Three times a day is certainly not a hard rule - its just a habit.

During busy times at work, I can get down to once every other day. Its not hard. Its all about being distracted from hunger long enough to put it in the background.

As for how often we 'need' to eat, that's not clear. Three times a day is absolutely a made-up number. Cultural, not biological. And of course how many snack all day long? How many 'meals' is that?
