The Track Your Plaque “Rule of 60”

The Track Your Plaque recommended targets for conventional lipids (i.e., LDL, HDL, triglycerides) are LDL 60 mg/dl, HDL 60 mg/dl, and triglycerides 60 mg/dl: 60-60-60.

Not only is this set of values easy to remember—60-60-60—but is grounded in science and the results of clinical trials.

LDL 60 mg/dl
The LDL target is based on experiences such as that of the Reversal Trial, the PROVE-IT Trial, and the Asteroid Trial, all of which showed that LDL cholesterol values in the range of 60 mg/dl dramatically enhance the likelihood of stopping plaque growth or achieving regression, reducing risk of heart attack more than more lenient LDL targets.


HDL 60 mg/dl
Achieving HDL cholesterol of 60 mg/dl is not as well grounded as LDL targets, mostly because increasing HDL is more difficult. There’s also no tremendously profitable way to raise HDL, as there is for reducing LDL (statin drugs). But epidemiologic observations strongly suggest that HDL of 60 mg/dl provides maximum control over both coronary plaque growth, as well as slashing rates of heart attack. Numerous smaller trials have borne this phenomenon out.


Triglycerides 60 mg/dl
Triglycerides of 60 mg/dl is based principally on studies that have shown a virtual elimination of abnormal lipoproteins, especially small LDL, when this value is achieved. Reduction of triglycerides is an effective means to reduce hidden lipoproteins like small LDL and VLDL. Triglycerides in the conventionally acceptable range of 100-150 mg/dl can be associated with dramatic abnormalities of lipoproteins.


Thus, the Track Your Plaque “Rule of 60”. In our day to day experience of trying to stamp out plaque growth from its terrifyingly rapid 30% per year, or reversing it—-dropping your heart scan score—-the Rule of 60 has held up time and again. Getting your lipids to 60 mg/dl does not guarantee that plaque growth stops, but it appears to be a necessary requirement that tips the scales heavily in your favor.

Those of you who’ve discussed lipid targets with your doctor will quickly recognize that the Track Your Plaque targets appear laughably ambitious, perhaps unnecessary. Recall that your doctor likely has no idea of what coronary plaque regression means. He/she likely conforms to the lax targets set by the National Cholesterol Education Panel (NCEP). (These targets depend on a number of factors such as whether you’re diabetic, sex, risk factors, etc.) Based on trial experiences like the few mentioned above, as well as my experience with purposeful coronary plaque reversal, the lipid guidelines as advocated by NCEP guarantee heart disease. Let me emphasize that again: Follow the guidelines set by the NCEP for your doctor to follow, and progression of heart disease is a virtual certainty. At best, it may slow growth of plaque and delay your heart attack or bypass surgery, but it will not stop it.

Now, that point made, let me make another: Just knowing about the targets and even becoming a member of the Track Your Plaque program does not mean that your lipids with automatically go to 60-60-60. We’ve actually had an occasional person tell us that they were disappointed that, by becoming Members, why hadn’t their lipids gone to 60-60-60?

Knowing that the 60-60-60 targets provide real advantage is not the same as actually achieving them.

A little bit of fish oil


The British National Health Service (NHS) has announced that, in light of the substantial data documenting that omega-3 fatty acid intake from fish reduces likelihood of cardiovascular events by around 40%, that Brits discharged from hospital following a heart attack should be "prescribed" 1000 mg of prescription fish oil per day.

Hardly a revolutionary concept. Part of the timidity of the British NHS seems to relate to the potential cost to the government, since apparently much of the cost will be borne by the government-subsidized health system.

But prescription fish oil? Why prescription fish oil? Prescription Omacor, one capsule per day, costs around $70 (U.S.) per month. If I go to Sam's Club the same quantity of omega-3 fatty acids (in three capsules) will cost around $2.50. That's less than 5% of the cost of the prescription form.

Omacor is clearly more concentrated. But is the prescription form better--more effective, more purified, less contaminated, etc.? I have seen no independent verification of this. Of course, manufacturers make all sorts of claims. The only independent, unbiased testing I'm aware of comes from organizations like Consumer Reports and www.consumerlabs.com. Omacor has not been compared to non-prescription fish oil in any of their analyses. Head-to-head comparison of Omacor to nutritional supplement fish oil is unlikely to come from Solvay, the manufacturer of Omacor. Drug companies powerfully resist head-to-head comparisons, fearing it will not play out in their favor. Let the public remain ignorant and hope marketing conquers all.

Why would the NHS only recommend eating fish and prescription fish oil? I don't know, but it smells awfully fishy to me. As soon as an opportunity for profit is built into a treatment, all of a sudden it gains endorsement. Perhaps lobbying by those parties with potential for profit drove the process.

Nonetheless, despite the filthy politics and under-the-table dealings, some good comes out of the NHS's action: broader recognition of the power of fish oil. Perhaps when a British patient or an American patient gets discharged with a prescription for Omacor, the patient will take the initiative and go to the health food store instead and save him (or his insurer) $67.50 per month.

For your coronary plaque control program and control and/or reversal of your heart scan score, we start at 4000 mg per day of standard fish oil, providing 1200 mg per day of omega-3 oils. This amount as a nutritional supplement costs only a few dollars a month. And you have the satisfaction of not only taking a powerful step for your health, but also not enriching the overflowing pockets of drug companies.

AHA: Doctors don't have time for prevention

Doctors "don't have enough time to educate their patients and to stop and think about what measures the patient really needs," says Dr. Raymond Gibbons, new head of the American Heart Association.

Dr. Gibbons highlighted how the system reimburses generously for performing procedures, but reimburses relatively little (often just a few dollars) for providing preventive counseling. He claims to have several ideas for solutions.

Good for Dr. Gibbons. There's no doubt that the lack of truly effective preventive information and counseling is a systemic, built-in flaw in the current medical environment. It is especially true in heart disease.

Another problem: "If a doctor didn't say it, it must not be true." That's the attitude of many of my colleagues. Despite their broad and systematic failure to provide preventive counseling, most physicians (my colleagues the cardiologists especially) pooh-pooh information that comes from other sources. Yet, it's my prediction that much of healthcare will go the way of optometry--direct access to care, often delivered in non-healthcare settings like a store or mall. People are hungry for truly self-empowering health information. Too many physicians can't or won't provide it. You've got to turn elsewhere for it.

That's one of the main reasons I set up the Track Your Plaque program. It's direct access to self-empowering information. A flaw: You still require the assistance of a physician to obtain lab values, lipoproteins, and to monitor certain treatments (e.g., niacin at higher doses). If I knew of a way around this, I'd tell you. But right now I don't. We remain constrained by legal and moral obligations.

Nonetheless, phenomena like CT heart scanning and the Track Your Plaque program are just a taste of things to come.

Confusion about Lp(a)

Since the recent reader question about Lp(a), I've had several other instances of confusion over Lp(a).

