Calculating Carbohydrate Needs (8 points)
1. For our Case Study information above, our client is an active individual
who works out regularly, following a moderate exercise program of ~1
per day of low-to-moderate intensity exercise. Calculated his
estimated carbohydrate intake need:
180 lbs /(2.2 kg/lb)
=
Step 1: Convert pounds to kilograms
Step 2: Multiply the lower range and upper range of the
carbohydrate need for a moderate exercise program by kg of BM
(show your work)
Lower Range:
Upper Range:
65 g
68-118 g
2. How does this calculated range compare to the estimated DRI range
identified above? (Higher, lower, similar)
3. Describe one possible reason why this calculated carbohydrate need
differs from the DRI identified above.
Calculating Protein Intake (12 points)
1. Using the Case Study information on page 1, calculate an estimate
protein intake range for our client. Remember, our client is an active
individual who works out regularly, following a moderate exercise
program of "1 per day of low-to-moderate intensity exercise. We can
assume they participate in a combination of endurance and resistance
training types of activities.
Step 1: Convert pounds to kilograms
180 lbs/(2.2 kg/lb)
Lower Range:
Step 2: Multiply the lower range and upper range of the protein
need for a moderate exercise program by kg of BM (show your
work)
Upper Range:
2. What is one factor that influenced the lower and/or upper range of
protein intake that you used in your calculations?
