It's been revealed that Mighty Mouth's Sangchu lost a whopping 22 pounds in just ten days in order to film for Mighty Mouth's new music video, "La La La". On June 20th, Sangchu revealed two photos that showed his 'Before & After' self. In the first photo, he has a big belly that is sticking out, but in the second photo, he is seen posing with perfect 'six-pack' abs. His agency explained, "In order to film for a scene where he had to wear a swimsuit, Sangchu replaced his meals with pumpkin sweet potatoes and ran around the Han River everyday. Through this method, he was able to lose 1 kg a day for ten days, and lost a total of 10 kg (about 22 lbs), making a rapid and dramatic transformation from a heavier body to one with perfect 'six-pack' abs. Although he only had a short time to lose weight, he kept up a strict diet and exercise routine." After seeing the photos, netizens left comments such as, "Is it really possible to do that in 10 days?", "Whoa he has perfect abs", and "I want to receive training lessons from Sangchu."