To help you navigate through some of the often confusing issues behind this complex genetic abnormality, here are some common sense rules to follow. When you ask your doctor to draw a Lp(a), try to be certain that:

--the same laboratory is always used. Just going from lab to lab can account for huge variation in Lp(a). As standardization proceeds internationally, this will be become less important. But in 2006, it's still an issue.

--you and your doctor resist the temptation to check Lp(a) frequently. I saw a patient recently who was having Lp(a) levels nearly every month. This is pointless. Lp(a) changes very slowly. Checking it frequently will not allow any treatment to be fully reflected. All you'll observe is random variation that can be frustrating. We wait at least 6 months before re-checking after a new treatment is introduced.

If you have a choice, I would recommend you opt for the measure provided by Liposcience (NMR). The technique they use is a particle count measure, rather than a weight-based measure. This may be more accurate, particularly when Lp(a) is small.

Lp(a) remains among the more difficult patterns to understand and correct. Don't be surprised if you encounter a lot of confusion from your doctor, as well. You may end up providing much of his/her education.

Calculus of the cardiologist

I call this the "calculus of the cardiologist":

Heart procedures = big money

More procedures = more big money

You do the math. If you do more procedures, you get more money.
What if your patients don't need more procedures? That's easy. You lower the bar on reasons to do procedures. You scare the pants off people and lead them to think that all heart disease or questions about heart disease are potentially life-threatening. You could even appear to be doing the patient a big favor. "My Lord! This is potentially dangerous. We need to perform a procedure without delay!"

There are incentives beyond direct cash payment. A patient of mine today showed me a memo to employees in his company that showed why certain hospitals are targeted for care. The criteria for choosing centers was based on number of procedures performed. In other words, the more procedures performed at a hospital, the more procedures will be directed there. Of course, this makes sense at some level. More procedures can also mean greater skill.

But have we lost sight of the fact that the mission is not more procedures and more money, but to get rid of a disease? If the intensity of effort devoted to heart procedures were re-directed to early detection, prevention, and reversal of disease, we'd have half the hospitals we now have. We'd also chop a huge chunk out of the national healthcare budget.

Lipoprotein(a) treatment alternatives

A question from a reader:


Two years ago, my doctor recommended a comprehensive lipid screening because both of my parents had heart disease. My only blood component way out of line was LP (a) [lipoprotein(a)]. It was 130. According to the lab that conducted the screening, Berkeley Heart Lab, a level above 30 should be cause for concern. I was stunned that mine was more than quadruple the danger level.

I began taking two grams [2000 mg] of niacin a day in addition to the Lipitor I was already taking. The next reading, a few months later, was 87. Over a period of about 18 months, I had a total of four readings from Berkley Heart Lab. My LP (a) fluctuated in the 80-130 range – still way above normal. My doctor said there was little else I could do to control it.

That doctor has since retired. I now see another doctor who uses a different lab. My first LP (a) reading with him a few months ago was 17, which is normal. I am still taking the same amount of niacin and Lipitor and I can’t think of anything that would account for the huge discrepancy. I’m going to have another test again soon.

Is one of the labs giving erroneous readings? If so, how can I tell which? If Berkeley Heart Lab is correct, is there anything I can do about my increased coronary risk due to high LP (a)?

Tom D.

Tom's frustration on the variation of Lp(a) is due to the fact that laboratories run the Lp(a) test by several different techniques and will generate tremendous variation in values. The key is to stick to the same measure over and over from the same lab, else you'll be terribly confused and frustrated. Tom essentially should ignore the value obtained that was unexpectedly low.

Another issue: Lp(a) is a turtle. It responds very slowly. In fact, we rarely check it more than once or twice a year. Check it too soon after a treatment change and it won't fully reflect the effect. You've got to wait at least several months before re-checking.

How about treatment alternatives? They are:

--More niacin. Not my favorite choice, since niacin >2000 mg per day begins to generate more side-effects, but it is a choice. You can go to 4000-5000 per day, but only with your doctor's supervision due to liver effects.

--Testosterone for males. We use topical testosterone from Women's International Pharmacy in Madison, Wisconson. Prescription patches like Testim are also effective.

--Estrogen for females. This is less "clean" than testosterone, introducing questions about endometrial and breast cancer risk, but it is a choice.

--DHEA--A small effect but every little bit can help. We use 25-50 mg per day, depending on blood levels and only if you're 45 years old or older.

--l-carnitine--In my experience, a small effect. It requires 2000 mg per day, which is expensive. Sometimes, an expected large effect develops, so it's worth a try if it fits in your budget.

--Fibrates--These are the drugs Tricor and Lopid. I don't like these agents very much because I think they're weak, including the effect on Lp(a) reduction. But they are choices for you and your doctor.

Lastly, you can simply be guided by your heart scan score. For example, if Tom's initial heart scan score is 200, and he continues his current program and one year later his score is 300, then alternative treatments are worth considering. But what if Tom's score is 189--he's regressed his coronary plaque. Then, who cares what his Lp(a) is?

Another issue to keep in mind is that, in the presence of Lp(a), keeping LDL to very low numbers (e.g., 60 mg/dl) may added value in preventing coronary plaque growth.

Trapped in a low-fat world

If you would like to...

--Reduce (good) HDL

--Raise triglycerides, sometimes by hundreds of points

--Raise blood sugar into the pre-diabetic range

--Raise blood pressure

--Accelerate coronary plaque growth

then go on a low-fat diet like the one promoted by long-time super low-fat advocate, Dr. Dean Ornish. Every day I have to educate patients that a low-fat diet as advocated by Dr. Ornish is a destructive, counter-productive process that makes coronary plaque grow and increases your heart scan score.

If you want to gain control over coronary plaque, do not follow the Ornish program or anything resembling it. The Ornish program is a dead end.

Instead, the crucial components of a healthy diet for plaque control are:

--Low saturated and hydrogenated fat, but not low all fats.

--High monounsaturated and omega-3 fats

--Low glycemic index (i.e., slow sugar release)

--High fiber

That simple. An excellent program to put these limits to practical use is the South Beach Diet. Or, follow the more detailed guidelines on the Track Your Plaque website (open content section).

Blame the niacin

Despite the fact that niacin is:

1) A vitamin--vitamin B3

2) One of the oldest cholesterol-reducing agents around with a long-standing track record of effectiveness and safety

3) Available as a prescription drug as well as a variety of "nutritional supplements"

most physicians remains shockingly unaware of its benefits, effects, and side-effects. Most, in fact, are either ignorant or frightened of advising their patients on niacin use. As a result, I commonly have to tell my patients to resume the niacin that their primary care physician has (wrongly) stopped because of itchy feet, grumpiness, groin rash, urinary tract infections, nightmares, diarrhea, hair loss, runny nose, etc. All of these are REAL reasons doctors have advised patients to stop niacin (though none were actually due to niacin).

Is niacin really that troublesome? No, it's not. In fact, if used properly, it's among the most effective and safe tools available for correction of low HDL, small LDL and other triglyceride-containing lipoproteins, lipoprotein(a), and dramatic reduction of heart attack risk. If added to a statin agent, the heart attack risk reduction can approach 90%.

