The ketogenic diet concept is becoming increasingly popular among those who are fans of low carb diets. The ketogenic diets are high in fat and protein and low in carbohydrates and have been in existence for as much as 90 years. The name of the diet comes from the term “ketosis”, which is said to have similar effects to fasting.
Ketosis is the process of burning fat for energy. The process is activated when the body doesn't have enough glucose available to use as energy and insulin levels are low, so ketones produced by the liver from fatty acids are released in the bloodstream and are being used as energy.
