FOCUS
ON,,.,..,..OBESITY
Obesity is
the
most
common
chronic disease
in
the
modern
society.
Obesity
results
form
an imbalanee be-
tween
energy intake and energy ex-
penditure. Genetic, environmental, and
behavioral factors
(poor
appetite con-
trol, unhealthy eating habits,
lack
of ex-
ercise)
all
inlluence
the
balance
be-
tween energy intake and
output.
When
intake exceeds output over
the
long
term,
the
excess energy
is
stored
as
fat.
Excess body fat, particularly when dis-
tributed
on
the upper body,
increases
the risk of hypertension, coronary ar-
tery disease,
non-insulin-dependent
diabetes
mellitus, gallbladder disease,
gout, and certain types of cancer (e.9.,
prostate cancer for men, breast cancer
for women, and colon cancer for both).
ln
our society, due to westernized
eating pattern and modernization
of
so-
ciety, people have too many chances
to intake excess calories than they are
supposed to
eat.
Even
a
slight excess
in
daily energy intake, such
as
the calo-
rie content of
a single
soda cracker,
would result
in a
2-pound weight gain
a
year.
At
any
given time,
up to
50% of
women
and
25o/"
of men are trying to
lose
weight.
Obesity not
only
causes
health problems, but also
represent
socioeconomic
disability.
A successlul
weight loss program should include in-
dividualized counseling, understanding
patients' physiological and psychologi-
cal conditions, and educational
ap-
proaches.
