US FDA nutritional guidelines are based on 2,000 kilocalories a day. Europeans use kilojoules to the same effect.

I'm not sure any food in the USA uses a single calorie as a measurement of anything, because kilocalories make more sense in terms of units of scale in the human diet.

2000000 of anything sounds like a lot, so why not use prefixes to simplify?

According to the FAO, the average minimum daily energy requirement is approximately 8,400 kilojoules (2,000 kcal) per adult and 4,200 kilojoules (1,000 kcal) a child.[3] This data is presented in kilojoules, as most countries today use the SI unit kilojoules as their primary measurement for food energy intake,[4] with the exception of the USA,[5] Canada,[6] and the UK, which use kilocalories or both.

That's why you either use kcal (or Cal) or kJ, but not Mcal (or kCal, which is easily confused with kcal) or MJ, because most things you eat and drink are between 0 and a few hundred kcal. This way you have one unit and keep it consistent instead of switching between kcal and Mcal all the time or saying awkward stuff like you ate something that only had 0.004 Mcal.

Europeans use kilojoules to the same effect.

While kJ is required in labeling in Europe most people still use kcal for everything. AFAIK the only country somewhat consistently using kJ is Australia (the one with the kangaroos).
