Ok, that's what I was looking for.  Thanks Marilyn.

This is not a high fat diet.  High fat is 70-80% of calories.  This is moderate fat, high either carb- or glucose-producing-excess-protein diet.  Putting aside the still very controversial issue of saturated-fat-caused insulin resistance, because the diet these rats consumed would still be high in glucose, it's not a surprise that there was a degree of insulin resistance found.
