These Celebrities Went Through Intense Body Transformations - Page 47 of 61

Randy Jackson

With a poor diet from being constantly on the road as a music producer for such iconic acts as Bob Dylan, George Michael, Bruce Springsteen and Mariah Carey, Jackson weighed 350 pounds when he became one of the first judges on American Idol in 2002. After finding out he had diabetes, he opted for gastric bypass surgery to quickly drop 130 pounds. His weight continues to fluctuate to this day, but within a much tighter range.
