The Effects Of A Healthy Low Calorie Restricted Diet And Aerobic Exercise On Obesity

An estimated 97 million adults in the United States are overweight or obese (Klein 2000). “"Affecting one in five Americans – or more than 22 percent of the U.S. population – obesity is one of the most pervasive health problems in our nation right now," said George L. Blackburn, M.D., Ph.D., associate professor of surgery and associate director of the Division of Nutrition at Harvard Medical School/Beth Israel Deaconess Hospital, Boston, Massachusetts. "We need to implement steps to slow the progression of this national epidemic” (NAASO 1999). But the problem of obesity does not only affect the United States. "We now know that the growing prevalence of obesity is creating major health problems worldwide," said Dr. James O. Hill, president of the North American Association for the Study of Obesity (NAASO) and Professor of Pediatrics and Medicine at the University of Colorado Health Sciences Center. Obesity was once regarded as unique to Americans, but it is now seen as a global health risk affecting developing and underdeveloped countries (AOA 2000). Obesity is increasing at an epidemic rate in the United States - 1.3% a year for women over 20. Rates of obesity among minority populations, including African-Americans and Hispanic Americans are especially high (AOA 2000). There is also a marked increase in obesity among children.

2.5 Body Mass Index,BMI, is a measure of our weight compared to our height. BMI can help determine whether they are at a healthy weight, overweight or obese individuals are at increased risk for many diseases, such as: heart disease, high blood pressure, high cholesterol, type-2 diabetes, and some types of cancer. With high BMI the individual would need to perform further assessments, start with a diet, physical activity, family history, change lifestyle.

In 2013-2014 37.7% of adults 20 years of age and older in the U.S were obese. Among racial ethnic groups white Non -Hispanics had the lowest rate of obesity at 36.4%. Black and Hispanics populations had rates of 48.4% and 42.6% nationally. The rate for Black non- Hispanic groups were 1.5 times higher than the rate for white non- Hispanic groups.("Healthy People 2020," 2014, p. 3).

Obesity in the United States continues growing alarmingly. Approximately 66 % of adults and 33 % of children and teenagers in the US are overweight. Obesity is the result of fat accumulated over time due to the lack of a balanced diet and exercise. An adult with a BMI (body mass index) higher than thirty percent is considered obese (Whitney & Rolfes, 2011, pg. 271).

Over the years obesity has become more and more prevalent in the United States. Currently, approximately 35% of Americans are obese. The Center for Disease Control statistics on obesity are alarming. They have reported the obesity rate to be higher in Non-Hispanic blacks than Hispanics. 47% to 42%, while 32.6% of Non-Hispanic whites are obese. In addition to ethnicity, the CDC looked at obesity among age groups. Obesity was found to be higher among middle-aged adults 40-59, rather than younger adults age 20-39. As far as socio-economic groups were considered, Non-Hispanic black and Mexican American men with higher incomes are more likely to be obese than those with low income. When genders were factored in, the opposite was found. Non-Hispanic

Obesity, or being overweight, is a common problem today. Walk down any street in America and a large majority of people seen will be overweight or obese. Obesity is determined by a measure of body mass index (BMI), which is an indicator of fat content in the body. The BMI score can be obtained by dividing weight in pounds (multiplied by 703) by height in inches squared. A BMI of 25 to 29.9 is considered overweight while a BMI of 30 or more indicates that one is obese. Being overweight affects nearly one third of the population of the United States, with another one third obese, and a portion of those are considered morbidly obese (a BMI of 40 or more). This statistic includes adults, adolescents, and school-aged children. Glassman, Glassman,

Obesity in the United States has been a serious problem affecting Americans and has been continually growing higher in numbers each year. American obesity has nearly doubled within the last 40 years and is now considered to be an epidemic that is affecting millions of people around the nation. According to the National institute of Diabetes and digestive and kidney Diseases, 31% of men and 35% of women are considered seriously overweight, along with 15% of children between the ages of six and nineteen are also overweight. The lack of physical inactivity and extreme poor dieting are catching up to almost the same threat as cigarettes and tobacco smoking. We as a nation are considered to be the fattest country in the world.

Obesity has been on the rise in America and is reaching all time heights. Obesity in America is at 27.7 percent and 1 in 5 children in America are obese currently and many will have to deal with it throughout their lifetime. With almost a third of our population struggling with this problem, the increasing obesity rates are becoming a major concern. Even though there isn’t a single answer to why obesity has become so prevalent, there are many contributing factors such as socio-economic status, the rise in technology, fast food, car culture, politics, socio-economic status, stress, and biology.

A tool known as BMI (body mass index) is used by medical providers to calculate an individual 's body mass index. It calculated by measuring a child’s weight and height and the found value is then compared to percentiles relative to other children of the same age and sex. For example, if a child aged anywhere from 2-19 is “more than 85% and less than 95%” they are considered overweight. (Center for Disease Control and Prevention, 2009). This tool is not a method used to diagnosis childhood obesity but it 's a valuable way to measure the prevalence of obesity worldwide.

The World Health Organization (WHO) defines body mass index (BMI) as a simple index of weight-for-height that is commonly used to classify overweight and obesity. To determine BMI, a person’s weight, in kilograms, is divided by the square of the person height in meters

Obesity has become increasingly more prominent in American society. The Unites States has even been termed an overweight nation. Some twenty to thirty percent of American adults are now considered obese (Hwang 1999 and Hirsch et al 1997). With this in mind, Americans constantly look around themselves determining their weight status as well as that of those around them. While some Americans do fit the healthy category, others enter the underweight, overweight, and even obese categories, all of which can be unhealthy.

BMI (Body Mass Index) is the value derived from weight and height of an individual. Having a BMI value of 25-30 is considered overweight and >30 is considered obese.

Obesity is an ongoing epidemic characterized by excessive amounts of body fat that may cause other health-related issues. “Approximately 1 in 3 U.S. adults and 1 in 6 children and adolescents are obese” (Reducing Obesity, n.d.). The rates of obesity have increased throughout the United States in people of all racial groups and genders. Obesity does not discriminate on ethnicity or gender. However, research shows that “Black and Latino populations have substantially higher rates of obesity than do White populations” (The State of Obesity, 2014).

BMI (Body Mass Index, kg/m2) is a measure of how much body fat one has. To prevent adult-onset obesity one could calculate and plot BMI once a year in all children and adolescents, use change in BMI to determine excessive weight gain in comparison to normal weight gain. This would help to recognize children with overweight problems early. If overweight is recognized early, it is easier to provide help and maybe change patients eating habits as well as their leisure time physical activity.

Obesity is not just a cosmetic concern; it also increases your risk for cancer, diabetes, heart disease, high blood pressure, and muscular skeletal disorders. It is estimated that obesity affects more than a third of the American adult population and seventeen percent of the American children population (Moores, 2005). Obesity has many definitions; one of the many definitions is a medical condition in which excess body fat has accumulated to the extent that it may have a negative effect on health. Obesity is a chronic disease, that can happen from many things, a few of those causes will be discussed throughout this essay. Obesity is calculated by body mass index. This body mass index is calculated a little
