Beyonce said she gained 50 pounds during her pregnancy and lost it quickly by breast feeding
She tells People Magazine,
'I lost most of my weight from breast-feeding and I encourage women to do it; it's just so good for the baby and good for yourself.'I counted calories. I worked out maybe three to four times a week. I did a lot of walking in the beginning and now I'm running. But I had to work my way up. I couldn't just go right from being pregnant to running.
