In the basal metabolic rate equation for men, which component is subtracted?

In the basal metabolic rate equation for men, which component is subtracted?

• A. The product of height and 12.7 is added.
• B. 66 is added as a constant.
• C. The product of age and 6.8 is subtracted.
• D. The product of weight and 6.23 is added.

Answer: (C)

In the BMR estimate using pounds and inches, aging reduces metabolic rate while bigger body size boosts it. The subtraction comes from the age component, which is age multiplied by about 6.8; this negative term lowers the total as age increases. The rest are added: a base constant (around 66), plus a weight term (roughly 6.2–6.23 times weight in pounds) and a height term (about 12.7 times height in inches). So the component that is subtracted is the age-related term.