Statins are just too easy for doctors to prescribe. Niacin, on the other hand, requires a good 15-20 minutes to describe how to use it. It could generate an occasional phone call from a patient who struggles with the annoying but largely harmless and temporary "hot-flush" feeling, a lot like a hot blush. Given a choice, most doctors would simply choose not to be bothered. For this reason, I'll commonly see many, many people with uncorrected low HDLs and other patterns.

Have a serious discussion and press for confident answers if you find your doctor reflexively telling you that the wart on your thumb should be blamed on niacin.

Here are the steps we advise that really make taking niacin easy and tolerable:

1) Take with dinner.

2) Take with 2 extra glasses of water. If you experience the hot-flush later on, drink an additional 2 8-12 oz glasses of water i.e., a total of 16-24 oz). Extra hydration is extremely effective for blocking the hot-flush.

3) Take a 325 mg, uncoated aspirin. This is only necessary in the beginning or with any increase in dose, rarely chronically for any length of time.


This is not to say that there aren't occasional people who are truly and genuinely intolerant to niacin. It does happen. But those people are a small minority, less than 5% of people in my experience. Niacin is far more effective and safe than most physicians would have you believe.

Eat fish three times a day

Patients commonly ask, "Why can't I get vitamin D from food? I drink milk and eat fish."

They're absolutely right: both vitamin D and some oily fish contain vitamin D. However, it's a matter of quantity. An 8 oz. glass of milk contains 100 units of vitamin D (at least it's supposed to; this is not always true). A serving of oily fish like salmon or herring may contain up to 400 units. Thus, if you ate fish three times a day like the Eskimos or the Inuit, you might obtain sufficient vitamin D to prevent the broad and alarming spectrum of phenomena associated with deficiency.

I suspect that most people don't want to eat fish three times a day, nor drink the 20 to 50 glasses of milk per day that would be required to obtain a truly healthy quantity of vitamin D.

The vocal and outspoken Dr. John Cannell of the Vitamin D Council (www.vitamindcouncil.com) has written eloquently on the potential relationship between influenza and vitamin D deficiency. He and his co-authors on a recently published paper point out that the peculiar and unexplained seasonality of influenza corresponds to vitamin D levels. Read his eloquent discussion in Medical News Today at http://www.medicalnewstoday.com/medicalnews.php?newsid=51913.

In the article, Dr. Cannell explains:

"The vitamin D steroid hormone system has always had its origins in the skin, not in the mouth. Until quite recently, when dermatologists and governments began warning us about the dangers of sunlight, humans made enormous quantities of vitamin D where humans have always made it, where naked skin meets the ultraviolet B radiation of sunlight.
We just cannot get adequate amounts of vitamin D from our diet. If we don't expose ourselves to ultraviolet light, we must get vitamin D from dietary supplements...Today, most humans only make about a thousand units of vitamin D a day from sun exposure; many people, such as the elderly or African Americans, make much less than that. How much did humans normally make? A single, twenty-minute, full body exposure to summer sun will trigger the delivery of 20,000 units of vitamin D into the circulation of most people within 48 hours. Twenty thousand units, that's the single most important fact about vitamin D. Compare that to the 100 units you get from a glass of milk, or the several hundred daily units the U.S. government recommend as “Adequate Intake.” It's what we call an “order of magnitude” difference.

"Humans evolved naked in sub-equatorial Africa, where the sun shines directly overhead much of the year and where our species must have obtained tens of thousands of units of vitamin D every day, in spite of our skin developing heavy melanin concentrations (racial pigmentation) for protecting the deeper layers of the skin. Even after humans migrated to temperate latitudes, where our skin rapidly lightened to allow for more rapid vitamin D production, humans worked outdoors. However, in the last three hundred years, we began to work indoors; in the last one hundred years, we began to travel inside cars; in the last several decades, we began to lather on sunblock and consciously avoid sunlight. All of these things lower vitamin D blood levels. The inescapable conclusion is that vitamin D levels in modern humans are not just low - they are aberrantly low."


Like Dr. Cannell, I am absolutely convinced that vitamin D deficiency plays an important role in a number of illnesses, including coronary disease. The more we mind our patients/participants vitamin D status (blood levels of 25-OH-vitamin D3), the more easily we gain control over LDL cholesterol, pre-diabetic patterns, blood pressure, blood sugar, and coronary plaque. In fact, I am becoming rapidly convinced that vitamin D deficiency is an extremely important coronary risk factor.

Because I live in Wisconsin (bbrrrrr!) where seeing the sun is a cause for celebration and sun exposure is possible three months a year, I take 6000 units per day vitamin D. This is the amount necessary to raise my blood levels into the true, physiologic range of 50-70 ng/ml. My wife takes 2000 units per day, and each of my kids takes 1000 units per day, though I believe that my 14-year old son (my size now) should take more. We'll judge by blood levels.

If there is a little-known secret to reducing heart scan scores, vitamin D is that "secret".

What if I had a cure for coronary disease?

If I had a cure for coronary disease, what would it look like? What would constitute cure? Would you recognize it if I showed it to you?

In the strictest sense, "cure" means an absolute elimination of any sign of coronary plaque, as well as elimination of any and all dangers associated with coronary disease. It would also mean elimination of the factors that created coronary atherosclerotic plaque in the first place.

In a more practical sense, you could argue that "cure" means a reduction of the amount of material that constitute coronary disease along with a dramatic reduction of the associated risks (i.e., heart attack).

You might call this second, more lax definition "regression" or "reversal".

Is "cure" in the strictest sense possible? No, not to my knowledge in 2006. Yes, there are many (kooks) who claim this is possible, but there's no objective evidence of this occurring.

Regression, or reversal, however, is indeed possible. In fact, I've seen it countless times following the participants in the Track Your Plaque program. If your heart scan score goes from 1000 (a bad score with high risk for heart attack) to 750, you've experienced a large reduction in the amount of atherosclerotic plaque that is behind coronary disease. You've also reduced your risk of an "event" like heart attack to near zero (provided you remain on the program that achieved regression in the first place).

Unfortunately, with present technology regression or reversal does not mean that the original causes of coornary plaque are eliminated. They're just controlled. Fish oil, for example, powerfully reduces triglyceride-containing lipoproteins that trigger coronary plaque growth. But if you stop fish oil, the evil lipoproteins come right back and start injuring your coronaries, causing more plaque growth.

The Track Your Plaque program is the closest thing I know of to a "cure" for coronary disease, that is, "cure" in the sense of regression or reversal. Perhaps in future we'll have a "cure" in the strict sense. Until now, this program is the best there is.
Small LDL particles and increased HbA1c--An evil duo

Small LDL particles and increased HbA1c--An evil duo

Small LDL particles are triggered by consumption of carbohydrates. Eat more "healthy whole grains," for instance, and small LDL particles skyrocket.

