Lessons learned from the 2012 Low-carb Cruise

I just returned from Jimmy Moore's Low-carb Cruise, a 7-day excursion to Jamaica, Grand Cayman Island, and Cozumel aboard the Carnival Magic. During our 7 wonderful days, a number of authors and experts spoke, each offering their unique perspective on the low-carb world. The focus was the science, experience, and practical application of low-carbohydrate diets.

The event kicked off with a roast by Tom Naughton of Fat Head fame, who entertained with his insightful low-carb humor and predictions of my demise at the hands of Monsanto!

Among the most important lessons provided:

Dr. Andreas Eenfeldt of the Diet Doctor blog discussed how Sweden is leading the world as the nation with the most vigorous low-carbohydrate following, witnessing incredible weight loss and reversal of carbohydrate-related diseases way ahead of the U.S. experience. I spent several hours with Dr. Eenfeldt who, besides being an engaging speaker, is a new father and an all-around gentleman. At 6 ft, 7 inches, he also towered high above all of us.

Dr. Eric Westman of Duke University and author of The New Atkins for a New You, debunked low-carbohydrate myths, such as "low-carb diets are high-protein diets that make your kidneys explode."

Dr. John Briffa, creator of the popular blog, Dr. John Briffa: A Good Look at Good Health, and author of the wonderfully straightforward primer to low-carbohydrate eating, Escape the Diet Trap, stressed the importance of never allowing hunger to rule behavior. Dr. Briffa's serious writing tone conceals an incredible charm and wit that took me by surprise, having spent several thoroughly engaging hours over breakfast, lunch, and dinner with him over the week.

Fred Hahn, exercise expert, founder of Serious Strength and author of Slow Burn Fitness Revolution and Strong Kids, Healthy Kids, debunked a number of trendy exercise methods, boiling many of the purported benefits of exercise down to that of increased strength.

Dr. Chris Masterjohn of The Daily Lipid and supporter of the Weston A. Price Foundation program, provided a comprehensive overview of the data that fails to link saturated fat with heart disease. He also helped me understand the analytical techniques used in studies of advanced glycation end-products.

Denise Minger, brilliant young usurper of China Study dogma and blogger at Raw Foods SOS, proved an engaging speaker and a truly real person (since some critics of her analyses have actually questioned whether there was even such a person!). She also proved every bit as likable as she seems in her captivating blog discussions.

Dr. Jeff Volek, prolific researcher from University of Connecticut, author of over 200 studies validating low-carbohydrate diet effects, and author of the recently released book with Dr. Stephen Phinney, The Art and Science of Low Carbohydrate Living, debunked myths behind carbohydrate dependence and "loading" by athletes. He also talked about how assessing blood ketones may be the gold standard method to ensure low-grade ketosis on a long-term low-carb effort.

Over a bottle of wine, Jimmy Moore and I reminisced over how his modest start with no experience in blogging or media has now ballooned to an audience of over 100,000 readers/viewers.

All in all, Jimmy's Low-carb Cruise experience was worth every minute, with many wonderful lessons and memories!

    It is unfortunate that Dr Jack Kruse had to miss the cruise due to a twitter incident, but he published his intended keynote in his blog (http://jackkruse.com/ct-12-getting-back-on-board-with-my-message/). It would be extremely interesting to see Dr Kruse's program adopted by the broad low-carb community and especially in the TYP program.
    Dr Davis, would you recommend Dr Kruse's Leptin Rx and cold adaptation program to your patients? Was it in any way discussed on the cruise in the absence of Dr Kruse?

    Did you give Jimmy Moore any tips on his inability to stop gaining weight no matter how low carb he goes? It is just frightening to think that this can happen to even the most staunch and informed low carber.

    Hi Doc,

    Just heard the tail end of a story on the BBC this morning where a researcher from Oxford Univ. was recommending that everyone in the U.K. over the age of 50 be put on a statin as a prophylactic measure - arguing that based on all relevant research, the rewards dramatically outweighed the risks.  Any thoughts?

    This recipe is a filling and nutricious breakfast and you would never know you are eating low carb.

    Pam's Veggie Skillet Breakfast for Two

    1 Bunch of Asperagarus cut into 1-2 inch pieces
    1 Large red, green or yellow pepper or 3-4 small peppers diced into 1 inch pieces
    1 bunch green onions thinly sliced
    2 cloves garlic
    3 small partially cooked and diced red potatoes (or leave out if you have a very restricted carb intake or add more if you can tolerate more carbs)
    1 TBL apple cider vinegar
    3-6 eggs
    1 TBL Grape Seed Oil
    1TBL Olive Oil
    Sea Salt and Pepper

    Saute all the vegetales in a 12 inch skillet for three to five minutes with the Grape Seed Oil.  Add sea salt and pepper.  Do not over cook the veggies as they will continue to steam witth the eggs.  Add 3 to 6 eggs to the top of the vegetable bed being carefull not to break the yolk.  The trick is to gently lay the egg on top of the vegetables.  Cover the pan and let the veggies and eggs steam together until the eggs are done to your liking.  This is usually about three to five minutes for a softer egg that mixes well into the vegetable bed.  

    Serve on plates and add more salt and pepper.  Sprinkle with the apple cider vinegar and olive oil.

    Sounds yummy, though I'd replace the grapeseed oil with coconut oil.  

    A cup of grapeseed oil has 218 mg Omega-3 fatty acids and 151708 mg Omega-6, so is a pretty bad oil to use if you value your heart health.  Most of your veggie oils are this way, WAY too much omega 6 for heart health.

