As some in the media
have reported, obesity
may be leveling off in most segments of the U.S. population.
Although about a third of the U.S. population is obese,
obesity appears to be holding constant. This might mean that some of
the efforts to head off obesity are working. But still, there might be
an unseen problem -- hidden fat
that is not usually measured. And bariatric centers might
want be at the forefront in the effort to tackle the problem.
According
to the Mayo Clinic, a person can have a normal BMI (body mass
index), but still be obese. The condition is called normal weight
obesity. BMI takes only a person's height and weight into
consideration, since BMI is computed by dividing a person's weight in
kilograms by the person's height in meters, then squaring the result.
Therefore, BMI does not measure the percentage of fat on the body.
Although BMI is
sometimes controversial, it is probably the most used measurement of
body weight. BMI categories have been established to indicate when a
person is of normal weight (a BMI between 18 and 25), when a person is
overweight (a BMI between 25 and 30), and when a person is obese (a BMI
over 30).
Indeed, at most
bariatric surgical centers, BMI is one of the key factors used to
determine if a person should be considered for bariatric surgery. For
example, at many centers, one must have a BMI of 40 or more before
bariatric surgery is recommended. With a BMI less than 40, a person
might be considered for bariatric surgery if the BMI is greater than
35, and the prospective patient suffers from comorbidities such as
diabetes or high blood pressure.
However, the prospect
of normal weight obesity may necessitate the inclusion of fat
percentage measurements when assessing body weight. And this is where
the expertise of bariatric centers could come into play. While there
are home methods for calculating body fat percentage, at this time, the
most
accurate method is probably done in a facility equipped to make
accurate body fat percentage measurements.
The relatively new
finding by the Mayo Clinic that a person of normal weight could be
obese identifies a problem that bariatric centers can equip themselves
to handle. Centers should become knowledgeable about the current
recommended fat percentages. The centers should also get involved in
the ongoing research to nail down more accurate fat percentage
classifications. At any rate, strategically inclined bariatric centers
should prepare to play an important role in helping potential clients
manage body fat percentage, as well as BMI.
