DETERMINING CALORIE REQUIREMENTS WITH THE HARRIS BENEDICT EQUATION (BEE)

Conversions:
Weight:   Pounds to kilograms, divide pounds by 2.2
Height:   Inches to centimeters, multiply inches by 2.54         

BEE Equations:
Male: 66 + (13.7 x weight in kg) + (5 x height in cm) – (6.8 x age in years) = BEE
Female: 665 + (9.6 x weight in kg) + (1.8 x height in cm) – (4.7 x age in years) = BEE

Activity Factors:

Sedentary Light
Active
Moderately Active
Very Active
Athletic                                                

 

BEE x 1.2= Calories required
BEE x 1.3= Calories required
BEE x 1.4= Calories required
BEE x 1.5= Calories required
BEE x 1.6= or more Calories required

EXAMPLE:
A 36 year old woman who is 5’6” and weighs 145 pounds. She goes to low-impact aerobics twice a week and enjoys going on walks with her husband on the weekend.

Conversions:
145 pounds divided by 2.2 = 65.9 kg
66 inches x 2.54 = 167.6 cm

Female BEE Equation:
655 + (9.6 x 65.9kg) + (1.8 x 167.6cm) – (4.7 x 36) = 1,420 kcal.

Activity Factor:
Estimated to be 1.4.   1,420 kcal x 1.4 = 1,988 Total kcal required per day.
