Answer:
The complete question is given in the explanation box below and the solution is shown in the picture attached.
Explanation:
Mrs. Cook, a 65-year-old retired bank teller, has noticed that despite eating the same diet over the last 3 decades, she now has a tendency to gain weight if not careful. She doesn't think her activity level is the likely suspect because she exercises fairly regularly. She plays tennis on Tuesdays and walks her dog about 2 miles every day. Occasionally, she gets out of town with her nephew and his family for a hike in the mountains, and she easily keeps up with her nephew’s 5-year-old children.
Calculate Mrs. Cook's current EER at 65, and her EER 30 years ago when she was 35. Mrs. Cook is 5 feet 4 inches tall and weighs 135 pounds. Assume that her activity level has remained approximately the same sense as a bank teller she was standing and walking a lot for her job. Also, assume that despite the problems with maintaining weight, she has succeeded in keeping the same weight.
The Harris-Benedict equation for calculation of Resting Metabolic Rate (RMR) is as follows:
Adult females
RMR (kcal) = 655.1 + (9.6 × weight in kilograms) + (1.8 × height in centimeters) – (4.7 × age)
EER = RMR (from Harris-Benedict equation) × activity factor
Round the final number of kilocalories to the nearest whole number. During calculations, use numbers rounded to the first decimal place. Your answer should have two numbers, the current EER and the EER from 30 years ago, separated by a comma.
Answer:
2656.7 kcal/day when she was 35
2449.4 kcal/day when she is 65
Explanation:
Estimated energy requirements for women 19 years or older= 354.1 - (6.91 x age in years) + PAL x { (9.36 x weight in kg) + (726 x height in m) }
For Mrs. Cook,
PAL= 1.45 (she is very active on her job)
Height= 1.6256
Weight= 61.4kg
