Meta AnalysisThe effects of curcumin supplementation on body weight, body mass index and waist circumference: a systematic review and dose-response meta-analysis of randomized controlled trials.
Background & Objectives: Inconsistent data are available about the effect of curcumin supplementation on body weight. This systematic review and meta-analysis was done to summarize data from available clinical trials on the effect of curcumin supplementation on body weight, Body Mass Index (BMI), and Waist Circumference (WC). Methods: PubMed, SCOPUS, Cochrane Library and Google Scholar were searched to find relevant articles up to August 2018. ⋯ Based on subgroup analysis, we found that the effect of curcumin on WC was significant in studies that prescribed ≥1000 mg/d curcumin (P ≤ 0.001), those with the intervention duration of ≥8 weeks (P ≤ 0.001), and those that was performed on overweight subjects (P ≤ 0.001). Conclusions: We found a significant effect of curcumin supplementation on body weight and BMI, but not on WC. However, the effect of curcumin on WC was significant in studies done on overweight subjects, used ≥1000 mg/d curcumin, and ≥8 weeks of duration.
