New Zealand paramedic student Riley Hemson describes herself as "just a huge girl trying to get some abs" on her Instagram page.
The 21-year-old's starting weight was 114kg and she has lost 25kg in a year. She hopes to reach her goal of 70kg by the end of her weight loss journey.
With almost 24,000 supporters on social media cheering her on, Hemson regularly posts "Transformation Tuesday" photos to show her incredible progression.
"My weight loss journey stopped and started many times. I was overweight as a child and I can't remember ever not worrying about my weight," she told Daily Mail Australia.
