>> It's bizarre to me that people don't look after their health.
The obesity crisis obviously has multiple causative factors.
There are plenty of natural experiments suggesting that some of these factors are beyond human behavior and more systematic or environmental (e.g., hormones in food, etc)
There are probably also societal drivers like overpopulation which leads to sprawl, longer commutes, more sedentary time, greater reliance on cars.
I am not saying people should not hold themselves responsible, but we should not be quick to pin it all on individuals and should look at outsider factors also.
