I've been hearing a lot about a new diet fad. What's it all about?

The latest diet fad is called the ketogenic diet. It involves eating a high-fat, low-carbohydrate diet that forces your body to burn fat for energy instead of carbohydrates. This type of diet has been used to treat epilepsy and other neurological conditions since the 1920s, but recently scientists have discovered that it can also help with weight loss.
