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the issue or denies it is present, or 2) there are government mandates against thyroid correction unless certain (outdated) targets are met.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...

  • Trinkwasser

    2/15/2009 3:47:00 PM |

    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'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.

Family lessons

Lou was recovering from his 3rd bypass operation. This third go-round left him weaker, slower, less quick on the rebound. In fact, he was lucky to have survived.

At 71 years old, Lou went a good 15 years since his second bypass, another 10 years prior to his first bypass at age 46.

In the days immediately following Lou's bypass, I had a chance to talk to his son, who stayed at his Dad's bedside while Lou struggled through post-op recovery.

"Did your Dad tell you about why this has happened, what caused his heart disease?" I asked.

"Sort of. He just said I should get checked," Lou's son, Aaron, replied.

"Did he mention the lipoprotein(a) pattern he has?"

"No. He never mentioned anything like that. He just said to get checked."

That's how it gets played out more often than not: Mom or Dad has a heart attack, stents, or (3rd) bypass, the children are told to get checked. Getting "checked" assumes that the doctor knows what to check for.

In Lou's case, the reason why he was in the hospital getting his 3rd (and final) bypass was lipoprotein(a), along with genetically-determined small LDL particles, low HDL, a postprandial (after-eating) disorder, hypertension, and borderline diabetes, not to mention vitamin D deficiency, omega-3 fatty acid deficiency, and marginal thyroid function. (Lou, a retired city employee, had showed only marginal interest in correcting these patterns. While he accepted medications, he proved unwilling to engage in the diet and nutritional supplement strategies required to correct his patterns.)

So Lou's 3rd bypass operation provided a moment of reflection for Aaron to ask: "Could I share the fate of my Dad?" With Lou's combination of genetic patterns, there was at least a 75% likelihood that he did. Sadly, going to his doctor would likely yield little more than a cholesterol panel, a question about smoking, and a prescription for Lipitor.

Just getting "checked" would be, more than likely, a recipe for disaster for Aaron: heart disease in his 40s or 50s. That's why you need to take control over this sad state of affairs and ask--no, insist--that an effort be made to determine whether you might share your parents' fate.

Look like Jimmy Stewart


"This diet works great," Don declared. "But I think I've lost too much weight."

At 67 years old and 5 ft. 11 inches, Don began the program weighing 228 lbs (BMI 31.9). Because of high triglycerides, high blood sugar, high c-reactive protein, and excessive small LDL, I instructed Don to eliminate all wheat products from his diet, along with cornstarch and sweets. His intake of lean meats, eggs, vegetables, oils, raw nuts, etc. was unlimited.

Don now weighed 194 lbs, down 34 lbs over 6 months (BMI 27.1). Triglycerides, blood sugar, blood pressure, and well-being had improved dramatically; small LDL, however, had dropped only 30%--still room for improvement.

"My friends say I'm too skinny. They ask if I have cancer!"

I've heard this many times: Someone loses weight in a relatively short period of time and friends and family tell you you're too skinny. "It must be cancer. Nobody loses weight like that."

Unfortunately, many Americans have forgotten what normal looks like. Normal is certainly not a 190-lb, 5 ft 4 in woman, nor is it a 228 lb, 5 ft 11 inch man. But Americans have put on so much weight that the prevailing view of what constitutes "normal" weight has been revised upward. Normal is closer to what we see in old movies from the 1940s and '50s with people like Jimmy Stewart and Donna Reed. That's what we are supposed to look like.

So Don actually remains mildly overweight but is judged as "too skinny," or even cancer-ridden, by friends and family.

Ignore such comments. As you lose pounds and approach a truly desirable weight, realize that you are returning to the normal state, not the vision of "normal" now held by most Americans.

Getting vitamin D right

Vitamin D is, without a doubt, the most incredible "vitamin"/prohormone/neurosteroid I have ever encountered. Frankly, I don't know how we got anything accomplished in health pre-D.

Unfortunately, people I meet rarely take their vitamin D in a way that accomplishes full restoration of vitamin D blood levels. It really isn't that tough.

Here's a list of common tripping points with vitamin D:

"I take vitamin D: 1000 units a day."
This is probably the most common mistake I see: Taking a dose that is unlikely to yield a desirable blood level. (We use 60-70 ng/ml of 25-hydroxy vitamin D as our target.) Most men and women require 6000 units per day to achieve this level. There is substantial individual variation, however, with an occasional person needing much more, a rare person requiring as little as 1000 units.


