LCHF 15 years, Coronary Artery Calcium Score ZERO!

Let’s talk about an important cardiovascular (CV) endpoint, specifically atherosclerosis or plaque, that usually appears before ever having a heart attack, stroke or sudden cardiac death. This is the case of a 54 year old male who’s been on a whole foods, low carb high fat diet for over 15 years.  Because his lipid profile and all biomarkers had improved, he decided it was time for a heart scan to see if this matched the biomarkers. It turns out the result was a perfect calcium score of ZERO! You may know this man, as he’s yours truly Dr. Jeff Gerber and is not to be confused with that ‘Lobby Boy‘ from the Grand Budapest! 😛 Have a look at these beautiful images:

Vascular imaging of any kind provides invaluable information relating to CV risk. Atherosclerosis, plaque (hardening of the arteries) or inflammation of the arteries is the new endpoint and visualizing plaque’s presence or not using tools like coronary artery calcium scoring can provide powerful and useful information that will motivate individuals to make change.

Normal, non-inflamed arteries do not contain calcium. As plaque develops (first soft plaque, then hard), calcium builds within the inflamed blood vessel wall, and this can be detected using high speed computerized tomography (CT) imaging. Although no test is perfect and radiation exposure (equivalent to a mammogram or slightly greater) is an important consideration, coronary artery calcium scoring is a great direct method to estimate plaque burden and cardiac risk. The more calcium that you have (especially if you’re in the unlucky ≥75th percentile for age and sex), along with calcium progression (≥15% per year,) the greater your risk. Even with a positive calcium score, stabilizing that score greatly reduces your risk.

Calcium Score Presence of Plaque
0 No evidence of plaque
1-10 Minimal evidence of plaque
11-100 Mild evidence of plaque
101-400 Moderate evidence of plaque
>400 Extensive evidence of plaque

Adapted from Rumberger JA et al. Mayo Clinic Proceedings March 1999: 74:243-252

To illustrate, with a score of zero your likelihood of having a cardiac event is <1% yearly compared to a high score of >300 making you at least 8 times more likely to suffer from a cardiac event. Progression of ≥15% per year for any given score is particularly ominous as this can cause one to be 17.2 times more likely to have a cardiac event and 3 times more likely to die from any cause. Halting progression is most imperative and will greatly reduce risk.

Calcium Score Risk Equivalent 10-Year Event Rate, %
0 Very low 1.1-1.7
1-100 Low 2.3-5.9
101-400 Intermediate 12.8-16.4
>400 High 22.5-28.6
>1000 Very high 37

What’s really important is that calcium scoring actually surpasses Framingham risk assessment that traditionally uses age, sex, cholesterol, HTN, smoking, diabetes and history of previous MI to determine risk. Calcium scoring does truly excel at predicting CV risk better than any other non-invasive tool available today.

Vascular ultrasound (performed in our office) is another useful technology to look for plaque burden in larger vessels like the carotids and the aorta. Because coronary arteries (supplying blood to the heart muscle) are relatively small and always in motion, other technologies beyond standard ultrasound had to be developed to properly visualize these small vessels. There are several competing technologies including CT angiogram, heart catherization and intravascular ultrasound, but they are all invasive and expensive relative to CT calcium scoring.

Just to clarify, I don’t own a CT scanner nor do I get compensation to refer people for testing. After further study and peripheral involvement with The Widomaker movie (a must watch) it’s clear to me how powerful and important cardiovascular imaging is especially for anyone who wishes to know their risk.

Regarding proper prevention, it’s different for everyone, but I am not the only one who can boast of a ZERO calcium score while being on a LCHF diet. Jimmy Moore, Ivor Cummins, Gearóid Ó Laoi, and some of our patients are just a few examples of people who have been lucky when it comes to achieving that perfect calcium score of ZERO. Others have been able to stabilize and improve their calcium scores. Certainly there are many factors to consider including genetics, but we have all chosen the low carb high fat dietary approach to address CV risk and health, and so far this approach appears to be working. I find it important to monitor all CV markers when it comes to addressing any lifestyle approach.

