The ketogenic diet, also known as the “keto diet,” is a low-carbohydrate, high-fat diet that works by drastically reducing the body’s intake of carbohydrates and increasing its intake of fats. This change in macronutrient intake puts the body into a metabolic state called “ketosis,” in which it begins to burn fat for fuel instead of carbohydrates.
Normally, the body uses glucose (a type of sugar) as its main source of energy. When carbohydrate intake is restricted, the body starts breaking down stored fat into molecules called ketones, which can then be used as an alternative energy source. In this state, the liver produces ketones from fatty acids in the body and they are then transported to the brain, heart and muscles to be used as energy.
The idea behind the ketogenic diet is that by drastically reducing carbohydrate intake, the body is forced to burn stored fat for energy, leading to weight loss and improved health markers. Some studies have suggested that the ketogenic diet may be effective for weight loss, improving blood sugar control, reducing the risk of certain neurological disorders, and even slowing the growth of certain types of cancer cells.
It is important to note that the ketogenic diet should be followed under the guidance of a healthcare professional, especially if you have any medical conditions, or are taking any medications, to ensure it is safe and appropriate for you, and to get personalized advice.
