Lifestyle
Click the “?” symbol and read about the different lifestyle types. The way a person lives their days has a
general impact on the Cal/day that their body requires. Set the person settings for a 17-year-old male,
1.6m, 75 kg, 15% body fat, and is very sedentary.
1. As a very sedentary person, how many Calories/day are burned in total?
2. How many Cal/day are from the lifestyle type? (you can’t see it, so you’ll have to do the math)
3. Change the lifestyle to very active. How many total Cal/day are burned? How many Cal/day are
from his lifestyle?
Diet and Exercise:
Set the person parameters to your settings of gender, lifestyle, height, weight. The % fat slider will move
automatically.
1. Scan through the food catalog above the plate. Note the amounts each icon represents.
1 serving of beef is ___________________________ and has ________________ Calories
1 serving of mixed nuts is _____________________ and has ________________ Calories
1 serving of “Oreos” is _________________________ and has ________________ Calories
2. Drag your typical day’s food to the plate. Try to be as complete as possible and check the amounts
(you might need to drag multiple of the same thing). If you can’t find something, get the closest
possible when. When you are done, look at the Calories/day bars next to the plate.
a. How many total Cal/day do you eat?
b. Calculate the % calories you get from each: protein, carbs, fats?
c. How many total Cal/day do you use?
3. Add your daily activities. How many more Cal/day do you burn from exercise?
