A new study from Johns Hopkins University finds that eating a high fat diet when nursing may lead to an overweight baby and potential health problems, like diabetes, later on.  The research, done on rats, is preliminary, however, knowing that breastmilk composition varies based on the mom’s diet, it seems feasible that too much fat would impact baby’s weight. Interestingly, the researchers found that the diet during nursing made more of a difference on the baby’s weight than the diet during pregnancy. Bottomline: Eating a high fat diet isn’t good for you or your weight loss efforts anyway. So, if you’re nursing, stick to a healthy, well balanced diet, like the one we recommend in The Baby Fat Diet. You’ll get leaner and your baby will be healthier for it.
