There are different versions of the Keto diet, like: (a) Standard Ketogenic Diet (SKD): This is an extremely low carb, moderate protein and high-fat diet, typically consisting of 70% fat, 20% protein, and just 10% carbs. (b) Targeted Ketogenic diet (TKD): This diet consists of periods of higher carbs refeeds, like five ketogenic days followed by two high carbohydrates days. (c) Cyclical Ketogenic diet (CKD): On this diet, there are periods of higher-carb refeeds, like five ketogenic days followed by two high-carb days. (d) Targeted ketogenic diet: This diet is all about adding carbohydrates around the workouts. This high-protein ketogenic diet is similar to a standard ketogenic diet but also includes more protein. Here the ratio is often 60% fat, 35% protein, and 5% carbs.  Remember that only standard and high protein ketogenic diets have been extensively studied. The Targeted and Cyclical ketogenic diets are more advanced and are used primarily by athletes or bodybuilders.