"I bought some vitamin D on sale. They were white tablets."
Time and again, patients in my office who initially have had successful vitamin D replacement, despite being reminded that only oil-based forms should be taken, switch to tablets. While they initially showed a 25-hydroxy vitamin D blood level, for instance, of 67 ng/ml on 8000 units per day with an oil-based capsule, they switch to a tablet form and the next blood level is 25 ng/ml. In other words, tablets are very poorly or erratically absorbed.

I have had people use tablets successfully, however, by taking their vitamin D tablets with a teaspoon of oil, e.g., olive oil. Oil is necessary for full absorption.


"I'm going to Florida. I'll stop my vitamin D because I'm going to lay in the sun."
Wrong. 90% of adults over 40 years old have lost the majority of their ability to activate vitamin D in the skin. A typical response might be an increase in blood level from 25 to 35 ng/ml--a 10 ng increase with a dark brown tan.

There is an occasional person who, with sun exposure, increases blood levels substantially. This can occur in both fair-skinned and dark-skinned people, though I've never seen it happen in an African-American person. The occasional person who maintains the ability to convert vitamin D with sun exposure, or young people, should seasonally adjust their vitamin D dose, e.g., 6000 units winter, 3000 units summer, or some other regimen that maintains desirable blood levels. You can see that monitoring blood levels (we check levels every 6 months for the first 2 years) is crucial: You cannot know what your vitamin D needs are unless you assess 25-hydroxy vitamin D levels.


"I drink plenty of milk. I don't think I need to take vitamin D."
Oh, boy. This is so wrong on so many levels.

First of all, no adult should be drinking plenty of cow's milk. (A discussion for another day.) Second of all, cow's milk averages 70 units of vitamin D, often the D2 form (ergocalciferol), per 8 oz. Even if the FDA-mandated 100 units per day were present, an average adult dose of 6000 units would require 60 glasses of milk per day. Can you say "diarrhea"?

Likewise, other food sources of vitamin D, such as fish (300-400 units per serving) and egg yolks (20 units per yolk), are inadequate. This makes sense: Humans are not meant to obtain vitamin D from food, but from sun exposure over a large body surface area. And this is a phenomenon that is meant to occur only in the youthful, ensuring that nature takes its course and us older folks get old and make way for the young (i.e., unless we intervene by taking vitamin D supplements).


"My doctor said that my vitamin D blood level was fine. It was 32 ng/ml."

Let's face it: By necessity, your overworked primary care physician, who manages gout, hip arthritis, migraine headaches, stomach aches, prostate enlargement, H1N1, depression, etc., is an amateur at nearly everything, expert in nothing. Nobody can do it all and get it right. Likewise vitamin D. The uncertain primary care physician will simply follow the dictates of the laboratory form that specifies "30-100 ng/ml" as the "normal" or "reference range." Unfortunately, the laboratory often quotes population distributions of a lab measure, not an ideal or desirable level.

To illustrate the folly of population distributions of a measure, imagine you and I want to know what women weigh. We go to a local mall and weigh several thousand women. We tally up the results and find that women weigh 172 lbs +/- 25 lbs (the mean +/- 2 standard deviations). (That's true, by the way.) Is that desirable? Of course it isn't. Population average or population distribution does not necessarily mean ideal or desirable.


"My husband's doctor said he should take 4000 units per day. So I just take the same dose."
That would be fine if all adults required the same dose. However, individual needs can vary enormously. A dose that is grossly insufficient for one person may be excessive for another. Once again, vitamin D dose needs can be individualized by assessing 25-hydroxy vitamin levels in the blood.


"I don't need to take vitamin D. I already take fish oil."
I suspect this mistaken belief occurs either because people confuse fish oil with cod liver oil, which does contain some vitamin D. (Cod liver oil is not the best source of vitamin D, mostly because of the vitamin A content; also a discussion for another time), or because they've heard that eating fish provides vitamin D. However, fish oil capsules do not contain vitamin D unless it is added, in which case it should be prominently and explicitly stated on the label.


"I don't have to take vitamin D. It's summer."

For most people I know, if it's a bright, sunny July day, where are they likely to be? In an office, store, or home--NOT lying in the sun with a large body surface area exposed. Also, most people expose no more than 5-10% of surface area in public. I doubt you cut the grass in a bathing suit. Because of modern indoor lifestyles and fashion, the majority of adults need vitamin D supplementation year-round.


I advise everyone that gelcap vitamin D is preferable. Some, though not all, liquid drop forms have also worked. Take a dose that yields desirable blood levels. And blood levels of 25-hydroxy vitamin D are ideally checked every 6 months: in summer and in winter to provide feedback on how much sun activation of D you obtain.

