While following a ketogenic diet while breastfeeding is possible, it's important to approach it with some caution and consider a few factors.

Although research shows1  that a low-carb, high-fat diet such as the ketogenic diet can lead to a higher concentration of fat in breast milk (and therefore make it more filling for your baby), breastfeeding increases your susceptibility2  to ketoacidosis, where ketone levels in the blood become dangerously high. Therefore, it's crucial to stay well-hydrated, eat an adequate amount of calories and ensure a healthy balance of nutrients.

If you're keen on trying a keto diet while breastfeeding, it's highly recommended to consult with a registered dietitian or healthcare provider who specializes in maternal and infant nutrition. They can help you navigate the diet safely, ensuring you and your little one receive the nourishment you need. Remember, your well-being and that of your baby come first!
