Trying to write on an empty stomach

Is my stomach even really empty? Does anybody even really care? The answer to both questions is probably no.

I find myself after writing a few hundred words to my new blockbuster action-packed epic (almost certainly never going to get finished anyway), having sharp hunger pains. Suddenly a migration to the fridge commences and from there, every couple of sentences I write, it becomes a necessity to check what's in the fridge. After doing so about a dozen times, I finally discover something which I should've understood after the second time, the contents of the fridge aren't going to change anytime soon. Food isn't going to walk in there to be eaten, besides I'm on a diet at the moment.

...which like the story I'm currently writing, is failing miserably.
