Truth analysis:

Drinking coffee helps to lose weight, but there are corresponding conditions. This condition comes from the principle of losing weight, that is, the energy intake every day is lower than the consumption, and you can lose weight healthily. 1. First of all, in terms of energy intake, coffee is mainly made of roasted coffee beans, and its energy is not high. A cup of 100g black coffee contains only about 2-3 kilocalories, and the daily calorie requirement of a person is mainly related to his own weight and activity level, usually around 1500- 2000 kilocalories. So black coffee is a low-calorie drink suitable for reducing fat. But it should be noted that most people can't accept the original bitter taste of coffee. In order to cater to the taste of the public, many merchants often add a lot of sugar or creamer (non-creamer) to their coffee, and the energy of the blended coffee will increase exponentially. Excessive energy intake exceeds energy consumption, which will lead to energy not being consumed by the body in time, and then converted into fat accumulation in the body, which will not only fail to lose weight but also gain weight. Therefore, when drinking coffee, it is recommended to choose coffee without sugar and cream. 2. From the point of view of consumption, some studies show that caffeine in coffee will increase energy consumption, so before exercise, we can try to drink a cup of coffee to relieve fatigue, improve our spirit and increase the efficiency of exercise time and energy consumption. 3. From a health point of view, long-term intake of coffee in large quantities may cause insomnia, palpitations and other uncomfortable symptoms, especially for patients with stomach diseases. Excessive drinking of coffee may further aggravate the condition. Weight loss mainly depends on exercise, in which coffee only plays an auxiliary role, and long-term drinking is not recommended. In combination, if you want to lose weight with coffee, you should first keep enough exercise, choose coffee without sugar and cream, and occasionally drink a little before exercise.

Expert summary:

Although drinking coffee can help you lose weight, from a medical point of view, drinking too much caffeine can also harm your health, such as irritability, nervousness, insomnia, etc., so drinking coffee to lose weight is not reliable. The correct way to lose weight is to control the daily total calorie intake and increase energy consumption. That is to say, on the one hand, we should control our diet properly to avoid taking in too many calories, on the other hand, we should do more exercise and consume excess calories.
