Idol's Randy Jackson Has a Body With Soul

Randy Jackson calls his diagnosis with Type II diabetes a double-edged sword. It was bad, because diabetes is a disease that never goes away. But it was good, because he had to do something about it. What did he do? He lost weight -- and lots of it -- and changed his entire lifestyle. He dishes up the skinny in his new book Body With Soul: Slash Sugar, Cut Cholesterol, and Get a Jump on Your Best Health Ever.

While Jackson was the recipient of gastric bypass surgery, he says it wasn't meant to be an easy fix. A lot of hard work is still necessary after this expensive and risky procedure (just ask Karla), which certainly is not for everyone. It worked for Jackson, though, since he had a disease and needed to do something quickly.

Post-surgery, Jackson is all about changing habits, and he fully endorses the morsel diet -- just have a bite and then move on. And no seconds either. Hey, we all know what's good and bad for us, says the American Idol judge. Eat healthy food and move. Does it get any easier than that?
