# Numbers you need to know for weight loss

In addition to your BMR, it is important to calculate your body mass index (BMI) to serve as a standard of where your weight stands and to quantify your goals and progress.  You can calculate your body mass index yourself or use a free internet BMI calculator.  By dividing your weight in kilograms (1 pound = 0.454 kilograms) by the square of your height in meters (1 inch = 2.54 cm), you will determine your body mass index.

For example, for a person 5 ft 6 in (66 inches) tall, who weighs 125 lbs the calculation would

look like this:
Height: 66 inches x 2.54 cm/inch = 167.64cm = 1.6764 m
Height squared: 1.7018 m x 1.7018 m = 2.810 m^2
Weight: 125 lbs x 0.454 kg/lb = 56.75 kg
So, BMI = 56.75 kg / 2.810 m^2 = 20.19
Once you calculate your BMI, compare your number to the following list to identify where you currently stand and your goal BMI:
Under 18.5 = Underweight
Between 18.5 and 24.99 = Normal
Between 25 and 29.99 = Overweight
Between 30 and 34.99 = Obese (Class 1)
Between 35 and 39.99 = Obese (Class 2)
40 and above = Extreme Obesity
By calculating your BMR and your BMI, you will have a well-informed start on your way to health and fitness.
