In recent years, weight-loss coffees marketed as effortless slimming aids have proliferated in the market, attracting a large number of consumers hoping to lose weight quickly.

Recently, a so-called "Mixue Bingcheng weight-loss method" has become popular on social platforms. The routine involves drinking grape iced Americano, jasmine green tea, and iced fresh lemonade in sequence within one day, while trying not to eat anything else. Some followers claim they can lose three to four jin the next day. This method is essentially similar to a liquid fast, relying on water loss and a reduction in intestinal contents rather than actual fat loss. Many who tried it reported discomfort such as weak hands and feet, palpitations, headaches, and insomnia, and doctors also warn that using it rashly may trigger hypoglycemia, hair loss, and even abnormal liver and kidney function. Both Mixue Bingcheng stores and customer service said that these three drinks have no weight-loss effect. [more…]

After specialty coffee became popular, the claim that coffee helps with fat loss spread widely, but the real prerequisite for it to be effective is drinking black coffee with no sugar and no milk, along with a sensible diet and moderate exercise. However, many people can neither control their eating nor get themselves to move, so weight-loss coffees swooped in under slogans like "no exercise, no dieting, no injections or pills, one cup a day and you'll lose over ten jin in thirty days." These products often have no ingredient list, no production information, and no Chinese labeling, yet they sell briskly through channels such as WeChat resellers and Xiaohongshu. After drinking them, consumers commonly experience thirst, nausea, palpitations, and other reactions, and some have even tested positive for the banned drug sibutramine. This article reviews related cases and court rulings to remind everyone to be wary of weight-loss coffees of unknown origin and to view the relationship between coffee and fat loss scientifically.

Recently, a Luckin Coffee employee posted before-and-after photos of their physique on social media, taken before and about a month and a half after joining the company, sparking widespread discussion. The person said that due to a shortage of staff at the store, they had to work 13 to 14 hours straight every day and often had no time to eat, losing 38 jin (19 kg) in a short period and more than 45 jin (22.5 kg) in total. This phenomenon left many netizens both envious and curious, and prompted many Luckin employees to share similar experiences: losing a dozen or so jin, developing muscle definition in their arms, and even improving their posture. However, behind this seemingly "paid weight loss" is a continuous flood of orders triggered by low-price promotions on delivery platforms and intense physical labor. This article will trace the origin and development of this topic and explore the potential health risks of this unconventional way of losing weight. [more…]

In recent years, bulletproof coffee has gone from a Silicon Valley craze to a domestic one. Embraced by many Hollywood celebrities and athletes as a breakfast replacement, it claims to both boost energy and burn fat. Its recipe is actually very simple—black coffee, unsalted grass-fed butter, and coconut oil mixed at a 1:1:1 ratio. Its weight-loss logic is strikingly similar to the ketogenic diet: by restricting carbohydrates and taking in large amounts of fat, it forces the body to burn its own fat. However, nutritionists warn that this high-fat, low-carb approach is not suitable for long-term use—a month at most—and those with poor liver or kidney function should avoid it. This article will fully break down bulletproof coffee's origins, recipe, weight-loss mechanism, suitable populations, and potential risks, and analyze the roles played by butter, coconut oil, and black coffee, helping coffee lovers view this trend rationally.

A recent food safety punitive damages case disclosed by the Supreme People's Court has once again made the topic of coffee for weight loss a focal point. In August 2023, Cui purchased coffee weight-loss products for 2,960 yuan via WeChat. After taking them, he experienced symptoms such as thirst and dizziness. An investigation revealed that the manufacturer indicated on the product had long since had its production license revoked, so he filed a lawsuit in court. The Xiushan County People's Court of Chongqing determined that the merchant sold food knowingly not meeting safety standards and ordered the return of the purchase price plus ten times the compensation, totaling 32,560 yuan. At the same time, discussions on social platforms about coffee for weight loss are sharply divided: some share experiences of drinking coffee during fat-loss periods to boost metabolism, while others expose terrifying experiences of palpitations, cold sweats, and even testing positive for sibutramine after consumption.

Bulletproof coffee has been hailed as a weight-loss miracle in recent years, but its essence is nothing more than butter and MCT oil blended into black coffee, mimicking the idea of Tibetan butter tea. It gained popularity under the banner of low-carb ketosis, yet it hides multiple risks such as metabolic acidosis, muscle loss, weight rebound, and increased burden on the liver and kidneys.

In recent years, a "raw coffee" launched by a coffee shop in Nagoya, Japan, has attracted the attention of health scholars and celebrity models. This drink, made by brewing raw coffee beans together with roasted coffee beans, is said to far outperform black coffee in terms of weight loss. A four-week experiment showed that participants who drank raw coffee lost significantly more weight than those who drank black coffee, and the key behind this lies in the abundant chlorogenic acid in raw coffee beans. Chlorogenic acid can improve insulin sensitivity and regulate glucose and lipid metabolism, and has preventive and therapeutic effects on obesity and metabolic syndrome. However, chlorogenic acid is sour and astringent and unpleasant to the taste, and is degraded after roasting. Raw coffee tastes light, with nutty and roasted barley tea flavors, but it still contains caffeine and should not be drunk in excess. This article will provide an in-depth analysis of the weight-loss principles of raw coffee, the mechanism of action of chlorogenic acid, and its essential differences from black coffee. [more…]

Behind the buzz of "Luckin as a weight-loss base," how exactly do you balance the physical exertion of manual labor against the toll it takes on the body? This article walks you through the real experiences and warnings of these food-service workers. [more…]

Actress and director Jia Ling sued a company in Anhui for unauthorized use of her cartoon boxing image on the packaging of its "Ms. Jia Black Coffee" and implying weight-loss benefits. Recently, the Qiaocheng District Court in Bozhou, Anhui, ruled that the defendant infringed Jia Ling's portrait rights and ordered it to stop producing the infringing product, issue a public apology, and pay 100,000 yuan in compensation for economic losses. The case stemmed from the box-office success of the film YOLO, when some merchants promoted black coffee products under the guise of "Jia Ling's same style," while the film's official team repeatedly clarified that it had never authorized any endorsement of fat-reducing products. This article reviews the course of events and the key points of the ruling, while reminding consumers to view celebrity-endorsed coffee marketing rationally. [more…]

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…]
