Question

Basal Metabolic Rate (BMR) is the amount of energy your body uses to function at rest in a day. This includes the energy required to keep the heart beating, the lungs breathing, the kidneys functioning, and the body temperature stabilized. Approximately 70 percent of an individual’s energy expenditure goes into basal metabolism. The other 30 percent goes into digestion and absorption of nutrients (10%) and physical movement (about 20%). a. Calculate your basal metabolic rate in Calories using the appropriate equation here: Females: BMR = 655 + (9.6 × wt(kg)) + (1.8 × ht(cm)) – (4.7 × age(yrs)) Males: BMR = 66 + (13.7 × wt(kg)) + (5 × ht(cm)) – (6.8 × age(yrs)) b. Calculate how many Calories you burn overall in a day.

Answer 1

For an Average male, the weight is 65 kg, height is 170 cm and age is 25 yrs

Equation to calculate BMR for males is

BMR = 66 + (13.7 × wt(kg)) + (5 × ht(cm)) – (6.8 × age(yrs))

Substituting the values of weight, height and age

BMR = 66 + (13.7 x 65) + (5 x 170) - (6.8 x 25)

BMR = 1636.5 calories per day

It is given in question that 70% of an individual’s energy expenditure goes into basal metabolism.

therefore , Individual’s energy expenditure = BMR / 0.70

Individual’s energy expenditure = 1636.5 calories per day / 0.70

Individual’s energy expenditure = 2338 calories per day (approx.)
