You know the feeling. You’re staring at a basket of warm bread or a bowl of fruit, and the diet culture guilt washes over you. You hear the echo of a keto influencer in your head: Carbs are unnatural. Our ancestors didn’t eat this. But what if everything you were told about the ‘caveman diet’ was fundamentally wrong?
We’ve been sold a myth that early humans were hyper-carnivores who only touched carbs by accident. The truth is far sweeter. Early human brain expansion was likely fueled by access to sugary, carb-rich plant foods. We didn’t get smart by restricting carbs; we got smart because we found them.
Think about the classic image of the paleo dieter: a man with a spear, bringing home a mammoth. It’s a rugged, hyper-masculine fantasy that completely erases reality. The bulk of early human calories didn’t come from the men risking their lives on a hunt. It came from the women and children gathering fruit. The popular hunter-centric paleo narrative doesn’t just use bad science—it erases the women and children who actually fueled our evolution.
So why do we get sick from sugar today? It’s not the molecule’s fault. If you’re constantly moving across the savanna, sugar is a biological necessity for maintaining glycogen. The same molecule that powered human cognition now drives metabolic disease when divorced from its original context.
The keto and paleo crowds have it backward. They want the metabolic benefits of our ancestors without doing the actual work of our ancestors. Sugar isn’t the villain. Sedentary living is.
The next time you eat an apple or a piece of chocolate, you don’t need to repent. You aren’t betraying human nature; you’re embracing the exact fuel that made you human. Just make sure you earn it. The real ancestral lesson isn’t ‘eat meat’ — it’s ‘move constantly, then eat sugar.’
FAQ
Q: But doesn't sugar cause insulin resistance and diabetes?
A: In excess, yes. But the issue is abundance without movement. If you are sedentary, a high-sugar diet is toxic. If you are constantly active, your muscles act as a sponge for that glucose. The context dictates the harm.
Q: So I can just eat donuts all day and blame my genetics?
A: No. It means you should stop viewing carbs as 'unnatural' or 'evil.' But it also means you can't sit at a desk for 10 hours and expect your body to process them like a hunter-gatherer. You have to earn your carbs through physical movement.
Q: Is the Paleo diet actually bad for you?
A: Not physically, but ideologically. It’s built on a myth that erases the gathering half of humanity. It turns a complex, highly active history into a meat-heavy fantasy that justifies modern overconsumption of animal products.
