Throw away total cholesterol!

17. May 2006 William Davis (1)
Richard's total cholesterol without treatment was 186 mg/dl. "That's great!" his doctor declared, referring to the conventional dictum that total cholesterols less than 200 carry low risk. Several fingersticks in a mall kiosk set up by a local hospital to check total cholesterols confirmed Richard's low number.

But after Richard's unexpected hospitalization and two stents for severe coronary blockages, he demanded better answers.

Tragically, the answer was there all along: Despite a "favorable" total cholesterol, his HDL ("good") cholesterol was a miserable 32 mg (ideal >60 mg).

Total cholesterol is actually the sum total of HDL cholesterol, LDL cholesterol, with a contribution from triglycerides. That's why a low total cholesterol can conceal a low HDL.

This situation is quite common. And low HDL is accompanied by a constellation of other undesirable causes of heart disease, most notably small LDL.

Don't accept total cholesterol as your sole measure of risk. It's nearly worthless. If you live in Bangladesh or a third world country, well perhaps that's the best you can get. But if you live in the U.S. or developed world, it's absurd to rely on total cholesterol.

Smart Start not so smart

15. May 2006 William Davis (2)



Kellogg's has crafted a campaign to support the American Heart Association featuring acress Sela Ward. Her attractive face, familiar to many TV and movie viewers, does add a comforting face to their efforts.

What's in this cereal made by the manufacturers of Pop-Tarts, Cheez-It, Rice Krispies, and Chips Deluxe cookies?

There are, indeed, some healthy ingredients: oat bran, potassium; you can even get a version made with soy protein. But there's sugar listed as the second ingredient. High-fructose corn syrup is also listed prominently. (Remember this issue? High-fructose corn syrup causes overwhelming sugar cravings, causes your triglycerides to skyrocket, and is probably among the principal food ingredients that make you obese.)

Upon detailed questioning of my patients struggling to lose weight, this and products like it are often among the "healthy" foods they've gravitated towards. We spend a great deal of time dissuading them of this idea.

A one-cup serving of Smart Start is low in fat (1 gram) but contains 43 grams of carbohydates, of which there are 14 grams of sugar. There are a meager 3 grams of fiber. To me, this sounds like a cupcake.

The Kellogg's people are exceptionally clever marketers. Partner with the American Heart Association and movie stars? Brilliant!

You should trust food manufacturer advertising about as much as you trust drug manufacturer advertising, which is to say not at all.

Kellogg's sold $10 billion dollars of food products last year. They are the world's leading producer of breakfast cereals. They are a leading producer of convenience foods: cookies, crackers, cereal bars, and frozen waffles under the brands Keebler, Pop-Tarts, Eggo, Cheez-It, Nutri-Grain, Rice Krispies, Famous Amos, and Kashi.

Can they cash in on healthy trends? They'll certainly try.

Does anybody have a normal vitamin D level?

15. May 2006 William Davis (0)
We now routinely check everyone's vitamin D blood level at the start of the program. (The measure to obtain is 25-OH-Vitamin D3. This is not to be confused with 1,25-OH2-vitamin D3, which is a kidney function measure.)

Of the 10 people with levels drawn today, none were even close to normal levels (which we define as 50 ng/ml)--not a single one.

The majority were in the range of severe deficiency (<20 ng/ml). Only two had levels in the 30s. None had higher. (Remember: I'm talking about people in Wisconsin, a terribly sunlight-deprived area much of the year. This might not apply quite as vigorously to Florida residents or others in sun-exposed regions.)

Curiously, I've also seen several people this week who had extraordinary quantities of coronary plaque on their heart scans (scores >1000), all of whom had extremely low vitamin D levels. One of these people had fairly unimpressive lipoproteins, with very minimal abnormalities identified. (This is quite unusual, by the way.) It makes you wonder if a profound deficiency of vitamin D is sufficient to act on its own as an instigator of coronary plaque.

The more we examine the issue of vitamin D deficiency, the more fascinating it gets. I suspect we've just scratched the surface and there's a lot more to learn about this tremendously interesting nutrient. Nonetheless, with what we're seeing in our experience, I'm urging everyone to get a blood vitamin D level.

Don't believe your LDL cholesterol!

14. May 2006 William Davis (0)
Harry's case is typical. For years, his doctor told him his LDL cholesterol of 123 mg was okay. But a heart scan score of 490 (90th percentile at age 52) made him question just where his coronary plaque came from.

Lipoprotein analysis told a very different story: His LDL particle number was 2400 nmol, meaning his trueLDL was more like 240 mg, nearly double the value of LDL obtained through his doctor. Harry had other sources of risk, too, but the LDL particle number was a clear stand-out.

