>Just watch one of those old “Berlin in the 1920s” or “NYC in the 1970s” videos. You’ll quickly notice the almost complete lack of overweight people.
Being fat in the 80s is being skinny today. It's uncanny rewatching movies where the fat kid everyone picked on then would be on the average to skinny side today.
Whenever I bring that up I get someone popping out of the wood work saying that the 80s had heroin chik, unrealistic body expectations and on and on.
But the fattest state in 2000 (Mississippi) is skinnier than the skinniest state today (Colorado) [0]. And in 1990 the fattest state (again Mississippi) was half as fat as Colorado is today.
Forget being transgendered the majority of the US would look barely human to anyone from the 80s.
