Hi Skar,
(Short answer: yes!)
When I went gluten free I slowly realised that most other grains also bother me, as in they bloat me, make me break out and make me crave starchy, sugary foods. If I have a corn tortilla or sushi with rice within 10 mins I have a little pot belly and within 20 mins I'm starving. So I'd pretty much cut these foods out as well as gluten. Then I discovered I was starting to get a casein problem too (exactly like my gluten symptoms), and I cut out all dairy.
I read some stuff online about the Paleo diet and was like "Hey, that's what I eat!" I'd actually been joking to friends that I was on 'the caveman diet' after I had to cut out dairy (they were all saying "but what can you eat now??")
So, my curiousity piqued, I bought the Paleo Diet book a few weeks ago and read it straight through. It's basically the diet I had naturally ended up with after carefully listening to my body protest against all those other foods.
The book just laid out a good theory as to *why* my body was acting this way and, to me, it made a lot of sense. (In brief for those who don't know, the theory is that because our genetic makeup is only 0.02% different to what it was in the stone age, our bodies haven't had time to adapt to modern foods - grains, dairy, processed stuff, etc. I know for sure mine haven't!

... so if we eat more like our ancestors did, our bodies will be happier).
I eat more chicken eggs than our ancestor's probably would've though. If I can't have breakfast at home I'll have a banana for sure (I practically live on them if I'm in transit), but on the whole I try and go for berries, kiwis and pears because the more sugary fruits get me really craving sweet stuff and before I know it I'm buying boxes of gluten-free cookies I am breaking out and have gained 5lbs overnight

. I will have a teaspoon of local honey if I'm in the mood, and I certainly won't be cutting out my coffee!! I have it black with no sugar though (always did so no hardship

), and after 1 or 2 cups I switch to green tea (yerba mate these days).
The book basically showed me how to optimise the diet I had already naturally stumbled upon. I'm now cooking in flax oil (as well as olive oil), and trying to make sure I have a bigger variety of meat and fish. I'm also having salmon for breakfast with my eggs instead of sausages/bacon. For dinner I'll have either meat or fish with some veggies, and I stick either fresh herbs, ginger or garlic into most dinners which makes all the difference on the yum-o-meter.
Within a couple of days of eating this way I felt fantastic - just mega calm and happy. My body feels completely 'balanced' and I have a lot of energy. I'm not saying it's for everyone, but I think that if your body is pointing you in this direction anyway (as mine certainly was) it makes sense to give it a go. For me it's just a fine-tuned, more thoughtful version of the way I had started to eat anyway. There are now less glutenings as well (I've had zero since eating this way), probably because I'm eating whole natural foods so less chance of cross-contamination, etc. Not to mention way less preservatives, etc. All that's got to be a good thing. I miss dairy though and if I could eat it I would. There are some versions of the Paleo diet that permit dairy - I just gave it up because of the casein reaction. I still live in a house and drive a car that doesn't require my feet to stick through the floor though.
