Is it safe to fast while breastfeeding? Breastfeeding bumps up your nutritional needs even more than pregnancy. Nursing moms should take in around 450 to 500 extra calories per day — which can be tough to do while fasting. Ultimately, you'll feel your best and protect your supply by avoiding fasting altogether.

Should a breastfeeding mother fast?

Breastfeeding research tells us that short-term fasting (not eating) will not decrease milk supply, but that severe dehydration can decrease milk supply. Fasting does affect the biochemical/nutrient content of breastmilk to a certain extent.

Can skipping meals affect breast milk?

Don't skip meals while breastfeeding, even if you're trying to lose weight. Skipping meals can slow down your metabolism and cause your energy to drop, which can make it more difficult to be active and care for your baby.
