Harris Benedict Formula for Men
BMR = 66 + (13.7 X weight in kilos) + (5 X height in cm) - (6.8 X age in years)
Notes:
1 inch = 2.54 cm.
1 kilogram = 2.2 lbs.
Example of BMR
You are 25 years old
You are 6 feet tall
Your weight is 220 pounds
Your BMR is 66 + (1370) + (914) - (170) = 2180 calories
Harris Benedict Formula for Men - STEP 2
To determine your total daily calorie needs, now multiply your BMR by the appropriate activity factor, as follows:
If you are Sedentary - little or no exercise
Calorie-Calculation = BMR X 1.2
If you are Lightly Active (light exercise/sports 1-3 days/week)
Calorie-Calculation = BMR X 1.375
If you are Moderately Active (moderate exercise/sports 3-5 days/week)
Calorie-Calculation = BMR X 1.55
If you are Very Active = BMR X 1.725 (hard exercise/sports 6-7 days/week)
Calorie-Calculation = BMR X 1.725
If you are Extra Active (very hard daily exercise/sports & physical job or 2X day training)
Calorie-Calculation = BMR X 1.9
Total Calorie Needs Example
If you are lightly active, multiply your BMR (2180) by 1.375 = 2997
Your total daily calorie requirement is therefore 2997 calories.
This is the total number of calories you need in order to MAINTAIN your current weight.
