Metabolism and thyroid health -
How fast or slow your metabolism works is determined partly by your genes. But a number of other factors play a role, including your age, gender, body size and composition, and your level of physical activity. Try these tips:. Take thyroid hormone. If you have hypothyroidism, which can be diagnosed with a blood test, your doctor will prescribe thyroid hormone therapy.
Rev up with exercise. Both cardiovascular and strength-training exercises are important for boosting metabolism. Strength-training exercises, such as weightlifting, build muscles, which help burn more calories.
Cardio exercises, including walking, jogging, biking, swimming, and aerobics , also help boost metabolism. Higher-intensity cardio exercise is more effective at improving metabolism than lower-intensity exercise, so try a more intense class at your gym or incorporate interval training into your exercise routine.
Avoid skipping meals and starvation diets. McAninch says. The signs and symptoms of starvation can also look a lot like hypothyroidism. Talk to your doctor or registered dietitian to develop a meal plan that works for you.
Choose protein. You should be eating throughout the day, but your food choices should be healthy ones that will keep your metabolism running strong.
That starts with including lean protein in your meals, says McAninch, and avoiding refined carbohydrates. Stay hydrated. While some research has found that water may increase the amount of energy you burn at rest by as much as 30 percent, another study found no connection between water and energy burned.
However, your body needs enough water to work well, and that means getting about 2. See your doctor before starting any supplements. There are no dietary supplements that can treat hypothyroidism in place of thyroid hormone, McAninch says.
And some supplements, such as those that contain iodine, can worsen hypothyroidism. Get enough shut-eye. It is not a substitute for professional medical care.

Metabolism and thyroid health Weight management tips count tthyroid times Metabolism and thyroid health have had a patient with weight gain come Thermogenesis and metabolic disorders my office certain thyrooid have thyroid disease. In this article, we will review what the thyroid gland is, healtj role Metabolism and thyroid health Metabolidm and what happens when it malfunctions. Your endocrine system is a group of glands in your body such as the pituitary, thyroid, pancreas, ovaries and testes that secrete hormones like growth hormone, thyroid hormone, insulin, estrogen and testosterone that regulate functions such as metabolism, growth, development and reproduction. The thyroid gland is the largest gland in the endocrine system. In your physical exam, when your doctor places a hand on the front of your neck and asks you to swallow, they are doing so to feel your thyroid gland. The thyroid gland produces three hormones: Thyroxine T4Triiodothyronine T3 and Calcitonin.Metabolism and thyroid health -
The variance in study results further illustrates how intricate the relationship between thyroid hormones and weight really is. The bottom line is that further research is needed. As discussed above, the simplistic explanation is that having an underactive thyroid often causes people to gain weight because their bodies stop using calories efficiently.
A lot of this weight is excess water and salt. Some studies have concluded that even mild hypothyroidism can lead to weight gain and changes in one's BMI. Once your hormone levels are within the normal range, you may lose a small amount of weight that mainly consists of the extra water and salt your body has built up.
One way to tell is if treatment has helped all of your other thyroid symptoms, but not your weight. You may have heard that thyroid hormones can be used to lose weight , even in people without thyroid disease.
While synthetic thyroid hormones have been used this way in the past, research has shown that most people gain all the weight back once they stop using them. Worse, being on thyroid hormones unnecessarily can result in serious side effects.
This is also an unhealthy way to lose weight, as an increased dose is also associated with adverse reactions, including heart issues, insomnia, headaches, menstrual irregularities, and skin rash. Many patients with an overactive thyroid end up losing weight. And in general, the more severe the hyperthyroidism, the more weight that is lost.
This usually reverses once your hyperthyroidism is treated. You may find that you gain back all the weight you lost, which is totally normal. If you eventually end up in a hypothyroid state, as many hyperthyroid patients do after thyroid surgery or radioactive iodine therapy, you may also run into the challenges of maintaining or losing weight.
In some cases, knowing how much to eat and discussing the best foods with a dietitian or nutrition professional can be a helpful first step. Lower T3 levels are associated with lower resting metabolic rates. As mentioned previously, when your metabolism is lower, you need both lower calorie intake and more activity to burn calories in order to maintain your current body weight or lose weight.
This can make losing weight extremely difficult. Another contributing factor to the weight loss challenge may be that hormone resistance problems often occur in people with thyroid disease, including leptin resistance and insulin resistance. Leptin Resistance. In the meantime, your thyroid slows down your metabolism as your appetite increases, you eat more, and you burn fewer and fewer calories, all resulting in weight gain.
And the more pounds you put on, the more leptin your fat cells make, further enabling this cycle. Insulin Resistance. Insulin is a hormone produced by your pancreas which keeps your blood sugar levels regulated. It works by telling your cells to absorb the excess sugar, or glucose, in your blood after you eat and to use it for energy.
As in leptin resistance, when your insulin levels are continually elevated, your cells become less sensitive to the signals insulin gives.
