An excess of these hormones, a condition known as hyperthyroidism, typically leads to symptoms such as weight loss, heat intolerance, and increased heart rate, contrary to the statement in question.

Hyperthyroidism is a condition characterized by the overproduction of thyroid hormones, which accelerates the body's metabolism. Common symptoms include weight loss, increased appetite, anxiety, and palpitations. Understanding this condition is essential to correct the false statement regarding its effects on weight and heart rate.
Metabolic Rate
Metabolic rate refers to the rate at which the body converts food into energy. It is influenced by various factors, including thyroid hormone levels. An increased metabolic rate, often seen in hyperthyroidism, results in weight loss and increased heart rate, highlighting the importance of thyroid function in energy regulation.
