Where does fat/muscle go after it is lost?

Question

I understand at a very basic level that when we lose weight, our bodies burn fat stores for energy. But since we don’t have a little fire actually going on in our bodies, where does this fat go? How do we ‘excrete’ these pounds and pounds of fat and not ever see where it goes? Same thing with atrophied or “lost” muscle – where does it go?

Answer 1

It’s converted into energy in a similar but far less noisy and violent way your car turns gasoline into energy to move the car and CO2.

The compounds that can’t be burned for energy are either urinated, defeated or exhaled.
