aespa's Karina Once Lost 4kg in One Day as a Trainee: Here's the Extreme Method She Used

aespa's Karina recently revealed that she once lost 4kg in a single day as a trainee, disclosing on the JTBC variety show Naengjanggo-reul Butakae (Please Take Care of My Refrigerator) that extreme weight fluctuation was a real part of her pre-debut life. The admission landed differently against the backdrop of polished idol presentation: this was a specific, unglamorous account of what meeting a weigh-in actually looked like.

Karina told the show that during her trainee years she could gain or lose as much as 4kg in the span of a single day, describing herself as "extremely elastic" when it comes to weight. The crisis she described was straightforward: she ate freely one day, stepped on the scale, and found she had gained 4kg overnight. The problem was that she had to submit her weight the following morning.

Her solution was layered and literal. She cranked the heat in the practice room, pulled on leggings, sweat pants, a zip-up hoodie, and a padded jacket over all of it, then ran and sang alongside her fellow members. After that session she went home and soaked in a half-bath for roughly an hour. By the time she weighed herself again, she said, the 4kg had disappeared.

She added, with the kind of self-deprecating timing that lands well on variety television, that she could not pull the same routine today: "Now that I'm older, I can't eat like that or work out like that. I really feel like I've aged." It got a laugh, but the underlying detail about trainee weigh-in culture was not lost on the audience.

The television appearance came shortly after Karina posted several photos from a festival on her Instagram, accompanied by a rain emoji. The images showed her in a white backless dress, and the comments focused on her proportions and the way the dress fit. Fans noted that her silhouette read as the result of defined structure rather than simple thinness, and the post drew the kind of immediate, enthusiastic response her styling choices tend to generate.

The two moments together paint a familiar but still striking contrast: the composed visual output on social media, and the candid account of what the years before that looked like.
