Question

Using the Harris-Benedict equation for women (below), estimate the resting metabolic rate of Mrs. Clements, who is 72 years old, is 157 cm tall, and weighs 53 kg. RMR = 655.1 + [9.563 x weight (kg)] + [1.85 x height (cm)] - [4.676 x age (years)]
a. 662 kcal
b. 1115 kcal
c. 1436 kcal
d. 1789 kcal
e. 1901kcal

Answer 1

Answer:

B. 1115 kcal

Explanation:

Resting Metabolic Rate is the total amount of energy (measured in calories) expended when the human body is at complete rest.

The formula for the Resting metabolic Rate according to the Harris-Benedict equation is given by

RMR = 655.1 + [9.563 × Weight (kg)] + [1.85 × height (cm)] - [4.676 × age (years)].

We simply substitute the figures into the equation, which gives us;

RMR = 655.1 + [9.563 × 53 kg] + [1.85 × 157 cm] - [4.676 × 72 years]

RMR = 655.1 + [506.839] + [290.45] - [336.672]

Applying BODMAS, we first sum up before subtraction.

Therefore;

1452.389 - 336.672 = 1115.717 kcal
