Bird was able to shed weight by following a simple, clean-eating dieting plan, combined with hard work and persistence after a sudden life re-evaluation.
The hospitality trainer and chef turned personal trainer has now not only transformed his body, but also has a new lease on life.
Bird, a father of one from Rockhampton, said he used to get frustrated in the past with his body image.
Following the 123Diet he was able to bring his weight down from 128kg to 87kg and get rid of the excess kilos he gained from his medical treatment early last year.
The 123Diet combines diet drops with a low-calorie eating plan for fast weight reduction in a 42-day programme.
"One night, I came across the 123Diet programme and it's online community through my Facebook newsfeed," he said.
"I would frequently read other people's stories, learning what they did and how it had affected them and changed their perspective completely after finishing the programme.
"I had watched and followed the site rather sceptically for six weeks until I mustered up the confidence to give the product a go.
"You don't always have to be where you are or stuck in a never-ending rut.
"You can change and you can overcome anything you set yourself to … but only if you're determined to make that change."
Bird said staying focused and ultimately keeping his eyes on the prize helped him to achieve his weight-loss goals.
"Over my journey so far, there have be ups and downs," he said.
"There have been times where I wanted to stop due to whatever the reason was, but I knew I didn't want to be the person I had been for the past 46 years.
"I vowed to myself that I was not going to live the next 42 the same way.
"I realised at such a later time in my life, but it's advice that I pass on to everyone else now - it's your time, it's your life, please make it count. Don't be afraid to create the new, happier you."
