message: In the entire treatment here, I can't find any reference to systemic inflammation or inflammatory signaling, which a lot of work suggests underpins IR - obesity causes upregulation of inflammatory signaling, as does lack of exercise, Western diet pattern, sleep deprivation, and Vit D deficiency - all factors in IR, metabolic syndrome and type II diabetes.

thread_title:  Intelligibility 

message: The one study that I've seen that promotes this hypothesis concerning olive oil is the one this article refers to.  There are many more studies that cite olive oil (and other monounsaturated fats)as neutral to good.  Additionally, the blanket statement that polyunsaturates (which include omega-6 and omega-3 oils) lessen/mitigate insulin resistance sidesteps the extreme difference in effects of the two on hormone production and inflammation.  In essence, the information on fats and insulin resistance appears both biased toward a limited amount of evidence for one hypothesis about monounsaturates(to the exclusion of the greater body of evidence), and a gross generalization that could lead people to believe that all polyunsaturated fats are equal (omega-3's are known to lessen inflammation, while most omega-6's are known for inflammatory properties). I've read that a quarter of the adult population has developed, or is at risk for developing some form of insulin resistance. That's a lot of people who could be coming here for guidance after the doctor has told them they are pre-diabetic, and they deserve better.
-Believe it or not, there are interesting individuals out there (Perricone fans?) who think that fish-based omega-3s reduce inflammation while plant-based omega-3s increase it.  I wish I knew where they were getting this.--Dseilhan 21:38, 20 March 2007 (UTC)
thread_title:  Monounsaturated Fat-Olive Oil leads to Insulin Resistance?  Polyunsaturated Fats All Good? 

message: The National Insulin Resistance Council (NIRC) appreciates both the technical complexity and the mystery of how insulin resistance starts and works.  While scientific research goes on, NIRC believes that there are enough dots to be connected into a pretty clear picture.  And the picture leads us to believe that there are specific things that can be done to improve it by a wide margin.
Consider this logic: 
No one doubts the links between insulin resistance (IR), diabetes and IR and CVD.  
Nor are the links between IR and PCOS and metabolic syndrome in question.  
Intervention with IR patients even when they have become symptomatic prolongs healthy life, and defers disease.
The villian in IR is hyperinsulinemia, having too much insulin too much of the time.  Insulin is suspect in liver signaling related to glycogen creation.  Insulin is caustic and erodes the inner linings of vascular tissue and the outer sheathing of certain nerve tissue.  These effects occur whether a patient is symptomatic or not.
IR appears to be genetically programmed, evidenced by the epidemiological data relating family diabetes and CVD histories.
IR certainly is aggravated by excess weight, and may be triggered by it.
If IR is the staging for consequential illness, and its effects occur unseen until symptoms like high blood pressure, elevated blood sugar or menstrual disruption show up, then why don't we seek to identify its presence early, before it does so much of its slow, relentless damage?
More logic, this part social:
There are 21+ million active diabetics in the US today and over 400 thousand fatal heart attacks not attributable to cholesterol.
Related sick care costs all taxpayers nearly 30% of Medicare expenses, all linked to IR. 
PCOS, caused by IR, is a significant cause of fertility issues, but the proportion is not known for lack of tracking.
In addition to the costs of active non-infectious disease care, who would guess at the cost of all the avoidable cases of PCOS, hypertension, gestational diabetes, diabetes, and CVD? The children and young adults of today with undetected IR are tomorrow's diabetics and CVD victims, yet they don't have to be.
Why aren't we scrambling to find ways to prevent non-infectious disease as hard as we scramble to deal with it?
NIRC proposes specific actions:
1.  Immediate efforts to find the easist, least costly, least intrusive, and most effective means to screen children and young adults for IR should be started and the best ones rolled out. 
2.  The CDC should track and report the incidence of IR.  Today, it does not even include IR in its index of conditions.
3.  The CDC should track and report the incidence of PCOS and especially the fertility complications from it.  
4.  The CDC should track and report the incidence of metabolic syndrome.  
Decades before the tobacco industry conceded that smoking caused cancer, warnings were put on their products.  Shouldn't people who have IR know it, so they can take action to blunt its effects before their lives have been shortened by it?  
The National Insulin Resistance Council's purpose is to educate health care professionals and the public about IR, its effects and to propogate workable interventions.

