Question

Which of the following predictive equations has demonstrated the greatest accuracy in estimating actual resting metabolic rate in healthy obese and nonobese adults?

1: Owen using adjusted body weight
2: Harris-Benedict using actual body weight
3: Harris-Benedict using adjusted body weight
4: Mifflin-St. Jeor using actual body weight

Answer 1

The Mifflin-St. Jeor equation using actual body weight is recognized as the most accurate method for estimating the resting metabolic rate in both obese and nonobese adults. The correct option is 4.

Step-by-step explanation:

Among various predictive equations for estimating the actual resting metabolic rate (RMR) in healthy obese and nonobese adults, the Mifflin-St. Jeor equation using actual body weight is generally considered the most accurate.

Studies have shown that this equation, which takes into account a person's sex, weight, age, and height, tends to have a higher predictive accuracy compared with other equations, such as the Owen and Harris-Benedict equations. This is particularly true when looking to estimate the metabolic rate of both obese (adults with a BMI over 40) and nonobese adults.
