* For men: BMR = 66 + (6.2w) + (12.7h) - (6.8a) x Activity Factor
* For women: BMR = 655 + (4.4w) + (4.7h) - (4.7a) x Activity Factor
w = weight in pounds
h = height in inches
a = age in years
Activity Factors
1.200 = sedentary (little or no exercise)
1.375 = lightly active (light exercise/sports 1-3 days/week)
1.550 = moderately active (moderate exercise/sports 3-5 days/week)
If you want to know how many calories you need in order to maintain your current weight, then use your current weight as w in the equation. Once you have your daily BMR, every 500 calories a day you add equals a 1 pound/week weight gain, or subtract 500 for weight loss
