Still, eating something in between is important to avoid wild sugar peaks and helps improving cognition performance if your job is intellectual. I am not sure if this is true. I think in people without diabetes, insulin does it's job and regulates your blood sugar pretty well during a fast and I think cognition is better when a large amount of your body's resources are not being used to digest food.