    I'd insist on pastured eggs (for nutrition) and freshly ground black pepper (for taste).  

    Also, this sort of thing, you don't need a recipe, this much of that veggie, this much of the other.  Basically, just whatever you have leftover in your fridge is good.  I'd need an allium of some sort (onion, shallot, scallion), but otherwise... chop and throw into a skillet whatever you've got hanging about or leftover.

    The big trick with fresh produce is using it up before it goes bad, and this is a great recipe to use stuff up with.

    I don't know enough modern biochemistry to follow the logic of the letpin reset and haven't researched the cold stuff enough to have formed an opinion yet.

    But about HIM - Google for his TED talk, where he claims to have gained 20 lbs on purpose, gone for plastic surgery to remove it, and injected himself with MRSA prior to the surgery, but it was all OK cause he soaked in a tub of ice water for hours afterwards.  

    There may be something to his ideas, but... his behavior at that talk did not elicit respect for his ideas.

    On the other hand:

    Low levels of HDL cholesterol lead to an increased death rate
    This study was published in the Journal of Lipid Research 2012 Feb;53(2):266-72

    Study title and author:
    Fifty-three year follow-up of coronary heart disease versus HDL2 and other lipoproteins in Gofman's Livermore Cohort.
    Williams PT.
    Lawrence Berkeley Laboratory, Berkeley, CA 94720, USA. ptwilliams@lbl.gov

    This study can be accessed at: http://www.ncbi.nlm.nih.gov/pubmed/22128321

    This study assessed the relationship of high density lipoprotein (HDL) cholesterol levels with total death rates and heart disease death rates. The study lasted for 53 years and included 1,905 men.

    HDL cholesterol is made of HDL 2 and HDL 3. HDL 2 is larger than HDL 3.

    After analysing 53 years of data the study found:
    (a) Those with the lowest HDL 2 cholesterol had a 22% increase in total death rates.
    (b) Those with the lowest HDL 2 cholesterol had a 63% increase in total heart disease death rates.
    (c) Those with the lowest HDL 2 cholesterol had a 117% increase in premature heart disease death rates.
    (d) Those with the lowest HDL 3 cholesterol had a 28% increase in total heart disease death rates.
    (e) Those with the lowest HDL 3 cholesterol had a 71% increase in premature heart disease death rates.

    The results of the study show that low levels of HDL cholesterol, especially HDL 2 cholesterol, are associated with higher total death rates and higher death rates from heart disease.

    The best dietary way to raise HDL cholesterol levels is to eat a diet high in saturated fat. See here.

    My focus is strictly on his ideas and how they change lives of other people when they follow his example and advice. While some people may see his behavior negatively, I respect him for taking time to reply to every single comment to his blog posts, of which he receives many hundred per post.
    I don't have a background to reason about Dr Kruse's conclusions and recommendations, but given that they are mostly consistent with the recommendations of other unorthodox doctors such as Dr Davis and Dr Eades who I trust, and go further extending those recommendations, and given that I have been following these recommendations with good consistent results, I don't need to worry about Dr Kruses's behavior when he has to deal with detractors.

  • jpatti

    6/15/2012 1:59:06 AM |

    I don't care about his detractors particularly either; I'm not a member of the Paleo community and haven't been a member of the low-carb community for some time, so have no horse in this race.

    However, his behavior in that video is pretty irrational; I don't need a detractor to tell me this; my own judgment is that messing with MRSA is just flatout STUPID.

    Dr. Davis and both of the Dr. Eades differ from Dr. Kruse in that they haven't behaved like stark raving lunatics.  I don't agree with everything they say, but respect them and have learned a lot from them, and from other sources as well.

    I've read Dr. Kruse's ideas, and as I said, I've not researched them.  They may well be valid as I haven't spent the time on PubMed to figure it out.  Similarly, I haven't researched the ideas of the folks who hang out at the Philly Amtrak station talking to invisible people.

    I can't spend my life researching, as I have to eat, sleep, exercise, talk to my husband, pet my cats, work in my garden, go to the Farmer's Market, etc.  So there must be some method of determining what to look into in depth and what to ignore; watching Dr. Kruse deliver his TED talk limited my interest in further researching his ideas.

    If his ideas ARE valid, his behavior is not earning them a hearing from me.

Low thyroid: What to do?

Low thyroid: What to do?

I've gotten a number of requests for solutions on how to solve the low thyroid issue if either 1) your doctor refuses to discuss the issue or denies it is present, or 2) there are government mandates against thyroid correction unless certain (outdated) targets are met.

Oh, boy.

While I'm not encouraging anyone to break the laws or regulations of their country (and it's impossible to generalize, with readers of this blog originating from over 30 countries), here are some simple steps to consider that might help you in your quest to correct hypothyroidism:

--Measure your body temperature--First thing in the morning either while lying in bed or go to the bathroom and measure your oral temp. Record it and, if it is consistently lower than 97.0 degrees (Fahrenheit), show it to your doctor. This may help persuade him/her.(You can still be hypothyroid with higher temperatures, but if low temperatures are present, it is simply more persuasive evidence in favor of treatment).

--Supplement with iodine 150 mcg per day to be sure you are not iodine deficient. This is becoming more common in the U.S. as people avoid iodized salt. It is quite common outside the U.S. An easy, inexpensive preparation is kelp tablets.

