I think a far better question is "have you drunk any water in the last 2 hours" Most of the time I think I'm hungry, I'm actually thirsty. Take now for example, I've just eaten lunch and a coffee, but I'm feeling like I could really do with an apple (I had one for breakfast). I suspect that's because I'm dehydrated rather than hungry. Instead it's the other way round (have you eaten? If yes, drink water)
