**keto diet for thyroid** Hypothyroidism is a medical condition in which the thyroid gland does not produce enough thyroid hormones. **hypothyroidism diet** can improve the symptoms of this disease. The ketogenic diet, or keto, is a low-carb, high-fat diet that has become very popular in recent years. In this article, we will examine whether the keto diet is beneficial for people with hypothyroidism. **Effect of keto diet on metabolism** The keto diet causes fundamental changes in the body's metabolism. In this diet, the body turns to using ketones (byproducts of fat burning) to provide energy due to the drastic reduction in the consumption of carbohydrates. This metabolic change can have effects on the function of various glands in the body, including the thyroid gland. **The effect of thyroid on metabolism** The thyroid gland plays a vital role in regulating the body's metabolism. Thyroid hormones (T3 and T4) have a direct effect on metabolic rate, body temperature, and energy levels. In hypothyroidism, the level of these hormones decreases, which can lead to symptoms such as fatigue, weight gain, and depression. Some studies have shown that low-carb diets can lower T3 hormone levels. T3 is the most active form of thyroid hormone, and low levels can contribute to symptoms of hypothyroidism. One of the reasons for this decrease is the decrease in insulin levels, which can lead to a decrease in the conversion of T4 to T3. **Advantages and disadvantages of the keto diet for people with hypothyroidism** According to Dr. Fanai, the thyroid gland needs carbohydrates and sugar to produce thyroid hormones. In this diet, the consumption of carbohydrates and sugar is minimized. As a result, when we stop consuming carbohydrates in this diet, the thyroid gland has trouble producing hormones. In general, the keto diet is harmful for hypothyroidism. People with hypothyroidism should be under the supervision of a doctor or nutritionist before starting any diet. After the necessary examinations by the doctor, it should be decided whether this diet is suitable for them or not. Below are some of the advantages and disadvantages of this diet: ### **General benefits of the ketogenic diet** #### **weight loss** Many people with hypothyroidism face the problem of gaining weight. The keto diet can help with weight loss, which may improve some symptoms of hypothyroidism and improve overall health. #### **blood sugar control** The keto diet can help control blood sugar, which is beneficial for people with type 2 diabetes and hypothyroidism. Better blood sugar control can improve energy and body function. #### **improving energy level** Some people have reported that their energy levels and concentration have improved with the keto diet. This may be due to a stable supply of energy from fats. ### **Disadvantages of the ketogenic diet for people with hypothyroidism** #### **Reduction of T3 level** Some studies have shown that low-carb diets can lower T3 hormone levels. T3 is the most active form of thyroid hormone, and low levels can contribute to symptoms of hypothyroidism, such as fatigue and weakness. #### **metabolic stress** Metabolic changes caused by the keto diet can stress the thyroid gland. This may worsen hypothyroidism or worsen symptoms. #### **Digestive problems** Some people may experience digestive problems such as constipation, nausea, and diarrhea. These problems may be due to sudden changes in diet and high consumption of fats. #### **Nutrient deficiency** Limiting the consumption of carbohydrates may lead to the deficiency of some vitamins and minerals. This can negatively affect thyroid function and overall health. #### **Inability to tolerate this diet in the long term** Some people may not be able to tolerate the keto diet for long due to severe dietary restrictions. This intolerance may lead to psychological problems such as stress and anxiety. ### **Modified ketogenic diet for hypothyroidism** A modified ketogenic diet for people with hypothyroidism can help with weight loss, blood sugar control, and overall health without harming thyroid function. However, constant monitoring and fine-tuning of the diet with the help of specialists is very necessary. Here are some tips for setting up a keto diet for hypothyroidism: #### **Increasing consumption of healthy carbohydrates** In the modified ketogenic diet, the intake of healthy, quality carbohydrates is gently increased to avoid a drastic drop in T3 hormone levels. Healthy sources of carbohydrates include: - Non-starchy vegetables (such as broccoli, spinach, and lettuce) - low sugar fruits (such as berries and avocado) - Nuts and seeds #### **Provide enough protein** Adequate protein intake is necessary to maintain muscle health and glandular function. Protein sources include: - Low-fat meats (such as chicken and turkey) - Fish and seafood - Eggs - Low-fat dairy products #### **Increasing consumption of healthy fats** Healthy fats should make up the majority of calories. These fats include: - Olive oil and coconut oil - Avocado - Nuts and seeds - Fatty fish (such as salmon and tuna) #### **Managing and reducing stress** Stress has a significant effect on the functioning of the thyroid gland. In stressful situations, the adrenal glands secrete cortisol, which is associated with increased levels of thyroid-stimulating hormone. Also, cortisol, along with stress hormones such as glucagon and adrenaline, work to increase blood sugar levels, which may prevent the body from entering a state of ketosis. #### **proper hydration** Drinking water has a significant effect on weight, energy, mental clarity and overall health. The goal is to drink about 8 glasses of water a day. Also, drink an extra glass of water if you drink coffee or alcohol, or if you've been sweating for 30 minutes. Of course, drinking fluids such as green tea and herbal teas also help to hydrate the body. #### **Avoid endocrine disrupting substances in agricultural products** Endocrine disruptors, or chemicals, may interfere with the body's hormonal systems, specifically affecting growth, reproduction, the nervous system, and the immune system. Therefore, avoiding agricultural products that are sprayed with chemical pesticides and herbicides can be appropriate to reduce their adverse effects on the body's hormonal balance. #### **Identifying irritating foods and avoiding inflammatory foods** Consuming irritating foods causes the possibility of increasing inflammation and intensifying autoimmune reactions or interfering with thyroid function. Therefore, avoiding inflammatory foods can help improve the thyroid condition. These materials include: - Refined sugars - Processed food Trans fats and saturated fats Some people may even react to eggs, soy, dairy, corn, shrimp, nuts and some additives. Therefore, it is always recommended that people with hypothyroidism be under the supervision of a doctor and follow a completely controlled diet. #### **Don't neglect the benefits of fasting** Fasting in a ketogenic diet may have many benefits and improve metabolism. Of course, it's best to check with your doctor before starting to see if fasting is safe for you. **Closing Remarks** With so many different diets out there for hypothyroidism and general health, choosing the best can be difficult. Keto diet for hypothyroidism can have advantages and disadvantages. Although weight loss and better blood sugar control can be helpful, lower T3 levels and metabolic stress may be problematic for some people. For this reason, before starting any new diet, people with hypothyroidism should consult a doctor or nutritionist to make sure that the chosen diet is suitable for their condition. Because each of us is unique and has our own sensitivities, and there is no nutritional method that is suitable for everyone.
