What percentage of the population had desk jobs before 1960? Standing/moving all day burns a lot of calories, I would assume enough so that you don't put on a few pounds each years which can lead to obesity in the 40s. Of course that's not all the population, some are obese before being teen. But I think that's still an important part. You can't outrun your stomach if you eat a surplus of 2000 calories each day, you can if you eat a surplus of 200.
