series on stubborn weight loss, nosotros talked most nutrient deficiencies every bit possible roadblocks to losing trunk fat, fifty-fifty when someone is faithfully next a low-carb, higher-fat diet. I left off proverb that at that spot are nutrients nosotros typically associate with thyroid function, too thyroid component is a huge player, non precisely inwards fatty loss, but inwards metabolism too unloosen energy generation every bit a whole. If your thyroid is on the fritz, or forces outside the thyroid gland are making it become on the fritz, fatty loss volition hold upward really difficult. So this postal service too the side past times side i volition focus on nutritional factors that help the thyroid, every bit good every bit dietary too lifestyle factors that hurt the thyroid.
I receive got had many clients who were on thyroid medication of i sort or another. It was obvious to me, however, that whatever medication they were taking was not helping, because they were silent overweight, depressed, fatigued, too had other signs too symptoms of depression thyroid function. To my astonishment, these people were typically dumbfounded past times my scream for them, “Do y'all recall the medication is working? Do y'all really feel any better?” (Apparently, none of their physicians had ever bothered to inquire, too the clients had never stopped to inquire themselves if they were feeling better.) The answer, which required no hesitation or deliberation on their component whatsoever, was an unqualified NO. Of class it was no. If they did experience better, too they were losing weight, they would non receive got sought my aid inwards the outset place. This isn’t rocket science, folks. If y'all are “on thyroid medication,” but y'all still experience similar dog-poo, too thence either the dose is non optimal for you, or the type of medication is non correct for you. Before nosotros tin acquire into particular on medication, though, nosotros demand to utter a fiddling chip most thyroid component inwards general, too and thence we’ll encounter where nutrients too meds tally into the picture.
Thyroid & Metabolism
The argue why salubrious thyroid component is thence crucial for effective fatty loss is that it is i of the primary things that controls your resting metabolic rate. This is the number of calories y'all burn amount of unloosen energy your trunk expends WHILE YOU DO ABSOLUTELY NOTHING. It is the amount of unloosen energy your trunk requires just to maintain you alive. (If y'all were a building, it would hold upward similar paying rent to maintain the lights on, the plumbing working, too the estrus on. The bare minimum to brand the house habitable.)
And this is why I acquire thence annoyed most the whole “calories in, calories out” thing. Differences inwards resting metabolic charge per unit of measurement job organisation human relationship for why i person’s trunk “burns,” say, 200 calories spell they sit down on their arse watching TV, too someone else’s trunk only burns 50. If y'all receive got struggled with fatty loss at whatsoever betoken inwards your life, y'all receive got witnessed this fourth dimension too again: friends too loved ones who eat far to a greater extent than than y'all do, too who exercise far less than y'all do (perhaps non at all!), yet they weigh less than y'all do. It is PAINFUL. It is FRUSTRATING. It is NOT FAIR. And some of it—maybe non all of it—but some of it, has to do with your thyroid.
As I receive got written most inwards other posts, dedicated physical exercise burns startlingly few calories. You mightiness feel similar you’re expending a ton of energy, but anything y'all accomplish inwards the gym (or playground, park, or basement workout area) is small potatoes compared to how your trunk is processing too partitioning unloosen energy the residue of the day—all the hours upon hours during which y'all are not actively engaged inwards running, swimming, lifting, tennis, s-e-x, etc. This is what the CICO-paths never seem to admit when they utter most the demand to “eat less too displace more.” Especially the “move more” part. Why should I have to displace to a greater extent than inwards monastic tell to expend the same amount of energy someone else’s trunk expends by default?
Why is it that some people’s bodies Some of our thermostats are precisely laid a fiddling cooler. Our bodies run slower, too this includes all the unseen cellular processes going on within us all the fourth dimension (i.e., the resting metabolic rate). After nosotros encompass the ins & outs of thyroid inwards this postal service too the side past times side i or two, we’ll hold off at some other way to increment the metabolic rate, but for now, let’s remain inwards thyroid land.
