Catechin in Lipton Liya tea is a kind of flavonoid polyphenol, which can circulate through the blood to the whole body, enhance the oxidation of fat and energy consumption, thus achieving the effect of inhibiting obesity. It is worth mentioning that catechins not only act on subcutaneous fat, but also on the fat around internal organs. White-collar elites in sedentary offices are prone to accumulate fat in their bellies due to lack of exercise on weekdays. So for busy women, catechins will have a better slimming effect. Since March 2009, Lipton Liya tea has been sold in Watsons all over the country. Drinking oolong tea or Pu 'er tea contains 20 to 70 mg of catechin per 200ml cup, which varies slightly depending on the place of origin and brewing method. However, the study found that only 880 mg of catechin per day can reduce weight, which is equivalent to the catechin content in two cups of Liya tea per day. Drinking 40 cups of oolong tea or Pu 'er tea every day can be equivalent to the weight loss effect of two cups of Liya tea ~ ~
