Calculate the basal metabolic rate for a man who weighs 165 lb.

Answer :

The basal metabolic rate for a 165 lb man is approximately 1678 Calories per day.

To calculate the basal metabolic rate (BMR) for a man who is 165 lbs, we need to first convert his weight to kilograms (75 kg). Using the following reference data for BMR:

  • Body Surface Area (BSA) of the average person: 1.55 sq.m
  • Caloric Rate per sq.m/hr: 41 cal/sq.m/hr
  • The formula to find the BMR is: BMR = BMR/sq.m/hr × BSA × 24 hrs.
  • This translates to 41 cal/sq.m/hr × 1.55 sq.m × 24 hrs, which is approximately 1525.6 Calories/day.
  • Adding a 10% margin for basal energy requirements, the adjusted BMR becomes approximately 1678 Calories/day.

This calculation aligns with the reference that the average BMR ranges from 1750-1900 Calories/day for the average Indian man.
