Singer Kim Tae-woo from K-pop veteran boy group g.o.d recently shed 8 kilograms in 13 days.

Kim, 35, uploaded two photos -- before and after his diet -- on his Instagram Monday, with a caption saying, “Comparing these photos, I can see that I have really lost weight. Never giving up. Hope you root for my diet.”

Kim earlier expressed his hope for having a slim and firm body, getting motivation from family photos of soccer player David Beckham, which went viral on social media for a while.

Kim is set to hold a concert in Ilsan on Nov. 28 as part of his national tour.
