The Harris-Benedict equation, also known as the Harris-Benedict principle, is used to estimate what a person's BMR (basal metabolic rate) and daily requirements are. The person's BMR total is multiplied by another number which represents their level of physical activity. The resulting number is that person's recommended daily calorie intake in order to keep their body weight where it is.

This equation has limitations. It does not take into account varying levels of muscle mass to fat mass ratios - a very muscular person needs more calories, even when resting.

How to calculate your BMR

  • Male adults
    66.5 + (13.75 x kg body weight) + (5.003 x height in cm) - (6.755 x age) = BMR
    66 + ( 6.23 x pounds body weight) + ( 12.7 x height in inches ) - ( 6.76 x age) = BMR
  • Slightly active lifestyle - light exercise between once and three times per week
    Your daily calorie requirements are BMR x 1.375
  • Moderately active lifestyle - if you do moderate exercise three to five days per week
    Your daily calorie requirements are BMR x 1.55
