real hunger comes on slowly and has no urgency to it. it doesnt involve focusing on one particular food. usually it is deep in the stomach and is not what you could call mouth or head hunger. if i've missed something, someone will be along soon with more to add
Yes, it can get a bit urgent though if you leave it long enough
It certainly doesn't have the compulsiveness attached to it...well, not necessarily for the 'beige foods'. I also find that as I get really hungry I can't distract myself. My thoughts just keep returning to having a meal. It's hard to concentrate, even when I'm doing something that I'm enjoying.
I start getting a bit headachey....sometimes a little lightheaded. Just before that, when I'm beginning to feel hungry, I feel good; energetic and very clear headed.
When I eat when hungry, I focus on my food more. I'm less distracted. After a while of eating, I find my thoughts wander and I know that I'm not really hungry anymore and am entering the 'satisfied zone'.
