Luckin's Pomelo C Series is hailed as a fat-burning miracle, but testing shows that although its calories are low, it raises blood sugar fairly quickly, so those trying to lose fat should be cautious.

After the Luckin Yuzu C series returned, it quickly became popular, and many people on social platforms have hailed it as a "fat-flushing miracle," with claims even circulating that "one cup can make you lose two jin." However, actual test data show that although a single cup of the Yuzu C series contains about 105 to 150 calories, blood sugar rises fairly quickly after drinking it, and the blood sugar increase of Yuzu C Iced Tea can reach 5.1 half an hour after a meal. In addition, the formula contains high-fructose corn syrup and white granulated sugar, so so-called 0 fat does not equal low sugar. For people who need to lose fat or control blood sugar, this drink may not only fail to help with weight loss, but may instead promote fat synthesis and increase hunger due to a large secretion of insulin. This article, combining netizen reviews and formula information, restores the true picture of the Luckin Yuzu C series. [more…]
