The pursuit of an “ideal” physique has long been a cornerstone of the global entertainment industry, but the standards are shifting toward increasingly extreme territories. In South Korea, a trend known as the “skinny to the bone” look has gained traction, pushing beauty standards beyond traditional slimness toward a state of extreme fragility. However, actress Lee Yu Bi is using her platform to challenge these narratives, revealing the psychological and physical toll of adhering to unrealistic weight expectations.
In a recent series of candid reflections shared via her YouTube channel, Lee Yu Bi opened up about the disconnect between her actual physical health and the perceptions of those around her. Her experience highlights a systemic issue within the industry where facial aesthetics—specifically the presence of bloating—are often misidentified as a need for overall weight loss, regardless of a person’s actual body mass index (BMI) or health status.
For many, Lee Yu Bi’s story serves as a cautionary tale about the dangers of external validation. By detailing her struggle with weight pressure while already weighing as little as 42kg, she exposes the irrationality of certain beauty standards and advocates for a holistic approach to wellness that prioritizes circulation, sleep, and mental health over a number on a scale.
The Paradox of Pressure: Weight Loss at 42kg
During a video titled “Taking a Break from Daily Life, in Bali. All-Inclusive Resort Vlog,” released on May 11, Lee Yu Bi recounted a distressing period from her twenties. Despite maintaining a weight of approximately 42kg, she was told by others that she needed to lose more weight because her face appeared “too round.”
This specific pressure—the demand to lose weight when already significantly underweight—creates a dangerous psychological loop. Lee Yu Bi recalled, “Someone once told me, ‘Yu Bi, you need to lose some weight, your face looks too round.’” This comment led to increased stress and a preoccupation with her appearance on screen, which she noted became a habit that persisted for years.
The absurdity of this pressure was highlighted when the reality of her physique became apparent to her colleagues. Lee Yu Bi shared that after being told to lose weight, she had a scene the following day that required her to remove her clothing. Upon seeing her arms, a staff member reportedly apologized to her and urged her not to lose any more weight. This moment underscored a critical discrepancy: while her face was perceived as “round,” her actual body composition was already at a precarious limit.
Distinguishing Between Fat and Facial Bloating
From a medical perspective, the confusion between facial bloating and body fat is a common misconception that can lead to disordered eating habits. As a physician, I have seen how patients often conflate edema (swelling) with adipose tissue (fat), leading them to pursue restrictive diets that do not address the root cause of the swelling.

Lee Yu Bi’s experience mirrors this clinical reality. She explained that she was highly sensitive to facial bloating, which she initially believed was a weight issue. However, as she entered her thirties and began incorporating regular exercise into her routine, she discovered that the swelling began to subside. She noted, “It turns out it was not about fat, but circulation issues.”
Facial bloating, or edema, can be caused by a variety of factors unrelated to weight, including high sodium intake, poor lymphatic drainage, hormonal fluctuations, or lack of sleep. When individuals attempt to “fix” this through extreme calorie restriction, they often exacerbate the problem by stressing the body and slowing down the metabolism, which can ironically lead to more fluid retention.
Challenging the ‘Skinny to the Bone’ Trend
The current beauty landscape in some East Asian markets has seen the rise of the “skinny to the bone” aesthetic, a trend that prizes extreme thinness above all else. Lee Yu Bi has been vocal about her dislike for this trend, noting the irony that her past, pressured body shape might actually align with today’s standards.
“Nowadays, it seems everyone is aiming for the ‘skinny to the bone’ look. Ironically, my old body shape might fit the current trend, but personally, I don’t like it,” she stated in her Bali vlog. Instead, she advocates for a more balanced appearance, suggesting that a “slightly fuller look” appears healthier and more beautiful.
This shift in perspective is not just about aesthetics; it is about the reclamation of happiness, and health. Lee Yu Bi emphasized that “letting go a little brings more happiness,” moving away from the rigid control and anxiety that characterized her early career.
The Holistic Path to Wellness
Beyond the rejection of extreme thinness, Lee Yu Bi has highlighted the pillars of health that she now prioritizes. Rather than restrictive dieting, she focuses on the systemic functions of the body to manage her appearance and well-being.
She identified three core components of health care: eating well, sleeping well, and managing stress. According to Lee Yu Bi, these factors are the primary drivers of overall health and are far more effective at managing conditions like facial swelling than extreme weight loss. What we have is supported by medical consensus, as chronic stress and sleep deprivation elevate cortisol levels, which can lead to systemic inflammation and fluid retention.

Her commitment to health is also visible in her daily routines, though the transition has not been without its challenges. In a separate video, “Tokyo 48-Hour Vlog, From MAPS Photoshoot Behind-the-Scenes to Omotesando Shopping,” uploaded to her YouTube channel, she showed the lingering pressures of the industry. In the vlog, she was seen skipping breakfast and using probiotics and vitamins to manage bloating before a photoshoot, admitting, “I’m so hungry,” while attempting to maintain her figure for the camera.
This contrast—between her advocacy for health and the reality of professional photoshoots—illustrates the ongoing struggle celebrities face. Even those who recognize the toxicity of extreme beauty standards must often navigate a professional environment that still demands them.
Key Takeaways on Healthy Body Image
- Bloating $neq$ Fat: Facial swelling is often a result of circulation issues or systemic inflammation, not necessarily an increase in body fat.
- The Danger of External Validation: Being pressured to lose weight while already underweight (e.g., at 42kg) can lead to severe health risks and psychological distress.
- Holistic Recovery: Regular exercise, adequate sleep, and stress management are more effective for long-term wellness than restrictive dieting.
- Rejecting Extremes: Moving away from trends like “skinny to the bone” in favor of a healthier, fuller appearance can improve overall mental well-being.
Conclusion: Redefining Beauty Standards
Lee Yu Bi’s journey from a place of extreme pressure and self-doubt to one of health advocacy is a significant step in redefining beauty standards within the entertainment industry. By openly discussing the fact that she was told to lose weight while weighing 42kg, she exposes the often-irrational demands placed on women in the public eye.
The transition from focusing on a number on a scale to focusing on circulation, nutrition, and mental health is a vital shift. As we move forward, it is essential that the conversation around “fitness” and “beauty” evolves to prioritize physiological health over aesthetic trends that promote fragility.
The next step in this cultural shift will likely involve more industry professionals speaking out against unrealistic weight mandates for performers. We encourage our readers to share their thoughts on how beauty standards have evolved in their own lives and to prioritize sustainable health over fleeting trends.
