The idea seems to be that paleolithic diet was extremely high in fat and
proteins, compared to our modern diet of fat and carbohydrates.  Since
it is illogical to conclude that the people of this time could function
at a weight of 300 pounds or more, the conclusion seems to be that a
high fat/ protein diet is quite a bit healthier IN MODERN MAN than our
current high fat/ carb. diet and that we could get along quite well with
this diet.  My concern is that we aren't dealing with a level playing
field.  I understand that fat is an extremely efficient energy souce,
but the caloric requirements of paleolithic man must have been
fantastic.  I wonder what the affects of a high fat/ CARBOHYDRATE diet
would be on a modern human who walked perhaps 10-15 miles a day in
search of food and shelter.  Might the caloric expenditures be the real
variable we should be dealing with?  With that amount of exercise, it
would seem to me that it would take an exceptional amount of
carbohydrates to result in an unhealthy body.  And what of long term
side effects of a high fat/ protein diet?  Given paleolithic man was
lucky to live into their twenties, is it logical to extend that diet to
modern man who lives almost four times as long?  I do not question that
the Paleolithic diet was appropriate for Paleolithic man, but I am
hesitant to extend that diet to modern man without further understanding
of these other variables.  I am new to the list and appologize if this
has been covered in other discussions.

Cordially,
Kevin Tisdel
