Two years ago, Sarah Wolter looked unrecognisable.
At 166 kilos, the South Australian working mum lived a life of no exercise while consuming a high-calorie diet of carbohydrates and sugar.
Ms Wolter, who is now an incredible 83kg lighter, told Channel 7's Sunrise on Wednesday that she was always conscious
of being "the big girl" and that her weight often held her back from doing certain activities in life.
After seeing a segment on the breakfast program several years earlier, Mrs Wolter decided to give the scientifically based CSIRO diet a try β and ditch the fads she'd attempted previously.
"Before the diet, I ate a lot of high-carb foods so bits of bread and butter," she told Channel 7. "One of my worst habits was snacking between meals. Lots of chips and crackers and cheese and that sort of thing."
