You’re fine Milty.
This forum is a community, not a club for which you must do x, y and z in order to belong.
You’re of course much better off now that you’ve acquired better eating habits and understand the harm that sugar and grains do, but also understand that in order for them to wreak havoc you must have them constantly. Lowering your intake is going to help even if you never fully eliminate them.
Regarding exercise, you don’t HAVE to exercise using the PBF. Honestly speaking, I only downloaded the PBF to give it to a friend. I never once read it (I probably would benefit from doing so, don’t get me wrong) but did thumb through it and saw that the exercises do already resemble what I’m doing.
It’s not imperative for you to follow the primal blueprint down to the letter, I don’t, and I’m still much better off than I was a year ago. So don’t stress it.
