First, Xuanyi may drink 8 cups of milk tea a day, just a few mouthfuls. We all know that female stars now strictly control their diet in order to look better in front of the camera. As for the calories of milk tea, they generally don't touch it. So Xuan Yi, after drinking so many cups of milk tea, can still maintain such a perfect figure, probably because he only drank a few mouthfuls of milk tea. Because for him, drinking milk tea doesn't have to be finished, he just wants to taste the taste of each different milk tea. Therefore, it is relatively easy to exercise without drinking too much milk tea.
Second, Xuanyi will definitely choose fitness after drinking milk tea. Because milk tea is a very high-calorie food, he may stay in the gym for several hours after drinking milk tea. As long as they eat food with calories, they will spend more effort to consume this calorie. So now many stars, who eat something with calories, will choose to train themselves constantly, thus consuming calories. This is the price paid for good food. When Xuanyi finished drinking milk tea, maybe his daily food was vegetarian food such as vegetable salad.
As for Jay Chou, he will be fat because he doesn't pay so much attention to his figure as a star now. So he won't go on an unrestrained diet like a star. As a female star who loves beans, Xuanyi must pay great attention to her image.
