The Jordin Sparks Diet

Jordin Sparks lost 50 pounds last year and has managed to keep the weight off with a healthy diet. The singer says she stays away from airport food and eats lots of fruits and veggies. 

"It's been so crazy... that's where really watching what I eat comes into play," Sparks said. "I've been trying to stay away form all of the stuff at the airports, because that's where I've been living. I've been trying to eat a lot of salads, apples, fruits -- I've been trying to stick with things like that so I can snack on those instead of being like, 'Oh look, a bag of chips! I'll just have those!'"

Sparks admits there is one indulgence she can't stay away from. 

"... My mom's sweet potato casserole. It's a good thing she only makes that once a year because I would eat it all day long!"
