I use a CKD because it works for me.

If it ain't broke, then don't try to fix it.

But then again, I am pretty much anti-TKD, but to each his own.

I like the idea of supercompensation on the weekends, which the TKD lacks, since total depletion never truly occurs. I feel my muscles get fuller when I carb-up.

When one looks at the design of the CKD, in its true form, yoi will see that it is very specific and very regimented as to what you have to do each day -- workouts and nutrition.

If you think a CKD is easy, you aren't doing it by the book. It is one of the most structured and "un-fun" diets around.

But, it is the most effective diet I have ever been on.

In my opinion, it is the perfect fat loss/muscle sparing plan available.

Fat loss is pushed ahead at light speed. Strength is maintained due to the Monday workout when glycogen is high. Due to the keto diet, muscle is spared due to the high protein/fat intake. Hormone levels are optimized.

Due to the lengthy carb-up, T3 levels are never compromised. the muscles store more glycogen in response to depletion, which in turn enables you to push harder come Monday -- hence, improved performance.

Anyway, THAT is why I do a CKD.
