Elves/dark elves are nice because they're naturally so lithe and fair, so it's hot to see them lose their grace to hundreds of pounds of adipose. In my opinion, it's hottest when they're royals or some other powerful position then brought down into slavery and fattened up like livestock, especially if they resist. One of my favorite WG short stories goes along those lines.
Another fantasy race that isn't quite aligned with this thread are orcs. For me, it's kind of just the opposite end of the spectrum where orcs are usually large, muscular, and powerful whereas elves are slim and limber. Along the same lines as elves, I like it when proud, hardened, competent warrior orc women are defeated and captured or something like that then fattened up as trophies on display, losing all their martial prowess to piles of useless lard. They're usually aggressive, and hard to break, so that's a plus for me as well.
Power dynamics are a big thing with me as you can tell.
