Hypothyroidism and Intermittent Fasting: What You Need to Know

If you have hypothyroidism or Hashimoto’s disease, you may have heard about the benefits of intermittent fasting. It is important to understand the potential benefits and risks associated with this dietary approach in order to make an informed decision about whether it is right for you.

Intermittent fasting is an eating pattern that alternates between periods of eating and fasting. It has been linked to numerous health benefits, such as weight loss, improved blood sugar control, and improved heart health, and it may also offer benefits for people with hypothyroidism and Hashimoto’s.

Pros and Cons of Intermittent Fasting for Hypothyroidism

Based on scientific evidence, an intermittent fasting routine can do you good if you are diagnosed with hypothyroidism and want to lose weight. Intermittent fasting may also help you manage your Hashimoto’s low thyroid. However, this depends on whether your blood sugar is stable and your adrenal health is strong.

If you have Hashimoto’s disease, well-timed intermittent fasting may improve inflammation and reduce the severity of this autoimmune condition. Intermittent fasting has also shown phenomenal results in improving blood pressure and can help present and also treat high blood pressure.

It is important to note, however, that intermittent fasting may not be for everyone. According to doctors, hypothyroid patients are best served by not fasting, which will exacerbate our already low thyroid hormone status. If we are already under-eating, intermittent fasting should be avoided.

Tips for Safely Following an Intermittent Fasting Routine

If you have been diagnosed with hypothyroidism or Hashimoto’s and want to try intermittent fasting, there are some important things to keep in mind:

  • It is important to talk to your doctor before starting any new dietary plan.
  • Make sure your blood sugar is stable before you start.
  • Listen to your body and look out for signs of fatigue or dizziness.
  • Drink plenty of water and stay hydrated.
  • Make sure you are getting enough essential nutrients and vitamins.
  • Ease into it gradually and take breaks if you need them.

Intermittent fasting is not recommended during pregnancy, for women who are breastfeeding, or for people with any type of eating disorder. It is also important to note that if you have hypothyroidism, you may need to take your thyroid medication at a different time of day when fasting, so it is best to speak with your doctor about this.


Intermittent fasting can be a powerful tool for those with hypothyroidism and Hashimoto’s disease, but it is important to understand the potential benefits and risks before starting any new dietary plan. If you are considering intermittent fasting, speak with your doctor and follow the tips outlined above to ensure that you stay safe and healthy.