Increased hemoglobin A1c, HbA1c, a reflection of the last 60-90 days' blood sugars, is likewise a reflection of carbohydrate consumption. The greater the carbohydrate consumption and/or carbohydrate intolerance, the greater the HbA1c. Most regard a HbA1c of 6.5% or greater diabetes; values of 5.7-6.4% pre-diabetes. However, note that any value of 5.0% or more signifies that the process of glycation is occurring at a faster than normal rate. Recall that endogenous glycation, i.e., glucose modification of proteins, ensues whenever blood sugars increase over the normal range of 90 mg/dl (equivalent to HbA1c of 4.7-5.0%). Glycation is the fundamental process that leads to cataracts, arthritis, and atherosclerosis.

Put the two together--increased quantity of small LDL particles along with HbA1c of 5.0% or higher--and you have a powerful formula for heart disease and coronary plaque growth. This is because small LDL particles are not just smaller; they also have a unique conformation that exposes a (lysine residue-bearing) portion of the apoprotein B molecule contained within that makes small LDL particles uniquely glycation-prone. Compared to large LDL particles, small LDL particles are 8-fold more prone to glycation.

So glycated small LDL particles are present when HbA1c is increased above 5.0%. Small, glycated LDL particles are poorly recognized by the liver receptor that ordinarily picks up and disposes LDL particles, unlike large LDL particles, meaning small LDL particles "live" much longer in the bloodstream, providing more opportunityt to do its evil handiwork. Curiously, small LDL particles are avidly taken up by inflammatory white blood cells that can live in the walls of arteries, where they are oxidized--"glycoxidized"--and add to coronary atherosclerotic plaque.

The key is therefore to tackle both small LDL particles and HbA1c.

    What do you consider to be ideal cholesterol readings? I am about to visit a new doctor, a D.O., and I am sure she is going to insist on blood tests for cholesterol plus stress testing, etc. My thyroid TSH was 2.70, but she is already showing reluctance to prescribe any thyroid meds. It is going to be a battle.

    And it is not just about the wheat either.  It’s all carbs.  Fructose, oats, rice, pasta, potatoes and certain fruits, etc. all drive up HbA1c and small LDL.  Just for a reality check I bought a can of and made a bowl of “properly prepared” Scottish oatmeal yesterday according to Nourishing Traditions.  Those are the minimally processed chewy steel cut oats soaked with warm water and kefir overnight and served with butter and cream.  Yeah, they were good alright, but my fasting BG was 88 and one-hour PP was 158.  A fast 5-mile run and it was back down to 84.  The container is in the garbage can now.  This morning was two pasture raised eggs and bacon with ½ cup of blueberries and Greek yogurt.  Fasting BG 89 and one-hour PP was 88.  My HbA1c went from 5.8 to 5.1 in less than a year and hope to get below 5.0 soon.  The stubborn small LDL percentage dropped during same time period but still have a way to go in that regard.

    I'm not completely sold on HbA1C < 6.0% being a useful metric for anything but populations.  The problem is that the current HbA1C tests do not control for erythrocyte age and I see wide variations among piers on simialr  grain free lowish carb healthy diets.

    There has been much more research on this effect as it pertains to diabetics that have falsely low HbA1c:  http://www.ncbi.nlm.nih.gov/pubmed/9773739
    http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2581997/

    There is some evidence out there that it works the other way as well, and it makes intuitive sense that the lower inflammation and oxidation associated  with a healthy diet would increase erythrocyte longevity.

    Of course observational studies about any topic (small LDL or HbA1c) are always to be taken with a grain of salt.

    I wonder if you have ever experienced with any of you patients  what is going on with my husband?  He has very few small LDL particles, at least according to a VAP test - he is type A with lots of large, fluffy LDL.  But his HbA1c is 6.1.  His fasting glucose is 80, 1 hour post-prandial it's 1685, triglycerides are 60.  This is all on a grain-free, very low-carb Paleo diet.  Do you have any clue what is causing the HbA1c to be elevated?  Could it be anything besides carbs?  He gets lots of exercise and is very fit and lean.  

    Some have suggested that too much protein can also cause elevated HbA1c, due to gluconeogenisis causing higher levels of glucose.  But why would the body make more glucose than it needs?  And why would that excess glucose not show up in his fasting and post-prandial glucose numbers?

    Is there any other factor, besides blood glucose, that can contribute to elevated HbA1c?  No doctor yet has been able to answer this question for us.

  • Rosanne

    10/30/2011 8:32:55 PM |

    Sorry for the typo, his 1 hour post-prandial glucose is 85.

  • Dr. William Davis

    10/30/2011 9:08:02 PM |

    The most common explanation, Rosanne, is that the HbA1c can stay high long after blood sugars have come under control.

    It may be due to the extended longevity of RBCs that occurs in the setting of low-carbohydrate diets that allow a previously high HbA1c to stay high for an extended period.

    There's also the possibility of a hemoglobin variant that allows this.

    I would put more stock in the blood glucose values by fingerstick than the HbA1c.

    Your article discuses how the combination of small LDL particles  and high blood sugar
    results in plaque. Is the article cited below  by University of Washington at St. Louis useful here? The article points out the role of low Vitamin D in plaque formation with LDL  and high blood sugar. Or am I confusing two separate mechanisms in plaque formation.

    HI Doctor Davis,

    I read "wheat belly", it was revolutionary for me,  and I am persuaded it can bring much relieve to many ailments.

    I also wrote several posts about this issue on my health blog (in Hebrew)  based on your book and your Blog.

    Hello Dr. Davis,
    I'm new to your blog. Just finished reading Wheat Belly. Excellent book! I also listened to the podcast with Robb Wolf. That's how I heard about you. Not to get off topic (didn't know how else to contact you) and this is probably a silly question, but would like clarification if you could help. I've been purchasing the 85% Lindt chocolate bars until you mentioned that you eat the 90%. I read the label and it said that it is pressed with alkali. You mentioned to avoid this process as it removes the healthful flavonoids. By saying "pressed" is that a different process? The chocolate was very good, but I want to make sure I'm getting the healthful flavonoids, especially when we don't eat too many sweets. Thank you so much for your time.

    Hi Dr.,
    I am confused how to  reconcile  HbA1c details  from J Am Coll Nutrition 2005, Vol.24(1):22-29
    "Dietary Carbohydrate and Glycated Protein in the Blood in Non-Diabetic Subjects"
    http://www.jacn.org/content/24/1/22.full
    (and their relevant references no. 10 -  19 & 34-39 )

    This has been going on for 2 1/2 years and in fact, the longer he has been low-carb Paleo, the higher the HbA1c has gotten.  When he started, it was 5.5 and has slowly
    crept up to the 6.1 reading.
    Thanks for the mention of the hemoglobin variant, I guess that's must be it.  Can we stop worrying about the HbA1c since his glucose values are so good?

    Dr. Davis:
    What do you you think of Jenny Ruhl's advocacy of the 5% club at Blood Sugar 101? Your guidelines appear to be more aligned with Dr. Bernstein's and Dr. Ron Rosedale's? Do you think that all individuals ( including prediabetics, daibetics and glucose intolerant ) should strive for a HbA1c below 5%?

