Your child will typically be admitted to the hospital before starting the diet. They may be in the hospital for 4 to 5 days while their body starts making ketones. In some circumstances, the diet is started as an outpatient. 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.
Fasting is not usually necessary unless urgent seizure control is needed. Once ketones are in the urine, your child may be given high-fat, low-carbohydrate shakes. These are also known as keto shakes.
