Comedian Lee Guk-joo cautions against yo-yo dieting in new health message
South Korean entertainer Lee Guk-joo is drawing attention to the dangers of repeated weight loss and regain, urging fans to adopt steadier habits.
South Korean comedian and television personality Lee Guk-joo has spoken out against the cycle of losing and regaining weight, a pattern commonly known as yo-yo dieting. In comments highlighted by the daily Chosun Ilbo, she warned that repeated dieting can take a heavier toll on the body than maintaining a stable weight, even when that weight is above a person's ideal range.
Why the warning matters
Yo-yo dieting describes the experience of shedding kilograms through strict eating plans and then regaining them, sometimes more than before, once the routine ends. Nutrition researchers have long linked repeated cycles of weight loss and regain to a higher risk of metabolic changes, muscle loss, and frustration that can push people toward more extreme diets. Lee's message echoes that body of advice: short-term results can carry long-term costs.
Lee's own approach
Lee, who has been open about her own weight management journey, said she now focuses less on rapid drops on the scale and more on consistent, sustainable habits that support everyday health. She encouraged fans to be patient and to think of weight control as a lifelong process rather than a series of crash attempts.
Practical guidance for avoiding the cycle
- Set modest, realistic goals rather than chasing dramatic short-term losses.
- Build routines, such as regular meals and movement, that can be maintained for years.
- Seek professional advice before starting any restrictive eating plan, especially after multiple diet attempts.
