Bowel movement after meals?

Again this is another embarrassing topic, but does the amount of stools i drop depend on how much i eat? For example, i eat a mcchicken and a small fry. I should expect drop a small amount, at least 1 or 2 pieces. And if i eat a big meal like at an all you can eat buffet, i should drop a huge amount like 5 or 6 pieces, right? Or does it not matter? Like if i eat a huge meal, and i drop 1 or 2 pieces in the toilet the next day, is that normal? If the pieces were smaller, is it still normal regardless if i ate a huge meal? This is what sort of is going on to me now. I fear that if i keep eating huge amounts, all the contents will be lined up in my colon, and be released one at a time on different days. This is sort of holding me back from having snacks.