Unfortunately, calcium scoring has been underutilized for reasons spelled out in The Widomaker movie and mostly ignored by primary care doctors. I am, however, optimistic that CV imaging will gain momentum in the next several years, thanks to the movie and the various medical institutions that have finally endorsed the test. Most hospitals and other outpatient facilities actually do offer the test. In Denver, Front Range Preventive Imaging is by far my favorite because my trusted colleague, Dr. Bill Blanchet is the medical director. They do calcium scoring testing accurately, reliably and using minimal radiation. What’s difficult is finding the right doctor who knows how to interpret the results and provide proper advice, addressing prevention as it relates to diet, exercise and medication. That’s where our office comes into the equation.

Is Coronary Calcium Scanning The Mammography of the Heart?

Zero CAC Score Confers 15-Year “Warranty” Against CAD related mortality

  • Craig

    There are claims that vitamin K2 can prevent or even reduce calcification of plaque. The heart scan CT picks up the calcium (which is approx 20% of plaque volume) and uses this to determine the calcium score. If something like K2 MK-7 reduces calcium score by removing calcium from the plaque, is it really removing the plaque or just removing the calcium from the plaque leaving the other 80% of the plaque intact just invisible to the CT scanner? So it seems to me that having a reduced calcium score does NOT mean there is not any plaque, just no calcified plaque. Couldn’t one have bunch of uncalcified plaque (because the K2 worked) and have a false sense of security from a good calcium score when in fact they are high risk? I think that’s where the CCTA test comes in because it can see all plaque not just calcified plaques.

  • bonnie

    If you don’t have a zero score , but go on lchf diet can you reduce your score in time or does that score always stay the same even on the lchf diet?

  • Jeanie Miller

    I do have a story and a question. I’m a 62 yr old female. I’ve been on LCHF for 3 years now. Lost 30 lbs. Currently about 20 lbs over weight. I had to select a new Primary Care Giver and after having a full blood panel done he pointed out my LDL Cholesterol was 142. This is about 10 points higher than the previous year. So I told him I’d been LCHF for a few years and drinking Bulletproof Coffee (coffee w/grass fed butter and coconut oil added) and I would cut out the coconut oil and cut back on cheese and come back in 6 weeks. Well when I went back 6 weeks later my LDL had climbed to 166!? I refused his statins and he insisted on a Heart Scan which came back zero. I’ve added all the right foods to my diet to try and lower my LDL and not gain back the weight I lost. My question is If my Calcium Score is Zero is there any need for statins? I have a sluggish thyroid and arthritis, otherwise Im perfectly healthy.

    • Scott Morgan

      Jeanie: No benefit has ever been shown for women taking statins. You should ask your doctor for the basis of your prescription. There is very little correlation between LDL and heart disease. Those with the lowest LDL have the worst outcomes. In terms of odds ratio, the best predictor of heart disease is triglycerides/HDL ratio, and LCHF is by far the best for minimizing that ratio. You should read some of the excellent books on cholesterol: The Great Cholesterol Myth: Why Lowering Your Cholesterol Won’t Prevent Heart Disease-and the Statin-Free Plan That Will by Jonny Bowden and Stephen Sinatra, The Great Cholesterol Con by Malcolm Kendrick, Cholesterol Clarity by Jimmy Moore, and Fat and Cholesterol Don’t Cause Heart Attacks and Statins Are Not The Solution by several authors. All of these are available on Amazon.

    • Amy

      I’ve been eating a zero carb (meat and eggs only) diet for almost 2 years. I am 42, 5’7″, 125 Lbs. I had blood work done in Dec 2015 (9 months after starting ZC). At that time my LDL was around 150, but my HDL was 85 and my trigs were 55. I had an NMR particle test, and I had NO evidence of small dense particles–only large fluffy ones.
      Fast forward to Dec 2016… LDL is now 500 (total chol 600), HDL is 93, trigs are 93 (it’s common for trigs to increase when LDL increases). I had another NMR test….all VERY large fluffy particles this time, still no evidence of small dense particles.
      With perfect NMR results and a trig/HDL ratio at or below 1, I feel very comfortable with my lipid panel. Total cholesterol and even LDL chol is completely irrelevant in assessing cardiac health/risks. Your trig/HDL ratio and particle size is more relevant, as is your coronary calcium score (which I haven’t had done yet). Incidentally, my doctor didn’t even mention statins to me…..she knows I will NEVER take them. High cholesterol is actually associated with longevity in women. I feel very healthy.

