Harris-Benedict Formula Calculating BMR.

The Harris-Benedict Formula, Calculating BMR (Basel Metabolic Rate), is to find out the calories you need to stay the same weight you are.

If you want to loose weight then you adjust the calories – eat less calories.

You could lose weight by eating the same amount of calories but burning the calories from moving your body by doing the gardening, housework, walking, running, tennis, swimming or other sports and exercise.

So if you do little to no exercise then your calorie intake will be considerably less than if you are an athlete.

Give it a go.

Work out now using the formula below to work out the calories you need to stay the same weight or lose or gain weight.

1. Calculate your BMR (basal metabolic rate):
Women: BMR = 655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) – ( 4.7 x age in years )
Men: BMR = 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) – ( 6.8 x age in years )
2. Multiply your BMR by the appropriate activity factor, as follows:

Sedentary (little or no exercise): BMR x 1.2
Lightly active (light exercise/sports 1-3 days/week): BMR x 1.375
Moderately active (moderate exercise/sports 3-5 days/week): BMR x 1.55
Very active (hard exercise/sports 6-7 days a week): BMR x 1.725
Extra active (very hard exercise/sports & physical job or 2x training): BMR x 1.9
3. Your final number is the approximate number of calories you need each day to maintain your weight.
