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.
