BIOD 121: CASE STUDY MODULE 3
EXAM Q & A
Fred has returned for his next visit.
Client: Fred
Age: 56
Height: 5 feet 10 inches Weight: 270 pounds
BMR calculations:
Males BMR= 66+(6.23 x weight in pounds) +(12.7 x height in inches) -(6.8 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
Calculate the Estimated energy requirements (EER) for a male who is 41
years old, 6 feet 2 inches tall, and 220 pounds with a Low Activity lifestyle.
Use BMR and an activity factor to find the EER.
Your Answer:
41+6+2+220= 269

EXAM Q & A
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
Male BMR = 66 + (6.23 x weight in pounds) + (12.7 x height in
inches) - (6.8 x age)
BMR= 66 + (6.23 x220) + (12.7 x 74) – (6.8 x 41)
Complete calculations in parenthesis first
BMR = 66 + (1370.6) + (939.8) – (278.8)
Then add and subtract
BMR = 66+1370.6+939.8-278.8=2097.6
BMR = 2097.6
Multiply the BMR x activity factor to find EER
, BIOD 121: CASE STUDY MODULE 3
EXAM Q & A
EER = 2097.6 x 1.2 =2517.12
EER = 2517 calories
Indirect calorimetry estimates a person’s energy requirements by
Correct Answer
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
1. Today you want to determine the amount of energy (calories)
that Fred should be ingesting daily to maintain his current weight.
Using the BMR formula, determine Fred’s BMR.
Your Answer:
Male BMR = 66 + (6.23 x 270) + (12.7 x 70) - (6.8 x56) = 2264 kcal/day