--Show your doctor a recent crucial study: The HUNT Study that suggests that cardiovascular mortality begins to increase at a TSH of only 1.5 or greater, not the 5.5 mIU usually used by laboratories and doctors.

--Ask people around you whether they are aware of a health practitioner who might be willing to work with you, or at least have an open mind (sadly, an uncommon commodity).

Also, see thyroid advocate and prolific author, Mary Shomon's advice on how to find a doctor willing to work with you. Yes, they are out there, but you may have to ask a lot of friends and acquaintances, or meet and fire a lot of docs. It shouldn't be this way, but it is. It will change through public pressure and education, but not by next week.

Another helpful discussion from Mary Shomon: The TSH Normal Range: Why is there still controversy? You will read that even the endocrinologists (a peculiarly contentious group) seethingly debate what constitutes normal vs. low thyroid function.

Also, you might remind a resistant health practitioner that guidelines are guidelines--they are not laws that restrain anyone. They are simply meant to represent broad population guidelines that do not take your personal health situation into consideration.

    I'd also like to add that if one can't get good thyroid care inside an HMO network or "universal" healthcare system, it can be money well spent to go "outside" the system  for private care.  Granted, paying for non-reimbursable care isn't cheap and one has to do a lot of investigating to make sure one isn't paying for more of the same inadequate care (or worse care).  But I think too many people who can afford to pay for private care suffer needlessly by doggedly sticking to inadequate care because alternatives cause a financial dent.  But in the long run, if one can find good care even though there is added expense, it can save a tremendous amount of suffering, as well as saving money.

    When I was seeing a thyroid doc out of my HMO network, I was still able to get my lab work done by the HMO approved lab  and covered by my HMO insurance (the lab faxed the results to the out-of state doc without question), though the results did go into the computerized file at my HMO network, so was visible to any HMO doc.  And my HMO insurance Rx plan covered the conventional meds prescribed by the out-of-network doc without question (but not the compounded Rx).  Yes, it cost me a few hundred dollars a year to see the doc once year, a few telephone consults, and the non-covered compounded Rx, but it well worth it.  I was finally feeling and functioning better.

    And when I went back to my HMO eventually (mostly because of travel scheduling difficulties in seeing the out-of-state doc), I was in a better position to make a case for similar care with the HMO endo (I told him flat out I'd had trouble getting good thyroid care from primary care physicians in the HMO and so went "private" for a couple years, but wanted to find someone local in the HMO for convenience) .  He doesn't do compounded Rx, and typically prescribes only Synthroid, but he accepted that I prefered T3 with the T4 (and he "accepted" the "odd" way I adjust my T4 dose with different amounts of 50 mcg Levoxyl on different days to get an overall weekly dose that works - the 50 mcg tablet has no dyes added and he accepted that I preferred Levoxyl over Synthroid).  So for the first time with the HMO system, I feel my thyroid care is more of a team effort that includes my input, instead of being at the mercy of whatever is dished out to me.  And if the situation changes, I will promptly go outside the HMO again.

    I would also suggest using the Armour site to look for prescriber's.  Their site has a little 'doctor finder' feature.

    It doesn't mean they'll necessarily treat you, but they tend to be more open-minded that doctors who prescribe Synthroid only.

    Most doctors won't use body temperature as a guide, by the way. And most won't treat Hashimoto's unless your TSH is >5. I know it's wrong, but that's how it is.

    Supplementing iodine may be helpful, unless you do have Hashimoto's, then it could make it worse (so you know). But you won't know you have Hashimoto's until you get your thyroid antibodies tested.

    A couple of other suggestions:

    Ask your doctor for Free T3/T4 AND thyroid antibodies. If your TSH >3 and your anitbodies are high, it really improves your odds of getting treatment. Many doctors ignore antibodies, but some do pay attention to them.

    If your TSH or antibodies are high at all, ask your doctor for a thyroid ultrasound. If the ultrasound is abnormal at all, it improves your odds of getting treatment too.

    Just going to a doctor with a TSH of 1.5-2.0 and normal T3/T4, it'd probably be close to impossible to get treatment. It really helps if you have the antibodies or ultrasound or something else to show the doctor.

    No person should break the law.

    However, there might be people within the arctic circle who don't have easy access to a physician who is willing to prescribe natural thyroid, including armour thyroid.

    What to do in a situation like that?

    One solution:  Find a site on the internet that provides for ordering and shipping thyroid, including Armour Thyroid, without a prescription.  There is at least one site that can be found via google that will do this.

    Warning:  There are significant dangers in supplementing thyroid without being under a doctors care.

    Regarding the thyroid issues Dr. Davis has been commenting on lately, and wondering why it seems so prevalent, have you considered the possibility that diet is playing a role.

    And when I say diet, it's probably not in the way you think --

    Carbohydrate restriction can lower thyroid hormone output, especially conversion of T4 to T3. Those who practice caloric restriction tend to have lower levels of T3 too.

    If Dr. Davis is seeing somewhat low, but still in 'normal' range T3/T4, with perhaps sluggish T3 levels, in patients AFTER they change to a no wheat, low carb diet, perhaps that is the reason why? Or perhaps that's why Dr. Davis' own thyroid had somewhat sluggish numbers?

    But if people all have high thyroid antibodies too, or all have crummy thyroid levels while eating tons of carbs, that wouldn't be a reason then.