Why does this happen? How can LDL cholesterol be so terribly inaccurate?

LDL cholesterols obtained in virtually all labs are not measured, they're calculated. The calculation was developed in the 1960s by Dr. Friedewald at the National Institutes of Health and therefore goes by his name (the Friedewald calculation). Dr. Friedewald derived this simple calculation to permit doctors across the U.S. to obtain LDL cholesterols, which were technically difficult to measure in those days by using measured HDL, total cholesterol and triglycerides.

Doctors were told that the only time that the Friedewald calculated LDL was inaccurate was when triglycerides exceeded 400 mg. So most family practitioners and internists still believe that calculated LDL's are, for the most part, quite accurate.

Nothing could be further from the truth. When LDL's are actually meaured, you find that LDL is rarely accurate. In fact, in our experience, inaccuracy of 30-50% is the rule, sometimes 100%. The one telltale hint that calculated LDL is wrong is when HDL is <50 mg--that's nearly everybody.

So what's your LDL? You won't really know unless it's measured. Our preferred method is NMR (LipoScience) LDL particle number, probably the most accurate of all. Second best: apoprotein B, direct measured LDL, and non-HDL. (We'll cover this issue much more extensively in an upcoming report on the www.cureality.com website in an extensive Special Report.)

Are you the exception?

14. May 2006 William Davis (0)

I read about 40 heart scans this morning. In the stack was a 41-year old man with a heart scan score of 841.

That's terribly high for anyone, let alone a 41-year old person. He's lucky to find out about this before catastrophe strikes.

People like this worry me. In general, we advise men to consider a heart scan age 40 and older; women 50 and older. If there's anything exceptional about your family history or your own history, then you might notch these numbers down another 5-10 years. For instance, if your Dad had a heart attack at age 43, you might consider a scan at age 35. Or, if you've had diabetes for several years and you're a 42-year old woman, you might think about a scan. (Men tend to develop measurable plaque by heart scans 10 years before women.)

There are no hard and fast rules. It's unusual for a male to have a score >0 before age 40. Likewise, it's very uncommon for a woman to have a score >0 before age 50. But there are occasional exceptions--but they can be very important exceptions.

Our 41-year old man with the score of 841, for instance, probably had a high score since his mid-30s. I've seen several women without any obvious risk factors with scores in the several hundred range in their early 40s.

My rule: When in doubt, opt for safety. Every day, I still read about people in their 30s, 40s, and 50s dying of heart attacks. It shouldn't happen.

When in doubt, get the heart scan. The most you'll lose is the cost of the scan and a modest exposure to radiation. If your score is zero, you know you're safe for the next 5 or more years. But if you have an exceptional score at a young age, take preventive action.

Self-empowerment in health: The new wave in health care

12. May 2006 William Davis (0)
Track Your Plaque is just one facet of the broad and powerful emerging wave of self-empowerment in health.

Hospitals, drug and device manufacturers, and the medical establishment don't like this idea. People managing their own health? That's ridiculous! Dangerous! But mostly unprofitable.

Self-empowerment means having easy access to simple, safe, and inexpensive diagnostic tests like heart scans, carotid scans, bone densitometry (for osteoporosis), cholesterol tests, abdominal ultrasound, even brain scans (e.g., CT or MRI) for people with a family history of brain aneurysm.

Opponents of this idea worry about the "false-positives" that come about with broad testing, i.e, detection of abnormalities that are artifactual. Our experience is that false-positives are only an occasional problem with any test. Instead, we find that most people have many true-positives. In CT heart scanning, for example, we find many unsuspected enlarged aortas (potential future aneurysms), valve disorders, and aortic calcium. These are all important in a preventive program. Unfortunately, your doctor's definition of false-positive often means that no corrective procedure or operation is required.

Other evidence that self-empowerment in health is growing:

--The nutritional supplement movement. What better example of power in managing your own health is there than the fabulous array of nutritional supplements available?

--Medications moving to over-the-counter status. Gradually, more and more medications are trickling into availability for you to obtain without a doctor's prescription.

--What I call "retail imaging", i.e. screening ultrasound, heart scans, full body scans, etc. that are available in most states without a doctor's order.

--The Internet. The rapidity and depth of information available on the Internet today is mind-boggling. It will fuel the self-empowerment movement by providing sophisticated information to the health care consumer previously available only through your physician.

--High-deductible health insurance plans. If health care consumers will bear more and more of the costs of health care, they will seize greater responsibility for early identification and prevention to minimize long-term costs.