      • Jeanie Miller

        Hi Amy, Thanks for sharing. I also have no intention of taking statins. Everything else in my blood work is great, except my D which I have now brought back up. I have recently made a connection between my Thyroid medication and my LDL. I had requested my Dr. replace my Armour thyroid with a synthetic since the Armour has gotten so expensive. Being a by the numbers man he had to fool with it and started lower the dosage each time I came in to have my cholesterol checked. EVERY time he lowered the Synthroid dose my LDL went up 20 points. I pointed this out to him last time I was in and he kind of blew me off. Needless to say I’m on my way to a new doctor next month for a second opinion.

  • Rebecca

    Hello Dr Gerber. First and foremost, I want to thank you and Ivor for sharing all this information. After watching the Widowmaker movie I convinced my doc to order a Calcium test for my husband age 61. My father in-law had quintuple bypass at 70 and his father dropped dead of a heart attack at 55. So on Sept. 15 my husband had the test. His results indicate a calcium score of 16 mild plaque burden and moderate CVD desease risk. The location of the plaque was in the Left Anterior Descending Volume 130 was 12 and AJ-130 was 16. All additional findings for were within normal. My husband eats a relatively low carb diet certainly at home as we have no processed foods, all meat grassfed and organic, I make everything froms scratch including mayo dressings etc. to avoid added sugars. But he does sometimes cheat at work, drinks read wine every night and he definitely has a sweet tooth. My first question to you is why does the report say: “These calcium deposits usually begin to form years before any symptoms develop. Early detection and modification of risk factors such as smoking and cholesterol intake, can slow the progression of coronary disease, Really cholesterol intake? His apolipoprotien E genotype is 3/3 which means he should be able to consume lots of healthy fats like butter, avacados marbled red meat and fatty fish is that correct? His MTHFR isC677T/A1298C for which he takes PoDiaPn. Lab test in march alarmed the doc and she told him to cut the saturated fat because his total cholesterol went from 204 to 243, Additionally his small LDL-P went from 684 to 890. His ApoB-A-1 Ratio (calculated) also went up from .79 to .96. But what the doctor said was so urgent was his Lp-PLA inflammation marker that went from 325 to 390! She told him to cut the fats, red meat, and stick to nuts, avacados and lean meats and fish. By the way he exercises regularly, is very lean and has no abdominal fat, His Glucose was 89, A1C 5.6 and insulin 4, omega 3 was 7.3, ferrtin 60, vitamin D 41.
    Fast forward to July after following the doctor’s advice and numbers look better. Hos total cholesterol is down from 243 to 192, his small LDL-P is down from 890 to 669, his ApoB-ApoA ration is down from .96 to .71 and the inflammation marker Lp-PLA is down from 390 to 355. Fasting glucose down from 89 to 81 A1C down from 5.6 to 5.3 and insulin was 2!! His ferritin is still 60 his vitamin D went up from 40 to 49 but his omega 3’s went down a bit from 7.8 to 7.3, So here is my next question did cutting the saturated fat really help that much in particular with the inflammation or could it have been something else. Moving forward what should he be doing to reverse the calcium score or at the very least maintain it where it is? He doesn’t like taking many supplements but I have tried to explain that certain supplements are essential as you age because your body just is not that efficient at producing those things, So basically if you had to recommend a few supplements and steps to take to help further lowering his risk of CVD what would they be?

    • @Beca123:disqus A Volume 130 was 12 and AJ-130 was 16 is not such a bad score. And yes it’s historical as it takes years do build up calcium and plaque. I would check a score in another 2-3 years and see if all that your husband is doing will stabilize his score. A diet addressing inflammation and oxidative stress such as low carb, Vit D3, K2, Magnesium and artisan salt.

      • Rebecca

        Thank you Dr Gerber, I will share your response with him and hopefully he will pay more attention to inflammation and oxidative stress.

    Magnesium is also a very important mineral, which is a calcium antagonist. They balance each other, and most all of us are deficient in magnesium. The mainstream pushes calcium like candy, neglecting the very important magnesium.
    But great to see your scan after being on a high fat, low carb diet for 15 years! I am doing the same, but not for so long.

