This is where your fat actually goes when you burn it off

Have you ever wondered where all that fat goes you've lost after all that rowing at the gym?

No, you don't sweat it out. That's a common misconception. Fat isn't lost as energy or heat either.

Even some doctors and nutritionists have been known to get this wrong, according to science channel SciShow. They puzzle over the chemistry, and the "concentration of mass" that appears to simply vanish without being in the heat generated, or energy created during exercise.

But fat doesn't just... disappear. All that extra padding has to go somewhere. We're not talking about restricting calories and dieting here, by the way.

The simple fact is this: you exhale it. You breathe fat out.

Biologists at the University of New South Wales in Australia recently conducted an "atom-by-atom" breakdown of where the mass of your fat goes after it's burned from your body.

The researchers found a simple formula: for every ten kilograms of fat you burn, you've got to inhale 29 kilograms of oxygen. This reaction causes the body to release 29 kilograms of carbon dioxide and 11 kilograms of water.
