| Summary: | Previous studies, involving males and females, evaluated the effectiveness of green tea (GT) products in obesity. However, the evidence for its health benefits was lacking when considering females, only. The objective is to examine its effectiveness in the following indicators of obesity: body mass index (BMI), body weight, waist circumference, waist-to-hip ratio, and % body fat upon the intervention of GT products in nondiabetic overweight and obese females. For review and analysis, multiple databases were searched and a total of six studies was found. The results revealed that the treatment group who received GT products underwent statistically significant reductions in BMI, body weight, waist circumference and % body fat. The placebo group experienced decreases in BMI and body weight. Analyses of the differences in post-treatment changes between the groups indicated that, in all five indicators of obesity, there was no significant difference (p > 0.05, all).
