Thyroid, Blood Sugar, and Metabolic Syndrome


Last updated on

This article is part of a special report on Thyroid Disorders. To see the other articles in this series, click here.

According to the American Association of Clinical Endocrinologists, 27 million Americans suffer from thyroid dysfunction – half of whom go undiagnosed. Subclinical hypothyroidism, a condition in which TSH is elevated but free T4 is normal, may affect an additional 24 million Americans. Taken together, more than 50 million Americans are affected by some form of thyroid disorder.

Metabolic syndrome (MetS), also affects 50 million Americans, and insulin resistance, one of the components of metabolic syndrome, affects up to 105 million Americans. That’s 35% of the population.

Metabolic syndrome has become so common that it’s predicted to eventually bankrupt our healthcare system. Both metabolic syndrome and insulin resistance are risk factors for heart disease and diabetes, two of the leading causes of death in the developed world. It’s also closely related with diabesity.

With such a high prevalence of both thyroid dysfunction and metabolic syndrome, you might suspect there’s a connection between the two. And you’d be right.

Studies show an increased frequency of thyroid disorders in diabetics, and a higher prevalence of obesity and metabolic syndrome in people with thyroid disorders.

That’s because healthy thyroid function depends on keeping your blood sugar in a normal range, and keeping your blood sugar in a normal range depends on healthy thyroid function.

Thyroid, Blood Sugar, and Metabolic Syndrome

Metabolic syndrome is defined as a group of metabolic risk factors appearing together, including:

Metabolic syndrome is caused by chronic hyperglycemia (high blood sugar). Chronic hyperglycemia is caused by eating too many carbohydrates. Therefore, metabolic syndrome could more simply be called “excess carbohydrate disease”. In fact, some researchers have gone as far as defining metabolic syndrome as “those physiologic markers that respond to reduction in dietary carbohydrate.”

When you eat too many carbs, the pancreas secretes insulin to move excess glucose from the blood into the cells where glucose is used to produce energy. But over time, the cells lose the ability to respond to insulin. It’s as if insulin is knocking on the door, but the cells can’t hear it. The pancreas responds by pumping out even more insulin (knocking louder) in an effort to get glucose into the cells, and this eventually causes insulin resistance.

Studies have shown that the repeated insulin surges common in insulin resistance increase the destruction of the thyroid gland in people with autoimmune thyroid disease. As the thyroid gland is destroyed, thyroid hormone production falls.

How Low Blood Sugar Affects the Thyroid

But just as high blood sugar can weaken thyroid function, chronically low blood sugar can also cause problems.

Your body is genetically programmed to recognize low blood sugar as a threat to survival. Severe or prolonged hypoglycemia can cause seizures, coma, and death. When your blood sugar levels drop below normal, your adrenal glands respond by secreting a hormone called cortisol. Cortisol then tells the liver to produce more glucose, bringing blood sugar levels back to normal.

The problem is that cortisol (along with epinephrine) is also a sympathetic nervous system hormone involved in the “flight or fight” response.

This response includes an increase in heart rate and lung action and an increase in blood flow to skeletal muscles to help us defend against or flee from danger. Cortisol’s role is to increase the amount of glucose available to the brain, enhance tissue repair, and curb functions – like digestion, growth and reproduction – that are nonessential or even detrimental in a fight or flight situation.

Unfortunately for hypoglycemics, repeated cortisol release caused by episodes of low blood sugar suppresses pituitary function. And as I showed in a previous article, without proper pituitary function, your thyroid can’t function properly.

Together, hyperglycemia and hypoglycemia are referred to as dysglycemia. Dysglycemia weakens and inflames the gut, lungs and brain, imbalances hormone levels, exhausts the adrenal glands, disrupts detoxification pathways, and impairs overall metabolism. Each of these effects significantly weakens thyroid function. As long as you have dysglycemia, whatever you do to fix your thyroid isn’t going to work.

