#23: What’s Your Body’s Thermostat Telling You?



Welcome back to the Be Fab – Be You Made Simple Podcast!

When it comes to thyroid, metabolism, and fat loss, there is so much to discuss. It’s estimated that approx. 20 million Americans suffer a thyroid disorder and up to 60% of them don’t know. This epidemic must stop.

I am starting today’s episode with the ending of episode #22 in mind. If you haven’t listened to it, I recommend you do so and today’s awesome content is more valuable to you. Also, this episode is loaded with sources. Check out the transcript to access them.

I ended the last episode with todays in mind. I touched upon a few thyroid hormones and mentioned that depending on your symptoms, you might consider doing a full thyroid panel. Insurance may or not cover the costs. Or if you don’t have insurance, you can pay out of pocket and I will glad to tell you what labs to run and if you are located in the US, I can tell you where to go to get them done as well.

I mentioned that there is ONE THING you can do right now, it costs little, you can do it from home, you don’t need a doctor, and it can be a better indicator of your health than lab tests, especially when it comes to your thyroid and metabolism.

And the answer is….


Measure Your Body Temperature!!!

It’s time to put that old fashion mercury or mercury-free glass thermometer to use. Put it in your mouth, let it sit there for 3-4 minutes. Then, take note.

Oral temperature offers a more accurate reading compared to underarm and forehead. Both are considered the least accurate.

If you don’t have a glass thermometer, Amazon is a few clicks away.

As I share this with you, childhood memories are popping up. Whenever mom felt I had a fever, she’d grab the thermometer, tell me to lay down, put in my mouth, tell me to be quiet, and return a few minutes later to check the temp.

The body operates within a narrow temperature range:

>> We are ok when the average temperature is between 98.4 F and 98.8 F.

>> Temperate of 99.0 F and you’re considered to have a slight fever.

>> Have your temp drop closer to 98.0 F and you WILL NOT feel at your best OR feel worse than whatever your baseline was already.

How is your temperature related to your thyroid and metabolism?

The thyroid controls the temperature in your body and it acts like a thermostat. When this precious gland isn’t working well, your body will feel colder.

If the average temperature of your body is equal to or less than 97.8 F or 36.5 C over a few days, your metabolism will be slow.


What’s the mechanism behind all this, you may ask! Great question…

Let me introduce you to ENZYMES!!!

You want to have a strong relationship with these guys and I will tell you next. Ready?

Enzymes are proteins that participate in changes and transformations of other substances. They are catalysts to chemical reactions and these reactions keep us ALIVE. No enzymes, no life! It’s thought that we have about 75,000 enzymes running the show inside us. They are divided into metabolic, digestive, and food enzymes.

Enzymes are involved in ALL of the body’s processes. Amylase and lipase are enzymes you may have heard about.

There are many things that inhibit and block enzymatic action and impact our daily health.

One of them is that enzymes are sensitive to temperature (high or low). Some of them depend on the body temperature of 98.6 F (or 37.0 C) or close enough to function properly. When your body is operating at or below 97.8 F (or 36.5 C), know that your metabolism is likely being affected.

When your body is colder because of thyroid dysfunction, your metabolism is interrupted. And the symptoms of obesity, depression, insomnia and others come a daily reality.

What about focusing on lab tests only for the thyroid?


Although the lab tests are good references, there are some issues with them. There is a thing called “sub-clinical hypothyroid”. That means the lab markers are indicating the hormones are within the normal range but the person is presenting the typical symptoms of hypothyroidism.

Many doctors rely solely on labs to assess the thyroid. For some reason, taking basal temperature isn’t scientific enough for them. They might be missing out on the obvious plus forgetting that the person’s feelings have a say here.


Remember that the thyroid sets the metabolic rate for EVERY CELL. Blood tests don’t pick up what’s going on inside the cell. The labs are showing what’s in the blood but not how the body is using them at the cellular level to produce energy. This energy level can be measured with body temperature.

Metabolism is movement. Movement uses energy to produce heat. More movement, more heat. Less movement, more coldness.  

Doesn’t this make sense?

Here is another thought for you…

Touch or hold a newborn and then touch or hug an older person. Warm versus cold, isn’t it?

The metabolism of a growing body of a baby is super high compared to that of an older individual whose life is ending. Plus, babies have a significant amount of brown fat, which helps to produce heat.

I know this might not be easy to hear but that’s reality and how the body works. There are many things we can from a lifestyle perspective to improve our metabolism and increase brown fat too, for that matter.  I am here to help you do just that.


It’s time for you to take action!

If you suspect you have a slow metabolism, check your temperature. That will give you the basis for seeking medical help or not.

If you do decide to take your basal temperature:

  1. Use glass mercury or mercury-free type of thermometer
  2. Do it orally versus armpit for better accuracy
  3. Measure it for 3 to 4 days
  4. Measure throughout the day, at least 3 times a day.
    1. Upon waking, without doing much at all, from your bed
    2. At least 1 hour after having eaten
    3. Before bedtime
  5. If you do 3 days and 3 measurements, you will have 9 measurements.
  6. Average your results and that will be your average body temp.
  7. If you average at or below 97.8 F (or 36.5 C), you may want to seek assistance.

I am not done talking about the thyroid and metabolism. A discussion about nutrients for your thyroid and metabolism is coming.
