I have been looking for a good research article that actually studies a gourp of people that have been low carb for a long term, maybe 2+ years.  All the studies I have found have been 1 year or less, and they usually say something about LC being good fro weight loss and lipid profile, but then there is a discalaimer that it is probably only temporary and there needs to be long term research.

In my reading I found this study http://www.eskiny.com/pdf/6.pdf.  Which is comparing a LC and LF diet.  The people were allowed to self limit calories.  Well, it turns out the LF people were averaging about 150 carbs a day.  Now that is not LC for sure, but it is a moderate carb diet and I would consider it crab restricted too.  The average 'dieter' eats about 300 carbs a day. 

I guess I feel like it is flawed research in that they did not allow the LF group to drink juice and do things that most people who eat LF do.  So it made their carb intake artifically low for the 12 week period of the study.  The typical 'healthy' diet is much higher in carb.

Anyway.  Just one of those things i found and got annoyed with

Well, the Inuit were low carb before meeting westerners.  Some more recent studies may not properly note that that has changed.

Just for the record, I did not state them as ideal, just as an example of low carb. Peoples with access to vegetation and fruits (virtually everyone not living in the poles) are likely moderate carb on average.

I agree with the study, however I think we are defining low carb differently. For me, low carb is less than 50g/day. Assuming a hunter-gatherer intake of 2,500 cals (could be more since they are hunting) and that 1g carbs = 4 cals, they only need 200 cals (less than 10% of their total intake) to be moderate carb in my book.

The study mentions that a lot of them get more than 85% of their calories from meat (both fat and protein). That would still mean that they would be getting ~ 375 cals from carbs which means ~ 90g carbs.

Groups living in more extreme conditions would probably get less carbs.

We have lived in many different parts of the world and are accustomed to all the different environments. Pick whatever carb consumption you feel best at, just make sure all your ingredients are paleo.

I agree that 150 carbs is not LOW carb, more moderate crab.  The problem with the study is that the average person that eats a low fat diet eats FAR more than 150 carbs a day.  So the study was not comparing a true low fat diet with a low crab diet.  It was comparing a low carb diet with a moderate crab diet, which is not the same.