Here are some signs & symptoms y'all mightiness experience if your thyroid—or the accessory glands that ship regulatory feedback to/from the thyroid—are non surgery optimally. (There are many more; this is the curt list):
Always mutual frigidity (especially the hands & feet) | Depression |
Low trunk temperature (oral or axillary/armpit) | |
Fatigue; depression unloosen energy levels | Low blood pressure |
Chronic constipation | Dry skin |
Elevated LDL | Weight gain (or difficulty losing weight) |
Hair loss | Deep vocalism (in females) |
YOU DO NOT FEEL YOUR BEST AND YOU KNOW IT’S NOT NORMAL TO FEEL SO LOUSY!! | |
The mutual frigidity trunk temperature, constipation, depression blood pressure, depression pump rate, and, of course, weight gain/difficulty losing weight all betoken to the critical role of thyroid hormone inwards controlling the basal metabolic rate. As I explained way dorsum inwards this postal service most the large intestine, nosotros tend to recall of metabolic charge per unit of measurement inwards price of “burning calories” or losing our spare tires too saddlebags. But metabolic charge per unit of measurement really agency the charge per unit of measurement at which the trunk does precisely most everything. People with depression thyroid tend to experience sluggishness/slowness all over their body: depression unloosen energy levels, depression resting pump rate, depression blood pressure. As for ever feeling cold, the trunk is thence sluggish that it fails fifty-fifty to estrus itself efficiently. The constipation shows us that the displace of waste materials through the colon is yet another thing that slows downwards from depression thyroid. Depression is probable the termination of reduced mental energy, which goes hand-in-hand with the physical fatigue. The elevated LDL is due to thyroid hormone beingness required for proper surgery of the LDL receptor. Sub-optimal receptor component à LDL volition accumulate inwards the blood.
PLEASE NOTE, HOWEVER: You don’t receive got to receive got all of these symptoms to receive got depression thyroid function. H5N1 few of them, if they are specially debilitating too y'all know y'all precisely don’t experience your best, should hold upward plenty to warrant getting your thyroid hormone levels tested. (More on this side past times side time, because, unfortunately, very few physicians receive got any clue at all when it comes to interpreting thyroid lab values.)
How the Thyroid Works
These days, it seems similar y'all can’t walk 10 feet without bumping into someone who is either already on exogenous thyroid hormone, or who thinks they should hold upward on thyroid hormone. However, it’s really rare for something to hold upward incorrect with the thyroid gland, itself. Like whatsoever other glands—the adrenals, the pituitary, the ovaries, the testes—the thyroid doesn’t do a whole lot on its own. It kicks into activity upon receiving signals from elsewhere in the body. In the instance of the thyroid, which is located inwards the anterior part of your throat/neck (actually, it wraps around the windpipe, precisely below the Adam’s apple), these signals come upward from the hypothalamus too the pituitary gland (both located inwards the brain). The hypothalamus secretes thyrotropin releasing hormone (TRH), which tells the pituitary to release thyroid stimulating hormone (TSH), too TSH tells the thyroid to secrete thyroxine (T4) too tri-iodothyronine (T3). The thyroid gland secretes mostly T4, too precisely a little amount of T3. T3 is considered “active thyroid hormone.” (T4 is far less potent.) The bulk of T3 is generated exterior the thyroid gland, when other tissues convert T4 into T3.
In monastic tell to start getting an appreciation for nutrients involved inwards these processes, let’s interruption things downwards a bit.
Most hormones too neurotransmitters are proteins. As such, they are made out of amino acids. For example, tryptophan is the edifice block for serotonin too melatonin; phenylalanine too tyrosine are edifice blocks for dopamine, adrenaline, too noradrenaline. Tyrosine is also the edifice block for thyroid hormone.
The “4” too “3” inwards T4 too T3 come upward from iodine. T4 contains four iodine atoms; T3 contains 3 iodine atoms. (Sweet! I bet at to the lowest degree one individual out at that spot didn’t know this. Ya’ larn something novel every day!) The enzyme that removes i iodine atom from T4, thereby turning it into T3, requires selenium every bit a cofactor. Now y'all know why iodine too selenium are mentioned when thyroid component is discussed.
