There are only two thinsg that leave the body urine/sweat (the two are very similar) and CO2.

Assuming we are talking aboy loss of fat (and there are other ways to lose weight too - like loss of muscle, or just reduced water retention), then the fact will primarily (but I suspect not exclusively) have been converted to water and CO2.

That was what I meant, although I am also aware that I am glibly ignoring bile, which is excreted into the the intestines, and ofcourse so too is water, but the rest is simply food that never entered or left the bloodstream.

Saliva, gastric and pancreatic juices plus bile make up 3-4 liters,
then most of the liquid is reabsorbed, in normal conditions, of course.
