Question

Right now, I'm reeeeally hungry, feeling shaky because of my lowblood sugar and all. I'm wondering though why my stupid bodydoesn't realise that there are plenty of nutrients around my waistso I would neither have to feel bad nor to run for a cheesesandwich. I've heard that burning fat is a slow process but fromexperience I can tell that this feeling only gets worse. So I'd beglad if you could answer this question in one of your upcomingshows: why do I feel so abhorrently hungry when there's enough todigest without actually involving my digestive tract?