This results in needing even more insulin to keep your blood sugar level steady. Having higher levels of insulin causes weight gain and raises your risk of developing type 2 diabetes. Insulin is considered a fat-building hormone—it increases the amount of fat around the abdominal organs, which is highly inflammatory and can raise your risk of chronic diseases like type 2 diabetes.
Studies show that both hyperthyroidism and hypothyroidism can create insulin resistance. Thanks to the complexities involved with hormones and metabolism, the reality is that if you have an underactive thyroid, you may have to work harder to lose weight than someone without a thyroid disorder.
According to the American Thyroid Association, when your thyroid hormone levels are normalized, you should be able to lose, maintain, and gain weight just like someone without thyroid disease. It may also help to increase your protein intake, get your glucose and leptin levels checked, adhere to a healthier diet, and strengthen your muscles to boost your ability to lose those extra pounds.

Thyroid hormones and the metabolic syndrome. Eur Thyroid J. Try searching for: Metabolic health , Nutrition , Sports science etc. The thyroid is a part of the endocrine system and its intersection with the markers of metabolic health can reveal its pervasive effects.
It performs a vital role in regulating blood pressure, body temperature, heart rate, metabolism and the response of the body to other hormones.
It is responsible for producing key hormones that modulate metabolic rate, menstrual cycle, heart rate, breathing, muscle strength, body weight, and much more. The thyroid gland utilises iodine from the food to generate these hormones.
The thyroid gland makes the thyroid hormone by drawing iodine from the blood and integrating it into thyroid hormones. Thyroid cells are unique since they are highly specialized in absorbing and utilising iodine.
T3 and T4 meander in your bloodstream to reach almost every cell in the body. The thyroid-stimulating ho r mone is made and secreted into the bloodstream by the pituitary gland. Thyroid hormones help your body burn fat and provide you with more energy.
BMR is the number of calories your body needs to accomplish its most basic basal life-sustaining functions when it is at rest. A low level of thyroxine T4 and a high level of TSH stipulates an underactive thyroid.
When the TSH levels are high, it indicates an underactive thyroid, and the pituitary gland has to put in that much more effort to stimulate your thyroid. For your metabolic health to be at an optimal level, thyroxine needs to be broken down into triiodothyronine by organs like the liver and kidney.
Triiodothyronine is vital for many functions in our body such as muscle control, maintaining healthy bones, brain development, heart functions, metabolic activities and digestive functions. When thyroxine levels are low, it slows down crucial bodily functions that lead to health complications.
Hypothyroidism can slow down the heart rate and weaken the heartbeat. This puts a strain on your heart to efficiently pump blood to other organs, which is why one may feel shortness of breath while exercising. If hypothyroidism is left unchecked, it alters how nerves interpret information to and from the brain, giving rise to peripheral neuropathy, a result of damage to the nerves located outside of the brain and spinal cord, causing weakness, numbness and pain, usually in the hands and feet, and potentially affecting other areas and body functions including digestion, urination and circulation.
Metabolism is a series of chemical processes in each cell transforming the calories we eat into fuel to keep us alive. These processes sustain life, everyday functioning and include breaking down food and drink into energy and building or repairing our bodies. Metabolic health is described as having ideal levels of blood sugar, triglycerides, high-density lipoprotein HDL cholesterol, blood pressure, and waist circumference, without using medications.
Metabolic syndrome is a group of conditions that occur simultaneously, elevating your risk of heart disease, stroke and type 2 diabetes. These conditions include increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol or triglyceride levels.
A growing body of evidence points to the association between metabolic syndrome and endocrine disorders including thyroid dysfunction. Studies suggest that hypothyroidism is associated with factors of metabolic syndrome such as dyslipidemia, hypertension, obesity, and often insulin resistance.
Hypothyroidism also leads to increased levels of LDL cholesterol. All these factors are conducive to accelerated atherosclerosis, which is a disease marked by plaque build-up inside arteries.
The arteries stiffen and narrow, restricting blood flow and causing blood clots, heart attack or stroke. One of the telltale signs of hypothyroidism is a sudden onset of weight gain. Thyroid hormones, which circulate in your body as thyroxine T4 and triiodothyronine T3 , influence your metabolism through your fat cells, muscle, liver pancreas, hypothalamus.
When you have low thyroid hormone levels or minimal thyroid function, all of these functions can be disrupted. The body stores fat as a way to store calories, along with symptoms of low energy, which can be especially difficult to burn. Insufficient production of thyroid hormone is usually associated with a low basal metabolic rate.
Hence, hypothyroidism is responsible for weight gain. Thyroid hormones T3 and T4 strike a stellar balance of glucose homeostasis by functioning as insulin agonistic and antagonistic. Hypothyroidism can disrupt this equilibrium and alter glucose metabolism, which can lead to insulin resistance, a marker of impairment of metabolic health.
