BIOD 121: NUTRITION MODULE 3 EXAM Q & A

BIOD 121: NUTRITION MODULE 3 EXAM Q & A
 Direct calorimetry estimates a person’s energy requirements by:

Comparing the amount of oxygen consumed with the amount of carbon

dioxide expired

Measuring the heat produced in a sealed chamber

Comparing weight on land to underwater weight

Measuring the amount of fat deposited under the skin

 What range of BMI values represents a person with a healthy weight?

18.5 - < 25



 Calculate the Estimated Energy Requirement (EER) for a female who is 23

years old, 5 feet 4 inches tall, and 130 pounds with a sedentary lifestyle.

Use BMR and an activity factor to find the EER.

BMR Calculations:


Male BMR = 66 + (6.23 x weight in pounds) + (12.7 x height in

inches) - (6.8 x age)


Female BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in

inches) - (4.7 x age)


Physical Activity (PA) Estimates


1.2 = little to no exercise


1.375 = light exercise 1-3 days per week


1.55 = moderate exercise 3-5 days per week

1.725 = hard exercise 6-7 days per week

1.9 = hard daily exercise/job


Female BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in

inches) - (4.7 x age)


BMR = 655 + (4.35 x 130) + (4.7 x 64) – (4.7 x 23)


Complete calculations in parenthesis first

BMR = 655 + (565.5) + (300.8) – (108.1)

BMR = 1413.2


EER = BMR x activity factor

EER= 1413.2 x 1.2=

1695.84

EER= 1696 calories
