Mr. Kim, the principal of the institute, launched a special project titled 'Healthy and Joyful School Program' after Jeju Central Girls' High School ranked highest in obesity rate of all girls' high schools in Jeju Island.

To lose the title of being the heaviest school, Jeju Central Girls' High School changed its meal plan to the '2+2' plan, where 2 types of fruit and 2 types of vegetables are available for lunch each day. In addition, an aerobic class is available where students can learn the dance moves to hit K-Pop songs such as TWICE's ''Knock Knock". A new rule prohibiting fast food and snacks in classrooms will also start taking effect in April.

A freshmen student Kim Ji Eun shared a comment about the school's fight against obesity, and said, "It's fun learning new moves every day. I can feel that our school has become healthier as we take aerobic classes and exercise."

A sophomore student Lee Soo Ji commented, "It was annoying at first because our lunch time was cut short and we couldn't eat anything other than school lunch, but I started enjoying exercising and felt the fun. I'm now joyfully participating in the program after seeing weight loss results."
