The Claim

A low-carbohydrate, high-protein diet induces insulin resistance as a phenotypic adaptation in both humans and experimental animals, which may have evolved as a physiological mechanism to preserve glucose homeostasis during periods of carbohydrate scarcity in human evolutionary history.

How it works
1 study reviewed
In plain English

Eating very few carbs and lots of protein might make your body less sensitive to insulin — not because it's broken, but because it's adapting to save glucose when carbs are scarce, like in ancient times.

What the research says

1 study
  1. Study: The carnivore connection: dietary carbohydrate in the evolution of NIDDM

    The study says that when people or animals eat very few carbs, their bodies become less responsive to insulin to save sugar for the brain, which matches the claim. It also says this might have helped our ancestors survive when carbs were hard to find.
