All prehistoric people in natural circumstances were thin.
Except probably not people in the far north in seasons when game was plentiful. I believe there is evidence they ate themselves fat, the way bears, deer, and other animals do before winter, in a good year when food is plentiful. This is not hard to do when you live near a river with migrating salmon, for example. Primitive people (not prehistoric, but people with tools and agriculture and some social structure) sometimes starved to death, but in other cases they were fortunate enough to be fat. Premodern Inuit people were often seasonably fat.
