There is a simple reason. First of all, the main component of coffee is caffeine. The biggest function of caffeine is to stimulate nerve excitement, thus promoting blood circulation, diuresis and refreshing. Whether he can lose weight does have a certain auxiliary effect, but he must cooperate with the corresponding exercise.
In other words, black coffee can be used as an auxiliary weight loss drink, but it depends entirely on black coffee. Only when you have a certain amount of exercise, drinking black coffee is useful. Therefore, it is impossible to draw a perfect equal sign between drinking black coffee in the morning and losing weight. Finally, let your body move, plus the role of coffee, which can better help you burn fat and lose weight.
The premise here is that you must exercise. Without exercise, you can't lose weight just by drinking coffee and how much coffee you drink.
Secondly, losing weight by black coffee is an unhealthy way. If you choose to use it as an auxiliary means of exercise to lose weight, it is ok, but it should not be excessive, and it should be carried out in line with the real reason of your obesity.
For example, for those who have slow metabolism, don't sweat at ordinary times and have constipation problems, it is very good for these people to lose weight with black coffee. Can improve metabolism, but also improve the effect of weight loss, because the role of caffeine is to excite the sympathetic nerves of the internal organs.
But people with insomnia or heart problems are not suitable for drinking black coffee.
