Hu Gak has returned to the public's eye… a little chubbier.

Hu Gak performed his hit song "Don't Forget Me" on KBS 2TV show 'Yoo Heeyeol's Sketchbook' on January 6th.

MC Yoo Hee Yeol commented after the performance that "compared to the last time he had been on the show on September, Hu Gak looks like he has gained weight." He asked Hu Gak whether the weight gain was due to the yo-yo effect brought on by his previous weight loss efforts. Hu Gak confessed that he had stopped dieting because he thought he was done with media performances in January.

While discussing his rise to fame in 2011, Huh Gak also joked that all the love he got from his fans may have contributed to the weight gain.
