You're overthinking this. :) There's no real need to eat 4-6 meals for everyone. Some people do find that they do better with more frequent food intake, allowing them to stave off hunger and keep their metabolic furnace "stoked" as it were, but it's not necessary, and there's no reason to worry about labeling one a meal or a snack, or anything in between.
Look at your calorie range. Anything within that calorie range is pretty much okay. If you want to eat three big meals and a snack or two, that's fine. If you want to eat five or six small meals, that's okay too. Just experiment with the ranges, and don't worry about what you're labeling things.
