Vitamin D deficiency is rampant

12. May 2006 William Davis (0)
Today alone I've seen several people with severe deficiencies of vitamin D.

We're now checking everyone's blood vitamin D level at the start of the program. The measure that most accurately reflects your vitamin D status is 25-OH-vitamin D3. This is very confusing to many physicians, who traditionally have thought of 1,25-di-Hydroxy vitamin D3 as the standard test to measure. What they're failing to recognize is that this second measure is a kidney product, not a reflection of vitamin D status.

Using 25-OH-vitamin D3, several people today alone had levels of <10 ng/ml, clearly in the category of severe deficiency (generally regarded as <20ng/ml).

The majority of people we see in the office are Wisconsin residents. It's no wonder they're deficient. Although it's mid-May, we've seen the sun only a handful of days this year. And most of the days have been too chilly to wear short sleeves and shorts to permit sufficient surface area for UV exposure.

Living in a sunny climate, however, is no guarantee that you have sufficient blood vitamin D levels. Two recent studies have shown that 30-50% of the residents of sunny southern Florida and Hawaii are also deficient. (Why, I'm not sure.)

Although our experience thus far is anecdotal in several hundred people, my impression is that people who have normal blood levels of vitamin D (we regard normal as 45-50 ng/ml) have a far easier time of halting or regressing coronary plaque.

Vitamin D is among the most exciting nutritional tools we've come across in a long time. The conversation is making the media, which impresses me tremendously, given the fact that nobody stands to profit financially to any significant degree through vitamin D supplementation.

For a wonderful collection of discussions on vitamin D, go to Dr. John Cannell's website, www.vitaminDcouncil.com. You'll find a huge quantity of scientific background and conversation on the whole idea. I believe you will be thoroughly impressed with just how powerful the argument in favor of vitamin D has become.

What if wheat products were illegal?

11. May 2006 William Davis (3)
Imagine if anything made of wheat were illegal: bread, bagels, crackers, pasta, pretzels, donuts, Shredded Wheat cereal, Raisin Bran, pastry, cookies, cakes, cupcakes. . . Your grocery store would then be unable to carry any of these products.

How empty would the grocery store shelves be?

There would be very little. The stores would be filled instead with vegetables and fruits, meats, and dairy products. But aisle after aisle would be empty. There'd be no cereal aisle. There'd be no snack chip aisle. The ordinarily overcrowded bread shelves wouldn't be there.

Bakery? Nope, not there either. Pasta and noodles? Empty. How about cakes and pastries? Also gone.

Getting the picture? American groceries are dominated by wheat products. What would happen to your health and the health of your family if wheat were abruptly removed from your choices? Would you be less healthy?

No. In fact, your health would be hugely improved. You'd lose a significant quantity of weight. Extraordinary numbers of people would lose diabetic or pre-diabetic tendencies. Feelings of sluggishness, sleepiness, and moodiness would dissolve. Blood pressure would be reduced. The incidence of cancer, skin disease, and inflammatory diseases would plumet.

From a plaque control perspective, your HDL cholesterol would rise, triglycerides drop. Small LDL would improve dramatically.

The message: Slash wheat products from your diet. Yes, you'll miss the smell and taste of freshly baked bread. But you'll do it for many more healthy years. And you may do it without a 14 inch scar in your chest.

The sobering tale of small LDL

10. May 2006 William Davis (0)
Every day, I learn to respect small LDL more and more.

Small LDL particles, and its evil partner, low HDL, is among the most common reasons why someone fails to fully gain control of coronary plaque and heart disease risk.

Just yesterday, I saw a slender businessman (6 feet 1 inch in height, 186 lb.) whose small pattern persisted despite niacin, fish oil, oat bran, and raw almonds. We generally think of small LDL as an overweight person's pattern, but in some people the genetics are quite powerful and it can be expressed even in slender people.

The solution: More physical activity and exercise; cut back on processed carbohydrates, particularly wheat products like breads, pasta, crackers, breakfast cereals; think about magnesium (see our two recent reports on magnesium on the www.cureality.com membership website, the latest report to be posted this week); be sure sleep is adequate (gauge this by whether you're energetic during the day and don't fall asleep watching TV or movies). Lack of sufficient physical activity in people with sedentary jobs is probably among the most common reason the small LDL pattern persists.

Ignore small LDL and it can be like a hidden cancer in your body, growing and metastasizing (not literally, of course), fueling coronary plaque growth. Be sure your doctor assesses whether you have small LDL if you hope to gain control of your coronary risk.

Burn off the fat

9. May 2006 William Davis (0)

If you've ever wondered just how many calories you're burning with various activities like yard work, driving, climbing stairs, etc. go to this great website that will calculate it for you: http://www.caloriecontrol.org/exercalc.html.

