I'm not sure about the other traditions, but eating foods with a high amount of carbohydrates (especially sugar) for dinner in my experience isn't a good idea. Even fruit. It raises your blood sugar, so when your blood sugar drops again you find yourself hungry. It happened to me a quite a few times that I woke up in the middle of the night in desperate need of sweets. If don't eat sweet things in the evening this doesn't happen. Obviously this only speaks against eating "breakfast" for dinner but not against eating "dinner" for breakfast. Which seems to be what English Breakfast is all about. ;-)
