It's really closer to 70 years ago to see the roots of the obesity epidemic in the US and had a lot to do with the post war world. To put it in another way, machines have taken over the vast majority of labor. Even people that do 'hard' jobs are still using a ton of tools that decrease the amount of physical effort they put in the job.
