Verified step by step guidance

Understand the concept of metabolic rate: Metabolic rate refers to the rate at which the body expends energy or burns calories. It is influenced by various factors including hormonal levels, physical activity, and nutritional status.

Identify the role of the thyroid gland: The thyroid gland produces hormones that regulate metabolism. Thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3), play a crucial role in determining the metabolic rate.

Examine hyperthyroidism: Hyperthyroidism is a condition where the thyroid gland is overactive, producing excessive amounts of thyroid hormones. This leads to an increased metabolic rate, causing symptoms such as weight loss, increased heart rate, and heat intolerance.

Consider the effects of a sedentary lifestyle: A sedentary lifestyle typically leads to a lower metabolic rate because physical activity is minimal, reducing the body's energy expenditure.

Analyze starvation and hypothyroidism: Starvation slows down the metabolic rate as the body conserves energy due to lack of food intake. Hypothyroidism, characterized by an underactive thyroid gland, results in decreased production of thyroid hormones, leading to a reduced metabolic rate.
