Not Losing Weight- Low Thyroid Might Be Why

Is your thyroid gland working against you? Is your low thyroid activity keeping you fat?

On this site, I’ve explored how poor gut health can lead to thyroid troubles—and eventually to weight gain. I’ve also discussed the connection between your thyroid and metabolism numerous times, including here

The reason I’ve written so extensively about underactive thyroid is because it’s such a common condition. So many people suspect it’s derailing their health; so many of them are right.

As someone who wants to provide you with the very best health tips, I feel it’s my responsibility to let you know how important thyroid health is, especially as it pertains to your weight.

What Does Low Thyroid Mean?

In case you’re not aware, your thyroid is one of your body’s main control centers—it’s essentially air-traffic control for your metabolism.

It produces T4 and T3, which are the main thyroid hormones, and T3 is the active form. It’s particularly important because it’s constantly in communication with your cells, regulating growth and cellular repair.

If you don’t have enough T3 getting inside your cells, then your body’s not getting crucial messages it needs to function correctly.

That’s bad… very bad.

Some people choose to supplement with thyroid hormone to boost their levels, but it’s not as simple as that. The conversion from T4 to T3 is something that happens in your liver and in your gut. That’s part of the process you need to mend if you’re suffering from low thyroid. Then there’s also whether or not T3 is getting inside your cells, if your brain is sending the right signals to your thyroid, and more!

That’s why simply taking more thyroid hormone (often just T4) is not going to help in many cases. 

What Causes Low Thyroid Function?

If you’re having a tough time losing weight, I would strongly suggest having your thyroid checked out. Your thyroid test results will give you crucial insight into the relationship between your thyroid and weight gain.

To help you with this, I have a really cool free thyroid blood test handbook. This will help you make sense of your thyroid test results so you can take appropriate action if needed.

With that said, you’re probably wondering how you get low thyroid in the first place.

The fact of the matter is that 90 percent of low thyroid is autoimmune; it’s something called Hashimoto’s disease, and it can be caused by the immune system attacking the thyroid.

Why does that happen?

Well, there are a lot of different reasons, from environmental toxins to the foods that we eat. Heavy metals such as lead and mercury have also been linked to low thyroid function, as has gluten.

In fact, gluten is a really big one. That’s because its protein structure closely resembles the thyroid tissue’s protein structure.

With repeated exposure, your immune system can confuse the two and, over time, start attacking your thyroid. Look for gluten substitutes wherever possible. You really don’t need it. I have a ton of great recipes on the site which will help you do away with it in your diet for good.

How to Lose Weight with Low Thyroid

To tackle low thyroid, you should also consider supplementation with two important minerals: iodine and selenium.

In the past it was said that we need to get a lot more iodine in our body, but the problem is that if we get a lot of iodine without the appropriate amount of selenium, that can actually increase the problem within the thyroid.

If you’re getting iodine from your diet, awesome.

If you’re supplementing with it, make sure that it’s balanced with the appropriate amount of selenium. I talk about this a little bit more in the free thyroid blood-test handbook.

If you’ve been eating a healthy diet and have been working out consistently but just aren’t shedding those pounds, strongly consider that low thyroid is probably at play.

It doesn’t happen overnight, but never lose hope because the human body is resilient; it’s always renewing itself. It regenerates new cells every single day, and it’s pretty amazing what can happen in the space of a couple months.

I hope this drills home the importance of the thyroid and why low thyroid is a condition that should be of utmost concern. If you have any doubts, get yours checked today!

Low Thyroid FAQ

What are low thyroid numbers?

There are a number of thyroid tests that can be done to get a better picture of what’s happening in your thyroid.
Generally, TSH levels lower than 0.3 mIU/L and free T3 levels lower than 2.0 ng/dL can indicate thyroid problems. For more blood tests and reference ranges be sure to download my Thyroid Blood Tests Handbook.

Why is low thyroid dangerous?

Low thyroid isn’t necessarily dangerous but it does slow your metabolism significantly since it’s your master metabolism gland.
Slow Metabolism - The Number One Cause
With low thyroid function you have trouble losing weight, have low energy, cold hands and feet, and even dry and brittle skin, hair, and nails—just to name a few problems that can arise.

How is low thyroid treated?

Low thyroid is typically treated, at least medically, with T4 medication like Synthroid. Sadly, low thyroid and hypothyroidism is more complex than just replacing one piece of the puzzle.
2 Natural Thyroid Treatments for Hypothyroidism
There are many parts in the thyroid “chain” that can be broken and therefore must be addressed. For instance, since T4 is converted to T3 (the active form of thyroid hormone) in the liver and gut, ensuring optimal health in both areas is crucial.
Also, 90% of hypothyroidism cases are autoimmune in nature (Hashimoto’s) which means that correcting the ultimate source of the problem (leaky gut) will be very important.
Additionally, you can support your thyroid with a good blend of nutrients like iodine, selenium, zinc, and N-Acetyl-L-Tyrosine.

How to test for low thyroid?

In addition the common blood tests for TSH, T4, T3, TPO, and reverse T3 you can also consider the following self-test for sub-clinical hypothyroidism—basically, low thyroid that won’t get picked up on a blood test:
Each morning, take your body’s temperature.
Normal body temperature at rest (taken in the morning) is between 97.8 F (36.56 C) and 98.2 F (36.78 C). Normal active temperature taken during the day should be 98.6 F (37 C).
If the average of the three daily readings—in the morning, over a period of 10 days—falls below 98.6 F (37 C) then you may suspect low thyroid function.

Which foods help low thyroid?

Going gluten free is very important since gluten protein mimics thyroid tissue and can lead to immune attacks against your thyroid.
Healthy Thyroid Tonic
Otherwise, eating a whole foods diet rich in plants is helpful. Seaweeds like kelp, nori, and dulse are good source of iodine and just one brazil nut per day will meet your selenium needs. Oh, and don’t be fooled by those who say cruciferous vegetables are bad for those with thyroid issues. Here’s the truth.

What supplements can I take for low thyroid?

Our ThyroThrive supplement has been specially formulated to support your thyroid with “super nutrients” required for proper thyroid function, which includes the right levels of L-tyrosine, iodine, and selenium. You can learn more about it here.
You may also want to consider a natural thyroid replacement therapy as bio-identical thyroid hormones. Nature-Throid is likely your best option as it’s a complete hormone (not fractionized like many pharmaceuticals.)
Please consult your doctor before moving forward.
