What is, or rather comprises, fat person smell?

It is excess body giving off fumes as it tries to deal with the excess body. It is not being able to clean as well. It is inefficient metabolism so things are not processed properly. If you have ever been tired lacking good sleep for days your body falls apart and things happen inside and out. Food is treated like an invading foreign substance and the body attempts to flush it out. Poopoo is not properly digested. Things come out of your pores. Your skin and hair gets greasy. You have to blow your nose and your eyes water. Get the picture?
