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%).
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))
Calculate how many Calories you burn overall in a day.
Which of the following definitions best describes an individuals Basal Metabolic Rate?
The amount of energy used while eating.
O The amount of calories required to support an active lifestyle.
O The ratio of total cholesterol / HDL.
(
The number of calories to keep a body functioning at rest.
Dave describes his level of physical activity as very sedentary. His 34 year old, 75 kg male friend who is vigorously physically active would have only a slightly higher daily energy requirement than Dave (32 year old, 136.1 kg) does. Explain why this would be the case despite Dave leading a very sedentary lifestyle.