    Just throwing that out there to think about.

    for those who are willing to do the research and check their tsh levels then ordering online is an option. start with a low dose 15 to 30 grains and then ck your tsh. Increase dose to normnal tsh levels.  There are multiple sites for armour and synthoid that do not require a prescription. When you take this road to self medication you must realize you are toally responsible for your actions and well being. Be sure you know what you are doing

    Lately I've been giving a lot of thought to the LC packaged foods that many people turn to when they first embark on a LC diet, such as low carb breads, crackers, etc.  For me, it was LC pita bread a few years ago, before I essentially went grain-free.  These products, in addition to usually having a lot of soy in them, also have added wheat gluten, to reduce the starch and boost the protein content.  Low carb they are, and generally will help with the BG control and overall weight reduction or maintenance.

    Both gluten-containing and soy foods are relatively new foods to the human diet (only consumed since the age of agriculture) and modern industrial processing bypasses many of the steps that earlier humans took to render them safer to consume.  Soy can be a powerful thyroid inhibitor (goitrogen)  and gluten can trigger an auto-immune response in susceptible people (genetic predisposition to gluten sensitivity is much more common than previously thought, though how widespread is subject to debate).  There does seem to be a strong connection to autoimmune thyroid conditions and issues with gluten.

    So people who eat a lot of soy and gluten-enhanced LC foods might be literally be shooting themselves in the thyroid, especially those who overconsume  consume them (dieters don't ever become overzealous, do they?  Smile), instead of foods that are naturally low carb and/or have a longer history in the human diet.

    I think ordering prescription medication over the internet from a less than reputable pharmacy, without a prescription, is a real bad idea. And if they don't require a prescription, that pretty much automatically makes them less than reputable.

    And don't assume thyroid medications are completely benign. They can have side effects too.
    And especially in patients with heart disease. You have to be titrated slowly and need to be under a doctor's care.

    DIY Armour/NTH treatments can be troublesome. If you are suffering from adrenal fatigue, starting immediately on thyroid replacement can cause heart palpitations and other symptoms of physical and mental anxiety. If you have low cortisol and DHEA (they invariably go together), you will probably need to take a low-dose steroid and/or DHEA replacement for a month before beginning thyroid. It is best to get these things tested first, even if you have to do it on your own. I think the Stop The Thyroid Madness author has put together some lab test packages for people to get the right things tested. And when you're taking the replacement steroids and hormones, you need to keep monitoring your levels every month at first, then every three-four months once you stabilise.

    Google for the "Top Thyroid Docs" list by Mary Shomon for sympathetic doctor suggestions/review.

    I forgot to add, the thyroid books by Dr Broda Barnes are good reading, easy to understand if you're a layman too. He had one on incidence of heart disease in patients with corrected thyroid function which is very interesting. I don't recall he mentioned wheat, but he certainly believed that we should eat good old saturated fats like butter, lard, coconut, etc, to support good health and thyroid.

    Anecdotally along with the iodine I've heard a brazil nut per day suggested for the selenium. Where I live is not selenium deficient, thanks to the end of the Ice Age glaciation: this is reputed to be one reason for the longevity here. Next time I catch a doctor I'll ask if there's much thyroid disease here (they will diagnose and treat here, my TSH was 0.99 so something is working!)

    That iodine dose may still be too low. Remember the RDA was set at a level just to prevent goiter, not for optimal health. Check out www.breastcancerchoices.org.
    Healthy Japanese get 12.5mg (12500 mcg) of iodine per day. Probably we are all low in iodine and bromine competes for binding sites. Bromine is ubiquitous in our chemically laden environment and is used as a dough conditioner by commercial bakeries---they used to use iodine. The thyroid gets the bulk of our low iodine but it turns out that iodine is also concentrated in our gonads, adrenals and especially the breasts. Our epidemic of breast cancer and fibrocystic disease may be due to iodine deficiency.

    Dr. Davis,

    I realize that you aren't in the business of diagnosing ailments or conditions via the internet, but I've recently experienced some hypothyroidism symptoms (low body temp. average of 96.7, fatigue, weight gain, hair loss, etc..) that my Doctor insists are unrelated to the disease.  In addition, he has also just put me on a combination of Crestor and Trilipix for an abnormally high triglyceride reading, despite this reading being a one-time fluke.

    My labs are as follows:
    TSH:       2.761
    Thyroxine (T4): 6.4

    He was not interested in doing any more thyroid testing beyond these two.

    Lipids:
    Total Cholesterol: 165
    Triglycerides:     415
    HDL:               22
    LDL:               N/A

    After a week on the Crestor (10mg) / Trilipx (135mg) combo, I was stricken with muscle aches and pains, tinnitus, popping ears, dizziness and a foggy out-of-it feeling.  After two weeks and finding your site, I discontinued the use of the two cholesterol medications against the Doctor's advice.  I've since starting taking an Omega 3-6-9 supplement three times daily along with my daily multi-vitamin.  I also take diazide/HCTZ for slightly elevated BP (130/96) and have recently begun following a strick low-carb diet and exercise routine.

    Again, I don't expect a diagnosis from you, but would appreciate if if you could voice your thoughts on the viability of me continuing to find a doctor willing to be more open minded to thyroid issues as well as pursuing more natural remedies to lipid issues.  

    Thanks for providing such a valuable resource for those of us who are getting fed up with the flawed standard of care that is currently being forced on so many people.



    My labs show the following.

    I agree on the iodine dose question.

    The difficulty comes in trying to generate conversation through the blog for people who may or may not, for instance, have underlying Hashimoto's thyroiditis or thyroid nodules, in which case taking higher doses of iodine can trigger extreme excesses of thyroid hormone.