There are more. But the movement is powerful and broad--and unstoppable. Let the establishment with vested interests in preserving the status quo fuss and complain, just like horse and buggy manufacturers did in the early 1900's when the autmobile came along.

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.

The Heart.org online debate

20. November 2007 William Davis (9)
There's a fascinating and vigorous debate going on at the Heart.org website among Dr. Melissa Shirley-Walton, the recently publicized proponent of "a cath lab on every corner": Dr. William Blanchet, a physician in northern Colorado; and a Track Your Plaque Member who calls himself John Q. Public.

John Q. has been trying to educate the docs about the Track Your Plaque program. Unfortunately, Dr. Shirley-Walton essentially pooh-poohs his comments, preferring to lament her heavy work load. In her last post, when she discovered that John Q. was not a physician, she threatened to block his posts and delete all prior posts.

However, Dr. Blanchet has emerged as a champion of heart scanning, intensive lipid management, and lipoproteins, much similar to our program. In fact, many of Dr. Blanchet's comments were so similar to mine that John Q. asked me if it was really me! (It is definitely not.)


Here's a sampling of some of the discussion going on now:


Dr. Blanchett started out the discussion by saying:

Stent Insanity
I have no trouble agreeing with the argument that we have initiated the widespread use of DES without adequate study regarding outcomes. Shame on us.

That said, we are ingoring the DATA that shows that most heart attacks occur as a result of non-obstructing plaque and all the talk about which stent to use ignors the majority of individuals at risk. In addition, for a decade we have known that stenting does not improve net outcomes anyway.

What ever happened to effective primary prevention? We discarded EBT calcium imaging like moldy cabbage without even looking at the outcomes DATA. With direction provided by EBT calcium imaging and effective primary prevention, I have been able to reduce myocardial infarction by 90% in my very large Internal Medicine practice. Through effectively identifying patients at risk and measuring success or failure of treatment with serial EBT, I have made the argument as to which stent to use moot. No symptomatic angina and rare infracts equals little need for any stent.

Is anybody listening? Certainly not the cardiologists whose wealth and fortunes are based on nuclaer imaging, angiography and stenting.


Dr. Shirley-Walton, skeptical of Dr. Blanchet's claim of >90% reduction of heart attacks using a prevention program starting with a heart scan:

To rely soley upon a calcium score will deprive you of a lot of information that could be otherwise helpful in the management of your patients.

Without seeming sarcastic, I must refute : "of 6,000 patients I've seen 4 heart attacks in 3 years". Although I certainly hope your statistics are accurate, I will suggest the following:

You've not seen all of the heart attacks since up to 30% of all heart attacks are clinically silent. So unless you are echo'ing or nuclear testing all of these patients in close followup, you aren't certain of your stats.

Secondly, in order to attribute this success to your therapy, you would have to have nearly 100% compliance. In the general population, compliance is often less than 50% with any regimen in any given year of treatment. If you can tell us how you've achieved this level of compliance, we could all take a lesson.



Dr. Blanchett, commenting on his use of heart scanning as a primary care physician:

CAC [coronary artery calcium] is an inexpensive and low radiation exam to identify who is at increased risk for heart attacks.

A study of 222 non-diabetic patients admitted with their first MI found 75% of them did not qualify for cholesterol modifying therapy prior to their initial MI (JACC 2003:41 1475-9). In another study of 87,000 men with heart attacks, 62% had 0 or 1 major risk factors (Khot, et al. JAMA. 2003). Almost all individuals with 0 or 1 risk factor are Framingham "Low risk" and therefore will not qualify for cholesterol lowering therapies. (JAMA. 2001;285:2486-2497)

Risk factors alone are not sufficient. In my practice, of the last 4 patients who have died from heart attacks, none qualified for preventive therapies by NCEP guidelines.

Studies have shown that CAC by EBT provides an independent and incremental predictor of heart attack risk. (1. Kondos et al, Circulation 2003;107:2571-2176, 2. Am Heart J 141. 378-382, 2001, 3. St Francis Heart Study Journal of the American College of Cardiology July, 2005) The old saw that CAC simply reflects risk factors and age is just wrong.

Although CT angiography shows great promise to reduce unnecessary conventional angiography and is helpful in emergency room chest pain evaluation, I do not see CT angiography as a screening study in asymptomatic individuals. 10 times more radiation than EBT calcium imaging plus the risk of IV dye exposure makes CT angiography inconsistent with the principles of a screening test. Taken in the context of a primary care physician's evaluation of heart attack risk, EBT calcium imaging has great value.

