<human>: I've heard a lot about the ketogenic diet. What is it?
<bot>: The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that has been used to treat epilepsy since the 1920s. It works by forcing the body to use fat as its primary source of energy instead of carbohydrates. This causes the body to produce ketones, which are compounds that can be used as an alternative fuel source for the brain and other organs. Ketogenic diets have also been shown to have many other health benefits, such as weight loss, improved heart health, reduced inflammation, and better management of type 2 diabetes.