Here are some examples:


Dancing for 30 minutes(fast, e.g., tango): 193 calories
Yoga for 30 minutes: 204 calories
Washing the car for 30 minutes: 173 calories
Vacuuming for 30 minutes: 88 calories

(All are for a 170 lb person.)

As you see, physical activity does not necessarily have to consist of exercise. It doesn't require fancy equipment or expensive outfits. But it does require you to keep moving. Sedentary work is among the most common reasons I see in my patients for failing to control weight and its associated lipoprotein patterns, like low HDL and small LDL.

If your work is sedentary, then a minimum of 60 minutes of physical activity per day is necessary to begin to correct weight-related patterns. If you gauge by calories burned, then a useful goal is 500 calories per day in physical activity--at a minimum.

Go the distance!

8. May 2006 William Davis (0)
How long should it take to stop or reverse coronary plaque growth? How long will it require to stop your heart scan score of, say, 350, from increasing at the expected rate of 30% per year, slow it down (we say "decelerate") to less than 30%, or stop it altogether? Or, actually reduce your score?

It can vary widely. Several simple patterns do seem to emerge, however. Our experience is that lower scores, particularly less than 100 at the start, are easier to gain control over. Scores of 50 or less, in fact, commonly can return to zero.

Higher scores, particularly those >1000, are more difficult to slow or reduce, though we've done it many times. You'll generally have to try harder and it may take longer. It's not uncommon to not stop plaque growth with a starting score this high until your 2nd or 3rd year of effort.

Sometimes it may take even longer. An occasional person requires four or five years to gain control. And there are, unfortunately, some people who never really gain complete control. They slow plaque growth compared to what it would have been with conventional efforts, but never completely halt growth. Why? Sometimes it's a matter of less than full commitment. Other times, we just don't know. Thankfully, these especially difficult cases are few and the majority enjoy substantial slowing or reversal.

Since, in some people, success may take time, you've got to stick it out. Have you ever gotten lost in a strange city only to find out later that the place you were looking for was right around the corner? It can be the same way with stopping coronary plaque growth. If you start with a score of 1000 and, after two years of effort, you've only slowed growth to 11% per year and then give up in frustration, you may have missed the opportunity to have stopped growth entirely in your third year.

All we can do is tip the scales heavily in your favor. We provide you with the best tools known. You've got to provide the commitment, the consistent effort of taking your supplements or medication, making the lifestyle changes, choosing the right foods and avoiding the wrong ones. But you've got to go the distance and not give up too easily.

What you need is an expert in health!

5. May 2006 William Davis (0)
Where can you find an expert in health?

In my experience, they're hard--very hard--to find.

Your hospital? Certainly not the hospitals I know. The hospitals I know are experts in disease, but not in health. Hospitals are helpful when you're sick. But if you're well and would like to stay that way, there's no reason to hang around a hospital. Prevent cancer, prevent heart disease, stay well? There's no place for this conversation in a hospital.

In fact, hospital staff are among the most unhealthy people I come across. Obesity is a nationwide problem affecting millions of Americans. But it's especially a problem among people who work in hospitals. I shudder in horror when I go to a hospital cafeteria and witness the sorts of food they serve in hospitals and see what the staff eat. Should they be regarded as experts in health?

How about doctors? If you associate with physicians like the ones I know, most have lots of knowledge about disease, but little understanding of health. A rare one has insight and interest in health.

I went to a recent meeting with my cardiology colleagues. Food served: pizza, Coca-Cola, spaghetti, fried onion rings, white bread with butter. They all dug in without hesitation. Over half were miserably overweight. Several were, in fact, diabetic; several more, pre-diabetic. I know that at least several are smokers. Experts in health?

Drug companies? Well, they're interested in health only as far as it provides profits. But health for its own sake? Ask anybody from a drug manufacturer about their views on the nutritional supplement movement and watch them sneer.

Food manufacturers? You mean like Coca-Cola, Pepsi-Cola, Nabisco, and General Mills? How about fast-food operations like McDonald's, Pizza Hut, and KFC?

The message: Know where to look for genuine information on health. You won't get it from hospitals. You won't get it from drug company marketing. For the most part, you can't even get it from your physician.

Instead, you're going to witness a broad movement towards self-empowerment in health, fueled by the internet and services like ours (Track Your Plaque). These are information resources that are not driven by profit, intent on providing truth, and not afraid to reject prevailing views.

It does not mean that hospitals are unnecessary, or that food manufacturers are evil, or that fast food should be legislated out of existence. We live in a capitalistic society, driven by supply and demand. Hopefully, demand is borne from educated choices from informed consumers. That's where information that's reliable, credible, and not profit driven come in.

Lipoprotein(a) and small LDL

4. May 2006 William Davis (1)
It's been my suspicion for some time that the combination of lipoprotein(a), or Lp(a), in combination with small LDL particles is a really bad risk for heart disease. People with this combination seem to have much higher heart scan scores for age than others. This seems to be a pattern that we'll see in the occasional woman less than 50 years old who already has a high heaert scan score. (It's unusual for women to have detectable coronary plaque before age 50.)

