    Eating a healthy diet can be difficult when you don’t have a functioning thyroid gland. Many people with hypothyroidism are left feeling exhausted and malnourished despite following mainstream dietary advice. Fortunately, there is a diet specifically designed for people without a thyroid—the hypothyroid diet—that can help restore energy levels and overall health.

    The hypothyroid diet focuses on eating nutrient-dense foods in order to support the body’s natural healing process. This includes eating an abundance of fresh fruits and vegetables, lean protein sources, healthy fats, complex carbohydrates, probiotics, and lots of water. Additionally, supplements containing iodine, selenium, zinc, vitamin A and B vitamins may be beneficial for those with a lack of thyroid function. By following these dietary guidelines and supplementing accordingly, it may be possible to restore energy levels – even without having a functioning thyroid.

    Overview of Thyroid Gland and Its Function

    The thyroid gland is a small, butterfly-shaped gland located in the front of the neck. It plays a key role in regulating many of the body’s functions, including metabolism, growth, and development. It does this by producing hormones, like thyroxine and triiodothyronine, that control the production of energy in cells.

    Understanding the function of the thyroid gland is important to understanding how to fuel the body when you do not have one.

    Anatomy of the Thyroid

    The thyroid gland is a small butterfly-shaped organ located at the front of your neck. It is responsible for producing and releasing two key hormones: triiodothyronine (T3) and thyroxine (T4). These hormones help to regulate many bodily processes.

    The hyperthyroidism can occur when the thyroid produces too much of these hormones, resulting in an imbalance. Conversely, hypothyroidism occurs when not enough of these hormones are produced by the thyroid.

    Another important aspect of your thyroid gland is its ability to store iodine from food sources such as grains, milk and eggs. Iodine plays a role in hormone production and helps to support healthy metabolism, growth and development. Your body uses iodine in many ways, so it’s very important that you get enough iodine in your diet or through supplementation if necessary.

    Thyroid Hormones

    The thyroid gland is responsible for the production of two hormones, thyroxine (T4) and triiodothyronine (T3). These hormones play a major role in regulating metabolism, which is the rate at which our body processes energy through the breakdown of fats, proteins and carbohydrates. Thyroid hormones also play an important role in how we manage stress, growth and development.

    When the thyroid isn’t producing enough hormones, hypothyroidism occurs. This condition can cause fatigue, weight gain and depression. Eating a balanced diet is especially important for those without a thyroid as it ensures that their body receives adequate nutrition to replace some of the lost metabolic functions caused by hypothyroidism. Eating nutrient-rich foods will help to reduce fatigue and boost energy levels. Foods that are rich in iodine are especially beneficial as this mineral helps stimulate production of T3 and T4 hormones.

    Impact of Thyroid Disease

    Having a thyroid condition can greatly impact one’s health and wellbeing, as it can cause a variety of symptoms ranging from fatigue to weight gain. For someone without a thyroid, it is important to be aware of the possible impacts of the disease in order to make the most appropriate dietary and lifestyle changes.

    In this article, we will discuss the impact of a thyroid disease on nutrition, and provide some tips for maintaining a healthy diet:

    Symptoms of Hypothyroidism

    Hypothyroidism is a condition caused by an underactive thyroid gland, which results in the release of too little thyroid hormones. Symptoms of hypothyroidism can vary but typically include fatigue, weight gain, cold intolerance, constipation, dry skin, and depression. Other more severe symptoms can arise if left untreated and can include goiter (enlargement of the neck due to an enlarged thyroid), heart palpitations and fertility issues.

    Best dietary practices for people with hypothyroidism include:

    • Eating nutrient-dense whole foods such as lean proteins, fruits, vegetables and whole grains. Nutrient-rich foods provide essential vitamins and minerals needed to support healthy functioning of the thyroid gland.
    • Avoiding processed/packaged foods with added sugar as sugar intake can prevent absorption of key nutrients needed for normal functioning of the thyroid gland.
    • Eating a balanced diet that includes a variety of foods from all food groups along with proper supplementation will help ensure proper function of the thyroid gland.