If your doctor is unwilling or unable to perform vitamin D testing, fingerstick vitamin D test kits can be obtained from Track Your Plaque.

Jimmy Moore's thyroid adventure

My friend, Jimmy Moore of Living La Vida Low Carb, describes his thyroid experience here.

As Jimmy points out, he was looking for a way to jump-start a 50-lb weight loss. In my experience, low thyroid hormone levels ("hypothyroidism") are an exceptionally common cause for weight gain. Correcting even marginal hypothyroidism can facilitate weight loss, often resulting in 10 or more pounds of weight loss within the first month.

Unfortunately, Jimmy's thyroid hormone panel proved normal: TSH 1.3, thyroid hormones free T3 and free T4 in the mid- to upper-half of the reference range.

I say "unfortunately" because it is really an easy, inexpensive, and benign solution for losing weight. (I don't, of course, wish that Jimmy or anyone else develops a thyroid condition. But it really can provide gratifying weight loss results when thyroid function is low.) Jimmy might consider taking his oral temperature first thing in the morning as another means of assessing the adequacy of thyroid function.

Perhaps you will be luckier than Jimmy and have thyroid dysfunction that can be corrected and jump-start your weight loss program. Fingerstick thyroid test kits like the one Jimmy used are available here from Track Your Plaque.

What's that in your mouth?




Fat = triglycerides

In other words, eat fat, whether it's saturated, hydrogenated, polyunsaturated, or monounsaturated, and blood levels of triglycerides will go up over the next 6 hours. This remains true if there are carbohydrates in the meal, or if there are NO carbohydrates in the meal. It also remains true if you chronically consume fats.

While fats are the primary determinant of postprandial (after-eating) triglycerides, carbohydrates are the primary determinant of fasting triglycerides.

So, if your triglycerides are high on a fasting cholesterol (lipid) panel, it's most likely because you overconsume carbohydrates.

De Novo Lipo-what?

Humans have limited capacity to store carbohydrates. Beyond the glucose and glycogen in our blood and tissues, we have relatively little carbohydrate to draw from in time of energy need. That's why long-distance runners and triathletes have to carry sugar sources to keep blood sugar from plummeting.

Fat, of course, is different. We have virtually unlimited capacity to store energy as fat.

Because we have limited carbohydrate storage capacity, what can the body do with the excessive quantities of carbohydrates that Americans ingest? What becomes of a bagel for breakfast, wheat crackers for snacks, a whole wheat sandwich for lunch, pretzels, and whole wheat pasta that many people eat every day, not to mention the chips, soft drinks, and juices?

Excess carbohydrates are diverted to an interesting metabolic pathway called de novo lipogenesis (DNL). This refers to the liver's ability to make triglycerides from excessive carbohydrates in the diet. Triglycerides are packaged for release into the blood as VLDL. VLDL, in turn, interacts with other lipoproteins, creating small LDL particles, reduced HDL and smaller, less protective HDL. High VLDL will be measured on a standard cholesterol panel as higher triglycerides.

A University of California (Berkeley, San Francisco) group has done much of the work describing DNL.

A diet weighed towards carbohydrates, especially if 50% or greater calories are carbohydrate, is sufficient to provoke plenty of DNL, even in slender people. DNL is a big part of the reason why low-fat (and, thereby, high-carbohydrate) diets result in higher triglycerides. DNL really gets turned on many-fold if the carbohydrates are "simple," rather than "complex."

Overweight people, however, can demonstrate five-fold greater DNL even with lesser quantities of carbohydrate intake (e.g., 40% fat, 46% carbohydrate, 14% protein):





From Schwarz et al 2003. Mean (± SEM) fractional de novo lipogenesis in lean normoinsulinemic (NI), obese NI, and obese hyperinsulinemic (HI) subjects after 5 d of consuming a high-fat, low-carbohydrate diet and in different lean NI and obese HI subjects after 5 d of consuming a low-fat, high-carbohydrate diet. Values with different superscript letters are significantly different.


Excessive carbohydrates, a la standard low-fat diets, are good for nobody. The concept of de novo lipogenesis fills in a theoretical hole that now explains why people who eat carbohydrates have higher triglycerides, VLDL, and, eventually, insulin resistance and diabetes.

Gretchen's postprandial diet experiment II

I previously posted Gretchen's postprandial diet experiment, in which she consumed a low-fat diet for a day, followed by a low-carbohydrate diet for a day. Grethen monitored blood glucose and triglycerides with fingerstick checks. (Blood glucose can be checked on any widely available glucose monitor; triglycerides can be monitored with the Cardiochek device.)

Let's now discuss what happened.

