Harris Benedict Caloric Needs Calculation

Harris Benedict Equation

1)
Women:
655 +(4.35 x Weight in pounds) + (4.7 c high in inches) - (4.7 x age in years)

Men:
66 +(6.23 x Weight in pounds) + (12.7 c high in inches) - (6.8 x age in years)

2)
Multiply by Intensity Level
1.2 Sedentary Light/little exercise
1.375 Light Light exercise (1-3 days/week)
1.55 Moderate moderate(3-5 days/week)
1.7 Very Active Hard(6-7 days?week)
1.9 Extreme Hard dailiy exercise and/or physical job)

3)
For weightloss, subtract 500/day
For maintenance, subtract nothing
For gain, add 250-300 calories/ day

4)
Divide total by nubmer of meals you eat per day.

eg: I am 77" tall, weigh 220 work out moderately (3-5 days/ week) =
(((66+(6.23 * 220) + (12.7 * 77) - (6.8 * 37))*1.55)-500)/5) = 570 calories per meal based on 5 meals a day.

If I were to eat 6 meals a day then it would be 475/ meal.
