check_icon Research-backed

Most lactating mothers worry about the increased possibilities of weight gain after breastfeeding. This is because lactationiXProcess of secretion and feeding of breastmilk after childbirth assists in postpartum weight loss. During exclusive nursing (the first six months), you may consume an excess of about 400-500 kilocalories per 24 hours for milk production (1). However, the process of breastfeeding affects the metabolism, due to which you may end up losing some weight.

In this post, we discuss the effects of lactation and its link with maternal weight gain. While on the topic, note that dieting is not recommended during lactation as it may comprise the nutritional needs of the mother and the baby.

Will You Gain Weight Once You Stop Nursing?

There is no substantial research-based evidence that links weaningiXProcess of transitioning a baby’s diet from breastmilk or formula to solids and other liquids and weight gain. It is true that breastfeeding burns more calories and also makes metabolism more efficient (2). However, the likelihood of weight gain after cessation of breastfeeding could vary from one woman to another. While some women gain weight after they wean their babies, it does not happen with all women.

What Causes Weight Gain After Weaning The Baby?

Some women may notice weight gain after they wean their baby.

Trista Best, a registered dietitian from Dalton, Georgia, says, “When moms begin weaning their breastfed babies, the extra calorie need decreases. However, sometimes, moms will experience weight gain after weaning their baby and no longer making breast milk. This can have two causes: hormones and overeating on calories. A breastfeeding and weaning mom’s hormones are changing daily, which can cause the body to hold on to more weight. The weaning mother may also continue to eat the same calories that she ate while breastfeeding out of habit. This can cause weight gain.”

The weight gain may occur due to the following causes.

1. Caloric surplus

The caloric surplus may cause weight gain after breastfeeding.

Breastfeeding mothers need more calories to meet their requirements for nutrition and breast milk production (3). Thus, your appetite may increase during breastfeeding, and it may stay that way for a while even after you wean your baby. The excess calories may eventually lead to weight gain. The effects of caloric surplus could be compounded by a lack of physical activity and a sedentary lifestyle.

2. Hormonal changes

Prolactin and oxytociniXA hormone that stimulates let down of the accumulated milk while nursing are hormones that play a significant role in breastmilk production. Once you stop breastfeeding, these hormones begin to drop. Both oxytocin and prolactin play an essential role in your emotional wellness. Some women may experience depression or feel low, causing them to binge eat, which could cause weight gain (4).

Elliot Reimers, a NASM-certified nutrition coach, explains, “Mothers experience hormonal changes after weaning, which can make them feel down. Weaning also makes them feel that they have lost connection with their child now that the child is growing up and ‘no longer needs her.’ When they feel negative emotions, some mothers turn to stress eating, leading to weight gain.”

It may take as long as six months for your hormones to return to pre-pregnancy level after stopping breastfeeding (6).

Tips To Avoid Weight Gain After Weaning

Dr. Brittany Robles, a New York-basedOB/Gyn and NASM-certified professional trainer, says, “Once you stop breastfeeding, it is important to decrease your food intake a bit to compensate for the drop in your body’s energy requirement. It doesn’t have to be all at once. You can do this by gradually decreasing your serving sizes. Don’t eliminate foods, just eat a slightly smaller portion. Over time, your hunger and appetite will adjust to the change in caloric intake.”

The following tips could help you manage your food intake to shed the extra weight you gained after weaning your baby.
