Foods to Avoid if You Have Thyroid Problems (& Other Diet Tips)

Foods to Avoid if You Have Thyroid Problems (& Other Diet Tips)

I get it, you want to find a way to naturally heal your thyroid. And changing the food that you eat is probably one of the first things that you think about.

But does changing your diet actually help your thyroid?

Will consuming certain foods (while avoiding others) actually make you feel better?

The answer is probably not as straightforward as you think.

While consuming bad foods may cause harm to your body (and your thyroid), eating certain foods does not GUARANTEE optimal results.

Having said that, there are many things that are within your power that you can change, and that WILL help you feel better.

Let’s take a deep dive into those specifics to help you feel the best that you can:

Why Change Your Diet?

Instead of focusing on food as only a source of energy, it’s probably better to consider food as information for your body. 

If food is information, then this information can influence other systems in your body including neurotransmitters and even your hormones. 

The information (food) you put into your mouth can direct how much of specific hormones you can create and these hormones can impact other hormones and so on (1). 

And this is exactly what we see happen in real life:

For instance, if you consume high amounts of sugar, what happens to your body?

It secretes the hormone insulin which directs sugar into the cells in your body. 

food can impact genetic changes

If this continues to happen it can lead to insulin resistance and weight gain. 

Other information (foods) can influence the inflammatory pathways in your body. 

If you consume these foods then you run the risk of increased inflammation, disrupting gut microflora, and negatively impacting your thyroid. 

So why change your diet?

Because you can directly influence these systems in your body for better (or for worse!). 

My goal here today is to provide you with the right knowledge so that you can start to put the right information (food) into your body. 

As we jump into the specifics of foods that you should avoid it’s important to understand that simply avoiding these foods may not reverse your condition 100%. 

It will certainly HELP your condition but it may not be enough to reverse it completely. 

But, on the flip side, consuming large amounts of unhealthy foods will almost certainly cause long-term issues to both your hormones and your well-being. 

So, in this case, the benefits of changing your diet far outweigh any potential downsides (which is simply taking the time to understand how to change your diet). 

When changing your diet you will want to focus on foods that are nutrient-rich (meaning they provide your body with essential elements, nutrients, and vitamins) which help keep your cravings for unhealthy foods limited, which don’t cause metabolic problems (insulin resistance), and ones which make YOU feel good (gastrointestinal healthy, etc.) in the process.

These Foods Can Cause Problems For Your Thyroid

Before I just in here I feel the need to put out a disclaimer:

The information you are about to read is only generic advice based on what MOST people do or do not tolerate. 

While it may be very helpful for you to avoid these foods, there are certainly some people who can tolerate these foods to varying degrees!

For instance:

Most people (based on my experience) benefit from going dairy-free for a short period of time. 

A large number of people can re-introduce dairy afterward and do perfectly well on it at that point. 

While others simply cannot tolerate dairy even after an extended period of time (I fall into that category, unfortunately!). 

On several of the food groups below, I’ve put an asterisk (*) to indicate that this food group may be one with special conditions. 

I go into these food groups in detail in the advanced diet section which you can read more about later. 

With that in mind, let’s jump into the general list of foods that you probably want to avoid if you have thyroid disease:

#1. Sugar (Refined sugar)

why you should avoid sugar if you have thyroid problems

Sugar (in high amounts) can absolutely lead to hormone conditions such as insulin resistance and weight gain (2).

We also know that there is a bi-directional relationship between insulin resistance and thyroid disease. 

Beyond these hormone problems, sugar intake can lead to food cravings, depression, and other issues.

Does this mean you need to remove sugar from your diet forever?

No way! But it does mean that you should be extra strict in avoiding sugar if you haven’t for a long time. 

After a relatively short strict avoidance period, you may be able to add back some sugar into your diet depending on factors such as your activity level, body weight, and metabolism. 

After a while (the length of time varies based on your body) you may be able to introduce some natural sources of sugar such as maple syrup and honey without issue. 

#2. *Gluten (See below for more detail)

avoid gluten with thyroid problems for better gut health

While gluten is definitely a problem for a majority of people with thyroid problems, I am finding more and more that some people can tolerate gluten after a withdrawal period of 30-60 days.

