The BMI Really Isn’t That Accurate Says Dr. Oz
Your BMI is the gold standard when it comes to discussing with your doctor about whether you may be normal, overweight or obese. But did you know that depending on your age and your sex that this dreaded little three-letter acronym may not be very accurate when it comes to assessing your risk of heart disease? According to Dr. Oz, forget about your BMI, it’s your B.Q. that you should be looking at.
These BMI Basics everyone should know. Your BMI is basically a measure of how thin or how thick your body is based on your weight and your height. The formula for calculating your BMI is illustrated below:
BMI = ( weight in pounds/ height in inches (squared) ) x 703
A person’s BMI is used by physicians and dieticians to discuss objectively with patients about their weight and the impact it can have on their health such as an increased risk of heart disease and diabetes.
In typical clinical settings, a person’s BMI categorizes them as underweight with a BMI lower than 18.5; normal with a BMI between 18.5 and 25; overweight with a BMI above 25; and obese if the BMI exceeds 30.
However, some are questioning the accuracy of BMI when used toward medical diagnosis―a point made based on that fact that the BMI was not originally meant as a numerical standard on health. Rather, it was originally designed as a way of classifying populations of people according to their average body size.
According to Dr. Oz, when it comes to diagnosing health, research is showing that your BMI may not be accurately reflecting your risk of weight-related diseases.
“New science says that your BMI may not be the best predictor for disease because it does not account for where on your body fat accumulates,” says Dr. Oz. “Doctors now know that the location of your fat is more important than the amount. And that could be the difference between life…and death.”
Goodbye BMI, Hello BQ!
To replace the gold standard BMI, Dr. Oz now tells viewers that they should be paying more attention to two other letters—their BQ or Body Quotient.
To calculate your BQ, all you need to do is use the BQ calculator on doctoroz.com and fill in five fields: height, weight, waist measurement, gender and age.
According to Dr. Oz, a person’s Body Quotient is an improvement over the BMI because it also factors in a person’s age and gender—which the BMI does not.
“The calculator starts off with looking at two things that are not normally part of your BMI―your age and your gender, which by the way folks, matters because where your fat is carried, is affected by those things,” says Dr. Oz.
Dr. Oz points out that to be sure to get an accurate waist measurement, run a measuring tape around your waist using your belly button as a guide so that you are measuring above the hips.
After plugging in the numbers and your sex, the calculator will give you a low number value ranging somewhere close to the negative and positive sides surrounding zero on a number scale.
A value of 0 is normal meaning that you have an average chance of developing heart disease. If the value is negative, like a -2, then you have a reduced risk of heart disease. But if your number is positive, then you are at an increased risk of heart disease compared to the rest of the population.
“If you are negative, it’s good. If you are positive…that’s not so good,” says Dr. Oz who points out that even though if your number is positive and thereby―bad, it’s still a good thing because now you know where your health risk level is at and can now take steps like dieting, exercise and taking medications to get your BQ where it needs to be.
