Actor Ko Kyung-pyo is drawing attention with his slender face.

Ko Kyung-pyo posted a recent photo on his social media on the 16th. In the photo, Ko Kyung-pyo is seen posing with a slim jawline, a pale face, and round glasses. Additionally, his slightly weary expression raised concerns about whether he had dieted excessively.

Internet users reacted with comments such as "He lost weight, but his expression has darkened" and "He is becoming unhappy," while supporting Ko Kyung-pyo's weight loss.

Ko Kyung-pyo revealed that he recorded his heaviest body weight of 93 kg in February of last year. He appeared on the YouTube channel "Ju Jeong-gi Go" and noted, "I had never exceeded 90 kg before, but before I knew it, I was at 93 kg," adding, "I felt I was going to continue to gain weight uncontrollably, so I decided it was time to manage it."

He stated that this weight gain was due to personal reasons rather than his work activities. Moreover, Ko Kyung-pyo said, "I've gained a lot of weight, but I am becoming happier."

Although Ko Kyung-pyo boasts a handsome visual through dieting during active periods, he tends to gain weight during inactive periods, earning him nicknames such as "an actor whose weight changes significantly before and after payment" and "an actor with a rubber band weight."

Meanwhile, Ko Kyung-pyo recently appeared on the tvN variety show "Sixth Sense: City Tour."
