The problems surrounding obesity
News and opinions about overweight reach us every day.
The global rise in obesity is seen as one of the significant problems humanity may face now and in the future.
Overweight is often associated with health issues.
Many of us have either tried to avoid gaining those extra kilos or even harder yet, getting rid of them.
There is an epidemic of overweight in developed countries.
The World Health Organisation defines obesity as a body mass above 30 kg/m2.
Obesity is an accumulation of excess body fat that hurts health.
In an OECD publication “Obesity Update 2012” the OECD concludes:
- In over half of OECD countries, at least one out of two people is now obese or overweight.
The OECD expects rates to rise further. In some nations, 2/3 of the people will be obese within the next ten years.
- Healthcare is 25% more expensive for an obese person compared to a person of normal weight in any given period.
- Obesity amounts to nearly 5 percent of total health expenditures in almost all OECD countries (5-10 % in the USA).
- Obese people earn up to 18% less than non-obese men and woman.
- A broad prevention policy would avoid, every year:
155.000 losses from chronic illnesses in Japan,
70.000 in England,
75.000 in Italy,
40.000 in Canada, and
55.000 in Mexico.
- Obesity does not make a distinction between sexes
- Even in young children, obesity is common.
For instance, nearly 25% of boys and girls in the UK are now labeled as overweight or obese.
Obesity & The WHO (World Health Organization)
The WHO describes overweight and obesity as excessive or unusual fat buildup that presents a hazard to health.
Obesity was once considered a predicament only in high-income nations.
Now overweight and obesity are, according to the World Health Organization, dramatically rising.
It rises exceptionally fast in urban environments in low- and middle-income countries.
The WHO has made several other interesting observations about Obesity:
- In 2008 over 1.4 billion adults were overweight, and more than 500 million obese.
- At least 2.8 million people die each year as a consequence of being obese or overweight.
- Worldwide, over 40 million preschool (also nursery school outside the USA) children were overweight in 2008
- Obesity in children is one of the most pressing public health tests of the 21st century.
- More deaths are globally associated with obesity and overweight than to underweight
- Worldwide, 23% of coronary artery disease condition and 7–41% of specific cancers can be attributed to obesity and overweight.
- A harmful increase in weight can be caused by:
- An increased intake of highly calorific meals, without a similar rise in physical activity.
- Decreased levels of physical exercise will furthermore result in a lack of energy balance and drive to weight gain
- Supportive communities are vital in shaping people’s decisions and preventing obesity
Eating a healthy menu can help stop obesity occurring!
It is possible for people to:
1) keep a weight that is healthy
2) limit total fat consumption and shift the intake away from unhealthy saturated fats to unsaturated fats
3) raise consumption of vegetables, fruits, pulses, nuts and whole grains
4) curb the use of salt and sugar.
Everybody should go for enough physical activity in all phases of their lives.
The risk of diabetes, cardiovascular disease, breast cancer and colon cancer will be reduced by:
– At least 30 minutes of routine or moderate-intensity physical activity on most days.
What is your BMI?
Obesity and BMI
Obesity is defined by BMI (body mass index).
Another method to define obesity is to look at the distribution of fat via the waist-hip proportion and cardiovascular risk factors.
Both the percentage of body fat and total body fat relate to BMI.
A worldwide health issues
Waistline and Obesity
BMI is used as a sign of obesity.
But someone’s waistline size can be a useful indicator of a potential health risk and obesity too.
Swedish researchers published a study in the British Medical Journal suggesting that people with a waistline of 100 centimeters (39.3 inches) or more face a higher risk of insulin resistance.
People who experience insulin resistance are also more likely to develop heart disease and diabetes.
Now we’ll take a closer look at the graph above.
The data in this image shows the total number of cases of obesity in the given statistical population at a given time in several developed countries.
The USA lead the way with countries like Mexico, Australia, Canada and the United Kingdom not far behind.
At present, around a quarter of these countries population is overweight.
Unfortunately, the obesity rates are rising in countries like Korea and Japan that are currently quite low.
The increase in overweight and obesity, as mentioned before, is a major public health concern.
So to put it, in other words, being obese matters because it increases your chances of dying.
Obesity is the consequence of a mismatch between calorie consumption and energy expenditure.
You get more calories in than you burn.
This eventually results in a net buildup of energy reserves in the body.
The fat stored in our bodies increases the size and shape of our bodies. Besides these visible outward changes, many other less noticeable changes occur inside our bodies.
Often these only become clear when they manifest as a disease.
Obesity is associated with cardiovascular diseases and some forms of cancer.
Diabetes, specifically type 2 diabetes, is a common and severe consequence of obesity and can result in loss of vision and loss of limbs.
Obesity is becoming a global problem.
Some might argue it is already!
Worldwide a large number of people are going to suffer or are already suffering from its negative health implications.
These implications can even lead to early death.
All the resulting health problems and cost implications are a matter of great concern.
The World Health Organisation reports in “Obesity and Overweight” Fact sheet N°311, Updated March 2013, that worldwide, obesity has doubled since 1980.
In particular, the increase in child obesity is alarming.
It is evident that say this leads to more suffering for those involved and to a higher health care bill.
More and more people now come to realize that obesity has become the worldwide health problem.
It’s time that action is taken to prevent obesity getting worse and worse.
Fascinating topics of study involve diving deeper into the causes of obesity and to prevention/cure for obesity.
Preventing obesity could prove beneficial to the economy as well.
What Causes Obesity
The bottom line is that we gain weight because we eat more calories than we use.
The most abundant source of calories is food, but sugary carbonated drinks and alcohol add up too.
The question why we eat more calories than we use is a difficult question to answer.
The intake of “fast” food, as the next video hints too, might also be one of the causes.