Another nutrient required for salubrious thyroid component is vitamin A. I precisely learned this, myself. I had read hither too at that spot that vitamin H5N1 was of import for thyroid health, but I only latterly took the fourth dimension to inquiry the details. (Mostly out of self-interest. Yours really is experiencing some seriously infuriating thyroid “stuff,” too if at that spot is one affair that could perchance acquire me to choke downwards some horrid, horrid cod liver fossil oil [high inwards vit A], it is the prospect of feeling better.)
Here’s a fiddling chip of what I found:
Vitamin H5N1 is required for activation of thyroid hormone receptors, too insufficient vitamin H5N1 may depress thyroid function. (So it’s a double-whammy.) Animal models receive got shown that vitamin H5N1 deficiency interferes with thyroid wellness starting farther upstream, inwards the pituitary gland. Vitamin H5N1 insufficiency increases pituitary synthesis too secretion of TSH, increases the size of the thyroid gland, too reduces uptake of iodine past times the thyroid gland. (We’ll utter to a greater extent than most TSH inwards a bit.)
Vitamin H5N1 given alone, fifty-fifty inwards the absence of increased iodine, has demonstrated a positive acquit on on thyroid gland component too size. Vitamin H5N1 supplementation was shown to reduce serum TSH levels too increment T3 inwards premenopausal women, including a cohort of obese women, with whom subclinical hypothyroidism is rampant. Among children with goiter (a sign of freakishly severe iodine deficiency), living inwards areas where iodine deficiency disorders are prevalent, the greater the severity of vitamin H5N1 deficiency, the greater their thyroid gland book too the higher their TSH levels. Compared to placebo, supplemental vitamin H5N1 significantly reduced median TSH too the charge per unit of measurement of goiter.

Completely lost? Don’t worry; thence are most doctors! |
But agree the phone! Before y'all become running out to purchase a vitamin H5N1 supplement, hold upward careful. High doses may really decrease thyroid function. HYPER-thyroid patients receive got been successfully treated with high doses of vitamin A, resulting inwards decreased symptoms of an overactive thyroid too a decreased metabolic rate. (NOT what nosotros desire if we’re HYPO-thyroid!!) It appears that the outcome of vitamin H5N1 on thyroid function—like the outcome of precisely most all vitamins too minerals—is a U-shaped curve: every bit good fiddling causes problems, but every bit good much tin also hold upward harmful. It is in all likelihood unopen to impossible to “overdose” on vitamin H5N1 via foods, although it mightiness hold upward possible with strong supplements. (Forget most that stupid polar acquit liver report everyone’s ever going on most when they utter most vitamin H5N1 “toxicity.” When’s the side past times side fourth dimension y'all programme on gorging on polar acquit liver?)
Of course, overt vitamin H5N1 deficiency is associated with the developing earth far to a greater extent than than with industrialized nations. (It’s the leading crusade of blindness worldwide.) BUT, it may good hold upward that a pregnant share of the “First World” population is living with some marker of insufficiency. People vary inwards their capacity to convert works life precursor carotenes (the materials y'all abide by inwards carrots, pumpkin, sweetness potatoes, too leafy greens), into truthful vitamin A. This may non hold upward an number for people who follow omnivorous diets too eat adequate pre-formed vitamin A, but it may hold upward problematic for vegetarians too vegans. Obviously, the vegetarian/vegan pitfall probable doesn’t apply to y'all if you’re next a LCHF diet. (Although at that spot are, inwards fact, some lacto-ovo vegetarians doing LCHF.) So fifty-fifty if y'all eat large amounts of foods high inwards beta-carotene, y'all mightiness non hold upward making the conversion effectively. Moreover, every bit if the human relationship betwixt vitamin H5N1 status too thyroid component wasn’t complicated enough, sluggish thyroid component may impair the conversion of carotenes to truthful vitamin A, too y'all demand vitamin H5N1 for salubrious thyroid receptor function, creating yet some other double-whammy scenario for a salubrious thyroid.