  • Mark

    I am nearly 53 and follow a daily healthy diet and life style. I have had all my blood tests done religiously each of the previous 10 years and currently have a LDL of 2.5 and HDL of 1.5 with excellent liver function etc. I exercise both by cycle and weight program nearly daily. My BMI is normal, my blood pressure is 80/120 and I do not believe I suffer from stress. I have never had any symptoms of heart disease even during 10 to 21 km jogs or 120 km cycle rides. My father had both a stent and eventually a triple bypass in his 60’s and died from a stroke at 71.
    Recently I have found my calcium score is 2400 (LM 0.0, LAD 368, LCX 404 & RCA 1536). I have since had a stress test to a heart rate of 158 (after riding 13 kms to clinic). The report was blood pressure and heart operation normal. I have had an ECG which noted an extremely dilated Left atrial of 51 ml/m vs normal 29 ml/m with all other areas normal. I have also had a scan of my left and right carotid arteries which was reported as “no significant stenoses identified”. My cardiologist has put me on a stantin and daily aspirin and advised me to continue my daily exercise activities and “don’t change my life”.
    I am happy with my very experienced Cardiologist, but I am interested in anyone else with similar conditions as I appear to be outside all other of the key causes i.e. obese, diabetic, smoker, high blood press high cholesterol and inactivity.
    Can anyone advise of other treatments or any ability to reverse the plaque build-up.
    Thanks Mark

    • Hi Mark. The goal would be to stabilize your plaque, regression is not typical. Although your way above the 90th percentile for total score, keeping the progression of calcium <15%/yr will greatly increase your odds. Certainly there are genetic factors to consider, but your healthy lifestyle and perhaps collateral circulation has been helping. I would stick to a diet that addresses inflammation and oxidative stress. Grains, sugars and the industrial vegetable oils are especially bad. Get another scan in a few years.

    • David Go here and read, read, read. Although Dr. Gerber is correct that regression is not typical, it is for reasons that you will learn by doing research. You can easily reverse you artierial plaque. I am on this therapy, more or less. I’m not sure which scoring system was used on you, but my score was 71. At my age (almost 53) that puts me at higher risk than normal, for my age. I was already 8 months into my own prescribed treatment plan before I found out about the product he sells and had my first scoring done. My score before my teatment plan might well have been much higher. I may go for another scan at 6 month interval, or wait until a full year. I expect to have much lower numbers. For you to have a score of 0 on your left main is odd based on my own score and reading scores of other scores. Usally I see the left main as having the most buildup. But everybody is different. Good luck.

  • William Blanchet

    We have the ability to take heart disease off of its pedestal as the leading cause of death and disability in this country. Find out what your risk really is with a coronary calcium score and treat until the calcium score stabilizes. This can usually be done with diet, supplements, great dental hygiene, adequate sleep, treatment of BP and diabetes and perhaps a generic medication or two.

  • JDavidP

    I’ve lived right for decades. (As far as what’s been assumed as “living right”.) Mediterranean diet, daily exercise, good sleep, good outlook on life. Not much I can do about age or gender, but everything else on your risk list is fine. Except my total cholesterol has gotten a bit high. I wanted to prove to my cardiologist that I was fine and didn’t need a statin, so I got tests. Passed the stress test with flying colors – better than expectation for age, no ECG abnormality. My hsCRP came back at .5. (Point five.) But then I was quite surprised when my CAC came back with an Agatston total of 1,609. (One thousand six hundred and nine!)
    I have to wonder where that came from. I’m told there MUST be plaque. There’s no other cause for such calcification?

    • @JDavidP:disqus, there are always genetic factors to consider. I allpaud your effort to improve your lifestyle. What’s important is to prevent calcium score progression (<15%)/yr as this will stabilize your risk. Keep On Keepin' On!

      • JDavidP

        But these prospective genetic factors must involve a particular process, no? If I knew the process I’d have a clue as to how to counter it specifically.
        Matrix GLA protein not behaving properly? Some such? I’ve been taking my MK-7.
        What specialty would know about this sort of thing?

        • @JDavidP:disqus We do recommend K2, D3, Magnesium, artisan salts and methylfolate along with proper diet to decrease CV risk. I wish there was more to say about the relation to genetic factors but we’re all still learning. The goal would be to address inflammation and oxidative stress from all angles.

