The Thyroid Gland And Its Function
The Thyroid gland is a tiny organ that is located in the front of the neck, right below the Adams Apple. The function of the thyroid gland is to take incoming iodine and other nutrients from foods and convert it into thyroid hormones. These hormones are responsible for many different functions within the body including the regulation of your metabolism.
The Thyroid Disorder Is Associated More With Unhealthy Choices Than Genetics
When it becomes difficult to burn fat even when sufficient amount of exercise is present, many of us give up on our diets and fitness goals. However, this might be partly due to the low thyroid function that is causing the inability to burn fat. With some people the thyroid dysfunction is genetic. For others, a low thyroid function is due through years of unhealthy choices they made and their livelihood.
The Thyroid Gland Dysfunction – Warning Signs
The thyroid is often the first organ in the body to be effected by negative outside influences. Usually, the first signs of a thyroid dysfunction happens after you reach your mid twenties. Some warning signs include fatigue and an increase in weight. Some people will try to lose this weight and realize that the fat will not burn off as fast as it once did when they were younger. More often then not, this fat loss effort is halted by frustration and ends with previous unhealthy habits returning.
Over time, chronic low thyroid function is reached. Also called hypothyroid. This condition has a very damaging impact on the body’s ability to burn fat. There are drugs to help this condition. But these medical drugs prescribed for hypothyroid only mask the true problem of the thyroid abnormalities.
In order to truly deal with the thyroid dysfunctions, one must understand the purpose of thyroid and the hormones it produces.
The Thyroid Production Of Hormones
Hormones are released from the thyroid into the body based on info it gets from the brain. This is a complex process that involves various nutritional factors. There are three different thyroid hormones that are released into the blood. They are…
- Thyroxine (T4)
- Triiodothyronine (T3)
- Reverse Triiodothyronine T3 (rT3).
Thyroxine (T4) is the major hormone secreted by the thyroid gland. T4 controls the metabolic rate and influences physical development. This prohormone is a reservoir for the active thyroid hormone Triiodothyronine (T3), which is much more potent.
Triiodothyronine (T3) affects many different processes within the body including…
- Heart Rate.
Reverse Triiodothyronine (rT3) does not stimulate thyroid receptors but they do bind to them. Because rT3′s are not active, when they bind to the thyroid receptors, they block T3′s from doing their job. rT3′s are made when the body is under stress. This stress causes the body to produce a hormone called cortisol. Cortisol inhibits the conversion of T4 to T3, causing the production of rT3.
What This Means For Fat Burning
If there are too many rT3′s present around the receptors, then the T3′s will not be able to dock into the cell and the body will never get the thyroid message to burn fat as fuel.
There are a lot of different factors that effect the body’s ability to create, release, and deliver the thyroid hormones to the cell receptors. Some of these factors involve human physiology. While other factors come from our environment.
3 Important Nutrients Responsible For The Thyroid Hormones
There are a lot of nutrients needed to make thyroid hormones. But the more important ones include…
The vitamins and minerals one requires has to be consumed daily through your diet. Unfortunately, the average diet is inferior and is deficient in the 3 nutrients listed above.
Food Allergies And The Thyroid Function
Food allergies can be very frustrating concerning thyroid disorders. Most food allergies are very slight and will not get an immediate reaction (i.e. eating a peanut). The type of reaction from a food allergy that affects the thyroid could disrupt its function up to 4 days.
Two of the most popular food allergic reactions comes from dairy and wheat. If your diet is good and you are exercising consistently and still not losing fat, try to remove these two foods from your diet. They may be disrupting the function of your thyroid and just might do the trick to restoring normality to your thyroid function.
The Thyroid Response On A Low Calorie Diet
Thyroid efficiency is a big problem for those trying to lose fat on a low calorie diet. By drastically reducing your calories, the thyroid slows down. Less thyroid hormones are released. Most of the hormones that are released gets converted into rT3 on a low calorie diet. This means your fat burning metabolism slows down dramatically. Basically, a low calorie diet sends the body into hibernation mode. The thyroid tells the body to stop burning fat as fuel because less calories are being consumed. This is your body’s natural survival process during a dramatic decrease in calories consumption.
Restoring The Thyroid – Summary
- Provide the thyroid gland with all nutritional factors required to create thyroid hormones.
- Reduce negative environmental factors. (Mercury, Allergic foods, Pesticides, Toxins).
- Avoid extreme low calorie diets (incorporate interval training cadio and weight training).
Although fat loss is not guaranteed, you will have a way better chance of fat loss when restoring the thyroid to normal operations.
