IU lost 5kg in five days
The K-pop star IU has always been admired for her fantastic figure. However, she has also been open about her struggles with anxiety and eating disorders. In 2013, IU revealed on SBS's Night of TV Entertainment that she lost 5kg in five days by consuming only one apple, two sweet potatoes, and a protein powder drink per day. This extreme diet plan was adopted by many of her fans, becoming known as the "IU diet challenge".
IU's weight loss methods, especially her diet, have become some of the most searched on the internet. While weight loss is not frowned upon in the K-pop industry, with idols often losing more than 10 pounds every three months, IU's extreme diet caused concern among her fans. Despite this, many people tried the IU diet challenge to see if it would help them lose weight.
IU herself has acknowledged that her relationship with food has not always been healthy. In 2014, she opened up about her eating disorder on the talk show Healing Camp, Aren't You Happy, revealing that she had struggled with bulimia.

IU's diet was criticised for being unhealthy and triggering
The IU diet plan is named after the South Korean singer and actress Lee Ji-eun, also known as IU. The diet gained popularity after IU revealed that she followed this extreme diet to lose weight quickly for her role in the drama "Dream High". The IU diet involves restricting calories and cutting out certain food groups, typically eating only one type of food for each meal. For example, an apple or banana for breakfast, and a small portion of sweet potato or brown rice for lunch and dinner. The diet also prohibits snacking and consuming any beverages with calories. IU revealed that she lost around 5-7 kg in just a week by following this diet.
Despite its popularity, the IU diet has been criticised for being unhealthy and triggering. While IU has struggled with an eating disorder and anxiety herself, her diet plan has been criticised for promoting restrictive and potentially dangerous eating habits. The diet involves a very low calorie intake and a limited variety of foods, which may not provide adequate nutrition. This type of extreme dieting can lead to nutritional deficiencies, reduced metabolism, and other health issues.
Furthermore, the IU diet may be triggering for individuals with a history of disordered eating or body image issues. The promotion of a quick weight loss plan and the focus on a slim figure can perpetuate harmful diet culture messages and contribute to negative body image. As someone who has struggled with an eating disorder, IU's diet plan may unintentionally glorify or encourage disordered eating behaviours. It is important to recognise that everyone's body is different, and extreme diets like the IU diet may not be safe or sustainable for everyone.
In addition to the health concerns, the IU diet may also be criticised for its potential impact on cultural norms and expectations. As a popular celebrity, IU's influence extends beyond her fans and can shape societal ideals of beauty and body image. The promotion of a restrictive diet may contribute to a culture that values thinness over health and diversity. It is important to foster a positive relationship with food and body image, and extreme diets can detract from this goal.
While IU's journey towards healthier eating and exercise is commendable, it is important to approach her diet plan with caution. Seeking guidance from healthcare professionals or registered dietitians is advisable before embarking on any extreme diet. It is essential to prioritise overall health and well-being rather than solely focusing on weight loss.
