How could diet affect epilepsy?

After noticing that people with epilepsy tend to have fewer seizures while fasting, there was an interest in trying ketosis-inducing diets to control seizures. Limited research suggests that a ketogenic diet, a medium-chain triglyceride diet, a modified Atkins diet, or a low-glycemic-index diet may be helpful for reducing seizures in some people with epilepsy. However, a strict ketogenic diet can be challenging to adhere to long-term and can increase the risk for adverse health effects such as nutritional deficiencies, growth impairment in children, and digestive problems.^[1][2]
