Estimate the resting metabolic rate of a 165-lb (75-kg) male using the Simplified Resting Metabolic Rate Formula.

The Simplified Resting Metabolic Rate Formula is: 
For males: RMR = 10 x weight (kg) + 6.25 x height (cm) - 5 x age (years) + 5

Using this formula, the estimated RMR for a 75-kg male would be: 
RMR = 10 x 75 + 6.25 x (175) - 5 x 30 + 5 
RMR = 750 + 1094 - 150 + 5 
RMR = 1699

However, the answer choices are in units of kcal/d, so we need to convert the RMR from kcal/min to kcal/d. There are 1440 minutes in a day, so: 
RMR = 1699 x 1440 / 1000 
RMR = 2447 kcal/d

The closest answer choice is B, 1,800 kcal/d, which is not the exact answer but is the best choice given the options provided.
