What all of these types of the keto diet have in common is their goal to get your body into the natural metabolic state of ketosis so you can burn fat, instead of carbs, for energy.
Standard ketogenic diet (SKD)
Consuming a high-fat, moderate-protein and low-carb diet. The percentages of your daily diet should be about 75% fat, 20% protein and 5% carbs.
High-protein ketogenic diet
Similar to the SKD, but with added protein. The ratio is about 60% fat, 35% protein and 5% carbs.
Cyclical ketogenic diet (CKD)
Involves 5-6 days of the SKD followed by 1-2 days of refeeding days where the majority of calories come from carbohydrates.
Targeted ketogenic diet (TKD)
Eating carbohydrates around the times that you exercise. Meant for people who are regularly working out at a very high-intensity or for an extended period of time.
