The very point I'm trying to make is that human nature has not changed in the past 120 years. What has changed is the social and technological context in which we live.

Take a group of people from the 1900s and drop them in to the US in 2022, they would likely experience obesity at similar rates.

It's not that people made more virtuous choices in 1900, it's that food was scarcer, less palatable, and more nutritious, and physical activity was a part of daily life.

A busy suburban parent in a 2-income household did not need to squeeze in time to make a home-cooked meal and a Peloton workout around a 9-5 desk job with an hour+ car commute.
