Got this from one of the articles at Good Housekeeping. If you want to know your body mass index, here’s how:
Multiply your weight in lbs. by 705. Divide this number by your height in inches twice. If your BMI is:
below 19 – you are underweight
19 to 25 – you have a healthy weight
26 to 29 – you are considered overweight and are most likely to have an excess of body weight
but not necessarily body fat
30 to 39 – you are obese and have an excessively high proportion of body fat
over 40 – you are extremely obese which can increase your risk of death from any cause by 50% to 150%
