Introduction: Green tea consumption has been reported to be associated with weight loss although the results of the studies are inconclusive and potential underlying mechanism is not yet clear. We aimed to evaluate the effect of green tea extract on weight loss, body composition and resting energy expenditure in obesity.
Methods: Twenty-nine obese patients (body mass index (BMI) >30 kg/m2) were included in the study. Weight, BMI, waist circumference (WC), body composition and resting energy expenditure (REE) were recorded at baseline. Patients were randomly assigned to receive green tea extract (400 mg standardized green tea extract, 200 mg polyphenols and 100 mg green tela leaf powder) or placebo along with a standard hypocaloric diet. All measurements were repeated after 3 months.
Results: Fourteen patients received green tea exctract and 15 received placebo. Two groups were similar regarding all parameters. Both groups have lost weight significantly with a decrease in BMI, fat mass and WC. REE did not change in both groups. Addition of green tea extract did no increase REE, amount of weight loss or body composition.
Conclusions: Green tea extract does not have any effect on REE, weight loss or body composition in obese patients.
