A person on a ketogenic diet needs a food chart showing protein content because the diet requires strict measurement of calorie, fluid and protein intake. These diets are specialized, high-fat, low-carbohydrate diets and are administered by dieticians, reports the Epilepsy Foundation.
The human body produces ketones when it burns fat for energy. They are present in the body in the urine, blood and breath. Higher ketone levels have not been proven as a causative factor, but a correlation between increased levels and improved seizure control has been demonstrated, reports the Epilepsy Foundation.
A typical ketogenic diet is the long-chain triglyceride diet, which allows for 1 gram of carbohydrate or protein for every 3 to 4 grams of fat, according to the Epilepsy Foundation. Doctors prescribe this type of diet to patients with epilepsy when seizure medications prove ineffective.
Doctors are less likely to prescribe a ketogenic diet to an adult patient because the restricted food choices make the diet difficult to follow, although studies indicate its efficacy is the same for adults and children, the Epilepsy Foundation explains. More than 50 percent of children placed on the diet experience at least a 50 percent reduction in seizure activity, and 10 to 15 percent of them become seizure-free.
