Having more than the recommended percentage of body fat increases health risks, whereas having more lean body mass does not. Having too much body fat increases a person's risk of developing a host of chronic health problems, including high blood pressure, heart disease, high blood cholesterol, diabetes, gallbladder disease, arthritis, sleep disorders, respiratory problems, menstrual irregularities, and cancers of the breast, uterus, prostate, and colon. Obesity also increases the incidence and severity of infectious disease and has been linked to poor wound healing and surgical complications. The more excess body fat you have, the greater your health risks. The longer you carry excess fat, the greater the risks; individuals who gain excess weight at a young age and remain overweight throughout life face the greatest health risks” (Wiley, 2014). “Assesses factors that influence the obesity epidemic are the result from an energy imbalance. This involves eating too many calories and not getting enough physical activity. Body weight is the result of genes, metabolism, behavior, environment...

...Body Fat and Eating Disorders April D Cook SCI 241 8/3/13 Sandi House Define body composition and the risks associated with excess body fat? “Body composition is the body’s relative amount of fat to fat free mass (Scott, 2008).” The less body fat you have the better you feel and the better your body moves. Having too much body fat can cause health risks such as cancer, diabetes and heart disease. If you have too much fat around your organs you could damage your liver. What are some factors that influence the obesity epidemic? After reading the research from the US National Library of Medicine, obesity is being affected by high fat foods, fast food intake, and too much television watching for long periods of time and not enough physical activity, and the portion size of foods being bought (Brantley 2005). What are some health problems associated with anorexia nervosa, bulimia nervosa, and binge-eating disorder? Anorexia nervosa can cause osteoporosis, brittle nails and hair, yellow and dry skin, muscle weakness, constipation, low blood pressure, brain damage, and organ failure and body weakness. People who become anorexic believe that they are over-weight ("What Are Eating Disorders?", 2011). Bulimia nervosa can cause sore throat, swollen glands, tooth decay and acid reflux, intestinal issues from laxative abuse, dehydration and heart attack. People who become bulimic fear becoming over-weight ("What Are Eating Disorders?", 2011). Binge-eating disorder can cause cardiovascular...

...Body Fat and Eating Disorders Paper 1 Week 8 Assignment: Body Fat and Eating Disorders Paper Savanna Engstrom SCI/241 August 26, 2012 Dr. Mike Collins Body Fat and Eating Disorders Paper 2 Body composition is the comparison between muscle and fat in a person’s body. A person’s weight could be high because of either large muscles or having too much extra fat. When a person is overweight because of excess fat, they are at risk of coming down with a variety of very dangerous and life threatening diseases. Excess fat can also cause a person to have a weaker immune system which leads to infections, slower wound healing, and complications during surgery. Extra fat poses a danger to women especially while they are pregnant, and their baby could be threatened as well. There are also psychological aspects of being overweight which can harm a person over time such as becoming depressed, dependent on others, unable to take care of themselves, and possibly developing eating disorders. There are so many factors these days that contribute to the world’s obesity epidemic. The two leading factors, in my opinion, are not eating healthy and not getting the appropriate amount of physical activity. These two factors work together because they go hand in hand: unhealthy food causes people to feel lazy and lack energy, so they sit around and play video games and watch TV rather than go out to play. There is also the fact that many people were never taught how to shop for...

...Body Fat and Eating Disorders Johhnny DOe SCI /241 April 12, 2013 Angela Hattaway 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...

When people have excessive “fat it can cause fat under the skin (subcutaneous fat) it carries less risk than fat is deposited around the organs in the abdomen.

...Body Fat and Eating Disorders SCI/241 Alvin Fuentes 9/29/2013 Our bodies are made up of water, carbohydrates, protein, fat, and various vitamins. Having too much fat can lead to health risks such as high blood pressure, diabetes, and heart disease. This can be especially true is a lot of the fat is located at your waist. Obesity has become an epidemic in our country, costing around 10% of our national medical budget. One in three adults and one in six children are considered obese. Obesity occurs when people consume more calories than they burn, but the problem can go deeper than that. Fast food is one reason why so many people are overweight. Foods are now higher in sugar and calories, and are often more processed than what we used to eat. There is also less chances for activity adults and children. Walking or biking to schools has become less practical, and many chances for children to get out and play have become scarce. It has become easier to stay in or drive where we need to go over getting out and exercising. Physical education in schools has also declined in the last few years. Low-income communities may also lack a quality grocery store and as a result have to result to eating less healthy foods. These factors all add together to create the obesity epidemic in our country. The three types of eating disorders are anorexia nervosa, bulimia nervosa, and binge-eating disorder. These disorders put you at a higher risk of having many different health problems. Anorexia...

...Body Fat and Eating Disorders Kathleen Hastings SCI/241 Nutrition March 26, 2013 Body Fat and Eating Disorders Body composition is the proportion of your body when it comes to fat and fat-free mass (Jennifer Scott, 2008). If you have a higher proportion of fat-free mass compared to a lower portion of body fat, then you have a healthy body composition. However, someone that has an excessive amount of body fat is not as healthy and actually has a better chance of suffering from high blood pressure, heart disease, high cholesterol, diabetes, and cancer (Jennifer Scott, 2008). Today’s society is actually going through an obesity epidemic. Instead of being outside all of the time and working or playing, the younger generation stays inside and plays video games. Another thing is that we are a generation of moving fast and being on the run 24/7. This leads people to make bad food decisions and eat a lot of fast food instead of cooking healthy food for their selves. Being constantly busy and on the go also means less time for exercise. These are all factors that go towards causing this obesity epidemic. As bad of a problem as America has with obesity, we also have a rather large problem with people being obsessed with how they look and getting eating disorders which also causes health problems. One eating disorder is anorexia nervosa; it is a disorder that is complex and has three main features. Those features are that you refuse to maintain a healthy body weight, the fear...
