Point out that during the course of history, women have managed to breastfeed eating just about any and all sorts and combinations of food, or even none at all. Nature ensures that the baby gets what it needs, even if the mother goes short. And any nursing mother will tell you that the cravings if you are going short are astonishing.

But breastmilk is a high fat food, so a high fat diet like Atkins is actually ideal. Trying to combine low fat with breastfeeding tends to result in binges and pig-outs.