On the low-carb, high-fat day, there was an initial surge in triglycerides to 250 mg/dl late morning, followed by a secondary peak several hours following dinner. Because fat is mostly triglycerides, Gretchen's high-fat (sausage, bacon, butter, whole-fat yogurt) breakfast provided a large quantity of triglycerides that needed to be absorbed. This generally occurs over approximately 6 hours, varying depending on body weight, how accustomed you are to fat, activity level during the day, the kind of fat in the meal. The high content of saturated fat in Gretchen's high-fat breakfast likely caused the somewhat slower drop in triglycerides over approximately 7 1/2 hours.

As Gretchen herself had noted, triglycerides the following day were lower, a typical low-carb response. Blood sugar throughout showed only minor variation, with only small postprandial increases.

Thus, Gretchen experienced what we'd expect with a low-carb, high-fat diet: an initial high surge in triglycerides, followed by a decline in fasting levels, while blood sugar shows a normal contour.







Now, the more confusing low-fat experience:



Blood glucose makes a striking peak at 200 mg/dl after the low-fat breakfast of pasta and rice, in contrast to the low-carb breakfast. Triglycerides behaved very differently from the low-carb experiment: While there was no initial postprandial surge, there was a late surge developing 6-24 hours later. The late surge continued into the next day, with fasting levels the following morning (210 mg/dl) exceeding the starting triglyceride level (60 mg/dl).

The one potentially confusing aspect of all this is Gretchen's late rise in triglycerides on the low-fat diet. This phenomenon is due to something called de novo lipogenesis, or the liver's conversion of carbohydrates to triglycerides that occurs when an excessive carbohydrate load comes through diet. Because the human body cannot store anything beyond a minor quantity of carbohydrates (as glucose and glycogen), carbohydrates are converted to fats.

Another factor causing the late triglyceride increase is insulin resistance, given the high blood sugar response. When insulin resistance is present, the activity of the enzyme, lipoprotein lipase, is reduced. Less lipoprotein lipase activity allows slower VLDL degradation, allowing VLDL (and thereby triglycerides contained in VLDL) to "stack up" in the blood. Thus, the higher triglycerides late after eating and into the next morning.

One issue to be aware of: Acute responses can differ from chronic responses. In other words, had Gretchen had the luxury (and time and money) to conduct the experiment over, say, 4 weeks, rather than a single day, there would be somewhat different responses. The best data on this come from Dr. Jeff Volek of the University of Connecticut, in which 4 weeks of low-carbohydrate eating modify fasting and postprandial responses over time.

Several conclusions can be made from Gretchen's experience:

1) Low-carb, high-fat acutely generates extravagant postprandial triglyceride responses.
2) Low-fat causes a late triglyceride surge and higher fasting triglycerides.
3) Low-fat leads to high blood sugars and, by implication, diabetes.


Both the low-carb and the low-fat responses are undesirable, both leading to increased risk for heart disease. Which is worse? I believe that low-fat is more destructive, since it leads over time to both high triglycerides and diabetes, while low-carb/high-fat only leads to postprandial triglyceride surges, at least acutely.

How to best balance the responses to reduce risk for heart disease? That's a discussion for future.


Again, my thanks to Gretchen and the substantial amount of effort that went into generating these numbers. More of Gretchens' own writing can be found on her blogs:

A wheat-free 2010

A Heart Scan Blog reader sent this fascinating description of his wheat-free adventure.

Whenever I discuss this notion of going wheat-free and the incredible health effects that develop, I invariably receive comments or emails saying something like "I eat wheat and feel fine. That can't be true." The problem is that not everybody needs to go wheat-free. 20-30% of people can include wheat in their diet and suffer little more than weight gain, some not at all.

But stories like Michael's (below) are commonplace in my experience. I've had many patients who, at first, refused to believe that wheat exposure might be the underlying cause for health struggles. But they finally give it a try and find that rashes, arthritis, acid reflux, irritable bowel symptoms, mood swings, anger, etc. are miraculously improved or gone.

Anyway, hear what Michael has to tell us:


Dr. Davis,

I want to thank you. I was browsing the web a while back and happened to stumble upon your blog post about wheat belly. The first thing that caught my attention was that I thought you had somehow gotten a photograph of me. The young man you posted an image of looked exactly like me. So I read what you had to say. After reading, I thought "Four weeks isn’t so bad. I think I can handle this."

It has now been nine weeks and all I can say is that I am completely amazed. Let me say first that twice in the past twenty years I have been tested for allergies. The first time I was tested I showed a slight reaction to Timothy Grass, but not enough to cause me any problems. The second testing I did not show a reaction to anything. So, I have always assumed that my chronic sinus problem were due to sensitivities to environmental pollutions. Now I am not so sure. I would like to list for you everything that has happened to me since I eliminated wheat from my diet.