    I had been on Sythyroid for a few years but no one had ever mentioned or tested for Hashimoto's. Still feeling horrible, I found a holistic MD, and was diagnosed with Hashimoto's and started on Armour.
    Do I still have Hashimoto's or is it quiet now that I am taking a different hormone?
    The holistic said it would "kill" my thyroid and move on to another area, like adrenals.
    I did have a positive ANA for many years and tested for Lupus, RA, etc. many times. Then routine testing showed my ANA had returned to normal values.  
    Any ideas because my current endo. sure isn't forthcoming with any and doesn't/hasn't tested for antibodies.  He feels I am just hypothyroid.
    I appreciate all your information!

    2/11/2009 5:20:00 AM |

    To test for Hashimoto's you need your TPO and TGAB antibodies tested. If they are above normal range, you probably have it. The definitive diagnosis is via a biopsy, but without a nodule that isn't usually done. An ultrasound is another diagnostic tool -- if your thyroid looks enlarged, nodular or all lumpy, along with antibodies, it's pretty safe to say you have Hashimoto's.

    I have never read, or heard of, Hashimoto's 'attacking' other organs after your thyroid is burnt out. That theory seems a bit out there to me.

    Antibodies can fluctuate, and with thyroid hormones usually become lower over time.  Inflammation tends to be reduces with hormones too.

    OK I caught one of our GPs yesterday, the selenium in the soil connection appears to be a non-starter. Her experience was that she found hypothyroid "quite often" predominantly in post-menopausal women and with incidence increasing with age. It's impossible to compare numbers with other areas since they actively look for the condition here and don't elsewhere. Also we have a lot of local longevity so more patients with systems wearing out purely through ageing.

    I always wonder about something I hear frequently - the issue of "soil mineral depletion".  Not that it isn't possible, but how significant is this and how widespread?  People don't generally eat "locally" produced food anymore; food supplies are distributed from all over the globe now, though agriculture is quite intense in some places, like the Central Valley of California, or cornfield in Iowa.  Wouldn't the shipping of food products all over sort of "average out" the minerals like iodine and selenium?  Or are  all the major agricultural regions of the world growing with depleted soil propped up with little more than NPK replacement?  

    I'm actually more into local, seasonal organic food than worldwide food.  LIving near the coast, presumably there is adequate iodine in the soil, but here I am, hypothyroid anyway.  Just wondering...

    Hard to tell about the soil mineral depletion thing, there are major regional variations which can show in animal diseases and require supplementation, salt licks etc. as well as human disease clusters. Deficiencies can show before "deficiency diseases"

    I trialled several different supplements but none of them made any discernible difference, probably a widely varying diet helps, plus fish, and local farmers who use high levels of organic manure and feed the soil as a whole rather than (increasingly expensive) stuff out of a bag and treat the soil as a sterile growing medium. Grass-fed rather than grain-fed meat, and game, probably helps too in picking up trace elements

    The downside of World Trade may be that while you get more trace elements from crops from different regions you are probably also getting more pesticides some of which are banned in the West

I asked him about Armour thyroid he said that he has hundreds of patients on Synthroid with no problems and I don't want to start a new prescription without my family doctor knowing about it. I'm on 75mcg of Synthroid and would really like to try Armour thyroid...might have to wait until he retires (could be soon) before I see if I can get Armour..

    Dr. Brownstein (Family physician, holistic doc in Michigan) in his book, "Iodine, Why You need it, Why You can't live without it" makes an interesting case for temporarily increased TSH (5-30mU/L higher) after correcting iodine deficiency.

    In addition to just stimulating thyroid hormone production, TSH also increases the production of the iodine transport cells (NIS). Without more NIS available, iodine couldn't enter the cells and be utilized. Therefore, increased TSH makes sense during the initial phase of iodine correction.

    As one increases their iodine consumption, they could experience this increase in TSH for as long as several months. As long as the T3 and T4 levels are normal, then the TSH elevation probably isn't a sign of hypothyroidism.

    If you haven't yet read this book, it's worth the 2 hours it took me to get through it.

Carb counting

Carb counting

In the recent Heart Scan Blog post, Can I eat quinoa, I discussed how non-wheat carbohydrate sources like quinoa, amaranth, black beans, brown rice, fruit, etc. do not exert the inflammation-provoking, appetite-increasing effects of wheat (since gliadin and gluten are not present), nor do they increase blood glucose as enthusiastically as the amylopectin A of wheat--but non-wheat grains can still increase blood sugar quite substantially.

Of course, any food that triggers blood sugar also trigger hepatic de novo lipogenesis, thereby increasing triglyceride levels and postprandial particles (e.g., chylomicron remnants), which, in turn, triggers formation of small LDL particles.

So these non-wheat carbohydrates, or what I call "intermediate carbohydrates" (for lack of a better term; low-glycemic index is falsely reassuring) still trigger all the carbohydrate phenomena of table sugar. Is it possible to obtain the fiber, B-vitamin, flavonoid benefits of these intermediate carbohydrates without triggering the undesirable carbohydrate consequences?

Yes, by using small portions. Small portions are tolerated by most people without triggering all these phenomena. Problem: Individual sensitivity varies widely. One person's perfectly safe portion size is another person's deadly dose. For instance, I've witnessed many extreme differences, such as 1-hour blood sugar after 6 oz unsweetened yogurt of 250 mg/dl in one person, 105 mg/dl in another. So checking 1-hour blood sugars is a confident means of assessing individual sensitivity to carbs.