Coronary calcium changes management by: 1. Identifying those at risk who do not show up with standard risk stratification (St Francis Heart Study: Journal of the American College of Cardiology July, 2005). 2. Motivating patients to be compliant with therapies (Atherosclerosis 2006; 185:394-399). 3. By measuring serial calcium, we can see who is and who is not responding to our initial treatment so that we can further refine our therapeutic goals (Atherosclerosis, 2004;24:1272).

When used in the primary care preventive setting, CAC imaging is indeed of great incremental value. In my practice, in improves my outcomes so greatly that it compels Melissa Walton-Shirley to question my veracity.


Dr. Melissa Walton-Shirley:

Ahhhhhh.......the aroma of profit making, I thought I smelled it. [Accusing Dr. Blanchett of referring patients for heart scans for personal profit.]

I will tell you that I was a little hurt when I was called "a typical cardiologist with a butcher block mentality" after my primary pci piece for med-gen Med was reviewed by the track your placque [sic] folks.

Though, it's clear that they misunderstood and thought I was cathing for dollars, instead my intention was to "push" for primary PCI for AMI, it left me seething until the blessing of a busy schedule and a forgetful post menopausal brain took its toll.
None the less, an honest open discussion is always welcome here but I would appreciate it if everyone would just divulge their affiliations up front so that the context of their opinions could be better understood.

I also insist that the compliance described by you William B. is rather astounding and a bit unbelieveable, however if it's accurate, you are to be congratulated.



Dr. Blanchett, in response to Dr. Shirley-Walton's statement that she relies on stress testing:

I think that the threshold of comfort you get from stress test stratification is different than what I consider acceptable. It is hard for me to tell a bereaved spouse that the departed did everything I suggested and still died from a MI. Coronary calcium imaging provides me the tool that I need.

Are you aware that there are a number of studies that show a dramatic increase in risk of MI in individuals with an annualized increase in calcified plaque burden of >14%? I consider this to be a valuable measure of inadequacy of medical management. A stress test does not become positive until we have catastrophically failed in medical management. Consequently, even in the patient with “high risk” stratification, one can justify a calcium score to establish a baseline to measure adequacy of primary prevention. Calcium scores by EBT cost about 1/5th the cost of a nuclear stress test and subject the patient to 1/10th the radiation of nuclear imaging and provides more precise information.

Regarding John Q, I do not think that non-medical prospective should be excluded from this blog. I think we as physicians benefit from hearing how the non-physician public views medicine. I have become much better at what I do by listening to my patients and learning from them.


Dr. Blanchett continues:

Yes, I have seen a dramatic reduction in coronary events. Of 6,000 active patients, 48% being Medicare age and over, I have seen 4 heart attacks over the last 3+ years. 2 in 85 year old diabetics undergoing cancer surgery, one in a 90 year old with known disease and one in a 69 year old with no risk factors, who was healthy, and had never benefited from a heart scan.

The problem with coronary disease is that we rely on risk factors. Khot et al in JAMA 2003 showed that of 87,000 men with heart attacks, 62% had 0 or 1 major risk factor prior to their MI. According to ATP-III, almost everyone with 0-1 risk facto is low risk and most are do not qualify for preventive treatment. EBT calcium imaging could have identify 98% of these individuals as being at risk before their heart attack and treatment could be initiated to prevent their MI.

Treating to NCEP cholesterol goals prevents 30-40% of heart attacks. Treating to a goal of coronary calcium stability prevents 90% of heart attacks. Where I went to school a 40% was an F. Why are we defending this result instead of striving to improve upon it? I am not making this up, look at Raggi's study in Ateriosclerosis, Thrombosis, and Vascular Biology 2004;24:1272, or Budoff Am J Card

Melissa, I strongly disagree with the assertion that the stress test is a great risk stratifier. Laukkanen et al JACC 2001 studied 1,769 asymptomatic men with stress tests. Although failing the stress test resulted in an increased risk of future heart attack, 83% of the total heart attacks over the next 10 years occurred in those men who passed the stress test.
Falk E, Shah PK, Fuster V Circulation 1995;92:657-671 demonstrated that 86% of heart attacks occur in vessels with less than 70% as the maximum obstruction. A vast majority of patients with less than 70% vessel obstruction will pass thier stress test.

William, regarding your question of owning or referring for EBT imaging, I would be amused if it were not insulting. The mistake that is often made is that EBT imaging is a wildly profitable technology. It is not nearly as profitable as nuclear stress imaging. Indeed there are few EBT centers in the country that are as profitable as any random cardiologists stress lab.

