Loss less muscle? That implies muscle loss. I have no trouble gaining size and strength on a CKD. I'm believe such eating plans have the potential to create a MORE anabolic environment than a conventional high carb mass building diet. Those of you who say you felt horrible on a CKD, I suspect the reason is that you did not stick it out for 2-3 weeks, did not eat enough fat, and were difficient in EFA's because you focused too much on chesse, eggs and steak and didn't drink flax seed oil and other sources of EFA's in massive quantities. Actually the body's prefered fuel source is polyunsaturated fat (n-3 and n-6), and it will run more efficiently on them than it will glucose. Just my 2 cc's...
