Ketones – What are they?
Ketones are a beneficial product of fat metabolism in the body. When the body breaks down stored fat, it creates fatty acids, which are then burned in the liver in a process called beta-oxidation. This process results in the creation of ketone bodies, which are then used as fuel by the muscles and brain cells.
There are three major types of ketone bodies present in the human blood stream when the metabolic process of ketosis is in progress:
In times of starvation and low insulin levels, ketone bodies supply up to 50% of the energy requirements for most body tissues, and up to 70% of the energy required by the brain. Although glucose is the main source of fuel for neurons when the diet is high in carbohydrates, these fatty acid fragments are used preferentially by brain cells when carbohydrate or food…
