He shed a massive 77kg and is now down to about 66kg.
He claims his weight loss wasn't a miracle, but rather the result of discipline.
In the video posted on his Facebook page, The Andy Journey, he said to succeed, losing weight had to be something you really wanted. He didn't struggle with his weight loss a lot, but he did have moments where he broke.

Andy started putting on weight in primary school but he was playing soccer and baseball and it didn't seem like it was an issue.
His mother Mary Albertson began to notice but she just thought he was a little heavy-set.
"He eventually dropped out of soccer, after two seasons of little league baseball he quit baseball and I think he began to feel like he couldn't keep up and compete with the other kids but we tried to encourage him to play but he just quit. I guess that's when I began to realise his weight was affecting his lifestyle," Ms Albertson said.
She had fears her son would become a 35-year-old man sitting in the basement of his parents' house playing video games and eating.
She choked back tears when she recalled one night when she was helping Andy with his homework and he said if he had one wish, he would want to be skinny.
"As a parent you see your child struggling with being overweight but the thing that seems to make them the happiest is food, so that's what you give them," Ms Albertson said.
Andy said in primary school he weighed about 115kg but put on another 30kg when he went to college.
"I was done being fat and done seeing the number on that scale go up and up," he said.
In January 2015 he began working out and in four months he lost the 30kg he put on at college.
He was running on the treadmill every day but he started to plateau and his mum thought that's when he would quit. But when she heard somebody talking about personal trainer Jerry Hughes, she enlisted his help.
"It's a tricky thing when you meet with someone and they're talking about losing a lot of weight. Truly obese people can have a lot of excuses and I don't mean that in a bad way, it's their coping mechanism," Mr Hughes said in the video.
While Andy's mum claimed the whole family was heavy-set, Mr Hughes said we were all about the same size when we were born.
Mr Hughes said it wasn't just about teaching Andy how to lift weights at the gym.

They would meet up outside of the gym and talk on the phone when Andy was struggling mentally and needed help to overcome thoughts.
"That's where his battle was won," Mr Hughes said.
"If you do not control your mind you will never conquer your body."
The trainer said obesity was like any problem, and if you're child was blind or couldn't speak, you would do everything you could to help them, and obesity should be treated in the same way.
Andy said as soon as school starts again, he is going to show up 10 minutes late.
"Everyone's going to look at me and I'm not going to have a care in the world if I have to sit at the front of the class," he said.
