Black coffee is used by A-mei and Nicky Wu to lose weight

Wanting to lose weight but too lazy to exercise, many people will drink a lot of black coffee to help drain water and promote metabolism. It is also widely circulated on the Internet that drinking 1 to 2 cups of black coffee with three meals a day has miraculous effects on weight loss and edema. It is said that Asian Queen A-mei and the eternal Thunderbolt Tiger Wu Qilong have both used black coffee to lose weight. However, relying solely on black coffee to lose weight has always been controversial. The foreign health website fitday lists the pros and cons of coffee for weight loss.

Ah Mei, whose physique has changed recently, is often captured by the media as having a "slim" figure. However, according to media reports, Ah Mei has successfully lost nearly 10 kilograms by relying on black coffee and a non-starch diet. When she performed on stage a few days ago, netizens praised her for having a "pointy chin". In 2005, Wu Qilong, who needed to lose weight quickly for filming a movie, drank 13 cups of black coffee a day and quickly lost 7 kilograms, but he developed symptoms of high fever and severe palpitations, and almost ruined his health.

It can be found that losing weight by drinking black coffee has always been a controversial method. Some studies have shown that it can help with dieting, but some studies believe that it will be harmful to weight loss plans. According to a report from the foreign health website fitday, the positive and negative effects of black coffee depend on how you drink it.

Black coffee helps lose weight

The report pointed out that the caffeine contained in coffee is a stimulant. After taking it, it can make people energetic and can effectively suppress appetite. Drinking a cup of black coffee in the afternoon or after dinner can also reduce the desire for snacks or desserts and allow the body to avoid calorie burden.

In addition, it is generally believed that black coffee can stimulate metabolism and is itself a very good diuretic. However, studies have shown that black coffee is not particularly effective in burning calories in the body. Although it can help excrete water, the amount of coffee consumed is actually about the same as the amount of water excreted, and it does not have much effect on eliminating water from the body.

Black coffee is harmful to weight loss

When you drink too much black coffee, the caffeine may cause you to lose sleep, increase heart palpitations and stress levels, and cause overeating. And when the pressure rises, it will stimulate adrenaline to secrete cortisol (glucocorticoid hormone in the body, which mainly controls the metabolism of carbohydrates, proteins, and lipids, commonly known as stress alcohol). If the amount is too high, it will cause anxiety, obesity, and chronic fatigue. In addition, insomnia may also cause you to eat more midnight snacks, which will invisibly increase your calorie intake.

Sun Yaqi, a nutritionist at the Ren'ai branch of Taipei City United Hospital, added that people who rely on black coffee to lose weight still need to avoid excessive intake. Adults should not consume more than 300 mg of caffeine per day, which is equivalent to two cups of coffee. People who have excessive stomach acid, stomach ulcers, are prone to insomnia, or are pregnant should avoid the stimulation of black coffee.
