Not carnivores, necessarily, but there's evidence that we evolved on a
meat-heavy diet virtually devoid of grains, beans, and other
concentrated carb foods. An article in The American Journal of Clinical
Nutrition in March, 2000, reported on a multi-university, multi-national
study of hunter-gatherer diets, both from paleoanthropological evidence,
and study of the few remaining hunter-gatherer groups, and concluded
that hunter-gatherers generally get over half their calories from animal
foods, with the rest coming primarily from vegetables.  It specifically
said that "protein was elevated at the expense of carbohydrates."