Gluten is often mentioned as a ‘no-no’ if you have thyroid disease because Celiac disease is considered an autoimmune disease. 

This is a potential problem because we know that people with one autoimmune disease (such as Hashimoto’s thyroiditis) tend to experience other autoimmune conditions at a very high rate. 

And this connection appears to be true for people with Hashimoto’s thyroiditis who experience an increased risk of developing gluten intolerance by about 4x what is normal for the standard population (3). 

risk of developing celiac disease with thyroid disease

#3. *Dairy (See below for more detail)

dairy products can cause problems for thyroid patients

Many individuals in the United States are considered to be lactose intolerant (meaning they can’t handle the milk sugar lactose) while another group of patients are intolerant of dairy due to proteins such as casein.

You can figure out which group you fall into by avoiding dairy altogether for a set amount of time. 

But, regardless of why you don’t tolerate dairy, it’s not a good idea to consume it if you experience symptoms such as abdominal pain, gas, bloating, etc.

But another reason to potentially avoid it has to do with the fact that patients with thyroid disease (especially those with Hashimoto’s) may experience an improvement in their TSH when they avoid it. 

A study in 2014 showed that patients with Hashimoto’s who avoided dairy for 8 weeks experienced a reduction in their TSH (4). 

This was only true for those people with Hashimoto’s who also had lactose intolerance, but the researchers also found that people with thyroid disease tend to experience lactose intolerance at a higher rate than the normal population. 

The verdict? 

Consider removing dairy from your diet if you have thyroid disease and especially if you have Hashimoto’s thyroiditis!

The worst thing that can happen is that you experience no change in your symptoms while the best thing that could happen is that you feel a lot better. 

#4. Alcohol

alcohol is considered to be toxic to thyroid cells

It shouldn’t come as a surprise that alcohol can potentially cause problems to organs in your body (consider the case of alcoholic liver disease if you don’t believe me!).

It may surprise you to find out that alcohol also tends to cause problems directly with your thyroid gland. 

join 80,000 other thyroid patients who have used dr. westin childs' thyroid support supplements.

Alcohol has been shown to blunt your thyroid by inhibiting the release of pituitary and hypothalamic hormones (5) due to the fact that it is toxic to certain cells in your body.

Alcohol can also promote obesity through its influence on insulin resistance and it can ultimately lead to liver damage which can further impair thyroid function and conversion. 

If you have thyroid disease then you should avoid alcohol 100%. 

#5. Trans-Fat

trans fat causes problems for the entire body including the thyroid

Most people know that trans-fat is bad for your overall health but what you may not know is that trans-fat may also cause thyroid dysfunction.

Some studies have linked high-fat diets to thyroid dysfunction (6) – just another reason to avoid this type of fat. 

#6. Industrial Seed Oils & Fats

why seed oils can be harmful to your thyroid gland

It’s pretty straightforward but there are a number of oils that fall into the category known as partially hydrogenated vegetable oils (PHVO’s for short) and these fats have been known to cause inflammation in your body (7).

Inflammation is a problem for your thyroid because it blocks the conversion of T4 into T3.

This is one of the reasons that people recommend that you consume healthy fats (coconut oil, extra virgin olive oil, etc.) because these non-hydrogenated vegetable oils are not associated with inflammation. 

#7. *Highly Processed Soy

soy may cause problems for some people with thyroid problems

Soy is one of those foods that really fits in the middle ground of good and bad. 

What do I mean?

Some studies have shown that soy can theoretically cause problems in your thyroid such as blocking iodine uptake and potentially inhibiting thyroid medication absorption (8). 

The only problem is that these effects are not necessarily seen clinically in many people (9). 

So, on the basis that soy can theoretically cause thyroid dysfunction, it’s probably best to avoid it. 

There’s probably a big difference in the quality of the soy foods that you are consuming. 

If you find high-quality organic soy products (and you are an individual who can tolerate them) some mild use of soy is probably okay. 

But, if you are someone who tends to be very sensitive to foods or if your thyroid function is going hay-wire (with frequent fluctuations up and down) then you probably want to avoid soy altogether. 

#8. Frozen And Highly Processed Foods

highly processed foods like chips should be avoided for better thyroid health

Frozen foods and all-in-one meals all have one thing in common: plenty of preservatives. 

