Actress Kim Min Ha's further weight loss has drawn attention as she was seen alarmingly gaunt.
Known for her roles in 'Pachinko,' 'Light Shop,' and 'Typhoon Family,' Kim Min Ha has been recognized for her unique aura and beauty, unconventional in the Korean entertainment industry. However, she has shed the look, undergoing dramatic weight loss for her role in the upcoming romance film 'Viva La Vida,' which is based on a true story.
In recent videos and photos uploaded to Instagram, Kim Min Ha appeared with startlingly thin arms and sharply protruding shoulders. The images showed a drastically slimmer frame, a stark contrast to the healthy and toned appearance she had displayed in the past. In the video, Kim wore a white sleeveless top while staring into the camera, with her visible bone structure, slimmer jawline, and hollowed cheeks highlighting the severity of her transformation. In another photo, she was seen holding a plush doll.
Kim Min Ha’s sudden physical transformation is tied to the storyline of the film. In the movie, she plays a terminally ill patient who has been given only a short time to live, and she reportedly lost more than 10 kilograms to fully embody the role. She had previously revealed in an interview after the tvN drama 'Typhoon Family' ended last year that she had also lost 9 kgs (19.8 lbs) for that project, leading to speculation that she has continued to slim down since then. Kim is expected to remain active in the coming months. Her film 'Hana Korea' is set to open next month, and she has also been confirmed for the Netflix drama 'Dead-End Job' and the Disney+ series 'The Miracles of the Namiya General Store.'
As interest grows around Kim Min Ha’s transformation, attention has also turned to South Korea’s rapidly spreading “bone-skinny” trend, particularly among younger generations. The term does not simply refer to being slim. Instead, it describes an extreme body ideal in which a person is considered attractive only when their bones are visibly pronounced.
The trend has been spreading quickly among teenagers and people in their 20s. Those who follow it often define the “ideal body” as one in which the difference between a person’s height and weight is at least 120 to 125. For example, someone who is 165 cm tall would aim to weigh 40 to 45 kilograms or less (88lbs to 99lbs).
The “bone-skinny” phenomenon is also closely linked to pro-ana culture, online communities that romanticize anorexia and extreme weight loss. In those spaces, starvation and dangerous dieting behaviors are framed not as health crises but as admirable goals, with users encouraging one another to continue.
One of the most serious consequences of the trend is the rise in eating disorders. Extreme food restriction, repeated bingeing and purging, and the abuse of laxatives and diuretics are increasingly spreading like a social fad. The number of eating disorder patients in South Korea has risen sharply in recent years, turning the issue into a serious medical concern rather than a simple matter of appearance management.
Severe malnutrition can leave irreversible damage throughout the body. Hormonal imbalances can cause irregular periods or the loss of menstruation altogether, while declining bone density can worsen osteoporosis. Anemia and hair loss are also common side effects. For adolescents, whose bodies are still developing, nutritional deficiency during these formative years can lead to lifelong developmental problems and weakened immune systems.
Anorexia is known to have one of the highest mortality rates among psychiatric illnesses. Cardiac arrest caused by severe malnutrition, organ failure, and acute complications stemming from electrolyte imbalance can all become life-threatening. At the same time, the illegal distribution and misuse of appetite suppressants, commonly nicknamed “butterfly pills,” is also growing. Teenagers and young adults who take such drugs without a prescription often experience insomnia, severe heart palpitations, hallucinations, depression, and other neuropsychiatric side effects. Some even develop symptoms of addiction.
Another deeply concerning aspect of the “bone-skinny” trend is body dysmorphic disorder. Even when a person is objectively so thin that their bones are clearly visible, they may still look in the mirror and perceive themselves as “fat.” This distorted body image reflects a breakdown in the way the brain and cognitive system process signals, and it is notoriously difficult to treat.
That distortion often leads to obsessive behavior and depression. Participants may tie their self-worth to a change of just a few hundred grams on the scale, causing extreme anxiety, compulsive behavior, social withdrawal, and depressive symptoms. In that sense, the pursuit of a “bone-skinny” body can become a vicious cycle that steadily erodes mental health.
The trend has been accelerated by social media. Short-form platforms such as TikTok, Instagram, and YouTube Shorts are flooded with challenges such as “cover your waist with an A4 sheet of paper,” “wrap your waist with earphone cords,” and “legging leg checks.” These trends essentially turn extremely thin bodies into a form of performance and public judgment, generating millions of views and shares. Algorithms then push the content to even more users, accelerating its spread.
Peer pressure also plays a major role. Teenagers, who are especially sensitive to media influence and social acceptance, may join these communities to avoid being left out or because they are persuaded by the distorted belief that “people are kinder and pay more attention if you’re pretty.” Within schools, cram academies, and online communities, extreme dieting is often glamorized as proof of discipline and praised as a sign of strong will.
Even more troubling is the fact that some medical institutions are accused of exploiting the trend. Plastic surgery clinics, dermatology offices, and weight-loss centers have aggressively promoted procedures and prescriptions using buzzwords such as “bone-skinny,” “bony arms,” and “bony hips.” Liposuction, radiofrequency procedures, and diet medications are marketed by tapping directly into public anxiety about appearance and effectively encouraging a pathological trend.
At the same time, South Korea’s appearance-driven culture has distorted the very meaning of “self-care.” People who are average weight or slightly heavier are often stigmatized as lazy or lacking discipline. Meanwhile, extreme starvation and physical self-damage are paradoxically praised as evidence of willpower and strict self-management. Beauty standards have also become increasingly narrow, with the physiques of K-pop idols and influencers treated as the absolute benchmark of attractiveness, leaving less room for body diversity and healthier standards of beauty.
Kim Min Ha’s case should be understood in the context of artistic preparation for film and television. Actors often transform their bodies to better convey a character’s emotional state and circumstances. However, when those transformations are shared publicly on social media, they can create the dangerous impression that extreme weight loss is something glamorous or achievable. This is especially risky for younger fans, who may try to imitate the physical changes of celebrities they admire without understanding the context behind them.
Experts stress that the “bone-skinny” trend should not be dismissed as a beauty fad or a matter of personal preference. Rather, it must be recognized as a growing public health issue tied to both physical and mental illness. The problem extends beyond individual choices about appearance and raises broader concerns about body diversity, social values, and mental well-being. Parents, teachers, medical professionals, and media platforms all share responsibility for addressing it.
