Your child will be admitted to the hospital before starting the diet. Your child may be in the hospital for 4 to 5 days while his or her body starts making ketones. During this time, you’ll also learn how to plan your child’s diet. You may also be taught how to test your child's urine for ketones.
While in the hospital, your child may not be able to eat for 1 to 2 days until ketones are measured in the urine. Once ketones are in the urine, your child may be given high-fat, low-carbohydrate shakes. These are also known as keto shakes. After several meals of keto shakes, your child will start eating solid foods.
