Because the sugar content of double skin milk is very high, it will not gain weight once in a while, but it will gain weight easily if it is drunk for a long time. Moreover, milk tea contains creamer, which is made of coconut oil. It is particularly easy to gain weight after drinking it, and it will be easier to gain weight if there are pearls in double-skin milk. Pearls are made of cassava, which is a high-sugar and high-calorie food. Therefore, it is conceivable that drinking double-skin milk is not easy to gain weight.
