Question

Use the Harris-Benedict equation to estimate your calorie needs. Show your calculations to explain how you arrived at your answer.

Answer 1

Sample Answer:

Brian is a 15-year-old boy who weighs 130 pounds and is 68 inches tall. He engages in moderate exercise.

Convert weight and height to the metric system.

Weight: 130 lbs. = 130 × 0.45 = 58.5 kg

Height:     68 in. = 68 × 2.54 = 172.72 cm

Calculate BMR.

For men, BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age in years) + 5 BMR = (10 × 58.5) + (6.25 × 172.72) − (5 × 15) + 5 = 1594.5 calories

Calculate daily calorie needs.

For moderate exercise, daily calories needed = BMR × 1.55 = 1594.5 × 1.55 = 2,471.475 calories

Answer 2

Answer:

$BMR_{women} = 1401.75$

Explanation:

According to Harris-Benedict equation the Basal metabolic rate of an organism can be calculated by using the following formula for both men and women -

$BMR_{men} = 10 * W + 6.25 * H - ( 5 * A) + 5$

$BMR_{women} = 10 * W + 6.25 * H - ( 5 * A) - 161$

Here, W is the weight in Kgs

H is the height in Cms

and A is the age in years

My weight is equal to $65$ Kgs

My height is equal to $167.64$ cms or $5.5$ feet

Gender - female and

Age is $27$ years

Substituting the given values in above equation, we get

$BMR_{women} = 10 * 65 + 6.25 * 167.64 - ( 5 * 27) - 161$

$BMR_{women} = 1401.75$