  • Jeanna

    I’m still trying to figure out why at age 50, I have a 0 score! I have high blood pressure, high cholesterol…about 285…high stress life, I have an autoimmune disorder called Hashimotos which makes it virtually IMPOSSIBLE to lose weight (and pls don’t give me friendly advice about how to lose weight or tell me I’m a fatty because I either eat too much or I don’t exercise…I walk a few miles a day, strength train a bit and I am mostly a veggie eater…I’ve also eliminated the following from my diet: soy, chocolate, ALL grains, ALL night shades, caffeine, dairy, etc. I eat mainly veggies, a bit of protein and a couple pieces of low glycemic fruit a day…I’m still a fatty…) so…I don’t understand why it is with all of the issues I have, a calcium score of 0! I am blessed, I suppose. I also have a long line of women on my mothers side who died between the ages of 23 and 56…I’m not that far off. I’m a bit concerned there is soft calcification lurking in my heart, ready to rear its ugly head in a few years…

    • @jeanna, I’m not sure where to start but simply to say that you could get a CT angio if your really worried about soft plaque.

I did the run Sunday, Karate training Monday (and Wednesday), and two light recovery runs 8 Km Tuesday and Thursday. I did all my running training fasted and on water- switch off the gut/parasympathetic/insulin and let the fatty acids/ketones fly!

  • PJkrt

    Another issue for some may be the exposure to radiation from the CT scan. The typical heart scan using 64k-slice technology is supposedly equal to a few thousand chest x-rays. The newest CT-technology is 256k-slice – it supposedly is equal to a 100 chest x-rays.

    If so, that’s a large reduction in radiation exposure. Plus the 256k-slice technology delivers much better resolution. I would assume that means that previously undetected calcification using the old technology can now be detected by this newer technology.

    And it takes less time to do the actual heart scan – it’s faster.

    I am under the impression that not a lot of medical centers have this newer technology yet.

    • I had my test performed using the original 64 slice EBCT scanner. Radiation exposure is about 0.7 mSv and Dr. Blanchet refers to it as a mammogram of the heart partly because of equivalent radiation exposure. If a CXR is 0.1 mSv its only 7 times more.

      The newer mechanical scanners previously used more radiation say 3 mSv (30 times a CXR) but they have improved with less radiation and better quality. Motion artifact has been the issue with these newer scanners and it has been overcome using the 256 slice technology.

    • @remigio_garcia:disqus, you should definitely get a repeat test and see if your plaque is stable. Even though your risk is high (some like you have scores in the thousands), if your calcium score remains stable that is favorable and would suggest that whatever you have been doing since 2012 has been helping.

    Dr. Gerber and Dr. Patel

    What would you recommend if a patient had a CAC score >30 on a LCHF diet?

  • PJkrt

    Is it true that one’s CT calcium score is not a measurement of arterial blockage, stenosis and/or occlusion? If so, maybe someone can add a layperson clarification of exactly what is being measured by the CT imaging.

    My own impression is that the ‘score’ is better understood as the total coronary arterial area that is affected by the calcification (versus being a measurement of narrowing and/or bulges into the artery).

    • HI @PJkrt. You’re spot on with your interpretation of calcium scoring. Calcium ‘area’ volume and density are all that can be measured and it’s associated with plaque burden, not necessarily blockage. However, its presence or not has been used to stratify CV risk (events) in literally thousands of people and the results are reproducible.

      Plaque or blood vessel inflammation develops as a response to blood vessel ‘injury’. All the mechanisms are still not fully understand but plaque starts as soft and later hard (calcium laden). Acute events occur mostly from plaque rupture and thrombus formation. The greater the plaque burden (as measured via CAC scoring) the greater the risk. Risk has little to do with the degree of stenosis.

      Rocky mentioned a small study showing that 20% of people with a ZERO calcium score actually had soft plaque. True, but the small study did not have enough power to predict risk based on these findings. It only observed that soft plaque was present.

      Bottom line, a calcium score of ZERO still means that your risk remains <1% regardless. I hope that helps.

      • PJkrt

        Thanks, Dr. Gerber.

