I dieted after having my babies and while breast feeding to just shed the weight as fast as possible. As long as you don't go lower than 1500 calories you will be fine. I was told by my doc and read it on many health websites that you can eat low cal and not disrupt you milk supply as long as you don't go too low. So if you stay between 1500 and 1800 calories that is enough to still give you energy and give your body enough food to make enough milk.
