Red Velvet's Seulgi lost 2kg before comeback with tuna-ssam diet, shared on YouTube
Seulgi shared her pre-MV shoot diet on YouTube—tuna and seaweed one day, cabbage wraps the next. She dropped 2kg in a month.

Seulgi dropped 2kg before the MV shoot — here's what she ate
Red Velvet's Seulgi lost 2kg during her comeback preparation and has now shared exactly how she did it. On the 7th of last month, she uploaded a video to her YouTube channel Hi Seulgi (하이슬기) documenting the full month of diet and exercise management she ran before her comeback.
Two meals on rotation. The "street cat diet"—tuna, dried seaweed, and rice—alternated with cabbage ssam wraps in the lead-up to filming her music video. The 2kg came off fast.
"Before filming the music video, I alternated between eating tuna, seaweed, and rice ('street cat diet') and cabbage ssam, and it definitely made me lose 2kg quickly," Seulgi said.
Once the MV shoot wrapped, her weight crept back up. Her solution: cabbage and tuna ssam rice (양배추 참치 쌈밥) as her evening meal. The wrapping format kept hunger at bay. "Since I wrap it in ssam, the satiety is quite good."
(Cabbage ssam as a diet staple is not new, but the 'street cat diet' framing is very Seulgi.)
What the video shows
The Hi Seulgi upload covers the full pre-comeback body management arc. One month out, she started tracking both food and exercise, giving fans a real-time look at the prep that goes into a comeback cycle rather than just the finished result.
