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/Ib)
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)
Lower Range:
Upper Range:
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:
Step 1: Convert pounds to kilograms
180 lbs / (2.2 kg/Ib)
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)

2. What is one factor that influenced the lower and/or upper range of
protein intake that you used in your calculations?
2. How does this calculated range compare to the estimated DRI range
identified above? (Higher, lower, similar)
3. Using Food Data Central (https://fdc.nal.usda.gov/index.html) from the
US Department of Agriculture, provide a combination/list of protein
sources that add up to meet the needs you have calculated above.
Please provide a link to each item you use. Please feel free to add more
lines to the table as needed.
