Hypothyroidism and Insulin Resistance [4 Steps to Reverse it and Finally Lose Weight]

Do you feel like it's impossible to lose weight with Hypothyroidism?

​It actually isn't impossible and I will explain how later, but first I need to share a story with you. 

​I had a patient who came to see me in the office recently. 

She was 43, on levothyroxine (for years), about 60 pounds overweight, and wanted my help in balancing her hormones and help her lose some of that weight. ​

Like most other people, she had tried to lose weight following every diet you can think of, but nothing seemed to work for her. 

So I got to testing her labs.

Know what I found? ​

Elevated insulin with hypothyroidism

Insulin resistance. ​

And THAT was her primary problem.

Her thyroid wasn't all that bad, she ultimately did better on Armour thyroid - but her main problem was the insulin.

Once we got her on the right regimen, cleaned up her diet, fixed her adrenals, replaced nutrient deficiencies and put her on a fasting program her weight started to shed off.

And that's what we are going to talk about today.

​Hypothyroidism and Insulin Resistance. And why it's impossible to lose weight unless you address BOTH issues. 

What is Insulin Resistance?

​Insulin is the hormone that increases after you eat a lot of sugar. 

It puts sugar inside your cells and protects your body from high levels of sugar in the blood.

That's what it's supposed to do - when everything is working correctly.

When insulin levels remain chronically elevated (like when we eat a lot of sugar in our diet), your body becomes resistant to insulin. And that's where all the problems start.

High levels of insulin cause you to store the calories you eat from your diet as fat in your belly.

​So high levels of insulin = you gain weight (even if you eat fewer calories). 

I've put together a list of some symptoms I see in my patients that have insulin resistance: (But don't worry I will tell you how to order and treat your insulin resistance below)​

  • Inability to lose weight
  • Belly fat (or visceral abdominal fat)
  • Cravings for sugary foods
  • Irritability when going long periods of time without food
  • Dizziness and lightheadedness when fasting

Any of these symptoms sound familiar?

Let's talk about why insulin resistance is a big deal...​

Hypothyroidism is common but so is Insulin Resistance

If you count all of the people with Hypothyroidism you get pretty close to about 1 in 20 adults in the US. It's INCREDIBLY common.

Prevalence of hypothyrodism

​And on the other hand you have insulin resistance (AKA Diabetes) of which about 1 out of every 10 people have... 

Prevalence of diabetes and insulin resistance in the USA

​Not only are they both common, I find that most Hypothyroid patients are ALSO suffering from insulin resistance on top of their Hypothyroidism. 

And this can lead to weight loss resistance, inflammation and worsening hypothyroid symptoms. ​

Is Insulin Resistance Sabotaging your Weight Loss Efforts?

​Identifying and diagnosing insulin resistance is the first step to treatment. 

To understand why reversing insulin resistance is critical to weight loss we have to talk a little bit about physiology.

​We already mentioned that in the presence of insulin your body will store all calories you eat as fat. 

​But it also does something worse...

When insulin levels are high, your body is unable to burn your fat cells as a fuel source.

This process is mediated through a hormone known as hormone sensitive lipase.

So, in order to burn fat (and actually lose weight) you HAVE to reduce insulin levels.

To depict this I like to use this graph:

​(Photo credit: Peter Attia of Eating Academy) 

​As you can see: 

As insulin levels fall, your body is able to actually unlock your fat cells and start to burn them for energy.

When insulin levels are high, your body can't unlock your fat cells to use as energy.

That means your body uses primarily glucose as an energy source. Which can cause a lot of the symptoms I mentioned above...

As Glucose levels drop in the blood your body tells your brain to increase your cravings for sugary foods, it also makes you irritable, and sluggish.

Are any of these symptoms sounding familiar?

So how do you know if you have Insulin Resistance?

Diagnosing insulin resistance is actually pretty easy once you know what you are looking for.

The problem is that most Doctors will NOT be ordering these tests at baseline.

So, in order to get the proper evaluation, you may have to ask for and interpret your own tests.

Don't worry.

