Ketogenic diet therapy, a diet high in fat, low in carbohydrates and moderate in protein, accelerates the metabolism of fat to ketone bodies, and in the absence of carbohydrate function, fat gluconeogenesis, which produces glycerol that is converted to sugar, a process that produces ketone bodies that are excreted in the urine for the purpose of treating disease or weight loss. Ketogenic diet therapy is thought to treat refractory epilepsy in children, glucose carrier protein 1 deficiency, and pyruvate dehydrogenase complex deficiency. A ketogenic diet is a high-fat, low-carbohydrate and appropriate protein diet that simulates a state of starvation in the body. The ketone bodies produced by fat metabolism can be used as another body energy supply to the brain to combat disease. However, ketogenic diet therapy should not be used casually, but requires strict medical advice and the selection of appropriate ingredients, generally based on natural ingredients. The effect of ketogenic diet varies from person to person, not all patients will have a better treatment effect when applying this therapy, and some people may even have adverse reactions. Some people choose this method with the goal of weight loss, and prolonged use may lead to menstrual disorders and malnutrition, etc. It is recommended that a balanced diet and regular exercise be used to keep in shape.
