What is intermittent fasting?

Intermittent Fasting

Intermittent fasting in direct terms means time-restricted eating and fasting. Its meaning is easy— you restrict your eating window in a day between certain hours only. 

There are additional ways of fasting also like you don’t eat for the whole day or something called a water fast where a person just consumes water and no food. 

But intermittent fasting is contrasting with the above as in this method we are focused on eating daily but in a time-restricted manner. The most renowned way people do it is by keeping a window of 16 hours in a day where they don’t eat and the remaining 8 hours is the time when they will eat.

So for example, if you halt eating at 7 pm in the night and don’t eat till the next morning around 11 AM, this makes it 16 hours of a window where you have fasted. And then from 11 am to 7 pm is your time to eat.

Intermittent fasting for thyroid 

You are always concerned about slow metabolism which makes it difficult to lose weight. You feel depressed, and often have unsettling dreams akin to nightmares. And because the thyroid also regulates heart and muscle function, their health and overall functioning are impaired. Plus, when you research you come across warnings that fasting is bad for you if your blood sugar and Fat Storing Hormone levels aren’t optimal. Yours aren’t necessarily terrible, but still, the warnings scare you. Here let’s see what happens when you fast and what are the benefits for thyroid patients.  

So can intermittent fasting mess up your thyroid?

So, this conception came into being and it has been seen that longer fasting leads to lower thyroid hormone levels in the body.

This is an ancient study where people who were literally starving or were doing long fasts for days were included. This did depict that their thyroid hormone levels were slightly low, but they also reported that as soon as people started eating their thyroid hormone became normal again.

Now when your body gets into a long fasting state or starvation state thyroid hormone goes sparse because our body is trying to conserve energy.

Your thyroid hormone controls how much energy your body is going to burn. So by diminishing thyroid hormone levels, your body is trying to save itself from dying because of starvation.

Now intermittent fasting is different from this kind of fasting. As in intermittent fasting, we are fasting for a short time and not for days. So the body won’t get into starvation mode.

With this short fasting window, our body does get a lot of merits as this helps in better functioning of our body. This small fast helps our body to start burning the stores of fat and glucose in our body, and that, in turn, has several benefits like weight loss, mental clarity, and improving g energy levels.

Benefits of Intermittent Fasting for Thyroid 

Benefits Of Intermittent Fasting

  • Weight Loss-

    Major thyroid patients suffer from issues with weight gain. And even after trying multiple diets, they are not able to lose weight. But intermittent fasting can be beneficial for thyroid patients with weight issues. Our body processes energy from two food sources; one is carbohydrates and the other is fats. When we have a pool of food the excess glucose is converted to glycogen and fat and stored in the liver and muscles. Now when there is a shortage of food this glycogen and fat will be broken down to use for energy. Now in daily life, we eat almost every few hours in a day so we never have a scarcity of food so we never burn fat. Our body generally starts burning fat after about 8 to 12 hours of fasting but this can vary in different individuals. So in intermittent fasting, we transition our body’s metabolism to start burning the stored sugar and fats and thus can be helpful in losing weight. 

  • Reduces inflammation

    – We know that inflammation plays a vital role in causing thyroid disorders. Hashimoto’s is an autoimmune disease, which implies that inflammation is wrecking the thyroid gland. Also, intermittent fasting reduces insulin levels. It reduces inflammation by reducing levels of insulin.

  • Regulates Blood Pressure-

    Major thyroid patients are at risk of developing blood pressure issues or already have them. Intermittent fasting has shown phenomenal results in improving blood pressure. And this technique can help present and also treat blood pressure issues in thyroid patients. 

So, Intermittent fasting may raise the metabolism of your thyroid medications. It also swaps the way your body uses energy. If they are suffering from Hashimoto’s disease, well-timed intermittent fasting may improve inflammation and reduce the severity of this autoimmune condition. Also, Intermittent fasting, when done correctly, helps your body convert T4 to T3, just as selenium does. Because T3 is the active form of thyroid hormone, having more of it will improve your thyroid function if you’re hypothyroid.


Things to keep in mind
  • Not too processed foods and added sugars- Focus on nutrient-dense, whole foods like fruits, vegetables, beans, lean proteins, and healthy fats.
  • Eat foods rich in vitamins and minerals which are essential for thyroid function. Avoid soy products, and eat minimal cruciferous vegetables. Take adequate amounts of selenium, iodine, and vitamins A and D.
  • Let your body burn energy between meals- Don’t over-snack between meals and move your body throughout the day.
  • Consider a simple form of intermittent fasting- Choose the hours of the day between which you eat. For example, between 7 am, and 3 pm, or between 10 am to 6 pm. 
  • Eat breakfast to fuel your day-Eating breakfast is essential to fuel up for your day. Studies suggest that you attain a fasting state for a certain period each day. So, it is advisable to avoid late-night snacking or eating to give your body time to rest.
