Did You Inherit Fat Genes? The Truth About Biology And
Body Fat

"Battle Your Biology? Fat Chance," proclaimed a
headline recently in the health section of the New York Post
newspaper. Quoting new research and citing psychologists,
dietitians and physicians, the article says that more and
more evidence proves that your weight is genetically
determined, and if you're fat, "it's not your fault." "We've
known for a while that genes - more than environment and
behavior - explain obesity" argues Dr. James Rosen, an eating
disorder specialist and professor at the University of
Vermont.
While genetics are definitely a factor, believing you are
destined to be overweight for life because you've inherited
"fat genes" is the most disempowering and self-defeating
attitude you could ever adopt. The only way you’ll lose
weight permanently is to accept total responsibility for
yourself and acknowledge the fact that you have the power to
change, regardless what mother nature has given you to work
with.
There's no denying that heredity plays a major role in how
difficult it will be for you to lose fat. You inherited a
body type, a predetermined number of fat cells, a metabolic
rate and body chemistry just as you inherited your eye color
and hair color. In the 1930's, Harvard psychologist Dr.
William H. Sheldon developed a classification system for
these different body types called "somatotyping." While there
are no absolutes, Sheldon identified three basic somatotypes:
ectomorphs, mesomorphs and endomorphs.
Ectomorphs are the lean, lanky types. They are usually very
thin and bony, with fast metabolisms and extremely low body
fat. An ectomorph can eat like a horse without gaining an
ounce. Mesomorphs are the "genetically gifted." They are
lean, muscular and naturally athletic. Mesomorphs lose fat
and gain muscle with ease. Endomorphs are the "fat
retainers." Characterized by round features, excess body fat
and large joints ("big bones"), endomorphs usually have great
difficulty in losing body fat. They have slow metabolisms,
they are often carbohydrate sensitive, they gain fat quickly
if they eat poorly or don't exercise, and they lose fat
slowly - even on a healthy diet.
The tendency of endomorphs to store fat easily can be partly
attributed to metabolic problems. For example, endomorphs
often metabolize carbohydrates inefficiently. Normal people
can eat lots of carbohydrates - up to 60% of their total
calories - and they still stay lean. Endomorphs produce too
much insulin when they eat carbohydrates and this leads to
increased fat storage and difficulty in losing existing fat.
This condition is known as "insulin resistance" or "Syndrome
X."
Scientists claim that the tendency to gain weight easily may
also be due to chemical imbalances in the brain that cause
people to overeat. Researchers at Johns Hopkins recently
announced the discovery a compound called C75 that blocks an
appetite-regulating hormone in the hypothalamus. In mice
injected with the substance, 30 percent more weight was lost
because the drug caused the mice to eat less. More research
is planned to develop a similar appetite-suppressing drug for
humans. Unlike Xenical, which blocks fat absorption in the
intestine, this new drug would affect the brain's chemistry
so that people feel full sooner.
Many physicians and health professionals consider these
metabolic disorders and chemical imbalances as genetically
transmitted "diseases" that require medical treatment.
"Obesity is a disease and should be treated like one" says
Jackie Newgent, spokesperson for the American Dietetic
Association . This idea should be viewed with a great deal of
suspicion however, because weight loss is potentially the
biggest market in the world for drug sales.
According to Justin Gillis, a staff writer for the
Washington Post, more than 45 companies worldwide are trying
to develop new obesity drugs, and the stakes couldn't be
higher. Gillis writes, "In world where a blockbuster drug is
worth $1 billion a year in sales, analysts give $5 billion as
the low estimate for sales of an important obesity drug. If a
company developed a truly safe, effective weight loss drug,
and sold it for $3 a day to one quarter of the 97 million
American adults estimated to be overweight, sales would
exceed $26 billion a year in this country alone."
Basically, what the medical community is trying to tell you
is that if you are overweight, it's not your fault; you were
born fat, so don't feel guilty - and don't worry, we have a
drug that can "cure" you. Sounds like there's an ulterior
motive at work here, wouldn't you agree? Before you run to
get a prescription for the next "miracle" drug, you'd better
wonder whose interests are being served; yours or the
pharmaceutical giants.
