As defined by the CDC, an individual is considered obese when they have a BMI of 30.0 or higher. BMI stands for body-mass index, and is used as a standard for measuring the % body fat of an individual.(CDC, 2014) In addition to being overweight, obesity comes with a myriad of other health risks including: high blood pressure, stroke, type 2 diabetes, and cancer.(NIH, 2012) In 2013, a study focusing on the relationship between concentrations of hydrogen and methane in an individual’s breath and the individual’s body weight happened upon a startling discovery. Conducted by Dr. Ruchi Mathur of Cedars-Sinai Medical Center, the study examined the breath of 792 people. There were four distinct sets of results. One group had normal concentrations of both gases, one with higher concentrations of hydrogen, one had higher concentrations of methane, and lastly one group had higher concentrations of both gases. All things aside, the individuals with higher concentrations of both gases also had notably greater BMIs than the rest.(Mathur, 2013) Focusing on obesity, this group is the one of greatest interest. This higher concentration of methane is connected
More and more scientists are trying to find links between HFCS and several major health problems; such as diabetes and obesity. Although a major link has
Obesity is when a person has excess body fat. It is calculated by dividing one’s weight by his or her height to get the body mass index (BMI=kg/m^2). This number is also used to screen for health problems that maybe be caused by certain weight categories. A BMI of 25-29.9 is considered to be overweight and over thirty is considered obese. A third of children are overweight (CDC, 2014). Obesity leads to significant physical and mental health consequences. Obese children are at risk for bone and joint problems, sleep apnea, type two diabetes, high cholesterol, coronary artery disease and hypertension (CDC, 2014).
Obesity is usually defined by using the body mass index (BMI). A persons BMI is worked out by dividing the persons weight in kilograms by their height in meters squared. To be classified as obese a person’s BMI will be equal to or over 30. (CDC, 2015)
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).
In order to identify a condition as a disease, it should fit certain criteria. One of the reasons that obesity is classified as a disease is because of its large comorbidity. Obesity is a risk factor for chronic diseases such as hypertension, dyslipidaemia, type 2 diabetes, cardiovascular disease, sleep apnoea, musculoskeletal disorders and some cancers (Rossner, 2002). According to Rossner (2002), the death rate from all causes, cardiovascular disease, cancer and other diseases increases among moderate and severe overweight men and women in all age groups. Therefore, obesity is
Obesity is defined as defined as abnormal or excessive fat accumulation that may impair health. Obesity is not only based on an individual’s weight but also their BMI. A BMI greater than or equal to 25 is overweight. A BMI greater than or equal to 30 is obesity ((Organization, 2013). Obesity is the most common preventable deaths and the fifths leading health risk globally. Obesity has also been linked to other debilitating diseases and can increase a person’s chances of being hospitalized. Obesity-related conditions include heart disease, stroke, type 2 diabetes and certain types of cancer, some of the leading causes of preventable death (cdc.gov, 2014).
Obesity may be linked to differences in the microbial makeup of each individual. Individuals prone to obesity may possess microbes that are more efficient at extracting energy from food than lean individuals.
The dangers of the obesity epidemic are overwhelming and the percentage of the population which suffers from this condition is increasing exponentially with the increased use of HFCS. Especially in the United States, where almost a third of the adult population is obese, the problems with obesity are readily becoming more apparent. Researchers predict that about 30 serious medical conditions can arise due to obesity. Some of these complications are type II diabetes, high blood pressure, coronary heart disease, and arthritis. Problems can also extend to hypertension, birth defects, increased chances of various cancers, and impaired mobility.
Obesity is defined as having excess body fat. To be considered obese, you must have a BMI of 30 or higher. Your BMI, Body Mass Index, is a measure of body fat based on height and weight. While obesity can affect all ages, sexes and ethnic groups, compared with whites, African-Americans have 51% higher and Hispanics have 21% higher obesity rates (CDC, 2010). Along with that, it has been found that women with higher education are less likely to be obese compared to those with less education (Rodrigo, 2013). Also, obesity is affecting younger ages each year; childhood obesity has more than doubled in children and quadrupled in adolescents in the past 30 years. It is said that one-in-three children are affected by excess body weight, which then carries into adulthood. According to the AACAP (American Academy of Child and Adolescent Psychiatry), if one parent is obese, there is a 50% chance their child will be obese and if both parents are obese their child has an 80% chance of being obese.
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,
One of the biggest health concern in the united states today is obesity. It has been proven that approximately 36 percent of adults and 17 percent of children and adolescents are obese. Obesity is defined as the condition of being grossly fat or overweight. Obesity can also be represented as “BMI” which simply means body mass index. Most people will pay little or no attention to obesity, but obesity is a dangerous health issue that can result in death. Some of the factors that contribute to obesity are overeating, diseases, drugs and lack of exercise. Behaviors can also be a contributing factor to obesity. Behaviour such as physical activity and dietary patterns.
Body Mass Index (BMI) is a measurement tool used to determine excess body weight. Overweight is defined as a BMI of 25 or more, obesity is 30 or more, and severe obesity is 40 or more. Overall the problem stems from the general citizens lack of work ethic; in recent years that ethic has declined severely. It is the inability or flat out unwillingness to work and/or struggle to get what you want. The table below highlights the increasing obesity problem.
These include obesity, diabetes, and several heart conditions. Obesity is the term used for someone who qualifies as significantly overweight. A BMI (Body Mass Index) records weight in relation to height. A BMI of 25 is overweight and a BMI of 30 is obese. Obesity is not a disease in its self but it can lead to different health issues, some fatal. Obesity can be related to eighty percent of type two diabetes, seventy percent of cardiovascular disease, thirty percent to gall bladder surgeries, and forty two percent to breast and colon cancer. Unfortunately, obesity rates in people are rising rapidly. The United States alone had an obesity rate of twenty six percent in 2007. Some cases of obesity are gene related, but most other cases are a result of improper dieting and exercise among the individual ("Why Is Proper Nutrition Important?", Case Western Reserve University).
