Is Keto Safe While Breastfeeding

When it comes to breastfeeding, your baby’s health and nourishment are your top priorities. But what about your own dietary choices? As a breastfeeding mother, you may be wondering if it’s safe to follow the popular keto diet.

The keto diet involves consuming low-carb, high-fat foods, which can put your body into a state of ketosis. While there is no evidence to suggest that a low-carb diet directly affects breast milk supply, it’s important to consider the potential risks and benefits.

In this article, we’ll explore why it’s generally recommended to avoid the keto diet while breastfeeding, and what the best diet options are for you and your baby’s overall health.

Is the Keto Diet Safe While Breastfeeding?


When it comes to breastfeeding, ensuring the health and well-being of your baby is of utmost importance. You want to provide them with all the nourishment they need for optimal growth and development.

One diet that has gained popularity in recent years is the ketogenic diet, or keto diet for short. But is keto safe while breastfeeding? In this article, we will explore the potential risks and effects of the keto diet on breastfeeding, as well as discuss the best diet for breastfeeding moms.

Understanding the Keto Diet

The ketogenic diet is a low-carb, high-fat diet that aims to put your body into a state of ketosis. Ketosis is a metabolic state in which your body uses fat stores for energy instead of glucose.

This is achieved by significantly reducing your carbohydrate intake and increasing your fat consumption. Foods commonly consumed on the keto diet include meat, fatty fish, cheese, butter, and eggs, while alcohol, sugary foods, grains, fruit, and unhealthy fats are usually avoided.

Potential Risks of the Keto Diet While Breastfeeding

One potential risk of following the keto diet while breastfeeding is its impact on milk supply. While there is no direct evidence linking a low-carb diet to a decrease in milk supply, many pediatricians recommend a balanced diet to ensure optimal milk production.

Additionally, the filling nature of keto foods may lead to decreased food intake, resulting in a lower calorie intake and potentially affecting milk supply. Staying hydrated is also crucial while following a keto diet, as dehydration can lead to decreased milk production.

Effect on Milk Supply

Maintaining an adequate milk supply is essential for breastfeeding moms. While there is no conclusive evidence that the keto diet directly affects milk supply, it is important to be mindful of your calorie intake and hydration status.

Since the keto diet often leads to feeling full quickly, it may be harder to consume enough calories to support both your body’s needs and milk production. Remember to listen to your body’s cues and ensure you are eating enough to sustain your milk supply.

Release of Ketones

One concern when following the keto diet while breastfeeding is the release of ketones into your bloodstream. Ketones are chemicals produced when your body lacks sufficient insulin.

In some cases, high levels of ketones can lead to serious health issues such as ketoacidosis. While this condition is more commonly associated with diabetes, it can also occur due to factors such as starvation, alcohol consumption, and certain medications.

Therefore, it is crucial to be cautious and monitor your ketone levels if you choose to follow the keto diet while breastfeeding.

Side Effects of the Keto Diet

Like any diet, the keto diet has its potential side effects. Some common side effects include fatigue, muscle loss, bad breath, smelly urine, and digestive issues.

While these side effects may not directly impact breastfeeding, they can affect your overall well-being and make it more challenging to care for your baby. It is important to listen to your body and consult with a healthcare professional if you experience any concerning symptoms while following the keto diet.

Ketoacidosis and Breastfeeding

Ketoacidosis is a condition that is rare in humans but has been reported in breastfeeding women following a low-carb diet. This condition is characterized by an imbalance in the body’s metabolic processes, leading to the production of excessive ketones.

While ketoacidosis is more commonly associated with diabetes, it is essential to be aware of the potential risks and seek medical attention if you experience symptoms such as extreme fatigue, excessive thirst, frequent urination, confusion, or fruity-smelling breath.

Best Diet for Breastfeeding Moms

While the keto diet has its set of benefits, it may not be the ideal diet for breastfeeding moms. During this time, it is crucial to focus on consuming a balanced diet that meets both your nutritional needs and the needs of your growing baby. Include a variety of foods in your diet, such as whole grains, fruits, vegetables, lean proteins, and healthy fats. Adequate hydration is also vital, so remember to drink enough water throughout the day.

The Importance of a Balanced Diet

Eating a balanced diet while breastfeeding not only ensures that you and your baby receive the necessary nutrients, but it also helps maintain a stable milk supply. Your body goes through significant changes during breastfeeding, and it requires additional calories and nutrients to support both you and your baby.

By prioritizing a balanced diet, you can provide your body with the fuel it needs to produce quality breast milk and support optimal growth and development for your baby.


In conclusion, while the keto diet may have its benefits, it is advisable for breastfeeding moms to prioritize a balanced diet that provides all essential nutrients. While there is no direct evidence to suggest that the keto diet is unsafe for breastfeeding, its potential risks and side effects warrant caution.

Focus on listening to your body, staying hydrated, and consuming a variety of nutrient-dense foods to ensure both you and your baby are healthy and thriving. Always consult with a healthcare professional before making any significant dietary changes during breastfeeding.
