I know that sugar really plays havoc with my hunger signals. Before primal i was eating sweet cereal bars, ice cream, mousses etc and i never found one satisfying, i was always reaching out for a second. The hunger was real belly hunger and i used to get sugar crashes - feed-me-now-i've-gone-dizzy etc.
Now that sugar is excluded from my diet those hunger pains and light headedness have gone away. It's like a miracle. I never would have thought it was possible. So i believe if you've got sugar in your diet it messes with your hunger signals. Also, so do 'diet' varieties i've heard, as the body was expecting sugar and got some unknown chemicals, so still wants that sugar you promised. I can have a bit of fruit but i've got to be careful not to have more than two pieces of fruit, and definitely not in place of a meal or i'd be hungry 2 hours later.
I hate doing a mee too but yeah before PB, I was a every 3 hour gotta eater. I was deeply ravenous and quickly became hypoglycemic if I did not eat. I could not pass a Mc dee's I was starving sick to my stomache hungry all the time. and 350+ lbs.
Now no matter how hungry I get the panic is mostly gone and all in my head. No more sick to my tummy OMG I am going topass out.

Interestingly, obese people (BMI >30) actually have HIGHER levels of ghrelin, the hunger hormone, than normal weight people. So they are actually MORE hungry. It's definitely NOT a mental thing, although oral fixation sure plays a role for a lot of people. Why are the ghrelin levels higher? I have no idea, but hopefully in the next decade or two we'll find out - we've only been aware of ghrelin for a decade or so. I recently spoke to a brand-spanking-new gastroenterologist who had never even heard of ghrelin until her fellowship exam - that's how new it is.
Because the stomach has a mind of its own, and is saying FEED ME!!! FEED ME!!!!!!!
The stomach will not take NO for an answer.
Two reasons off the top of my head:
1. You might still have plenty of fuel around your middle, but you ran out of vitamins and minerals.
2. Psychological hunger is a withdrawal symptom of an addiction to dwarf hybrid wheat.
