INSTRUCTIONS and NECESSARY INFORMATION FOR CORRECT CALCULATION: Calculate the total energy requirement for one day and the body mass index (BMI) of a female who is 5 feet, 6 inches tall and weighs 215 pounds. She consumes approximately 2800 kcalories every day.
Begin by making the following calculations for this individual which will be used in future calculations. Fill in all blanks.
Note: 2.2 pounds = 1 kilogram (kgm)
39.37 inches = 1 meter (m)
Convert body weight in pounds to weight in kilograms:
1. Divide body weight in pounds_________ by 2.2 = _____________(weight in kilograms).
Convert height in inches to height in meters:
2. Divide height in inches ___________ by 39.37 = ______________ (height in meters).
Total energy requirement for 24hrs is resting metabolic rate (RMR) + thermic effect of food (TEF) + energy required for physical activity.
3. RMR formula (choose only one if you complete both, your answer will be marked as incorrect):
For a female: Multiply 0.9 x weight in kgms ______x 24hrs = _________RMR kcalories
For males: Multiply 1 x weight in kgms _______ x 24hrs = ________RMR kcalories
4. Thermic effect of food (TEF) formula:
Multiply the estimate of total kcalories eaten in a day _______________by 10% or 0.1 to = ________________TEF
5. Physical activity.
This clients physical activity level is low. Determine her energy requirements using only one of the formulas below (if you complete all of them, your answer will be marked as incorrect):
Sedentary: 20% x RMR kcalories from above _________ = ___________kcalories
Low activity: 30% x the RMR kcalories from above _______= ___________kcalories
Active: 40% x the RMR kcalories from above __________ =__________ kcalories
Very active: 50% x the RMR kcalories from above ________= __________ kcalories
6. Add 3, 4 and 5 for total energy requirement for 24hrs = ___________kcalories

9. Divide weight in kgs.___________ by (m)2 ________ = _______________ BMI
English method:
10. Multiply body weight in pounds___________ x 705 = ____________.
11. Divide result of above calculation _________by height in inches______= ___________.
12. Divide results of above calculation ________ by height in inches _____= _________BMI