        Following up with another question(s). You used the word ‘density.’ Does that mean the imaging is measuring both the the calcification on surface of the artery wall and the calcification behind the artery wall?

        Also, my understanding is that the ‘score’ is the total calcification of all the coronary arteries. So, if someone has calcification of ’99’ across 3 arteries, then that person may have one artery that is a ’79’ and the other two each at ’10.’ Correct understanding?

        • kanor74

 score of 67 showed 65 of it being one artery and the remaining 2 in another.

          • Nice explanation @kanor74:disqus , the areas are added together. Density describes areas on on CT with bright signals that identify a greater density of calcium.

          • PJkrt

            Let me ask another way…does the ‘score’ represent only the surface of the arterial wall calcification? Or does the CT imaging also measure calcification behind the surface of artery wall (behind the layer of endothelial cells)?

          • Ok. The test cannot identify the depth (lumen, endothelium, itima, etc…) of the calcium.

          • PJkrt

            Thanks. Well, my guess on that one was wrong. I thought it measured the compete artery calcification.

            Or is the reality that there is usually no calcification behind the endothelial cells? Instead, behind those cells are only the foam cells, excess lipids and etc. ready to rupture if surface calcification cap is too thin?

          • Might need a pathologist or cardiac surgeon to answer your question as to where the the hard plaque 1st forms.

  • Rakesh Patel, MD


    That’s amazing that you reversed your calcium score. But a correction to your blog: a zero calcium score does not mean “no evidence of plaque”. It just means no presence of calcified plaque, a very important distinction.

    Several studies in the literature demonstrate that very high risk CVD patients (those that fail myocardial perfusion testing) can often have a calcium score of zero, despite having obstructive coronary disease at time of anigogram. It was 20% percent of the peeps in this one study!

    I think if you are going to do the calcium scoring, a CT coronary angiogram is a much better assessment. I am goona assume the carotids are clean as well 😉

    cheers, rocky

    • Hi Rocky, Thanks for having a look. The chart I used is a standard oversimplified version from this source: There are other versions that provide more detail.

      I am familiar with the paper you quoted above and indeed soft plaque lesions will not be detected. I agree it’s not a perfect test but still many more will benefit from testing than not. A ZERO score still means that your risk for and event is <1% based on different sources.

      I see you are arguing for CT angiogram because it will detect all obstructions arising from either soft or hard plaque. Ok, but this has to be weighted against the invasiveness (IV contrast, more radiation) and expense vs. calcium scoring. I'm not sure asymptomatic people would want such a test.

      BTW, this was my 1st calcium score so I have no data showing regression, only that it is ZERO. The bio-markers have improved.

    • @rakeshpatelmd:disqus, I wanted to include some more sources for the table I used: Adapted from Rumberger JA et al. Mayo Clinic Proceedings March 1999: 74:243-252.

    I believe weight is a consequence and a risk factor. We can blame people for there weight while in fact it is one of the consequence. Takes years to turn this around. Same thing I believe there are many unhealty skinny people eating absolute crap. As lucky they can be… they don’t gain weight. Does this mean they should continue? I think everybody deserve a minimum respect, including overweight people.

      • charles grashow

        My question is what would you advise a patient to do if it did?

        • LLVLCBlog

          Mine is 0 eating 80% fat.

          • charles grashow

            How’s your weight BTW?

          • LLVLCBlog

            I’ve not hidden that I’ve gained weight. Reveal my numbers often on social media and my blog. Thanks for your concern.

          • Charles please behave yourself.

          • Charles is presumably a slim Jim, however calcified he managed to get himself 🙂

      Dr. Bill Davis (Wheat Belly) is a cardiologist who also uses the CT scan as part of his practice. He told me that if one is following all his protocols, one can hope to stop the progression of plaque growth or even reverse it to a degree. Following Wheat Belly or another LCHF way of eating, taking good fish oil supplements (EPA + DHA intake of 3600 mg per day ), optimizing vitamin D3, correcting bowel flora, normalizing thyroid function, and getting some exercise are all in the plan. I am a little over 3 years LCHF, 64 y/o, and got a low minimal score. My hope is to stop it or reverse it…..

      • charles grashow

        What was your score and where were the plaque(s) located?

        • kanor74

          67 almost all of which is in the left main coronary artery.

