Engaged Carrie Underwood stays super slim by avoiding fast food on the road – but it's not easy.
"I think the hardest thing about what I do is eating [healthy] because we're all over the place," the singer, 27, told UsMagazine.com at Wednesday's Idol Gives Back.
"It's fast food, there's aftershow food, you get pizza, whatever," continued Underwood, who recently revealed she and fiance Mike Fisher set a wedding date (but wouldn't say when!). "I don't do that. I don't eat out ever."
"Every once in a while I have a day off and I might go to a restaurant — but no aftershow food and I keep my fridge stocked," she added.
She also makes "a point to get up and work out" before hitting the stage.
"It's all about making a conscious effort. I don't do anything crazy, but I definitely try to take care of myself," she told Us.
