Obesity is not
always connected with a high BMI
July 21st, 2006
because a person weighs a lot, may not mean that they are obese.
Scientists from The Jackson Laboratory are questioning the accuracy of
the body mass index (BMI) rating which is determined by a ratio of a
persons height compared to their weight. Any person that has a BMI over
30 is classified as obese and is at higher risk for health problems.
scientists looked at genetics of mice to see how genetics influence the
amount of body fat a mouse can inherit. What they discovered is the
adiposity (amount of body fat) does not always correlate to having a
found that the genetic network affecting adiposity is separate from that
affecting overall body size," said Dr. Gary Churchill of Jackson
Laboratory, "providing strong evidence that a high weight is not
necessarily directly associated with a high percentage of fat."
Other methods to assess body fat more accurately may be with calipers or
alternative body fat analyzer. Or you could look in the mirror, if you
can pinch an inch, they you need to lose a little bit of weight. You
can use the BMI as more of an estimate, but if you are muscular, you
might have a lower BMI rating.
