To give you a bit of background, at the end of 2009, I was made redundant from a job that I really hated, but desperately needed. I had little in the way of assets and at 36 years of age, I did, however, have a wealth of life experience gained from varied careers and a realisation that I was getting too old for another false start.

Now was the time to finally pursue the career that I really wanted - the one I was going to be good at, but more importantly, the one that was going to make me happy.

So with a little encouragement from a couple of mates, I bit the bullet and submitted an application to The Australian Film Television and Radio School to study a Graduate Diploma in Radio Broadcasting. To my surprise I was accepted on the first attempt and the rest, as they say, is history.

Shortly after graduating I started working as the afternoons announcer for 2HC Coffs Harbour. I viewed this as a new beginning, a chance to make a fresh start and turn my life around in a new industry and in a new town.

The adjustment to life away from Sydney was difficult but I was doing a job that I loved and for the first time in my adult life I felt truly happy - with one exception... I wasn't happy about my weight.

I had always been overweight but now found myself in the worst physical condition of my life. It was at that point that I made the decision to finally get into shape. In April of 2010, I engaged the services of a personal trainer - Renee Atkins from Beachbodies Health Club - and embarked on a weight loss program. The goals that Renee helped me set were ambitious but necessary.

I needed to lose 100 kilograms, and the only way to do this was through diet and exercise. I train with Renee three to four times per week and try to exercise on my own at least three additional days.

No magic potions - no miraculous secret program. It's tough, but I'm really enjoying it. I've drastically changed my eating habits, albeit with the odd relapse, and so far I've lost 50 kilograms!
