A ketogenic diet is one of the treatments for epilepsy when conventional methods such as anti-epileptic drugs are not effective in controlling seizures. If you or your loved one is suffering from epilepsy, you may be wondering if a ketogenic diet is effective and if it could be the right solution. Here, we have explained what a ketogenic diet for epilepsy comprises and whether it will be beneficial.
Since the 1920s, the ketogenic diet has been used as a treatment for epilepsy. The diet is highly specialized and is only recommended when other treatment options for epilepsy are not working. A ketogenic diet is a standard treatment for children who are suffering from difficult-to-treat epilepsy. However, this form of treatment has also gained traction amongst adults.
The ketogenic diet for epilepsy is strict and contains extremely low amounts of carbohydrates. However, it is rich in fats and comprises just the right amount of protein for supporting body growth and maintenance. The breakdown of fat by the body produces ketones that can then be used by your brain to generate energy instead of using glucose(carbohydrate) for energy production. While designing a ketogenic diet, the appropriate amount of protein intake will be determined first. This is usually done based on factors such as age. After this, the dietitian will design the diet as a ratio of fat, protein and carbohydrate grams. Generally, a 4 to 1 ratio is taken as a starting point and then adjusted accordingly.
Though the exact mechanism by which a ketogenic diet controls seizures is not completely understood, studies have indicated that the ketogenic diet works because of the following reasons:
To determine if a ketogenic diet is right, the neurologist will consider if you or your child is eligible for it. Besides this, you should also know the pros and cons of a ketogenic diet and discuss these with the neurologist to see if going on the diet would be beneficial. The right team of well-trained neurologists and dietitians can ensure that the treatment is highly beneficial.
The ketogenic diet for epilepsy treatment is generally considered suitable under the following conditions:
Research suggests that at least a third of children with epilepsy who have followed this diet will see a reduction in seizures by at least 90%. The remaining individuals will see a reduction of between 50-90%. This data is highly encouraging as most of these patients had seizures that were poorly controlled by medicines. There have been many trials showing the effectiveness of a ketogenic diet in reducing the frequency of seizures in children. Similar studies in adults have also shown promising results.
A ketogenic diet for epilepsy can also have certain side effects, such as
If you have decided to start your child on a ketogenic diet for the seizures, your child will be admitted to the hospital, and his/her health will be monitored once the diet begins. Usually, the healthcare team will consist of medical experts such as a dietitian and neurologists. It is advisable that you do not try to start the diet by yourself. You should first discuss the keto diet with the neurologist to see if it would be beneficial.
