Randy Jackson – Gastric Bypass Surgery / 130 pounds
Randy Jackson is one of the most famous American Idol judges, and we have to be honest, the audience loved him. However, his everyday trials and tribulations, along with his busy work routine, left him no time to have a healthy nutrition, and his stress and love for bad quality food resulted in him gaining a lot of extra pounds. After taking a break from the show, he decided to go under the knife, and his gastric bypass surgery helped him drop 130 pounds. He later returned to American Idol and he looks healthier than ever.
