Welp, RWS, first I'll have to point out that there haven't been any studies done on this directly, so any discussion is purely speculative or anecdotal.
Anyway, my issue with it has to do with glycogen resynthesis. TKD just makes a lot more sense. If you carb up for 2 days, you only store so much, and given the numbers Lyle and others cite for glycogen depletion per set of exercise (and what I think is the excessive # of sets you do
- lots in any case), basic arithmetic shows that you use up your entire carb up in the first workout, or the first two assuming his numbers are exxagerated. This means, even if one of your workouts falls within the carb-up window, that the for the other one or two you're running on the relatively tiny amount of glycogen your body can produce during the no-carb portion of the week, which is certainly not ideal for performance and muscle synthesis. You recommended the Ketogenic Diet, and I read it twice, and Lyle is pretty firm about keto being crap for bulking in any case, and cyclical keto particularly; I think he makes a good case for it.
The reason I say it (CKD) is more for advanced lifters is because of the belief that their bodies are more adapted to the activities and better able to create and utilize glycogen stores effectively, mitigating the above issue.
But if you are going to try it, it should be on TKD. I know that as soon as it's been two weeks for me I'm gonna start taking carbs around the WO window, and 0 carbs any other time. My fat loss might not be quite as good, but it'll be worth it to be able to work out harder. In your case, though, on a bulk, there's no actual downside to TKD rather than CKD as far as I can tell.
Except for not getting to eat your oatmeal and whatnot, but for me that's not an issue, as I don't like eating grains.
