There are several versions of the keto diet. The information in this article mostly applies to the standard ketogenic diet (SKD), although many of the same principles also apply to the other versions. Cyclical or targeted ketogenic diets are more advanced methods and primarily used by bodybuilders or athletes. However, only the standard and high protein ketogenic diets have been studied extensively. The ratio is often 60% fat, 35% protein, and 5% carbs. High protein ketogenic diet: This is similar to a standard ketogenic diet, but includes more protein.Targeted ketogenic diet (TKD): This diet allows you to add carbs around workouts.Cyclical ketogenic diet (CKD): This diet involves periods of higher carb refeeds, such as 5 ketogenic days followed by 2 high carb days.It typically contains 70% fat, 20% protein, and only 10% carbs ( 9). Standard ketogenic diet (SKD): This is a very low carb, moderate protein and high fat diet.There are several versions of the ketogenic diet, and what you eat depends on the type.
