Measuring Body Mass
The new body mass index (BMI) applies to both men and women. To determine BMI, weight in kilograms is divided by height in meters, squared. To calculate your body mass index from the table below, locate your height in inches in the left-hand column, then follow it across until you locate your weight; the number at the very top is your body mass index. A BMI of 25 to 29.9 is considered overweight and one of 30 or above is considered obese.
