Jin Seo Yeon sets 3-month goal to lose 11kg

“It hit 60.17kg.” After revealing her current weight, actress Jin Seo Yeon has announced her next goal: losing 11kg over the next three months to reach a target of 49kg.

On the 28th, Jin posted her InBody measurement results on SNS, stating, “An unprecedented situation. Starting an 11kg weight loss operation. I will lose 11kg in 3 months. Target 49kg.” According to the results, her weight was 60.17kg, body fat percentage was 21.1%, skeletal muscle mass was 26.23kg, and body fat mass was 12.70kg.

Just eight days ago, Jin shared a candid reflection on her past dieting experiences. Recalling how she lost 28kg just 40 days after childbirth, she admitted, “It was a very unhealthy diet.” Rather than attempting the extreme, short-term weight loss of her past, she has opted for a more gradual three-month period this time.

The 49kg target is not a new one for the actress. During a 2023 broadcast, she revealed, “When I am working on a project, I am 48–49kg, and when I am not working, I am 53kg.” Given her long history of managing her weight through exercise and lifestyle habits, she is expected to follow her established routine.

Initial changes were noted quickly. On the 29th, Jin released her InBody results for her “second day of dieting.” Her weight was measured at 58.95kg, down from 60.17kg the previous day, representing a numerical decrease of approximately 1.2kg. However, weight fluctuations within a single day can be influenced by water retention or measurement conditions, so it is difficult to conclude that this represents a direct loss of body fat.

What is most notable is that Jin is taking a different approach than she has in the past. She previously emphasized, “I will not recommend dieting solely for appearance,” signaling her intention to manage her overall physical condition and lifestyle rather than focusing strictly on the number on the scale.

With a goal of dropping from 60.17kg to 49kg, all eyes are on how Jin, who described her previous extreme weight loss as “unhealthy,” will execute this three-month plan.
