This is what actually happens to your fat when you lose weight

All it takes is a bit of healthy eating with some regular exercise, and our body fat just melts away like butter.

But where does all our fat actually go?

It's safe to say, the answer will surprise you..

"The correct answer is that most of the mass is breathed out as carbon dioxide. It goes into thin air," physicist Ruben Meerman, MD told POPSUGAR.

Yep, you read that right.

Apparently, 80 percent of the fat we burn is exhaled from our body by our lungs.

The other 20 percent?

That leaves your body via your urine, faeces, sweat and tears.

So, are you now thinking about adding some breathing exercises to your next work out? Think again.

Unfortunately, fat has to go through a metabolic process before we breath it out.
