> what happens once you reach 4560 calories?

There are loads of videos on YouTube of what happens. You may or may not want to watch them. Spoiler alert: you vomit when you eat too much.

The vomit limit is probably higher than 4560 (which BTW has a suspicious number of significant digits), there might be a range between too many calories and vomiting where your body breaks down the food into waste without digesting any more nutrients/calories. Kinda like how if you eat too much vitamin C, you’ll just pee most of it out.
