Temperament seems to be, at least in part,
genetically determined. Some personality types (obsessive-compulsive
and sensitive-avoidant, for example) are more vulnerable to eating
disorders than others. New research suggests that genetic factors
predispose some people to anxiety, perfectionism, and obsessive-compulsive
thoughts and behaviors. These people seem to have more than their
share of eating disorders. In fact, people with a mother or sister
who has had anorexia nervosa are 12 times more likely than others
with no family history of that disorder to develop it themselves.
They are four times more likely to develop bulimia. (Eating Disorders
Review. Nov/Dec 2002)
Studies reported in the New England Journal
of Medicine (3/03) indicate that for some, but not all, people
heredity is an important factor in the development of obesity
and binge eating.
Also, once a person begins to starve, stuff,
or purge, those behaviors in and of themselves can alter brain
chemistry and prolong the disorder. For example, both undereating
and overeating can activate brain chemicals that produce feelings
of peace and euphoria, thus temporarily dispelling anxiety and
depression. In fact some researchers believe that eating disordered
folks may be using food to self-medicate painful feelings and
A note about stress and overeating: New research suggests that there is a biological
link between stress and the drive to eat. Comfort foods — high
in sugar, fat, and calories — seem to calm the body’s response
to chronic stress. In addition, hormones produced when one is
under stress encourage the formation of fat cells. In Westernized
countries life tends to be competitive, fast paced, demanding,
and stressful. There may be a link between so-called modern life
and increasing rates of overeating, overweight, and obesity.

People with eating disorders tend to be
perfectionistic. They have unrealistic expectations of themselves
and others. In spite of their many achievements, they feel inadequate,
defective, and worthless. In addition, they see the world as
black and white, no shades of gray. Everything is either good
or bad, a success or a failure, fat or thin. If fat is bad and
thin is good, then thinner is better, and thinnest is best —
even if thinnest is sixty-eight pounds in a hospital bed on life
Some people with eating disorders use the
behaviors to avoid sexuality. Others use them to try to take
control of themselves and their lives. They are strong, usually
winning the power struggles they find themselves in, but inside
they feel weak, powerless, victimized, defeated, and resentful.
People with eating disorders often lack
a sense of identity. They try to define themselves by manufacturing
a socially approved and admired exterior. They have answered
the existential question, “Who am I?” by symbolically
saying “I am, or I am trying to be, thin. Therefore, I matter.”
People with eating disorders often are
legitimately angry, but because they seek approval and fear criticism,
they do not know how to express their anger in healthy ways.
They turn it against themselves by starving or stuffing.
Some people with eating disorders say they
feel smothered in overprotective families. Others feel abandoned,
misunderstood, and alone. Parents who overvalue physical appearance
can unwittingly contribute to an eating disorder. So can those
who make critical comments, even in jest, about their children’s
These families tend to be overprotective,
rigid, and ineffective at resolving conflict. Sometimes mothers
are emotionally cool while fathers are physically or emotionally
absent. At the same time, there are high expectations of achievement
and success. Children learn not to disclose doubts, fears, anxieties,
and imperfections. Instead they try to solve their problems by
manipulating weight and food.
In addition, research suggests that daughters
of mothers with histories of eating disorders may be at higher
risk of eating disorders themselves than are children of mothers
with few food and weight issues.
According to a report published in the
April 1999 issue of the International Journal of Eating Disorders,
mothers who have anorexia, bulimia, or binge eating disorder
handle food issues and weight concerns differently than mothers
who have never had eating disorders.
Patterns are observable even in infancy.
They include odd feeding schedules, using food for rewards, punishments,
comfort, or other non-nutritive purposes, and concerns about
their daughters’ weight.
Still to be determined is whether or not
daughters of mothers with eating disorders will themselves become
eating disordered when they reach adolescence.
Also, if mothers and fathers preach and
nag about junk food and try to limit their children’s access
to treats, the children will desire and overeat these very items.
A recent study (Am J Clin Nutr 2003;78:215) indicates that when
parents restrict eating, children are more likely to eat when
they are not hungry. The more severe the restriction, the stronger
the desire to eat prohibited foods. These behaviors may set the
stage for a full blown eating disorder in the future.