Very little data exists to support this idea and we are in the process of performing a small study to see whether it's true or not. My gut sense: it's among the most potent causes of coronary plaque around.

Case in point: Even though I spend a great deal of my time and energy advocating heart disease prevention, I still maintain my hospital privileges and skills. I had to cover one of the emergency rooms in town this past weekend (a requirement to maintain my hospital privileges).

One of the patients I saw was a 40-year old man--we'll call him Roland-- suffering a very large heart attack, a so-called "anterior myocardial infarction", or a heart attack involving the most important front portion of the heart. Thankfully, he came to the ER within 45 minutes after his chest pain started. The situation was immediately obvious and I was called to the ER. We quickly took him to the cardiac catheterization laboratory and put a stent in the left anterior descending artery and flow was restored. His chest pain dissipated over the next few minutes.

Nonetheless, Roland was left with a large area of reduced contraction of his heart muscle. Only time will tell how much recovery he'll have.

Roland was extremely lucky. The majority of people with closure of the artery that he'd experienced die within minutes. He did, in fact, "arrest" briefly, i.e., his heart became electrically unstable, though he recovered promptly.

Along with the multiple tubes of blood we required to run tests for his heart attack management, we had Roland's lipids and other measures sent off, as well. Wouldn't you know: Lp(a) and small LDL. This may have accounted for a heart attack at age 40.

Keep a lookout for this when you have lipoprotein testing. Conveniently, niacin can be used to treat both patterns, though higher doses are generally required for the Lp(a) part of the pattern. It's also my belief that the sort of Lp(a) measurement performed by the Liposcience laboratory (www.liposcience.com) is superior. They use a particle number based measure, not a weight-based measure. It is therefore independent of particle size, which can vary. Further work will, I believe, reveal some very important insights into the dreaded Lp(a).

"Please don't tell my doctor I had a heart scan!"

30. April 2006 William Davis (1)
I overheard this recent conversation between a CT technologist and a 53-year old woman (who I'll call Joan) who just had a scan at a heart scan center:


CT Tech: It appears to me that you have a moderate quantity of coronary plaque. But you should know that this is a lot of plaque for a woman in your age group. A cardiologist will review your scan after it's been put through a software program that allows us to score your images.

Joan: (Sighing) I guess now I know. I've always suspected that I would have some plaque because of my mother. I just don't want to go through what she had to.

CT Tech: Then it's really important that you discuss these results with your doctor. If you wrote your doctor's name on the information sheet, we'll send him the results.

Joan: Oh, no! Don't send my doctor the results! I already asked him if I should get a scan and he said there was no reason to. He said he already knew that my cholesterol was kind of high and that was everything he needed to know. He actually got kind of irritated when I asked. So I think it's best that he doesn't get involved.


This is a conversation that I've overheard many times. (I'm not intentionally an eavesdropper; the physician reading station at the scan center where I interpret scans--Milwaukee Heart Scan--is situated so that I easily overhear conversations between the technologists and patients as they review images immediately after undergoing a scan.)

If Joan feels uncomfortable discussing her heart scan results with her doctor, where can she turn? Get another opinion? Rely on family and friends? Keep it a secret? Read up about heart disease on the internet? Ignore her heart scan?

I've seen people do all of these things. Ideally, people like Joan would simply tell their doctor about their scan and review the results. He/she would then 1) Discuss the implications of the scan, 2) Identify all concealed causes of plaque, and then 3) Help construct an effective program to gain control of plaque to halt or reverse its growth. Well, in my experience, fat chance. 98% of the time it won't happen.

I think it will happen in 10-20 years as public dissatisfaction with the limited answers provided through conventional routes grows and compels physicians to sit up and take notice that people are dying around them every day because of ignorance, misinformation, and greed.

But in 2006, if you're in a situation like Joan--your doctor is giving you lame answers to your questions or dismissing your concerns as neurotic--then PLEASE, PLEASE, PLEASE take advantage of the universe of tools in the Track Your Plaque program.

People tell me sometimes that our program is not that easy--it requires reading, thinking, follow-through, and often asking (persuading?) your doctor that some extra steps (like blood work) need to be performed. The alternative? Take Lipitor and keep your mouth shut? Just accept your fate, grin and bear it, hoping luck will hold out? To me, there's no rational choice here.

Doctor, why do I have heart disease?

30. April 2006 William Davis (0)
I see a great many people in my practice who come for a 2nd opinion regarding their coronary disease.

When I ask patients whether they ever asked their primary doctor or cardiologist why they have heart disease in the first place, I get one of several responses:

1) My doctor said it from high cholesterol.

2) My doctor said it was "genetic" or "part of your family history" and so unidentifiable and uncorrectable. Tough luck.

3) I didn't ask and they didn't tell me.


