Portage Learning, BIOD 121 Nutrition – Module 3 Problem Set Question 1

Calculate the Estimated Energy Requirement (EER) for a female who is 23 years old, 5 feet 4 inches tall, and 130 pounds with a sedentary lifestyle. Use BMR and an activity factor to find the EER. BMR Calculations: Male BMR = 66 + (6.23 x weight in pounds) + (12.7 x height in inches) - (6.8 x age) Female BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) - (4.7 x age) Physical Activity (PA) Estimates 1.2 = little to no exercise 1.375 = light exercise 1-3 days per week 1.55 = moderate exercise 3-5 days per week 1.725 = hard exercise 6-7 days per week 1.9 = hard daily exercise/job Female BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) - (4.7 x age) BMR = 655 + (4.35 x 130) + (4.7 x 64) – (4.7 x 23) Complete calculations in parenthesis first BMR = 655 + (565.5) + (300.8) – (108.1) BMR = 1413.2 EER = BMR x activity factor EER= 1413.2 x 1.2= 1695.84 EER= 1696 calories In order to meet minimal nutritional requirements, what guidelines are given for the minimum number of calories men and women should consume per day? 1500 for men; 1200 for women Question 3 Children, teens, pregnant women, breast feeding women, short stature adults, very muscular individuals and the elderly. Understand the five important strategies in behavior modification. Be familiar with the terminology used to discuss Energy Balance What are some factors that can influence an individual’s BMR? (List at least 5) The BMR varies per person based on a number of factors such as; gender, lean body mass, body size, temperature, age, nervous system activity, caffeine, smoking, pregnancy, and diet. Be familiar with genetic (nature) and environmental (nurture) influences on a person’s weight. What shape has the greatest health risks and why? Apple, because the fat in the abdominal tissues interferes with the liver's ability to use insulin. What type of obesity is typically found in females? What body shape is associated with this particular obesity? Gynoid, pear What range of BMI values represents a person that is obese? 30 Which person is at a greater risk for health issues related to being overweight or obese? Janet has a BMI of 28 and a waist to hip ratio of 0.95. Fred has a BMI of 28.9 and a waist to hip ratio of 0.78. Janet. Both have a BMI that indicates being overweight, but Janet has a more at-risk waist to hip ratio as her value is greater than 0.8. By measuring the degree of resistance to an electrical flow Measuring the heat produced in a sealed chamber Comparing weight on land to underwater weight Measuring the amount of fat deposited under the skin Ignoring factors other than age, how does BMR change as a person grows older? What does this mean for their dietary intake? As we age our BMR declines by 1-2% per decade. If no change in diet or activity level occurs from one decade to the next, a slow weight gain will be the result. All of the following can be used to determine a person’s body fat percentage except Calipers Underwater weighing Electrical resistance Direct calorimetry What type of obesity is typically found in males? What body shape is associated with this particular obesity? Android, apple What are the three main components of a healthy weight loss program? Calorie control, exercise and behavior modification Calculate the Estimated energy requirements (EER) for a male who is 41 years old, 6 feet 2 inches tall, and 220 pounds with a Low Activity lifestyle. Use BMR and an activity factor to find the EER. BMR Calculations: Male BMR = 66 + (6.23 x weight in pounds) + (12.7 x height in inches) - (6.8 x age) Female BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) - (4.7 x age) Physical Activity (PA) Estimates 1.2 = little to no exercise 1.375 = light exercise 1-3 days per week 1.55 = moderate exercise 3-5 days per week 1.725 = hard exercise 6-7 days per week 1.9 = hard daily exercise/job Male BMR = 66 + (6.23 x weight in pounds) + (12.7 x height in inches) - (6.8 x age) BMR= 66 + (6.23 x220) + (12.7 x 74) – (6.8 x 41) Complete calculations in parenthesis first BMR = 66 + (1370.6) + (939.8) – (278.8) Then add and subtract BMR = 66+1370.6+939.8-278.8=2097.6 BMR = 2097.6 Multiply the BMR x activity factor to find EER EER = 2097.6 x 1.2 =2517.12 EER = 2517 calories Anthropometrics estimates a person’s percentage of fat by: Comparing the amount of oxygen consumed with the amount of carbon dioxide expired Measuring the heat produced in a sealed chamber Comparing weight on land to underwater weight Using a caliper Be familiar with medical procedures used in rare cases for those who need extreme measures to lose weight. Question 16 0 / 0 pts Indirect calorimetry estimates a person’s energy requirements by: Comparing the amount of oxygen consumed with the amount of carbon dioxide expired Measuring the heat produced in a sealed chamber Comparing weight on land to underwater weight Measuring the amount of fat deposited under the skin Direct calorimetry estimates a person’s energy requirements by: Comparing the amount of oxygen consumed with the amount of carbon dioxide expired Measuring the heat produced in a sealed chamber Comparing weight on land to underwater weight Measuring the amount of fat deposited under the skin What range of BMI values represents a person with a healthy weight? 18.5 - 25