How Low Thyroid Function Affects Blood Sugar

We’ve seen now how both high and low blood sugar cause thyroid dysfunction. On the other hand, low thyroid function can cause dysglycemia and metabolic syndrome through a variety of mechanisms:

  • it slows the rate of glucose uptake by cells;
  • it decreases rate of glucose absorption in the gut;
  • it slows response of insulin to elevated blood sugar; and,
  • it slows the clearance of insulin from the blood.

These mechanisms present clinically as hypoglycemia. When you’re hypothyroid, your cells aren’t very sensitive to glucose. So although you may have normal levels of glucose in your blood, you’ll have the symptoms of hypoglycemia (fatigue, headache, hunger, irritability, etc.). And since your cells aren’t getting the glucose they need, your adrenals will release cortisol to increase the amount of glucose available to them. This causes a chronic stress response, as I described above, that suppresses thyroid function.

How to Keep Your Blood Sugar in a Healthy Range

It’s important to understand that whether you have high or low blood sugar, you probably have some degree of insulin resistance. I described how high blood sugar causes insulin resistance above. But insulin resistance can also cause low blood sugar. This condition, called reactive hypoglycemia, occurs when the body secretes excess insulin in response to a high carbohydrate meal – causing blood sugar levels to drop below normal.

In either case, the solution is to make sure your blood sugar stays within a healthy range. There are two targets to consider. The first is fasting blood glucose, which is a measure of your blood sugar first thing in the morning before eating or drinking anything. I define the normal range for fasting blood glucose as 75 – 95 mg/dL. Although 100 is often considered the cutoff for normal, studies have shown that fasting blood sugar levels in the mid-90s were predictive of future diabetes a decade later. And although 80 mg/dL is often defined as the cutoff on the low end, plenty of healthy people have fasting blood sugar in the mid-to-high 70s (especially if they follow a low-carb diet).

The second, and much more important, target is post-prandial blood glucose. This is a measure of your blood sugar 1-2 hours after a meal. Several studies have shown that post-prandial blood glucose is the most accurate predictor of future diabetic complications and is the first marker (before fasting blood glucose and Hb1Ac) to indicate dysglycemia.

Normal post-prandial blood sugar one to two hours after a meal is 120 mg/dL. Most normal people are under 100 mg/dL two hours after a meal.

Now that we know the targets, let’s look at how to meet them. If you’re hypoglycemic, your challenge is to keep your blood sugar above 75 throughout the day. The best way to do this is to eat a low-to-moderate carbohydrate diet (to prevent the blood sugar fluctuations I described above), and to eat frequent, small meals every 2-3 hours (to ensure a continuous supply of energy to the body.

If you’re hyperglycemic, your challenge is to keep your blood sugar below 120 two hours after a meal. The only way you’re going to be able to do this is to restrict carbohydrates. But how low-carb do you need to go? The answer is different for everyone. You figure your own carbohydrate tolerance by buying a blood glucose meter and testing your blood sugar after various meals. If you’ve eaten too many carbs, your blood sugar will remain above 120 mg/dL two hours after your meal.

I highly recommend you pick up a blood glucose meter if you have a thyroid and/or blood sugar problem. It’s the simplest and most cost-effective way to figure out how much carbohydrate is safe for you to eat. There are tons of meters out there, but one that gets a lot of good recommendations is the ReliOn Ultima. It’s pretty cheap, and the test strips are also cheap, which is where the major expense lies.

Finally, if you have poor thyroid function it’s important that you take steps to normalize it. As I’ve described in this article, the cycle works in both directions. Dysglycemia can depress thyroid function, but thyroid disorders can cause dysglycemia and predispose you to insulin resistance and metabolic syndrome.

Maintaining healthy blood sugar is not only critical for thyroid health, it’s essential for overall health. Sadly, half of Americans has or is at risk of having diabetes, with one-third diabetics unaware that they have it. 