Sometimes appearance-obsessed friends or
romantic partners create pressure that encourages eating disorders.
Ditto for sorority houses, theatre troupes, dance companies,
school cliques, and other situations where peers influence one
another in unhealthy ways.
People vulnerable to eating disorders also,
in most cases, are experiencing relationship problems, loneliness
in particular. Some may be withdrawn with only superficial or
conflicted connections to other people. Others may seem to be
living exciting lives filled with friends and social activities,
but later they will confess that they did not feel they really
fit in, that no one seemed to really understand them, and that
they had no true friends or confidants with whom they could share
thoughts, feelings, doubts, insecurities, fears, hopes, ambitions,
and so forth. Often they desperately want healthy connections
to others but fear criticism and rejection if their perceived
flaws and shortcomings become known.
In Westernized countries characterized
by various forms of competition, and in pockets of affluence
in developing countries, women often experience unrealistic cultural
demands for thinness. They respond by linking their self-exteem,
or self-disgust, to their weight.
Cultural expectations can be cruel and
unrelenting. “In order for a woman to consider herself happy,
she has to be in a good relationship, be happy with her kids,
her friends have to like her, her job has to be going well, her
house has to look really good — and she has to be thin.”

Quote: Advertising has done more to cause the social unrest of the 20th century than any other single factor. –Clare Boothe Luce, American author and diplomat (1903-1987)
People in western countries are flooded by media words and images. An average U.S. child, for example, sees more than 30,000 TV commercial each year (TV-Turnoff Network, 2005). That child watches more than 21 hours of TV each week plus dozens of magazines and many movies every year. In those media, happy and successful people are almost always portrayed by actors and models who are young, toned, and thin. The vast majority are stylishly dressed and have spent much time on hair styles and makeup.
Factoid: According to Health magazine, April 2002, 32% of female TV network characters are underweight, while only 5% of females in the U.S. audience are underweight.
In contrast, evil, stupid, or buffoonish people are portrayed by actors who are older, frumpier, unkempt, perhaps physically challenged. Many are fat.
Factoid: Again according to Health magazine, only 3% of female TV network characters are obese, while 25% of U.S. women fall into that category.
Most people want to be happy and successful, states that require thought, personal development, and usually hard work. The media, especially ads and commercials for appearance-related items, suggest that we can avoid the hard character work by making our bodies into copies of the icons of success.
Reading between the lines of many ads reveals a not-so-subtle message — “You are not acceptable the way you are. The only way you can become acceptable is to buy our product and try to look like our model (who is six feet tall and wears size four jeans — and is probably anorexic). If you can’t quite manage it, better keep buying our product. It’s your only hope.”
The differences between media images of happy, successful men and women are interesting. The women, with few exceptions, are young and thin. Thin is desirable. The men are young or older, but the heroes and good guys are strong and powerful in all the areas that matter — physically, in the business world, and socially. For men in the media, thin is not desirable; power is desirable. Thin men are seen as skinny, and skinny men are often depicted as sick, weak, frail, or deviant.
These differences are reflected in male and female approaches to self-help. When a man wants to improve himself, he often begins by lifting weights to become bigger, stronger, and more powerful. When a woman want to improve herself, she usually begins with a diet, which will leave her smaller, weaker, and less powerful. Yet females have just as strong needs for power and control as do males.
Many people believe this media stereotyping helps explain why about ninety percent of people with eating disorders are women and only ten percent are men.
In recent years it has become politically correct for the media to make some effort to combat eating disorders. We have seen magazine articles and TV shows featuring the perils and heartbreak of anorexia and bulimia, but these efforts seem weak and ineffective when they are presented in the usual context. For example, how can one believe that a fashion magazine is truly motivated to combat anorexia when their articles about that subject are surrounded by advertisements featuring anorexic-looking models? How can one believe that the talk show hostess is truly in favor of strong, healthy female bodies when she frequently prods her stick-like thighs and talks about how much she wants to lose weight from her already scrawny body?
