What is your real ‘biological age’, and what does this mean for your health?

What is your real ‘biological age’, and what does this mean for your health?

When it comes time for treatment, our options are strongly influenced by our age - or perhaps our relative level of fitness compared to others our age, rather than how many years we've lived, as this has a strong determining influence on whether we would do better on BR rather than FCR, for example. So it was with some interest I read this article by Carissa Bonner, Research Fellow, University of Sydney:

Of particular relevance: "There is some research to suggest “biological age” formats like heart age have more emotional impact and may act as a wake-up call to motivate people like Richard to change their lifestyle and reduce their risk factors – which is a good thing.

But they can also mislead people by making them worry that their risk of disease is higher than it actually is. As such, they shouldn’t be used to make decisions about preventive medication, such as whether to take drugs to lower cholesterol levels or blood pressure.

If you get an older “biological age” on any of these calculators, don’t get too worried about the exact number – it’s not a direct measure of ageing or life expectancy."

Importantly, like receiving a diagnosis of CLL, these biological age calculators do provide a wake up call for people to reassess what they can do to improve their health through lifestyle changes.

I saw that programme where 'Richard' was said to have a biological age of 92 at age 49. He was extremely obese and did lose weight but given the biological ages he was given I was immediately sceptical about the method of calculation.

Still, it makes you think and definitely has more impact. Perhaps it should be used more in midlife people whilst it's not too late to change.


When over 65 and with a disease that requires one to eat well, losing weight and exercising should be on the list also. In June 2017 I finally hit the 150 mark and said to myself, 'that's it', I've had it with being overweight. So, I went on a fish and chicken diet incorporating vegetables and eliminating as many carbs as I could. I have now begun to eat some red meat, but keep that to a minimum. I have a gym in my neighborhood and I began walking the treadmill. Slowly, my weight went down and over a five month period I lost 17 pounds. I do want to say, don't lose any unwanted weight too quickly.
