  "abstract": "Background and aims\n\nEvidence on the effects of ginger supplementation on anthropometric and body composition indices in adults with type 2 diabetes mellitus (T2DM) is inconsistent, and the certainty of this evidence has not been fully evaluated. This study aimed to systematically review and meta-analyze randomized controlled trials assessing these effects.Methods\n\nPubMed, Scopus, and Web of Science were searched until October 5, 2025. We used random-effects meta-analysis to find average differences with 95% CIs. Study quality and evidence certainty were checked with Cochrane RoB-2 tool and GRADE approach. Subgroup, meta-regression, sensitivity, and publication bias analyses were also done.Results\n\nThis meta-analysis included 692 participants from 12 RCTs. Ginger supplementation significantly reduced body mass index (BMI) (- 0.24 kg/m²; 95% CI: -0.48, - 0.00; p = 0.043) and body fat percentage (BF%) (- 1.44%; 95% CI: -2.49, - 0.38; p = 0.007), while no significant effects were observed on body weight (BW), waist circumference (WC), hip circumference (HC), or waist-to-hip ratio (WHR). Bias assessment showed 9 studies with some concerns, 1 low, and 2 high risk. Evidence quality was moderate for 4 outcomes (BMI, WHR, HC, BF%), low for WC, and high for BW.Conclusion\n\nGinger reduced BMI and BF%, with no significant change in BW, WHR, HC, or WC.Trial registration\n\nThis study was prospectively registered in PROSPERO (CRD420251162956).",
