Black coffee itself can lose weight, regardless of the kind of coffee beans. This kind of advertisement is misleading to consumers, and there is no such statement.

The principle of black coffee to lose weight is diuresis, accelerating detoxification and accelerating fat burning. So make a cup of black coffee by hand every morning, remember not to add sugar or milk, and then do high-intensity exercise half an hour later, which will burn fat more effectively than usual. But because coffee is not suitable for everyone's physique, and even some people will have diarrhea when drinking coffee, the black coffee diet is not suitable for everyone.
