An affordable and simple way to lose weight is to drink apple vinegar! This is a very effective method that has been scientifically verified! This thing is sold in the supermarket, and it is not expensive! But it must be diluted with water before drinking, otherwise it will be bad for the stomach! There is also a stomach disease that cannot be drunk! Attention! This method was taught by our chemistry teacher. Many students in our class have tried it and it is quite effective!
