Does the Pomelo C Americano Coffee Really Burn Fat?

Lab testing of Luckin's Pomelo C series shows a single cup carries roughly 105 to 150 calories, so it is not calorie-free. The iced tea version raised blood sugar by about 5.1 units half an hour after a meal. The formulas contain high-fructose corn syrup and white granulated sugar, so the advertised 0 fat does not mean low sugar.

For anyone watching fat loss or blood sugar, the drink may work against them. A fast glucose rise triggers a large insulin release, which can promote fat storage and increase hunger rather than curb it. Social posts claiming one cup drops two pounds are personal anecdotes, not measured outcomes, and the pomelo juice itself is simply a low-calorie fruit.

After Luckin's Grapefruit C series returned, it quickly became popular, and many people on social media hailed it as a "fat-flushing miracle," with claims even circulating that "one cup helps you lose two pounds." However, actual test data shows that although a single cup of the Grapefruit C series has about 105 to 150 calories, blood sugar rises quickly after drinking it. The blood sugar increase of Grapefruit 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 combines netizen reviews and formula information to restore the true picture of Luckin's Grapefruit C series.

At the beginning of last month, one of Luckin users' beloved favorites, Grapefruit C Americano, returned, and alongside it came the caffeine-free Grapefruit C Iced Tea. This series of drinks quickly became a recent favorite among consumers, and shares and check-ins from netizens could often be seen on social platforms.

Some consumers found after drinking it that Luckin's Grapefruit C series this time seemed to promote intestinal peristalsis, and some even posted that "one cup of Luckin Grapefruit C helps you lose two pounds," using their personal experience to prove that the Grapefruit C series has a remarkable fat-flushing effect.

It is understood that grapefruit is a low-calorie fruit and is one of the "fat-flushing fruits" recommended by weight-loss enthusiasts. According to Luckin's official promotion, this Grapefruit C series uses 0-fat real fruit juice, and when paired with espresso or jasmine tea, it becomes a low-fat drink.

The successful weight-loss cases of people who tried it can easily excite netizens desperate to lose weight, making them wish they could drink a cup of Grapefruit C every day and become as slim as a flash of lightning within a month. Therefore, many people bought Luckin's Grapefruit C series for the title of "fat-flushing miracle," following the trend to try whether this drink really has a miraculous weight-loss effect.

As for the results of trying it, it can only be said that effects vary due to individual physical differences, and not every consumer can achieve weight loss and fat reduction through it. However, after netizens' reviews, it was found that Luckin's Grapefruit C series not only lacks the rumored fat-flushing effect of "one cup helps you lose two pounds," but is also not very friendly to people trying to lose weight.

According to tests, under normal circumstances, a single cup of the Grapefruit C series has about 150 calories. If you choose not to add extra sugar, the calories are lower, around 105 calories. But after drinking it, netizens found that their blood sugar rose very quickly in a short time. For Grapefruit C Iced Tea, the blood sugar value rose from 5.2 to 10.3 half an hour after the meal, an increase of 5.1, while Grapefruit C Americano had a lower increase of 2.7 half an hour after the meal.

For people who need to lose fat or control sugar intake, blood sugar rising too high or too fast is not a good thing. A rapid rise in blood sugar triggers a large secretion of insulin, and besides suppressing the rise in blood sugar, insulin can also promote fat synthesis and increase hunger, making people want to eat more. Therefore, secreting too much insulin is not conducive to fat loss.

Although blood sugar tests vary from person to person, and different body types will produce different results, most test results show that Luckin's Grapefruit C series is a low-calorie but fast blood-sugar-raising drink. In addition, high-fructose corn syrup and white granulated sugar appear in the grapefruit concentrate formula sheet posted by Luckin employees. From this point of view, Luckin's 0-fat Grapefruit C actually has a not-low sugar content. Long-term consumption may not only have no fat-loss effect for people trying to lose weight, but may also produce the opposite effect due to excessive sugar intake.

As for the weight-loss effects mentioned by customers who tried it, such as "going to the bathroom soon after drinking Luckin Grapefruit C" and "losing one pound the next day after one cup," perhaps it is thanks to Luckin's ice cubes. After all, drinking too many iced drinks may cause diarrhea.