  • Dr. William Davis

    11/2/2011 1:36:45 AM |

    HI, STG--

    That is precisely what I aim for, also: HbA1c of 5.0% or less. At that level, metabolic consequences of blood sugar essentially disappear. This is, of course, at variance with conventional guidelines.

  • Dr. William Davis

    11/2/2011 1:37:19 AM |

    That would be my vote. Ask your doctor, also, about fructosamine, another sugar markers.

    My bar says "processed" so, yes, the flavonoid content can be expected to be reduced in this bar. The best way to get a full dose of cocoa flavonoids is in undutched cocoa powder.

    Hi Dr. D.,
    Authors in this report say glycated protein & HbA1c do not interact  with blood glucose in same way (ref #17) and that it is glycated albumen rather than glycated hemoglobin that is very senstitve to blood glucose levels (ref # 18,19); especially since 60% HgA1c is genetic (ref #61).
    AGE (advance glycation endproducts) they say is more indicated by fructosamine level from high blood glucose. Although diabetics with high fructosamine also have high HbA1c. whereas for a non-diabetic  high fructosamine does not relate to their HbA1c level (ref#16).
    This impies that (since most obese individuals never will become diabetic &  longevity/cognitive function of the overweight is good) a lot of the risk factor of small LDL with HbA1c depends on genetics/ epigenetics.
    My confusion is if your insistence on HbA1c for non-diabetics is misdirected or just due to it being a common first test people can do.

    Wheat is the most common carbohydrate in Israel. It is eaten almost every meal. I think that the largest source of calories is wheat.

    Regarding Diabetes there is no awareness that whole wheat is especially bad for such patients. Diabetes association (and many more) do recommend whole wheat. Although they are suggesting to avoid eating large quantity of bread at once.

    Wheat is being pushed, though, I don't think that somebody here is pushing wheat deliberately, just coping recommendation from abroad, and using the most cheap and easy carbohydrate.

    I have been on my Wheat Bellies journey for 8  weeks now.  I am trying to follow your suggestions on heart health and I know that you have your plate full right now, but just a request.  Have you ever thought of doing healthy heart retreats?  I would love to have a chance to go away for a long weekend, have all my blood work done right, have it evaluated, talk to a doctor and then maybe have a few cooking classes.  Throw in a few yoga classes or walks for stress reduction and you have a whole picture!!  

    I have high blood pressure that is 'controlled' to some degree with Tekturna (150mg) and Amlodipine (10mg). This morning it was 150/90, so it is often not very controlled. Since 9/1 and going wheat free, I have lost 23 pounds but still have 50 to lose.  My take away from your writings is that plaque is the  main cause of heart disease and that keeping a low blood glucose level is the best strategy, but there is not much about  high blood pressure in your work.  What role does it play and will being a wheat free low carber offer me relief from my high blood pressure?  Or will it stay high since I have a family history of high blood pressure and therefore will probably have to continue on my meds.  While I, of course, am doing everything in my power to lower my blood pressure, is it not really a number I should focus on when trying to control my heart health?

    Hi, Nora--

    Excellent suggestion on the heart health retreats. I've thought a lot about it and will likely do it in future. Just not quite sure about the details. One hurdle: Few people want to fly to Milwaukee, so we'd have to find an exotic or interesting, probably warm, place to do it.

    Hypertension is indeed a big issue. It is also among the last things to respond to weight loss and diet, often lagging behind many months after weight loss. So it really pays to be patient while you are on this health journey. Given your family history, you still might be left with hypertension, but at least you will have minimized it.

    Hmmm. I'm sorry if I'm being dense, Might, but I'm still not sure I follow.

    I'm not actually advocating anything except to show how glycated small LDL is a really bad player. When viewed from multiple different directions, small LDL particles are looking worse and worse. In this instance, having any measure of glycation phenomena, whether fructosamine, glycated albumin, or glycated hemoglobin, suggests that small LDL particles are also being glycated and thereby gaining heightened atherogenic potential.

    I am reading your book Wheat Belly and want to thank you so much for writing this book.

    I've avoided gluten for years.  Arthritis and other annoying symptoms vanished...but I started gaining weight!   My blood sugar starting rising!   I couldn't understand it!  It was horrifying!  Well thanks to you, I realize that gluten free breads, candies, flours,  frozen pizzas, pastas and those gluten free "tv dinners" sold at Whole Foods did nothing to help my waist line or blood sugar.  I am now following the wonderfully easy plan in your book and am confident the weight will come off.

    Thank you for such terrific recipes.  Will you be writing an accompanying Wheat Belly cookbook as well?  I certainly hope so.  Please do!   If not, can you recommend some cookbooks that comply with your eating instructions?

    Thanks again for such a life changing book.  Sally

    There are a few people in Israel trying to enlighten others about the dangers of wheat and other 'modern' carbs.  My sister is one of them, has been trying to think of ways to get some essays to the public.  But what Amit says is correct - a lot of wheat is eaten there, many people buy small breads  rolls daily - it's very fresh, delicious, so it will be a tough thing to stop. Many of the best restaurants in Israel serve Arabic food which always comes with freshly baked loaves of pita.  The 'national snack' is pita stuffed with falafel (fried balls of ground chickpeas, onions, garlic and spices), fresh & pickled vegetablesj, hummus and/or tehina sauce. This is available everywhere and always fresh.  Becasue the food is generally very good in Israel and also very fresh it's hard to avoid wheat, which I've noticed every time I visit.

    Dr. Davis, the evidence speaks for itself that consumption of carbohydrates, increase small LDL, suggesting an LC diet of less than 50 grams to mitigate the damage.
    But what about endurance athletes (runners, cyclists, triathletes etc.) that work out one and a half to three hours per day and consume copious amounts of carbohydrate to fuel their long workouts.
    Is the exercise neutralizing the carbohydrates' harmful effects? If so, can you suggest a dosage for certain amount of exercise?

    11/6/2011 8:26:57 PM |

    Hi Dr. Davis,
    Non-diabetics just seem to have one feature going for them - their platelets don't respond the same as diabetics. I am inclined to think that albumin in our blood is more relevant than the hemoglobin being glycated . (This is not to criticize your preventative approach , since Type II diabetes can go on to develop &  I like what you are teaching us about small LDL.)

    " One common qualitative change in plasma albumin is nonenzymatic glycosylation, which occurs during states of prolonged hyperglycemia....Platelet aggregation ...is enhanced in the presence of albumin that has been incubated in a medium containing levels of glucose that are higher than would be seen in normal patients but are consistent with those seen in diabetics....(Journal of Parenteral and Enteral Nutrition 18:516-520, 1994)

    Once the glycation of albumin fosters more platelet aggregation in diabetics (& the insulin resistant person!) their platelets show more secretion and adhesion leading to the vascular plaque build up that the insidious small LDL can get into. Yet, for the non-diabetic the +/- 570 insulin receptors on each platelet normally respond differently to their insulin exposure.

