Keith,

Thanks for your comments.  I am skeptical about the fat-burner/sugar-burner
dichotomy.  It just sounds a bit too unscientific for me.  Sure, the body
can run on different types of fuel, but I doubt it's a black-and-white
issue.  Faigan never really talks about a dividing line between the two, or
why it takes 7 days to "switch-over".  I would also hypthosize that their
are genetic differences as to carbohydrate preferences, though I don't have
any cites for this.

I think another problem may be the modern lifestyle.  In the winter in HG-
time, after the sun went down activity would naturally decrease.  In modern
times, many people stay active through the evening.  They also get much
less sleep than HGs.  So I think modern people may have more of a year-
round need for carbohydrates (for energy)due to the increased hours of
activity.
