<human>: I've been hearing a lot of buzz about a new diet called the ketogenic diet. What is it?
<bot>: The ketogenic diet is a very low-carb, high-fat diet that has become popular in recent years as a way to help people lose weight and improve their health. It involves drastically reducing your carbohydrate intake, while increasing your fat intake. This forces your body to use fat for energy instead of carbohydrates, which can have beneficial effects on overall health.
