Well, I don't actually like any of the things in OP's images (I think; I'm not sure what was in the image for fatty: was it some sort of meat? If so, I'm a vegetarian, meaning that it would still be a no). That said, I'd have to go for sweet. I have no willpower when it comes to resisting ice cream (and the ice cream I eat is really fatty too... like Ben & Jerry's and similarly concentrated brands). I also really like cookies. Out of respect for my pancreas, I try to only eat sweets one day a week, but I don't always make it a whole seven days between my ice cream or cookie binges.
