There are many people who have tried every weight loss method out there with minimal or no weight loss results. If you are asking yourself “why can’t I lose weight?” and are unable to meet your weight loss goals after trying any and everything, your thyroid could be to blame. Thyroid problems are very common in the U.S. and the following is how your thyroid affects your metabolism which in turn determines your weight loss.
What is metabolism?
Everyone has a normal metabolic rate which varies from one person to another. Naturally thin people have a fast metabolism and those who are overweight usually have a slow metabolic rate. This rate is determined by a combination of various factors such as your genes, hormones, molecules, brain, gut, fat cell messenger chemicals, etc, all of which determine how many calories you shall burn a day (your metabolic rate).
The important thing to remember regardless of your rate of metabolism is that making a change to your diet and lifestyle, as well as adding exercise can significantly boost your metabolic rate which can cause you to burn more fat and lose weight. Exercise is probably the best way to naturally increase your metabolism.
If you are wondering “why can’t I lose weight?” as mentioned previously, hormones can affect your metabolic rate and the thyroid hormone can be a major part of this.
The thyroid hormone
The thyroid gland is the butterfly shaped gland located just below your Adam’s apple but just above your collarbone. It is from this gland that your thyroid hormones issue.
Thyroid hormones have several functions such as helping to control the amount of oxygen that each body cell in the body uses, your heart rate, the calories burned per day, growth levels, fertility, body temperature, mood, and so on and so forth.
It is the pituitary gland which creates the thyroid stimulating hormones which kick start your thyroid. Iodine that is present in your blood is then turned into thyroid hormones by the thyroid gland. The largest thyroid hormone produced is T4 a portion of which is converted into T3 which is the metabolism boosting thyroid hormone.
The amount of conversion of T4 into T3 if any, is dependent upon various factors such as stress, illness, diet components (both good and bad), environmental toxins that have found their way into your body, medication, aging, pregnancy, etc.
One way that your metabolism can be reduced leading to less calories being burned which can lead to weight gain, is when the amount of calories you eat per day are inadequate. This will cause the pituitary gland to reduce or stop producing thyroid stimulating hormones which leads to the thyroid producing less T4 hormones which then leads to less T3. Less T3 being produced leads to a slow metabolism and weight gain and the vicious cycle continues which means that you will be unable to meet your weight loss goals and grow increasingly frustrated.
Another factor related to the thyroid is that an under active thyroid (hypothyroidism) will lower your energy and you shall begin to gain weight because hypothyroidism slows your metabolism. The opposite problem – hyperthyroidism – represents an overactive thyroid which can lead to a racing heart, intolerance of warm temperatures, weight loss, fatigue, etc.
If you have tried various weight loss methods and been unable to notice any changes that has caused you to ask the question “why can’t I lose weight?” you may want to have your thyroid tested and if there are any problems, medication may be prescribed or other solutions recommended by your doctor to treat a problematic thyroid.
A properly functioning thyroid can help to boost your metabolism so that you can be able to lose weight and no longer ask the question “why can’t I lose weight?” There may also be other problems besides your thyroid that may be interfering with your weight loss.
