Don,

A while back I got into a row<<<civilised discussion on the  
runnersworld.co.uk website about paleo and running.  Needless to say  
stubborn ignorance prevailed, but I dug up some interesting facts  
trying to support my arguments.  (One of the runners was a test-tube  
fearing textbook-basher who refused to believe ANYTHING I said,  
regardless of how eye-gougingly obvious it was, without published,  
peer-reviewed scientific papers to support it.)

The one fact that stuck with me most is that in rats adapted to a  
high-fat diet, carbohydrate use was significantly better than in rats  
that ordinarily ate a high-carb diet.   I don't know if you can  
extrapolate that to humans, but if so it suggests that training for  
months at a time in deep ketosis and only eating significant carbs  
(dates sound good!) when competing could be a good strategy.

I found the link to the research at the bottom of this page: http:// 
www.nutritionandmetabolism.com/content/1/1/2 (see "Glycogen repletion  
and exercise endurance in rats adapted to a high fat diet").  I  
thought I'd post the page I found it on in case you see something  
else interesting there.
