Keto is flexible and there are three distinct plans that target different goals.
Standard Ketogenic Diet (SKD)
This one is very low in carbs, with moderate protein, and high in healthy fats. Typically the ratio is 75% fat, 20% protein, and 5% carbs
High-Protein Ketogenic Diet
This plan is similar to SKD but includes more protein. Typically the ratio is 60% fat, 35% protein, and 5% carbs.
Cyclical Ketogenic Diet or CKD
This plan is mostly used by athletes, bodybuilders, cross-fit or anyone participating in high intensity exercise and features short periods of high carb intake. Typically they use a 5 day standard keto diet (SKD) followed by two high carb intake days.
Targeted Ketogenic Diet or TKD
This plan is also used by bodybuilders and athletes who work out regularly to fuel intense workouts. Typically this means a high carb load based around their individual workouts.
