Before doing anything else, Read and understand the PB 101 info at Primal Blueprint 101 | Mark's Daily Apple. Read enough of the subjects covered that you understand the program you are looking at, don't spend money on the book just yet.
The answer to your question is yes, but initially you may not think the suggested treats are quite to your prior taste.
Going primal is real change in most people's whole lifestyle. In my opinion, the worst way to start off on Primal is to go in trying to figure out how to treat yourself, and/or how many "cheat meals" you can have. I suggest that if this is where you are, you either need to re-orient or save yourself some frustration and pass it up. But keep in mind that if you do Primal, you will likely lose whatever excess poundage you have, much faster than how long it took to put it on. Not to mention that you will generally feel a whole lot better, and you will most likely be shopping for smaller clothes in a few months
The Buck stops here. I am responsible for my past and my future. So for today: I choose to be happy. I will seek wisdom. I will be a servant to others. I will greet this day with a forgiving spirit.