          • charles grashow

            Mine is 48 – 47 in the LAD (the widowmaker). I’ve drastically slowed the rate of progression – it’s gone from 30 in 12/07 to 48 in 2/14. My next goal is reversal which I believe is possible.

          • kanor74

            Very good! Dr. Davis told me that for folks who eat a standard diet of low fat, high carb…they can expect an increase in plaque upwards of 30% per year. So, following his protocols and eating LCHF, or in my case, Wheat Belly, I hope to stop this dead in its tracks.

          • charles grashow

            EXCEPT – I’m NOT eating Wheat Belly or LCHF. He also published a paper prior to Wheat Belly

            Effect of a Combined Therapeutic Approach of Intensive Lipid Management, Omega-3 Fatty Acid Supplementation, and Increased Serum 25 (OH) Vitamin D on Coronary Calcium Scores in Asymptomatic Adults


            The impact of intensive lipid management, omega-3 fatty acid, and vitamin D3 supplementation on atherosclerotic plaque was assessed through serial computed tomography coronary calcium scoring (CCS). Low-density lipoprotein cholesterol reduction with statin therapy has not been shown to reduce or slow progression of serial CCS in several recent studies, casting doubt on the usefulness of this approach for tracking atherosclerotic progression. In an open-label study, 45 male and female subjects with CCS of > or = 50 without symptoms of heart disease were treated with statin therapy, niacin, and omega-3 fatty acid supplementation to achieve low-density lipoprotein cholesterol and triglycerides or = 60 mg/dL; and vitamin D3 supplementation to achieve serum levels of > or = 50 ng/mL 25(OH) vitamin D, in addition to diet advice. Lipid profiles of subjects were significantly changed as follows: total cholesterol -24%, low-density lipoprotein -41%; triglycerides -42%, high-density lipoprotein +19%, and mean serum 25(OH) vitamin D levels +83%. After a mean of 18 months, 20 subjects experienced decrease in CCS with mean change of -14.5% (range 0% to -64%); 22 subjects experienced no change or slow annual rate of CCS increase of +12% (range 1%-29%). Only 3 subjects experienced annual CCS progression exceeding 29% (44%-71%). Despite wide variation in response, substantial reduction of CCS was achieved in 44% of subjects and slowed plaque growth in 49% of the subjects applying a broad treatment program.

            Notice the use of statins.

          • kanor74

            Dr. D is adamantly opposed to statin use. I’d recommend his newest book, Wheat Belly Total Health which is up-to-date on the latest research and science. I highly recommend the WB way of eating…. visit his website/blog or the official Wheat Belly Facebook page. Tons of info and happy, healthy folks who follow him.

          • charles grashow

            The paper referenced above was PUBLISHED by Dr Davis based on patient records. If he still recommends HDL>60, TG<60 and LDL<60 for reversal, please explain how LDL<60 is possible on LCHF.

          • Easy. Suppress Insulin, turn off lipogenesis, turn up lipolysis and BOOM LDL is reduced along with TG: eat your carbs and the opposite is true!

          • Davis luckily saw the error of his earlier approach Charles – he’s one of the few who has the big picture now. LDL is only a bit-player in the atherosclerosis game – respect thine Insulin and the LDL will look after itself. As nature intended it to – soon everyone will realize that evolution did not create Lipoproteins to kill us off quickly…

          • @charlesgrashow:disqus, different strokes for different folks.

          • Hey Charles – a good stint on ultra-high-fat with some intermittent fasting & sun / K2 / Mg etc. should get your score sorted – best of luck with it !

          • charles grashow

            Let’s see – I practice IF, eat food sources of + supplemental K2, I take supplemental D3 and get sunshine when I can.

            However, when I tried a VLCHF diet it sent my LDL-P soaring so that’s not a viable option

      • @kanor74:disqus best of luck with slowing your progression

        Can I enquire about this? I just received a calcium score of 533 (Agatston test) out of the blue, which surprises me greatly as I’ve been low-carb for years, supplement with fish oil (plus many others), train regularly (one glance at me would tell you I’m an athlete), had a pre-shoulder surgery pulse of 56 bpm several months ago, only to find that I’m a high risk candidate for CVD. How can this be?! All insights gratefully received.
