Just look at your methods. Mark advocates 50-100g of carbs a day for fat loss and 100-150g of carbs a day. You're doing keto, and he specifically says he doesn't recommend long term keto due to the lack of vegetables. You yourself aren't following the ideal Primal path because something else works better for you. Carb cycling is the same. I use sweet potatoes for a carb refeed, so it's still a Primal food. It just isn't the optimal Primal lifestyle. That's not bashing it in any way. It's a modification while still staying within the guidelines.
Like I said, I'll be doing a refeed this weekend myself.
