Keto Advantage Keto Burn : As we mentioned earlier, a keto diet is high in fat, moderate in protein, and low in carbs. The ketogenic diet is a diet that produces reactions in the body similar to those that occur during fasting. This is a type of extreme low-carb diet that was first developed in 1921 due to the ability of this type of diet to reduce or suppress seizures. As new medications to treat seizures were developed, the ketogenic diet became less popular as a way to manage seizure disorders.
