Hi, hreid:
I am by no means an expert on this---but aspire to one day be "good at it." LOL.
Have you bought the book yet?? It's got EVERYTHING in it you need to know. VERY helpful, if not essential.
One thing Lyle says in the book is that if you can't or don't want to do the depletion workout to do TKD instead of CKD. The workout is essential to CKD working. I didn't fully understand this until I read the book, btw. You just can't skip it.
If I were you, and I'm not of course..lol, I would get the book and go for the TKD, where you carb up ONLY immediately prior and immediately after your workout...no carb up days on weekends, etc.
Fruits are a no-no. And I've not read in full the whole TKD chapter...well, read it, but didn't "study" it, so I don't know if the sugary carbs are important for that or not, so i wont even speculate on that one.
Now, about ketosis: If you can fully carb up AND stay in ketosis the whole time----you'll be in guiness book of world records (or studied by NASA..LOL). You simply can't avoid getting knocked out of ketosis during a CKD carb up. TKD, I think you remain in, but not on CKD.
I probably wasn't much help, but it's a little bit to chew on and think about anyway.
Do get the book, though, because it spells everything out in detail---LOTS of detail!!!!
Good luck.
