Where Does The Fat Go When You lose Weight?

When you burn fat, where does the material, the actual wobbly, cushioning and insulating stuff go? The answer to this question might surprise you!

We talk a lot about dieting and burning off fat, but we actually have a lot of misconceptions about weight loss.

Some people think fat is converted into energy or heat, apparently a violation of the law of conservation of mass, while others think you can convert fat into muscle or lose it as heat. All common misconceptions.

It looks like there is surprising ignorance and confusion about the metabolic process of weight loss. What is more surprising is that most of the mass is breathed out as carbon dioxide. It literally goes into thin air.

The good folk at SciShow have put a concise video explaining exactly what happens and where that fat goes.

Watch: When you burn fat, where does it go?


Now that you know next time you go for a jog or a walk, remember that you are emanating fat through your breath and your skin.

Interestingly, this also means that the lungs are the primary excretory organ for fat
