We're definitely a big proponent of a psychological approach for a lot of Fellas. And "food addiction" is a controversial but rapidly growing area of research.

That said, important to state a psychological-only approach sadly isn't sufficient for the majority of people.

I've never looked for research on this, but the environmental & social pressures are definitely believable why they may produce this outcome. I also wonder how important selection effect is here for your Bondi Beach example.