In May 1999, research was published that demonstrated the media’s unhealthy affect on women’s self-esteem and body awareness. In 1995, before television came to their island, the people of Fiji thought the ideal body was round, plump, and soft. Then, after 38 months of Melrose Place, Beverly Hills 90210, and similar western shows, Fijian teenage girls showed serious signs of eating disorders.
In another study, females who regularly watch TV three or more nights per week are fifty percent more likely than non-watchers to feel “too big” or “too fat.” About two-thirds of the TV-watching female teens dieted in the month preceding the survey. Fifteen percent admitted vomiting to control their weight. TV shows like the two mentioned above are fantasies, but all over the world young women, and some not so young, accept them as instructions on how to look and act. That’s really a shame.
An important question for people who watch TV, read magazines, and go to movies — do these media present images that open a window on the real world, or do they hold up a fun house mirror in which the reflections of real people are distorted into impossibly tall, thin sticks (or impossibly muscular, steroid-dependent male action figures)? Media consumers need to be wise consumers of visual images.
And wise consumers of verbal images too. The impact on vulnerable, insecure people cannot be calculated when they hear celebrities say things like “Whenever I watch TV and see those poor starving kids all over the world, I can’t help but cry. I mean I’d love to be skinny like that, but not with all those flies and death and stuff.” –Mariah Carey
For more information on this topic, we recommend “Remote Control Childhood? Combatting the Hazards of Media Culture,” a book by Diane Levin. In addition, parents can help their children learn to think critically by teaching them to ask the following questions about material presented through the media:
- Who created the message?
- For what purpose? (It’s often to sell something. Sit-coms, for example, are considered “bait” by the TV industry to attract viewers who can then be shown commercials.)
- Does the message make me want something? Who benefits if I do want this thing and pay to get it?
- Is the message accurate or true?
- What lifestyles and values are presented? Which ones are omitted?
- Who are the so-called experts? Paid actors or real people?
- If research is cited, is it real science or just surveys and annecdotes?

If people are vulnerable to eating disorders,
sometimes all it takes to put the ball in motion is a trigger
event that they do not know how to handle. A trigger could be
something as seemingly innocuous as teasing or as devastating
as rape or incest.
Triggers often happen at times of transition,
shock, or loss where increased demands are made on people who
already are unsure of their ability to meet expectations. Such
triggers might include puberty starting a new school, beginning
a new job, death, divorce, marriage, family problems, breakup
of an important relationship, critical comments from someone
important, graduation into a chaotic, competitive world, and
There is some evidence to suggest that
girls who achieve sexual maturity ahead of peers, with the associated
development of breasts, hips, and other physical signs of womanhood,
are at increased risk of becoming eating disordered. They may
wrongly interpret their new curves as “being fat” and
feel uncomfortable because they no longer look like peers who
still have childish bodies.
Wanting to take control and fix things,
but not really knowing how, and under the influence of a culture
that equates success and happiness with thinness, the person
tackles her/his body instead of the problem at hand. Dieting,
bingeing, purging, exercising, and other strange behaviors are
not random craziness. They are heroic, but misguided and ineffective,
attempts to take charge in a world that seems overwhelming.
Sometimes people such as diabetics who
must pay meticulous attention to what they eat become vulnerable
to eating disorders. A certain amount of obsessiveness is necessary
for health, but when the fine line is crossed, healthy obsessiveness
can quickly become pathological.
Perhaps the most common trigger of disordered
eating is dieting. It is a bit simplistic, but nonetheless true,
to say that if there were no dieting, there would be no anorexia
nervosa. Neither would there be the bulimia that people create
when they diet, make themselves chronically hungry, overeat in
response to that hunger, and then, panicky about weight gain,
vomit or otherwise purge to get rid of the calories.
Feeling guilty and perhaps horrified at
what they have done, they swear to “be good.” That
usually means more dieting, which leads to more hunger, and so
the cycle repeats again and again. It is axiomatic in eating
disorders treatment programs that the best way to avoid a binge
is to never, never allow oneself to become ravenously hungry.
It is far wiser to be aware of internal signals and respond to
hunger cues early on by eating appropriate amounts of nourishing,