Preservatives help your food stay fresh for a long period of time which can be a good and bad thing. 

These preservatives are either man-made or naturally occurring but either way, they can potentially cause problems for your thyroid. 

What isn’t well known is how each of these preservatives (especially the man-made variety) impacts our health over the long term. 

And, because you just don’t need to consume a large amount of them (you can simply make fresh foods!) I recommend that you avoid them. 

You can find a list of how various known chemicals interact with and cause thyroid dysfunction in this study (10). 

#9. *Legumes/Beans

beans and legumes may cause gut problems for thyroid patients

It turns out that legumes and beans really don’t want humans to eat them. 

They have a combination of naturally occurring substances such as goitrogens and lectins (11) which can potentially cause problems for your thyroid. 

Proper preparation and handling of these foods can limit your exposure to these plant-based chemicals, but not everyone tolerates them the same (even after the correct preparation). 

Due to the fact that so many people simply don’t tolerate them, and due to the fact that these chemicals can potentially cause problems to your gut health, it is probably best to avoid legumes and beans at least initially. 

Re-introducing them at a later date will work well for some individuals, but you should not use them if you notice abdominal pain/gas/bloating afterward. 

#10. *Coffee

coffee can cause problems with thyroid function and thyroid medication

There are probably many of you out there who aren’t going to like this one, but you should at least hear me out! 

It’s not clear to me whether or not coffee is inherently good for you or bad for you because there are conflicting studies that show both sides to be true. 

But let’s table that discussion for today and focus solely on your thyroid. 

Coffee is potentially a problem for thyroid patients because it has been shown to temporarily suppress TSH (though this study was performed in rats). 

The suppression in TSH may not necessarily be a bad thing but in this case, it was because it was also associated with a decline in both T3 and T4 levels (triiodothyronine and thyroxine) about 6 hours after ingestion (12). 

This could probably be overlooked if it wasn’t the only problem. 

Perhaps even the biggest problem with coffee is the fact that it is primarily used (and perhaps abused) as a stimulant or energy supplement. 

The continual use of coffee to increase your energy may come at a cost to your hypothalamic-pituitary-thyroid and hypothalamic-pituitary-adrenal axes. 

Constant stimulation of these axes may diminish your normal hormone response to stress and cause issues such as fatigue, insomnia, and depression. 

Coffee is another one of those food groups that is probably well-tolerated by some people with varying degrees in the middle. 

Diets With Healthy Foods

I’m not going to go into the specifics of which type of food you should be consuming because that list would be incredibly long. 

Instead, I thought it would be better to provide you with a list of structured diets that contain that same list of healthy foods. 

These diets also have the advantage that they usually recommend that you avoid the list of negative foods we’ve already discussed. 

A win-win!

When it comes to your diet just remember that there is no one specific diet designed to meet all of the needs of your body and thyroid. 

Instead, several different types of diets fit this mold and they can strategically be used based on your existing medical conditions and health outcomes. 

For instance:

Some diets are better for weight loss while others are better at promoting gut health. 

You may need a combination of both so you can mix and match diets to fit your needs. 

If this seems confusing to you then you may benefit from a consult with a functional health coach (or doctor) to help guide you!

Without further ado, let’s talk about the structured diet plans that can be helpful for your thyroid: 