How can we justify not screening asymptomatic patients? Most heart attacks occur in patients with no prior symptoms and according to Steve Nissen, 150,000 Americans die each year from their first symptom of heart disease. My daughter is at this moment visiting with a friend who lost her father a few years ago to his first symptom of heart disease when she was 8 years old. That is not OK! We screen asymptomatic women for breast cancer risk. Women are 8 times more likely to die from heart disease than breast cancer. We do mass screening for colon cancer and we are over 10 times more likely to die from heart attacks than colon cancer. An EBT heart scan costs 1/8th the cost of a colonoscopy.

So what say we drop the sarcasm and look at this technology objectively. Read the literature, not just the editorial comments. This really does provide incredibly valuable information that saves lives.

Yes, a 90% reduction in heart attacks in my patients compared to the care I could provide 5 years ago when I was doing a lot of stress testing and referring for revascularization. Much better statistics than expected national or regional norms. I welcome your scrutiny.


John Q. Public jumps into the fray with:

Fascinating, isn't it, that there appear to be two doctors, William Blanchet in this forum and Dr. William Davis, FACC, of cureality.com that both claim to have dramatically reduced risk of heart attack among their patients and/or actual calcium plaque score regression and BOTH are ardent proponents of CT Calcium Scoring?


Despite Dr. Blanchet's persuasive arguments backed up with numerous scientific citations and John Q.'s support, I sense they had no effect whatsoever on Shirley-Walton's way of thinking.

Such are the deeply-entrenched habits of the cardiology community. It will be many years and impassioned pleas to see things in a different light before the wave of change seizes hold.

To learn how to eat . . . try fasting

18. November 2007 William Davis (13)
Curious thing about fasting: It teaches you how to eat.

In previous posts, I've discussed the potential benefits of fasting: reduction of blood pressure, reduction of inflammatory responses, drop in blood sugar, weight loss, and reduced heart attack risk. In my recent Heart Scan Blog post, Fasting and Heart Disease, I discussed the just-released results of a study in people who fast for religious reasons and experience less heart disease.

Fasting can mean going entirely without food and just making do with (plenty of) water, or it can mean variations on "fasting" such as vegetable juice fasts, soy milk fasts, etc.

How can fasting teach you any lessons about food and eating?

People who fast will tell you that the experience:

--Helps you appreciate food tastes when you resume eating. After a fast, flavors are stronger; sensations like sweet, sweet, or salty are sharper; you become reacquainted with the variety of wonderful food textures.

--Makes you realize how you ate too much before your fast. After a fast, you are satisfied with less. You will eat more for taste and enjoyment, less for satiety and mindless indulgence.

--Makes you more mindful of the act of eating. For many of us, eating is an automatic activity that provides fleeting satisfaction. After a fast, each bite of food brings its own special enjoyment.

--Reveals to you how awful you felt when many foods were eaten. For example, many people are physically slightly ill after eating pancakes, pizza, or other highly processed foods but cease to recognize it. Remove the offensive foods entirely and you might realize just how bad you felt.

--Takes away fear of hunger. Many people have a gut-wrenching fear of hunger. It's probably partly instinctive, that animal-like fear of not knowing when your next meal is coming, partly the abnormal, artificial drive to eat ignited by processed foods like wheat and corn syrup.

--Makes you realize just how much of your day is spent in some activity associated with food. Shopping, eating, cleaning up afterwards, thinking and talking about food all occupy an extraordinary portion of everyone's life. A fast can open your eyes to just how much time is spent in these pursuits. Sometimes, gaining an awareness of a mindless, repetitive behavior can provide the first step towards changing direction.


Most people consider a fast for rapid weight loss. But fasting is far more than that. Perhaps fasting has become an integral part of many religious practices because of its capacity for enlightenment, reawakening, revelation, but not of only the spiritual, but also of how far many of us have strayed in diet.

Fasting is what Omnivore's Dilemma author Michael Pollen might describe as looking the pig you're about to eat in the eye, an opportunity to open your eyes to what it is you 've been doing all these years.

Don't be satisfied with "deceleration"

16. November 2007 William Davis (2)
In the Track Your Plaque program, we aim to stop or reduce your heart scan score.

Recall that, without any preventive efforts, heart scan scores can be expected to increase at the average rate of 30% per year (faster at lower scores, slower at higher scores by a quirk of arithmetic).

I am continually surprised at how often people--that is, people not in the Track Your Plaque program--are often content with what I term "deceleration," or the slowing of plaque growth. In truth, most people are content with deceleration of plaque growth because they simply don't know that plaque continues to grow.

