And now at 13st 7lb sheâ€™s no longer shopping for shapeless size 30 outfits after fitting into a 10 for the first time.
Emma, 23, said: â€œThe change has been amazing, I donâ€™t recognise myself sometimes.
â€œI was shopping the other day and saw a one shoulder prom dresses I liked but they only had a size 10.
â€œI decided to try it on anyway and I couldnâ€™t believe it fitted me â€” I was dancing in the changing room.â€
Emma, of Elgin, used to scoff burgers, takeaways, fizzy drinks and crisps. Her high calorie diet meant she was â€œmortifiedâ€ aged 17 when she couldnâ€™t fit on a theme park ride.
But now she makes healthy home-cooked meals and her favourite treats are low-fat yoghurt and fruit. She said: â€œI feel brilliant â€” Iâ€™ve lost the equivalent of a whole person.
â€œIâ€™ve got so much more energy when Iâ€™m out walking my dogs.
â€œIâ€™ve been overweight since a child, so it was the result of a lifetime of bad eating habits.â€
Emma, a class manager at Scottish Slimmers who started her healthy eating plan two years ago, added: â€œI donâ€™t see it as a diet â€” itâ€™s a complete lifestyle change.â€
