I was wondering if folk had set times for their packs or just had them when they felt hungry. I don't have an exact time but don't eat lunch before 12 or it would get earlier and earlier. And I don't have my afternoon bar till at least 3 o'clock. As for planning sometimes I have an idea of what I'm having and sometimes I'm not sure or change my mind at the last minute. But if I get into a routine it makes the plan easier to follow.
