Together, the results suggest that T4, although less metabolically active than T3, reduces skeletal muscle efficiency and modestly increases resting metabolism even after short-term supplementation.
Does T4 make you lose weight?
Researchers found that higher baseline free triiodothyronine (T3) and free thyroxine (T4) levels predicted more weight loss among overweight and obese adults with normal thyroid function.
Does T4 affect metabolism?
T4 and T3 are what most people think of as “thyroid hormones.” These hormones play a significant role in your metabolism and in energy regulation in the body.
How does T3 and T4 affect metabolism?
Thyroid cells are the only cells in the body which can absorb iodine. These cells combine iodine and the amino acid tyrosine to make T3 and T4. T3 and T4 are then released into the blood stream and are transported throughout the body where they control metabolism (conversion of oxygen and calories to energy).
Can high T4 cause weight gain?
According to Dr. Kitahara, if someone has low thyroid function, their TSH is high, and the thyroid hormones known as T3 and T4 are low—and weight gain often occurs. If someone has an overactive thyroid or hyperthyroidism, TSH is usually low, the T3 and T4 are high, and weight loss occurs.
Can thyroid cause belly fat?
Even mild cases of hypothyroidism may increase the risk of weight gain and obesity. People with the condition often report having a puffy face as well as excess weight around the stomach or other areas of the body.
Why do I never lose weight?
There are some medical conditions that can drive weight gain and make it much harder to lose weight. These include hypothyroidism, polycystic ovarian syndrome (PCOS) and sleep apnea. Certain medications can also make weight loss harder, or even cause weight gain.
What does T4 do in the body?
T4 is a hormone that the thyroid gland produces. It regulates metabolism and plays a crucial role in digestion, muscle function, and bone health. T4 levels exist within a normal range. Hypothyroidism is where the thyroid produces too little thyroid hormone, which results in lower-than-normal T4 levels.
Does thyroid medication speed up metabolism?
One way to manage weight gain is by taking the thyroid hormone medicine your doctor prescribed. A daily dose of levothyroxine (Levothroid, Levoxyl, Synthroid) will rev up your thyroid hormone production again, and with it, your metabolism.

What regulates your metabolism?
The thyroid regulates your metabolism. The two main thyroid hormones are T3 and T4. Thyroid disorders are common, and they include goiters, hyperthyroidism, and hypothyroidism.
What is normal range for TSH and free T4?
TSH normal values are 0.5 to 5.0 mIU/L. Pregnancy, a history of thyroid cancer, history of pituitary gland disease, and older age are some situations when TSH is optimally maintained in different range as guided by an endocrinologist. FT4 normal values are 0.7 to 1.9ng/dL.
Can increasing levothyroxine cause weight loss?
One of the symptoms of an underactive thyroid gland is weight gain. So, once you start taking levothyroxine, you may lose weight as your body’s hormones rebalance. Losing weight can also be a sign that your dose of levothyroxine is too high.
What happens if T4 high?
A high level of T4 indicates an overactive thyroid (hyperthyroidism). Symptoms include anxiety, unplanned weight loss, tremors, and diarrhea. Most of the T4 in your body is bound to protein.
What are the symptoms of high T4 levels?
Symptoms of hyperthyroidism, also known as overactive thyroid, include:
- Weight loss.
- Tremors in the hands.
- Increased heart rate.
- Bulging of the eyes.
- Trouble sleeping.
What are the symptoms of high free T4?
If the thyroid gland produces too much T4 and T3, the affected person may experience symptoms associated with overactive thyroid (hyperthyroidism), such as rapid heart rate, anxiety, weight loss, difficulty sleeping, tremors in the hands, and puffiness around dry, irritated eyes and in some cases, bulging eyes.
