Does anyone else ever feel this way?

Today I feel like I could eat the house down. I haven't done it, mind you, and I have managed to not eat the wrong things or overeat, I just feel like I could eat the house down! I actually feel HUNGRY and I VERY RARELY actually can say I feel hungry. I have had a hysterectomy so I know if has nothing to do with the "monthly" thing. I was just wondering if it happens to anyone else???
