Netizens are worried about f(x) Luna's diet.

The singer posted several photos on her Instagram on the 4th wearing a nude swimsuit with the caption, "Next time I'm gonna wear red..too much skin tone 💋 "

Netizens however expressed concern over her skinny body saying, "Isn't Luna supposed to stop going on a diet?"

Luna revealed in November last year that her goal was to lose 10kg but she has already lost 5kg and has an "ant" waist. She made an appearance on a variety show previously and said, "I've been on a diet and I've lost all my muscles. I haven't eaten carbs for almost 5-6 months."
