>can someone explain to me why fat doesn't get changed into energy, and disappear through heat? Fat is some complex molecule made up of a bunch of carbons, hydrogens, and oxygens. Where do you think these atoms go? The short of it is the fat molecules are turned into other molecules (which gives you energy) with the addition of oxygen, and the byproducts (water and co2) are expelled as a byproduct.