There are many causes of high blood sugar. One of the most significant but least-known is nutrient deficiency. Several vitamins and minerals are required for proper blood sugar regulation, and the majority of Americans don’t get enough of several of these micronutrients

This is where smart supplementation can play a role—and it’s why I created the Adapt Naturals Core Plus bundle. It’s a daily stack of 5 products designed to restore optimal nutrient levels so your body can function as it was intended to, and you can feel and perform your best. 

From metabolism-boosting vitamins and minerals like vitamin B12, folate, magnesium, and vitamin D, to phytonutrients like bioflavonoids, carotenoids, and beta-glucans, Core Plus has you covered.

  1. I have often had a mild feeling like I’m going to throw up in my throat feeling and its been going on subtly for about 6 years on and off and I found out in 2012 I crashed on the Synthetic T3 now I’m on Natural Desiccated Thyroid and feeling almost completely better. But the last month I have been increasing in that same symptom and it has been stronger and I haven’t been feeling well. My husband said it’s a symptom of diabetes so had me take 2 tbs of blackstrap molasses and it subsided. We believe now I should get a blood test for diabetes, I never thought I would ever have a problem like this although when I eat carbs or sugar my heart beats fast for me. I really want to rid my house of all carbs again breads and potatoes. I guess I will have to but a glucometer to test.
    Also my husband is hypoglycemic and he eats bread at night to help him sleep and I know that is not a good idea since the bread makes his blood sugar low and those over the counter sleep meds are not good and the herbs don’t help at all, I suspect he has high cortisol at night because of many years of swing shift. Thank you for your time.

    • Also this is Terese again, The TSH lab showed I was normal but indeed it is not working for many people as you can see on the STTM site. Like me my Dr. said I was normal for 6 years and I had almost all the symptoms and also have adrenal fatigue.
      When I first was tested in 1993 with the TSH lab I was hypothyroid and I changed to Synthetic and crashed by around 2005 although I had symptoms all along on Synthetic like low blood pressure and the Dr’s would say I was normal but I had unexplained weight gain after being 110lbs for a long time also:
      Toe nails falling off easily when wearing too tight shoes
      Abnormally Fast Heartbeat just going up the stairs
      Hard time hiking up small Mountains, never had that before
      Decreased Strength
      Itchy legs I could dig them for sure
      Itchy ears
      Very low blood pressure basal temp 79/45
      Weight Gain
      Tired all the time
      Air hunger always felt better if we opened a window at work
      Hair loss
      Temperature going from 96-101 during the day with no cold or flu
      Bruising lightly
      Cry if I bumped myself lightly
      No desire poor hubby
      I do have ringing in my ears and for about 10 yrs
      Hard time eating breakfast
      Feeling like puking almost like when I was pregnant
      Poor memory
      Brain fog
      Poor to no interest in normal activities
      Crying over nothing
      and more but it must be getting boring 🙂

      • Hi Terese,

        I started having a LOT of what you mentioned about ten years ago. I used to be an avid hiker and biker, then I found I could never go even do my basic amount without having all sorts of those symptoms. Aside from that, I would have extreme body temperature drops the night of exercise that would send me into the shakes, then bounce back and forth mild fevers. I hit 94.7 during a bad series of episodes from one hike, but of course by the time i got to the ER it recovered into a mild fever.

        If not for being hit with bad acid reflux at the time, I never would’ve found out when I would take Tums, the shakes and uncomfortable heartbeat would ease up very quickly, from the calcium I assume.

        I went to the doctor several times trying to get to the bottom of it, but was left up a creek and couldn’t get anywhere because I had been treated for anxiety in the past, so they would not budge from the “the body does a lot of weird things when a panic attack occurs”. Right, systematically after certain types of exercise of foods? They wouldn’t test for diabetes, thyroid, or anything else, and I was pretty young so I didn’t really have my backbone yet.

        If you want to compare notes sometime, maybe it’d help.

