6. You Get Smarter
Believe it or not, reducing your intake of sugar can actually help you to feel more vigilant, more alert, and more switched on.
Why is that?
Because when you reduce the amount of sugar in your body, your system is forced to rely on other sources of energy. This particularly means ketones that are produced in the liver and which can come from fat.
The brain actually prefers ketones for certain tasks and as a result, you feel sharper and more alert!
