Drinking pure coffee (coffee brewed from freshly ground coffee beans) for a long time has a certain weight loss effect because it can promote metabolism (especially diuresis).
But I haven't heard of the idea of drinking coke to lose weight, let alone drinking it together. Coke also contains sugar and won't lose weight.
Be careful not to drink instant coffee. Instant coffee generally contains a large proportion of sugar, which will be counterproductive after drinking.
People can get enough sugar from the food they eat every day, so if they eat too much extra sugar, it will increase the burden on the body and eventually cause side effects (obesity \ diabetes, etc.). ).
