Keto diets mainly involve the drastic reduction of one’s carbohydrate intake, and replacing it with fats. Reducing the carb content like this puts the body in a metabolic state known as ketosis.

Keto diets can have several health benefits, such as reduced blood sugar and insulin levels. However, they can also come with side effects that we will discuss later.

In this state, your body is able to efficiently burn fat for energy. It can also convert fats in the liver into ketones. This helps supply energy for the brain.
