Burn Fat: Taking Keto Diet while Breastfeeding? Yay or Nay?


Keto Diet, full name ketogenic diet is a high-fat low-carb diet that forces your body to burn fat rather than carbs.

Burns Fat Instead of Sugar 

Many people got into Keto diet as they heard it forces your body to burn fat, is it true? 

Yes, the Ketogenic diet makes your body burn fat instead of burning sugar/ carbs. It relies on fueling ketone bodies which are created by your liver, ketone bodies then become the replacement of sugar as the source of energy in your body. 

Keto Diet Risks

We are not going deep into what keto diet recipe, meal plans or the amount of fat or carbs you should consume each day. But to keep in mind, sources of carbs include - fruits and veggies. There are restrictions on the type and amount of fruits and vegetables if you’re following the Keto Diet. 


When not handled properly, the rise of ketone bodies can lead to ketoacidosis that lowers your blood pH level and requires immediate medical treatment. 


Since you’re cutting on foods that are rich in fibre - rice, grains, starchy veggies, etc.
