Okay, maybe that's not her most tried-and-true diet tip, but the country singer certainly has a go-to barbecue joint: Hard 8 BBQ in Stephenville, Texas.
"I take all my out-of-town guests here, and they rave about it," she tells PEOPLE Country in its September issue. "In fact, I think they visit me just for the barbecue."
Where else are country stars getting their barbecue fixes? These digs have singers like Tim McGraw and Dolly Parton licking their fingers – and reaching for wet naps:
Country Tavern, Kilgore, Texas
"The best brisket and ribs I've ever had. And they've got traditional country on the jukebox. It just feels like Texas."
Blue Pig BBQ, Ardmore, Okla.
"It's pork barbecue. The name is kind of a dead giveaway, isn't it?"
Jack's Bar-B-Que, Nashville
"It's great food, and the atmosphere is always awesome in the middle of the honky-tonks."
Podnuh's, Baton Rouge, La.
"P-o-d-n-u-h-s – like saying partner, you know, in Louisiana you say 'podnuh?' Best beans. Nobody can stay in the car with me though."
Couser's Southern Restaurant, Nashville
"They have the best barbecue. When I first came to Nashville, I used to fill their salt and pepper shakers [in exchange for free food]."
