The aim of the study was to investigate the anti-obesity effects of the Fuzhuan brick tea and green tea on a high-fat-diet induced rat model. Experimental groups were given daily oral administrations of tea aqueous extracts at different concentrations, which yields doses of 75mg/kg, 150mg/kg or 300mg/kg. The results showed that the body weight gains and the weights of perinephric fat pads and epididymal adipose tissues were significantly reduced in rats administrated with tea aqueous extracts compared with the model control group. Supplementation with tea aqueous extract decreased the values of the food utilization efficiency, fat coefficient and Lee’s index. Histological analysis in the present study showed that both tea aqueous extracts had suppressive effects on the number and size of the adipose tissue fat cells. Moreover, serum levels of the triglycerides of the Fuzhuan brick tea groups are lower than that of the green tea groups.