1. I have lost a total of 12 pounds in the last 9 weeks.
2. I have lost 1 ¼ inches of belly fat
3. I have lost a tremendous amount of fat from my neck.
4. My entire life I have had problems with oily hair. I could wash my hair and three hours later I looked as if I hadn’t washed in a week. Now my hair stays clean and soft for two to three days without shampoo.
5. My hair was always flat and stringy. Now it has lots of body.
6. I used to have thick layers of dry skin on my scalp. It would come loose in chunks as large as a fingernail. That dry scalp is gone.
7. I used to have dry flaky skin that seemed to secrete oil. That no longer happens. My skin is now soft and smooth.
8. I have lived with bad acne for at least 35 years. Now it is hard to find a pimple on my body.
9. I have always had to fight dehydration. That is no longer a problem.
10. I used to drink two large cups of coffee every morning just to be able to function. I now have enough energy that I have eliminated caffeine from my diet.
11. I sleep more soundly than ever before and my dreams are clear and vivid.
12. My thought processes are more active and clear than they have ever been.
13. My chronic sinus issue is now a thing of the past.
14. I used to have problems with getting the “shakes” if I had gone more than a couple of hours without eating. It was as if I was suffering from low blood sugar. I would even be afraid that I would pass out. Now all I feel is hunger. I can go all day without eating and never feel in danger of losing consciousness.


Today is Thursday. This past Monday my wife and I were eating out and I ordered a burger without a bun. What I didn’t realize was that the burger would arrive covered in onion rings. I knocked the mountain of onion rings onto the plate but there were still a couple that were embedded in the cheese. I decided, what the hell, a couple of onion rings shouldn’t make that much of a difference. I will not make that mistake again anytime soon. Within 30 minutes I felt like there was a steel spike going through my left eye socket. I don’t remember ever being in that much pain. My sinuses were exploding. This morning, as I write this, I still feel the vestiges of that pain. Just enough that I know it is there. But after two and a half days, I am at least able to function again.

I owe you a debt of gratitude. You may have just saved my life. In the very least you have given me the means to improve my life in ways that I never thought possible.

Thank you so much,
Michael B.



Now, if wheat exposure can do that in Michael, what damage can it do in other people?

Personally, I previously experienced many of the same symptoms that Michael suffered, all gone with wheat elimination.

My advice: If you have any inkling that you might have a wheat sensitivity, make a New Year's resolution to stay wheat-free for 4 weeks and see whether you can feel any difference. Not everybody will, but many will be telling us about the dramatic health turnarounds they experienced.

Lipoprotein lipase and you

Lipoprotein lipase can make the difference between having heart disease and not having it. Having sky-high triglycerides or normal triglycerides. It can mean dinner hanging around for over 12 hours in the bloodstream, rather than the usual 4-6 hours.

If you take niacin, you must exercise

We use a lot of niacin in the Track Your Plaque program.

Niacin:

--Increases HDL and shifts HDL towards the large, protective fraction

--Reduces small LDL--In fact, niacin is the best treatment we have to reduce small LDL after wheat elimination and carbohydrate reduction.

--Reduces fasting and postprandial (after-eating) triglycerides

--Reduces heart attack risk by 20-28%--even as a sole agent.


But . . . niacin also triggers higher blood sugar because it partially blocks the effects of insulin (insulin "resistance").

While the net effect of niacin remains positive, the provocation of insulin resistance is not such a good thing. Can it be minimized or eliminated?

Yes, through exercise. Here's one interesting observation in obese (BMI 34.0), sedentary men given placebo, exercise, niacin (1500 mg Niaspan, once per day), or niacin + exercise:





From Plaisance et al 2008.

Blood was drawn following a high-fat meal challenge. (Yes, a high-fat challenge, not a carbohydrate challenge. In this study, there were only 17 grams carbohydrates in the test meal, but 100 grams fat. More on this in future.) Exercise consisted of walking for 50 minutes at a moderate pace one hour prior to the meal challenge.

You can see from the graph that exercise partially corrected the increased insulin level provoked by niacin.

Judging from this and other studies, exercise can help minimize the insulin-blocking effects of niacin. It doesn't take much, just moderate exercise for at least 30 minutes.

Adequate sleep can also help, since sleep deprivation is a potent trigger for insulin resistance, only worsened in the presence of niacin. Vitamin D supplementation to achieve desirable blood levels (which I define as 60-70 ng/ml) is also an effective means to minimize this effect.
