Couple of points here.
Duchaine was a genius, and Body Opus is a great book. But many guys dont fully understand it, and the imprtance of the carb-up.
Anyone seriously considering a CKD should read Lyle MacDonald's "The Ketopgenic Diet". It picked up where BodyOpus left off, in terms of real data and scientfic verification through experiements.
For example, it DOES matter how many cals you eat during the low- (no) carb periods. You cant pig out on EVERYTHING with no limits. Granted, most guys have their appetite blunted wheil in ketosis, so they don't eat as much anyway, but still - the point that you can eat "all you want" while in ketosis and still lose weight is NOT true.
The main benefit of ketosis is that given a caloric deficit, you will burn a bit mORE fat and lose a bit LESS lean mass than you would on a ,ore balnced diet with the same caloric deficit.
And . for TX, regarding DNP ...
I too like DNP, and did an extended low-dose cycle of it, and I would have to disagree with you on how uncomfortable it is vs doing a CKD. I DID have sides, and it go quite ridiculous, even on 200 mg/day of DNP. Each person may be different in their own experiences of DNP and CKDs, but to make a blanket statement that DNP is more comfortable, and implying that this would be true for everyone, is simply NOT true.
