Fat causes insulin resistance?

According to this blurb:

http://www.earthtimes.org/articles/show/2028.html

"In an experiment spanning four weeks, researchers kept hamsters on a diet
that had the fat levels resembling those in typical American fast food.
After being on the diet for four weeks, the hamsters developed insulin
resistance, a condition that indicates type 2 diabetes. At the same time,
another group of hamsters ate the same fat-rich diet but were also given
HPMC instead of the insoluble fiber that high fat food generally contains.
Unlike the hamsters in the first group, this group showed no signs of
insulin resistance."

Are they saying that a fat-rich diet causes insulin resistance? Moreover,
what "insoluble fiber" is there in eggs or meat? The reporter and/or
researchers really need to rethink this.

Not to mention insulin resistance does not "indicate[] type 2 diabetes."
There are plenty of folks with IR who are not diabetic.

I'd be careful about making any conclusions about this study. It was
presented and discussed at a meeting. It hasn't been published and/or
peer reviewed.

Since it has not been published we do not know many important things
about it. What types of fats are we talking about? What else was in the
diet? Was there a control group? Were the amounts of carbs in the diet
the same in types and amounts? etc. etc. Was it a properly planned
study or was it just thrown together?

Since so many "studies" are funded by industry sources, you really
cannot know if this is bona-fide research or if it is part of some
companies marketing.

Well, I personally don't place much stock in any study, regardless of who
pays for it. But you do bring up good points.

The writer's conclusions about the method of action of the soluble cellulose
is questionable. However, the reduced IR is probably a great benefit to the
rats.

They might be...but it seems that really an American fast food diet is what
is causing IR in these rats.

IR != T2 Diabetes.

I don't think I'd trust any of their conclusions.

Sophistry. (False Logic). This is another great example of a "study" that
is designed to slant the results by conveniently leaving out certain
factors.

First of all, the results are nothing new, it's been well-known for years
that a McDonald's type diet can cause insulin resistance. But of course,
there's a catch: You can eat that same high-fat Micky D's food and leave
off the bread and your metabolism goes back to normal. It's not the fat that
causes insulin resistance as they so desperately want to try to make us
believe, it's the freaking carbohydrates.

It's exactly like studying a group of old men wearing red sweaters and
teenage boys wearing blue sweaters, and coming to the conclusion that red
sweaters cause sickness and death. I can't abide these erudite morons who
take us all for idiots with their manipulative so-called data.

If they can do a real study that can show a high-fat diet *without the
presence of high carbohydrates* causes insulin resistance, then I may take
note. Otherwise, they don't need to do phony, slanted experiments with
hamsters: there are plenty of us who reduce insulin resistance and even
control our diabetes without medications on our high-fat, low-carbohydrate
diets. We already know the truth

That's not McDonalds then is it? You can't say you can eat at mcdondals
only eat completely different food. No bun. No fries. No McDonalds.

Correct, Peter. This is clearly very sloppy work that is based on a
preconceived notion and probably part of a down-the-road effort to flog some
new and worthless cellulose supplement that will cure all the diabetics.

Actually I have seen research in the past that has associated the amount of
fat in the diet with an increase in IR. But... these were not
carbohydrate-controlled diets. And as you say, it's no big secret that
SupersizeMe type diets are bad for the health in many ways. They are not
only high in fats, usually including a good portion of transfats, but alsoin
high glycemic carbohydrates and to top it off, lots of high fructose corn
syrup. This is a recipe for producing very high triglycerides, meaning there
is tons of fat in the blood. We all know that high triglycerides are closely
associated with insulin resistance. But which comes first? Is the high level
of fats in the blood (i.e., high triglycerides) damaging to the pancreas
and/or instrumental in reducing insulin sensitivity? Rather than the high
triglycerides being just a symptom of the IR?

Anyway, another thing we all know is that one of the first thing that
happens on a LC diet is that triglyceride levels tend to normalize, even
very high levels. Sometimes dramatically so. So even though you may be
eating a fair amount of fat, the amount of fat in your blood, in the form of
triglycerides, will tend to be lower... often significantly so... than if
you were eating a diet lower in fat but higher in carbs. Unfortunately this
never seems to be part of the equation in the experimental design, does it?
Meaning that most of this kind of research has dubious, at best, application
to people on reduced carb diets.

You missed the whole point which was to try to say that it's the fat in the
McDOnalds food that causes the insulin resistance -- which is not the case;
