The Cost of “Supersized” Meals
1. Using the Wendy’s online nutrition information sheet, create two meal options and compare the intake.

Macronutrient Distribution Ranges
2. Calculate the proportion of energy provided by a Sarah’s intake. Protein 97.19g; Fat 87.06g; Carbohydrate 312.88g
c. How many kcalories from each of the macronutrients is provided by Sarah’s diet?
Total

d. What proportion of the energy in her diet comes from each of the energy yielding nutrients?
NOTE: THE TOTAL SHOULD ADD UP TO 100%; 99%, OR 101% IS ALSO ACCEPTABLE (DUE TO ROUNDING).
Did Sarah’s diet fall into the Acceptable Macronutrient Distribution Range recommended by the Dietary Reference
Intakes? (p 356)
Alcohol counts for overall Kcalorie intake
3. Calculate how many of the 146 kcalories provided by a 12-ounce can of beer come from alcohol, if the beer contains
1 gram of protein and 13 grams carbohydrate. (Note: the remaining kcalories derived from alcohol.)
1 g protein

13 g carbohydrate =

kcal protein
kcal carbohydrate
kcal alcohol
How many grams of alcohol does this represent?
g alcohol
Knowledge is Power
4. Even a little nutrition knowledge can help you identify some bogus claims. Consider an advertisement for a new
“supper supplement” that claims the product provides 15 grams protein and 10 kcalories per dose. Is this possible?
Why or why not?
Estimated Energy Requirement (EER)
5. John is a 46 year old sedentary male who weighs 87 kg and is 1.75m tall. Approximately how many kcals would you
expect him to expend each day?
2|Page
6. John (above) has decided he would like to lose weight and has started doing 1 hour of physical activity each day to
bring his physical activity (PA) level up to active. How will this affect his EER?
7. Sarah is a 24 year old female who weighs 73 kg and is 1.57m tall. She has determined that her PA level is low active.
Calculate her EER.
8. Sarah (above) has lost 3kg over the last 3 months by watching her portion sizes. How will this affect her EER? What
are the implications of this change for people trying to lose weight?
Energy intake Comparison
9. Mike’s energy intake was 3369 kcal per day on his 3 day average intake. He is a 19 year old business student at
Mount Royal University who is 177cm tall, weighs 81kg and is very active. Compare his EER to his actual intake.
a. Calculated EER
b. Is it about the same, higher, or lower? How much?
c. Based on this observation, theoretically, should he be gaining, losing or maintaining weight?
d. Explain why (hint: provide numerical support). How much weight change is expected in one week (show
calculations)?
e. Discuss whether or not a change in kcal intake is needed and why (base this on your opinion as well as
scientific fact - BMI).
