I don't really have a regular eating schedule - It's entirely situational. During the school term I tend to skip breakfast, and I usually have a massive lunch, some kind of unhealthy snack in the afternoon and possibly something for dinner. Outside of term I'll eat whenever anyone around me eats.
One notable exception to both of the above would have to be my week in Russia; I had some horrible stomach thing going on and I had absolutely no appetite. I actually went two days without eating a single thing, and by the end of the week I'd lost at least a stone in weight.

The food was pretty horrifying, to be honest, so that might have contributed. HERE HAVE SOME UNLABELED MEAT AND AN EASTERN EUROPEAN ROOT VEGETABLE.
Jam it back in, in the dark.
