Boxer David Letele, aka Brown Buttabean, has started a website to help motivate people on their weight-loss journey.
The website was only launched last week and has already had huge interest with over 3000 followers.
In a year he has lost a total of 75kg.
"The pressure steams from being overweight and Māori and Pacific Islanders represent a large category of the obesity in NZ," Letele says.
Now he wants to share his story to help others on their journey to a healthy life.
He adds, "I was over 200kg so I couldn't do a lot of stuff and I was embarrassed to go to the gym at first."
At the time, he was ashamed of his weight. He believes, "Losing weight, one guy has lost five kilos since he has started on Saturday."
After some hard work, he has managed to turn his life around.
Letele says his website isn't only for Māori and Pacific Island, but for everyone.