Let's talk about each of these.

Can heart disease be only from high cholesterol and, if so, can taking a statin cholesterol drug be a "cure"? In the vast majority of cases, in my experience, cholesterol by itself is rarely the only identifiable cause of coronary disease.

Most people have a multitude of causes (e.g., small LDL, low HDL, vitamin D deficiency, concealed pre-diabetic patterns, etc.). This explains why many people with high LDL don't have heart disease and why others with low HDL do have heart disease. High LDL cholesterol is only part of the cause.

Does "genetic" or being part of your family's history also mean unidentifiable and uncorrectable? Absolutely not.

What your doctor is really saying is "I don't know enough to diagnose the causes because I haven't kept up with the scientific literature", or "I don't want to be bothered with this because it takes a lot of time and pays me very little money; I'd rather wait until you need a stent ", or "The drug representatives haven't told me about any new drugs". This is ignorance and laziness at best, greed and profiteering at worst. Don't fall for it. I hope that by now you recognize that the great majority of causes of heart disease are identifiable and correctable.

If you didn't think to ask, now you know that you should. If you and your doctor don't think about why you have coronary plaque in the first place, how can you develop a program to control it?

You need to ask. And you need to get confident answers. "I don't know" or "It's genetic" and the like are unacceptable.

Pill pushers

28. April 2006 William Davis (1)
Have you read the latest cover story from Forbes magazine? It's entitled "Pill Pushers: How the drug industry abandoned science for salesmanship".

It's great reading. (A condensed version is available at the www.forbes.com website: http://www.forbes.com/business/forbes/2006/0508/094a.html. They require you to provide your e-mail address though it's free.)

Drug industry advertising has raised consciousness of all the prescription therapies available for us--that's good. However, they've gone so far overboard trying to squeeze more and more revenues out of drugs that they've cost this country a huge amount in increased health care costs and even lost lives. (Forbes does a great job of summarizing some of these instances.)

Drugs like Lipitor, Crestor, Zocor; diabetes agents; anti-hypertensive agents, etc., that is, medications taken chronically, a huge financial bonanzas for drug companies. Not only do they get $100-200 per month, but they get it month after month after month. That's per drug.

Now not all medications are bad or unnecessary. There are times when they can be truly necessary and beneficial. But don't rely on drug company advertising to tell us when.

Unexpected effects of a wheat-free diet

17. September 2009 William Davis (59)
Wheat elimination continues to yield explosive and unexpected health benefits.

I initially asked patients in the office to eliminate wheat because I wanted to help them reduce blood sugar and pre-diabetic tendencies.

A patient would come to the office, for example, with a blood sugar of 118 mg/dl (in the pre-diabetic range) and the other phenomena of pre-diabetes or metabolic syndrome (high blood pressure, high inflammation/c-reactive protein, low HDL, high triglycerides, small LDL), and the characteristic wheat belly. Eliminate wheat and, within three months, they lose 30 lbs, blood sugar drops to normal, blood pressure drops, triglycerides drop by several hundred milligrams, HDL goes up, small LDL plummets, c-reactive protein drops.

People also felt better, with flat tummies and more energy. But they also developed benefits I did not anticipate:

--Improved rheumatoid arthritis--I have seen this time and time again. Eliminate wheat and the painful thumbs, fingers, and other joints clear up dramatically. Many former rheumatoid sufferers people tell me that one cracker or pretzel will trigger a painful throbbing reminder that lasts a couple of hours.

--Improved ulcerative colitis--People incapacitated with pain, cramping, and diarrhea of ulcerative colitis (who are negative for the antibodies for celiac disease) can experience marked improvement. I've seen people be able to stop all their nasty colitis medications just by eliminating wheat.

--Reduction or elimination of irritable bowel syndrome

--Reduction or elimination of gastroesophageal reflux

--Better mood--Eliminating wheat makes you happier and experience more stable moods. Just as wheat is responsible for a subset of schizophrenia and bipolar illness (this is fact), and wheat elimination generates dramatic improvement, when you or I eliminate wheat, we also experience a "smoothing" of mood swings.

--Better libido--I'm not sure whether this is a consequence of losing a belly the size of a watermelon or improvement in sex hormones (esp. testosterone) or endothelial responses, but more interest in sex typically develops.

--Better complexion--I'm not entirely sure why, but various rashes will often dissipate, bags under the eyes are reduced, itching in funny places stops.


It's also peculiar how, after someone eliminates wheat for several months, re-exposure of an errant cracker or sandwich results in cramping and diarrhea in about 30% of people.

Obviously, people with celiac disease, who can even die of exposure to wheat, are even worse. What other common food do you know of that makes us sick so often, even occasionally with fatal outcome?

Is Lp(a) part of your legacy to your children?

15. September 2009 William Davis (21)
If you have lipoprotein(a), Lp(a)--the most aggressive known cause of heart disease that no one has heard of--then you need to tell your children.