    Specifically (in non-diabetics) the insulin actually stymies the platelet from becoming "activated" and probably explains how it is that not everyone who eats carbohydrates suffers cardio-vascular insults. Of course there are non-diabetics with genetic variants that adversely affect their plaque dynamics (ex: defect in insulin receptor signalling, that receptor's Beta subunit, G-protein pathways).

    ( For the techno-nerds: proper insulin receptor response on platelet keeps  platelet cAMP level from dropping & so no endoplasmic reticulum calcium floods out into platelet cell cytosol, platelet granule doesn't secrete ATP, platelet alpha-granule doesn't secrete P-selectin & there isn't mitogen-activated signalling to make thromboxane A2 , etc.  Basically, in the diabetic/insulin resistant these processes go forward uninhibited by normal insulin signalling & their circulating platelets don't keep rolling along suspended in the bloodstream .)

    Omega 3 Fish Oil BAD NEWS for Apoe 4/3!!!  

    Ok Dr. Davis, I really need your advice on this one.   In following TYP, I have been taking 3200 mg day EPA/DHA fish oil 1.4:1 ratio.   Recent testing shows I have gotten my HS Omega 3 Index to 9.5,  and my Omega 6 to Omega 3 ratio to 2:9  so this pretty good.   Now for the bad news....ever since I started taking 3200 mg day fish oil...over a 2 month period my HDL went from 48 to 38, a whopping 20% reduction in the critically important good HDL that I need to remove plaque.  I exercise extensively, and I also take 10mg day crestor (crestor is one of the few statins that's supposed to raise HDL not lower it). Now,  I have heard from several sources that Fish Oil (more than 1000 mg day) supplements are actually BAD for Apoe4/3 people because it lowers HDL.  So now I am confused Dr. Davis.....do I follow your TYP advise and stay on 3200 mg day fish oil in order to keep a close to 10 HS Omega 3 Index....but suffer lower HDL and less plaque removal/reversal....or do I stop the Fish oil in order to raise my HDL  but suffer the risks of little to no fish oil??

    Please advise...

    11/7/2011 11:02:03 PM |

    Hi Adam,
    HDL drop can be due to accelerated small HDL's  breakdown/clearance & if that was mostly lingering small HDL then it didn't have much reverse cholesterol transport function left in it anyway. If total HDL drops but small HDL turnover is  now more optimal &/or if it is a greater % of the large HDL then there is better reverse cholesterol transport dynamic despite the total HDL drop.

    ApoE has 299 distinct amino acid positions & the difference between the 3 types are due to which amino acid is in positions 112 & 158 ( respectively ApoE4 @112=arginine & @158 =arginine, ApoE3 @112=cysteine & @158=arginine, ApoE2 @112=cysteine & @158=cysteine). Because ApoE4 has arginine at position 112 this then orientates facing away from the standard grouping of 4 helix at that N-terminal to more closely cozy up to the alpha-helix of the C-terminal that in ApoE naturally overlays the N-terminal. Thus ApoE4 can uniquely feature a "salt bridge" to that C-terminal that affects how ApoE unfolds/functions when ApoE goes to work.
    ApoE's manner of unfolding at it's N-terminal  is crucial to how it deals with lipids, phospholipids (ex: cell membranes)and  proteoglycans on a cell surface. Fish oil alters cell membrane phospholipid composition and then the proteoglycans there must suitably interact with that EPA enriched type of cell surface. Since each ApoE's C-terminal presents an interface that challenges  how that ApoE  works at any target cell the  peculiar ApoE4 "salt bridge" uniquely conditions the way interactions play out. (And each of the separate 3 classic types of ApoE  can get mutations, mostly at positions 136-150, to complicate degree of LDL receptor interaction, etc.)

    Dear Doctor Davis,

    I am wondering if you can clarify the "oxidized LDL Cholesterol" concept.  Including, of course the Small LDL as well.

    I began wondering if the oxidation is primarily in the package, the LDL wrap, the signaling protein, or the internal body of cholesterol itself. Of course, all of the above is also a possibility.

    The nature of the oxidation could be a good clue as to how it is especially detrimental to health, and so far, I haven't found much easily available on the mechanisms of the detrimental effects. While it is useful to know the harmful nature of oxidized small LDL, some insight into the mechanism of harmful effects would be welcome and minimize the nagging question of "Why" for me.

    This might be of interest:

    A large study called the STRRIDE trial looked at the effects of different intensities and volumes of exercise on LDL particle size in sedentary, overweight men and women over eight months [3].  Group A performed 176 minutes of low intensity exercise (walking) per week.  Group B performed 117 minutes per week at a moderate to high intensity (jogging, cycling, or using an elliptical machine).  Group C exercised about the same amount of weekly time as group A, but at the same intensity as group B.  

    As one would likely guess, group C showed the biggest improvement in changing LDLs from small and dense to large and buoyant.  However, a more telling sign was that group B had a stronger effect than group A, despite exercising an hour less per week.  In other words, intensity is more important for improving LDL particle size than volume of exercise.

    A follow-up of the subjects in this study showed some discouraging and encouraging effects on the particle size changes [4].  The discouraging news was that five days of inactivity following the study almost completely attenuated the particle size benefits from the trial.  However, before you start labeling exercise as futile, consider this: while five days of rest basically brought the exercise groups back to baseline LDL particle sizes, they were still much better off than the sedentary control group, who experienced significant digressions in particle size during the course of this study

  • Might-o'chondri-AL

    11/8/2011 7:18:31 PM |

    Hi James Buch,
    The enzyme hepatic lipase's (HL) lipolytic hydrolysis of the phospho-lipids on the LDL surface changes it so that LDL's load of cholesterol esters can get taken out; this reduces the molecule's volume and thus is then small LDL (smLDL). Men have more HL than women, until they go through  menopause, and this propensity toward smLDL ( that can get oxidized) may explain male's earlier tendency of coronary artery disease. Visceral/central obesity trends to upregulate HL & it seems visceral obesity affects men more than women (of course central obesity in both women & men will raise both  genders'  HL enzyme levels). What decreases HL levels are things like calorie restriction & aerobic exercise (sedentary life increases HL).

    Doc harps on avoiding elevated triglycerides after meals that load triglycerides into VLDL  molecules because the enzyme cholesterol ester transfer proetein (CETP) shunts triglycerides from VLDL (& chylomicrons) over to the standard circulating "big bouyant" (large & fluffy) LDL and fosters transfer of cholesterol out of that LDL; the triglyceride takes up less space and thus get smLDL.
    Central obesity usually correlates with elevated triglycerides and increased HL levels. However, if triglyceride genetics (or epigentics from Doc's diet ,etc.)  in the obese without that usual accompanying high triglycerides then that upregulated HL doesn't cause a lot of that individual's standard "big bouyant" LDL to become smLDL. HL also hydrolysizes triglycerides (and phospho-lipids) of chylomicrons, BetaVLDL, IDL, LDL & HDL. Both CETP & HL enzymes being elevated alone, or together, can provoke smLDL - genetic polymorphisms exist for both enzymes.

    sm LDL has less antioxidants left yet it's surface has higher ratio of poly-unsaturated acids which make it's phospho-lipids more at risk of oxidation. And smLDL has less sialic acid left on it's surface which fosters more poly-anion proteoglycan binding that increases the smLDL molecule's transportability across the endothelial lining into the artery wall .
    Doc harps on need for Magnesium because in real time magnesium is what interrupts the oxidation of smLDL from locking into an altered state & then salvaged plain old smLDL doesn't get to go on to be so damaging.