Some people don't like the idea of checking blood sugars, however. Or, there might be times when it's inconvenient or unavailable. A useful alternative: Count carbohydrate grams. (Count "net" carbohydrate grams, of course, i.e., carbohydrates minus indigestible fiber grams to yield "net" carbs.) Most people can tolerate around 40-50 grams carbohydrates per day and deal with them effectively, provided they are spaced out throughout the day and not all at once. Only the most sensitive, e.g., diabetics, apo E2 people, those with familial hypertriglyceridemia, are intolerant to even this amount and do better with less than 30 grams per day. Then there are the genetically gifted from a carbohydrate perspective, people who can tolerate 50-60 grams, occasionally somewhat more.

People will sometimes say things like "You don't know what the hell you're talking about because I eat 200 grams carbohydrate per day and I'm normal weight and have perfect blood sugar and lipids." As in many things, the crude measures made are falsely reassuring. Glycation, for instance, from postprandial blood sugars of "only" 140 mg/dl--typical after, say, unsweetened oatmeal--still works its unhealthy magic and will lead long-term to cataracts, arthritis, and other conditions.

Humans were not meant to consume an endless supply of readily-digestible carbohydrates. Counting carbohydrates is another way to "tighten up" a carbohydrate restriction.

    Always great information!  So you are saying that for the normal healthy person, a target of 40-50 carbs a day is the max we should take in to avoid inflammation and they host of issues that go along with it?  I ask b/c if you eat enough veggies and fruit, even without sugar or wheat, it is easy to push over the 40-50 carbs.  Just wanted to make sure I understand so I can tune in my numbers.  Thank you for all of your work!

    Hyper-glycemia is able to increase the levels of matrix metallo-proteinase 9 (MMP 9), an endo-peptidase enzyme implicated in alterations of blood vessels'   walls.  It is thought to play a role in aortic aneurisms; and, since MMP 9 is made in plaque, it is also implicated in ruptures of plaque. There is a notable increase in MMP levels in individuals with  familial hyper-cholesterol and diabetics.

    Diabetics have elevated urine & blood levels of MMP 9;  but also above normal levels of  it's  inhibitor  (tissue inhibitor metallo-proteinase, or TIMP). The theory is that these conflicting markers indicate there is an ongoing paradigm, in which  vascular exterior cell matrix (ECM) remodeling is aggravated, by the influence of hyper-glycemia, and this is being opposed by a body response, which tries to keep vascular walls from getting so misshapen they lose function. (To be clear this is not necessarily a narrowing of the inside of the small blood vessels; more a case where, when measured across, it is wider. And then too this is not directly causing any worsening of systolic pressure.)

    Since nothing is simple know that both too much MMP and too much of it's inhibitor TIMP are not desirable. On one hand if there is too much TIMP (ie: low MMP) then the ECM can become more fibrous from excess collagen allowed into that vessels matrix; so normal amounts of MMP is desireable. While in another context it is suggested that the way advanced glycation end products (AGE) increases oxidative stress contributes to more MMP 9; and then the high levels of vascular adhesion molecules (VAM 1),  that are notably induced by AGEs,  get to cause more monocyte adhesion to the MMP enzyme prepped vascular endothelium.

    I wonder how folks who follow insane diets like Dr. Furhman's Eat to Live manage to keep their blood sugars down? According to his web site, they do manage to doso, and they keep their HDL up and their triglycerides down. There's something going on there but I'm not sure quite what it is. The diet avoids meat and fat, but it also avoids sugar and grains as well. They apparently eat a lot of beans.
    Anyway, anyone could get the same results or better without avoiding meat like it's the devil, but that's another story.

    The lactose content of yogurt varies a lot depending on how long it's allowed to ferment. Most people don't like sour yogurt, so most commercial yogurt producers stop the fermentation when it's still pretty sweet, even without added sweetener. The sourer the yogurt, the less milk sugar remaining. So differences in BGs after eating yogurt might stem from the level of fermentation as well as from individual differences in blood sugar control and allergies.

    Not everyone goes up to 140 after meals, even very carby ones. If you look at this chart carefully, you can see that although many people go over 160 after a carby breakfast, some start below 70 and only go up to about 90 after breakfast.

    http://www.diabetes-symposium.org/index.php?menu=view&source=topics&sourceid=16&chart=17&id=322

    Some people on diabetes lists have tested spouses, and many say they never go above 90, although with hearsay reports like this it's not always clear when they were testing. Nondiabetics can go up to 160 after a carby meal and be back to below 100 in an hour or two.

    One person who had tested diabetic and then lost about 100 pounds said that after the weight loss, he never went over 100 unless he really stuffed himself, and then I think he only went up to slightly over 100.

    @ mcfreddy: same with the 'starch based' McDougall diet. (high carb, no added fat, no animal or dairy,  just heavy on veggies, fruits, beans, lots of sweet potatoes and potatoes - and grains as tolerated).

    A fasted homeostatic blood sugar level equals around1 teaspoon of sugar out of the 1000 teaspoons of blood in your body.  When analyzing food labels & tracking your carb intake the formula to remember is the 1-5-20 rule, meaning 1 teaspoon of sugar equals 5 grams which equals 20 calories.  For optimum health an honest dietitian, nutritionist or doctor will advise keeping TOTAL carb (sugar) intake to around 10 to 12 teaspoons a day MAX, others will say 10 to 12 or 15  total ADDED sugars per day.  12 teaspoons X 5 grams per equals only 60 grams & times 20 calories per teaspoon equals just 240 calories. So yes it's not much, but considering the damage done to the body by glucose from carbs, & since ALL carbs reduce to glucose, less is better.

