Which statement about the Mifflin-St. Jeor equation is most consistent with the material?

• A. It is less accurate than Owens equation
• B. It uses actual body weight
• C. It uses ideal body weight
• D. It ignores height

Answer: (B)

The Mifflin-St. Jeor equation estimates resting energy expenditure and uses actual body weight, along with height, age, and sex. Using actual body weight helps tailor the estimate to the person’s current size, which generally improves accuracy across a wide range of adults. Height is included to account for overall body size, and weight is not replaced by an ideal or adjusted weight. Because of these inputs, this equation is typically more accurate than older formulas that relied on ideal or different weight assumptions, and it is not correct to say it ignores height or that it’s consistently less accurate than the Owens equation.