  • Paleo – The paleo diet is a great basic framework that most people are aware of. The benefits of using this diet are that there are plenty of free recipes available and a community to lean on for support. Some of the downsides of this diet include the fact that it can be restrictive, and expensive, and some recipes require obscure ingredients. 
  • Whole 30 – The Whole 30 diet is a whole-food-based program that is a great starting point for many people. There are plenty of recipes available online and a structured program to follow (including meal plans, shopping lists, and so on). 
  • Pegan Diet – The Pegan diet is a combination of the vegan diet and the paleo diet. It’s a diet that allows the inclusion of certain animal products and may be ideal for those who find either the paleo or vegan diet too restrictive. 
  • Autoimmune Paleo Diet (AIP) – The autoimmune paleo diet is a more strict form of the paleo diet. I do not frequently recommend this diet but it may be ideal for individuals with multiple autoimmune conditions. 
  • Gluten-free Diet – One downside to the gluten-free diet is that there are plenty of ways to make it unhealthy. Going gluten-free is probably best when accompanied by a healthy structured diet. 
  • Low Carb Diets – Low carbohydrate diets can be ideal for those with insulin resistance and those who are looking for weight loss. 
  • Ketogenic Diet – The ketogenic diet is a high-fat, moderate/low protein, and low carbohydrate plan. This diet is ideal for those looking for weight loss and for those who have certain medical conditions. 
  • Elimination Diet – The elimination diet is ideal for those who suffer from unexplained food intolerance-like symptoms and for those who don’t tolerate traditional structured diets. 
  • Low FODMAPS Diet – The Low FODMAPS diet (FODMAPS stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) is ideal for those with gastrointestinal problems such as IBS, non-celiac gluten sensitivity (NCGS), SIBO, and those suffering from chronic gas/bloating. 
  • Lectin Avoidance Diet – The lectin avoidance diet is a relatively new diet that focuses on the avoidance of foods that are high in lectins. Lectins can potentially cause problems in certain individuals (13) (not everyone is affected by lectins in the same way). These lectins are primarily found in healthy foods and may be the cause of persistent negative symptoms in some individuals who adopt healthy diets. 

As you can see, there are plenty of healthy diets which are available to those with thyroid disease and one is not necessarily better than the other!

My recommendation is to tailor your diet and the food you put into your mouth to your specific medical conditions and problems. 

Getting Enough Nutrients – Diet Vs. Supplements

Another primary reason that we consume food (outside of energy and information) is to provide our body with essential building blocks to maintain muscle mass, improve well-being, and allow cellular processes to function. 

These building blocks are obtained through the absorption of vitamins, minerals, and other essential compounds found WITHIN the food that you consume. 

In the past, the only way to really obtain these nutrients was through the use of food. 

But nowadays we have the added option of using supplements and vitamins to compensate for dietary deficiencies. 

Should we be using them, though?

The best way, hands down, to get your vitamins is from the food that you consume. 

An emerging problem, however, is that it can be difficult to get adequate vitamins and minerals despite eating a healthy diet. 


In order for your food to have vitamins and nutrients, the substrate must obtain those nutrients first from the ground or the soil. 

And we have seen that the soil which we use to grow crops has been depleted of certain nutrients. 

This means that while you may still be able to get SOME nutrients from your food, the concentration of certain vitamins and minerals may be lower than what we would have seen 50+ years ago.  

The combination of soil depletion of nutrients, unreasonable nutrient requirements of some people (due to absorption issues, certain medications blocking absorption, and the increase in demand due to exposure to endocrine disruptors, and so on) have led to a perfect storm. 

The storm of sub-optimal nutrient deficiencies that many people may face in spite of eating so-called ‘healthy’ diets. 

If you fit into this category (and many of us probably do), then the additional use of supplements may be required to help offset the reduced rates found in certain foods. 

And basic supplementation for general health is actually quite easy: 

Multi-vitamins contain both water-soluble and fat-soluble vitamins. The use of a multivitamin can help replete basic nutrient deficiencies and ensure that your body has what it needs. 

But the use of multivitamins may not sufficiently provide your thyroid with the nutrients that it needs. 

Instead, you may need to focus on more advanced thyroid supplements (those that help promote SPECIFIC functions) as needed. 

You can learn more about how I recommend that these supplements be used to target conditions such as low energy, weight gain, and more here

Gluten: Do you Need to Avoid it?

Gluten is a protein that gets a lot of attention in the general press and alternative healthcare industry. 

If you talk to most conventional doctors they will probably tell you that consuming gluten is perfectly fine as long as you don’t have Celiac disease. 

If you talk to doctors who are functional or integratively minded then they will probably tell you that gluten is the source of all of your health problems. 

Like most things in life, the truth is probably somewhere in the middle. 

Gluten can absolutely be a problem for people with thyroid disease (particularly for those who have Hashimoto’s disease) but it may not be an issue for everyone. 

In fact, newer studies have shown that going gluten-free may have a negative impact on your cholesterol, your risk of heart disease, your bank account, and your blood sugar (14). 

potential harm of avoiding gluten in your diet

On the other hand, this same study has shown that going gluten-free can be obviously beneficial if you suffer from IBS, NCGS, fibromyalgia, obesity, and certain mental health conditions. 