After eating, blood sugar levels rise. Insulin released by the pancreas helps the cells to absorb blood sugar for energy and storage. With this absorption, glucose levels in the bloodstream begin to decline.
The pancreas then produces glucagon, a hormone that prompts the liver to release stored sugar. This interaction of glucagon and blood sugar ensures stable blood glucose levels in the body and the brain. The glucose level in their blood rises over time even as their body produces more insulin as the cells resolutely resist insulin.
In such cases, the TSH fails to regulate and maintain the balance. Other causes include excess iodine in food, inflammation in thyroid, tumors, etc.
Some prominent telltale signs of hyperthyroidism are enlarged thyroid gland goitre , rapid weight loss, increased appetite, protruding eyes and high blood pressure.
With hyperthyroidism, your heartbeat increases. Irregular heartbeats increase the risk of being prone to a stroke. Excessive thyroxine in blood is known as thyrotoxicosis. This can strain the heart further. Thyrotoxicosis is also recognized by other signs like palpitations, tiredness, increased appetite, intolerance to heat, etc.
In order to measure your thyroid levels, a thyroid test depicting TSH, T3 and T4 levels is recommended. Thyroid plays an important role and should be optimised to avoid any health complications. A total T3 test quantifies the bound and free fractions of triiodothyronine.
T3 tests can be useful in diagnosing hyperthyroidism and seriousness of hyperthyroidism. Apart from measuring the thyroxine levels, T4 levels can also be affected by prescribed medicines that change thyroid hormone binding proteins. Hyperthyroidism causes impaired glucose tolerance, insulin resistance IR and insulin secretion.
However, the effect of thyroid dysfunction on glucose variability remains unclear. In hyperthyroidism your metabolism quickens, and insulin is metabolized faster.
Research indicates that the elevated plasma glucose levels in hyperthyroidism may be attributed to elevated rates of endogenous glucose production, due mainly to increased gluconeogenesis.
Gluconeogenesis is the process of synthesis of new glucose from noncarbohydrate precursors, providing glucose when dietary intake is insufficient or absent.
Gluconeogenesis takes place in the liver and kidneys. The antecedents of gluconeogenesis are lactate, glycerol, amino acids, and propionate making a minor contribution. The rates of insulin-stimulated glucose disposal in peripheral tissues in hyperthyroidism have been observed to be either normal or increased.
Skeletal muscle is the most important tissue for the disposal of glucose in response to insulin. Studies investigating insulin-stimulated glucose metabolism in skeletal muscle have suggested that, in the hyperthyroid state, it may be of primary relevance to spike the rates of glycolysis and lactate formation relative to glucose oxidation in this tissue in order to provide a substrate the substance on which an enzyme acts for gluconeogenesis increase Cori cycle activity.
The Cori cycle translates into the process of conveying lactate from cells that are undergoing anaerobic metabolism to the liver, where it is used to provide glucose back to the cells. This effect would be possible by a decrease in glycogen synthesis and an increase in glycogenolysis glycogen, the main carbohydrate stored in the liver and muscle cells is broken down into glucose to provide immediate energy and to maintain blood glucose levels during fasting.
When the severity of hyperthyroidism is amplified, an increased rate of glucose uptake into muscle may become essential, since the increased conversion of glycogen to lactate cannot be sustained for prolonged periods and might diminish glycogen stores.
This mechanism would ensure that the level of glucose in plasma is kept normal or slightly increased. Thus an increased Cori cycle activity may be important to create optimal conditions in hyperthyroidism for the control of glucose utilization without increasing the risk of hypoglycemia low blood sugar.
In addition to lactate, increased rates of gluconeogenesis in hyperthyroidism can also be sustained by increased plasma concentrations of amino acids mostly glutamine and alanine , glycerol, and free fatty acids.
The metabolism of individuals with hyperthyroidism works faster because of excessive thyroxine. Since their metabolism works harder and faster, they lose weight. They may also feel hungrier and gain weight in some cases. High basal metabolic weight is typically associated with excess thyroid hormone.
As a result, your body is burning more energy at rest, making weight loss a common symptom of hyperthyroidism. Thyroid hormones THs are primary determinants of cellular metabolism and modulate several pathways mired in the metabolism of carbohydrates, lipids and proteins in a number of target tissues.
Hyperthyroidism induces a hyper-metabolic state defined by increased resting energy expenditure, reduced cholesterol levels, increased lipolysis and gluconeogenesis followed by weight loss, while hypothyroidism causes a hypo-metabolic state marked by declined energy expenditure, elevated cholesterol levels, reduced lipolysis and gluconeogenesis and weight gain.

Your thyroid controls the chemical metabolic processes constantly taking place inside your body. This process of metabolism is how your body gets the energy it needs to survive and has a vital function. Your body needs iodine to make thyroid hormones. Most people get suitable amounts of iodine from their diet as it is found in most food, especially seafood.
