I think this follows the ideas of Pavlov's Dog (Correct me if I'm wrong) but if you eat the same type of food every time you do an activity, you come to associate the two together. So, what foods have you associated with what?
For me, I've associated Circus Peanuts with Toonami and Dragon Ball Z (such terrific days of youth), Chicken Fingers with playing pool, Licorice with playing Mass Effect, and I've grown accustomed to turning on every light in the room for the very act of eating (though only Lunch or Dinner.)