    Hi rhc,
    You realize I discussed above an  aortic aneurism; this is not in the brain. As for hemorrhagic stroke there is a risk  condition one can be born with,  relatively rare to be sure, called arterio-venous malfunction; while the common sub-arachnoid hemorrhage can be either looming likewise since birth or as a rupture associated with advancing age.
    Sounds like you might be alluding to an intra-cerebral hemorrhage of some artery inside the brain. These are usually ascribed to hyper-tension's affect on brain artery.

    I am assuming you are directing your comments at sedentary unfit people.  Anyone who works  physically or trains as I do (I run and do heavy weight training), could not survive and train on those sorts of amounts of carbs.  If I go below about 200g/day for any length of time my ability to train drops off markedly.

    Dr. Davis, thank you really so much. Very interesting article. I believe it is also not just a a matter of the right source of carbohydrate and carb counting but also the right food combining. But what is a person has to do a lot of intelletual work? For example,  when I have to solve a lot or complicated mathematical tasks and make serious projects involving higher mathematics I just cannot do without much carbs, much more than most of my familiy members. Otherwise, it feels like the brain gets dry. On the other hand, physical  workouts never make me really hungry. IS that ok?

What tests are MORE important than cholesterol?

What tests are MORE important than cholesterol?

In the conventional practice of early heart disease prevention, cholesterol testing takes center stage. Rarely does it go any further, aside from questions about family history and obvious sources of modifiable risk such as smoking and sedentary lifestyle.

So standard practice is to usually look at your LDL cholesterol, the value that is calculated, not measured, then--almost without fail--prescribe a statin drug. While there are indeed useful values in the standard cholesterol panel--HDL cholesterol and triglycerides--they are typically ignored or prompt no specific action.

But a genuine effort at heart disease prevention should go farther than an assessment of calculated LDL cholesterol, as there are many ways that humans develop coronary atherosclerosis. Among the tests to consider in order to craft a truly effect heart disease prevention program are:

--Lipoprotein testing--Rather than using the amount of cholesterol in the various fractions of blood as a crude surrogate for lipoproteins in the bloodstream, why not measure lipoproteins themselves? These techniques have been around for over 20 years, but are simply not part of standard practice.

Lipoprotein testing especially allows you to understand what proportion of LDL particles are the truly unhealthy small LDL particles (that are oxidation- and glycation-prone). It also identifies whether or not you have lipoprotein(a), the heritable factor that confers superior survival capacity in a wild environment ("The Perfect Carnivore"), but makes the holder of this genetic pattern the least tolerant to the modern diet dominated by grains and sugars, devoid of fat and organ meats.

--25-hydroxy vitamin D--The data documenting the health power of vitamin D restoration continue to grow, with benefits on blood sugar and insulin, blood pressure, bone density, protection from winter "blues" (seasonal affective disorder), decrease in falls and fractures, decrease in cancer, decrease in cardiovascular events. I aim to keep 25-hydroxy vitamin D at a level of 60 to 70 ng/ml. This generally requires 4000-8000 units per day in gelcap form, at least for the first 3 or so years, after which there is a decrease in need. Daily supplementation is better than weekly, monthly, or other less-frequent regimens. The D3 (cholecalciferol) form is superior to the non-human D2 (ergocalciferol) form.

--Hemoglobin A1c (HbA1c)--HbA1c represents glycated hemoglobin, i.e., hemoglobin molecules within red blood cells that are irreversibly modified by glucose, or blood sugar. It therefore provides an index of endogenous glycation of all proteins of the body: proteins in the lenses of the eyes that lead to cataracts; proteins in the cartilage of the knees and hips that lead to brittle cartilage and arthritis; proteins in kidney tissue leading to kidney dysfunction.

HbA1c provides an incredibly clear snapshot of health: It reflects the amount of glycation you have been exposed to over the past 90 or so days. We therefore aim for an ideal level: 5.0% or less, the amount of "ambient" glycation that occurs just with living life. We reject the notion that a HbA1c level of 6.0% is acceptable just because you don't "need" diabetes medication, the thinking that drives conventional medical practice.

--RBC Omega-3 Index--The average American consumes very little omega-3 fatty acids, EPA and DHA, such that a typical omega-3 RBC Index, i.e., the proportion of fatty acids in the red blood cell occupied by omega-3 fatty acids, is around 2-3%, a level associated with increased potential for sudden cardiac death (death!). Levels of 6% or greater are associated with reduced potential for sudden cardiac death; 10% or greater are associated with reduced other cardiovascular events.

Evidence therefore suggests that an RBC Omega-3 Index of 10% or greater is desirable, a level generally achieved by obtaining 3000-3600 mg EPA + DHA per day (more or less, depending on the form consumed, an issue for future discussion).

--Thyroid testing (TSH, free T3, free T4)--Even subtle degrees of thyroid dysfunction can double, triple, even quadruple cardiovascular risk. TSH values, for instance, within the previously presumed "normal" range, pose increased risk for cardiovascular death; a TSH level of 4.0 mIU, for instance, is associated with more than double the relative risk of a level of 1.0.

