Hunter gatherer is not a monolithic term, and it is completly obvious that humans have adapted to inumerable diets in countless ecological nieches. We have always been omnivores and semi nomadic and in the vast majority of cases have utilised dramaticaly diffrent food sources, based on seasonal availibility, and chance oportunity. Cant see any plausable reason to make the conection that is bieng made with language.

It's not a monolithic term, but there are commonalities that define it. For example, all hunter gatherers lead at least partly nomadic lifestyles, without any fully permanent settlements (though they can have constructions they gather to, and sometimes spend significant parts of a year at). As such, they won't have, or at least not rely significantly on, things like mills or cutlery. This will mean that, in all climates, hunter gatherers will have a diet that requires much more physical effort to tear off and chew than most agricultural societies, and definitely much more so than any modern diet.
