Equation to Calculate Your BMR

  1. Men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years)
  2. Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)

What happens when metabolic rate increases?

However, the word metabolism is often used interchangeably with metabolic rate, or the number of calories you burn. The higher it is, the more calories you burn and the easier it is to lose weight and keep it off. Having a high metabolism can also give you energy and make you feel better.

It is shown that the decrease in muscle mass relative to total body may be wholly responsible for the age-related decreases in basal metabolic rate. Energy consumption by physical activity also decreases with atrophic changes of skeletal muscle. Thus, energy requirement in the elderly decreases.
