Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects are recruited through hepatology outpatient clinics and hospital and university intranet. Subject are screened by the hepatologist and consented by the PI. The hospital clinical trials pharmacy coordinator randomises the subjects by computerised sequence generation as they have given written consent to participate in the study. All investigators are blinded to the randomisation

Summary
Brief summary
The study aims to investigate the role of a bioactive food compound called resveratrol, found in grapes, peanuts, berries and derived food products and beverages, in the treatment of obesity related fatty liver disease. Studies in animal models of fatty liver disease have shown promising results with resveratrol treatment: improvement of insulin sensitivity, prevention of fat accumulation in the liver, reduction of inflammation and increased antioxidant activity.
