I think a pitfall of the Zone is too many carbs too often. Not necessarily too many carbs overall. Try Robb's approach of putting half your carb blocks in the PWO window. If your insulin sensitivity is so damaged that you can't handle them, that's one story, but they don't need to be discounted completely. Keeping carbs around your workout time helps to manage things a little better and makes other meals easier to prepare.
For the record, I lean out quickest going ketogenic, but performance sucks in ketosis, or near it and I can still lean out well keeping carbs targeted around workouts.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