For instance, the BELLES Trial (Beyond Endorsed Lipid Lowering with EBT Scanning (BELLES)), reported in 2005 showed that 650 women participants continued to increase heart scan scores 15% whether they took "high-intensity" statin therapy in the form of Lipitor 80 mg or "low-intensity" statin therapy as pravastatin 40 mg, even though the group taking Lipitor experienced twice the amount of LDL reduction. In other words, heart scan scores continued to increase at the same rate of 15% per year regardless of the intensity of LDL lowering by statin drug.

Another study reported in 2006, Effect of intensive versus standard lipid-lowering treatment with atorvastatin on the progression of calcified coronary atherosclerosis over 12 months: a multicenter, randomized, double-blind trial reported similar results. Of the 471 participants, those taking Lipitor 80 mg per day experienced 27% per year plaque growth (LDL cholesterol 87 mg/dl); those taking 10 mg Lipitor experienced 25% plaque growth (LDL 107 mg/dl). The intensity of statin therapy made no difference on the rate of plaque growth.

In other words, if we are content to sit back and take Lipitor or other statin drug, follow the conventional American Heart Association low-fat, low-cholesterol diet, we will experience somewhere between 15 to 27% annual plaque growth--year after year.

No wonder that conventional advice offered by your friendly neighborhood doctor will avoid (postpone?) only one heart attack in four.

Such is the nature of coronary plaque deceleration: growth is modestly slowed, but is not stopped. Nor is it reversed.

In the Track Your Plaque program, we grade deceleration of plaque growth into three distinct stages out of a total of five. (See Winning Your Personal War with Heart Disease: The Track Your Plaque 5 Stages of Success.)

Why be satisfied with deceleration? Why not aim for a total stop to plaque growth? Why not aim for stage 5 of Track Your Plaque success: reversal?

Whole grains and half truths

14. November 2007 William Davis (13)
(For followers of the Heart Scan Blog, below is a re-posting of a recent post. I've moved it up to make it accessible to a number of patients that I asked to look at this post for some conversation about the concept of wheat-free diets.)


TV ads, media conversations, magazine articles, even advice from the American Heart Association and USDA (a la Food Pyramid) all agree: eat more whole grains, get more fiber.

What happens when you follow this advice to add more and more whole grains to your diet? Look around you: People gain weight, they become pre-diabetic and diabetic. Lipids and lipoprotein patterns emerge: increased triglycerides and VLDL, reduced HDL, small LDL. Blood sugar goes up, inflammatory responses are ignited. You feel crumby, cancer risk is increased.

"Official" agencies have urged us to eat more grains, get more fiber and most Americans have complied. We now have a nationwide health disaster that will eventually lead to more people with coronary plaque, more heart disease, more heart attack, more heart procedures.

This is why I've been urging patients to go wheat-free. It has proven an extraordinarily and surprisingly effective strategy for:

1) rapid and profound weight loss
2) raising HDL and reducing triglycerides, VLDL, and small LDL
3) reducing blood sugars, pre-diabetes and diabetes

So here I (re-) post just a sampling of the comments sent by readers of the Heart Scan Blog who have given this idea a try.

It's true! We've done it. My husband and I stopped eating all grains and sugar in February. At this point, we really don't miss them any more. It was a huge change, but it's worth the effort. I've lost over 20 pounds (10 to go)and my husband has lost 45 pounds (20 to go). On top of it, our body shapes have changed drastically. It is really amazing. I've got my waist back (and a whole wardrobe of clothes) - I'm thrilled.

I'm also very happy to be eating foods that I always loved like eggs, avocados, and meats - without feeling guilty that they're not good for me.

With the extremely hot weather this week in our area, we thought we'd "treat" ourselves to small ice cream cones. To our surprise, it wasn't that much of a treat. Didn't even taste as good as we'd anticipated. I know I would have been much more satisfied with a snack of smoked salmon with fresh dill, capers, chopped onion and drizzled with lemon juice.

Aside from weight changes, we both feel so much better in general - feel much more alert and move around with much greater flexibility, sleep well, never have any indigestion. We're really enjoying this. It's like feeling younger.

It's not a diet for us. This will be the way we eat from now on. Actually, we think our food has become more interesting and varied since giving up all the "white stuff". I guess we felt compelled to get a little more creative.

Eating out (or at other peoples' places) has probably been the hardest part of this adjustment. But now we're getting pretty comfortable saying what we won't eat. I'm starting to enjoy the reactions it produces.


Weight loss, increased energy, less abdominal bloating, better sleep--I've seen it many times, as well.

