There are several versions of the ketogenic diet, including:
- Standard Ketogenic Diet (SKD): This is a very low-carb, moderate-protein and high-fat diet. It typically contains 75% fat, 20% protein, and only 5% carbs).
- Cyclical Ketogenic Diet (CKD): This diet involves periods of higher-carb refeeds, such as 5 ketogenic days followed by 2 high-carb days.
- Targeted Ketogenic Diet (TKD): This diet allows you to add carbs around workouts.
- High-Protein Ketogenic Diet: This is similar to a standard ketogenic diet, but includes more protein. The ratio is often 60% fat, 35% protein, and 5% carbs.
However, only the standard and high-protein ketogenic diets have been studied extensively. Cyclical or targeted ketogenic diets are more advanced methods and primarily used by bodybuilders or athletes.
