Anyone know of any breastfeeding safe diet plans? I need to lose weight after this baby is born for my health. I know you have to take in more calories while breastfeeding but seeing as I already take in more than the healthy standard I think I could could cut calories without cutting them too low. I have heard breastfeeding itself can help you lose weight but I didn't lose very much in the 22 months I breastfed my daughter. I feel like the weight I did lose was more because I was no longer pregnant than because of breastfeeding. I was 300lbs when I had my daughter and got down to 250 before I got pregnant again but most of it was lost weight after she was born. I was 220 when I got pregnant with her. I was 250 this time and now I'm up to 285 and trying really hard not to get back to 300.
