Using the Mifflin–St Jeor equation, what is the approximate BMR for a male who weighs 70 kg, is 175 cm tall, and is 25 years old?

Using the Mifflin–St Jeor equation, what is the approximate BMR for a male who weighs 70 kg, is 175 cm tall, and is 25 years old?

• A. 1500 kcal/day
• B. 1600 kcal/day
• C. 1674 kcal/day
• D. 1800 kcal/day

Answer: (C)

The calculation uses the Mifflin–St Jeor equation for men: BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age (years) + 5. Plugging in 70 kg, 175 cm, and 25 years: - 10 × 70 = 700 - 6.25 × 175 = 1093.75 - 5 × 25 = 125, so −125 - +5 at the end Total = 700 + 1093.75 − 125 + 5 = 1673.75 kcal/day, about 1674 kcal/day. So the best choice is the one around 1674 kcal/day.

The calculation uses the Mifflin–St Jeor equation for men: BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age (years) + 5.

Plugging in 70 kg, 175 cm, and 25 years:

• 10 × 70 = 700

• 6.25 × 175 = 1093.75

• 5 × 25 = 125, so −125

• +5 at the end

Total = 700 + 1093.75 − 125 + 5 = 1673.75 kcal/day, about 1674 kcal/day.

So the best choice is the one around 1674 kcal/day.