    Complications of Hypothyroidism

    Hypothyroidism, or an underactive thyroid, is a condition in which the thyroid gland does not produce enough of the hormones required for metabolism and overall health. It can lead to a variety of complications that range from mild discomfort to life-threatening issues. Hypothyroidism can cause weight gain, fatigue, dry skin and hair, sensitivity to cold temperatures, joint pain, high cholesterol and irregular menstrual cycles in women. It can also increase your risk of heart disease and certain neurological disorders.

    Treating hypothyroidism may require a combination of lifestyle changes such as diet modification and hormone replacement therapy. Eating a healthy diet low in animal fats and increasing intake of essential fatty acids like Omega-3s may help manage symptoms associated with hypothyroidism. Additionally, some studies suggest that supplementing one’s diet with iodine is beneficial for those suffering from this condition as it helps with hormone production in the thyroid gland. Ultimately, managing hypothyroidism requires individualized management with professional guidance from your doctor or naturopathic physician.

    Diet Recommendations for Those Without a Thyroid

    Nutrition is key for those without a thyroid, as the body is no longer able to take advantage of the hormones produced by the thyroid. A diet that is balanced, includes adequate calories and includes the right type of carbohydrates, fats and proteins is imperative. Eating foods high in micronutrients and antioxidants is also essential.

    Let’s explore the best diet for someone without a thyroid:

    Foods to Avoid

    People without a functioning thyroid should be mindful of their food choices to ensure they are getting enough nutrients to support health and avoid gastrointestinal issues. Foods that should be avoided when someone is without a functioning thyroid include:

    • Soy-based products
    • Cruciferous vegetables
    • Nuts & seeds
    • Spinach
    • Dairy products

    Soy may antagonize the action of the thyroid hormones and cruciferous vegetables can inhibit liver enzymes responsible for activating the hormones. Nuts & seeds contain compounds that can inhibit the uptake of iodine, which is essential for the production of thyroxine hormone. Spinach contains oxalates which may interfere with nutrient absorption and dairy may cause inflammation in those with hypothyroidism. Furthermore, as there are fewer enzymes responsible for regulating digestive processes when someone is without a functioning thyroid, it is important to limit processed and refined foods as they contain chemicals that can irritate or inflame the intestines.

    Foods to Include

    For thyroid patients without a functioning thyroid, it’s important to consume a diet rich in nutrients and vitamins that promote good health. To best support your body’s needs, opt for nutrient-dense foods like fruits and vegetables, lean proteins (such as fish and beans), healthy fats (like olive oil and nuts), whole grains, and dairy products. Additionally, be sure to stay hydrated by drinking plenty of water throughout the day.

    One issue with having an absent thyroid is the potential for nutrient deficiencies. As such, it might be beneficial to supplement your diet with foods that are high in iron—which can help the body produce red blood cells—as well as calcium and Vitamin D—which helps with bones health. Additionally, selenium supplements are especially important for those without a functioning thyroid because it helps with hormone production.


    Supplements are an important part of a diet for those without a thyroid, as they can help replace the hormones and nutrients your body may be missing. Consider taking iodine supplements if you do not have a thyroid, as it helps your body to regulate its metabolism. Selenium is also beneficial because this mineral helps to convert iodine into the required hormones for proper functioning.

    Other important supplements for people without a thyroid may include:

    • Vitamin D
    • Zinc
    • Omega-3 fatty acids
    • Probiotics

    Also consider taking digestive enzymes if difficulties with digestion or constipation occur. It’s best to consult with your doctor when considering taking any supplement or altering your diet in any way.


    When following a diet for someone without a thyroid, it is important to remember the main goal: to provide your body with the nutrients it needs to function properly and stay healthy.

    To do this, you should focus on eating nutrient-dense whole foods like fresh vegetables and fruits, lean proteins, beans and legumes, complex carbohydrates, healthy fats, probiotics and fermented foods. Additionally, it is important to minimize processed foods and added sugars as much as possible.

    Consult with a nutritionist or doctor if you have questions or concerns about any of the suggested guidelines or if you think it might be appropriate to try out certain supplements in order to help meet your nutritional needs.
