Explanation / Answer

3. The Basal metabolic rate or BMR of that person is 1900Kcal/day.

His daily energy expenditure is 50-70% of his BMR amount.

Thus, the amount of energy required for the person for his daily activity is-

Minimum energy need for daily activity (1909 X 0.5)Kcal/day= 955 Kcal/day

Maximum energy need for daily activity (1909 X 0.7)Kcal/day= 1336 Kcal/day.

4. Total daily energy requirement for the person is the sum of the BMR and the energy he required to perform his daily activities.

Then, Minimum Total daily energy is =(1909+955) Kcal/day=2864 Kcal/day

           Maximum Total daily energy is =(1909+1336) Kcal/day=3245 Kcal/day.

Thus the person requires 2864-3245 Kcal/day energy to maintain his daily activity.

To calculate the BMR of a person under mentioned formula can be used.

BMR= 66+ (13.7 X Body Weight in Kg) + (5 x Body height in cm)-(6.8 x age in year)