        • hi Will
          Im sorry i didnt see your reply
          Also ive been on Natural Thyroid meds i buy myself and im feeling better esp if i stay on track with taking thyroid meds on time and eating right and supplements
          I wonder if u have thyroid n adrenal issues
          I was diagnosed with thyroid issues earlier but synthetic T4 is not working for anyone
          Go to the Stop The Thyroid Madness website
          Its the only good website for thyroid and adrenal help
          I had fevers n low temps all in one day every day and now i take Natural Thyroid n no more fever
          My temp is almost normal daily and i have had shaking with no control
          I know the mercury fillings i had is the cause
          But u have to remove them safely IAOMT Protocol but not theyre detox protocol its dangerous along with iv chelation
          Dr Andrew Hall Cutler is the only Dr i know who helps people detox safely
          But im still not willing to risk that with my health issues
          Hope this helps

      • Omgosh this is me and Im sure it all began after puberty, but my issues did not become noticeable until I had my second pregnancy I was 21 and it ended with an emergency surgery they thought I had a tuble pregnancy in stead was an otopic my over I was saved but my hormone’s were all out of wack we tried birth control pills hormone and non hormonal the shot ring patch I gained 40-60lb that year had one more misscarage and one successful pregnancy,kind of I had swelling which because of my huge weight gain the past year went unoticed till about 6 month in then was told possible toxemia but labs were fine ??till delivery all of a sudden pre-aclamcia another emergency surgery ,but this time I was blessed with my second son at 22yr old from the 2nd pregnancy to my 4th one in less than 24months I had officially gianed 80lb and had no periods or if I did It was less that 3 a year for the next 5 years now I can’t loss a pound my labs were always in normal or border line yet nothing done I eventually just gave up and live now with the constant fatigue absent mindedness now 100lb gain stomach issues bm issues exct.but I have 5 beautiful children and regular periods much heavier than the 3 day ones before all the madness 🙂 but regularly now and I’ll take it we eat very clean my kids are my everything but just today my oldest 14 this week had blood test come back with very low sugars so I’m kinda freaking praying all will be fine he has a lot of my issues but basic labs always came back in normal range he has very back acne with scares all over face and upper body I pray we haven’t missed anything by just assuming he’s fine and acne is normal 🙁

  2. I primarily eat paleo. My tryglycerides were in the 40’s last check. What worries me is my HgbA1C is 5.7. How do I get a high number here when I eat a pretty low carb diet. I’ve thought I was hypothryroid for over 10 years, but my physicians say my levels are “normal”. They are always just barely in the normal range. I eat lots of meat, take fish oil, and exercise. I think this number is still due to my hypothyroid state. What do you think??

    • Please find an integrative or functional medicine doctor who will treat you for optimal levels regarding your thyroid. What tests were done by your physician? Please look up Stop The Thyroid Madness website as well as look up Dr. David Brownstein, and Mary Shomon, for what tests are needed to fully examine if you have a thyroid condition, and what optimal levels should be. Many general practitioners and even Endocrinologists, even in this day and age, refuse to educate themselves on how to optimally recognize and treat Autoimmune Hashimoto’s and/or hypothyroidism. Many even go by just TSH results, and there millions suffering because of it! Please be your own best advocate and find a doctor who will listen to you! 😉

  3. Hi everyone, I wondered if anyone can give me some guidance on this. I am doing as suggest above, testing my blood glucose after meals to figure out carbohydrate tolerance, but am confused as to WHEN I need to test and whether the readings I get are concerning. Basically, every so often, I will test a few meals in a day after 15, 30, 45 and 60 mins and then after 2 hrs. The readings I get in the first hour can sometimes spike right up to 180 (I’ve seen 220 sometimes!), but I will usually return to a less worrying range at 2 hrs – usually around 115 if the spikes have been large. Should I be concerned about the spikes between the meal and the 2hrs reading, or is it normal to see spikes in this time period? I don’t know if I am over-concerned about the spikes or not. Anyway, any advice/ pearls of wisdom, I’d be grateful. Thanks, Jen

