when you lose weight what happens to it? Does your body just break it down and "pass" it? Throughy our sweat? Never really thought about it but am wondering.

However, keep in mind that the body stores unused protein as fat. Once that happens, it takes 9 calories per gram to "burn" it versus the 4 calorie per gram it takes to "burn" protein (and carbs, too.)
Furthermore, your fat cells have the ability to expand to 10 times their normal size. Your body can generate an unlimited number of fat cells, too, which won't go away without surgery liek liposuction.
When you burn fat, the atoms that make up that fat don't disapper, as in a nuclear reaction.
They are oxidized, which is a CHEMICAL reaction. I imagine fats are made mostly of carbon and hydrogen. In that case, the carbon as you burn it will mostly exit in your breath as C02. When the hydrogen is oxidized, it would be come water, which is removed from the blood via the kidneys. Any other elements probably wind up as poo, but I'm not a biologist, so I'm not sure about that (Is there any organ- like maybe the liver, that removes solids from the blood in a similar manner that the kidneys remove liquids?)
Here's a picture of a saturated and an unsaturated fat molecule. Note the double carbon bond in the unsaturated fat; there's room for two more hydrogen molecules. That's why it is UNsaturated. If you have more than one double carbon bond, it's poly-unsaturated fat.