Lp(a) is a "cleanly" inherited genetic pattern: If either parent has it, there's a 50% chance that you have it. If you have it, then there's a 50% likelihood that each of your children has it. (Note that each child experiences a likelihood of 50%, not 50% of your children. This is because each child is conceived as an independent statistical event. So much for romance!)

The atherogenicity (plaque-causing potential) of Lp(a) also tends to get transmitted. In other words, if your Dad had a heart attack at age 50 due to Lp(a) and you share Lp(a), then you likely share a similar magnitude of risk as your Dad. If your Mom had Lp(a), though passed quietly at age 89 without any overt evidence of heart disease, then you are likely to share the relatively benign form of Lp(a).

For most of us with Lp(a), however, it is best to assume that it has at least some potential for causing heart disease, being the most aggressive cause known. (That is, until we have the ability in everyday clinical practice to characterize Lp(a) by assessing such factors as the size of the apoprotein(a) molecule, the number of kringle "repeats" on the tail, etc. Until then, we need to rely on the crude, though helpful, observation of family history.)

At what age should you inform your children? There's no hard-and-fast rule. However, I generally suggest to patients that they talk about Lp(a) with their children when they reach their 20s or 30s, old enough to begin to understand the implications and begin to think about adopting healthier lifestyles. Is treatment required at, say, age 35? That depends on the pattern of Lp(a)-related heart disease in the family: With exceptionally aggressive forms, it might be reasonable to begin treatment at this relatively early age.

Do "Heart Healthy" sterols cause heart disease?

9. September 2009 William Davis (19)
The sterol question continues to pop up.

Sterols are an ingredient widely added by food manufacturers that allows a "heart healthy" claim, since sterols have been shown to reduce LDL cholesterol (at least transiently). HOWEVER, sterols have also been implicated in possibly increasing risk for heart disease. After all, people with the genetic condition called sitosterolemia absorb sterols into the blood and develop coronary heart disease in their teens and twenties. Those of us without sitosterolemia who increase sterol intake with sterol-enriched foods increase blood levels of sterols several-fold. Is this healthy, or does it contribute to coronary plaque as it does in people with sitosterolemia?

Below, I've reprinted a previous Heart Scan Blog post on sterols.


Sterols should be outlawed

While sterols occur naturally in small quantities in food (nuts, vegetables, oils), food manufacturers are adding them to processed foods in order to earn a "heart healthy" claim.

The FDA approved a cholesterol-reducing indication for sterols , the American Heart Association recommends 200 mg per day as part of its Therapeutic Lifestyle Change diet, and WebMD gushes about the LDL-reducing benefits of sterols added to foods.


Sterols--the same substance that, when absorbed to high levels into the blood in a genetic disorder called "sitosterolemia"--causes extravagant atherosclerosis in young people.

The case against sterols, studies documenting its coronary disease- and valve disease-promoting effects, is building:

Higher blood levels of sterols increase cardiovascular events:
Plasma sitosterol elevations are associated with an increased incidence of coronary events in men: results of a nested case-control analysis of the Prospective Cardiovascular Münster (PROCAM) study.

Sterols can be recovered from diseased aortic valves:
Accumulation of cholesterol precursors and plant sterols in human stenotic aortic valves.

Sterols are incorporated into carotid atherosclerotic plaque:
Plant sterols in serum and in atherosclerotic plaques of patients undergoing carotid endarterectomy.




Though the data are mixed:

Moderately elevated plant sterol levels are associated with reduced cardiovascular risk--the LASA study.

No association between plasma levels of plant sterols and atherosclerosis in mice and men.




The food industry has vigorously pursued the sterol-as-heart-healthy strategy, based on studies conclusively demonstrating LDL-reducing effects. But do sterols that gain entry into the blood increase atherosclerosis regardless of LDL reduction? That's the huge unanswered question.

Despite the uncertainties, the list of sterol-supplemented foods is expanding rapidly:




Each Nature Valley Healthy Heart Bar contains 400 mg sterols.












HeartWise orange juice contains 1000 mg sterols per 8 oz serving.













Promise SuperShots contains 400 mg sterols per container.














Corozonas has an entire line of chips that contain added sterols, 400 mg per 1 oz serving.














MonaVie Acai juice, "Pulse," contains 400 mg sterols per 2 oz serving.














Kardea olive oil has 500 mg sterols per 14 gram serving.










WebMD has a table that they say can help you choose "foods" that are sterol-rich.

In my view, sterols should not have been approved without more extensive safety data. Just as Vioxx's potential for increasing heart attack did not become apparent until after FDA approval and widespread use, I fear the same may be ahead for sterols: dissemination throughout the processed food supply, people using large, unnatural quantities from multiple products, eventually . . . increased heart attacks, strokes, aortic valve disease.

