"The simple truth of natural nutrition" is scarcity and starvation. Obesity is a result of the ready availability of the kinds of foods (carbs and fat) that are "naturally" hard to get, so our body hoards them when it has access. We innovated ourselves into effectively unlimited food. All diets are unhealthy if access isn't limited.

I like not going hungry on a regular basis. Most people do.

Most healthy people I know aren’t chronically hungry. You’ll be chronically hungry if your diet consists of simple carbs (white bread, soda, chips).

I mean hunger from a lack of available food, not from eating food that overstimulates your systems (the simple carbs). The solution to this is primarily education (so people make healthy choices), and availability of healthier alternatives.

That said, all of civilization is built on the ready availability of refined carbs brought about by agriculture. This isn't a modern phenomenon. The only modern thing is that suddenly our food production is outstripping population growth for the first time in ever.
