I think everyone has their own version...
It seems like a lot of primal "treats" are posted by people with families and maybe kids and husbands that want "normal" foods. You know, kid wants a cupcake, better it be primal.
Also, baking is a legit hobby- I used to love baking and primal/paleo baking would fill that void for many people.
I mean, good for you that you can be so compliant- but some of us simply still enjoy certain foods. Mine is dairy. We are still getting many of the benefits and keeping ourselves happy. This is meant to be a long term way of life so if you really love good cheese or baking you might not want to fully abandon it.
