Body Mass Index (BMI) Calculator
|
People with a BMI of
27.0 or greater qualify for prescription weight loss drugs.
Body mass index (BMI) is a measurement based
on height and weight as it relates to body fat, and can be used to
determine how much risk a person has of developing certain health
problems because of his or her weight. As a point of reference,
someone with a BMI of 27 is approximately 20 percent overweight. The
higher the BMI, the greater the risk a person has to develop
additional health problems.
To calculate your BMI, enter your height in
feet and inches and your weight in pounds (lbs) in the boxes below

Cause
|
|
Obesity results when energy intake is greater
than energy expenditure. The excess energy is stored in the form
of body fat, which leads to weight gain. Reducing food intake
alone is not the key to weight loss. People must increase energy
expenditure along with decreasing energy intake. The Body Mass
Index (BMI) is a scale used for measuring obesity. The Food and
Drug Administration, the National Institutes of Health, and the
Institute of Medicine all recommend and use the BMI scale.
