Eating Enough While Breastfeeding

You're up at night, feeding all day, and starving, and also feeling pressure to "bounce back" fast. If you've been skipping meals or cutting back because you're busy or trying to lose the baby weight, this one's for you.

Making milk is real work. Your body needs fuel to do it, and so do you.

How Much Extra Are We Talking?

Estimates suggest exclusive breastfeeding adds roughly 330 extra calories a day in the first six months and a bit more after that, compared with your needs before pregnancy (Butte & King, 2005, Public Health Nutrition). That's less than most people expect, about a hearty snack or small meal, but it's on top of your baseline needs, and it's easy to miss when you're too busy to eat.

Protein and Key Nutrients Matter More Too

Protein needs go up during lactation, with recommendations around 1.3 g/kg a day, about 71 g for most women (Institute of Medicine, 2005). Some nutrients in your milk, including iodine, choline, B12, and DHA, depend partly on what you eat, and your own stores can get depleted if intake is low. Ask your provider whether a prenatal or postnatal vitamin makes sense for you.

What Happens If You Under-Eat?

Your body prioritizes milk production, so mild under-eating doesn't usually shut it off overnight. But it can leave you more exhausted, more depleted, and slower to recover, which matters when you're already running on little sleep. (We wrote about why the exhaustion runs deeper than sleep in Why You're Always Exhausted as a Mom.) Research on gradual weight loss in breastfeeding women found that losing about half a kilogram a week didn't affect infant growth (Lovelady et al., 2000, New England Journal of Medicine). Very aggressive restriction is a different story, and it's not worth the cost to your energy and mood.

Water and Practical Fuel

Many women feel thirstier while nursing. Keep water within reach of wherever you feed. For food, think easy and repeatable: eggs, yogurt, nuts, fruit, rice and viands you can reheat, oats, canned fish, a handful of whatever protein is on hand. Eat before you're starving, and a snack by the nursing chair beats good intentions.

Personal note for those who crave sugar after a feed: this was me when I was exclusively breastfeeding Erica. Dark chocolate (65% or higher please! Sugar-free option is a plus) is a good source of antioxidants, and a square or two really hits that post-feed hunger spot.

Gentle Note on Body Goals

If you want to lose weight, there's room to do it the right way, and with the proper fuel for your body and milk production. Please note that this isn't the season for aggressive dieting. Your body just did something huge and is doing something huge every day.

You aren't "eating too much" or "being lazy" by feeding yourself properly. You're fueling a full-time job. And if you've been calling yourself lazy lately, read You're Not Lazy. You're Running on Empty.
