Body Fat and Eating Disorders
Health problems associated with dietary medical conditions have become a serious problem in the United States today. These conditions include both eating disorders and the obesity epidemic.
Obesity is a medical condition in which excess body fat has accumulated to the point that it may adversely affect a person’s health. Medically, obesity is defined as having a body weight exceeding 20% above their normal weight. Body composition is the percentage of fat, muscle, and bone that make up the human body. The excess of fat associated with obesity carries many health risks to the body. Obesity has been found to increase the risk of cardiovascular disease, diabetes, and stroke, among many other dangerous medical conditions. As a result, obesity has been linked to a severe decrease in life expectancy (on average, six to seven years), and ranks as one of the leading preventable causes of death worldwide. Obesity is caused by a person taking in more calories than they physically use throughout the day. Other factors can aid in this imbalance. As people get older, the body becomes less able to metabolize food efficiently. Women have a lower resting metabolic rate than men and are therefore more prone to being overweight. People also tend to be less active in today's lifestyle than in the past.
Eating disorders also severely affect a person’s health. Anorexia nervosa, bulimia nervosa, and binge eating disorder are the most commonly occurring eating disorders. Anorexia nervosa is a compulsive refusal to maintain a healthy body weight and obsessive fear of gaining weight. Anorexia victims often see themselves as overweight despite obvious evidence to the contrary and so they suffer from a chronic malnourishment which leads to severe dehydration and a lack of necessary nutrient in the body. Risk factors of anorexia include thinning of bones, mild anemia of the muscles, severe constipation, low blood pressure, brain and heart damage, lethargy, and infertility. Bulimia nervosa is characterized by binge eating followed by a compensatory act such as vomiting, excessive diuretics, and excessive exercise or fasting. Bulimia victims may maintain a healthy weight but, like anorexics, they fear gaining weight. The constant purging of food is dangerous to the body and is known to cause chronically sore throat, swollen salivary glands, decaying teeth, acid reflux, severe dehydration, and an electrolyte imbalance which can lead to a heart attack. Binge eating disorder is a persistent loss of control over a person’s eating resulting in obesity. The risk factors of binge eating disorder are the same as those associated with obesity.

...Cheryl L. Mclean WAOL Intro to Psychology Eating Disorders Chapters 12 and 13 February 18—24 Eating Disorders Have you ever known anyone personally who has had an eating disorder? Is this a disorder that only affects teenagers? I’m a soon to be 47 year old who can say in my life time at least one in every 10 of my friends have suffered from some sort of eating disorder. I can also say that a few of my friends who have had an eating disorder did not grow out of it by their adult years. It is sad to say but I have even witnessed how one of my girlfriends behavior even affected her 8 year old daughter. One morning when the child woke up, she complained about be very bloated and fat. This child did not have an ounce of fat on her. I remember at that time worrying that if this child is concerned about her weight at age eight how will she view her self image in her teenage years and will she result to the extreme measures that her mother has taken to remain slim. There are several types of eating disorders but the two most dangerous ones are Anorexia and Bulimia Nervosa. Anorexia People with anorexia have an extreme fear of weight gain and a distorted view of their body size and shape. As a result, they can't maintain a normal body weight. Some people with anorexia restrict their food intake by dieting, fasting, or excessive exercise. They hardly eat at all — and the small amount of food they do eat becomes an obsession (TeensHealth...

...Eating Disorders BEH/225 Stephanie Copp July 9, 2014 Julie Bruno Most people think that hunger is all in one’s stomach; however, research shows that this is not the case. Hunger is controlled by a complicated system of chemicals that transmit signals between one’s brain and the body. “The cells in the hypothalamus communicate with cells in other parts of the brain to coordinate the release and uptake of chemicals that help regulate how much and what you eat” (Kirby, Jane RD., 2014). Motivation seems to be the role of the primary drive for hunger, and motives is a category that has been identified as biological or primary; hunger and the managing of food intake. The hypothalamus is a small; however important, part of the brain. It controls motivation and emotion, such as hunger, thirst, sexual behavior, sleep, and body temperature. In the 1940s the Drive Reduction Theory of Motivation was widely used in explaining motivation, which states that the force behind motivation was the reduction of drives; hunger being an example of a drive. However this theory is not used much in today’s world. External and internal motivations both play a part in one’s eating habits, and they can affect one positively or negatively; internal motivations being one’s emotions and external motivations being our environment and culture. Negative effects such as over eating, not eating enough, or just poor eating habits can lead to eating disorders. Even though there is no one single...

With our cultures unrealistic views on what is beautiful the supper skinny models that woman see everywhere makes many people think that they have to live up to those standards.

...Eating Disorders The two main eating disorders faced are Anorexia and Bulimia. Anorexia Nervosa, commonly called Anorexia, is an eating disorder in which the person loses more weight than what is considered healthy. This may be through a lack of eating, extreme “dieting,” or excessive exercise. Bulimia Nervosa, or Bulimia, is when someone purges on food and in feeling guilty about it, makes their self throw up. This is a personal matter because I have seen what eating disorders do to people and I have had personal experience with Bulimia Nervosa. This is a public matter because 30 million men and women suffer from eating disorders. Out of these 30 million, only one in ten people is able to get help. Eighty-six percent of students report an onset of an eating disorder by age twenty. However, this can strike at any time. Forty to Sixty percent of elementary school girls are concerned about becoming fat. Some say it may just be a stage. However, another study was taken in college. Out of 185 female students, fifty-eight percent felt pressure to be a certain weight. With so much pressure to look a certain way or weigh a certain number, along with the pressure of fitting in and finding friends how can one person continue to be stable? This pressure may cause teens and adults to be unsocial. Most of the time, it makes them feel as if they aren’t good enough. Anorexia and Bulimia are mostly caused by insecurity. Because of their insecurity, they constantly push themselves to...

