The primary way we get rid of excess weight is actually breathing. As we breath out, CO2 is produced. So when we burn more calories than we take in, your body gets rid of the excess carbon in the form of exhaling. Of course other methods of “elimination” in the rest room count too, but the main source of permanent weight loss is still breathing
