I'm not one of those people that needs to eat at precise intervals or even every day. I just eat when in hungry for something.

In summer dinner is usually my first (and often only) meal.
I almost never eat breakfasts (especially if I woke up "only" a few hours ago). Never could, even parents wanted me to but I just had better days without breakfast as a kid so they stopped insisting.

I assume that when I travel I have access to food basically everywhere or else I know I have to plan that - which again I do in a way that I eat when I want.