  4. I feel so enlightened by this article Chris.
    I have lived with hypothyroidism all my life,I’m now 44yrs old.
    When I was 15 I put on a lot of weight from binge eating disorder and depression, and blamed my thyroid condition entirely even up to today for my struggle over my figure.
    I now know it still is a major factor, but I also have to take responsibility for working with the equation also, when making food choices to keep my blood sugar stable.
    It’s good to learn that measuring blood sugar kits are not just useful for diabetics.im going straight out to buy one.
    I have been very aware for some time my link between my medication dose level and if it changes in effectiveness, the creeping nature of carb cravings that seem to occur.i find that interaction very distressing and one I’m fearful of, as DESPISE weight gain.
    Even when I get very lean the abdominal/midriff fat stubbornly remains.
    This article is great.i have learnt so much new insight.
    Thanks Jo

  5. Hi Chris,

    thank you for the very informative post, I learned a lot from reading it! I’m 25yo female endurance athlete and have been struggling with weight gain and hypothyroid/overtraining related symptoms the last 3 years. I was 47kg (162cm tall) before this nightmare began; now I’m 70kg (still 162cm)… I’ve tried thyroxine, liothyronine, the combination of the two, and armour thyroid, but so far I’ve just gained weight (way too much if u ask me) and felt awful 🙁 currently I’m on liothyronine only, the dose is 110µg.

    I eat a healthy diet, maybe too little energy but otherwise I guess it should be okay. Some 1700-1900 kcal, 200-220g CHO, 60-80g PRO, 50-70g fat a day. Training 1-2h/day (running/cycling/water running) + nonexercise activity 2-3h a day (walking/cycling to work/grocery store etc). Still gaining weight! Which makes me so unhappy, frustrated when nothing seems to work.

    My fasting blood glucose was just measured and I was shocked to see it was 6.1 mmol/l. The limits for healthy are 4.0-6.0, and they say if you have 6.1-6.9 it’s impared fasting glucose, and 7.0 or more diabetes 2.

    So, I’m asking you what do you think about my situation (diet/training regimen/thyroid/blood glucose)?

    Thank you so much if you find some time answering I really am desperate with this 🙁

  6. Chris, Thank you for this blog. I have a unique problem that no doctor (UCSF, Stanford & numerous other MD’s) cannot find the answer to. All of my test show I am in the best of health. I am a severe reactive hypoglycemic. I have hypothyroid but if I take the medicine for it I will have a hypoglycemic attack. I often go into the 20’s & 30’s, sometimes my meter only show Lo. I cannot tolerate anything with flour. If I eat breakfast (egg) I start the hypo process so I usually eat only one meal a day at night to limit the amount of attacks I have (beans soup, veggies, meat). After eating this I need some sweet like ice cream to not have an attack. I often lose part of my vision during an attack and worry about losing cognitive function. I cannot tolerate bio-identical hormones or estrogen. I am highly allergic to many medicines. After 10 years of being shuffled around I am at my wits end. I cannot use the Dexacom Meter because some of my meds will render it useless. I have neuropathy and am in pain most of the day even though I try not to be. They will not give me an alert dog because I am not diabetic. I have been told my step is the Mayo or Cleveland Clinics but I really cannot afford the time to stay there and I doubt they could do more? I guess you and some of your readers might provide the best hope for me.
    Sincerely, Janis

  7. Hello Chris.

    I am 41 years old. About a year ago, I was getting dizzy spells at work. More light headed than dizzy. I went to employee health where my BP was 180/110.

    I went home and saw the MD who put me on a Beta Blocker.It helped the BP at first but after about 4 months I started having the lightheadedness again only more severely after activity.

    He stopped the Beta and put me on an ACE inhibitor. Felt better at first, now having very high heart rates with little exertion. With that, frequent urination and lower heat tolerance. Also, the lightheadedness has returned.

    I do have reactive Hypogylcemia and was wondering if that has been the problem all along. I know low blood sugar causes high heart rate which was masked by the Beta but would it increase my BP?

    With all this has been frequent anxiety and panic attacks which I never had before a year ago. Thanks Chris.

