Is It Safe to Follow Intermittent Fasting While Breast-Feeding?

Following intermittent fasting during pregnancy and breastfeeding is generally not recommended. Eating nutrient-dense food that contains whole grains, fruits, and vegetables, is essential while breastfeeding.

After starting the baby’s supplement food, you would require around 300-600 calories per day to supplement milk production.

Few studies were conducted to evaluate human milk composition during fasting. Acute and chronic repetitive fasting, both types of fasting were studied. The results indicated that there were no clinically significant changes in macronutrients in breast milk during acute fasting. However, the study does not mention any changes in micronutrient composition. 

Including large amounts of proteins, iron, and calcium in your diet can enhance milk production and provide enough nourishment to the baby. Experts advise not to follow any fasting diets while your baby is completely dependent on breast milk. Once your baby is 6 months and above and started with food supplements, you may consider following less restrictive diet strategies.

How Fasting Affects Milk Supply?

The concept of fasting is not entirely a new one; during Ramadan, many breastfeeding mothers fast. According to a Turkish study, mothers of children 6 months and above reported that there was a reduced milk supply while fasting. Some mothers also have said they started giving more semi-solid foods during fasting. 

Experts suggest that a low supply of lactation might be due to a lack of macro and micronutrients to support milk production. Currently, there are no long-term studies linked with intermittent fasting and breastfeeding. 

Some experts suggest that fasting once or twice a week does not impact milk supply or child health and growth much. Mothers should increase their fluid intake before they start the fast. They can consider eating foods that promote milk supply, such as meat, chicken, garlic, oat milk, papaya, eggs, and green veggies.

In fact, most of the foods that are linked with an increase in breast milk are of low calories and are rich in vitamins, proteins, and calcium. Hence, during your fasting days, you can plan your diet with foods that enhance your milk supply. 

Before you start any diet plans talk to your doctor; do not try highly restrictive diets as your body can’t support it.

Which type of Intermittent Fasting can be Considered Safe?

Generally, intermittent fasting is not recommended while breastfeeding. But, if your baby is 6 months and above and is not totally dependent on breastmilk, you may try a less restrictive type of intermittent fasting. 

You can consider 5:2 intermittent fasting; in this method, you are fasting only for 2 days and are on a normal diet for the rest of the 5 days. During your fasting days, you can have some calories; if you are a breastfeeding mother, you can consider having 300-600 calories. You can choose Monday and Friday as your fasting days in a week: do not fast on consecutive days.

Fasting for short periods like following overnight fast or 12/12 fasting does not affect your milk supply. Your body can continue to supply milk even if you are taking little or no calories. Fasting for longer periods or a restricted diet may not affect your milk supply, but it may have an impact on the nutritional quality of your breast milk. Make sure to provide nutrient-rich supplemental food to your baby to avoid any deficiency.

Choose an intermittent fasting type that is very convenient for you. You will require a lot of energy to take care of your baby. Hence, fewer calories, low nutritional food may diminish your energy level and health.
