- 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.arrow_forwardA 45 year old Jenny wanted to determine if she is taking enough food to gain weight.

- Skeletal muscles account for approximately 43% of the typical body mass. At rest, they use about 18% of the BMR. Of the total energy burned by the skeletal muscle, only 25% is used for work, and this is the muscular efficiency. What happens to the remaining 75% of energy? Choose the best answer. It is reabsorbed and stored for later use. It is transferred as electrical energy from the muscle to muscle. It is converted to heat to warm the body. It is used to make more ATP.arrow_forwardFrom the table below which shows the metabolic rate for each activity, if a person with height 1.50m and weight of 60kg completed all these activities in one day.
