Which is NOT a factor listed for basal metabolic rate?

• A. Size.
• B. Age.
• C. Thyroid hormone.
• D. Exercise intensity.

Answer: (D)

Basal metabolic rate is the amount of energy the body needs at rest to support essential functions like breathing, circulation, and cell maintenance. It rises with larger body size because more tissue requires energy even at rest. It tends to decrease with age as lean body mass and hormonal activity change. Thyroid hormone sets the overall pace of metabolism by increasing or decreasing cellular activity. Exercise intensity, on the other hand, affects energy use during activity rather than the resting energy requirement used to determine BMR. So the item that is not a factor listed for basal metabolic rate is exercise intensity.