  8. Dear Chris,
    My mother has been diagnosed as diabetic.But later the doc reduced her dose and detected low thyroid level.After taking up thyroxine her glucose level is normal since then.Do you think it wasn’t diabetics but hypothyroidism?

  9. Hi. I have hypothyroidism and im hypoglycemia since I was 15 im now 30. I have never had a bad attack until recently. My sugar dropped Severely, & I was told I went crazy/ lost it. I dont remember any of it. Is this normal. My husband of 8 years said he had tried to restrain me and I was biting him to get loose. Is this normal I feel horrible and embarrassed all at the same time. I was at my neighbors house and it just hit all I can remember is standing at the counter talking about vacation bible school and they Said next thing I was laying on their floor whispering. I had forgot to eat for two days. Is this normal for all this and the memory loss of it? Im completely still racking my brain over what I said or did is their any way of remembering? Could you please help me understand it a little better thank you.

      • It is very easy if you don’t feel hungry and don’t get any pangs, headaches or lighheadedness. That is my problem, I can go days without eating but have noticed I have an insatiable thirst.
        If I eat after forgetting for some time, I crash for at least 10-12 hours of sleep that is almost comatose if you hear my kids discribe it.

  10. I’ve had boarder line underactive thyrold for four years but when I had last blood test was told I have underactive thyrold . Now I am on medication . My problem is I keep getting low sugar .i start to feel shaking and I don’t have sugar in my tea. But when I get them I put two sugars in my tea and I can’t taste it . Told my docter but does not seem to do anything .

  11. I am always hungry and my stomache feels like a bottomless pit. i am 27. average weight. female. have not had my period in 5 months. have had issues with missed periods in the past as well (in 2013 i missed my period for 6 months as well). i eat VERY WELL. very clean. i bought a blood glucose monitor. here is an example of my blood sugar readings and i’m not sure if these fluctuations are normal: fasting blood sugar: 4.4 at 830AM. ate from 10-11:15am (steel cut oats, 2 tomatoes, mushrooms, chickpeas). reading at 11:15AM: 6.6. 11:29AM 8.3 , 11:32AM 7.7 , 11:46AM 6.7, 12:01PM 6.2, 12:24PM 5.1, 12:40PM 4.4, 12:53PM 4.3, 1:13PM 3.8.
    looks to me like these readings are way too deviated and fluctuating. please advise
    blood tests for hormones etc all came back normal. ultrasound came back normal.

  12. Dear Chris,

    I have just read through the article and am concerned as to the information you are distributing.
    Most of the information on there relating to blood sugar levels and glucose intake are incorrect.
    Too low is 1, too high is 15.
    If one has an episode of low levels we have this stuff called glucogel, goes shooting up really fast but then you have to keep monitoring it to make sure it levels out and doesn’t go down too far again.

    So why is your article stating the opposit.
    Please reply

    • i think he is talking about fasting glucose and you are talking about fasting insulin. i too, would like to know how you test for insulin as well. my glucose falls between low and high. wondering what insulin is doing. are there meters for that?

  13. I have an eating disorder so my history has been me at an average weight->underweight->gaining all plus more->underweight on low carb (30-100g/day) paleo for 3 years->gaining 50lbs in 2 months from binging on carbs/sugars (for about a month). It has been two months since gaining those initial 50+lbs and I believe I am still gaining despite eating low carb again and no longer binging (eating just over 2000 cals/day). I am only 21 and my job 5 days a week is pretty active. I know I have a compromised thyroid but have immersed myself in research for years and just cant find the culprit. Hashimotos? Just hypothyroid? Dysglcemia? I cant pin point where my blood sugar/insulin resistance is because of my starve on low carb/overeat on sugar history. So any advice on my situation would be amazing!