It is possible to eat a LCHF diet too silent hold upward a fiddling depression inwards vitamin A. Some foods are higher than others, too some of the animate beingness foods that are considered rich sources mightiness non hold upward every bit rich every bit nosotros think, depending on the animals’ diets. (Egg yolks, butter, too other dairy fats come upward to mind, every bit do beef too lamb tallow. The yellowish color inwards these fats comes from carotenoids inwards the grass, which bio-accumulate every bit vitamin H5N1 inwards the animals’ fat. So fifty-fifty though I stand upward past times what I’ve said inwards the past times most all grass-fed/pastured/organic non beingness the most of import affair inwards the world, if y'all are specifically looking to increment your vitamin H5N1 intake, it wouldn’t hold upward a bad thought to pony upward precisely a fiddling extra cash for the grass-fed stuff, too hold upward sure to eastward some of the fat. [Egg yolks from pastured hens volition receive got some vit A, but the yellowish is also due to lutein.])
Cruciferous Vegetables:
Don’t Ban Broccoli!
You may receive got heard something most sure vegetables interfering with thyroid function. There is some truth to this, but earlier y'all become excommunicating broccoli, cauliflower, too Brussels sprouts from your diet, allow me ‘splain how this really works inwards the existent earth too the human body.
The category of cruciferous vegetables is known to comprise goitrogenic compounds that may interfere with salubrious thyroid function. Goitrogens inhibit the uptake of iodine past times the thyroid gland, leading to decreased production of thyroid hormone. That is a chip of a bummer, because with the cruciferous vegetables are some Paleo, Primal, too LCHF staples: broccoli, cauliflower, Brussels sprouts, kale, too all forms of cabbage. What?! No to a greater extent than cauliflower “rice?” No to a greater extent than Brussels sprouts roasted with bacon? No to a greater extent than kale chips? And nosotros demand iodine, selenium, too vitamin H5N1 for thyroid function? Amy, are y'all telling us nosotros are supposed to eat zilch but liver too seaweed, with Brazil nuts for dessert? That’s it; I quit! I’m gonna hitting upward the nearest Shoney’s breakfast buffet, too at that spot are not plenty pancakes too syrup inwards the world to feed the hole that has opened inwards my soul! REMAIN CALM!
It’s all good. Here’s the deal:
These vegetables are typically non a problem, provided y'all eat them cooked. And really, a small amount of them raw is okay. If y'all similar coleslaw, or y'all desire to receive got some raw broccoli too cauliflower dipped inwards guacamole, hummus, or dip, every bit a crudité, no problem; precisely don’t become crazy. All the vegans (and fifty-fifty some omnivores) who recall they’re doing themselves proficient past times having a raw kale smoothie every day? BAD THYROID JUJU! There’s a argue raw kale tastes thence bitter too foul all past times itself—probably because we’re non supposed to eat it! (Don’t inquire me most raw liver. Whatever floats your boat…) Raw kale smoothies are fifty-fifty worse thyroid juju for vegetarians too vegans because they are at higher gamble for iodine deficiency, too the cruciferous vegetable “problem” is really only a job for people who are iodine deficient. The richest sources of dietary iodine are shellfish, seaweed, too dairy products, with describe amounts inwards iodized salt. (A vegan’s only choices at that spot are seaweed too salt. Plus, soy is a huge goitrogen, thence twain an iodine deficiency with large intakes of soy, too it’s a recipe for thyroid disaster.)
