"I Think the Yo-Yo Effect Has Started" Goo Hye-sun Reveals Sudden Concern After Losing Weight to 46 kg... Photo Shows a Different Side

[Sportschosun Reporter Kim Soo-hyun] Actress Goo Hye-sun has opened up about her concerns over regaining weight after successfully dieting down to 46 kg.

On the 18th, Goo Hye-sun shared recent photos along with the caption, "I think the yo-yo effect(?) has started, so I'm doing yoga."

In the photos, Goo Hye-sun is seen focusing on yoga while wearing comfortable, everyday-style yoga wear with a pure and graceful look. Even with minimal makeup and a natural appearance, she drew attention for her unchanged beauty.

In particular, Goo Hye-sun, who recently drew attention for her successful weight loss, has continued to receive interest for her steady self-care.

Previously, she made headlines by sharing a photo of a scale display showing 46.78 kg.

Goo Hye-sun had earlier said she was dieting with a goal of losing 13 kg, earning strong support from fans. She reportedly succeeded through healthy habits such as getting enough sleep and following a low-sodium diet.

As Goo Hye-sun honestly shared her concern, saying, "I think the yo-yo effect(?) has started," fans have continued to show interest. However, in the actual photos, she still appears to maintain a slim figure, which has also drawn attention.

Meanwhile, Goo Hye-sun debuted as a commercial model in 2002 and rose to fame through dramas such as Boys Over Flowers. After graduating from Sungkyunkwan University in 2024, she entered the graduate school of KAIST and graduated early in January this year.

She also attracted major attention by launching a portable hair roller she personally developed. The patented product improves portability, eco-friendliness, and functionality. However, when its high price was revealed — 13,000 won for one and 25,000 won for a set of two — it also sparked some controversy.
