The Seoul Stage Greeting and Fan Interaction
The event, held to celebrate the cinematic success of IU’s most recent large-scale performances, provided a rare moment of direct interaction between the superstar and her fans, known as Uaenas. These concert films document IU’s historic performances, including her 2022 "The Golden Hour: Under the Orange Sun" at the Seoul Olympic Stadium, where she became the first Korean female artist to headline the venue.
During the casual Q&A segment, the atmosphere shifted when the topic turned to her personal routine. In response to the groans following her mention of boiled eggs for dinner, IU explained that her current regimen involves consuming two boiled eggs drizzled with olive oil. She claimed that this specific combination provides a level of satiety that lasts throughout the day, suggesting that the healthy fats found in olive oil are the key to suppressing hunger. She even went as far as to recommend the practice to her fans, suggesting they try it for breakfast to maintain fullness until evening.
This disclosure has ignited a debate within the K-pop community regarding the influence of celebrity dietary habits on public health, particularly given IU’s previous history with extreme weight loss measures and her subsequent public condemnation of those very practices.
A History of "The IU Diet" and Its Cultural Impact
To understand the weight of IU’s recent comments, one must look back at the origins of what became known globally as "The IU Diet." In the early years of her career, specifically around 2013, IU revealed a weight loss plan she utilized to prepare for television appearances and album promotions. The regimen consisted of:
- Breakfast: One apple
- Lunch: Two sweet potatoes or two bananas
- Dinner: One protein shake
At the time, this extreme calorie restriction—estimated to be fewer than 600 calories per day—went viral, with thousands of fans and influencers attempting the "IU Diet Challenge" on platforms like YouTube and Instagram. However, as IU matured into a leading figure in the Korean entertainment industry, her perspective on these habits shifted significantly.
In 2021, during an appearance on the tvN show You Quiz on the Block, IU addressed the lingering popularity of this diet. She expressed deep concern that the regimen was still circulating online as a viable lifestyle choice. She clarified that she had only followed that extreme plan for a very short period in her early twenties and admitted that she would no longer be able to sustain such a diet while maintaining her rigorous performing schedule. "If I did that now, I wouldn’t be able to sing a single song," she told the hosts, warning viewers that such habits could lead to long-term health complications and vocal strain.
Nutritional Analysis: Eggs and Olive Oil
The "new" diet mentioned at the Seoul theater—boiled eggs and olive oil—represents a shift toward high-protein and high-fat intake, which differs from the carbohydrate-heavy "apple and sweet potato" plan of her past. From a nutritional standpoint, protein and healthy fats are known to trigger the release of satiety hormones like cholecystokinin (CCK) and peptide YY (PYY), which signal to the brain that the body is full.
Olive oil, a staple of the Mediterranean diet, is rich in monounsaturated fatty acids, particularly oleic acid. Research suggests that these fats can slow gastric emptying, keeping food in the stomach longer and extending the feeling of fullness. However, health experts caution that while these components are healthy in moderation, using them as a primary meal replacement—as suggested by IU’s dinner plans—can lead to significant nutritional deficiencies.
A standard large boiled egg contains approximately 78 calories, 6 grams of protein, and 5 grams of fat. Two eggs, combined with a tablespoon of olive oil (roughly 120 calories), would total approximately 276 calories. For an active performer like IU, whose concerts often last over three hours and involve intense vocal work and choreography, such a low-calorie intake for dinner remains on the extreme end of the spectrum, despite the inclusion of healthy fats.
The Pressures of the K-pop Aesthetic
The scrutiny surrounding IU’s diet is emblematic of a broader issue within the South Korean entertainment industry. For years, "trainee diets" and extreme weight loss have been documented as part of the rigorous preparation required for idols. The "45kg" (approx. 99 lbs) standard has long been an unspoken benchmark for female idols, regardless of their height or bone structure.
IU, who stands at approximately 162 cm (5’4"), has been open about her struggles with body image in the past. In earlier interviews, she admitted to suffering from an eating disorder during the height of her early fame, noting that she sought treatment to overcome bulimia. This history makes her current comments particularly sensitive for fans who have followed her journey toward health and self-acceptance.
Industry analysts suggest that the pressure to maintain a "camera-ready" physique is constant, especially when an artist is promoting a film or a concert series. Even as IU has transitioned into a more "artist-focused" phase of her career—prioritizing her songwriting and acting over the traditional "idol" mold—the expectations of the public and the industry regarding physical appearance remain a significant factor.

Public and Professional Reactions
The reaction to IU’s latest comments has been polarized. On social media platforms like X (formerly Twitter) and Korean community sites like TheQoo, fans expressed a range of emotions. Many Uaenas expressed worry, noting that IU’s schedule is incredibly demanding and that two eggs are insufficient for a dinner meal. "We want her to be healthy and eat well so she can keep singing for a long time," one fan wrote, echoing the sentiments of those who groaned during the theater event.
On the other hand, some observers noted that IU’s tone was casual and that she may have been referring to a specific "maintenance" day rather than a permanent lifestyle change. However, given her massive influence—IU has over 30 million followers on Instagram—even casual remarks about dieting can have a profound impact on younger fans who look to her as a role model.
Dietitians and medical professionals in South Korea have frequently used IU as a case study when discussing the dangers of celebrity diets. Following her latest revelation, some have pointed out that while olive oil is a superior source of energy compared to the low-fat "apple diet," it still lacks the essential vitamins, minerals, and complex carbohydrates required for a balanced diet.
Implications for the Future
As IU continues to break records in the music industry and receive critical acclaim for her acting roles in films like Broker and dramas like My Mister, her influence only grows. This influence carries a responsibility that IU has acknowledged in the past, particularly when she warned fans against following her younger self’s mistakes.
The re-release of her concert movies serves as a reminder of her vocal prowess and the sheer physicality required to perform at her level. The irony noted by many is that to achieve the "Golden Hour" of her career, she requires more sustenance than a few eggs can provide.
This latest episode highlights the ongoing tension between the health of the artist and the aesthetic demands of the entertainment industry. While IU has made significant strides in moving away from the "starvation" diets of her youth, her recent endorsement of a highly restrictive meal indicates that the pressure to maintain a specific weight remains a persistent element of her professional life.
As the discussion continues, the focus remains on whether the industry will eventually move toward a model where an artist’s health is prioritized over their silhouette, and whether influential figures like IU will continue to navigate the fine line between personal habits and public influence. For now, fans remain hopeful that the "Nation’s Little Sister" turned "Nation’s Artist" prioritizes the longevity of her voice and well-being over the temporary satiety of a restrictive diet.
