quality studies are needed to confirm its efficacy in the clinical setting.
