Thanks Judee. Interesting.

I have long doubted the relevance of rats to human nutrition. Rats
naturally have a very different diet than humans, though with a lot of
crossover as both are omnivores.

In regards to the result of this article and the paleo diet, if the
carbo amounts in your diet are consistently low then it really does
not matter what your insulin sensitivity is. You will rarely produce
enough insulin to cause trouble if you are getting most of your
calories from fat and the remainer from protein plus a bit from carbs.

turation of those fatty acids. When the amount of energy gained from
fat was greater than 37%, it was found that insulin sensitivity was
impaired in both the saturated fat group (-7.8%) and the
monounsaturated fat group (-3.3%). However, when the amount of energy
coming from fat was less than 37%, a significant difference was found
with saturated fat still decreasing insulin sensitivity (-12.5%) and
monounsaturated fat increasing it (+8.8%). Within the context of this
study, it would seem that insulin resistance can be improved
