The weight-reducing and lipid-lowering effects of Pu 'er tea mainly come from two aspects: First, it is formed by the comprehensive action of tea polyphenols, chlorophyll, vitamin C and other effective components (the tea polyphenols content of big tea trees in Yunnan tea-producing areas all reached 30-34%, the total catechin content reached 18-24%, and the foam resistance and tea extract reached 46-50%). The second is the comprehensive effect of various beneficial bacteria formed in the fermentation process (the effect of bacteria can reduce the absorption of triglycerides and sugars in the small intestine and improve the decomposition of waist and abdomen fat by enzymes).

Therefore, the weight loss effect of Pu 'er tea is better than that of black coffee.
