Here is my impression.
We've got the standard paleo diet, which tends to be low carbohydrate. I assume most of us went on it for at least thirty days and it was good- definitely better than S.A.D.
Then we've got athletes. They find carbohydrates help them fuel their activities. They also have trouble relating to people who don't understand massive amounts of exercise and competitiveness. I am imagining these folks are like the folks who kicked Robb Wolf out of Crossfit. In other words, screw healing people, it is all about the competition.
We've also got academics. They hate the low carbohydrate message with a passion that makes them ignore those studies that prove ketogenic diets are good for various illnesses. Now, most of academia is not paleo, but if you are paleo and you want any sort of place in academia, it will soon seem perfectly reasonable for you to pretend carbohydrates have nothing to do with anything. There are many untruths it takes a relatively intelligent person to believe. This is why the proles, in general, don't believe in Marxism, but many academics do.
On the low carb side we've got a diet that works amazingly well, especially in conjunction with Paleo.
We've got reasonable people pointing out that the necessary research hasn't been done, but much like anyone trying to recreate climatology research, they are declared anathema.
Then, of course, low carbers can get nutty too. I did when I was losing weight, because any plateau caused a strong temptation to get really strict. Some folks who are less introverted than me have promulgated this sort of thing, but I doubt the sub 20g thing brings enough of a return to be worth it.
We've got people like Jack Kruse, who are bring new ideas up, and that is good. Please people, if you want to shoot him down, actually try to read his stuff! I'm seeing people I know are smart making silly mistakes because they are operating out of anger and not paying attention to what he said.
Let me return to the main point again- The standard paleo diet should be the 'best practice'. The one we tell people to try. Hold the potatos, rice, ice bags, piracetam, coprolites, intermittent fasting, high intensity workouts, and whatever else for 30 days so people can heal their guts. Suffer through the scandal of someone going into ketosis on occasion. Tell them to get rid of the grains, legumes, and dairy for thirty days and maybe grudgingly remember that avoiding carbs for awhile actually helps people comply.
So what is the state of the paleosphere? Pure anarchy, my friends, and that is pretty much awesome.