I was a victim of the '80s lowfat diet craze - doc told me I was obese, gave me the Standard American Diet and said to watch my fat (I'm not a big meat eater, didn't like mayo ... couldn't figure out where my fat was coming from! maybe the fries - I will admit I liked fries). I looked to the USDA food pyramid and to increase my fiber for the constipation I was experiencing. Bread with 3 grams of fiber wasn't good enough; I turned to Kashi cereals for 11 years. My constipation turned to steattorrhea and a celiac disease diagnosis! *No gut pains!* My PCP sent me to the gastroenterologist for a colonscopy because my ferritin was a 5 (20 is low range). Good thing I googled around and asked him to do an endoscopy or I'd be a zombie by now.

My symptoms were depression & anxiety, eczema, GERD, hypothyroidism, mild dizziness, tripping, Alzheimer's-like memory problems, insomnia, heart palpitations, fibromyalgia, worsening eyesight, mild cardiomyopathy, to name a few.

After six months gluten-free, I asked my gastroenterologist about feeling full early ... he said he didn't know what I was talking about! *shrug*

But *I* knew -- it was the gluten/starches! My satiety level has totally changed, and for the first time in my life I feel NORMAL!


Feeling satisfied with less is a prominent effect in my experience, too. You need to eat less, you're driven to snack less, less likely to give in to those evil little bedtime or middle-of-the-night impulses that make you feel ashamed and guilty.



An anonymous (female) commenter said:

My life changed when I cut not only all wheat, but all grains from my diet.

For the first time in my life, I was no longer hungry -no hunger pangs between meals; no overwhelming desire to snack. Now I eat at mealtimes without even thinking about food in between.

I've dropped 70 pounds, effortlessly, come off high blood pressure meds and control my blood sugar without medication.

I don't know whether it was just the elimination of grain, especially wheat, or whether it was a combination of grain elimnation along with a number of other changes, but I do know that mere reduction of grain consumption still left me hungry. It wasn't until I elimnated it that the overwhelming redution in appetite kicked in.

As a former wheat-addicted vegetarian, who thought she was eating healthily according to all the expert advice out there at the time, I can only shake my head at how mistaken I was.


That may be a record for me: 70 lbs!!

It's worth it and you won't look back!

Many things will improve, not just weight reduction: you will think clearer, your reflexes will improve, your breathing rate will go down, your blood pressure will normalize. You will never or rarely have a fever or viral infections like cold or flu. You will become more resistant to cold temperature and you will rarely feel tired, ever!

Whenever I go out to breakfast I look around and I am in shock at what people eat for breakfast. Big stack of pancakes, fruit, fruit juice syrup, just like you said. This is not breakfast, this is dessert ! It has the same sugar and nutrition as a birthday cake, would anyone think cake is ok for breakfast ? No, but that is exactly the equivalent of what they are eating. Somehow we have been duped to think this is ok. For me, I typically eat an omelette when I go out, low carb and no sugar. I dont eat wheat but invariably it comes with the meal and I try to tell the waitress no thanks, they are stunned. They try to push some other type of wheat or sugar product on me instead, finally I have to tell them I dont eat wheat and they are doubly stunned. They cant comprehend it. We have a long way to go in terms of re-education.

Yes. Don't be surprised at the incomprehension, the rolled eyes, even the anger that can sometimes result. Imagine that told you that the food you've come to rely on and love is killing you!

I was overweight by only about 15lbs and I was having pitting edema in my legs and shortness of breath. My cardiologist and I were discussing the possible need of an angiogram. I was three years out from heart bypass surgery.

Before we could schedule the procedure, I tested positive for gluten sensitivity through www.enterolab.com. I eliminated not only wheat but also barley and rye and oats(very contaminated with wheat) from my diet. Within a few weeks my edema was gone, my energy was up and I was no longer short of breath. I lost about 10 lbs. The main reason I gave up gluten was to see if I could stop the progression of my peripheral neuropathy. Getting off wheat and other gluten grains has given me back my life. I have been gluten free for 4 years and feel younger than I have in many years.

There are many gluten free processed foods, but I have found I feel my best when I stick with whole foods.


Ann has a different reason (gluten enteropathy, or celiac disease) for wanting to be wheat-free. But I've seen similar improvements that go beyond just relief of the symptoms attributable to the inflammatory intestinal effects of gluten elimination.

I have relatively successfully cut carbs and grains from my diet thus far.

Because I've got some weight to lose, I have tried to keep the carb count low and I've lost 15 pounds since then.

I have also been very surprised at the significant reduction in my appetite. I've read about the experience of others with regard to appetite reduction and couldn't really imagine that it could happen for me too. But it has.

A few weeks ago, I attended a party catered by one of my favorite italian restaurants and got myself offtrack for two days. Then it took me a couple of days to get back on track because my appetite returned.

