BMI and Body Composition Assignment (10 pts.)
The risk of developing health problems has shown to significantly increase as BMI rates increase
above a certain threshold. However, BMI has shown to be less accurate with certain populations.
Body Mass Index
Instructions
Measure your height and weight, and record the results. Be sure to record the unit of
measurement.
Height:___5’10”_____
Weight:___175_____
Calculating BMI
1. Convert your body weight to kilograms by dividing your weight in pounds by 2.2.
Body Weight___175______ lbs. ÷ 2.2 = Body Weight____79.5______ kg.
2. Convert your height measurement to meters by multiplying your height in inches by 0.0254.
Height __70_____ in. x 0.0254 = Height ___1.778_____m
3. Square your height measurement.
Height ____1.778____m x Height ___1.778_____m = height
= 3.16
4. BMI equals body weight in kilograms divided by height in meters squared (kg/ ).
Body Weight____79.5______ kg. ÷ Height ___3.16_____

Harris-Benedict Equation (Estimated BMR)
Instructions
Go to
https://globalrph.com/medcalcs/harris-benedict-basal-metabolic-rate-calorie-calc/
Enter in your age, height, and weight and select the corresponding physical activity level.
Estimated BMR: ____1920________ kcal/day
# of calories required/day based on current activity level: _____2640_______ kcal/day
If you consume ___2640_________kcal/day you would maintain your current weight assuming
that you consistently maintained the same activity level. If you completely eliminate any
exercise (sedentary), you could consume __2304________ kcal/day without gaining weight.
Using the same age, height, and weight go through and
calculate the estimated number of
calories required per day
for each physical activity level. (
Note:
Copy the one you used for the
previous calculation into the corresponding blank below)
Sedentary: ____2304________ kcal/day
Mild Activity: ______2640______ kcal/day
Moderate Activity: ___2976_________ kcal/day
Heavy Activity: _____3264__________ kcal/day
Very Heavy - Extreme Activity _____3648_________kcal/day
Instructions
Calculate your BMR, based on your gender, by hand using the following equation:
BMR calculation for men (metric)
BMR = 66.47 + (13.75 x weight in kg) + (5.003 x height in cm) - (6.755 x age in years)
1920.78
BMR calculation for women (metric)
BMR = 655.1 + (9.563 x weight in kg) + (1.850 x height in cm) - (4.676 x age in years)
Do you see a difference between your hand calculated BMR and the BMR calculation from the
website?
No there is no difference, it is the same number.
