What is BMI?

BMI or Body Mass Index is a measurement tool to help you understand that if you are at a healthy wieght for your current height. BMI is a number based on your weight and height. In general, the higher the number, the more body fat a person has. BMI is often used as a screening tool to decide if your weight might be putting you at risk for health problems such as heart disease, diabetes, and cancer.

Who should use a BMI Calculator?

BMI measurement is applicable for both Men and Women of age above 18 years and less than 65 years. Muscle builders, long distance athletes, pregnant women, the elderly or young children should not use BMI for their health assesment. This is because BMI does not take into account whether the weight is carried as muscle or fat, just the number. Those with a higher muscle mass, such as athletes, may have a high BMI but not be at greater health risk. Those with a lower muscle mass, such as children who have not completed their growth or the elderly who may be losing some muscle mass may have a lower BMI. During pregnancy and lactation, a woman's body composition changes, so using BMI is not appropriate.

For most adults (age between 18 to 65 years), the BMI is a good way to get an idea of healthy weight ranges. But it’s not always the final word in deciding if a person is overweight or obese. There are other things to think about when judging how much someone should weigh. A person with a high BMI should be evaluated by a health care provider, who might use other factors such as skinfold thickness (a measure of body fat), waist size, evaluations of diet and family health problems, and other factors to find out if a person’s weight might pose a health risk.

BMI Score and Risk Factors

The BMI score means the following:

BMI Score Health Status
Below 18.5 Underweight
18.5–24.9 Normal
25.0–29.9 Overweight
30.0 and Above Obesity

Along with being overweight or obese, the following conditions will put you at greater risk for heart disease and other conditions:

  • High blood pressure (hypertension)
  • High LDL cholesterol ("bad" cholesterol)
  • Low HDL cholesterol ("good" cholesterol)
  • High triglycerides
  • High blood glucose (sugar)
  • Family history of premature heart disease
  • Physical inactivity
  • Cigarette smoking

For people who are considered obese (BMI greater than or equal to 30) or those who are overweight (BMI of 25 to 29.9) and have two or more risk factors, it is recommended that you lose weight. Even a small weight loss (between 5 and 10 percent of your current weight) will help lower your risk of developing diseases associated with obesity. People who are overweight, do not have a high waist measurement, and have fewer than two risk factors may need to prevent further weight gain rather than lose weight.

Talk to your doctor to see whether you are at an increased risk and whether you should lose weight. Your doctor will evaluate your BMI, waist measurement, and other risk factors for heart disease.

The good news is even a small weight loss (between 5 and 10 percent of your current weight) will help lower your risk of developing those diseases.
