You actually loose weight if you're breastfeeding

And obviously you have to avoid certain supplements while breastfeeding.

You can eat a healthy well balanced diet which would help with weight, you can work out to. But you can't do any strict crazy crash diets which aren't healthy anyways. You need about 300 extra calories per day while breastfeeding to make sure your baby gets proper nutrition

Not necessarily. You just don't want to cut a ton of calories because you burn 300-500 calories a day breastfeeding. So you can "diet" by eating super healthy, but make sure you're getting enough healthy calories and water to produce enough milk. I waited until he was about 7 ish months old and I had a strong supply before kinda testing the water to see what I could and couldn't do as far as diet.

@mommytobe15, I think u can't because you need more nutrients in your body to feed the baby
