The real Paleolithic diet was probably omnivorous and highly variable
US,
Our ancestors ate a Paleo diet. It had carbs."...We evolved as hunter-gatherers, so you’re hunting and gathering whatever foods are around in your local environment. Humans are strategic about what foods they go after, but they can target only the foods that are there. So there was a lot of variation in what hunter-gathers ate depending on location and time of year.
The other thing is that, partly due to that variability, but also partly due just to people’s preferences, there’s a lot of carbohydrate in most hunter-gatherer diets. Honey was probably important throughout history and prehistory. A lot of these small-scale societies are also eating root vegetables like tubers, and those are very starch- and carb-heavy. So the idea that ancient diets would be low-carbohydrate just doesn’t fit with any of the available evidence. ..."