I can walk you through it. 

Ask your doctor for the following lab tests: ​

  • Fasting Insulin levels
  • Hemoglobin A1c (Abbreviate Hgb A1c)
  • Fasting blood sugar
  • You may ultimately need post meal glucose levels as well

Now that you have your lab tests in front of you, let's go over the "optimal" ranges:

  • Fasting Insulin levels: This should be < 5 (note that < 5 does NOT rule out insulin resistance) 
  • Hemoglobin A1c (Abbreviate Hgb A1c): Should be < 5.3 (note that Hgb A1c is not a perfect test by itself and a number of conditions can falsely elevate or decrease this value) 
  • Fasting blood sugar: Should be < 85
  • Post meal glucose: 2 hour post meal glucose should be < 120
Early signs of insulin resistance

​Believe it or not diagnosing insulin resistance can be very difficult, when in doubt I would recommend that you consult with your Doctor - just make sure you find one that is knowledgeable. 

*Resources and links for optimal ranges are at the end of this article. ​

Now that we know WHY insulin resistance is a problem, let's talk about how you can reverse it...​

​How to Reverse Insulin Resistance and Heal your Thyroid

Despite what conventional medicine would have you think, insulin resistance IS treatable. 

In the conventional medical world treatment is targeted at blood sugar. The problem with that method is that you are only going after the symptom of insulin resistance. 

Blood sugar rises as insulin resistance increases, and when it gets too high that's when Doctors diagnose you with Diabetes.

But diabetes is really just advanced insulin resistance.

And, while some medications can be helpful in reversing insulin resistance, the majority of your treatment should focus on the following areas:​

Diet to reduce Insulin levels

Diet i​s important in reversing insulin resistance, but alone it is usually not enough - especially for advanced insulin resistance. 

Increased insulin leads to obesity

​Consider the image above. 

What you put into your mouth can certainly cause increased level of insulin and ultimately lead to insulin resistance.

However, once insulin levels get high enough they can cause insulin resistance by themselves in a vicious cycle.

That's why diet is a good first step but usually not enough.

I recommend focusing on a nutrient dense, real whole-food diet, low in refined carbohydrates and sugar. You can get an exact idea of what I'm talking about by checking out my Thyroid Reset Diet here. ​

High intensity exercise routine

Everyone knows exercise is important, but the type of exercise matters a lot. Especially if you are trying to lose weight and reverse insulin resistance.

Studies show that High Intensity Interval Training is especially helpful in sensitizing your body to insulin.

​In addition, you can get more bang for your buck in a smaller amount of time. 

Not sure what High Intensity Interval Training (HIIT) is?

Let me explain:

​HIIT focuses on small bursts of all-out, maximum effort for about 30 seconds followed by 60-90 seconds of moderate activity. 

This process is repeated 5-8x in a single session at least once per week.

​This once per week activity is more beneficial to your body than doing an elliptical for 30 minutes and takes a much smaller amount of time. 

A word of warning for Hypothyroid patients:

Do not attempt high intensity interval training unless your thyroid hormone is optimized and your adrenals can handle the stress.

Exercise (of any kind) puts a physiologic strain on the body. It's the healing process, release of endorphins and cellular changes which cause all of the benefits of exercise.

And while exercise is important, it's better to take it easy at first otherwise you risk making your thyroid and adrenal function worse. ​

  • Quick Tip: If after exercising you are fatigued for several days then that is a sign you need to look at your thyroid and/or adrenal function. Exercising should make you tired and sore, but it shouldn't last more than 3 days. 

Intermittent fasting protocol

Fasting is a 4 letter word for a lot of people.

​But the truth is that fasting is probably the single most effective way to treat insulin resistance

​Here's how it works:

The longer you spend without eating the lower your insulin levels fall.

Once your body uses up the majority of stored glucose in the liver, your body MUST use triglycerides from your fat cells to provide your body with energy. 

As insulin levels fall your fat cells become "unlocked" by hormone sensitive lipase, and you are now burning fat for fuel and sensitizing your body to insulin in the process. 

