Obesity driven by overconsumption of protein-mimicking carbs and fats

Then your analogy was the wrong way around. As a society, we
didn’t take the benches away, we put benches everywhere.

Nearly everyone living in the Western world has the means to eat more healthy, indeed live more healthy. The details vary from county to country, though. If they don’t want to do that, that’s okay. They can also expect not to be mocked or ridiculed if they happen to be obese. But the constant excuses are not helping.
