You learn something new every day, and today, I learned that when you burn fat, you actually lose most of it (80%) by breathing it out in the form of carbon dioxide. The rest goes out of your body in liquid form, through your pee, sweat, and other bodily fluids.

So for every 10 kilograms of fat you burn, you have to inhale 29 KG of oxygen to break down the fat and release its energy, which produces 28 KG of carbon dioxide and 11 KG of water. Fascinating, isn’t it?
