What is a Calorie?
What is a kcal?
• 1 kcal = 1 Calorie = 1000 calories. Common usage
in the US is that a calorie is the same as a kcal (as
far as nutrition labels). Other countries (esp.
European ones) tend to use kcal instead....which is
a more accurate term.
• kcalories is what you burn (called Calories, with a
capital "C"). People refer to kcals as calories with
a lower case c.
How much of the (3) main nutrients do
I need? - Diet Breakdown.
• Typical Diet – an average person should
consume:
– 15%
Protein
__________
– 55%-60% Carbohydrates __________
– 25%-30% Fats (lipids)
__________
Example: 2,000 Calorie Diet
300 calories from Protein
1,100 – 1,200 calories from Carbohydrates
500 – 600 calories from Fats
• Example: You eat a burger that is 564 calories.
Compare that to your recommended daily
intake, based on 2,000 kcals/day.
– Carbs. 39 grams x 4 = 156 kcal
– Fat
32 grams x 9 = 288 kcal
– Protein 30 grams x 4 = 120 kcal
Total
564 kcals
% of carbohydrates - 156 kcal/2000 = 7.8%
% of fat
- 288 kcal/2000 = 14.4%
% of protein
- 120 kcal/2000 = 6 %
Proteins – “Body Builders”

2014 New Food Labels
http://www.nytimes.com/2014/02/27/health/new-fda-nutrition-labels-would-make-serving-sizes-reflect-actualservings.html?hpw&rref=science&_r=0
The redesign would
change how serving
sizes are calculated
and displayed
Percent daily values
would shift to the left,
making them easier to
read. Some package
sizes would be
required to show both
“per serving” and “per
package” calorie and
nutrition counts.
Vitamin D and
potassium counts
would be required.
Vitamins A and C
would be optional.
Calorie counts would
be more prominent,
and the existing
“Calories from Fat”
line would be
removed.
The new design
would require
information
about added
sugars.

Go to Portion Distortion Site listed above:
Bring up portion distortion I (in red). Students guess the answers – compares food portion size,
calories and amount of exercise to make up the calorie difference from 20 years ago to today.
Bring up portion distortion II (in red). Students guess at the answers – compares food portion size,
calories and amount of exercise to make up the calorie difference from 20 years ago to today continued.
Top of the page select BMI. Students fill in their height and weight. Read the information about
BMI.
Go back to previous page and go to Menu Planner: Students fill in their food intake from the day
before. It will calculate the total calorie intake at the top of the page.
