What is the ketogenic diet therapy?

The ketogenic diet therapy is a specific dietary regimen characterized by high fat, low carbohydrate, and adequate protein intake. It promotes a metabolic state in the body known as "ketosis." In this state, the body primarily uses ketone bodies produced from fat metabolism for energy, rather than glucose, which is the usual energy source. This therapy was initially developed for treating drug-resistant epilepsy, especially in children. In recent years, the ketogenic diet has also been applied as an adjunctive treatment for various other conditions, including weight loss, diabetes, and multiple sclerosis.

In the ketogenic diet, dietary fat sources typically include vegetable oils, fatty meats, etc., which help meet the body's energy needs and support ketone body production. Protein intake must be controlled to ensure the body does not excessively rely on protein for gluconeogenesis (the process of converting non-carbohydrate substances into glucose), which could interfere with ketone body production. Carbohydrate intake is strictly limited, usually to no more than 5%-10% of total energy intake.

The ketogenic diet also carries potential risks and side effects, such as nutritional imbalances, constipation, and kidney stones. Therefore, it should be undertaken under the guidance of a qualified healthcare professional.