...would say, from what I have learned in my abnormal psychology class, your daughter might have something called bulimia, which is a type of eating disorder. A person with bulimia eats a lot of food in a short amount of time which is binging and then tries to prevent weight gain by purging or getting rid of the food. Purging might be done by: * Making yourself throw up * Taking laxatives, which you have found in her room. Laxatives can pills or liquids and speed up the movement of food through your body to produce a bowel movement more quickly, making it an easy and appealing way to lose weight. * Exercise excessively, as you have described People with bulimia often fall within the normal range for their age and weight. But their weak points are that they: * Fear gaining weight * Want desperately to lose weight * Are very unhappy with their body size and shape A person with bulimia may be thin, overweight, or have a normal weight. A person with bulimia is often very private so they can do things such as throwing up because the person with bulimia feels shame or disgust. This makes it hard to know if someone has bulimia. The warning signs to look out for are extreme weight loss through: * Using diet pills, or taking pills to urinate or have a bowel movement * Going to the bathroom all the time after eating (to throw up) * Exercising a lot, even in bad weather or when hurt or tired You may be able to recognize the signs of frequent throwing...

...Eating Disorders Research Paper | | | Eating disorders are sweeping this country and are rampant on junior high, high school, and college campuses. These disorders are often referred to as the Deadly Diet, but are often known by their more popular names: anorexia or bulimia. They affect more than 20% of females between the age of thirteen and forty. It is very rare for a young female not to know of someone with an eating disorder. Statistics show that at least one in five young women have a serious problem with eating and weight (Bruch, 25). The Deadly Diet appears to be a mostly female problem. Eating disorders are most common in the middle to upper middle class families. Currently, the incidence is much lower in females from the "blue collar" families. The Deadly Diet can begin anywhere from the ages of ten to thirty. The peak age for the beginning of the Deadly Diet in females is eleven to fifteen; the peak for males is between fifteen and eighteen (Bauer, 89). Most of the information on the Deadly Diet says that it is a problem of teenage girls, but as clinics have found, most of the people who come to get therapy are in their twenties and thirties. This may be because younger people are less likely to seek professional help. Most often it is the parent who brings the patient for help. Adults who have left home and had to deal with managing their lives usually tend to realize more clearly the need to seek help and make changes. Everywhere one looks today...

...Eating Disorders When people think of disorders the usually tend to think of mental or physical disorders, but eating disorders go right along with these disorders also. Eating disorders are characterized by a compulsive fixation with food, body weight, or self-image. This disorder is becoming more and more prevalent in the United States partially due to the media’s portrayal of what might be considered attractive. But the images of unrealistic “skinny” women that is shown on television, in magazines and across the Internet is only a small part of the contributing factors to eating disorders. Other contributing factors include “…low self-esteem, depression, substance abuse, and suicidal ideation” (Sue, Sue & Sue, 2009, p.445). Eating disorders not only affect adolescents but adults also. Both men a and women suffer from eating disorders, however women and girls are more likely to have a negative self image and engage in disordered eating patterns. Even though the population of the United States is becoming heavier, women are increasingly putting an emphasis on being thinner. Men also affected by distorted eating patterns, however with male adolescents and college-aged boys weight dissatisfaction revolves around being heavier and more muscular. When a person has a distorted eating pattern it could lead to other serious disorders like bulimia nervosa, anorexia nervosa, or binge eating.

Are all girls supposed to be tiny and twig-like, and are all guys supposed to have washboard abs? No, and if this were true, that is how we all would have been created. According to the NEDA website (2014) “everyone is different, and that is what makes people interesting, if everyone were the same then we would have no individuality." It is important that the message of being your own person, to embrace your individualism and love who you are gets to young adults and teenagers. When the message does not get across there are serious consequences such as the development of eating disorders. This paper will review the types of eating disorders, history of the disorders, how they may be diagnosed, signs and symptoms and possible treatment options.

...Eating disorders like anorexia and bulimia are a major problem in all the word. Thousands of teenage girls are dying, and it seems like nobody cares. Where are family and friends of these girls suffering with these problems? When we care about someone with an eating disorder, we have to help that person to get rid of that problem. The purpose of this paper is to explain why family and friends should help people with anorexia and bulimia. What family and friends should do is help solve their problem, to show they care about them, and the most important stop their death. The first thing you as a friend or as a member of the family should do to help people with anorexia or bulimia is to give them solutions to their illness. Though there is no simple solution or cure, there are types of medical care, individual therapy, group therapy, and self-help group therapy helpful in their progress of recovery. A person with this illness seems not to notice her problem or does not care about it. You should convince her or give her your support to face it. The second reason for helping people with eating disorders is to show you care about them. Anorexia and bulimia cause serious depressions. Victims of anorexia and bulimia feel lonely and that nobody cares about them.
