On August 24, veteran K-pop artist and actress Nam Yujeong appeared as a guest on KBS Cool FM’s Park Myung Soo’s Radio Show to discuss her recent professional activities, most notably her high-energy performance at the Waterbomb Sokcho 2026 music festival. During the broadcast, the former BBGIRLS member addressed persistent rumors regarding her dietary habits and shared insights into the rigorous physical preparation required for one of South Korea’s most visually demanding summer events. The conversation provided a candid look at the intersection of celebrity health, public perception, and the evolving standards of fitness within the Hallyu industry.
The discussion was prompted by host Park Myung Soo, who noted the significant effort typically required for artists to prepare for the Waterbomb stage. The festival, which has grown into a cultural phenomenon since its inception in 2015, is famous for its water-based special effects and a dress code that often emphasizes athletic and bold summer attire. Consequently, performers frequently undergo intensive "body management" cycles to ensure they meet the aesthetic and physical demands of the show. When asked how she prepared for her August 22 appearance in Sokcho, Nam Yujeong confirmed that while she maintained a strict regimen, many of the rumors circulating in the media regarding her methods were based on a misunderstanding of her social media content.
The Misconception of the Three-Tomato Diet
A central point of the interview was the clarification of a viral report claiming that Nam Yujeong’s diet consisted solely of "three pieces of tomato." This narrative gained traction after the artist posted a photograph of grilled tomatoes on her social media account. In the fast-paced world of digital celebrity news, this single image was interpreted by some outlets as a comprehensive meal plan, leading to concerns among fans and a skewed perception of her health practices.
"Honestly, I strictly followed my diet," Nam explained during the radio broadcast. "But there was an article about my diet saying I only ate ‘three pieces of tomato.’ That was because I’m not good at cooking, and I had posted a picture on social media of grilled tomatoes. But that is absolutely not my diet." She went on to emphasize the impossibility of maintaining a professional performance schedule on such a caloric deficit, stating firmly, "You can’t live like that."
Nam’s clarification highlights a recurring issue in the K-pop industry: the sensationalism of "idol diets." For years, the public has been fascinated and sometimes troubled by the extreme weight-loss methods reported by various stars. By debunking the tomato-only rumor, Nam Yujeong advocated for a more balanced approach to fitness, noting that her physique was the result of "consistent exercise and a healthy diet" rather than starvation. Park Myung Soo, a veteran entertainer familiar with the rigors of the industry, empathized with her, noting that such extreme restriction would lead to dizziness and an inability to perform. Nam agreed, pointing out that her "blood sugar would drop," rendering the high-octane choreography of a festival set impossible to execute.
The Physical Demands of the Waterbomb Festival
To understand the necessity of Nam Yujeong’s fitness regimen, one must look at the nature of the Waterbomb festival itself. Unlike traditional concert venues, Waterbomb takes place outdoors during the height of the Korean summer. Artists are frequently drenched by water cannons and must navigate a slippery stage while maintaining vocal stability and complex dance routines. The event held on August 22 in Sokcho, Gangwon Province, was no exception.
Waterbomb has transitioned from a simple music festival into a major branding opportunity for artists. Success at the festival often leads to viral "fancams" and a surge in public interest, as seen with previous "Waterbomb Goddesses" like Sunmi and Kwon Eunbi. For an artist like Nam Yujeong, who is currently navigating a solo career after years in a group, the stakes for such a performance are high. The physical preparation involves not just aesthetic toning but cardiovascular endurance to ensure that the performance remains sharp despite the heat and the weight of water-soaked costumes.
Nam’s commitment to a "healthy diet" and "consistent exercise" reflects a broader shift in the K-pop industry. While the early 2010s were defined by reports of "paper cup diets" and extreme fasting, the current generation of idols—and the veterans who lead them—are increasingly emphasizing "lean muscle" and "wellness." This shift is partly due to the increased difficulty of modern choreography and a growing awareness of long-term metabolic health among performers.
