A Comprehensive Guide to Intermittent Fasting and Hashimoto’s Disease

Intermittent Fasting and Hashimoto: A Comprehensive Guide

What is Hashimoto’s Disease?

Hashimoto’s disease is an autoimmune disorder that affects the thyroid, a gland that produces hormones essential for metabolism, energy, and other bodily functions. The disease is caused by the immune system mistakenly attacking the thyroid, leading to inflammation and potentially causing hypothyroidism. Symptoms include fatigue, weight gain, depression, dry skin, and constipation.

Can Intermittent Fasting Help With Hashimoto’s Disease?

Intermittent fasting has been shown to be beneficial for those with Hashimoto’s disease. As weight gain is a well known symptom of Hashimoto’s low thyroid, intermittent fasting in a stable metabolic state may help you lose weight. Additionally, intermittent fasting improves insulin resistance, which can be beneficial for those with hypothyroidism.

Fiber has a vital role in maintaining optimal gut health, which then indirectly affects your thyroid health. Skipping meals or fasting for extended periods can lead to nutrient deficiencies and an imbalance of bacteria in the digestive tract, which can worsen Hashimoto’s symptoms. Therefore, it is best to approach intermittent fasting with caution, especially if you have Hashimoto’s.

What Are the Benefits of Intermittent Fasting for Hashimoto’s?

Intermittent fasting can offer many benefits for those with Hashimoto’s. Studies have shown that it can reduce inflammation, which is a key factor in the development of Hashimoto’s. It also helps to regulate blood sugar levels, which is important for those with hypothyroidism. Additionally, intermittent fasting can help to regulate hormones, improve digestion, and increase energy levels.

How to Safely Practice Intermittent Fasting with Hashimoto’s

Doctors recommend that those with Hashimoto’s should not fast, as it can exacerbate their already low thyroid hormone status. If you choose to fast, it is best to do so in a stable metabolic state and to monitor your symptoms closely.

It is important to ensure you are getting enough nutrients when fasting. Eating nutrient-dense foods and supplementing with vitamins and minerals can help to ensure your body is getting the nutrition it needs.

You should also make sure to drink plenty of water while fasting. This helps to keep your body hydrated and can reduce the risk of dehydration. Additionally, it is important to avoid processed foods and sugar, as these can worsen Hashimoto’s symptoms.


Intermittent fasting can offer many benefits for those with Hashimoto’s. However, it is important to approach it with caution and to make sure you are getting enough nutrients. Eating a nutrient-dense diet, supplementing with vitamins and minerals, and drinking plenty of water can help you to safely practice intermittent fasting with Hashimoto’s.

Is it safe to practice periodic fasting with Hashimoto’s?

If you suffer from Hashimoto’s disease, it is worth discussing with your doctor the potential benefits of intermittent fasting, which may help reduce inflammation and improve the symptoms of this autoimmune condition. Intermittent fasting is not appropriate for everyone, and it should only be used as part of a weight loss or health plan if approved by a doctor or healthcare professional.

Is it possible for individuals with thyroid issues to engage in intermittent fasting?

Intermittent fasting can cause a rise in cortisol levels (stress hormones), which can have a detrimental effect in the short term on hormone-related issues. Therefore, individuals with PCOS or thyroid disorders should limit intermittent fasting to no more than five days per week.

Is it safe for people with hypothyroidism to practice intermittent fasting?

Intermittent fasting may be beneficial for those with hypothyroidism, but it is important to proceed cautiously. A good way to start is with a mild form of fasting, such as 12/12, and eating three meals each day.

Which diet would be most beneficial for a person with Hashimoto’s disease to help them lose weight?

The AIP diet is often recommended as a helpful way to support weight loss for those living with Hashimoto’s disease.
