Am I obese? | At home obesity diagnosis and BMI calculator

11 September, 2018
Am I obese? | At home obesity diagnosis and BMI calculator

A weighty issue

The latest stats (2014-15) on the state of obesity and weight in Australia are alarming:

  • 2/3rds of adults are overweight or obese
  • 28% of adults are obese
  • 1/4th of school-age children are obese
  • 22,700 weight loss surgeries occurred

Even more worryingly, obese people may not be aware or in denial of their obesity.

In a UK study that took place over five years, it was found that an average of 10% of obese adults acknowledged their condition.  Tellingly, those who were aware of BMI were more likely to recognise whether they were obese.

What is obesity and what are the health risks?

Obesity refers to weight and volume of fat.

Health risks associated with obesity are:

  • Muscular-skeletal issues (from weight-bearing)
  • Fatty liver
  • Stroke
  • Depression and anxiety
  • Heart disease
  • Dementia
  • Cancer
  • Hypertension (high blood pressure)
  • Sleeping difficulties
  • Breathing difficulties
  • Kidney disease
  • Pregnancy issues
  • Type 2 diabetes

How do we measure obesity?

There are two main methods to measure obesity:

BMI score

BMI (Body Mass Index) is a score that derived by dividing your weight by your height in meters squared.

18.5-24.9 is the optimal, healthy weight range

25-29.9 is considered overweight

30+ obese

40+ morbidly obese

Waist measurement

Measuring waist sizes can give an indication of how likely people are to be affected by obesity related chronic illnesses.

For men – a measurement of 94cm

For women – a measurement of 80cm

One-size fits most but not all

Different body shapes, heights, and muscle mass can make these measurements inaccurate. For example, a professional athlete may have enough muscle mass to be pushed into an obese rating.

If you’re a regular Joe or Joanna, both measurements are reliable indicators as to the state of your weight health.

How to check if you’re obese

BMI calculator

Before you type your details into the calculator below, here’s how you can get the most accurate results.

Measuring your height – get a friend and a tape measure. Make sure you’re standing up straight, eyes level, shoulders back, chest out. Keep your feet flat, feeling the weight in your heels. Try not to sway.

Measuring your weight – your weight fluctuates during the day due to water loss and retention, drinking and food consumption. Measure three times during the day – morning, noon and night – and average out the results.

Once you’ve done that, have a go with our BMI calculator:

Waist measurement

To measure your waist, first find the midway point between the top of your hip bone and your bottom rib.

Again, get a friend, but try using cloth or linen tape measure.

You can move your arms to make space but try not to lift them too high or throw off your posture.

What do my results mean?

Underweight - BMI <18

Being underweight is associated with health problems like:

  • Weakened immune system
  • Respiratory and digestive diseases
  • Certain types of cancer
  • Osteoporosis

To gain healthy weight, you should start eating regular, nutrient rich meals, and increasing health fat intake.

Healthy weight - BMI >18 25<

Congratulations! A healthy weight is key in reducing cancer risk, relieving and preventing depression and depressive symptoms, reduces stress, leads to better sleep, and much more.

It’s time to start thinking about your next health goal, whether it’s drinking more water during the day, taking on meditation, exercising more, or visiting health practitioners on a regular basis.

Overweight - >25 30< Obese - BMI > 30+

Being overweight or obese is reversible - here are the first steps to take:

Visit your GP – your local health practitioner will be able to diagnose your condition and test for other chronic conditions. They might prescribe medication for any associated conditions.

Change your eating habits – start eating more fruit and veggies and less empty calories. If you’re thinking about taking on a fad diet, consult with your GP first before undertaking it.

Remember, all fad diets have the same basic principles: consume less calories, eat healthier foods.

Start regular exercise – anything from walking to yoga to the gym is a good step. Exercise burns calories during and after the activity and can also improve aspects of mental health that may be contributing to your obesity.

What Our Members Think

I joined as a CBHS member in 1978. Through many health events and challenges CBHS has always been there for me and my family. Their exceptional service over this time has always been appreciated.

What Our Members Think

I've not long joined CBHS from another fund, but so far I've been impressed by the super helpful and friendly staff, the higher claim limits and rebates at a very competitive premium, and how easy it is to lodge manual claims through the app. Thanks CBHS - you've won me over! 😃

- Rachel N

What Our Members Think

I have been with CBHS since I began at CBA 15 years ago...Now I have three beautiful children, one who has a disability. Our top extras cover has been really essential for his early intervention. I do love the ease of claiming online.

- Annette E

What Our Members Think

I am relatively new to CBHS and am loving it already. I worked for a CBA subsidiary a long time ago but was still eligible to join. So much better that the for-profit funds - our premium is only a little more and we pay a lower co-contribution and get great benefits. I am loving the massage rebate for my partner and gym rebate for me!

- David G

What Our Members Think

I'm extremely happy with CBHS! I have been a customer for about six years. I think the price is reasonable. And i would refer you to my family and friends any day. Thank you CBHS!!!

- Karen W

What Our Members Think

Love CBHS as I never have to doubt that they've got my back when I need it. Been through other insurers who have limited options or limits, yet cost the same or more.
