John has always had problems with maintaining his weight, and he is used to counting kilocalories and maintaining an active lifestyle. He has noticed that recently his diet of 2,500 kilocalories is no longer good for him. He is steadily gaining weight, and he has to go on a weight-loss diet from time to time to stay in shape. John is now 53; he is 5 feet 9 inches tall and weighs 168 pounds. He loves exercise. He bikes a 28-mile route with his cycling club on Mondays, plays volleyball on Thursdays, and runs 3 to 5 miles on other days. What is John’s EER and how many kilocalories should he consume to maintain his weight? The Harris-Benedict equation for calculation of Resting Metabolic Rate (RMR) is as follows: Adult males RMR (kcal) = 66.5 + (13.7 × weight in kilograms) + (5.0 × height in centimeters) – (6.8 × 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.

Expert Solution

In the question, it is mentioned that John is now 53; he is 5 feet 9 inches tall and weighs 168 pounds.

Therefore, John's age= 53 years

His height= 5 feet 9 inches= (512)+9 inches [ 1 foot= 12 inches]

= 69 inches

= 692.54 centimeters [ 1 inch=2.54 centimeters]

= 175.3 centimeters

His weight= 168 pounds = 1680.454 kilograms [ 1 pound= 0.454 kilograms]

= 76.2 kilograms

The Harris-Benedict equation for calculation of Resting Metabolic Rate (RMR) is for adult males,

RMR (kcal) = 66.5 + (13.7 × weight in kilograms) + (5.0 × height in centimeters) – (6.8 × age in years)

= 66.5 + (13.7 76.2) + (5.0 175.3) - (6.8 53) kilocalories

= (66.5 + 1043.9 + 876.5) - 360.4 kilocalories

= 1986.9 - 360.4 kilocalories

= 1626.5 kilocalories

We know that the value of activity factor for different peoples are,

Lifestyle Activity factor
Sedentary (little or no exercise) 1.2
Lightly active (light exercise 1-3 days/week) 1.375
Moderately active (moderate exercise 3-5 days/ week) 1.55
Very active ( exercise daily) 1.725

John bikes a 28-mile route with his cycling club on Mondays, plays volleyball on Thursdays, and runs 3 to 5 miles on other days, his activity factor 1.725

Now,

EER (Estimated Energy Requirement)= RMR (from Harris-Benedict equation) × activity factor

= 1626.5 1.725 kilocalories

= 2805.7 kilocalories

= 2806 kilocalories (approximately)

John's EER= 2806 kilocalories

He should consume 2806 kilocalories per day to maintain his weight.
