Here is what the 31-year-old entertainer had to share with the mag:

via justjared.com On gaining 57 pounds during her pregnancy: “I didn’t have a lot of time to lose the weight because I scheduled a show three months after I gave birth, which I would never do again!”

On losing the weight: “I ate a very low-calorie diet. I stayed away from red meat and ate a lot of fish, replaced pasta and rice with quinoa.”

On her diet: “I always have breakfast, say, scrambled egg whites, a vegetable smoothie, or whole-grain cereal with low-fat milk. For lunch and dinner, I eat a lot of fish and vegetables. And throughout the day, I try to stay hydrated… I always treat myself to one meal on Sundays when I can have whatever I want. Usually it’s pizza, which is my favorite indulgence.”

Shape‘s editor-in-chief Tara Kraft on Beyonce: “Talking about weight can be a very touchy subject for women, but Beyonce was willing to do it because she wanted to make every woman out there feel like she too could achieve what she did.”