A Career Defined by Resilience: From Brave Girls to Solo Success
Nam Yujeong’s journey to the Waterbomb stage is marked by a notable history of resilience. She originally debuted in 2016 as a member of the second generation of Brave Girls, a group under Brave Entertainment. For several years, the group struggled to find mainstream success, often performing at remote military bases for soldiers. It was this dedication to their craft that eventually led to their miraculous 2021 resurgence when a compilation video of their song "Rollin’" went viral on YouTube.
The "Rollin’" phenomenon became a landmark event in K-pop history, symbolizing the power of fan support and the possibility of "reversal" success. During this period, Nam Yujeong gained significant popularity for her bright smile and charismatic stage presence, earning the nickname "Kkobuk-jwa" (Squirtle) due to her resemblance to the popular Pokémon character.
Following the expiration of their contracts with Brave Entertainment, the members transitioned to Warner Music Korea, rebranding as BBGIRLS. However, in April 2024, it was announced that Nam Yujeong would be leaving the group to pursue individual paths. Her appearance at Waterbomb Sokcho 2026 as a solo entity signifies a new chapter in her career. The radio appearance on Park Myung Soo’s show served as a platform to re-establish her individual brand, showcasing a more mature and health-conscious image to the public.
The Broader Impact of Health Advocacy in Entertainment
Nam Yujeong’s decision to publicly correct the "three-tomato" rumor carries weight beyond her personal brand. In South Korea, where beauty standards are rigorous and often scrutinized, celebrities’ vocalizations about healthy living can influence their young fan bases. By admitting that she follows a "strict diet" but qualifying it as one that is "healthy" and paired with "consistent exercise," she provides a more realistic template for fitness.
Data from various health organizations in South Korea suggest that the prevalence of eating disorders and body dysmorphia among young people is a growing concern. When high-profile figures like Nam Yujeong debunk "starvation" myths, they contribute to a counter-narrative that prioritizes functionality and health over dangerous aesthetic shortcuts. Her mention of "blood sugar" levels is a practical reminder of the biological realities that even the most famous stars must respect.
Furthermore, the transparency regarding her lack of cooking skills—attributing the tomato photo to a simple, un-chef-like meal rather than a lifestyle choice—humanizes her. It breaks the "perfection" veneer often associated with idols, making her more relatable to a general audience.
Chronology of Recent Events
The timeline of Nam Yujeong’s recent activities illustrates her transition from a group member to a focused solo entertainer:
- April 2024: Official departure from BBGIRLS is announced, marking her intent to focus on acting and solo music activities.
- Early Summer 2024: Preparation begins for the summer festival circuit, involving a disciplined fitness and dietary regimen.

Conclusion and Industry Outlook
The conversation between Nam Yujeong and Park Myung Soo serves as a snapshot of the current state of the K-pop industry—a space where the pressure to maintain a specific image remains high, but where there is also an increasing room for honesty regarding the work required to maintain that image. Nam’s refusal to let a false dieting narrative stand is a testament to her experience and her commitment to a sustainable career.
As she moves forward with her solo activities and acting roles, Nam Yujeong appears to be positioning herself as an artist who values longevity. Her performance at Waterbomb Sokcho 2026 was not just a musical set but a demonstration of her readiness to remain a prominent figure in the entertainment landscape. By balancing the "bold costumes and performances" expected of a festival headliner with a grounded, health-first philosophy, she sets a professional standard for her peers and a healthy example for her fans.
The entertainment industry will likely continue to see a demand for high-visibility events like Waterbomb, which blur the lines between music, fashion, and fitness. However, as veterans like Nam Yujeong lead the way in demystifying the "secret" to their success, the conversation is shifting from "how to be thin" to "how to be strong." This evolution is essential for the well-being of the artists and the health of the industry as a whole. For Nam Yujeong, the "secret" to her body management was never a single vegetable; it was the discipline to treat her body as the professional instrument it is.
