The extreme weight loss of actors is drawing attention once again. Recently, Kim Ji-won's noticeably thin figure became a hot topic online after her appearance at a global jewelry event was revealed.

On the 24th, Kim Ji-won appeared at the event alongside Hollywood actress Anne Hathaway and Chinese actor Yu Yibai in a video released through Vogue Hong Kong's official channel. At the event, Kim Ji-won's clear collarbones and slender shoulder line stood out in a tight dress, prompting various reactions from netizens. Some expressed concerns about health, saying things like "It looks unnatural," "Her face is too gaunt and lacks vitality," "This body type doesn't suit being extremely thin," and "I'm worried about her health." Meanwhile, others criticized the styling, commenting, "The dress choice is disappointing," and "The hair and makeup seem off."

There is also speculation that Kim Ji-won's body transformation is related to preparing for her next project. She is set to play the role of genius surgeon Gye Soo-jung, a strong dark hero, in the upcoming drama Doctor X. Previously, during the filming of The Queen of Tears, she also showed self-management for her character by cutting out Chinese food for a year.

This phenomenon is appearing in many actors besides Kim Ji-won. Park Min-young revealed that she lost weight down to 37 kg for her role as a terminally ill patient in Marry Me, My Husband, explaining, "If I gained weight, I didn't think it would suit the character," and said she drank 3 liters of water daily during filming. She added that she returned to her normal routine after filming ended. Ha Ji-won, in her drama comeback after four years with Climax, shed her healthy image by reducing muscle through weight training and making her body lines look longer and more delicate through stretching. She said, "The process of erasing myself was harder than acting." In addition, many actors such as Go Hyun-jung and Ahn Eun-jin are enduring weight loss for their roles.

Recently in the entertainment industry, so-called "bone-thin" body transformations have continued, raising concerns about health among fans. Actors' weight loss and character immersion processes for their upcoming projects are ongoing.
