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
