I can attest that i definitely eat less than 2000 kcal per day on average. But:

I read a study (done by the CIA, ironically) a while ago that said sth like the average caloric intake for americans is like 4400 kcal/day, while for USSR people it is 4200 kcal/day, and concluded that people in the USSR eat healthier.

The study was done in the time of the USSR.

I’m gonna look for it now.
