Personal experience, don't take medicine to lose weight, dieting is harmful to your health. You can practice yoga to lose weight four months after delivery and lose weight quickly. Don't think yoga is difficult, you can sign up for classes or buy CDs at home like me. If you have time, you can do it for an hour every day. If you have too much time, you can do it twice a week, each time 1 hour, which can not only lose weight, but also enhance your physique.
