Ketogenic diet has protein.
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 original therapeutic diet for paediatric epilepsy provides just enough protein for body growth and repair , and sufficient calories to maintain the correct weight for age and height . This classic ketogenic diet contains a 4:1 ratio by weight of fat to combined protein and carbohydrate . As less overall fat is needed in this variant of the diet , a greater proportion of carbohydrate and protein can be consumed , allowing a greater variety of food choices .
