Question

The daily BMR (basal metabolic rate) in kilocalories for males based on the Harris–Benedict equation is given by:

• A. (655.1 + 9.6 W + 1.9 H - 4.7 A) × activity factor × injury factor
• B. (66.5 + 13.8 W + 5.0 H - 6.8 A) × activity factor × injury factor
• C. (66.5 + 14.8 W + 5.0 H - 6.8 A) × activity factor × injury factor
• D. (66.5 + 14.8 W + 1.9 H - 4.7 A) × activity factor × injury factor

Hint:

Use Harris–Benedict: (66.5 + 13.8W + 5.0H – 6.8A) is the classic form, sometimes rounded with 14.8 instead of 13.8 for weight. Always check the version used in exams.

Answer 1

The Correct Option is C

Step 1: Understanding Harris–Benedict equation.
The Harris–Benedict equation is a widely used formula for estimating basal metabolic rate (BMR), which represents the number of calories required to maintain basic body functions like breathing, circulation, and cell production at rest.
Step 2: Formula for men.
For men, the original Harris–Benedict formula is:
\[ BMR = 66.5 + (13.8 \times W) + (5.0 \times H) - (6.8 \times A) \] where \(W\) = weight in kilograms, \(H\) = height in cm, \(A\) = age in years.
Step 3: Multiplying with activity and injury factor.
To get the daily requirement, this basal value is multiplied with activity factor (to adjust for lifestyle/physical activity) and injury factor (to adjust for stress or trauma).
Step 4: Comparing with given options.
Only option (C) matches this equation exactly for males.
Final Answer:
\[ \boxed{(66.5 + 14.8W + 5.0H - 6.8A) \times \text{activity factor} \times \text{injury factor}} \]
