Thyroid is a butterfly shaped gland at the base of neck. It produces two key hormones thyroxine ( also called T4) and triiodothyronine( also called T3).T4 accounts for more than 80% of the hormone produced by thyroid gland, If thyroid is running smoothly ,metabolism and mood will be too.But if gland doesn’t function properly weight loss and health goals get affected.
- An underactive thyroid gland hypothyroidism can cause symptoms such as weight gain, constipation ,tiredness,a feeling of being too cold, or frequent menstrual periods.
- An overactive thyroid gland can cause symptoms such as weight loss ,rapid heart rate, nervousness, a feeling of being too hot, or irregular menstrual periods.
However, the decrease in BMR due to hypothyroidism is usually much less dramatic than the marked increase seen in hyperthyroidism. Most of the extra weight gained in hypothyroid individuals is due to excess accumulation of salt and water.
Common roadblocks in the low thyroid function-
- High blood sugar-( high blood sugar and insulin resistance leads to thyroid dysfunction.
- Overweight or obese ( today’s western diet leads to continuous craving for processed carbs ,as a result we never feel full and we tend to overeat and with sedentary lifestyle ( leads to increase in visceral fat ,decrease thyroid gland function).
- Stress-Under stress, your body releases the hormone cortisol. Too much cortisol can interfere with thyroid hormone production. It can stimulate the thyroid to work harder to create sufficient amounts of thyroid hormone.
- Overtime by liver-A large amount of activation of thyroid gland (over 60%) happens in the liver and when liver is working overtime (due to too much drinking)than thyroid function is equally affected( A alcoholic drinking nightly,too much sugary and processed food consumption , coffee addiction all these possess a too much load on liver and ultimately make a person sluggish.
- Too much exercise-Sometimes doing the same exercise routine, body gets adapted to same training ,as a result person doesn’t losses any further weight,which creates stress and frustration in person which increase cortisol output that also impairs thyroid function. So it’s better to reduce training volume and increase the intensity.
- Iodine supplementation-The thyroid uses dietary iodine to produce thyroid hormone. Iodine is found in seaweed, fish and iodized salt. The thyroid gland is extremely sensitive to iodine, and a large amount of iodine in foods aggravate hyperthyroidism by promoting the gland to produce more thyroxine hormone and speed up metabolism further.
- Low selenium levels- Selenium is a mineral that acts like an antioxidant. Selenium-containing enzymes protect the thyroid under stressful conditions, while selenium-contains proteins that help to regulate hormone synthesis.
- Imbalanced gut-a condition in which large proteins like gluten (found in wheat, rye, and barley) and casein (found in dairy) pass through into the bloodstream and wreak havoc on the thyroid and cause inflammation throughout the body. Replacing these foods with gluten-free grains or going dairy free.
DIETARY HABITS TO TAKE CARE-
If you suffer from hypothyroidism, you might want to limit soy and cruciferous vegetables (broccoli, cauliflower, cabbage, and Brussels sprouts), as they can reduce production of thyroid hormone.
People with hypothyroidism may want to consider minimizing their intake of gluten a protein found in foods processed from wheat, barley, rye, and other grains,Gluten can irritate the small intestine and may hamper absorption of thyroid hormone replacement medication.
Amounts of dietary fiber from whole grains, vegetables, fruits, beans, and legumes that go above the required level affect your digestive system and can interfere with absorption of thyroid hormone replacement drugs.
Caffeine and alcohol has an effect on the thyroid gland and suppresses the ability of the body to use thyroid hormone.
Thyroid symptoms can be controlled by limiting the consumption of soy and soy-based products. The phytoestrogens present in soybean and soy-rich foods inhibit functions of thyroid hormone.
Sometimes clients with thyroid faces a weight loss issues it might be frustrating ,goal should be to discourage any food plan that creates a fear of food, sends mixed messages about what constitutes a healthy diet or is so restrictive that it leads to disordered behavior,frustration and stress.