Check out Jimmy Moore's website for lots of ideas about variations of foods to try. The latest thing I picked up from Jimmy is the good old-fashioned hard boiled egg. Two or three eggs with some spicy hot sauce for breakfast and a handful of almonds mid-morning plus a couple glasses of water and I'm good for the morning no problem.

I find myself thinking about lunch not because I'm really hungry but out of habit.

The cool thing too now is that the more I do this, the more I'm just not tempted much to do anything but this diet.


Going wheat-free, along with a reduction in processed sugary foods like Hawaiian Punch, sodas, and candy, is the straightest, most direct path I know of to lose weight, obtain all the health benefits listed by our commenters, as well as achieve the lipoprotein corrections we seek, like reduction of small LDL particles and rise in HDL, in the Track Your Plaque program.

Fasting and heart disease

14. November 2007 William Davis (10)
Followers of the Track Your Plaque program know that we advocate periodic fasts to reduce heart disease risk.

I came across an interesting report form an abstract presented at last week's American Heart Association meetings in Orlando:

(Read the report at HeartWire. You will need to register or sign-in.)

In this study, the investigators tried to determine why members of the Church of Jesus Christ of Latter-Day Saints (LDS) tended to have reduced risk of heart disease compared to others in the area but not in the LDS faith. While the reduced risk of heart disease in LDS members had been traditionally attributed to the no smoking policy advocated by the Mormon church, the investigators suspected that there was more to the reduced risk.

Of 515 people interviewed, periodic fasting, whether for religious or other reasons, was found to distinguish people who were less likely to have coronary disease by conventional catheterization (59% vs. 67%). (Since the study was published in only abstract form, it's not clear why all these people underwent heart catheterization in the first place.)

Nonetheless, it's an interesting observation and one consistent with the benefits we see when someone fasts: reduced blood pressure, reduced inflammatory responses, improved lipids and lipoproteins, weight loss.

Fasting can be an especially effective method to gain control over heart disease and coronary plaque if rapid control is desired. In fact, I wonder if the normally year-long process of plaque control that I advocate can be much abbreviated. Fasting, I believe, is a crucial component of rapid control, what I've talked about in Instant Heart Disease Reversal

There's also additional thoughts on fasting in my Heart Scan Blog post, For rapid success, try the "fast" track.

Fasting is not something to fear. It can be an enlightening process that can serve to abruptly sever bad habits, perhaps even turn the clock back on prior dietary and lifestyle excesses. My favorite variation on fasting is to use soy milk (yes, yes, I know! I can already hear the the soy bashers screaming!) as a meal substitute. It is an easy, less dramatic way that still maintains most of the benefit of a full, water-only fast.

Coronary arteries aren't what they seem

12. November 2007 William Davis (5)
Why do stress tests so often fail to detect coronary atherosclerotic plaque? Why do even heart catheterizations--the "gold standard"--fail to disclose the full extent of plaque within the walls of coronary arteries?

We owe much of the explanation of these phenomena to Dr. Seymour Glagov, retired professor of pathology at the University of Chicago.



When studying the coronary arteries of people who died, he observed that people commonly had plenty of atherosclerotic plaque lining the artery wall, yet it did not necessarily impinge on the artery "lumen," or the internal path for blood to flow.

The only time the lumen became obstructed by plaque was when either 1) plaque grew to overwhelming levels and was severe and extensive, or 2) when a plaque had "ruptured," meaning its thin covering had been penetrated and eroded by the underlying plaque tissue like a volcano emerging from the surface and erupting.

This groundbreaking observation, now dubbed "the Glagov phenomenon," explains why someone can have a normal stress test on Tuesday but erupt a plaque on Wednesday.

The Glagov phenomenon also explains why heart scans can detect plaque when both stress tests and heart catheterizations fail to do so. Many physicians will then interpret this to mean that the heart scan was wrong. With the Glagov phenomenon in mind, you can see that the heart scan is not wrong, it is simply detecting coronary atherosclerotic plaque at a stage that is not yet detectable by the other methods.

In the illustration, you can see that the lumen of the vessel is maintained--despite the artery on the left having minimal plaque, the artery on the right containing moderate plaque. If either artery were examined by a test that relies on blood flow--stress test or heart catheterization--both would appear normal. But a test that examines the artery wall, such as a heart scan, would readily detect the artery on the right and probably even the artery on the left.




I am very grateful to Dr. Glagov and his insight into this important process. Otherwise, we might still be floundering around trying to understand the apparent discrepances between these tests that simply provide different perspectives on the same problem.
