Explore the Benefits and Risks of Intermittent Fasting While Taking Levothyroxine

Intermittent Fasting While Taking Levothyroxine

When it comes to managing your hypothyroidism, diet plays an important role. Intermittent fasting is one of the latest health trends and has been gaining in popularity. But is it safe for people with thyroid disease, such as those taking levothyroxine? In this article, we’ll explore the potential benefits and drawbacks of intermittent fasting while taking levothyroxine.

Overview of Intermittent Fasting

Intermittent fasting is an eating pattern that alternates between periods of eating and abstaining from food. It involves fasting for short periods of time, typically 16-24 hours. During the fasting period, no food or calorie-containing beverages are consumed.

Benefits of Intermittent Fasting While Taking Levothyroxine

Intermittent fasting can potentially help with hypothyroidism and does not present the typical problems of calorie-reduced diets. Research suggests that intermittent fasting may improve metabolism and reduce inflammation, both of which may be beneficial for people with hypothyroidism. Intermittent fasting may also help with weight loss, even with low thyroid levels. Additionally, some research suggests that intermittent fasting may improve the absorption of levothyroxine, the medication used to treat hypothyroidism.

Risks of Intermittent Fasting While Taking Levothyroxine

Although intermittent fasting may be beneficial for some people with hypothyroidism, it’s not suitable for everyone. Skipping meals or fasting for multiple days during the week may create nutrient deficiencies that can ultimately worsen a hypothyroid condition. Additionally, if you have the opposite problem with blood sugar that is too low, fasting can trigger inflammation and may actually flare your autoimmune thyroid condition.

Thyroid Hormone Replacement

Levothyroxine is the appropriate medication for thyroid replacement in both primary and secondary hypothyroidism. Levothyroxine is a synthetic form of thyroxine, the main hormone produced by the thyroid. It’s used to replace the missing hormone when the body is unable to produce enough on its own.

Patients who need levothyroxine replacement are advised to take it in a fasting state since it has been proved by many studies that optimal levothyroxine absorption is achieved when taken on an empty stomach.


Intermittent fasting can be safe for some people with thyroid disease, whereas others may experience adverse effects. It’s important to speak to your doctor before starting any new diet or exercise program, especially if you have a thyroid condition. Additionally, if you are taking levothyroxine, it’s important to take it on an empty stomach for optimal absorption.

If you decide to try intermittent fasting, it’s important to pay attention to your body and watch for any signs of feeling unwell. If you experience any adverse effects, it’s important to stop and speak to your doctor.

For those looking to improve their thyroid health, you may want to try adding Organic Icelandic Sea Kelp to your diet. This natural source of iodine may help to support thyroid health and can be purchased online.

In conclusion, intermittent fasting can potentially be beneficial for people with hypothyroidism, but it should be done with caution. Speak to your doctor before starting any new diet or exercise program, and be aware of any potential risks or adverse effects. Additionally, if you are taking levothyroxine, make sure to take it on an empty stomach for optimal absorption. Supplementing with Organic Icelandic Sea Kelp may also help to support thyroid health.

Is it possible to abstain from eating while taking levothyroxine?

Levothyroxine absorption is most effective when taken on an empty stomach; absorption is decreased to 60% when taken with food. This can lead to fluctuating and higher TSH levels in the blood.

Is it acceptable to consume thyroid medicine while fasting intermittently?

Yes, it is possible to fast while taking thyroid medication. However, it is not recommended as a healthy way to lose weight.

Is it safe for hypothyroid patients to practice intermittent fasting?

If you are diagnosed with hypothyroidism and want to lose weight, scientific evidence suggests that an intermittent fasting routine can be beneficial. Additionally, this type of fasting has been linked to decreased insulin resistance and improved overall health.

Will taking my thyroid medication interfere with my fast?

This is a discussion about Levothyroxine, a type of medicine. It is important to note that it has no calories and will not cause an insulin spike, meaning it is okay to take while fasting, as it will not break the fast and help absorb the thyroxine more effectively.
