Kurt Harris MD. His site is still up though he no longers posts, another advocate of just eat real food. Lastly, Chris Kresser feels that Paleo is merely a template for people to find their way.
Primal/Paleo is not for everyone, it's for those who have committed to understand.

and yes, calories DO count my little piggies
Jack Kruse, who has been putting out some interesting stuff lately, thinks cell-signalling and magnesium are intimately involved with this. What I did know is that diabetics urinate magnesium like there's no tomorrow - can't hold onto it. Someone posted a link to some newly published work on this, and he pretty much says: what did I tell you? See my gnolls.org post. I hadn't and it's quite interesting. Now he's not low-carb - although some people in paleo have tried to claim he is - but he says you have to watch the context and everything else that can bear on insulin-resistance (like sleep, for example). So he thinks the problem begins with insulin resistance but doesn't end there. Once that really takes hold magnesium goes and that causes damage to a particular area of the brain. Once thaat's happened, you have to eat low carb.

I kind of like this explanation. It could certainly explain why hunter-gatherers could eat a relatively high proportion of carbohydrate -- so long as it wasn't high glycemic load stuff and so long as everything else about their lifestyle was in order. At the same time. I think that probably would be true of, say, Bushmen.
At the same time It would explain why someone like Jimmy just could not.
I just had not known that diabetics urinated out Mg like mad.
