The Mifflin-St Jeor equation is used to estimate resting energy expenditure; what is the formula for men?

• A. REE = 9.5 × weight(kg) + 6.25 × height(cm) − 5 × age + 5
• B. REE = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 161
• C. REE = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 10
• D. REE = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5

Answer: (D)

The main idea is using the Mifflin-St Jeor equation to estimate resting energy expenditure from body size and age, with a sex-specific constant. For men, the formula combines weight and height with the age term, then adds a +5 to account for sex. Specifically, REE = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5. This matches the standard male constant of +5. The other options differ by using a different weight coefficient, applying the female constant (−161), or using an incorrect sex constant (+10), which is why they don’t fit. This calculation helps tailor daily caloric needs for nutrition planning.
