I had a personal trainer for a short period who had me on a modified paleo diet. Actually now that I think about it, it seemed more like paleo/primal; I could still have *some* dairy, but limited - yoghurt, goat's cheese and cottage cheese were ok and that was it. No beans, no grains, no peanut butter
(peanuts are a bean).
I was skeptical and not interested in losing weight. You see I finally gave up that notion when after 2.5 years NOT A POUND ONE was lost from this body, regardless of all the different tactics I had attempted.
In combination with strength training and cutting out a few things from my diet (that I said I would NEVER do) THE PLATEAU WAS BROKEN. I have continued experimenting with certain things - some rice, corn and gluten-free products (my own baking as not a lot is available where I live) and I have lost probably 10lbs since February. It's slow, but it's ok. Plus I've done other things that are suggested by Robb Wolf (the Paleo Solution) like GET ENOUGH SLEEP, sleep in a dark room, remove electronics, TV, computer, phone before going to bed.
I did see a specialist some time ago about my "problem" and he did say that probably my body was producing too much cortisol. I truly believe that eliminating these few things from my diet is helping me slowly get my hormones back on track.
I'm not saying it's the only way, but something I have learned from all of this (and I'm a veteran!) is to be open to EVERYTHING even if it means giving up - gasp! - bread. It's not the end of the world actually and there are so many wonderful options out there.
I'd rather feel good and healthy and rested and fit than have a sandwich, a donut, cake, <insert bready substance here>. Seriously. Be willing to try things within reason.
