Congratulations, new mom. While embarking on this phase as a mom, it’s only necessary to consider the perfect way to nurture your baby. A key aspect that plays a significant role in that is your calorie intake. You want to be sure that you are taking the right amount of calories for your baby’s needs and yours and maybe still maintaining the perfect body you want. 

Well, we’re here to assist with your calorie intake as a breastfeeding mother. Finding the perfect balance has always varied based on weight, height, and even age and so to avoid insufficiency in milk production or nutrients, we present the ‘calorie intake of breastfeeding mothers calculator’. The goal here is to enable you to consume the right amount of calories daily. 

What is the Calorie Intake of Breastfeeding Mothers Calculator?

The Calorie Intake of Breastfeeding Mother calculator helps you determine how many calories you should take per day as a lactating mother. It uses your weight, age, breastfeeding frequency, height, and physical activity level to determine how many calories you should take daily.

Formulas Used for the Calorie Intake of Breastfeeding Mothers Calculator

Sourced from My Plate by the United States Department of Agriculture, the calorie intake of breastfeeding mothers’ calculator was designed based on the most recent dietary guidelines for Americans 2020-2025. 

These guidelines are carefully developed by nutrition experts and professionals to ensure accurate and reliable information to support the health of breastfeeding mothers and their babies. 

Going through them, we believe these recommendations are appropriate in use to estimate the daily calorie intake for you as a breastfeeding mother. As we’ve earlier said, there are key factors that contribute to your daily calorie intake and these recommendations reflect such belief. 

Here’s an overview:

  • Calorie intake is calculated based on body weight to achieve a healthy body mass index.
  • The height is also used. 
  • Activity Level
  • Weight growth recommendations are lower for overweight or obese women, which could decrease calorie intake. 

With such in mind, let’s see how you can make use of the calculator. 

Dietary Guidelines for Americans for Breastfeeding Moms (2020-2025)

Calorie Intake for the First 6 Months of Breastfeeding

According to the guideline in the first 6 months of lactation, a mother should take an additional 330 calories daily. This is in addition to their normal daily calorie intake.

To calculate the EER (Estimated Energy Requirement) for the first 6 months of breastfeeding, you take your pre-pregnancy calorie needs and add 500 calories per day. This accounts for the extra energy required for milk production during this period. Then, to consider weight loss in the first 6 months after giving birth, you subtract 170 calories per day from the total.

That was how the additional 330 calories earlier mentioned was derived (500-170).

Calorie Intake for the Next 6 Months of Breastfeeding (7 months – 1 Year)

When your baby is 7 months, old you will need an extra 400 calories added to your daily calories.

In other words, for the second 6 months of breastfeeding, you take your pre-pregnancy calorie needs and add 400 calories per day. This covers the extra energy necessary for milk production during this period. After 6 months postpartum, it’s assumed that your weight remains stable.

Note: These estimates are for women who had a healthy weight before getting pregnant. If a woman was overweight or obese before pregnancy, it’s best for her to talk to her healthcare provider to get advice on the right amount of calories she should consume during pregnancy and breastfeeding.

Estimates are based on Estimated Energy Requirements (EER) set by the Institute of Medicine. Source: Institute of Medicine. Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat, Fatty Acids, Cholesterol, Protein, and Amino Acids. Washington, DC: The National Academies Press; 2005.

Estimated Change in Calorie Needs During Pregnancy and Lactation for Women With a Healthy Prepregnancy Weight

The dietary guidelines for Americans recommend that breastfeeding mothers should follow the calorie intake stated in the table below.

Pregnancy: 1st trimester+ 0 calories
Pregnancy: 2nd trimester+ 340 calories
Pregnancy: 3rd trimester+ 452 calories

Do mothers need more calories while breastfeeding?

Absolutely, mothers do need more calories while breastfeeding! Breastfeeding is a physically demanding process that requires additional energy to support both the mother’s body and the production of breast milk for the baby. As a result, the caloric needs of breastfeeding mothers are higher than those of non-breastfeeding women.

Centers for Disease Control and Prevention says a breastfeeding mother might need an addition of 330 to 400 kilocalories per day. This sums it up to mean, you need more calories for milk production, energy burns, and nutrients generally. 

You can find out the amount of daily calorie intake you need by using the calorie intake of breastfeeding mothers calculator above. 

Your Calories, Your Needs

It can’t be overemphasized that you need to pay close attention to your calorie intake as a breastfeeding mother. However, do not just pay close attention to your needs, but also pay attention to your body. Prioritize nutrient-dense foods such as fruits, vegetables, healthy fats, proteins, and many more. They can help meet your caloric requirements and are also very beneficial to your body. For any other health-specific concerns, we advise you to visit your doctor.
