Then how come obesity basically didn't exist until the 70s while 1 in 2 American is now obese ? Shouldn't everyone be obese ? Especially rich folks who have access to infinite amount of food

Don't you think it's a bit less simplistic maybe ?

probably more Americans spent time physically working, and not sitting 10h/d in office and another 2h in the car commuting.

I am sure there are obese rich, also rich likely in general have more willpower to control their instincts, and that's partially how they become rich.
