I've been hearing a lot about the keto diet. What is it and how does it work?

The keto diet is a high-fat, low-carbohydrate diet that has been used to treat epilepsy in children and adults for decades. It works by forcing the body to use fat as its primary energy source instead of carbohydrates. This can help reduce seizures in some people. However, there are potential risks associated with the diet, such as an increased risk of heart disease, so it should only be used under the supervision of a medical professional.
