Why am I so dang hungry?

We went primitive camping for 3 days, Wed, Thurs, came back on Friday. Got plenty to eat but ever since I’ve been home I have been really, really hungry and I don’t know why….it’s like I’m missing some ingredient, maybe some vitamin, but I have no idea what it could be. I really had a craving for KFC coleslaw, but we don’t have a KFC around here any more.