You’ll probably notice that thyroid disease wasn’t mentioned anywhere in that study so we will have to extrapolate some information and apply it to your situation. 

Instead of focusing on the rule that all thyroid patients should automatically go gluten-free, it’s probably better to take a more measured approach. 

Instead of focusing on your thyroid disease, you should focus on the myriad of other conditions that can also accompany thyroid disease and those for which going gluten-free may be beneficial for. 

If you find, for instance, that you have thyroid problems AND irritable bowel syndrome, then going gluten-free will probably be beneficial for your body. 

Going about it in this way will allow you to take advantage of the gluten-free diet without realizing the potentially negative health outcomes listed above. 

Goitrogens: Helpful or Harmful?

It’s also worth spending a quick minute explaining goitrogens and how they impact your thyroid. 

Goitrogens are compounds that inhibit thyroid function and block your thyroid from taking up iodine. 

Goitrogenic compounds include chemicals that naturally occur in food and exogenous chemicals that you can consume or come into contact with. 

The reason goitrogens come up in this conversation is that they are commonly found in healthy foods!

Foods that contain goitrogens include cruciferous vegetables (like kale, cabbage, and broccoli) as well as soy and beans. 

Does this mean that you need to avoid these healthy foods to protect your thyroid?

Not necessarily! (In fact, I don’t believe that to be true)

This is another one of those cases where the theoretical can get in the way of the practical. 

It’s theoretically possible that consuming large amounts of kale can inhibit thyroid function but this is just never really seen in real life. 

And, if you use this as an excuse to consume less-healthy foods then you are probably doing much more harm than good!

When it comes to choosing to consume kale over something like a donut or a pastry, then you should always opt for kale. 


The world of dietary advice can be confusing and I don’t envy people who are confused about all of the information available!

I’ve tried to make the information bite-size and easy to consume in this article. 

The bottom line if you have thyroid disease is this:

Try to find a structured diet (one with lots of online support and community) to follow and one that includes healthy foods that you should be eating while avoiding those foods that we know are potentially harmful to your thyroid. 

From there you can tailor or modify the diet to fit your specific needs. 

This will allow you to obtain the best possible results! 

Now I want to hear from you:

29 thoughts on “Foods to Avoid if You Have Thyroid Problems (& Other Diet Tips)”

  1. Ive been living with hashimotos for over 30 years now. Ive battled with pregnancies, depression,and weight issues, although I have managed to be a mother of 4 sons and a productive member of society.Until it seems, as soon as I hit my 60’s everything went belly up. Over the last 2 and a half years, my body has either been going haywire or shutting down.In short IBS issues were so bad full time work, then part time work was impossible,weight skyrocketed out of control. I began accumulating more autoimmune problems. At present after 18-20months on an elimination diet and then low fodmap the IBS is mostly controlled. But there are still many issues to be faced, the worst being unable to do more than 2-4hrs a day of anything like housework, sewing,driving,shopping. If this is exceeded I get fatigued, swell up in extremities, fall asleep at the wheel.If I continue to push myself, then IBS will reappear.I am unable to stay awake once the temp. goes over 25%C. Not only am I on a low FODMAP diet but I also have to avoid Gluten, Soy, Beans,Lactose, cane/refined sugar, anything with sulphur in it and preservatives of any kind.
    This leads to a very limited life, as of my 4-8hrs of being awake and functioning about 2hrs is taken up with preparing,cooking and eating. Ive got to the point of feeling like theres no use continuing if life is like this restrictive.

    • Hi Lynsey,

      I do worry about some diets which are too restrictive and which to lead to a poor quality of life. I believe that these types of diets will cause more harm than good long-term which is why I tend to not recommend them (except in rare cases). There’s always a way to improve your current situation, but it will involve working with a very knowledgeable dietician/provider/physician which is probably where I recommend that you start!

  2. Hello Dr. Childs, Thanks for a very informative article. I avoided gluten for about 10+ years but find now that I can tolerate some as long as the item is made of organic flour. I recently purchased your program and have been following the various recommendations in it with regards to diet, etc. I have also had a full battery of blood work done in the last couple of months which shows that I have Thyroid Resistance with a very low Free T3/Reverse T3 ratio however no insulin or leptin resistance or adrenal fatigue.

