For families navigating an epilepsy diagnosis, the search for effective treatment can feel overwhelming. While antiseizure medications help many children control seizures, some continue to experience seizures despite trying multiple therapies. For these children, dietary treatment—specifically the ketogenic diet for epilepsy—may offer another option.
The ketogenic diet is a medically supervised therapy that has been used for more than 100 years to help reduce seizures. At Riley Children’s Health, ketogenic diet therapy is offered as part of a comprehensive epilepsy program designed to support children and families every step of the way.
What Is the Ketogenic Diet?
The ketogenic diet is a specialized medical diet that is high in fat, moderate in protein, and very low in carbohydrates. Unlike popular “keto” diets for weight loss, the ketogenic diet for children with epilepsy is carefully calculated and closely monitored by a medical team.
Under normal conditions, the body uses carbohydrates as its primary energy source. The ketogenic diet limits carbohydrates so the body shifts to burning fat instead. This process produces substances called ketones, which become an alternate source of energy for the brain.
The Ketogenic Diet and Epilepsy
Research shows that for some children, ketones can help stabilize brain activity and reduce seizure frequency. This is especially true for children with drug-resistant epilepsy, defined as ongoing seizures despite trying at least two appropriate antiseizure medications.
Studies over decades have shown that many children on ketogenic diet therapy experience meaningful seizure reduction. More than half of children see a 50% reduction in their seizure rate, while others may achieve seizure freedom (National Library of Medicine). In addition to seizure control, families sometimes report improvements in alertness, attention, or overall quality of life.
Is the Ketogenic Diet Safe for Kids?
When used under medical supervision, the ketogenic diet for children with epilepsy is considered safe and effective. Because an epilepsy diet involves careful nutrient balance and monitoring, it should only be started under the guidance of an experienced medical team.
Potential benefits for children may include:
- Reduced seizure frequency
- Improved seizure control when medications alone are not effective
- A non-surgical treatment option for some families
Like any medical therapy, the ketogenic diet can have side effects. Possible risks may include constipation, reflux, low blood sugar, changes in cholesterol levels, kidney stones, or slowed growth if nutrition is not carefully managed. At Riley Children’s, children on ketogenic diet therapy are closely monitored with regular check-ins, lab work, and nutritional assessments to help prevent and manage side effects early.
Expert Opinions and Research
The ketogenic diet is supported by more than a century of clinical use and extensive modern research. Pediatric neurologists and epilepsy specialists continue to study how dietary therapies affect brain metabolism and seizure control.
Today, international epilepsy guidelines recognize ketogenic diet therapy as an evidence-based treatment for drug-resistant epilepsy. Ongoing studies show that modified versions of the diet—such as the modified Atkins diet—may offer similar benefits for some patients with fewer restrictions.
At Riley Children’s, nutrition-based treatment for epilepsy is managed by a dedicated team that includes pediatric neurologists and registered dietitians with specialized expertise in ketogenic diet nutrition therapy. This team approach ensures decisions are guided by the latest research and tailored to each child’s needs.
Practical Tips for Parents
If your child is being considered for ketogenic diet therapy, there are several important steps to ensure safe implementation.
- A thorough evaluation helps determine whether the diet is appropriate. This includes reviewing seizure history, current medications, and nutritional needs. Families receive education and step-by-step guidance before the diet begins.
- Once started, children are monitored closely for seizure response, growth, lab values, and overall tolerance. Adjustments can be made to the diet ratio, meal plan, or supplements as needed.
- Most families begin the diet at home with outpatient support, allowing for a gradual and flexible transition. Parents are encouraged to communicate regularly with their care team and report changes in seizures, energy levels, or side effects.
- Support and education are ongoing throughout the process. Families on ketogenic diet therapy at Riley Children’s have access to parent support groups, ongoing education, and specialty newsletters, helping families stay informed and connected beyond clinic visits.
The ketogenic diet has a long history as a treatment for epilepsy and for some children, it may be the best diet for epilepsy when medications alone aren’t enough. When guided by an experienced care team, ketogenic diet therapy can reduce seizures, improve quality of life, and provide hope for families seeking additional treatment options.
Riley Children’s offers a comprehensive epilepsy program with expertise in ketogenic diet therapy, advanced diagnostics, and personalized care planning. If you think the ketogenic diet may be right for your child, talk with your neurologist or request a referral to the Riley epilepsy team.
