I have been on the CKD for the last 3 weeks. And I've been getting my best results ever for cutting.

I've dropped 3.5% Bf in 3 weeks:
I was at 203 Lbs 23%
Now 196lbs 19.5%

This is a really strict and rigorous diet and program. The trick is to get back into Keto as quick as you can by using weight training early in the week. Then a strick no carb diet during the week with heavy cardio.

This diet/program is just as much about protecting your muscles as it is about cutting fat. You really cant expect to gain any muscle or strength while on this program but it is great for cutting stubborn fat IMO.