Sad fact: the endocrinology community, not keeping abreast of the concerning issues coming from the toxicological community regarding perchlorates, polyfluorooctanoic acid and other fluorinated hydrocarbons, polybrominated diphenyl ethers (PDBEs), and other thyroid-toxic compounds, tend to ignore these issues, while the public is increasingly exposed to the increased cardiovascular risk of even modest degrees of thyroid dysfunction. Don't commit the same crime of ignorance: Thyroid dysfunction in this age of endocrine disruption can be crucial to cardiovascular and overall health.


All in all, there are a number of common blood tests that are relevant--no, crucial--for achieving heart health. Last on the list: standard cholesterol testing.

    My husband decided to give going gluten free a try after I read your book, and shared many things with him.  He has a number of issues.  HBP and taking meds.  Asthma, knee injuries with multiple surgeries over the years, and based on his lipid panel numbers, his dr. like you said, wanted to put him on a chol. reducer.  He went gf for a month, this past month, and just this week had his blood work done.  His LDL # went up from 146 to 164, and his HDL went from 45 to 47.   His Trig at least, dropped from 190 to 122,  So he now has in hand a scrip for atorvastatin (sp.?)..  Even though my husband would be considered a slender 48 year old, he has lost 6 pounds during this month of being wheat free.  I personally began a trek of losing weight a year ago by cutting wheat and sugar, and lost over 30 pounds, going from a size 12 to a 2.  I never had any blood work done, since I didn't have any health issues.  I was really hoping for better results for my husbands numbers so that we could provide a valid testimony to those unbelievers within our family.  I don't have your book memorized, but I've scanned through the blog posts and comments and found bits and pieces about numbers and how some people experience an increase like my husband Bill did.  Could you give me a bullet point laymen's version of the reason for the increase, if it's a concern, and if not, should he get the prescription filled like the dr. ordered so that he can then do the 3 month follow up to see if the med. worked for lowering the #'s?
    OR should I just go back and do some more reading like of the above post and reread the book?

    Tests are important, and I think that there are more people today who are interested in keeping track of their cholesterol levels. This is why I think we live in such a special time. We have access to more information than ever before, and now people can learn about high cholesterol risks without having to go to the doctor. In fact, I have found a number of sites that allow people to track their cholesterol levels online. Obviously, there are some people who may go overboard with access to this information, but I do think that there are plenty of benefits to be had.

More on ASTEROID

More on ASTEROID

Since we are on the topic of the ASTEROID trial and rosuvastatin, I'd make one more point before I start to sound like I'm plugging this drug (which I definitely am not).

In an informative Roundtable Discussion (open to subscribers to the American Journal of Cardiology; sorry) amongst Dr. Steve Nissen, principal investigator behind ASTEROID; and Drs. Vincent Friedewald, Christie Ballantyne, P. Shah, and William Roberts, Dr. Nissen made some interesting comments:


Dr. Shah: In ASTEROID, was the magnitude of atheroma volume change seen across different levels of LDL-C and HDL-C?

Dr. Nissen: No. There was no plaque regression seen in the 17 persons with LDL-Cs >/= 100 mg/dl, and there was little change in persons with LDL-Cs of 70 to 100 mg/dl. Only in persons with LDLs less than or equal to 70 mg/dl was there significant regression. The study was not powered to look for an HDL-C(which increased by 14.7%)-raising effect.



Interesting. In other words, ASTEROID, in a fairly internally consistent way, suggests that the lower the LDL is reduced, the more likely plaque regression is obtained. This is consistent with the Track Your Plaque experience, in which we've advocated reducing (calculated) LDL cholesterol to 60 mg/dl for the past several years.

Unfortunately, the message that the ASTEROID Trial sponsors, AstraZeneca, as well as the roundtable discussion panel (later in the discussion) try to make is that there is something magical about Crestor, that it yields benefits superior to other statin agents or other means of reducing LDL.

I disagree with this message. In the Track Your Plaque experience, we do aim for a similar LDL target. But we also employ a number of other strategies. We have also succeeded in regressing plaque without use of any statin drugs (though, admittedly, many people do require statin drugs to obtain LDLs in this range). We also witness magnitudes of reversal that often far exceed that seen in ASTEROID.

The Rountable Discussion is unfortunately tainted, as is the ASTEROID Trial itself, with deep drug industry financial involvement of the Roundtable participants. In fact, the discussion begins with a listing of the financial disclosures of the participants, a listing that occupies a full column of a two-column page. The potential biases of the participants doesn't necessarily invalidate the arguments, but to me suggests that participants are more likely to argue in favor of the sponsor's drug, or that participants were chosen because of these biases.

Why bother to even mention the ASTEROID Trial in a venue (the Heart Scan Blog, that is) that purports to seek unvarnished, unbiased truth in coronary plaque reversal? Because useful information can sometimes be found in unlikely places. Just like the four-year old child who blurts out an unexpected pearl of wisdom, so it can happen with the gobbledy-gook that emerges from the drug industry.

Every once in a while, they are worth paying attention to.

    Dr. Davis, your readers may be interested to listen to a recent BBC Radio 4 program which takes a close look at some impressive-sounding figures obtained from statin drug trials and shows how they are in fact not in the least bit impressive (e.g. a reduction in mortality from 3 in 600 people to 2 in 600 being hyped by statin manufacturers as being an over 33% reduction! Brings to mind Disraeli's adage about damned lies and statistics.

    The take home message is that statins appear to be hugely over-subscribed - the UK is gaining on the US in this regard - and statins are of no benefit for 99% of people taking them for primary prevention of heart disease.
