I wouldn't go so far as to say that it is dangerous ... It is actually a pretty good balance and still remains effective at producing results.

I won't get into the deep biochemistry of it, but using a CKD does have benefits to the hard training fitness enthusiast/athlete that a standard LC diet does not offer. If you want me to get specific, let me know. I don't want to bore anyone needlessly.

But, as the disclaimer goes, everyone's body is different and people all react differently to changes in diet. I have never seen a case of a CKD producing negative effects on health though ...
