Turmeric and Reduced Body Mass Index

Research synthesisModerate evidenceModerate effect7 studies · 5 beneficial · 2 neutral · 0 harmful

Across 7 studies, 5 reported beneficial effects of turmeric/curcumin on reducing body mass index (BMI), with a predominantly moderate effect size. The most common dose used was >1000 mg/day, and effects were observed mainly in clinical populations with type 2 diabetes or obesity. The median study duration was 91 days, suggesting consistent use over about 3 months may be needed.

  • Effective dose range: >1000 mg/day
  • Studied populations: adults with type 2 diabetes mellitus, women with severe obesity (BMI ≥ 40 kg/m²) undergoing bariatric surgery, patients with metabolic dysfunction-associated fatty liver disease

Caveats: Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). Some meta-analyses did not find significant effects, particularly in patients with MAFLD, indicating the benefit may not be universal across all populations.