  3. Hello Dr. Childs, I have recently discovered through having the battery of blood work that you recommend that I have Thyroid Resistance with a 0.13 Free T3/RT3 ratio yet no indication of either insulin/leptin resistance or adrenal fatigue. I have had a lifetime of struggle with weight gain and suspect that this is something that has been going on undiagnosed for a long time. I am currently following your 60 day program and having success with losing weight which I am very thankful for. The main changes in my diet would be no dairy, grains, legumes or alcohol and a lot more fat. I am doing the prolonged fasting on the weekends and as well, 3 larger meals/day rather than 3 meals and 3 snacks as is often recommended.

  4. Dear Doctor Childs, thank you so much for all your information, I’ve learned from it very much. I’ve been on your Thyroid Supp, and take a lot of Nature-Throid (146), my thyroid had been removed 15 years ago. Despite high meds, my TSH is still 5.6, could you, please tell me, why, Janina.

    • Hi Janina,

      It’s probably dose-related or related to absorption issues. Either it isn’t getting into your body (absorption) or the dose isn’t high enough for your body.

  5. What would be a viable alternative to coffee consumption?
    How is it possibile to provide energy/stimulation without overtaxing the adrenals?
    How do I avoid withdrawl symptoms?
    Rebecca, a self-confessed coffee addict

    • Hi Rebecca,

      The best thing you can do is cut it out completely! You’ll withdrawal for a few days (Usually just headaches for 1-2 days) and then you’ll feel much better without it. From there you can only use it as necessary.

  6. Nice article but it misses two important factors that are fundamentally changing the “diseases of excess” model.

    The natural human diet: Whole food plant based.

    When you eat: fasting and intermittent fasting.

    I’d like to see the thyroid doctor crowd catch up with the latest in metabolic and longevity science and integrate these into their recommendations. Nothing has helped improve my Hashimoto symptoms more than these two.

  7. Hello Dr. Childs, I suffer with hypothyroidism and weight gain as also menopausal. I have previously had raw fruit/vegetable smoothies and eaten a balanced meal in the evening. I lost weight easily adopting this method and I felt good on it. However, I have read that raw spinach etc is bad for the thyroid. Can you tell me if this is true? Thank you in advance.

  8. I’ve have hashimotos for 37 years diagnosed, who knows before…I am gluten free because I get hives head to toe if I’m not. I also have been on the ketogenic way of eating for over a year and have lost 40 lb. I’d like to lose 10 more. I like keto because I am quite familiar with it and since I have to be GF anyway it is easier to stay focused. I am being treated for epstein barr virus and hopefully that will have a huge effect on my hashimotos which has gotten much more difficult since menopause.

    • Hi Jacqueline,

      Thanks for sharing! Treating EBV may definitely improve your Hashimoto’s but I’m not sure it will do much for your weight unless you also manage estrogen/progesterone/testosterone as all of these tend to fall after menopause.

  9. One can not reintroduce gluten after a 30-60 day avoidance because it takes at least 6 months for gluten to leave the system after one stops gluten. You post erroneous articles. Shame on you!

    • Hi Phoebe,

      Gluten is out of your system within a few days after you consume it (at most). Perhaps you are referring to the intestinal damage that it causes, assuming you are gluten intolerant? This might last months, but you certainly don’t need to wait 6 months to know if you are intolerant to it or not. The 30-60 day reintroduction period is just a way to determine if you should continue to avoid gluten or not.

  10. Hello. Recently diagnosed with no advice from my GP apart from the meds for hypothyroidism and reading up on here about supplements
    I asked my GP about kelp, zinc, magnesium. She said ok. The Chemist was reluctant to give me them and looked at a multivitamin but declined it as it contained iodine.
    I want to look after myself best I can. Also, I am looking into a partial meal replacement diet to see if I can shift some weigh. The weight seems to be mainly around my middle and my back. Thank you for your time

  11. Good day. Thank you so much for all your information. It has really been helpful. My biggest problem is when you search the internet, (which is where I found you, and I’m so grateful for that) you get tons of information about overactive thyroid and underactive thyroid, but very little to almost none about patients who have had their thyroid destroyed via the radiation treatment therapy. Which is my situation. So every time I read information and tips I keep asking myself if these apply to me because even though I now suffer from un underactive thyroid, its not because its naturally low, its because I don’t have a thyroid. Am I looking at these to deeply? Should I be reading and following all the information and tips of a underactive thyroid or is there a whole new lot of information and tips if you don’t have a thyroid?

