The sweetness of substitute sugars such as aspartame, sucralose and acesulfame K in Xi tea raw materials is much higher than that of sucrose, but the calorie is 0. Xylitol, erythritol and other sugar substitutes also have considerable sweetness, which will produce extremely low calories, so it is 0 fat.

This does not mean that people who lose weight can indulge in drinking sugar-free drinks. On the one hand, sugar-free drinks may increase people's demand for other high-calorie sweets. On the other hand, sugar-free drinks are light in taste, giving people a feeling of low calories, which easily leads to an increase in the intake of other foods. Drinking sugar-free drinks with cakes and hot pot is very calorie-intensive. At the same time, sugar-free drinks do not contain sucrose, but there may be many other unhealthy ingredients, and the total calories are not low. In addition, for sugar-free new tea drinks, ingredients such as cream and pearls also contain sugar, which is still heat after digestion and absorption. Therefore, drinks without sucrose are not equal to low calories, and there is still a risk of obesity if you drink too much.
