When the body burns (metabolizes) fat, it creates substances called ketones. The ketogenic diet tries to force the body to use more fat for energy instead of sugar (glucose) by increasing fat and restricting carbohydrates. It is not yet clear how or why the ketogenic diet prevents or reduces seizures, but it has been shown to be effective in reducing epileptic seizures in some children.1
One version of the ketogenic diet provides 4 grams of fat for every 1 gram of protein and carbohydrate together. People on a ketogenic diet have to eat mostly fatty foods, such as butter, cream, and peanut butter. Foods such as bread, pasta, fruits, and vegetables have to be severely limited. And the person's total calories and fluids are also restricted. At every meal, the food has to be measured carefully so that the right amounts of each food are given. Even a slight departure from the diet can cancel its effect.
