Estimating Energy Needs Assignment Spring 2016

1)Personal Information

    1. Are you female or male?________
    2. What is your height (list in inches, centimeters, and meters)__________inches             centimeters

                meters

*To convert to inches multiply feet x 12 and add inches. Example: 5’8” = 5 * 12 = 60 + 8 = 68 inches.

*To convert inches to centimeters, multiply inches by 2.54. Example: 68*2.54 = 173 centimeters

*To convert centimeters to meters, divide by 100. Example 173 cm = 1.73 m

 

    1. What is your current body weight (list in pounds and kilograms):__________lbs.____________kg

* To convert pounds to kilograms, divide by 2.2. Example: 148 lbs/2.2= 67.3 kg

ANS: 180 / 2.2 = 81.8 kilograms

 

    1. What is your BMI?                        

Define your BMI                               (i.e. underweight, normal weight, overweight, obese)

*Use (weight in pounds)/height in inches2) x 703. Example: (148 lbs.)/ (68 inches x 68 inches) = (148/4624)

= 0.032 * 703 = BMI 22.5

 

    1. What is your physical activity (PA) factor? 

 

  1.  Calculate your basal metabolic rate (BMR)._________________calories/day____________________

*BMR equations use actual weight in kilograms, height in centimeters, and age in years.

* BMR calculations (page 241):

 

  1. Calculate your estimated energy needs (EER). _                           calories/day

EER equations use age in years, actual weight in kilograms, height in meters, and physical activity (PA) factor.

EER calculations (page 245):

Men: EER = [662-(9.53 x age)] + PA x [(15.91 x wt) + (539.6 x ht)] Women: EER = [354-(6.91 x age)] + PA x [(9.36 x wt) + (726 x ht)]

 

  1. Describe the difference between BMR and EER. What component of energy expenditure makes up the difference? Evaluate the value of your difference. Can you explain the difference in terms of your lifestyle?

 

 

  1. Based on this information and the information from chapter 8 how do you feel about your current body composition? Are the numbers you calculated (BMI, BMR, EER) descriptive of your health or your disease risk/status? Explain why or why not.

 

 

  1. Assume you wanted to lose weight or gain weight. Based on the often-used 3,500 kcal/lb rule of thumb, how many kcals would you add to or subtract from your current energy intake per day to change your body weight by 0.5 lb per week and how many weeks would it take to lose 10 lb?

 

 

 

  1. Read the article by Diana Thomas and co-workers (posted in content folder for this week in D2L Brightspace). Based on the information contained in the article, how valid is the 3,500 kcal/lb rule? Explain. According to Thomas and co-workers, would it take longer or shorter to lose 10 lb than you answered in 6?
