Much of the low carb and paleo reasoning revolves around insulin. To quote one random blogger, “Carbohydrates increase insulin, the root of all evil when it comes to dieting and health.” So because carbs increase insulin, we should stick mostly to meat, which is fat and protein—no carbs, so no increase in insulin, right? Wrong. We’ve known for half a century that if you give someone just a steak, no carbs, no sugar, no starch–their insulin goes up. Carbs make your insulin go up, but so does protein.
