Even the term "meal" seems a bit unwarranted for most events. If I have a granola bar and a fruit shake around 3pm, is that a "meal"? What if I go browse the web for an hour, then come back and have a sandwich with some milk- is that a continuation of the granola/shake meal, another meal, a snack, are both snacks-is there any reason to care? No. Focus on eating right and eating when you're hungry. The rest should take care of itself.
