Optimizing Your Thyroid Health with Intermittent Fasting & Hashimoto’s

Intermittent Fasting Thyroid: How to Optimize Health and Manage Hashimoto’s

Intermittent fasting is a popular dieting trend, but it’s important to understand the implications of skipping meals or fasting for multiple days during the week, especially if you have a hypothyroid condition. Many people with hypothyroidism are insulin resistant, and when insulin resistance worsens, hypothyroidism can be exacerbated (10). While it’s true that intermittent fasting can reduce inflammation, it’s important to consider how it may affect your Hashimoto’s low thyroid.

When it comes to intermittent fasting and hypothyroidism, the scientific evidence is very clear: intermittent fasting can be beneficial in terms of weight loss and optimizing your thyroid health, but only if your blood sugar is stable and your adrenal glands are strong. If you are diagnosed with hypothyroidism and looking to lose weight, intermittent fasting could be a great option. Intermittent fasting can help your metabolism work more efficiently, as it shifts the way your body uses energy, and it can even help to raise the metabolism of your thyroid medications.

Intermittent Fasting and Hypothyroidism: Benefits and Risks

Intermittent fasting can provide numerous health benefits, even for people with hypothyroidism. It has been linked to improved cardiovascular health, reduced inflammation, and better glucose control, as well as weight loss.

However, it’s important to note that fasting can also be detrimental to those with hypothyroidism. When you don’t eat, your body will start to break down muscle tissue for energy, which can lead to a decrease in your metabolism. This can have a negative impact on your thyroid hormones, and it can also worsen symptoms of hypothyroidism, such as fatigue, depression, and constipation.

It’s also important to consider that fasting can lead to nutrient deficiencies, which can further worsen your hypothyroid condition. Nutrients like zinc, selenium, and iodine are all important for proper thyroid function, and if you are not getting these nutrients through your diet, you may be at risk for further health complications.

The Best Way to Intermittent Fast with Hypothyroidism

If you have hypothyroidism, it’s important to talk to your doctor before starting an intermittent fasting routine. Your doctor can help you determine the best approach for you, and determine if you need to make any dietary or medication adjustments.

If you are cleared to try intermittent fasting with hypothyroidism, it’s important to do so in a safe and healthy way. Start by fasting for shorter periods of time, such as 12-16 hours at a time. This will allow your body to gradually adjust to the new routine and give your thyroid time to adjust as well.

It’s also important to make sure you are eating the right foods during your eating windows. Eating a nutritious diet that is high in healthy fats, complex carbohydrates, and protein can help you maintain your energy levels and ensure that you are getting all the nutrients your body needs.


Intermittent fasting can be a great way to lose weight and optimize your health, even if you have hypothyroidism. However, it’s important to make sure you are doing it in a safe and healthy way. Talk to your doctor before starting any intermittent fasting routine, and make sure you are eating a nutritious diet during your eating windows. With the right approach, you can successfully manage your Hashimoto’s low thyroid and enjoy the many health benefits of intermittent fasting.

Does intermittent fasting have any benefits for the thyroid?

Intermittent fasting can potentially raise cortisol levels (stress hormones), which may have a detrimental effect on hormone-related issues such as PCOS and thyroid disorders. To minimize the risk, it is recommended that those with these conditions limit their fasting to no more than five days per week.

Does fasting on a regular basis have an influence on hypothyroidism?

There is no direct causal link between hypothyroidism and intermittent fasting. However, people with hypothyroidism could potentially benefit from intermittent fasting in various ways, such as aiding in weight loss, decreasing insulin resistance, and regulating immune responses.

What changes in thyroid hormones occur as a result of fasting?

Prolonged fasting can lead to a decrease in the amount of thyroid hormones (TH, T4, and T3) found in the blood and a lack of sensitivity in the hypothalamus-pituitary-thyroid (HPT) system (Boelen et al., 2011; Fliers et al., 2014).

Are thyroid issues capable of being temporary or recurring?

The levels of thyroid hormones in the body can change over the course of time, as a result of the progression of a thyroid condition. Additionally, age, hormonal changes, and variations in medication can all impact the levels of thyroid hormones, leading to a variety of symptoms.
