Just like "drinking to thirst", you should "eat to hunger" while nursing. Studies have shown that most nursing mothers tend to lose up to one and a half pounds a month for the first 4-6 months after giving birth, and continue to lose weight at a slower rate beyond that time. They tend to lose more weight than formula feeding moms who take in fewer calories. If you want to lose weight (and most of us do - how depressing to still be wearing those old maternity clothes we got so sick of after the baby is born
) plan to do so slowly. It's best not to try to aggressively lose weight during the first couple of months after birth, because during that time your body needs to recover from childbirth and establish a good milk supply. Losing weight too quickly (more than one to one and one half pounds per week) has been associated with the release of environmental contaminants stored in body fat into the milk.
