INFINITE's Sungjong has been known for his thin figure but recently brought shock to fans after he revealed his weight.

On the SBS Power FM radio show '2 PM Escape Cult Two Show' that aired on February 3, Sungjong revealed his weight and confessed that he had lost more weight recently.

He shared, "This is the first time I am sharing this. I actually weighed 54 kg (~119 lbs) but then I lost weight. I like riding bicycles so I ride from Sangam to Apgujung. I ride all day. I sweat so I lose my appetite."

DJ Kim Tae Gyun asked, "So, how much do you weigh now?" Sungjong shyly shared, "49 kg (~108 lbs)" The DJ was shocked and asked, "Aren't you also tall?" and Sungjong replied, "I'm almost 180 cm (5'11")."

Sungjong shared, "I exercise diligently, and I don't eat. I eat two meals a day, but I eat one egg, one pack of soy milk, and one pack of red ginseng juice," which left fans shocked. With many people expressing their concern for the singer, Sungjong promised he would gain weight, saying, "I will gain more weight from now on."
