At the start of the year Islay Mcleod was 29 kilograms heavier and suffered from migraines, nerve pain and a lack of energy.
Now, all those problems have gone and when the Whangarei woman catches a glimpse of her reflection, she feels proud.
The 29-year-old weighed 118kg when she joined Weight Watchers in January. Now she weighs 89kg and has won the Weight Watchers "Healthie" award for Inspirational Story.
"When I catch my own reflection, I feel proud. But I think the energy I have for my life is completely different. You get a feeling of self empowerment and belief - if I can lose 29kg what other goals can I put my mind to and achieve?"
At 19 Ms Mcleod was diagnosed with Crohn's disease - a chronic inflammatory disease of the intestines. She said a combination of the medication she was on and how she felt caused her to gain weight. Then, at 28, she was diagnosed with coeliac disease - an autoimmune disorder that causes a reaction to gluten. Before losing weight she suffered from a lot of health issues.
