KETOGENIC DIET Meaning and
Definition
-
A ketogenic diet is a low-carbohydrate, high-fat dietary approach that promotes the utilization of fat as the primary source of energy, leading to a state of ketosis. Ketosis is a metabolic state where the body produces ketones, which are byproducts of the breakdown of fats in the liver, to be used as an alternative fuel source. By limiting carbohydrate intake, typically to less than 50 grams per day, and increasing fat consumption, the body is forced to switch from relying on glucose (derived from carbohydrates) to using fat as its primary energy source.
The main aim of a ketogenic diet is to reach and maintain a state of ketosis, wherein the body becomes highly efficient at burning fat for fuel. This dietary approach is commonly used to assist in weight loss, optimize metabolism, manage diabetes, improve mental clarity, and enhance athletic performance.
Foods that are rich in healthy fats such as nuts, seeds, avocados, coconut oil, and olive oil make up the cornerstone of a ketogenic diet. Protein sources, such as meat, fish, eggs, and dairy products, are also consumed, while carbohydrates from grains, sugars, starchy vegetables, and most fruits are significantly limited or eliminated. Adhering to a ketogenic diet requires careful food choices and diligent monitoring of macronutrient intake to ensure the desired state of ketosis is maintained.
Etymology of KETOGENIC DIET
The word "ketogenic" is derived from the Greek word "ketos", meaning "ketone", and the word "genic", which is derived from the Greek word "genēs", meaning "producing" or "generating". Together, "ketogenic" refers to a diet that induces a state of ketosis, where the body produces ketones as an alternative fuel source due to a limited supply of carbohydrates or glucose.