Besides, drugs can never be the solution if they treat the
symptoms and not the cause. Drugs should be considered a last
resort for the morbidly obese who have already tried
everything else without success and who will face serious
health consequences if they don't lose weight. The editors of
obesity.com said it best: "Weight loss drugs do not take the
place of diet, exercise, patience, and perseverance."
"Dieting can be an uphill battle against your genes." says
Post writer Joyce Cohen. Unfortunately, if you're an
endomorph, Cohen is right. Losing weight is definitely easier
for some people than for others and that doesn't seem fair.
But that's the way life is. Life isn't fair. Let's be honest;
not everyone is going to become an Olympic Gold medallist, a
Mr. America or a fitness model. But don't despair - you are
not doomed to live a life of fatness if you don't have
"athletic genes."
Obesity is the result of many influences. Genetics is only
one of them. Like it or not, the primary cause of obesity is
your own behavior. Most of the factors that affect body
composition are entirely under your control. These factors
include how much you eat, what you eat, when you eat, what
type of exercise you do, how frequently you exercise, how
long you exercise and how hard you exercise.
If you have the genetic predisposition towards obesity, you
can lose fat like everyone else, you're just going to have to
work harder and longer at it than other people. "There is a
genetic component to weight," Says Dr. Thomas Wadden, a
psychologist from Syracuse University, "but no one is
destined to be obese. If weight has been a major problem in
your family, you may not be able to become as thin as you'd
like, but you can lose weight."
If you find losing weight to be a slow and difficult process,
the empowering thing to do is to look at it as asset, because
overcoming this obstacle will force you to develop
discipline, determination and persistence. These traits will
carry over to other areas of your life and make you a
stronger person all around. Arnold Schwarzennegger said,
"Strength does not come from winning. Your struggles develop
your strength. When you overcome hardships, that is
strength."
The first thing you must do if you want to lose weight or
succeed in any area of your life, is to accept complete
responsibility for your situation. In a short but powerful
little book called "As Man Thinketh," the author James Allen
wrote, "circumstances do not make a man, they reveal him."
What he meant was that we are not products of our environment
or our heredity (our "circumstances"), instead, we products
of our own thinking and belief systems.
We create our own circumstances through positive thinking and
positive action and we create negative circumstances through
negative thinking and lack of action or wrong actions. In
other words, we are responsible for where we are, what we
have and how our bodies look.
Some people get very angry with me when I tell them this:
They say, "Wait a minute. Are you trying to tell me that when
bad things happen to me, it’s my own fault? That I brought
unemployment, financial hardships, failed relationships,
weight gain or even health problems onto myself? Because if
that's what you're saying, that's totally unfair!"
Well, my friend, with very few exceptions, (some things
really are out of your control) that is exactly what I am
saying.
If you refuse to accept the fact that you are 100%
responsible for your weight, you will never be successful.
When people find themselves in undesirable situations or they
aren't getting the results they want, it’s all too easy to
make excuses: It's my genetics, I have big bones, I have a
slow metabolism, I don't have enough time to exercise, etc.
etc., etc. Making excuses is relinquishing control. It is
conceding that you a victim of circumstances instead of the
creator of your circumstances. Stop blaming and start taking
responsibility for your life. Take action! Start working out.
Eat better. Do something - do anything - but don't just sit
there on the couch and curse your chromosomes.
So, are you a frustrated "endomorph?" Do you feel like
dieting is an uphill battle against your genes? If your
answer is "yes," please don’t just quit and chalk in up to
"bad genetics," and don't believe that drugs are the answer
either - they're not. Your genetics will largely dictate your
athletic ability and how easily you will lose weight. That
doesn't mean you can't get lean; it only means that you're
going to have to adjust your diet and training to fit your
body type and you may have to work harder and be more
persistent than the "genetically lucky" ones.
Maybe obesity really should be classified as a genetically
inherited "disease." But frankly, if you have a "disease"
that forces you to learn more about exercise and nutrition,
to eat nutritious foods, to adopt a healthier lifestyle, to
develop a strong work ethic and to become a more persistent
person, that sounds like a blessing in disguise to
me.
