Carla Thomas has long been a healthy eater but her sweet tooth bothered her.
The 27-year-old, of Melville, decided last year to cut out all sugars - natural and added - from her diet for a few weeks.
Since then the holistic counsellor has reintroduced a limited amount of fruit into her diet and believes her low-sugar living has improved her body and mind.
"I'd always had a sweet tooth," Ms Thomas said yesterday. "I justified it because I was reaching for things that were healthier - it wasn't a chocolate or a lolly. I probably added too much natural sweeteners on to things."
Ms Thomas did the eight-week I Quit Sugar program, which has become a bestselling book by Sarah Wilson and which has attracted criticism from nutritionists.
"When I did it, I started to notice my palate changing," she said. "For someone who's relatively healthy, you really don't realise how much you're consuming every day in everything."
Apart from skin breakouts in the first few days of quitting sugar, Ms Thomas found she had more energy and her concentration and mood improved.
Though cutting out fruit for a few weeks as part of the program was hard, Ms Thomas said it was necessary to cleanse the body of fructose.
