To the OP either you are primal or not...ffs stop trolling.
A lot of people have eaten the SAD diet and gained a shit load of weight so of course you are going to hear about those success stories of people loosing weigh effortlessly by going primal.
Like you I have no major issues with wheat/grains but man cutting them out, major energy, dropped 13lbs (now 180lbs and 12% bf at an age that puts me in my late 40s). Just because I have no issue with them does not mean they are good for me.
FFS I sure there is vegetrarian/grainatarian site that you can go to and you can all pray to the gmo corn and the heavily modified wheat so go there and have fun, and leave those of us who know better alone.
