A ketogenic food is a properly formulated diet high in fat, low in carbohydrates, protein and other nutrients.

2. A ketogenic-diet (KD), usually a diet that is very low in carbohydrates, moderate in protein, and high in fat, is designed to induce ketosis, or the production of ketone bodies. Ketone bodies serve as an alternative energy source for neurons and other cells that cannot directly metabolize fatty acids, and urinary ketone levels are often used as an indicator of dietary compliance. The "classic" ketogenic diet is usually a medically supervised, very low-carbohydrate diet with a 4:1 or 3:1 ratio of dietary fat to dietary protein and carbohydrate.

3. The ketogenic diet began with the observation that starvation reduces seizures. Long ago, Hippocrates used starvation therapy to treat epilepsy, and Bible mentions starvation therapy as a method of epilepsy treatment. This therapy was used for decades in the 19th century to treat refractory epilepsy in children.

4. In September 2021, researchers from the American Association of Accountable Physicians, New York University, the University of Pennsylvania, George Washington University, and Bellevue Hospital in New York conducted a comprehensive evaluation of the ketogenic diet, weighing the pros and cons of the ketogenic diet in relation to chronic disease, and concluded that the risks of the ketogenic diet outweigh the benefits for the majority of people.