Until there is clarification on this issue, I would urge everyone to avoid sterol-added "heart healthy" products.


Some more info on sterols in a previous Heart Scan Blog post: Are sterols the new trans fat? .

Why obese people can't fast

9. September 2009 William Davis (21)
Why do obese people claim it is impossible to fast?

Most overweight people are terrified at the prospect of facing any period of time without ready access to food. Persuading them to begin a program of intermittent fasting is a hopeless cause. They just refuse.

Contrary to popular opinion, this is not just glutonny at work. It is the effect of what I call "the cycle of hunger," the 2-hour up and down cycle of rising sugar and insulin, followed by their inevitable fall. The precipitous fall of sugar and insulin triggers mental fogginess, fatigue, and insatiable hunger. (By the way, this is the same phenomenon underlying the silly notion of "grazing.")

According to an LA Times article, fasting may be difficult to impossible for some people:

"Ruth Frechman, a registered dietitian in Burbank and spokeswoman for the American Dietetic Assn., says she frequently sees such extreme strategies backfire. 'You're hungry, fatigued, irritable. Fasting is not very comfortable. People try to cut back one day and the next day they're starving and they overeat.'"
(Not surprising, coming from the American Diatetic Assn. They, along with such agencies as the American Diabetes Association, are vocal proponents of low-fat, high-carbohydrate, "healthy whole grain" diets--you know, the diets that make us fat and diabetic.)

Ms. Frechman is correct: Having someone engage in a period of fasting, no matter how brief, when the diet leading up to the fast is filled with "healthy whole grains" and other carbohydrates will result in painful hunger that eventually overcomes any effort. A period of overeating typically follows the aborted attempt.

Fasting cannot work as long as the 2-hour cycle of hunger continues. The first step: Eliminate the 2-hour cycle of hunger by dramatically reducing or eliminating carbohydrates. Our preferred method is to eliminate wheat, cornstarch, and sugars. (Just be aware of wheat withdrawal, the fatigue that develops in the first 5 days after wheat elimination that affects up to 30% of people.)

Once wheat, cornstarch, and sugars are eliminated, hunger reverts to that of physiologic need--appetite will be smaller and less intense, since it is driven by your body's needs, not by abnormal stimulation from wheat, cornstarch, and sugar. The fear of not having food dissolves, the 2-hour cycle of mental fogginess, fatigue, and hunger will be gone.

Intermittent fasting is a wonderful strategy for reducing weight; gaining control over lipids, lipoproteins, and coronary plaque; regaining appreciation for food; reducing appetite. But it's not even worth trying unless you've already eliminated the unnatural appetite triggers that will booby-trap any fasting effort.

Test your own thyroid

7. September 2009 William Davis (15)
134 people responded to the latest Heart Scan Blog poll:


When I ask my doctor to test my thyroid, he/she:

Accommodates me without question 45 (33%)

Questions why, but orders the tests 49 (36%)

Refuses because you seem "healthy" 20 (14%)

Refuses without explanation 4 (2%)

Ridicules your request 16 (11%)



That's better than I anticipated: 69% of physicians complied with this small request. After all, you're not asking for major surgery. You're just asking for a very basic test, as basic as a blood count or electrolytes. 36% of respondents said that their doctor asked why, but still complied; this is simply practicing good medicine--If there is a problem, your doctor would like to know about it.

However, the remainder--31%--were refused in one way or another. Incredibly, 11% were ridiculed.

Although this was not asked in the poll, I believe that it is a safe assumption that you asked with good reason: you're abnormally fatigued, you have been gaining weight for no apparent reason or can't lose weight despite substantial effort, or you feel cold at inappropriate times.

Let's say you're tired. Ever since last summer, you've suffered a gradual decline in energy.

So you ask your doctor to assess your thyroid. He refuses. "You're just fine! There's nothing wrong with you."

You disagree. In fact, you are quite convinced that there is something physically wrong. What do you do?

You could:

--Drink more coffee
--Exercise more in the hopes that it will snap you out of your lethargy
--Sleep more
--Take stimulants of various sorts

Or, you could get your thyroid assessed and settle the issue. But how can you get this done when your doctor won't accommodate you, even though you have perfectly fine health insurance and are simply interested in feeling better and preserving your health?

You could test your thyroid yourself. This is why we're making self-testing kits available. Test kits are available here.

This is yet another facet of the powerful revolution that is emerging: Self-directed health.

Trains, planes, and heart scans

4. September 2009 William Davis (10)
A Heart Scan Blog reader posted the following question:

It is not clear to me why getting a cardiac scan is the necessary first step, if in fact the next step would be to bring down small LDL particles which is revealed on a NMR lipoprofile or VAP test. Why isn't the NMR or VAP test the first thing?