thread_title:  Connecting the Dots 

message: First, Wikipedia is not the place for starting social change, or making social commentary.  Wikipedia is a place for facts, and NIRC's comments above in "Connecting the Dots" are inappropriate.  Secondly, NIRC makes a verifiable claim, to wit: "Nevertheless, metformin, the 8th most often prescribed drug in the US, is often prescribed for pre-diabetes and insulin resistance, despite FDA instructions".  I am deleting this phrase, but anyone may feel free to re-add it should they be able to properly cite a reference for it.  Finally, the use of "NIRC ED" to distinguish edits made by NIRC is inappropriate.  The proper place to note the source of a fact is in a footnote to that effect, and anything that is not a fact, if it deserves to be in the article (e.g. connecting text), does not deserve to be especially distinguished from the rest of the article.

message: I added the reference about Wilhelm Falta who wrote about insulin resistance in 1931, 5 years before Harry Himsworth. Although much less known than Himsworth's paper (maybe because it is in German language and in a hard-to-find journal issue), Falta's paper has been quoted at least a dozen times in reviews on insulin resistance. However, I have not been able to find the paper itself, not even the abstract.  My guess is that there is not an available abstract and of course neither a DOI of the paper. Probably the only way to find the paper would be to look for a physical copy in some well-stocked medical library.
About Wilhelm Falta himself there seems to be no information available on the Web, besides the fact that he wrote the paper. A review by E. Gale in "Diabetes" states that he worked in Vienna, but doesn't say in which institution, nor describes his work.
The journal itself is quoted in all reviews as Klin Wochenschr, but it could possibly be the Wiener klinische Wochenschrift, as the Klinische Wochenschrift was edited in Berlin (it was the result of the union of the Berliner klinische Wochenschrift and the Therapeutische Halbmonatshefte in 1921).
Maybe somebody can find Falta's paper and/or add a little more background on Wilhelm Falta. I really would like to give a look at what this guy did. About the authors who quoted his paper in reviews, my guess is that most of them never saw it and are just passing the reference around. Tipically, Himsworth's experiments are described, but Falta is only mentioned.

message: New comment - not sure how to get the header (wiki-newbie)
I've edited the first few paragraphs of this article. There is some confusion within this article about whether it relates to insulin resistance as a concept, or the insulin resistance syndrome (or metabolic syndrome). In both cases, insulin resistance is associated with reduced insulin action, but only in the second case is it associated with dyslipidaemia, hypertension, etc. The causes of insulin resistance as a concept are many and varied, whereas the cause of the insulin resistance (metabolic) syndrome is obesity. My edits focus on the insulin resistance syndrome.
The other area of confusion was between insulin resistance and reduced insulin secretion. Any amount of insulin resistance will not cause high blood glucose concentrations as long as pancreatic beta cells cmpnsate by secreting proportionately more insulin. It is only if this compensation fails that impaired fasting glucose or impaired glucose tolerance occur. 
I'm a researcher in insulin resistance, but my study is all in dogs. Not sure if that makes me an expert for this purpose or not - dogs are one of the better models of obesity-induced insulin resistance. 
I hope this helps.

message: Signs and Symptoms #6's needs review: "Weight gain, fat storage, difficulty losing weight. For most people, too much weight is due to high amounts of fat storage. The fat in IR is generally stored in and around abdominal organs in both males and females. It is currently suspected that hormone production in that fat are a precipitating cause of insulin resistance"
The article thus indicates that adipose tissue gains volume, and thus turns into a hormone producer. (Minimally needs source, and probably needs full article link) What hormone specifically is being produced that causes insulin resistance?  There is a reference (#14 to a paper on growth hormone replacement therapy, but fat cells do not cause someone to undergo growth hormone replacement therapy). How does this tissue gain this ability to produce the hormone? 
Suggest deleting the 2nd-4th sentences, leaving just:
Weight gain, fat storage, difficulty losing weight.
Long thought of merely as depot storage for triglyceride, adipose tissue is now known to be an important endocrine tissue. Major active products are leptin, which is critical in the regulation of weight, adiponectin, IL-6, to name but a few. Ianmc (talk) 21:41, 30 April 2010 (UTC)

