10 Best Hyperthyroid Diet And Exercise For Hyperthyroidism

A hyperthyroid diet and exercise plan can improve your symptoms of hyperthyroidism. A hyper-functioning thyroid needs medical management, but adding healthy food choices and an active lifestyle to that can result in better outcomes.

The thyroid is the butterfly-shaped gland located just below Adam’s apple in the neck. Hyperthyroidism is a disorder also known as an overactive thyroid. There are various causes of hyperthyroidism. One of the most common causes is Grave’s disease.

An overactive thyroid gland produces excess thyroid hormones – T3 and T4. These hormones are responsible for palpitations, weight loss, jitters, diarrhea, and excessive hunger and sweating.

Some foods and exercises help control these symptoms and have amazing effects on the overall well-being of hyperthyroid patients. Stick around to know the best diet and exercise tips we have in store for you.

Effects of Diet on Thyroid-gland

A healthy thyroid gland produces a normal level of T3 and T4. These hormones are required for the following functions:

  • Body metabolic rate regulation
  • Thermal regulation
  • Growth and development
  • Digestion
  • Heart functioning
  • Mineral homeostasis and bone density

The thyroid gland relies on specific nutrients and minerals for its functioning. Any imbalances caused by these nutrients and minerals can drastically affect the thyroid gland, leading to an overactive or underactive thyroid.

Hyperthyroid Diet and Exercise: 5 Best Foods

Foods low in iodine

Iodine is the building block of both thyroid hormones. Most of the iodine in our body is sourced from our diet, especially through iodized table salt. Lower the iodine intake means lower the production of thyroid hormones and lowers the symptoms of hyperthyroidism. 

Foods that are low in iodine include: 

  • Iodide-free salt
  • Egg whites
  • Fresh fruit (1 banana/day)
  • Fresh vegetables
  • Oatmeal
  • Unsalted peanut butter

Foods high in calcium and vitamin D

In a hyperthyroid state, excess thyroid hormones cause uncontrolled bone resorption and decreased bone mineral density. This can lead to osteoporosis and an increased risk of fractures.

Both calcium and vitamin D plays a vital role in bone formation and health. Vitamin D increases the absorption of calcium from the intestines. Dairy sources of calcium are usually avoided due to iodine content.

Non- dairy foods high in calcium and vitamin D include:

  • Broccoli
  • Kale
  • Fortified juices

Iron-rich foods

It is proven that iron deficiency impairs thyroid metabolism. So, here is a list of iron-containing foods to keep hyperthyroidism in check:

  • Green leafy vegetables
  • Dried fruits
  • Iron-fortified cereals
  • Liver – meat
  • Lentils

Foods high in protein and unsaturated fats

Hyperthyroidism is a state of a high metabolism that needs an ample supply of proteins and fats. This is to ensure there is no unnecessary breakdown of body mass, helping in weight management.

Foods high in protein and unsaturated fats include:

  • Lean meat – chicken
  • Freshwater fish
  • Beans
  • Legumes
  • Nuts

Selenium-rich foods

Studies have shown that deficiency of the element selenium can cause hyperthyroidism. So, including it in your diet can reduce the risk of worsening symptoms.

Foods that contain ample selenium include:

  • Chicken
  • Sunflower seeds
  • Brazil nuts
  • Brown rice

Goitrogenic foods

Some vegetables, nuts, and grains tend to act as goitrogens – substances that reduce the uptake of iodine and the production of thyroid hormones. These are beneficial in hyperthyroidism but are not recommended in hypothyroidism due to worsening of symptoms.

Goitrogenic cruciferous vegetables to include:

  • Kale
  • Radish
  • Turnip
  • Cabbage
  • Brussels sprouts
  • Broccoli
  • Cauliflower

Foods to Avoid in Hyperthyroidism

Although many vegetables and foods help manage hyperthyroidism, a few can worsen the symptoms and cause harm.

Avoid the following foods in hyperthyroidism:

  • Iodine-containing foods (Iodized salt, egg yolks, seafood, dairy products, etc.)
  • Caffeine-containing foods and beverages (chocolate, coffee)
  • Gluten-containing foods – celiac disease is a risk factor for Graves disease
  • Soy products – interferes with radioactive iodine uptake during treatment of hyperthyroidism

Effects of Exercise on Thyroid-gland

If you think the only diet will magically help you with hyperthyroidism, then I am sorry. Diet and exercise in hyperthyroidism go hand in hand. I know you’re already discouraged by the word ‘exercise.’

Hyperthyroid diet and exercise on a routine basis with all the hyperthyroid symptoms like anxiety, palpitations, and tremors is very challenging, agreed. But, at the same time, it is very satisfying. Although incorporating exercise into your schedule does not treat the root cause of hyperthyroidism, it surely can alleviate some of these symptoms.

CDC recommends 150 minutes of moderate physical activity per week for an adult. It works fine even if it is staggered into 30 minutes per day, 5 days a week. There are many options to obtain optimum physical activity gradually.

Before you start a new physical activity, it is essential to discuss your present condition, management options, and other factors with your physician and then proceed.

There are several forms of resistance training like:

  • Own body weight against gravity (Squats, lunges, planks, etc.)
  • Weight lifting
  • Resistance bands

Strength training

These are exercises that target your core body and aid in gaining muscle and bone mass. Some of these exercises may overlap with resistance training.

Strength training exercises include:

  • Squats

Yoga

Doing yoga every day is not only helpful for the body but also for the mind. Regardless of other exercise regimens followed, try to incorporate a few yoga asanas daily.

Here are a few poses that claim to be beneficial in hyperthyroidism:

  • Sarvangasana – Shoulder stand pose
  • Halasana – Plough pose
  • Matsyasana – Fish pose
  • Surya namaskar

Exercises to Avoid During Hyperthyroidism

Since hyperthyroidism can lead to severe consequences, any hyperthyroid diet and exercise that causes discomfort and aggravates you should avoid your symptoms.

Overexertion is highly discouraged. I know there are times we all feel invincible. Even if you think you have all the willpower in the world to keep going, it is best to draw a line when your body disagrees.

Always start your fitness regime with easy physical activities and then slowly ease into the moderate and advanced ones based on your comfort. If you are new to exercise, take time to learn the form before you injure yourself.

hyperthyroid diet and exercise

Some advanced level exercises to avoid for beginners include:

  • HIIT – High-intensity interval training – short bursts of high-intensity exercise alternating with a low-intensity exercise allowing recovery. This can cause severe fluctuations in heart rate, palpitations and worsen the symptoms of hyperthyroidism.
  • Advanced yoga postures – like the crane, crow, monkey and wheel poses, etc.-can result in accidents.
  • Heavy weight lifting – trying to lift weights beyond capability can cause severe injuries.
