Action Steps: What Should You Do About Fasting

How I lost weight Intermittent Fasting with a Hypothyroid

In general, we have only seen some studies about intermittent fasting and time-restricted feeding. So, there may be more benefits that emerge over time with a larger sample of data.

That said, so far, these kinds of fasts have been on the detrimental side for those who are struggling with thyroid disease. To be blunt, it often does more harm than good.

On the other hand, it is important to know that a protein-sparing modified fast is safe for those with thyroid disease .

Key Insight: If you are thinking about fasting, but want to play it safe with your thyroid, you would likely be best suited to try a protein-sparing modified fast first.

Have Your Hormone Levels Tested

Research shows that hormone resistance problemsincluding leptin resistance and insulin resistancemay contribute to the difficulties many thyroid patients face in losing weight. And since both hyperthyroidism and hypothyroidism have been shown in multiple studies to create insulin resistance, this means you should consider having your fasting glucose and insulin levels tested, evaluated, and treated.

Fasting glucose levels above 100 may be a sign of insulin resistance and pre-diabetes, which can make weight loss even more difficult.

For chronically high levels, your doctor may prescribe a type 2 diabetes drug like Glucophage . For borderline levels, reducing the sugar and carbohydrates in your diet and following a healthy carbohydrate-controlled diet can lower your blood sugar and help with weight loss.

Intermittent Fasting With Hashimotos

I have worked with dozens of women with Hashimoto’s. Many of them come to my program believing that fasting is one of the worst things they can do for their thyroid health.

A Complete Guide to Intermittent Fasting and ...

There are a few things to consider when weighing if this style of eating is right for you. In looking at the research, here are the main takeaways for Hypothyroidism and intermittent fasting:

Intermittent Fasting may help with absorption of your thyroid medication

If you are taking synthetic thyroid hormone , fasting has some benefits. When taken during a fasted state, levothyroxine has been shown to be more efficient and absorbed better than those days when eating normally. The best time to take your thyroid medication is first thing in the morning, on an empty stomach. This is because there are various factors that may affect your thyroid medication absorption, but food is one of them and can greatly influence the absorption and efficacy. .

Intermittent Fasting may aid in weight loss, even with low thyroid

Intermittent fasting is another way to reduce the total calories you are eating. Reduction in total calories will generally lead to weight loss in a healthy person.

Nearly all Intermittent Fasting studies have resulted in some degree of weight loss, ranging from 2.59.9%. And while numerous studies have been conducted on intermittent fasting, the protocol, duration, and baseline characteristics of the sample population have varied greatly. It is important to consider the variation that a low thyroid condition can play.

My Experience With Intermittent Fasting

First off, what is intermittent fasting?

Intermittent fasting or intermittent energy restriction is an umbrella term for various meals timing schedules that cycle between a period of voluntary fasting and non-fasting over a defined period. Non-caloric drinks are consumable during fasting periods, contrary to religious fasting.

I first started implementing intermittent fasting into my diet back in mid-2016 when I was in a time in my life where I did a lot of experimenting in my diet.

Thats really all it was in the beginning, just an experiment that I would try out for six weeks only, or just about – but lets be honest, who really keeps track of the weeks as they pass?

After experimenting with intermittent fasting I remember going through brief bulking phase where I ate all the calories I could just to see how much muscle mass I could add on.

My bulking venture came to a screeching halt when I started having chronic inflammation issues from having too much dairy in my diet. Ill save this story for another time, but I literally started bleeding from my ears from having too much of an inflammatory diet .

So after I realized I needed to make some serious dietary changes, I naturally started gravitating back towards intermittent fasting.

I didnt plan it or strategize, I just fell back into it because it:

1.) was easy 2.) required less prep and thought than other diets, 3.) I wouldnt have to figure out what I was going to eat for breakfast everyday.

A Complete Guide To Intermittent Fasting And Hypothyroidism


Hypothyroidism is a condition in which your thyroid is underactive and does not produce sufficient levels of thyroid hormone. The result is that you cannot control your metabolism, heart rate, or body temperature adequately.

Common symptoms of the illness may include lethargy, depression, difficulty losing weight or sudden weight gain, sensitivity to cold, and constipation. Usually, older women get it.

It may be caused by Hashimotos disease, which is an autoimmune disorder that causes your immune cells to attack your healthy tissues.

Concerning the thyroid, this condition causes your immune cells to attack throat tissue, thus leading to thyroid inflammation.

Hashimotos disease often causes thyroid damage and a reduction in thyroid hormone levels.

Is Fasting Bad For Your Thyroid

Before we can talk about the physiological effects of thyroid and fasting, we need to define what we mean when we use the word fasting. There may be some misunderstanding around the definition of fasting and its subsidiaries, and it makes a big difference to understand the nuances between them when you look at and analyze studies.

Fasting = Traditionally No food at all. Oils, ketone supplements, etc. It includes water and may include black coffee and black tea. Anything that would break a fast such as carbohydrates, fats or proteins are not allowed. As simple as that.

Time-Restricted Eating = Time of food access is restricted but without caloric restriction. An example would be eating food within an 8-hour window during the day, but fasting for the remainder of the day, ie 16 hours.

Intermittent Fasting = Very similar to Time-Restricted Eating in that there is no eating for a prolonged period of time during the day, but usually restricts calories as well.

Now that weve cleared up what the differences are between these methods of fasting, we need to address some of the misinformation regarding fasting and thyroid function.

Figuring out how to fit fasting into your work, social, and health routine can be challenging, especially for those who keep unusual hours or lack routine. With any eating method, the goal should be consistency and overall health for the long haul.

For some, intermittent fasting may lead to new or trigger previous disordered eating behaviors.

What Is The Thyroid

The thyroid is a small butterfly-shaped gland located in the front neck. Itâs the master regulator of energy metabolism .

It does so with the help of hormones: Triiodothyronine , Thyroxine , and TSH . T3 and T4 are produced by the thyroid, TSH is produced by another organ: the pituitary gland.

These two organs regulate thyroid function by a neat interplay, which you can compare with a homeâs central heating system. The pituitary gland is the thermostat that is set to a certain temperature. The thermostat sends signals to the heater to turn on or off .

T4 is the major form and is long-lasting. It is converted into active T3, which is the hormone that affects cells and, thereby, regulates metabolism.

The pituitary gland measures the concentration of T4 in the blood. If T4 is too low, it secretes TSH. TSH then stimulates the thyroid to produce more T4.

If T4 is too high, the pituitary gland produces less TSH, and the thyroidâs T4 release goes down .

Why I Believed Strongly That Intermittent Fasting Has Positive Effects On Thyroid Functions

When your TSH level is drastically high , you can feel it even without a blood test. How? Waking up miserable every day, feeling super tired even you havent done anything yet, no appetite to work or do something and mood swaps.

In such cases, I bet you, if you would get your TSH levels checked, it would be 2 or 3 times higher than reference levels. This has proven by myself may be 10 times. So, it was me and my stubborn underactive thyroid gland that doesnt wants to get well. You can see my last visit for TSH test and here is the result. 11.25 mIU/mL.

If you are suffering from hypothyroidism, you probably heard about chronic inflammation which is the main factor to blame for such autoimmune diseases. Good news! Intermittent fasting has surprising corrective effects on chronic inflammation as well as Hashimotos Thyroiditis.

Even I have increased the Levothyroxine dose to 200 mcg, it was still helpless for me due to my miserable diet and lifestyle. So instead of increasing the dose, I have decided to change my life style with intermittent fasting and target chronic inflammation to decrease my TSH level, starting from 1st day of 2021. .