This is obviously over simplified, but you get the point!

Fasting = good for reducing insulin resistance

​BUT, and this is a big but...

Like high intensity exercise, I don't recommend starting intermittent fasting unless your adrenals and thyroid function are optimized.

If you start fasting and you experience any of the following you may need to optimize your thyroid and adrenals first:

  • Dizziness or lighteadedness
  • Headache
  • Extreme cravings
  • Tremors or "shakes"
  • Intense thirst
  • Increased urination

​Do not attempt fasting if you are on insulin and a diabetic. You WILL need medical supervision and if you try to do it by yourself you may put yourself in danger from hypoglycemia. 

This is how I start patients on a gentle intermittent fasting program:

Start with 12-14 hours.

Eat an early dinner at 7pm.

Eat a late breakfast/early lunch at 11:00am the following morning.

Repeat this process twice per week. ​

Supplements to Treat Insulin Resistance

I saved this part for last, because it's typically the first thing people want to do!

While supplements can definitely help reverse insulin resistance and help you lose weight, they should NEVER be used in isolation.

If all you do is grab your supplements and go, you will not experience the results you are looking for.

Having said that these are the supplements I recommend to my patients which have scientific studies backing them:

  • Berberine - I recommend using 1,000mg at least daily. Berberine has been shown to be as effective as Metformin in reducing Hgb A1c
  • Pure Lean PurePack - This has a combination of Cinnamon, Alpha lipoic acid, Chromium and Green tea - all of which have been shown to decrease insulin resistance. I use this because it puts everything in a nice convenient to use package and includes other helpful nutrients that most people are deficient in. 
  • Konjac root - This supplement is a viscous fiber that expands in your stomach helping to keep you full, feed good gut bacteria and reduce insulin resistance. It's also been shown to actually help with weight loss. For maximum benefit take 4 capsules 15 minutes before each meal and while intermittent fasting throughout the day. 

We are going to put this all together at the end for maximum effect, so keep reading. 

Do you have debilitating fatigue?

When trying to add these tips into your regimen it's VERY important that you don't do more harm than good. 

Before you start doing high intensity interval training or intermittent fasting you need to make sure that your thyroid hormone medication is optimized and that your adrenals can handle the stress. 

If you aren't sure whether or not you should start I would recommend you check out this post here.

If you are still having hypothyroid symptoms, or the signs and symptoms of adrenal fatigue I would caution against exercising and fasting.

​Also take note that there is a difference between brain based fatigue and physical fatigue. 

In brain based fatigue you will get fatigued after heavy thinking or mental activity. If you are experiencing this type of fatigue then exercise CAN help. 

In physical fatigue you will be wiped out after exerting yourself physically. If you are experiencing this type of fatigue then exercising and fasting may make your condition worse. 

Medications that help sensitize your body to insulin​

In addition to supplements there are some medications that can actually help sensitize your body to insulin.

Most of the time this won't be an issue if early insulin resistance, but if you have diabetes (and advanced insulin resistance) you may be on 1 or more medications.

If you fall into this category I would recommend you optimize your medications and consider getting on one or more of the following:

​Other medications may actually cause an increase in insulin (especially if they stimulate the release of insulin). 

See your doctor for further information. ​

Here's what you need to do now​

​You won't start feeling better and losing weight unless you take ACTION. 

With that in mind I've come up with 4 steps that I want you to follow to get the process moving:​

  • Change your diet: You have all of the resources here to make it happen in my Thyroid Reset Guide. My guide has all the guidelines including what foods to eat, what foods to avoid and what portion sizes you need. 
  • Balance and check your hormone levels: Insulin resistance is made worse by other hormonal imbalances like increased levels of leptin. You can find out what hormones I'm talking about here and how to go about getting the right tests. 
  • Get your supplements and start using them: These are the supplements that I recommend and use in my clinic - Berberine, Purelean Pure Pack, Konjac root
  • Consider adding intermittent fasting and HIIT into your regimen (advanced): Use caution when adding these into your routine. I recommend starting with the other options above first. 

Now I want to hear from you
