To determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows:

1. If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2

2. If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375

3. If you are moderately active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55

4. If you are very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725

5. If you are extra active (very hard exercise/sports & physical job or 2x training) : Calorie-Calculation = BMR x 1.9

Mifflin-St Jeor Equation:
For men:
BMR = 10W + 6.25H – 5A + 5
For women:
BMR = 10W + 6.25H – 5A – 161
Revised Harris-Benedict Equation:
For men:
BMR = 13.397W + 4.799H – 5.677A + 88.362
For women:
BMR = 9.247W + 3.098H – 4.330A + 447.593
Katch-McArdle Formula:
BMR = 370 + 21.6(1 – F)W
where:
W is body weight in kg
H is body height in cm
A is age
F is body fat in percentage