  • Might-o'chondri-AL

    11/9/2011 3:24:05 AM |

    Continued for J. Buch,
    Oxidized small LDL (oxLDL)  has fragments from it's oxidized PUFA (poly-unsaturated fatty acid) that are reactive aldehydes (ex: malon-di-aldehyde & 4-hydroxynoneal-lysine) which then fragment that smLDL's  lipoprotein ApoB.  That peroxidation of a PUFA acyl chain of  the smLDL phospholipid  leaves a type of carboxyl portion that the beta-2-glyco-protein I (Apo H) binds to using a "reactive" ketone as ligand link. Thus it is the position of the "reactive" ketone (keto-cholesteryl-9-carboxy-nonanoate) on the involved cholesterol molecule's spine that determines the % of glyco-protein bonding that occurs (genetics influences ketone placement on a human cholesterol molecule).

    Magnesium (Mg++) in the very early stage of glycated protein (Doc warns against advanced glycation end products) hooking up with LDL reverses the glyco-protein link to the "reactive" ketone. But if deficient Mg allows time to consolidate that contact then only a physiologiclly abnormally high pH will let Mg re-break that bonding.

    Immunological T cells respond (with age & gender differences)  to try to get oxLDL off the artery wall;  and, if there is too much to handle there is the risk of developing a so-called oxidized LDL-containing Immune Complex (oxLDL-IC). And this oxLDL-IC provokes cytokines that perpetuate the inflammation response. Over time and older age there is  less output of a malon-di-aldehyde oxLDL  immune response; which is possibly what leads to long established plaque having less lipid component and more involvement of collagen. It is relatively younger plaque that is unstable and more likely to rupture; the collagen draws in more Calcium and unfortunately provokes artery hardening problems.

    Now the lipid part from this oxLDL-IC gets into an immunological monocyte cell's endosome  and the ApoB gets into that same monocytes lysosome - sub-compartments inside the cytosol (cell interior). Then the lipid part in the endosome triggers heat shock protein (HSP 70/70B) which wrenches things so that the lysosome can't get to work on the lipid and ApoB prevents the lysosome from doing proper interactions at the inside of that cell's membrane to expel  the burdens. Once oxLDL cholesterol esters bulk  up a macrophage (monocyte) due to increasingly futile lysosome  activity  it becomes the notorious "foam" cell. Eventually that macrophage cell dies and the whole load get's polymerized into plaque.

    11/9/2011 8:03:57 PM |

    Hi Dr. Davis - with your indulgence:
    Back to platelets( see above Nov. 7): vascular remodeling with age &/or ROS exposes a bit of phosphatidyl serine  that platelets can "snag" onto as platelets flow along. Key to accomplish platelet snagging is signaling by  the promoter P2gamma12 and normally insulin signaling down inhibits P2gamma12. But, notably for Type II diabetics (and assumedly proportional to an individual's insulin resistance) their insulin doesn't inhibit that snag signal. Type II diabetics also have P2gamma12 upregulated in their platelets. And if anyone is of P2gamma12  haplo-type H2 those individuals will have even more of the receptors for it and therefore an  increased risk of peripheral artery disease. Irregardless of haplo-type, the Type II diabetic's propensity for peripheral artery problems are compounded by  their basal level of excess P2gamma12 .

    Adhesion to the artery then physically involves the platelet surface Glyco-protein Ib & vonWillebrand factor hitched to collagen provoking Integrin 2beta1 (GPVI) so the platelet/collagen sets in place. If the level of promoter P2gamma12 in that challenged site is fortuitously low then the rate of adhesion to the blood vessel is poor. So, predictably, for Type II diabetics the adhesion rate (like platelet secretion & aggregation) is higher than normal. GPVI insult also signals a release of ADP & this ADP (like collagen itself) independently induces aggregation of platelets; the plaque recruits to build itself up to be more fibrous. The plaque matrix serves as nesting for oxLDL & dying macrophage foam cells to polymerize with.

    ROS remodeling agents of the vasculature come from mitochondrial activity and  it appears certain (overlooked) relevant gene pheno-types (and their respective polymorphisms) can be pro-plaque (or preventative) - speaking here in the sense of  a primal influence on plaque risk as well as  tendency of the actual amount of plaque. Sirtuin 5 (Sirt5), a mitochondrial Sirt (there are nuclear Sirt too) binds to Uncoupling Protein 5 (UCP5) and governs that (& other) UCP. Sirt (there are 6 types) remodels chromatin (DNA spooled around a histone ) via histone de-acetylase enzyme; while our UCP (there are 5 types) work in the inner mitochondrial membrane governing the proton electro-chemical gradient that is integral to the chain of oxidative phosphorylation (a way to generate ATP, among other functions).

    Sirt action on DNA includes (among other dynamics) the cellular level encoding of how individual fatty acid metabolism fine tunes -  lipid fatty acids included.Sirt action on DNA includes (among other dynamics) the cellular level encoding of how individual fatty acid metabolism fine tunes -  lipid fatty acids included. Doc's diet/protocol may ( I suggest) sometimes  tweak out favorable health response(s) via induced epigenetics, because of remodeling that is induced in the chromation DNA unit packaging . Sirt's histone de-acetylase working depends on NAD- to drive Sirt and Doc's diet/protocol theoretically seems to be capable of altering NAD flow patterns from his weaning of cells'  mitochondria off of glucose.

    UCP5  rules the inner mitochondrial membrane potential & the rate of oxygen use, which can become relevant to ROS levels. Both UCP5 and Sirt5 are upregulated in hypertension and Type II diabetics; the confluence of having geneticly more UCP5 along with Sirt5 are implicated in increased carotid artery plaque. (Of course nothing is linear in humans so haplo-type T- carrier UCP5 polymorphism rs5977238 benefit with less plaque risk and reduced plaque numbers.) Note: I am skipping over other Sirt & UCP; but will add that lots of pheno-typic UCP1 spins out extra amounts of reactive super oxide to drive down nitric oxide and implicated in accelerated aging of the vasculature.

    Might/Doc - Does this mean that if you DONT have proper insulin receptor response that all of the things listed in the last paragraph become untrue? (meaning bad?)

    Would this mean that you are implying a low carb diet would be the best solution due to the insulin issues?

    I ask because I cannot raise my HDL for the life of me. It is completely stalled at 40. And my LDL is primarily small dense kind. I have only really had this problem since going "LC Paleo" and adding a ton of sat fat to my diet but then I added back in starches and other carbs and became more moderate carb, while still continuing to eat bacon/eggs/cheese/cream/butter/beef/coconut oil/ghee/nuts etc.

