[MyDaily = Reporter Kim Ha-young] Lee Su-hyun, a member of the sibling duo AKMU, has revealed the dramatic process that led her to lose roughly 30 kilograms.
On April 17, she uploaded a video to her YouTube channel titled "Everything About the Lee Su-hyun Blooming Project," where she opened up about overcoming a slump and the weight-loss journey that followed.
She pointed to a suggestion from her older brother, Lee Chan-hyuk, as the catalyst. While preparing to move, he casually proposed, "Let’s try a detox with a fresh mindset"—initially suggesting just three days. That informal proposal, she said, turned out to be the beginning. Knowing she might postpone exercising, she accepted when a coach offered to come to her home; a routine formed naturally and eventually evolved into a live-in training program.
During that process, she decided to document her transformation. She hadn’t yet committed to returning to YouTube, but feared she would regret not recording her progress if she succeeded, so she chose to release the yearlong footage when she resumed her channel.
The subsequent video shows the full diet and training regimen. She said her initial goal was to lose 25 kilograms, with a longer-term target of 40 kilograms. For weeks she ate an almost entirely vegetable-based diet as she adapted to healthier food choices.
The process was far from easy. She admitted there were many moments she wanted to quit, but she resolved not to give up. She recalled a fasting program she did with Lee Chan-hyuk and their trainer as so grueling she never wants to repeat it.
She also shared details of her daily routine. Each morning at 7 a.m., fasting, she began with a swim, then followed a controlled diet and a variety of workouts. If the planned training fell short, extra sessions were added, keeping the regimen intense. She repeated activities like badminton and running, and the group continued this live-in training for about 22 days.
As a result, Lee Su-hyun says she lost roughly 30 kilograms from her highest weight. She’s now in a phase of learning self-regulation, since maintenance depends on her, and plans to continue losing weight more gradually. She added that she’s satisfied with her current appearance and does not want to become overly focused on looks.
More importantly, the transformation has become a shift in her outlook on life, not just on weight. She emphasized that the most important lessons were learning to care for herself and to practice restraint, and that she’s determined to value what’s ahead rather than dwell on past regrets.
In closing, she said she finds her present self—anticipating the future—remarkable, and that realizing she can change has made life more enjoyable.
