Lunchtime hunger

Just something I'm pondering about.

Had a really busy morning, it's not 1.30 and I'm really hungry.  (doesn't help that I never eat breakfast, but that's another post for another day!)

I read somewhere that if you feel thirsty, you're dehydrated already.  Does the same work for hunger?  Is feeling hungry a good thing or a bad thing?  As in, should I eat little and often to never be hungry, or is feeling hungry a good thing.  Does the stomach churning feeling of being really hungry make you eat more to try and satisfy it?

Hmmm.. that's a bit of a brain fart.  Think I'll head out to get a sandwich now.
