BMR (Basal Metabolic Rate)

Have you ever wondered what your body uses in calories for just staying alive.  Well you can work it out yourself.  There are many websites that have handy little calculators to do this for you, but the nerd in me wanted to know the formula behind them, so here it is.

Men – BMR = 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) – ( 6.8 x age )
Women – BMR = 655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) – ( 4.7 x age )

The formula to calculate BMR is accurate for the majority of people. However, it does not factor in muscle to fat ratio, because of this, it will underestimate the calories burned by persons with very muscular bodies and overestimate those burned by clinically obese people. If you fall into these categories, you should use a formula that calculates BMR for your body composition.

BMR will decrease with age and increase with weight and height.
