Question
Part 1:
Karen is a 54-year-old female. She weighs 225 pounds and is 5’2”. Karen is not physically active and has a typical desk job. Based on this information about Karen, calculate her estimated energy requirement (EER) and BMI.
a.)Age:
b.)Physical Activity Factor: based on the chart below
c.)Weight in Kilos: 225, divided by 2.2 =
d.)Height in meters: 62, divided by 39.4 =
e.)Height in centimeters: 62, divided by 0.394 =
The EER calculations depends on the individual’s age and gender. Remember that height and weight for EER should be calculated in meters and kilograms. Using your answers from above, find Karen’s EER using the calculation below:
a = age
b = physical activity
c = weight in kilograms (kg)
d = height in meters (m)
EER Equation:
Females, 19 years old and over: EER = 354 - (6.91 x a) + b x {(9.36 x c) + (726 x d)}
Karen’s EER is:_________
Part 2:
Body Mass Index (BMI) = weight (pounds) x 703 OR BMI = weight (kg)
height squared (inches)2 height (m)2
Karen’s BMI is ____________
Her BMI classifies her as what? (underweight, normal weight, overweight, or obese) __________
Part 3:
Name 3 reasons why energy needs vary from person to person?
1.
2.
3.
Name 2 types of weight-loss behavior modifications?
1.
2.
Energy Requirement (EER)? What's Your Estimated Calculating your EER is a two-step process Using your answers from each part of step 1, complete the following calculation based on your gender and age 2. First, complete the information below a. My age is b. My physical activity during the day based on the chart below is 662 (9.53 x_x [(15.91+(5396 X 1.

My weight in pounds is d. My height in inches isExplanation / Answer
Answer
a.)Age: 54 years
b.)Physical Activity Factor = 1
c.)Weight in Kilos: 225, divided by 2.2 =225/2.2 = 102.27 kg
d.)Height in meters: 62, divided by 39.4 = 62/39.4 =1.57
Calculation of EER in female having age more than 19 years using following formula
EER = 354 - (6.91 x a) + b x {(9.36 x c) + (726 x d)}
=354 – (6.91 x 54) + 1 x{(9.36 x 102.27) + (726 x 1.57)}
=354 – (373.14) + 1 x {(957+ 1139)}
= -19.14 + 2096
EER =2076.86
BMR calculation
It is calculated as follows
BMI = weight (kg) x height (m)2
= 102 kg / (1.57)2
= 102 / 2.46
BMI = 41.38 ( obese)
Reasons for energy variation from person to person
1. The rate of basal metabolism
2. Composition of body
3. Physical activity
4. mental activity
2 types of weight-loss behavior modifications
1. Modifying Weight-Loss Goals
2. Exercise
3. Self-Monitoring
4. Prevention of Weight-Gain parameters
5. Lifestyle modifications
