What are the amounts of servings allowed to be eaten during keto diet?

Sure about this one?: The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that in medicine is used primarily to treat difficult-to-control (refractory) epilepsy in children. The diet forces the body to burn fats rather than carbohydrates. This is NOT a diet designed for routine weight loss! Reference: http://en.wikipedia.org/wiki/Ketogenic_diet
