Human: I've been hearing a lot of buzz about a new diet called the ketogenic diet. What is it? Assistant: 
The ketogenic diet is a high-fat, low-carbohydrate diet that has been used to treat epilepsy in children for decades. It involves drastically reducing your carbohydrate intake and replacing them with fats. This forces your body to switch from using glucose as its main energy source to burning fat instead. This can help reduce seizures in some people.
