Carrie Underwood has discussed her post-baby weight loss with "Shape" magazine.
Underwood looks healthy and slim on the publication's cover, less than eight months after welcoming son Isaiah with husband Mike Fisher.
"After I had Isaiah, my goal was to take control of my body again," she shared.
"I gained only 30 pounds, which is the recommended amount, and I exercised throughout my pregnancy ... When I got the OK from my doctor, I started exercising [after giving birth]. Now we box and hike trails, among other things."
"I'm vegan and I love bread, but recently, I started making dinner a breadless meal," she added. "I'll have a bowl of oatmeal for breakfast, and I'll make a sandwich on Ezekiel bread for lunch, but in the evening I'll have protein and vegetables and no bread. When I wake up, my belly is flat!"Underwood and Fisher, a 35-year-old NHL player, have been together since 2008, and married in July 2010.
The couple welcomed Isaiah on Feb. 27, and the singer recently delighted fans by posting a photo of her son playing a miniature piano.
She will debut her fifth studio album, "Storyteller," on Oct. 23, and released the song "Heartbeat," a collaboration with Sam Hunt, this week.
