Question

Name: Fahad- very polite, educated and conscious about his health

•Age: 37 year

•Weight: 80 kg

•Height: 175 cm

• Office work with exercise(walking 3 times/week –60minutes)

-Calculate his energy requirements

-Plan a proper diet using the exchange list

Answer 1

• Energy expenditure is the sum of the basal metabolic rate (the amount of energy expended while at complete rest), the thermic effect of food (TEF, the energy required to digest and absorb food), and the energy expended in physical activity.

BMR for Men = 66.47 + (13.75 * weight [kg]) + (5.003 * size [cm]) − (6.755 * age [years])

66.47 + (13.75 * 80 + (5.003 *175) − (6.755 * 37)= 66.47+ (1100 + (875.525 - (249.935) )

66.47 + 1100 + 625.59

1792.06 cal = BMR

To calculate TEF simply multiply the BMR by 0.1.= 1792.06 * 0.1 =179.206 cal= TEF

Energy expended in physical activity is , 198 cal

Therefore energy requirement = 1792.06 + 179.206 + 198 = 2166.266 calories
