Premise: 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 . This classic ketogenic diet contains a 4:1 ratio by weight of fat to combined protein and carbohydrate . This is achieved by excluding high-carbohydrate foods such as starchy fruits and vegetables , bread , pasta , grains and sugar , while increasing the consumption of foods high in fat such as nuts , cream and butter .
Hypothesis: Fat is part of a diet called Ketogenic diet.
