Beneficial effects of catechin-rich green tea and inulin on the body composition of overweight adults.

Green tea catechin has been proposed to have an anti-obesity effect. The aim of the present study was to investigate whether the effect of catechin-rich green tea in combination with inulin affects body weight and fat mass in obese and overweight adults. A total of thirty subjects were divided into a control group and an experimental group who received 650 ml tea or catechin-rich green tea plus inulin. A reduction of body weight ( - 1·29 (sem 0·35) kg) and fat mass (0·82 (sem 0·27) kg) in the experimental group was found after 6 weeks, and no adverse effects were observed. After refraining from consumption for 2 weeks, sustained effects on body weight and fat mass were observed. We conclude that continuous intake of catechin-rich green tea in combination with inulin for at least 3 weeks may be beneficial for weight management.
