Abstract

Abstract: In the present study, we explored the effect of curcumin/turmeric supplementation on anthropometric indices of obesity, leptin, and adiponectin. We searched PubMed, Scopus, Web of Science, Cochrane Library, and Google Scholar up to August 2022. Randomized clinical trials (RCTs) investigating the impact of curcumin/turmeric on obesity indices and adipokines were included. We applied the Cochrane quality assessment tool to evaluate the risk of bias. The registration number is CRD42022350946. Sixty eligible RCTs, with a total sample size of 3691 individuals were included for quantitative analysis. We found that supplementation with curcumin/turmeric significantly reduced body weight (WMD: −0.82 kg, 95% CI: −1.30, −0.35; p = 0.001), body mass index (WMD: −0.30 kg/m 2, 95% CI: −0.53, −0.06, p = 0.013), waist circumference (WMD: −1.31 cm, 95% CI: −1.94, −0.69, p < 0.001), body fat percentage (WMD: −0.88%, 95% CI: −1.51, −0.25, p = 0.007), leptin (WMD = −4.46 ng/mL; 95% CI: −6.70, −2.21, p < 0.001), and increased adiponectin (WMD = 2.48 μg/mL; 95% CI: 1.34, 3.62, p < 0.001). Overall, our study shows that supplementation with curcumin/turmeric significantly improves anthropometric indices of obesity and adiposity‐related adipokines (leptin and adiponectin). However, due to high between‐studies heterogeneity, we should interpret the results with caution.
