Meet Jiashing from Taiwan.
5 years ago, when she was 19, she weighed 100kg and was mistaken for being 30.
She was also often being mistaken for being her sister's mother, reports Izismile.
She decided to change her life around and stopped eating junk food, candy and meat.
Jiashing stuck to a strict diet consisting only of fresh fruits and vegetables.
She currently weighs only 60kg.
However, her transformation caused other problems.
She had to change all her documents, as she was no longer recognizable.
Also, she got detained by cops once for a few hours, as they thought she was a teen who ran away from home.
She also gets stopped by the cops often when driving, as she looks to young to have a licence.
