ITZY recently held its first fan meeting and fans could not help but notice Yuna's slim figure. While performing "Twenty" on stage, Yuna's rib cage visibly showed that fans started to raise concerns about her health.

Photos and videos of Yuna performing in front of the audience had stirred discussions online. The girls were wearing shorts and crop tops at the event and possibly due to strong lighting, Yuna's ribcage showed up.

AllKpop noted the netizens' reactions, with one saying it was kind of scary to see her like that. Another said she seemed to have nothing but skin and bones.

Another one doubted the saying that some people could not gain weight no matter how much they ate. "People who look like that always have a reason," she said. "It's honestly the fault of this industry, where female idols are not allowed to eat."

A different netizen felt like she was watching a skeleton dance through Yuna. While another one said she reminded her of Wendy when she followed an unhealthy diet during her debut days.

However, some fans opposed these claims. One said Yuna only had a type of body that her ribs showed very prominently.

In fact, she revealed she ate pizza before she went on the stage for the fan meeting. A different fan added it was just the effect of the stage lights and some photo effects because she actually looked healthy.

A netizen then assured Yuna is healthy both physically and mentally. Another then asks others to leave her alone and stop body-shaming her.

Yuna has been known for having a thin body. She has a small waist and figure that make her known aside from her stunning stage presence and skills.

She possesses a natural hourglass figure and a tiny waist that has been the envy of many. She is also a healthy eater and fond of exercising, per Koreaboo.

Many also pointed out her other photos at the event where her rib cage was not showing. Some explained that the lighting only exaggerated her body's shadows, making her rib cage look like it was protruding.

As the concerns for her health are continuously growing, some fans ask her company to keep a close eye on her health, knowing she is just in her teens. Yuna is only 18 years old. Young girls are said to feel pressured much easier in a demanding industry like this.
