"KETOGENIC DIET"

​What is the Ketogenic diet?


The ketogenic diet is a special high-fat diet that is used for difficult to treat seizures. Heavy cream, butter and vegetable oils provide the necessary fat. The diet also completely eliminates sweets such as candy, cookies, and desserts. Other carbohydrate rich foods such as bread, potatoes, rice, cereals, and pasta are not allowed on the strictest form of the diet, but are allowed on more liberal forms of the diet. All foods must be carefully prepared and weighed on a gram scale. Each meal must be eaten in its entirety for the diet to be most effective.


Who can be helped by the diet?


Children with seizures from infancy through the teenage years may be helped by the diet. There is no way to predict beforehand whether it will be successful. Traditionally the diet has been used for children with myoclonic, atonic and tonic-clonic seizures. In every decade since the 1920's, studies consistently show that 50-75% of children with difficult to control seizures of all types are helped by the diet. Children over the age of 5 years may find the diet difficult to follow due to its strictness. New and creative recipes have helped to make the diet more palatable in the past few years.


How effective is the diet at controlling or eliminating seizures?


The diet has never been evaluated in a controlled scientific study. Studies that have followed children on the diet for long periods reveal that 1/3 of children treated with the ketogenic diet have greater than 90% seizure control with half of these children becoming seizure free. An additional 1/3 gain a 50% reduction in seizures. The remaining 1/3 discontinue the diet due to its ineffectiveness or its difficulty.


How does the diet work?


No one is certain how the diet works. A metabolic change occurs in the body which affects brain chemistry. One theory attributes the anti-seizure effect of the diet to the ketones that the ketogenic diet produces. Ketones are the products of fat breakdown. Our body normally burns glucose (sugar) for energy. The body can use these ketones as a source of energy instead of glucose. The ketones circulate through the blood in the body and then are excreted into the urine.


How is the diet prepared?


Ketosis is produced by eating a balance of foods that provide just the right amount of fat, protein and carbohydrates. A calorie level is determined by a dietitian for each child based on their age and activity level. To achieve a desired level of ketosis, the diet is calculated in terms of ratios such as 4:1, 3:1, and 2:1. In a 4:1 ratio, there is 4 times as much fat as there is protein and carbohydrate combined. The dietitian devises meal plans that complete the required fat, protein and carbohydrate for each meal. Each meal plan indicates the exact gram weight of each food which must be weighed on a gram scale. A typical meal includes a small amount of fruit or vegetable, a protein rich food, and a source of fat such as heavy cream and butter or vegetable oil.


Will anti-seizure medications be reduced after my child goes on the diet?


If the child is on more than one anti-seizure medication, one may be reduced as the child starts the ketogenic diet. The reduction of remaining seizure medication may be made if the child's seizures improve over time. Some children are able to have their medications completely discontinued. Medications may act stronger with the ketogenic diet therefore close medical monitoring is necessary.


How do you begin the diet?


The diet is started under close medical supervision. The diet is begun gradually and increased to the full amount over a 3 to 4 day period. During this time blood sugar and ketone levels are monitored. A fasting period is not necessary to start the diet according to recent studies.


How soon does it take for the diet to reduce or eliminate seizures?


The diet can become effective immediately or can take several months. Each child is unique and has different seizure patterns and frequency. There is usually improvement within the first 10 weeks on the ketogenic diet.
