Getting Back in Shape After Pregnancy

My sister (Baby Tyra's mom), who gave birth last September has been trying to get back in shape. I think it helps a lot that she's breastfeeding Baby Tyra and that she has been eating healthy food. But one thing she cannot do is exercising regularly because she is taking care of Baby Tyra all the time. She wanted to know what is the best weight loss pill in the market today. I told her that when she visits her doctor, she should ask for an advice on when she can start taking weight loss pills. From what I know, she can take weight loss pills after the lactating period is over.
