Randy Jackson is everywhere—judging American Idol, producing the MTV series America’s Best Dance Crew, playing bass guitar, producing music, and even trying his hand at designing with his Randy Jackson Eyewear line. But the place he’s happiest is at home, hanging out with his wife, Erika, and three children—daughters Taylor, 18, and Zoe, 13, and son Jordan. 11. Since losing over 100 pounds with the help of gastric- bypass surgery in 2003, Jackson has been on a mission to improve his family’s health, insisting on more activity for everyone and lightening up all their Southern-fried favorite foods. And he’s helping others do the same. “I wrote my book (Body With Soul) because I wanted people to hear from someone in an ongoing battle,” he explains, “and people have really responded. They said, ‘Finally, this is something for the regular person—who’s going to birthday parties and eating sweets.’ You have to be realistic.”
