Male celebrities in Korean entertainment are adopting high-profile weight-loss regimens ranging from marathon training and lifestyle overhauls to the use of obesity medications to redefine their public images.

While weight loss among female celebrities has long been a focal point in Korean entertainment media, recent trends show male celebrities as the focus of health management. Singer Shindong, comedian Kwak Bum and singer Sung Si-kyung are drawing attention for recent weight loss.

Shindong, a member of veteran K-pop boy band Super Junior, recently posted photos from a trip to Beijing.

"I really had fun in Beijing — eating delicious food, sightseeing, taking pictures and riding amusement park rides," he said.
