When it comes to new mothers, there's often curiosity about whether the process of breastfeeding or pumping can help with weight loss. After all, many mothers are looking to shed the extra weight gained during pregnancy. In this blog post, we’ll explore how breast pumping works, whether it burns calories, and how it compares to breastfeeding. We’ll also discuss factors that influence calorie burn while pumping and share tips for maximizing the calorie-burning potential of your pumping sessions.

Does Breast Pumping Burn Calories?

How Many Calories Are in Breast Milk?

First, it’s important to understand how much energy is in breast milk. On average, breast milk contains about 20 calories per ounce. This number can vary slightly depending on factors like the mother’s diet and the composition of her milk, but it’s a good baseline to consider.

When you pump milk, you’re essentially mimicking the process of breastfeeding, and the body works to produce that milk. This energy expenditure is part of why breastfeeding or pumping can burn calories. The process of lactation requires energy, and your body uses calories to produce milk, even when you're pumping instead of nursing directly.

The Calorie Burn of Pumping

Breast pumping does indeed burn calories, but not in the same way as cardiovascular activities like running or cycling. The amount of calories burned during pumping is mainly due to the energy your body uses to express milk. While it's not a high-intensity exercise, pumping still requires some effort from your body.

On average, a pumping session can burn anywhere from 100 to 200 calories per session, depending on the factors involved (which we will discuss below). The amount of calories burned will vary from person to person, but it’s important to note that while pumping does contribute to calorie burn, it’s not a substitute for regular physical activity.

Why It Burns Calories

Pumping burns calories because your body is producing and expressing milk, which requires energy. The process of lactation involves several physiological changes in your body. Your body needs energy to produce milk, regulate your hormone levels, and support the milk ejection reflex (let-down). These processes consume energy, which translates into calorie burn. The longer and more frequently you pump, the more calories you may burn.

Factors That Influence Calorie Burn While Pumping

There are several factors that can impact how many calories you burn while pumping. Here are the most important ones:

Pumping Duration

The longer you pump, the more calories you will burn. On average, pumping sessions last anywhere from 15 to 30 minutes. However, if you pump for longer periods, your body will naturally burn more calories. Keep in mind that prolonged pumping sessions may not always be necessary for milk production, so it’s important to strike a balance between effective milk expression and efficiency.

Frequency of Pumping Sessions

The more frequently you pump, the more calories you burn. Mothers who pump frequently throughout the day, especially those who pump exclusively, are likely to burn more calories than those who pump just once or twice. Consistency is key in maximizing the calorie burn from pumping sessions. For high-frequency pumping, an electric breast pump like the MomMed S10 Pro electric breast pump, with its large battery capacity and long-lasting battery life, is ideal. Its durability and extended battery life make it a great choice for moms who need to pump multiple times a day without worrying about running out of power.

Breast Size and Milk Supply

Breast size and milk supply can also influence calorie burn while pumping. Larger breasts may store more milk, which means there may be more milk to express during each session, requiring more energy to empty them. On the other hand, mothers with smaller milk supplies may have less milk to pump, which could result in slightly fewer calories burned. Additionally, mothers with a higher milk supply may have more frequent let-downs, which can also increase calorie burn during pumping sessions.

Pumping Efficiency

The efficiency of your pump can have a significant impact on how many calories you burn. An efficient breast pump can express more milk in a shorter amount of time, which means you’ll burn more calories during each session. The MomMed S21 wearable breast pump, for example, is designed with high efficiency in mind. It has three different modes and 12 adjustable levels to ensure effective and comfortable pumping. An efficient pump can help you empty both breasts simultaneously, saving time and ensuring a more effective session, which ultimately supports your calorie-burning goals.

Comparison Between Breastfeeding and Pumping for Calorie Burn

Breastfeeding vs. Pumping

While both breastfeeding and pumping burn calories, there are some key differences between the two. Breastfeeding tends to burn more calories than pumping because it requires more physical effort. When you breastfeed directly, your body engages in physical processes such as holding the baby, positioning, and stimulating the milk flow. The baby also exerts suction while nursing, which involves additional muscle movements from the mother’s body.

Pumping, on the other hand, is a more passive process. You simply sit down and attach the pump to your breasts, which doesn’t require the same level of physical engagement. While pumping can still burn calories, it generally doesn’t burn as many as breastfeeding does.

The Role of Physical Activity

It’s important to remember that pumping alone won’t replace regular physical activity if weight loss is your goal. Pumping burns calories, but it is not a form of aerobic exercise. Combining pumping with regular physical activity, like walking, yoga, or light cardio, can help accelerate your postpartum weight loss.

Impact on Weight Loss

For mothers who are breastfeeding or pumping, losing weight gradually is a common goal. Since both breastfeeding and pumping burn calories, they can contribute to weight loss over time. However, it’s important to approach weight loss with balance, as extreme dieting or over-exercising can affect your milk supply. The best approach is to maintain a healthy diet, stay hydrated, and engage in light physical activity to support overall well-being.

Maximizing Calorie Burn While Pumping

If you’re looking to maximize the calorie burn while pumping, there are several ways to optimize your routine and lifestyle. While pumping itself can burn a significant number of calories, combining it with other healthy habits can enhance the process and help you achieve your postpartum fitness goals.

Combine Pumping with Physical Activity

Pumping while on the move can be a great way to increase calorie burn. Consider incorporating light physical activity into your routine while you pump, such as walking, doing light stretches, or even some light exercises. Although pumping is a sedentary activity, staying active during your pumping sessions can help you burn more calories without adding extra time to your day. Even something as simple as walking around while pumping can make a difference.

Maintain a Healthy Diet

Fueling your body with a balanced diet is essential when trying to maximize calorie burn. Eating a nutrient-dense diet that includes lean proteins, healthy fats, and plenty of fruits and vegetables can help you stay energized, support milk production, and maintain your metabolism. While pumping can help burn calories, eating properly will ensure that you have the energy you need to power through your day and maximize the effectiveness of your routine.

Hydration and Rest

Staying hydrated is another important factor when trying to burn calories while pumping. Water is essential for milk production, so drinking plenty of fluids helps with both your calorie-burning goals and maintaining a healthy milk supply. Also, adequate rest is vital to keep your energy levels up. While it may be difficult to prioritize sleep with a newborn, making an effort to rest when you can helps your body recover and function optimally.

FAQs About Calorie Burn and Pumping

Can Pumping Help with Postpartum Weight Loss?

Yes, pumping can contribute to postpartum weight loss by burning calories. However, it’s not a substitute for regular physical activity or a healthy diet. Pumping alone may not result in significant weight loss, but when combined with other healthy habits, it can support your weight loss journey.

How Many Calories Does Pumping Burn Per Day?

The number of calories burned from pumping varies depending on the frequency and duration of your pumping sessions. On average, mothers burn about 100 to 200 calories per pumping session. If you pump multiple times a day, this can add up to a significant number of calories burned each day.

Does Pumping Affect Milk Supply or Calorie Burn?

Pumping itself does not directly affect your calorie burn, but it may influence your milk supply. Efficient pumping helps maintain or even increase milk production, which in turn supports your body’s energy expenditure. If pumping sessions are not frequent or efficient, it could affect your milk supply, and in turn, your calorie burn may be less. Be sure to use an effective pump like the MomMed S21 double wearable pump to optimize your milk expression.

Conclusion

Pumping breast milk can indeed burn calories, though it’s not as intense as other forms of exercise.
