Black coffee is high in caffeine, no more than four cups a day to avoid palpitations, trembling fingers and other uncomfortable symptoms.

The black coffee diet has been constantly reposted on the Internet, pointing out that drinking a cup of black coffee before breakfast can increase metabolism by 5%, reduce appetite throughout the day, and reduce calorie intake by up to 25%. Let many netizens who see the article for the first time flock to it, but the real situation is quite different from the effect claimed in the text.

After the coffee diet spread on the Internet, manufacturers also launched slimming coffee. According to coffee data, black caffeine contains a lot of caffeine, which stimulates the central nervous system and makes the heart beat faster, resulting in a higher metabolic rate and indirect fat burning. In the past, there was an artist Wu Qilong who lost weight with black coffee and drank 13 cups a day at most. Although he achieved the effect of losing weight, he almost lost his life.

Dietitian at Cathay Pacific Hospital pointed out that caffeine can stimulate the human body and achieve sweating and other effects. The pharmacological effects of caffeine can indeed lead to weight loss, but to achieve significant results, there must be a large amount of caffeine stimulation. The side effects of excessive caffeine can be fatal, including insomnia, anxiety disorders, severe gastric ulcers, and even palpitations, seriously affecting cardiopulmonary function. Therefore, it is only suitable to drink up to 3 to 4 cups a day. According to the recommendation of the Department of Health, adults should not consume more than 300 milligrams of caffeine a day.

In other words, if people who have a slow metabolism or do not often exercise and sweat regularly drink the right amount of black coffee, as long as they can adapt to side effects such as insomnia, they can indeed achieve some weight loss and promote metabolic defecation; but on the other hand, if you already have gastrointestinal problems, or cardiovascular or heart disease patients, drinking black coffee every day will cause a burden on the body, or even worsen the original condition, this method is not applicable to lose weight.

According to a research report published in the American Journal, the first best weight loss drink is plain boiled water, followed by sugar-free tea, followed by black coffee. Fat boys and girls who want to lose weight, unless they are sure that they are in good health, do not have any insomnia or heart problems, or obediently drink boiled water, with diet and exercise is the right way to lose weight.
