# Different ways to measure how many calories you need.

Posted Oct 21 2009 10:00pm
 Harris Benedict FormulaTo determine your total daily calorie needs, 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 moderatetely active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55 If you are very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725 If you are extra active (very hard exercise/sports & physical job or 2x training) : Calorie-Calculation = BMR x 1.9 Here’s how to figure out your BMR:English BMR FormulaWomen: BMR = 655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) - ( 4.7 x age in years ) Men: BMR = 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) - ( 6.8 x age in year )   Metric BMR FormulaWomen: BMR = 655 + ( 9.6 x weight in kilos ) + ( 1.8 x height in cm ) - ( 4.7 x age in years ) Men: BMR = 66 + ( 13.7 x weight in kilos ) + ( 5 x height in cm ) - ( 6.8 x age in years )Another method Mifflin-St. Joer equation. Weight in pounds must be converted to kilograms by dividing weight in pounds by 2.2. Height must be changed to centimeters by multiplying inches by 2.54. Plug your height and weight into the basic equation:9.99 x weight + 6.25 x height - 4.92 x age.Men then add 5; women subtract 161.The total is your approximate calories per day for resting metabolic rate. The RMR for a 40-year-old man who weighs 190 lbs and is 6'1" is 1800 calories per day. A 25-year-old woman who is 5'6" and 140 pounds has a basic calorie requirement of 1380. Because the equation is not completely accurate, real RMR may be slightly lower or higher.In addition to the RMR calories, each person needs additional calories for daily activities and exercise. A sedentary person will need fewer calories than an active person.Here’s a very simple method to get a caloric need:  The Quick Method calculation is as follows: BMR = body weight in lbs x 15 to 16 calories Lose Weight = body weight in lbs x 12 to 13 calories Gain Weight = body weight in lbs x 18 to 20+ calories  Or  Fat loss = multiply your bodyweight in pounds with 12 calories (12 x lb).Maintenance = multiply your bodyweight in pounds with 15 calories (15 x lb).  in great health and happiness Scott White Personal Power Training Professional Fitness TrainerB.S. in Kinesiology 480-628-1607 swhite@personalpowertraining.netwww.personalpowertraining.netwww.seotutorialprogram.com  14362 N.
