Thyroxine is a hormonal medicinal product which today everyone can get easily. Officially, it is released only with a prescription. Synthroid (levothyroxine) are often used not for their intended purpose. Most often, for the purpose of losing weight, less often – by athletes, during competitions or in preparation for them. One tablet contains 25, 50 or 100 micrograms of levothyroxine sodium. Also, the composition includes dextrin, microcrystalline cellulose, calcium hydrogen phosphate dihydrate.
Everyone knows that changing the hormonal background necessarily affects the mass of a person, so it is important to know how the thyroid affects weight. Given that the thyroid gland synthesizes and secretes into the blood hormones (triiodothyronine and thyroxine), which participate in almost all metabolic processes, the importance of this issue becomes more understandable. At a normal level of triiodothyronine (T3) and thyroxine (T4), which are also called thyroid, the body works like a clock, but with its violation, problems can arise in various systems of the human body – cardiovascular, gastrointestinal, central nervous system.
The thyroid gland located in the anterior part of the neck is a gland that produces a hormone that helps to control blood pressure, body temperature and weight. The thyroid gland is in the form of a butterfly. It affects many processes in our body. According to some estimates, women over 35 years of age are most susceptible to thyroid disorders. Compared with men, women have a 10-fold higher chance of getting sick. However, a significant proportion of people with thyroid gland dysfunction do not even turn to doctors for this problem.
The thyroid produces a special hormone, TH, which also regulates body temperature, metabolic rate and heart rate. Disturbances occur when the gland is little active or hyperactive. The causes of abnormal thyroid function include heredity, autoimmune disorders, pregnancy, stress, malnutrition, and harmful environmental agents. Because of the effect on many organs in our body, provided by the thyroid, doctors find it difficult to diagnose exactly its violations.
Due to the violation of metabolic processes with increased or decreased content of thyroid hormones and may appear overweight or its deficiency. Excess weight and the thyroid gland are connected by an indissoluble thread. From this article, you will learn how the functioning of the thyroid gland affects weight fluctuations. Many of us are ready to justify their overweight thyroid disease.
All diseases of the thyroid gland conventionally according to the level of work can be divided into 3 groups:
Let us remember what function the thyroid gland performs. It regulates the basic exchange. Its hormones accelerate all metabolic processes: the breakdown of fats, proteins and the assimilation of carbohydrates. Thyroid hormones are needed to get energy from any resources. And energy is needed for the work of all cells of the body. It’s like fuel for a locomotive.
The most important resource for humans in terms of energy is carbohydrates. If there is not enough carbohydrates in the consumed food, the fats begin to be consumed. This principle is based on most diets, where the main restriction is the ban on digestible carbohydrates. When the fats are already consumed from the fat stores, muscles are consumed.
With the confirmed hypothyroidism, it is possible to say that there is a connection between extra weight and thyroid dysfunction. In this case, actions against extra pounds should start with bringing the hormonal picture in the body to normal. Most often this implies the use of hormone replacement therapy, which consists in taking medications on the basis of an artificial thyroxine, in most cases it is L-thyroxine. It is regrettable, but in most cases such treatment is appointed permanently throughout the subsequent life, which, however, does not mean its inferiority. It should be remembered that the positive results of substitution therapy do not give the right to its independent cancellation, all decisions of this nature should be made by the attending physician.
For normal operation of the thyroid gland, the proper nutrition with a sufficient content of minerals, especially iodine, selenium, iron and zinc, is critical. Particular attention should be paid to the consumption of iodine and selenium, these minerals are often not enough in the diet of modern man. Iodine, which enters the body with food, the thyroid gland converts into hormones T2, T3 and T4. Rich sources of iodine are iodized salt and edible algae, and selenium is present in products of animal origin, seafood and milk. However, you won’t be able to solve the problem only keeping to a diet. It is more effective to combine Synthroid with the proper nutrition.
Thyroxine can be used to lose weight. It is not intended for this purpose, so in the instructions to the drug you will not find the recommended dose and frequency of admission for obesity. Usually levothyroxine for weight loss is used at a dose of 100 to 300 micrograms per day.
The higher the dose, the more likely the development of side effects. The most dangerous of them are from the cardiovascular system. Their probability can be reduced by the regular administration of β-blockers (atenolol, metoprolol).
Thyroxin provides weight loss due to the following mechanisms:
The effect of losing weight depends on the dosage of Synthroid:
In case of skipping the drug, it is not necessary to increase the number of tablets the next day. The duration of one course of L-thyroxine is 1-2 months. Abolition of the drug should be carried out smoothly, reducing the dose within a week. The break between the courses should be no less than 4 weeks. A month after the start of taking L-thyroxine recommended to pass a blood test for hormones TTG, T4 (free) and T3 (free). The results should show a slight hypothyroidism: TSH should be lowered, and T4 and T3 – increased. In the case of an increased heart rate, it is necessary to start taking antagonists (beta-blockers), which will help normalize the pulse and reduce the severity of other side effects.
Taking hormones and planning a diet, with hypothyroidism it is extremely important to follow the recommendations of physicians, as certain foods and vitamins can influence the ability of the body to metabolize drugs. For example, dietary supplements containing calcium and iron reduce the digestibility of hormones, so hormone-containing drugs are recommended in the morning, four hours before taking foods rich in calcium and iron.
Also, when hypothyroidism, it is not recommended to abuse products that block the thyroid peroxidase, the enzyme responsible for tyrosine and iodine connection with the subsequent formation of thyroid hormones. Such products include unfermented soy products, legumes and raw vegetables of the cruciferous family, such as broccoli, colored and Brussels sprouts. Heat treatment and fermentation reduce the content of substances that provoke goiter in these products.
Together with Synthroid, it is very important to observe the diet and the correct balance of calories. Each meal should contain 20-30 mg of quality protein. The protein saturates the body for a longer period than fats and carbohydrates, and also helps strengthen the tissues involved in the metabolic process. It is best to take the bulk of the daily dose of protein during breakfast, it is in the morning that our muscles need an increased intake of protein (exceptions are only a few hours after exercise). Not all sources of protein equally nourish and saturate muscles, for example, whey protein, a rich source of branched-chain amino acids (BCAA), is more effective in this respect than other sources of protein.
In the process of losing weight with dysfunction of the thyroid gland and Synthroid treatment is also very important to abandon the use of starch-containing carbohydrates. It is recommended to include in the diet of bread from sprouted whole grains, to replace pasta with sweet potatoes, and white rice to brown. It is very important to monitor the size of portions, if you are used to cooking two cups of rice, try to reduce the portion to one. As a snack, you can eat a banana, and if it’s really hard for you to give up the sweet, eat a peach.
Refined vegetable oils suppress the functions of the thyroid gland and provoke a set of excess weight. A pleasant exception in this case is coconut oil, which, on the contrary, normalizes the functioning of the thyroid gland, stimulates metabolism and prevents the collection of excess weight. Coconut oil can be added to food or simply eat with a spoon, starting with small portions and increasing the volume as the body becomes accustomed to the new product. The daily dose of coconut oil, recommended by nutritionists, is three and a half tablespoons. Do not necessarily at once eat the entire daily volume, divide it into several receptions during the day.
Hypothyroidism is not a reason to abandon the struggle for a beautiful figure. The main thing is to have patience, and adhere to an integrated approach to the problem of excess weight. Set goals and confidently go to their achievement and very soon you will notice the first positive results.
