Were all hunter-gatherer diets protein and fat based? https://www.scientificamerican.com/media/inline/paleo-diet-h...

Is that percentage by weight, percentage by dry weight, percentage by calories, or something else?

And no matter which I interpret it as, all those diets are "protein and fat based" by Standard American Diet standards. Seeds and nuts are very high in fat.

This specific graphic seems to be by weight. The type of meats the Inuits eat is really high in fat.
