The aims of this study were to evaluate the anti-obese effects of pine needle, black tea and green tea in rats and overweight people. Supplementation of 1, 2, 4 and 8% amount to the control diet of pine needle extract and mixture groups significantly decreased body weight gain and visceral fat mass compared with that of control diet group. Supplementation of 1, 2 and 4% amount to the control diet of black and green tea extracts groups significantly decreased body weight gain and visceral fat mass compared with that of control diet group. Anti-obese effect in body weight gain and visceral fat mass of mixture group was higher than in other groups. In human study, extracts mixture supplementation to overweight subjects significantly decreased both body weight and body fat compared with placebo control group. In vitro study, black and green tea extracts significantly inhibited both the pancreatic lipase and α-amylase activities dose dependently. In conclusion, the anti-obese effects of pine needle, black, and green teas in rats were found. In overweight human subjects, extracts mixture decreased body weight and body fat compared with placebo control group. Anti-obese effect in black and green tea groups might be from an decrease in carbohydrate and fat digestions via inhibition of pancreatic α-amylase and lipase activities in part.