The entry can read something as basic as;
If body tissue is insulin sensntive, it easily and readily accepts nutrients from the body. If body tissue is insulin resistant, it does not accept nutrients as easily

message: Under the causes of insulin resistance is the following:
"Long term intake of highly fatty foods leads to the formation of fatty tissue that chronically release free fatty acids in the blood stream. This has been found in many studies to contribute to diminished insulin sensitivity. [11]"
which references the following article:
^ Schinner, S.; Scherbaum, W. A.; Bornstein, S. R.; Barthel, A. (2005). "Molecular mechanisms of insulin resistance". Diabetic Medicine 22 (6): 674. doi:10.1111/j.1464-5491.2005.01566.x. .
However, the only relevant section in the paper's abstract is this statement:
"Furthermore, we have now increasing evidence that the adipose tissue not only produces free fatty acids that contribute to insulin resistance, but also acts as a relevant endocrine organ producing mediators (adipokines) that can modulate insulin signalling."
The statement assumes that excess adipose tissue in humans is caused primarily by high fat foods. The reference makes no mention of this claim.
Please substantiate this claim or modify the original text.

Differential effects of palmitate and palmitoleate on insulin action and glucose utilization in rat L6 skeletal muscle cells.
Biochem J. 2006 Nov 1;399(3):473-81.
Abstract
An increase in circulating levels of specific NEFAs (non-esterified fatty acids) has been implicated in the pathogenesis of insulin resistance and impaired glucose disposal in skeletal muscle. In particular, elevation of SFAs (saturated fatty acids), such as palmitate, has been correlated with reduced insulin sensitivity, whereas an increase in certain MUFAs and PUFAs (mono- and poly-unsaturated fatty acids respectively) has been suggested to improve glycaemic control, although the underlying mechanisms remain unclear. In the present study, we compare the effects of palmitoleate (a MUFA) and palmitate (a SFA) on insulin action and glucose utilization in rat L6 skeletal muscle cells. Basal glucose uptake was enhanced approx. 2-fold following treatment of cells with palmitoleate. The MUFA-induced increase in glucose transport led to an associated rise in glucose oxidation and glycogen synthesis, which could not be attributed to activation of signalling proteins normally modulated by stimuli such as insulin, nutrients or cell stress. Moreover, although the MUFA-induced increase in glucose uptake was slow in onset, it was not dependent upon protein synthesis, but did, nevertheless, involve an increase in the plasma membrane abundance of GLUT1 and GLUT4. In contrast, palmitate caused a substantial reduction in insulin signalling and insulin-stimulated glucose transport, but was unable to antagonize the increase in transport elicited by palmitoleate. Our findings indicate that SFAs and MUFAs exert distinct effects upon insulin signalling and glucose uptake in L6 muscle cells and suggest that a diet enriched with MUFAs may facilitate uptake and utilization of glucose in normal and insulin-resistant skeletal muscle.

message: The article currently only discusses protease inhibitors used to treat HIV/AIDS as being one cause of insulin resistance. <anecdote>My significant other suffered from IR due to the medication she was on for epilepsy and depression. According to her the prescribing doctor informed her of the possibility of IR. She subsequently gained about 20kg within about a year (from ~64kg to 84kg). Unfortunately my partner is uncertain about whether the IR is due to only one particular drug or is caused by interaction between two or more of the handful of pills she took daily. At her most recent checkup a month ago her doctor changed almost all of her daily medication to eliminate the IR side effect (as well as the "over-stabilisation" of her emotions) - she has since lost about 5kg in spite of drastically reduced exercise due to knee surgery she had in the same week.</anecdote> From this story it is obvious that HIV/AIDS drugs are not the only pharmaceutical culprits. If someone knows something (and has MEDRS sources) about drugs other than protease inhibitors that cause IR please add the information to the article.
