Reba McEntire
Age: 65
Fountain of Youth: Reba has a daily exercise routine of walking and Pilates, but she credits her diet for helping to keep her healthy and energetic.
Her Secret: “I splurge every once in awhile, but I do try to watch what I eat, stay away from complex carbs and eat as much protein and vegetables as possible,” Reba tells OK magazine. “I fall off the wagon quite a bit, but I try. I read somewhere if you eat like a king in the morning, a princess at lunch and a pauper at dinner, you’ll do well.”
