Unlock the Benefits of Intermittent Fasting for Thyroid Health: How to Manage Your Hypothyroid Condition

Thyroid and Intermittent Fasting: How It Can Help You Manage Your Condition

If you’ve been diagnosed with a hypothyroid condition, such as Hashimoto’s low thyroid, and you want to lose weight, intermittent fasting may be the way to go. Recent research has shown that, when done properly, intermittent fasting has the potential to improve your insulin resistance, reduce inflammation, and ultimately, help to manage your hypothyroid condition. In this article, we’ll explore the connection between your thyroid health and intermittent fasting and how doing it properly may benefit you.

What is Intermittent Fasting?

Intermittent fasting, or “IF” for short, is a dietary protocol that involves periods of fasting and eating. This usually involves fasting for 16-24 hours, and then eating within a 8-12 hour window. This is sometimes referred to as “time restricted eating” or “TRF”. It’s important to note that IF is not the same as long-term fasting, where you go without food for multiple days. With IF, you are still eating—just in a condensed window.

The Benefits of Intermittent Fasting for Thyroid Health

When it comes to managing your thyroid health, research has shown that there are a number of potential benefits to intermittent fasting. These include:

  • Reduced inflammation
  • Improved insulin resistance
  • Improved absorption of thyroid medications
  • Improved metabolism of thyroid hormones
  • Increased fat burning

These benefits can help to improve your overall thyroid health, and may even help to reduce symptoms and improve your condition.

Who Should Try Intermittent Fasting?

Intermittent fasting can be a great way to manage your hypothyroid condition, provided that your blood sugar is stable and your adrenal glands are functioning properly. Research has also shown that people with subclinical hypothyroidism may benefit from alternate day fasting as well. People who have a more serious thyroid condition, such as an autoimmune disease, should speak with their doctor before trying intermittent fasting.

Tips for Successful Intermittent Fasting

If you’re considering trying intermittent fasting for your thyroid health, there are a few tips that can help you to get the most out of it:

  • Eat nutrient-dense foods: Make sure to include plenty of healthy fats, proteins, and fiber in your diet.
  • Drink plenty of water: Staying hydrated is essential during intermittent fasting.
  • Avoid processed foods: Processed foods are often high in sugar and low in nutrients, and should be avoided during intermittent fasting.
  • Get plenty of rest: Your body needs rest to heal and function properly, so make sure to get enough sleep.
  • Be consistent: Consistency is key when it comes to intermittent fasting, so make sure to stick to a routine.

By following these tips and speaking with your doctor, you can ensure that you are doing intermittent fasting safely and effectively.


Intermittent fasting can be a great way to manage your hypothyroid condition, provided that it is done properly. It has the potential to improve your insulin resistance, reduce inflammation, and ultimately, help to manage your hypothyroid condition. However, it’s important to speak with your doctor before trying intermittent fasting, and to follow the tips outlined above for a successful and safe experience.

Could intermittent fasting lead to thyroid issues?

Intermittent fasting can lead to a decrease of up to 50 percent in the body’s active T3 hormone, which can potentially worsen hypothyroidism. Long-term dieting can also cause a similar decrease in T3 levels.

Is it possible for individuals with hypothyroidism to practice intermittent fasting?

If you are diagnosed with hypothyroidism and want to lose weight, research suggests that an intermittent fasting regimen may be beneficial. In addition to aiding weight loss, this type of diet can help improve insulin resistance and overall health.

How does fasting affect thyroid hormone levels?

Fasting for an extended period of time has been shown to cause a reduction in circulating thyroid hormones (TH, T4, and T3) and diminish the responsiveness of the hypothalamus-pituitary-thyroid (HPT) axis (Boelen et al., 2011; Fliers et al., 2014).

Which eating plan is the most effective for dropping pounds while dealing with thyroid issues?

Certain foods, such as those that contain goitrogens, can hinder the functioning of the thyroid gland and impede weight loss. Instead, it is recommended to focus on consuming items such as eggs, meat, fish, vegetables, gluten-free grains and seeds, certain varieties of dairy, and non-caffeinated drinks for better health.
