Recently, a video titled “If You Do This, You Can Become Like Seulgi Too. Red Velvet Comeback Vlog” was uploaded to her “Hi Seulgi” YouTube channel.

In the video, Seulgi shared, “Since Red Velvet’s comeback is less than a month away, I decided to compile my self-care routine and film a vlog. As of the filming date, we have already shot the music video. At that time, I got my weight down to 45.3 kg.”
She explained that home workouts and diet management helped her fit into her stage outfits. However, enjoying the catering truck food on set caused her to gain 2 kg back. She expressed her determination to restart her diet before official promotions begin.
Behind-the-scenes footage revealed Seulgi showing her scale at 45.3 kg and displaying her slim waist. To maintain her physique for outfits exposing her stomach, she focused on eating minimal meals while squeezing in core exercises whenever possible.
Before restarting her strict regime, Seulgi enjoyed tacos as a final treat paired with a zero-calorie soda. She admitted craving foods like tteokbokki, fried chicken, and ramen wrapped in kimchi, but chose lighter options to keep her appetite under control.


Seulgi then introduced her upgraded “stray cat diet” menu—a combination of tuna, dried seaweed, rice, and cabbage wraps. She highlighted that cabbage wraps offer great satiety and ease digestion, helping her lose 2 kg quickly while keeping her stomach comfortable.
To complete her routine, Seulgi demonstrated her evening home workout targeting her abs and correcting posture issues like turtle neck and rounded shoulders. Despite the exhaustion, she encouraged fans and proudly revealed her firm, toned abs.
