Hello, I'm a salesman of coffee powder. Through my years of experience, coffee powder itself has the effect of burning fat and relaxing bowels. The key is to see whether the coffee you choose is pure coffee, because many domestic instant coffees also have the function of burning fat and relaxing bowels, and adding plant fat powder, cream and other substances makes people fat, which not only has no effect, but will increase weight and aggravate constipation. If you are not used to the bitter taste of ordinary coffee, choose instant coffee, which does not contain vegetable fat powder and creamer.
