For individuals managing hypothyroidism, dietary choices can play a pivotal role in improving health and alleviating symptoms. Doctors often recommend anti-inflammatory eating plans, such as the Mediterranean diet, which focus on nutrient-dense foods to reduce inflammation and enhance well-being. In contrast, the ketogenic diet (keto)—a high-fat, low-carbohydrate regimen popular for its weight-loss benefits—is generally not advised for people with hypothyroidism.

What is Hypothyroidism?

Hypothyroidism occurs when the thyroid gland fails to produce enough hormones to regulate metabolism and other essential functions. As a result, many people with this condition experience slowed metabolism, weight gain, or difficulty losing weight. While hormone replacement therapy remains the cornerstone of treatment, many individuals are curious about whether specific diets, like keto, could support their management plan or aid in weight loss.

The keto diet has gained significant attention for its potential to promote weight loss by restricting carbohydrates and utilizing fats for energy. A 2022 study published in the National Center for Biotechnology Information (NCBI) (source) suggested that individuals with thyroid disease might experience short-term weight loss on a keto diet. However, its long-term safety and efficacy for hypothyroidism remain unclear. Additionally, the diet’s potential risks, such as heart disease and digestive issues, are highlighted in StatPearls (source), making it a less favorable choice for those with this condition.

In this blog, we’ll explore why the keto diet may not be ideal for hypothyroidism. We’ll examine its effects on thyroid function, highlight alternatives like the Mediterranean diet, and provide actionable insights into eating patterns that better support thyroid health and overall well-being.

What Diets Are Best for Managing Hypothyroidism?

While there isn’t a specific “hypothyroidism diet,” certain eating patterns can significantly support thyroid health and help alleviate symptoms. Research, including a 2022 review (source), highlights the benefits of anti-inflammatory diets, such as the Mediterranean diet and plant-based eating plans, in improving thyroid health.

The Mediterranean Diet: A Thyroid-Friendly Choice

The Mediterranean diet is widely recommended for hypothyroidism due to its focus on nutrient-dense, antioxidant-rich foods. This eating pattern emphasizes:

• Vegetables and fruits

• Whole grains

• Legumes and nuts

• Healthy fats like olive oil

• Fatty fish rich in omega-3 fatty acids

These components help combat oxidative stress and reduce chronic inflammation, common in hypothyroidism and autoimmune thyroid conditions like Hashimoto’s thyroiditis. According to a study published in PubMed (source), the Mediterranean diet also provides essential micronutrients that support thyroid function, including:

• Vitamin A

• Vitamin B12

• Vitamin D3

• Iron

• Selenium

• Zinc

The Role of Gluten-Free Diets (GFD)

Although some studies suggest that a gluten-free diet (GFD) may reduce thyroid antibodies in autoimmune thyroid conditions, its benefits on thyroid hormone levels are less conclusive. For example:

• A 2019 study observed reduced thyroid antibodies in individuals with Hashimoto's on a GFD but found no significant impact on thyroid hormone levels.

• Some benefits attributed to GFD may stem from improved selenium and vitamin D intake rather than gluten elimination itself.

However, adopting a GFD without medical necessity, such as diagnosed celiac disease or gluten sensitivity, may lead to nutritional deficiencies, including reduced intake of vitamins B and D, calcium, and iron, and may increase dietary costs, making it less practical.

A Balanced, Holistic Approach to Diet

Rather than following restrictive diets, a balanced dietary approach is ideal for hypothyroidism management. Key recommendations include:

• Lean proteins (e.g., fish, eggs, poultry) to support muscle and hormone synthesis.

• Leafy greens and cruciferous vegetables (in moderation to manage goitrogens).

• Berries, nuts (especially Brazil nuts for selenium), and seeds for antioxidants and essential nutrients.

• Dairy products to ensure adequate iodine intake.

• Whole grains and seafood for selenium and other vital minerals.

Limiting highly processed, sugary, or inflammatory foods can further support metabolic health.

Personalized Nutrition for Better Results

Consulting a healthcare provider or dietitian is essential to tailor dietary choices to individual needs. Factors such as coexisting conditions (e.g., celiac disease) and nutrient deficiencies require personalized plans to ensure optimal thyroid health and overall well-being.

Are Plant-Based and Vegan Diets Recommended for Hypothyroidism?

Plant-based diets can play a supportive role in managing hypothyroidism, offering benefits such as reduced inflammation, improved weight management, and a lower risk of autoimmune thyroid conditions. While these diets may still include small amounts of meat, they emphasize plant-based foods like fruits, vegetables, whole grains, nuts, and seeds as dietary staples (source).

Research-Backed Benefits of Plant-Based Diets

A 2020 research review (source) found that people following vegan diets often experience:

• Reduced inflammation

• Better ability to maintain a healthy weight

• A lower risk of developing autoimmune thyroid diseases

Additionally, plant-forward eating—a flexible approach that includes plant-based foods alongside occasional meat, dairy, and eggs—has been associated with improved cholesterol levels, which is particularly important for managing high cholesterol linked to hypothyroidism (source).

Iodine Considerations for Plant-Based Eaters

Since iodine is a key nutrient for thyroid hormone production, plant-based diets must account for iodine intake to support thyroid health. While vegans and vegetarians can maintain normal thyroid function, regional soil iodine levels and dietary habits significantly influence iodine sufficiency. Key points include:

• Iodine sources:

• Iodized salt

• Certain legumes

• Fortified foods

• Moderate consumption of seaweed

• Overconsumption of iodine, especially through seaweed, can harm thyroid function and mimic deficiency symptoms.

Regular testing for iodine levels is recommended for plant-based individuals, particularly in iodine-deficient regions.

Cruciferous Vegetables and Soy: Are They Safe?

Cruciferous vegetables (e.g., broccoli, cauliflower, kale) and soy products contain goitrogens, compounds that may interfere with thyroid function if iodine intake is inadequate. However:

• Cooking these foods reduces their goitrogenic effects, making them safe for most people.

• When consumed as part of a balanced diet, these foods offer valuable nutrients and should not be avoided unless medically advised.

Holistic Benefits of Plant-Based Diets

Plant-based diets are rich in antioxidants, fiber, and phytonutrients, which not only support thyroid health but also reduce the risk of other autoimmune and inflammatory conditions, such as:

• Rheumatoid arthritis

• Crohn’s disease

Their anti-inflammatory profile promotes better metabolic and endocrine health, making these diets a holistic choice for managing hypothyroidism.

Public Health and Personalized Guidance

The potential of plant-based diets to mitigate thyroid disease risks highlights the need for balanced dietary strategies enriched with iodine. Personalized guidance from a dietitian or healthcare provider is essential to address regional iodine variability, dietary preferences, and specific health needs.
