Yes, I think it's possible. It's something you can't label an "addiction" as easily as you can smoking or drinking because you need some kind of food to survive, but when I was a huge porker, fast food was something I would legitimately crave if I went a certain amount of time without it. If someone wants to troll me about the following I really don't give a because I lost the weight , but I had days where I had fast food 3 times, all of them being when I'd order a good amount.
