What is the Mifflin-St. Jeor equation for estimating RMR for women?

  1. RMR = 99.9 wt (kg) + 6.25 x ht (cm) - 4.92 x age (yrs) + 161

  2. RMR = 99.9 wt (kg) + 6.25 x ht (cm) - 4.92 x age (yrs) - 161

  3. RMR = 655.1 + 9.6 x wt (kg) + 1.8 x ht (cm) - 4.7 x age (yrs)

  4. RMR = 66.5 + 13.8 x wt (kg) + 5 x ht (cm) - 6.8 x age (yrs)

The correct answer is: RMR = 99.9 wt (kg) + 6.25 x ht (cm) - 4.92 x age (yrs) - 161

The Mifflin-St. Jeor equation for estimating resting metabolic rate (RMR) in women is correctly represented as RMR = 655.1 + 9.6 x weight (kg) + 1.8 x height (cm) - 4.7 x age (yrs). This equation takes into account several factors that influence metabolism, including weight, height, age, and gender, providing a more accurate estimation of RMR compared to older equations. In the context of assessing energy needs, this equation is particularly valuable for health coaches because RMR constitutes a significant portion of total daily energy expenditure (TDEE). Understanding how to calculate RMR accurately allows professionals to design tailored nutrition and exercise programs that reflect an individual's metabolic rate more closely. While the other provided choices differ in their numerical constants and coefficients, they do not align with the Mifflin-St. Jeor equation specifically designed for women. Therefore, understanding this equation is crucial for effective health coaching and supporting clients in their health and fitness goals.