  14. Hey Chris! Your blog has been very informative. Due to a couple bouts of hypoglycemia about an hour or so after a meal I visited the ER in a panic. They ran a test for the thyroid and my TSH level came back at 21.92! I started on synthroid immediately the next day and am seeing an encronologist this week. I check my glucose levels frequently due to a prediabetic scare a few years back. My fasting bg is about 100 in the mornings, and typically hanging around 80-120 at any given time when I check it. Although, I do check it sometimes and have seen it as high as 150 right after some yogurt and whole grain granola, but then dropped below 120 within 10-15 mins. Doesn’t seem normal. I dieted earlier this year and lost 30 lbs, I’m a 25 year old male and weigh 205 now. I also deal with anxiety and was tying out lexapro when this first happened. No longer on lexapro it wasn’t for me. Anyways, i don’t eat just and if I do eat bread or pasta it’s whole grain. I’ve cut my meals into 4-6 smaller meals and always snacking in fear or getting low again, but now seeing the higher numbers that freaks me out too. I just had blood work done from my GP at my request to rule out anything else too and should get the results this week as well. Your thoughts would be greatly appreciated! Thanks!

  15. Kris, I have been dealing with a nasty case of insulin resistance, which has made weight loss nearly impossible. My glucose numbers always look great, but it is my insulin numbers that do not. I have high insulin while fasting and high insulin at 2HPP. It is a slow process to repair and my fear is that any straying to the dark side (even fruit sugars) will cause my insulin to start screaming again. After 8 weeks on vegetables (no starchy ones) and protein, my insulin was still high. So, tracking blood glucose isn’t always going to show the existence of insulin resistance.

  16. Hello, After 3 previous episodes of hyperthyroidism I have now been on a maintenance does of Carbimazole for the past 2 years of 2.5mg. During the last 2 years my tsh and t4 levels have been consistently around 2 and 9 respectively. My Endocrinologist who has just discharged me from his care says my results are `perfect`. However I do not feel myself most of the time – agitated, tired, irritable,variable pulse rate (from 50bpm to 120), hungry even after just eating), non existent sex drive, cold hands, muscle pain, and general feeling of malaise. I am very worried that my Endocrinologist has discharged me and feel his care has been poor since I was first diagnosed with hyperthyroidism 10 years ago. I have also recently been diagnosed with `pre-diabetes` and wonder if there is a link. I try to keep myself fit and have a good diet. I am 66 years old and not overweight. Any advice you can offer would be very gratefully received.

  17. Hi Chris,
    To start of I’m a huge fan of your work! Kudos to you for all you do! After being a highly (emotionally, physically and psychologically) stressed raw vegan for over a year I switched cold turkey to paleo diet (craving organ meats, dairy, cream ,butter in huge quantities) and it is then that my metabolism got totally messed up, started gaining fat like crazy, feeling depressed, lethargic. Later on found out im intolerant to dairy which contibuted highly to inflammation and weight gain. Kicked off dairy, slowly transitioned to keto like diet to lose the rest of the weight and get rid of inflammation, normalize thyroid and adrenals..
    I am pretty sure it was my adrenals that have been suffering which then translated to low thyroid symptoms (depression, lethargy, weak dry hair, weight gain) and the whole restrictive raw diet only aggravated the whole situation resulting in huge deficiencies. Now, I’ve been meaning to ask you, if one is still experiencing some of the symptoms of a metabolic syndrome but has been on a low carb, keto like diet for few months already (I did notice an improvement but the higher body fat in abdominal area as well as higer triglycerides are still here)..So should I stay low carb, keto for some time more or should I implement some safe starches/sweet potatoes to fully heal? Thank you in advance!

  18. Hi Chris

    My 10 year old daughter is having random bouts of low blood sugar levels. Would love to get your thoughts on this. When it gets really low (today was 36) she gets very sick. Low body temp, vomit once or twice, tired, stomach ache but hungry at the same time. Once it is high enough to eat, she eats a lot and starts getting strength back. We have been eating paleo/primal for the last two years. She does get starchy veggies and treats so she is not too low on carbs. Does this article apply to adults only? Do you have any research on children with blood sugar issues?