Good question. Think of it this way:

Lipoproteins, as measured via VAP (Vertical Auto Profile) or NMR (Nuclear Magnetic Resonance), provide a snapshot of risk from a metabolic viewpoint at that moment. Lipoproteins shift with the tides of age, menopause, weight changes, even what you ate last evening for dinner (especially small LDL). There are also other factors that cause coronary plaque, as well, not revealed through lipoprotein testing, such as vitamin D deficiency, smoking, high blood pressure, phosopholipase A2, lipoprotein(a), inflammatory factors, thyroid dysfunction, omega-3 fatty acid deficiency, etc.

A heart scan, providing a coronary calcium score, provides an indirect measure of coronary plaque that is the sum total of lipoprotein and other plaque-causing factors that have accumulated up to the time of your scan--regardless of the cause.

It means that two females, each 60 years old, with 70% small LDL, HDL 42 mg/dl, triglycerides 150 mg/dl, and mild hypertension, have identical markers for potential coronary risk, but can have widely different heart scan scores. One might have a score of zero, while the other might have a score of 300.

Why would the same panel of causes measured at one moment yield wildly different quantities of plaque? Several reasons:

1) The lifestyles, eating habits, and weight of each woman differed during their earlier years, not currently reflected in this moment's lipid or lipoprotein patterns. Perhpaps one experienced several years of extraordinary stress from a failed marriage, or suffered through two years of depression that caused her to smoke and overeat.

2) There are hidden factors that affect coronary plaque growth that we are presently not able to detect, e.g., vitamin D receptor genotype, cholesteryl-ester transfer protein variants, variation in inflammatory factors. If we can't measure it, we won't know whether it might influence coronary plaque risk.


With all the changes that occur over a person's life, with the uncertainties of yet-to-be-identified causes for coronary plaque, how can you possible know what your risk for heart disease truly is? Yup--a heart scan. Do it and you will know.

D2 and D3 are two different things

3. September 2009 William Davis (15)
Helena posted this instructive comment in response to the Heart Scan Blog post, Weight loss and vitamin D. It illustrates the confusion common among physicians and pharmacists on the differences between D2 and D3.

(Edited slightly for clarity.)

Not many weeks ago a colleague of mine (let’s call him Eric) asked me if I knew the difference between D2 and D3 and I told Eric that D2 comes from irradiated mushrooms and D3 comes from wool. In other words, D3 is the same kind of vitamin as humans get from the sun. Humans just don’t get enough and we can’t produce it on our own, like the sheep can. (D3 is natural for humans, D2 is not.)

After telling Eric this, he asked me how he would know what he is taking and I gave him the medical definitions of them both (D2 = Ergocalciferol; D3 = Cholecaliciferol). Since I was aware that he had gotten his Vitamin D by prescription, I told him “I am 99.9% sure that you are taking D2, but I would be thrilled to find out I am wrong.”

Eric called his pharmacy right away and got the answer I was expecting: ergocalciferol. On confronting the person Eric was talking to, the answer he got back was that Ergocalciferol is the only Vitamin D they are giving out.

A week later, Eric had a new appointment with his doctor and decided to ask him about the D2/D3 issue. The doctor said he knew that there was a difference in them both, but could not say what, not even the basic facts I mentioned above. But the doctor stamped a post-it with what he had sent to the pharmacy just to show Eric. “Vitamin D3; 50,000IU tab” is what the stamp said.

Eric, off course, got confused and was starting to believe that the pharmacy had made a mistake by giving him Ergocalciferol (D2) since the doctor had given him D3, or at least that is what was stamped on the little note he had.

Today, after getting a refill of his Vitamin D he also got and kept all his paperwork that came along with it. Still believing that stamp the doctor had given Eric earlier, he asked me to double and triple check that my definition of D2 and D3 was correct. I did, just for my own sanity, and I was still right.

One of the sheets Eric brought me today was the “Patient Education Monograph” sheet stating the drugs and how to use it and so on. The thing that jumped out the most to me was this:

Generic Name: Vitamin D – Oral
Common Brand name(s): Drisdol, Maximum D3
Identification: PA140 Green Oval Capsule

This is the Drug Eric was given: Vitamin D 1.25 MG softgel; Generic name: Ergocalciferol

My researching mind went into high concentration mood and I started to dig. And this is what I found:

The brand name Drisdol is Ergocalciferol (D2), not D3. The Brand name Maximum D3 seems to be hard to find out there in cyber space as a brand name. But the ones I found that were called Maximum D3 seems to be the real stuff, however none of them required a prescription.

When trying to find out through the identification number on the pills (PA140) I now know for sure that Eric is taking Vitamin D2 and not the preferred Vitamin D3. The brand name, Drisdol, had the identification W on one side and D92 on the other, but it is still Ergocalciferol.

The only conclusion I can draw from all this is that the medical industry does not know or care about the difference in D2 and D3 – it is all same to them. And as long as the pharmacies only give out D2 it does not matter what the doctor prescribe anyway.

