A Light Lunch?
A Case In Calorie Counting
- Fats supply calories and essential fatty acids and help in the absorption of the fat-soluble vitamins A, D, E, and K. Provide more calories per gram than any other calorie source ( 9 calories per gram) (5)
- Have no double bonds. The body uses some saturated fatty acids for physiological and structural functions. There is no dietary requirement. (5)
- Unsaturated fatty acids that contain one or more isolated double bond - often hydrogenated - it solidifies fats. Found naturally in some foods and are formed during food processing. (5)
Carbs - 432.4 Calories
Protein - 150.4 Calories
Fat - 225 Calories
Total = 807.8 Cals
2.) After walking for 40 minutes at 2 miles per hour:
~ Elizabeth burned 213
~ Charonda burned 160 Calories
~ 1 Calorie = 1 Kilocalorie
~ 1000 Kilocalories = 1 calorie
~ 1 Calorie = 4.184 kJ
Calories, calories, kilocalories, and kilojoules
- x grams of carbs times 4 Cals/gram
- x grams of protein times 4 Cals/gram
- x grams of fat times 9 Cals/gram
Carbs - 271.2 Calories
Protein - 72 Calories
Fat - 61.2 Calories
Total = 404.4 Cals
3.) Someone with a lazier lifestyle should consume 2000 Calories per day. (both had a 600 Calorie breakfast) (3)
Elizabeth: consumed 40.39% at lunch
Charonda: consumed 20.2% at lunch
(body mass index)
Elizabeth's weight = 90.7 kg
Height = 1.6 meters
BMI: 90.7/(1.6 x 1.6) =
* In order for Elizabeth to be at a healthy weight, she must lose 65 pounds
6.) Mary would have a BMI of 36.3 ( she is the same height as Elizabeth and weighs 205 pounds)
7.) Elizabeth's waist is a 34 (inches) and 35 inches is associated with obesity related health risks
Type 2 Diabetes (high blood sugar)
Certain Types of Caner (breast, colon, kidney)
It is recommended that a person consume less than 10% of their Calories from saturated fats in a day. (3,5)
~ In Elizabeth's lunch alone, she consumed 11.6% of her Calories from saturated fats. She will be way over the recommended limit by the end of her day. She should replace the saturated fats with unsaturated ones.
Elizabeth did a good job with her cholesterol. The recommended value is 300 mg/day and she only consumed 33 mg at lunch. (3,5)
1.) What could Elizabeth do to get down to a healthy weight?
2.) Which macronutrient is the primary source of a person's Calories?
= energy required to increase the temperature of one gram of water by 1 degree Celsius (4)
= raises the temperature of a kilogram of water by 1 degree Celsius (4)
