Activity 3 – ENERGY BALANCE
Overview:
To evaluate the extent to which you are in energy balance, you need to calculate your estimated energy (kcal) requirement (EER) and compare it with your energy (kcal) intake (already calculated for you from your computer nutrient analysis). See chapter 10 in the textbook for a discussion of energy balance. For this activity, complete the worksheet below on energy balance.
Calculations:
1. Enter the following information showing all work):

1 in = 2.54 cm
|
100 cm = 1 m
|
or 1 in = .0254 m
|
||||
|
example: 55 in x 2.54 cm/in = 139.7 cm and 55 in x .0254 m/in = 1.397 m
|

|
1 lb. = 2.2 kg
|
example: 130 lb / 2.2 kg/lb = 59.09 kg

2. Determine your Estimated Energy Requirement (EER) by using the appropriate equation below. (See page 320 in the textbook for an example of how to use this method to calculate kilocalorie requirements.)
Estimated Energy Requirement Formulas:
Men 19 years of age and older:
EER = 662 – (9.53 x Age[years]) + PA x [(15.91 x Weight[kg]) + (539.6 x Height[m])]
Physical Activity (PA):
PA=1.00 Sedentary (typical daily activities only)
PA=1.11 Low Active (equivalent to walking 2 mile/day at 3-4 mph)
PA=1.25 Active (equivalent to walking 7 mile/day at 3-4 mph)
PA=1.48 Very Active (equivalent to walking 17 mile/day at 3-4 mph)
Women 19 years of age and older:
EER = 354 – (6.91 x Age[years]) + PA x [(9.36 x Weight[kg]) + (726 x Height[m])]
Physical Activity (PA):
PA=1.00 Sedentary
PA=1.12 Low Active
PA=1.27 Active
PA=1.45 Very Active
