What is the ketogenic diet

On the keto diet, you don’t count calories. You count carbohydrates
and adjust the intake of carbs vs. fat and protein. A typical keto diet
will get 60 percent of its calories from fat, 15 to 25 percent of
calories from protein, and 25 percent of calories from
carbohydrates. The only limitation on the diet is sugar, which you
need to avoid.
