Overweight and obesity in Australia is reaching epidemic proportions.
We are now one of the fattest nations in the developed world with the prevalence of obesity more than doubling in the last 20 years.[1]
The most recent statistics from Obesity Australia indicate that 63 per cent of our country is overweight or obese, with 28 per cent obese. According to their 2014 report, No Time to Weight, obesity is a major health and societal factor for the Australian population. [2]
Unfortunately, things are likely to get worse with projections seeing around 70% of Australians being overweight or obese, by 2025, with around a third of the Australian adult population falling into the obese category.
Personal cost
It is well documented that carrying too much weight is dangerous for your health. While obesity is not a disease, it does contribute to the development of other diseases. [3]
Health problems and consequences of being overweight include:
cardiovascular disease such as hypertension (high blood pressure)
coronary artery disease and stroke
obstructive sleep apnoea
insulin resistance and type 2 diabetes
non-alcoholic fatty liver disease
cancer
osteoarthritis
cognitive impairment
mood and anxiety disorders, including depression, negative body image and poor self-esteem.
If the thought of developing the above diseases isn’t enough to shock you, what about dying early?
Obesity Australia states that 40-year old obese women who don’t smoke will lose around 7.1 years of life, while obese male non-smokers will die 5.8 years earlier than expected. This is compared with their normal weight counterparts. [4]
The financial cost
As well as costing people years and quality of life, obesity is costing our country billions every year.
Estimating the financial cost of obesity is complicated. However, 2008 figures from Obesity Australia puts Australia’s total obesity cost at $58.2 billion per year. [5]
Costs relating to obesity include loss of productivity, carer’s costs, health system costs, and wellbeing. The total financial and lost wellbeing costs broken down by obesity-related diseases are as follows:
Cardiovascular disease
Financial cost $2.8 billion
Lost wellbeing $31.8 billion
TOTAL $34.6 billion
Cancer
Financial cost $695 million
Lost wellbeing $9.0 billion
TOTAL $9.7 billion
Type 2 Diabetes
Financial cost $3.0 billion
Lost wellbeing $5.3
TOTAL $8.3 billion
Osteoarthritis
Financial cost$1.8 billion
Lost wellbeing $3.8 billion
TOTAL $5.7 billion
That’s an awful lot of money to spend on disease!
The future
There is no doubt Australia is at a crossroads.
If the rate of obesity continues to grow at the projected rate, it’s fair to say the financial and wellbeing costs will also grow — to overwhelming proportions.
However, by taking steps to lose the excess fat, improve health and wellbeing, we as a nation can turn the statistics around. Not only can we save billions of dollars, we can improve our quality of life, and our life expectancy.
If you feel you need to take control of your weight and health, speak to your health care practitioners and consider joining your local fitness studio and/or take some personal training sessions.
We all know that exercise is an integral part of being healthy, right?
However, what you may not realise, is that exercise is good for the mind as well.
How exercise affects the brain
Numerous studies have proven the benefits of physical exercise on brain function. For example:
• exercising for just 20 minutes, facilitates information processing and memory functions • cardiovascular exercise can create new brain cells (known as neurogenesis) and improve overall brain performance. • exercising regularly into old age may better protect against brain shrinkage (and more ‘senior moments’), than mental or social activities • exercise increases levels of brain-derived proteins (known as BDNF) which are believed to help with decision making, higher thinking and learning. (Physiology Behaviour) • regular exercise increases memory and the ability to learn new things • people who exercise on a regular basis are more productive than those who do not engage in regular activity • creativity levels are boosted for up to two hours, following an aerobic workout. while walking can boost creativity by up to 60 per cent • regular aerobic exercise changes the brain to improve memory and thinking skills (British 2)
Why is exercise so beneficial?
According to Harvard University, exercise is beneficial because it helps reduce insulin resistance and inflammation. It also stimulates the release of growth factors, which protect the health of existing brain cells and assist in the growth of new blood vessels and cells in the brain.
Harvard says that exercise’s ability to improve mood, sleep, stress and anxiety, also has a direct impact upon cognitive function, as problems in these areas have a negative effect on brain function.
Brain HQ adds that different exercises may have different impacts upon the brain. For example, ballroom dancing has a higher impact upon cognitive functioning that some other exercises, because it combines physical and mental demands.
What does it all mean?
Exercise seems to benefit both the body and the mind.
Breaking up your day with some exercise can make it easier for you to concentrate on tasks and be more productive throughout your day. It can also help you problem solve and relieve stress and tension. Being active each day will also mean you are less likely to suffer from a mid-afternoon slump, which often leads to unhealthy food choices.
Tips to exercise while at work
Many people cite lack of time as an excuse not to exercise. However, there are always ways to include activity in your working day. For example:
• commit to a regular exercise class (either before or after work, or even at lunchtime) • go for a walk at lunchtime — you may even wish to start up a walking group • use the stairs where possible • if you commute, get off a stop early and walk the remaining distance (where practical) • cycle or walk to work • take regular breaks from your workstation, even if it is just to use the bathroom • incorporate more movement into your day (e.g. physically get up to talk to a colleague instead of emailing them) • stretch regularly • walk about the office while you are on the phone • walk to the coffee shop for your morning coffee • offer to run errands.
How can employers encourage exercise in the workplace?
If you are an employer, remember those who exercise regularly are more productive, energetic, creative, think better and learn quicker. They are less likely to be stressed or anxious and are likely to take fewer sick days.
So in the interests of work output, and a happier and healthier workplace, why not:
• encourage workers to get up from their desks and move around • ensure workers take a lunchbreak and go for a stroll • set up ‘walking meetings’ rather than ‘coffee meetings’ • offer financial incentives (e.g. salary packaging) for exercise classes or gym memberships • sign up company teams to various events such as fun-runs, charity walks or triathlons • organise a company discount for local facilities such as golf-courses, tennis clubs or gyms • take advantage or outdoor activities for team-building days • incorporate physical activities as part of corporate conferences • allow greater flexibility in the workplace for employees wishing to exercise before or after work • install ‘active desks’ for staff.
While it may take more effort and creativity to increase your exercise levels, the benefits are well worth it. As well as improving your capacity for creativity and sharp thinking, you are also likely to improve your job performance and your career prospects.
