The thyroid gland, located in the neck, produces hormones—primarily thyroxine (T4) and triiodothyronine (T3).
Thyroid hormones regulate the metabolic rate, determining how efficiently the body burns calories. An underactive thyroid (hypothyroidism) can lead to a slowed metabolism, making it more challenging to lose or maintain weight
Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormones
Hyperthyroidism is a condition where the thyroid gland is overactive, leading to an excess production of thyroid hormones
Thyroid hormones influence the distribution of fat and muscle in the body. Changes in thyroid function can affect body composition, leading to alterations in weight and the distribution of fat.