However, it is my belief that iodine insufficiency is rampant these days, even with omnivores. (Maybe non overt, goiter-causing levels of deficiency, but sure enough insufficiency.) Where the heck is anyone getting iodine anymore? Some people eat lots of shellfish; others eat none. Some people occupation seaweed inwards their cooking; others occupation none. Some people become out of their way to occupation only “natural” salt, which is not fortified with iodine. Some people eat dairy, but many inwards the Paleo crowd avoid it. Dairy products are non naturally high inwards iodine anyway. Trace amounts of iodine that brand their way into milk, cheese, yogurt, etc., come upward from the iodine that is used to sterilize the cows’ teats prior to milking. Trust me on this; I’ve worked on a dairy farm. Beyond this, on some farms, the cows’ feed is supplemented with kelp, which is a non bad root of iodine. (I similar to occupation this sprinkled inwards omelets.) On the farm I worked at, the dairy herd was alone grass-fed, except for a really little amount of grain that was used to maintain them placid too happy inwards the milking parlor. It is this feed that was supplemented with kelp. I recall some farms also occupation kelp-enriched feed for their laying hens, which would impart a chip of iodine to the yolks of those eggs.
My betoken is, I precisely don’t encounter how most people are getting sufficient iodine these days. (This is made fifty-fifty worse past times the prevalence of other element of group VII elements that give the axe iodine inwards the body. More on this side past times side time.) So it’s non that nosotros should eliminate cruciferous vegetables from our diet. (But if y'all want to, hey, no peel off my back.) What nosotros could do if nosotros desire to locomote along enjoying yummy LCHF dishes similar cauliflower couscous too parmesan roasted broccoli, is eat them cooked too brand sure we’re iodine replete. (More on that inwards a sec.) Also, if you’re taking an iodine supplement, precisely to hold upward cautious, y'all mightiness desire to receive got it with a repast that doesn’t comprise cruciferous vegetables. For example, receive got it inwards the morning time if you’re having scrambled eggs too sausage, or a veggie omelet with non-cruciferous veg. Don’t receive got it at dinner with your steak too a gigantic pile of broccoli. (I don’t recall this is that big a deal, though, especially because most iodine supplements are pretty high-dose. It’s precisely something to recall about, if y'all desire to hedge your bets.)
Why would y'all fifty-fifty want to eat cruciferous vegetables raw, anyway? I mean, coleslaw is piece of cake to chew because the cabbage sits for a spell inwards some type of vinegar or mayo-based dressing, too softens upward a bit. But raw kale? Brussels sprouts? Have y'all ever tried to eat raw Brussels sprouts? Like I said inwards a one lab that evaluates these tests, whole-body iodine sufficiency is reached when 90% of the iodine is excreted. [And maintain inwards mind, the thyroid isn’t the only component of the trunk that uses iodine. Other places where iodine concentrates are the breasts, the ovaries, brain, lacrimal glands (which make tears), salivary glands, too gastric mucosa. (The latter 3 are telling: iodine is antiviral, antiparasitic, too antimicrobial, which is why they sterilize your arm with iodine earlier y'all donate blood. Saliva, tears, too gastric secretions are 3 of our strongest natural defenses against invading pathogens.])
Okay. That is way to a greater extent than than anyone wanted to know most nutrients too the thyroid. Next time, we’ll acquire into testing & interpreting thyroid hormone levels, too I’ll betoken y'all toward some resources y'all tin occupation to educate yourself if you’ve been working with an MD who has proven incapable of helping you. We’ll also hold off at other factors, apart from nutrient deficiencies, that tin interfere with salubrious thyroid function. (Example: fluoride inwards the water? Bromide every bit a dough conditioner? In my opinion, not among world health’s greatest achievements!)
In the meantime, I highly recommend watching this video on the importance of iodine for the whole body, non precisely the thyroid. It volition give y'all a strong appreciation for precisely how deficient most people in all likelihood are, every bit good every bit the critical role of iodine for overall health, especially that of the breasts & ovaries. (Hyperinsulinemia isn’t the only affair driving pectus & ovarian cysts, ladies.) You volition also larn most the interaction betwixt thyroid hormone too estrogen, which is with the topics we’ll hold off at side past times side time, too explains why women experience thyroid dysfunction thence much to a greater extent than than men do. (Unfortunately, whoever filmed the video kept the photographic boob tube camera on the MD most of the time, thence nosotros missy out on seeing a lot of the slides, but it is silent worth watching/listening to.)
