An 18-year-old Thai girl named Wanwisa Nanongtoom has managed to lose 44kg and clear her acne in just one year through sheer hard work and determination.

This was after being unkindly labeled as an "elephant" and "pig" by her school mates.

Wanwisa shared her journey in a Facebook album, which was subsequently picked up by various Taiwanese and Chinese media.

The then-98kg girl looked like this:

According to Taiwanese news site EBC, Wanwisa had undergone stressed-induced binging, which resulted in an acne condition and skyrocketing weight.

That was when her school mates gave her the nicknames.

And although she appeared to laugh it off, Wanwisa was actually hurt by the comments, EBC reported.

In her second year, Wanwisa decided to start her makeover journey.

She restricted herself to only two meals a day, and avoided carbs as well as sugary foods.

The student also increased her intake of plain water, and ate a banana when she got hungry between meals.

Regular exercise became part of the program.

As she slimmed down, Wanwisa started to learn more about make up and dolling herself up.

Here are more photos of her progress:

Definitely a laudable effort.