I know that people are most likely to be prescribed a D2 pill than to be told to buy over-the-counter D3. But it was almost heart breaking to see the letter D and number 3 right next to the drug Drisdol, as we know is a D2 vitamin. It just didn’t make sense to me that they can be labeled as the same type of medication, when we know it is not!


Incredible.

Why prescribe plant form D2 when you can get perfectly reliable, safe, effective D3--the human form, at the health food store for about $6?

Once again, it's the peculiar false bias of physicians and pharmacists: If it's prescription, it must be good; if it comes from a health food store, it must be bogus.

Humans need human vitamin D. Plain and simple.

Weight loss: Different causes, different solutions

1. September 2009 William Davis (8)
Heart Scan Blog reader, Kris, related this enlightening story of weight loss (slightly edited for clarity).

Kris learned that excess weight is gained through multiple causes. The solutions are therefore multiple, not just one change in diet or two.


I started studying about my thyroid issue much earlier and did lose some weight. But ever since I started following Dr. Davis’s blog, it has given me confidence that I was on the right track. I did have my thyroid and iodine figured out from other sources, but Dr. Davis helped me to understand the issues with not only the thyroid but vitamin D3, fructose, fish oil, niacin, wheat etc. I have lost 43lb in last 14 months.

It seems to me that there are certain percentages of weight connected with different issues. For example, after I gave up alcohol and sugar, I lost about 14lbs from total weight of 243lbs, weight came down to about 229lb. Then it stopped at 229lb, even though I was in the gym almost 5 to 6 days a week with full workouts.

After I changed my thyroid medication to natural thyroid hormones (took synthetic T4 for over 10 years), the weight dropped down further 13lbs or so in matter of few days, shape of the face changed from moon shape/double chin to ordinary long face. Then it kind of stopped at around 213-216 lbs.

After giving up wheat, reducing carbs, increasing protein intake (whey protein, chicken etc. no soya, no fructose) the weight came down another 14lbs. Now it is around 200-202lbs and I am over 6.2 tall with heavy set of bones.

I feel better than I have ever in my life. More stamina, more clarity/no fog, more confidence and 99% of the time relaxed and being able to see the situation from multiple angles.

I use to be able to drink a liter or more jack denial without a problem in one evening but now can’t stand half a can of beer (I miss JD). Drinking alcohol makes me sick. I sleep well and if I wake up in the middle of the night, I have no problem going back to sleep. No more out of breath stair climbing at all.

One other thing: I used to be the most attractive meal to the mosquitoes, but not anymore. This year I haven’t been bitten once. I take my dog to the park everyday and I do not use any mosquito repellent, what a relief. I don’t know if it is because of thyroid, iodine, wheat or something else. Skin texture has changed dramatically. I do not use full soap or shampoo, 20% borax, 10 percent of my soap or shampoo for scent and rest water, mixed in a 500ml bottle. No more dandruff, dry skin, pimples for me.

Dr. Davis I am thankful to people like you who have the ability to see beyond what you have been taught and have the guts to say the way it is. Most of us work to make living on daily basis but some make their living while spreading their knowledge to save lives. Dr Davis you are one of those few people. Please keep it going.

Calling all losers!

I'd like to invite anyone who has followed the Track Your Plaque Break the Weight Barrier program to consider posting their stories and photos on the Heart Scan Blog.

Because our focus is prevention and reversal of coronary heart disease, we have not made an effort to catalog the weight loss experience that people have while on the program. For many, weight loss has been substantial. (Several people this week alone have reported weight loss of 9 to 46 lbs in the past 6 months.)

It would be helpful to hear and see these results.

For those of you who don't mind having a story and photo on this Blog, please come back in future to post your results. You will find this post by entering "weight loss" into the site-specific search bar at the top of the page.

Weight loss and vitamin D

28. August 2009 William Davis (28)
At the start of her program, Penny's 25-hydroxy vitamin D blood level showed the usual deficiency at 22 ng/ml.

She supplemented with 8000 units of vitamin D. Another 25-hydroxy vitamin D blood level several months later showed a level of 67.8 ng/ml, right on target.

But Penny also began our diet, including the elimination of wheat, cornstarch, and sugars, and, over 6 months, lost 34 lbs.

Now a much trimmer 146 lbs (still more to go!), another vitamin D blood level: 111 ng/ml.

Penny's weight loss means that the vitamin D is distributed in a smaller total volume, particularly a lower volume of fat.

This is a common phenomenon with substantial weight loss: lose weight and the need for vitamin D is reduced. The reduction in dose is roughly proportion to the weight lost. Vitamin D should therefore be reassessed with any substantial change in weight of, say, 10 lbs or more, either up or down, because of the influence of fat on vitamin D blood levels.

Some references on this effect:

Men and women over age 65:

Obese women:

African-Americans:

Although the bulk of the effect is most likely due to sequestration by fatty tissue, perhaps less sun exposure in obese people also contributes:
