America has become a society obsessed with appearance, especially weight. We are
conditioned
at a young age to believe the only way to be normal is to be thin. This norm is
projected to millions of
Americans each day through television, magazines, billboards and every other form of
media and
advertising. How are people to know acceptance and happiness with themselves and others
when
our culture propagates what the perfect body should be.
It is the search for the elusive, perfect body that has created a thirty-three
billion dollars a year
weight loss industry. Yet few reduce their body fat and even fewer maintain their weight
loss beyond
two to three years. This leads to yo-yo dieting and increased low self-esteem of people
constantly
struggling to become what they see as a normal member of society.
A problem that lies within this problem, is the chronically obese person. Obesity is
when one's body
wieght is 25-30% above normal. While overweight is 20-30 pounds over normal. Most
people,
including health care providers see the problem with obesity as eating too much and
exercising too
little. But in truth, for many obese people the problem lies with genetic
predisposition, metabolic
problems, binge eating or sometimes all. These factors make dieting virtually impossible
because
these problems are not ones that can be solved by simply cutting calories. Especially
the problem of
binge eating.
Compulsive "binge" eating in the obese is not caused by just wanting to eat. The
want to eat is
caused by looking for a sense of security. A sense of security wanted because there are
poor or no
coping skills for stress or depression and low self-esteem. Therefore, when a compulsive
overeater
or binge eater diet, the diet is doomed to fail because the weight returns when the
person resumes
normal eating. Thus creating an even greater depression.
Now many obese people have medical research to turn to as to why the weight they
lost usually
comes back. Recent research has strongly backed the set-point theory, which says that
when an
individual loses weight, the body's metabolic rate adjusts in order to return to the
baseline weight.
Research with animals has revealed a protein called leptin. Leptin circulates in
the blood and
signals the set point mechanism in the brain, which tells how much fat is present in the
body. The
protein is believed to be produced by an obesity gene called ob. When leptin is injected
into rodents,
it lessened appetite and increased calories being burned. However, leptin is still very
much in early
experimental stages, because even though it may gauge how much fat you have it does not
at this
point tell how much you want.
Another recent breakthrough was the discovery of unocortin. Unocortin appears to
suppress
appetite when the body is under severe stress. It is a cousin of the brain chemical that
generates the
body's "fight or flight" response. Unocortin was discovered at the Salk Institute, when
a researcher
was studying a neuropeptide which activates body stress reactors. He noticed receptors
in parts of
the brain where the chemical did not exist. However, it may be a long time before
unocortin is
actually a consumer drug. At this time, the only way unocortin works is to be directly
injected into the
brain. A company called Neurocin Biosciences, is already researching the brain receptor
unocortin
locks onto to work.
For now, the serotonin reuptake inhibitor drugs are the only diet drugs being used
in the U.S.
These drugs work by affecting eating behavior. Eating behavior is the result of a
mixture of
neurotransmitters. The link between serotonin and eating disorders was discovered in the
early
1980's. The serotonin inhibitors include Lovan, Redux and phen-fen (Phentermine and
Fenfluramine).
Phen-fen is the drug combination currently recieving so much attention. Phentermine is
similar to
an amphetamine and it works to increase metabolic rate. Fenfluramine(brand name
Pondimin) in-
creases the serotonin level, which decreases appetite. However, neither drug works
alone. They
only have optimum effect together.
Phen-fen is how I became interested in the research of new obesity drugs. I first
learned of
phen-fen in June. The article I read in the Knoxville paper about people who had taken
the medicine,
showed it to be what I and many others had been waiting for. I finally believed my real
chance to
lose weight had arrived. So with real anticipation, I made the two and half hour drive
to Monticello,
Kentucky. My first month on the medicine was great, I lost fourteen pounds and
completely lost any
desire to eat. The compulsion I normally felt late at night to snack was gone. My
problem with
phen-fen began the second month, when I started experiencing depression. One of the
possible
side effects mentioned was depression in people who had suffered clinical depression or
were prone
to depression. I knew this when I started the medicine, but I thought anything was worth
risking
if it meant losing weight. By the third month, the depression was worse and I had to
make a
decision. Was it really worth losing weight if it meant losing my mental stability?
I decided it was not worth it to me. When I made the decision, I could not believe
the choice I
made. My whole life has been spent wishing I had a different body. I thought that
losing weight
was somehow going to solve every problem I had. But when I realized I did not want to
be
depressed again, I realized that thin people have problems to and my problems would exist
no
matter what the size tag in my clothes read.
After I quit taking the medicine, the urge to eat whether I was hungry or not did
return. But I
have continued to fight the urges and so far have only gained a couple of pounds back
from what I
lost. Perhaps the thing I most of the medicine, was the energy and the feeling of
motivation.
Other side effects of phen-fen are dry mouth, dizziness, short-term memory loss, and
in some
the serious problem of pulmonary hypertension. The New England Journal of Medicine
presented
an editorial on the benefits and risk of phen-fen and other drugs in this class. The
physicians who
wrote the article, wrote that considering the health risks of obesity for some, that the
possible risk
for pulmonary hypertension did not outweigh the benefits of the drugs if used
appropriately.
Overall, I am glad I took the risk to try phen-fen. There was always the posibility
that the med-
icine might have worked for me. But I am also glad that I have an understanding of the
body's
metabolic nature and was able to recognize my symptoms for depression. For many others,
the lack
of understanding of what is going on in their body is why many who have tried phen-fen
have not
been successful with their experience. Therefore, it is the physician's responsibility
to completely
inform clients of all possible side effects and to thoroughly explain to them what is
going on in their
body while they are taking the medication. It is also anyone's responsibility who is
serious about
taking any medication of this sort, to find out for themselves what is going on and what
could
happen.
In this paper I have outlined various physical causes of obesity and possible
treatments for the
physical factors. But medication, exercise, healthy diet, none of these things will
effectively cause
permanent weight loss until a person is ready to be happy with their body and their
overall self.
You cannot successfully lose weight if you think your life is suddenly going to get
better after the
weight is gone. You have to want to do it because you love yourself and you want a
healthier
body. I think this is the most important thing I have finally learned about life and
about myself. I hope
that in the future there will be a time when people are not judged by their appearance,
therefore
those that think a different body will make them happy, will finally be able to be
believe their
worth is based on who they are and not what they look like.
