l-Thyroxine monotherapy, the novel and physiologically savvy method for treatment of hypothyroidism, contrasted with the traditional approach of natural thyroid preparations that was marred by potency concerns. In less than a decade, there was a major shift in treatment of hypothyroidism such that normalization of TSH with l-thyroxine monotherapy became the new standard of care (Appendix Table) (52). Many clinicians advocated for this to be first-line therapy and for patients previously treated with desiccated thyroid to be transitioned to l-thyroxine monotherapy (50).
Although I’m a fan of getting what you need from real food whenever possible, herbs, supplements, and vitamins can still have a place in the thyroid diet plan. It’s hard to give tips here as many people over-medicate and only feel worse later. Hopefully these tips will help; they apply to most auto-immune conditions (This advice was given by my naturopath who focuses on hormonal and thyroid health.):
If your sex hormones (estrogen, progesterone, testosterone) and adrenal hormones (cortisol, DHEA) are out of balance, this can make weight loss more difficult. Perimenopause and menopause, as well as estrogen dominance, can also cause a shift of weight to the belly, and make weight loss more difficult. Lack of testosterone in men and women can also make it harder to build fat-burning muscle. And adrenal imbalances can make you tired, less responsive to thyroid treatment, and less able to lose weight.
Hyperthyroidism, particularly Graves’ disease, is known to cause bone loss, which is compounded by the vitamin D deficiency commonly found in people with hyperthyroidism. This bone mass can be regained with treatment for hyperthyroidism, and experts suggest that adequate bone-building nutrients, such as vitamin D, are particularly important during and after treatment.13
According to Dr. Datis Kharrazian, 90% of people with hypothyroidism have Hashimoto’s, an autoimmune hypothyroid condition, whereby the immune system attacks thyroid tissue. Therefore, to cure thyroid disease, or any autoimmune condition, you have to get to the source of the imbalance; focusing on suppression of symptoms with medication is simply barking up the wrong tree.
The thyroid controls how your body's cells use energy from food, a process called metabolism. Among other things, your metabolism affects your body’s temperature, your heartbeat, and how well you burn calories. If you don't have enough thyroid hormone, your body processes slow down. That means your body makes less energy, and your metabolism becomes sluggish.
Although relatively low serum T3 levels could contribute to these residual manifestations, the higher serum T4:T3 ratio should also be considered. This has been well-established for 4 decades (28, 50, 59), but only recently has it been recognized as a relevant measure given that higher serum T4 levels will impair systemic T3 production via downregulation of a deiodinase pathway (9). Thus, some emphasis has recently been directed toward establishing the clinical significance of this ratio (1, 5).
It’s imperative dietitians have a good understanding of the metabolic changes associated with thyroid disease so they can set realistic goals and expectations for clients. Most people with hypothyroidism tend to experience abnormal weight gain and difficulty losing weight until hormone levels stabilize. Moreover, it’s common for patients with Graves’ disease to experience periods of high and low thyroid hormone levels, so it may take several months to achieve a balance. During this time, it’s essential clients focus on healthful behaviors such as eating nutritious foods, exercising regularly, managing stress, and sleeping adequately rather than focus on the numbers on the scale.
There are also certain risk factors for hypothyroidism including radioactive iodine or anti-thyroid medications for hyperthyroidism, lithium, Congenital disease or tumors on your pituitary gland, pregnancy, miscarriage, premature delivery and/or preeclampsia, Iodine deficiency, autoimmune disease, enlarged thyroid glands or goiters, and high levels of low-density lipoprotein (LDL) cholesterol.
The thyroid gland uses iodine (mostly from foods in the diet like seafood, bread, and salt) to produce thyroid hormones. The two most important thyroid hormones are thyroxine (tetraiodothyronine or T4) and tri-iodothyronine (T3), which account for 99% and 1% of thyroid hormones present in the blood respectively. However, the hormone with the most biological activity is T3. Once released from the thyroid gland into the blood, a large amount of T4 is converted as needed into T3 - the active hormone that affects the metabolism of cells.
It's important to note, however, that selenium has what doctors call a "narrow therapeutic window." In optimal amounts, it can help ensure good thyroid function and have other benefits, but is toxic in amounts not that far above "normal." This is especially important to remember if you are taking a multi-vitamin that contains zinc as well as a zinc supplement.
Physicians hesitated to use l-thyroxine monotherapy over concern that it could result in a relative T3 deficiency, despite growing discontent with potency of natural thyroid products (39) and reduced cost of l-thyroxine, such that the 2 treatments were approximately equivalent (36, 41). The seminal discovery of peripheral T4-to-T3 conversion in athyreotic individuals largely obviated this concern (42). This laid the foundation for the corollary that treatment with l-thyroxine could replace thyroid hormone in such a way that the prohormone pool would be restored and the deiodinases would regulate the pool of active T3. Within a decade there was a major transition toward l-thyroxine monotherapy as first-line therapy (Appendix Table and Figure) (38).
Megan Casper, RDN, a dietitian based in New York City and the founder of Nourished Bite, points out that iodine deficiency is the leading cause of hypothyroidism worldwide. This mineral can’t be made by the body, so dietary sources like iodized salt, dairy products, seafood, seaweed, and fortified cereals are important. “Iodine is an essential nutrient in the body, and thyroid hormones are composed of iodine,” explains Rizzo. “Those lacking thyroid hormones may also be lacking iodine.”
