Context:
Obesity is a prevalent comorbidity in type 2 diabetes mellitus (T2DM) and contributes significantly to poor glycemic control and insulin resistance. Curcumin, a bioactive compound in turmeric, has shown potential in influencing body composition due to its anti-inflammatory and metabolic properties.
Objective:
We sought to evaluate the effects of curcumin supplementation on body weight (BW), body mass index (BMI), and waist circumference (WC) in adults with T2DM.
Data Sources:
A systematic literature search was performed in the PubMed, Scopus, Web of Science, and ISI databases up to January 2024. Reference lists of relevant articles and reviews were also screened manually.
Data Extraction:
Two independent reviewers (N.A. and S.A.) selected randomized controlled trials (RCTs) based on predefined inclusion criteria and extracted data on BW, BMI, and WC changes. The Cochrane risk-of-bias tool was used for quality assessment.
Data Analysis:
Nine RCTs involving 699 participants were included. Pooled estimates were calculated using a random-effects model. Curcumin supplementation significantly reduced BW (weighted mean difference [WMD], -1.65 kg), BMI (WMD, -0.69 kg/m2), and WC (WMD, -0.93 cm). Subgroup analyses indicated greater reductions at doses >1000 mg/d.
Conclusions:
Curcumin supplementation may beneficially affect body composition parameters in T2DM patients, particularly at higher doses. Further high-quality RCTs are warranted to confirm long-term benefits and clinical significance.

This review was not registered in PROSPERO.
