Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have a negative effect on health, leading to reduced life expectancy and increased health problem. Recently, obesity has become a trend worldwide and a new word globesity is derived from global and obesity. The ABC NEWS says there will be 1 billion obese people by 2030. Although the causes behind the obesity vary from nation to nation, there are still some general causes they share in common. The causes can be sorted into three categories: genetics, sedentary lifestyle, and diet, which have a huge impact on the individual health and economic development of a country.
Cause and Effect
The primary cause of obesity lies in the genetics. Children may inherit FTO gene (fat mass and obesity associated) from their parents. According to Kolata, Gina (2007), 80% children who have obese parents are obese and less than 10% of offspring who have normal weight parents are obese. A popular hypothesis about genetics is thrifty gene hypothesis, which is put forward by geneticist James V. Neel in 1962 and has been controversial since then. Neel thinks that in the Old Stone Age, pregnant women try to accumulate fat to survive from the potential famine, but as time goes by, people do not need exceed fat to register hunger in the modern society. However, they don’t have an effective way to spend the redundant energy, which causes the spread of obesity epidemic.
The second cause of obesity is due to sedentary lifestyle. The excellent transportation makes it possible to save time and energy from one place to another destination, which means people have less time on exercising. The invention of computers, smart phones and other electronic products catch people’s attention. It is usual for people to spend over eight hours on the computers in the workplace and spend the rest time with their personal computers and cell phones when finishing their work. As a result, fat accumulation is hard to unavoidable. More obese people become, lazier they become. It is like a vicious circle.
The last cause of obesity is because of the unhealthy diet. The fast paced society requires people to save time from their busy schedule, so the working class tends to choose fast food and milk for daily meals, and the busy parents prefer to prepare bread and milk for their children. However, the milk products are filled with high sugar where the products even have been labeled with no sugar. It is not abnormal for that the sugar company wants to earn money from the milk through this way. A great whoop and holler of fast food has made it become a new trend for the in people. People have less chance to eat vegetables and fruits and some children even cannot recognize the correct vegetables. Another situation is that people used to eat little when they decide to keep fit and restart to eat and drink too much to treat themselves, which actually makes no sense and gain weight.
These three causes should be responsible of individual’s health and the loss of national economy. The effect on the people’s health appeals in the lifespan. University of Oxford does a research about the relationship between obesity and life expectancy. Epidemiologist Dr Gary Whitlock explains that overweight could cut down human lifespan. In some developed countries such as Britain and America, people who are overweight a third than the normal standard shorten life expectancy by about 3 years. Because a third more than the normal standard means the obese people must carry 20 to 30 kilograms [50 to 60 pounds, or 4 stone] of excess weight no matter where they go. Beyond that, obesity could result in many common diseases, including coronary heart disease, high blood pressure, type 2 diabetes, stroke, abnormal blood fat, metabolic syndrome and cancer. A statistics from American National Center for Health Statistics shows that obesity has caused 90,000 (88,000–94,000) deaths from cardiovascular diseases.
The effects of obesity not only lie in the personal health state, but also in the economic development of country. Government need to put a large part of financial budget into solving the obesity epidemic. They need to put much money on the public hygiene and medical care, establish physical infrastructure for citizens to exercise, shoot non-profitable promotion advertisement to attract people’s attention to this issue, and spend much money on teaching people healthy diet and lifestyle. All the efforts need financial support. More money they put into, less money they use in the development of economy and more money people must pay. According to Jamie Oliver, obesity costs 10% of American medical care bills, namely 1500billion dollar a year, which is going to be doubled in 10 years.
In addition, the obesity epidemic is not subject to the old developed countries, but to transfer to the developing countries, such as China, India, and so on. It is indeed a catastrophe. It is sweeping the world and upgrades to a global issue. As Allen Gustafson says, obesity has become more and more serious as hunger. These two issues combine a crisis for the global development. Due to the more serious situation increasingly, the global food and other resources face a huge threat.
To sum up, the obesity epidemic is a consequence of genetics, sedentary lifestyle, and unhealthy diet. It has a huge impact not only on the individual health, but also on the economic development of a country. As currently envisaged the obesity epidemic has been sweeping the world and become more and more serious.