    • Hi Michelle,

      The reason is that people who have had their thyroid destroyed/ablated/removed fall into the hypothyroid category. So anything you see on my blog related to low thyroid applies to you, as you mentioned above.

      There are some nuances that apply to your situation but 95+% of the low thyroid info applies and is relevant to you.

  12. Question: regarding coffee. What about decaf, organic, swill water processed? Or is it not the caffeine that is the issue?
    Hoshimotos for 20 years, hard to get functional doctor here in Houston. They removed everything except levothyroxin and only test TSH & T4 with a basic metobolic panel & CBC so I know supplementation and lifestyle are key for me.

  13. I am 66 and have been on Levothyroxine for 30 years due to hypothyroidism. Did very well up until about 4 years ago my basal temp is always low, I am cold all the time and T3 stays on the low normal side. Saw an alternative health care doc recently who tried to add bio identical T3 to my levothyroxine and I had heart palpitations, heart stress, insomnia and anxiety even with an extremely low dose after only 4 days on it. I read that the heart has receptors for the T3 which is why most docs won’t prescribe it. Have you ever heard of any successes adding T3? I walk 3-4 miles a day, weigh 118 pounds and eat a healthy diet. One of the reasons I initially consulted an endocrinologist 30 years ago was because I was cold all the time and had menstrual issues. Menopausal now but hate being cold all the time. Appreciate your thoughts.

  14. Hi
    I’m 68 and have been on 200 mcg of levothyroxine since 1994 – I am generally gluten and dairy free. My main concern is losing weight as I have had one knee replacement and can’t have the other one done unless I lose some weight -My T4 level is 16.9 ( range 7.0- 16.0)- too high and my TSH level is 0.006 ( range 0.38 -5.33) – too low and serum free triiodothyronine level ( Is this T3 ?) Is 6.5 ( range 3.8 -6.0) – high – so should I be on T3 ?

  15. I am conflicted with the dietary demands of hypothyroidism, to which I was diagnosed this year. I also have dry macular degeneration, which has no cure but blindness can be slowed down with the Mediterranean Diet & PreserVision Areds2–according to my opthalmologist. Add to that severe Arthritis. I’ve always consumed a fairly healthful diet with consumption of lots of fruits and veggies daily. I don’t have celiac disease, but I have bad reaction only to foods containing wheat. I eat a small bowl of fresh berries, one slice of GF bread (sometimes with one egg or veggie omelette or a slice of cheese) and a bowl of GF oatmeal with milk in it in the a.m.. I drink one cup of green tea with 1/2 tsp of honey for breakfast. I do not eat beans or peanuts due to gout flareups. However, I’ve been eating soy products (which seem like a no-no on your list of foods to avoid), like bean sprouts, tofu and edamame. I also have been cooking a lot of veggie stir-fry (w/ olive or coconut oil) with dash of GF Tamari soy sauce. I love vegetables and fish, except living in the desert makes it difficult to find fresh fish–only frozen. I usually have fish 2-3X a week, chicken 2-3X a week, and beef 1-2X a week. Given all of above, I still continue to gain weight along with all the other symptoms of hypothyroidism. In addition, I take Levothyroxine daily including your T3 Conversion Booster, plus daily vitamins of Magnesium, D3, and unfortunately Allegra, the only OTC pill I have to take to ease my chronic Urticaria. I’m wondering what more can I do to keep feeling the way I do, given all other ailments that I have to contend with daily.

    • Hi Marissa,

      Based on the information here, I would say that you should get a complete thyroid lab panel and assess your fat-storing hormones such as insulin and leptin. Even though diet is important both for thyroid function and weight management, it’s often not sufficient by itself to fix either. Getting your thyroid lab tests will tell you if you need to adjust your thyroid medication and whether or not you need more.