    Now I've got people telling me to go back to LC, and exactly the reverse, people telling me that I need to cut out the fats including dairy and go low sat fat.

    HI STG,
    My hope here is that I never hijack Dr. Davis'  blog ( I never personally posted on Hyperlipid blog).  I trust  Doc's readers know he is not responsible for any errors I make. Being semi-retired from consulting on agro-industrial projects in developing countries I feed my mind by keeping up with health science & commenting here about correlations to Doc's work.

  • Might-o'chondri-AL

    11/12/2011 9:33:23 AM |

    Hi J. Kronk,
    Saw your 11 Nov. query &  feel diet advice here is for Doc to offer (not me). Doc discusses ApoE pheno-types he restricts dietary fat for. You "tagged" me where I  was elaborating on platelets' interaction with insulin & how insulin resistance is a game changer (not sure what confusing).

    If one is insulin resistant then the signaling to build-up (anabolism) from insulin is selectively diminished and consequently break-down (catabolism) signals get  into play. Proteo-lysis is protein cleaving and HDL's protein component can be more rapidly subject to proteo-lysis; which I presume (?) is why/how some people degrade their HDL so quickly. Genetic quirks (& gender) also hit HDL levels notably;  yet  if quick enough turnover the "stale" HDL  might be being replaced by more functional HDL. According to the "HATS" study HDL alone is not a predictor of coronary artery disease mortality.

    Niacin usually decreases rate of catabolism of HDL,  it helps secrete more ApoA1 to make into HDL & decreases amount of  smLDL. Niacin isn't perfect since it alters the extent to which HL (hepatic lipase enzyme) can work on a  HDL molecule to morph  it into the kind of HDL that has the maximum reverse cholesterol transport capability. HL is what hydrolyses the triglycerides in HDL - so, basicly if HDL loaded with trigs it has sparser room for scavenging cholesterol.


    One's genetic response to increased levels of circulating palmitate free fatty acid can interfere with insulin signalling in the liver. Whether clinically insulin resistant or due to a genetic quirk (you?),  palmitate can phosphorylate liver insulin receptors in a manner unlike "normal" individuals do in the Akt process (insulin normally should get Akt going to stop liver gluco-neo-genesis - since insulin has glucose to drive into cells ). Essentially "excess" palmitate, in this example, is causing only a partial phosphorylation of Akt & is how researchers can use very high fat diets to induce experimental diabetes .

    I don't hear you being insulin resistant, so address genetics of Protein Phosphatase 2A (PP2A), which  has components involved in it's regulation and is subject to different structure. How PP2A parts interact with distinct parts of the Akt molecule can  impair some interactions,  yet leave other parts of Akt responsive ( to do what Akt  is normally designed to do). Palmitate can raise PP2A levels in the liver by 30%; so basically the more PP2A  around and/or the molecule's genetic tweaks the weaker a key part of  the liver's Akt response is going to be.

    Since palmitate  being in the liver does not stop insulin there from fostering more trigs there are still post-prandial trigs going into the VLDL . In other words the liver insulin resistance and rogue genetics can leave the part of Akt that governs lipo-genesis still responsive to insulin. Doc warns us about trig enriched VLDL & chylomicrons promptly driving  smLDL that doesn't degrade & small particle numbers measure high; he is more adamant about post-prandial trigs but genetic high overnight trigs can occur.

    I don't think coconut oil acts the same way high animal fat sometimes does on Akt . We internally make palmitate when acetyl-CoA acted on by enzyme acetyl CoA carboxylase  to make malonyl-CoA that fatty acid synthase converts to palmitate. I think most of coconut oil's fatty acids are metabolized before getting into that pathway so maybe coconut oil is worth parsing when genetics or insulin resistance drives up smLDL.

    Mito..
    Excuse my error about you posting on the Hyperlipid. I guess I have read your posts elsewhere. In any case, your posts are very educational and explain precisely the biochemistry  Thanks for sharing your knowledge!

    Hi Dr. Davis,
    I’m 47 yrs old. I’ve had migraines since I was a teen and I developed Athsma this past January (hate it). During the process of discovery the drs found I have a 50% blockage in one of the 5, non critical, arteries running along the back of my heart. Scared me, to say the least. I’ve always eaten quite healthfully (for what I knew), am thin @ 6′ 1″/155lbs (was 175lbs in Jan.). Had total cholesterol of 200/LDL of 146/HDL of 50. Drs wanted me to do Lipitor. Researched and said, “No, thanks.” Started exercising 5-6 days/wk (lifting + walk/run), taking red yeast rice, fish oils, fish, no meat, no dairy, no eggs, lots of veggies/fruit, etc., but still eat beans, oats (every AM), occasional wraps. After 6 wks my blood work (VAP) was as follows: LDL=86, HDL=43, VLDL=17, TOT. CHOL=146, Trigycerides=66, Non-HDL (LDL+VLDL)=103.

    Seemed GREAT to me! The dr wasn’t impressed. Said my ‘particle size’ was small: LDL1(a)=8.1, LDL2(a)=0, LDL3(b)=39.5, LDL4(b)=24.9. Density Pattern=B.

    I’ve continued but don’t know how to elevate my HDL and reduce the particle size/change the pattern to the more favorable ‘A’. Getting down about this. Working hard but, seems like I can’t find answers that work, anywhere! What might you would work in my situation? Also, Is niacin ANDRed Yeast Rice a bad idea?
    I’ll hang up and listen. Thank you,
    Mark

    PS - I left this post on another page, as well.

Trapped in a low-fat world

Trapped in a low-fat world

If you would like to...

--Reduce (good) HDL

--Raise triglycerides, sometimes by hundreds of points

--Raise blood sugar into the pre-diabetic range

--Raise blood pressure

--Accelerate coronary plaque growth

then go on a low-fat diet like the one promoted by long-time super low-fat advocate, Dr. Dean Ornish. Every day I have to educate patients that a low-fat diet as advocated by Dr. Ornish is a destructive, counter-productive process that makes coronary plaque grow and increases your heart scan score.

If you want to gain control over coronary plaque, do not follow the Ornish program or anything resembling it. The Ornish program is a dead end.

Instead, the crucial components of a healthy diet for plaque control are:

--Low saturated and hydrogenated fat, but not low all fats.

--High monounsaturated and omega-3 fats

--Low glycemic index (i.e., slow sugar release)

--High fiber

That simple. An excellent program to put these limits to practical use is the South Beach Diet. Or, follow the more detailed guidelines on the Track Your Plaque website (open content section).

    If it is such a dead end, please comment on the angoigrams and PET scans in Dr. Caldwell Esselstyns 2007 book Reversing and Preventing Heart Disease.

    It seems clear from his research, published in the JAMA, that super low fat, plant base nutrition does in fact work. Clearly your methods seem to be working, but does that mean your methods are the only way?

    Do we really need to go low saturated fat?
