Breastfeeding and weight loss: the complete physiological guide

Many new mothers wonder about weight management during the postpartum period. Between social pressures to get your "old body" back and the physiological reality of your body that has just given birth, it is crucial to understand how it all really works.

At 23 Mai Paris, we support mothers in all aspects of motherhood, including issues related to the body and well-being. In this article, we take an in-depth look at the links between breastfeeding, metabolism, and body shape after childbirth, with kindness and without judgment.

The production of breast milk is an extremely energy-intensive biological process. It is estimated that in order to produce the milk needed for an infant's growth, the body must mobilize between 500 and 700 additional calories per day.

This significant energy expenditure explains why many studies suggest that breastfeeding women lose weight faster than women who use commercial formulas.

In practical terms, this means that your body is working hard, even when you are sitting down breastfeeding your baby. It is an invisible but very real effort.

During pregnancy, the body naturally stores reserve fat, mainly in the hips and thighs. These reserves are not a "flaw": they are specifically intended to serve as fuel for breastfeeding.

During breastfeeding, the release ofoxytocin and prolactin not only promotes milk ejection:

• Oxytocin helps the uterus contract and return to its pre-pregnancy size.
• These hormones also influence how lipids are metabolized.

That's why breastfeeding can contribute to gradual, natural weight loss without any particular effort.

There is a common paradox: despite high calorie expenditure, weight can stagnate or even increase. It is not a question of willpower or failure. Several physiological factors explain this phenomenon:

1. Lack of sleep

Fatigue increases levels of cortisol, the stress hormone, which promotes fat storage, particularly in the abdominal area. And let's be honest: with a newborn, sleep is often the first thing to go.

2. Intense hunger

The body naturally demands more food to compensate for the energy lost during milk production. This hunger is real and legitimate. However, it can lead to a higher calorie intake than expenditure if you eat quickly or without paying attention.

3. Water retention

Postpartum hormonal fluctuations can cause temporary swelling that masks fat loss on the scale. Don't rely solely on the numbers.

4. Stress and mental load

Becoming a mother is an emotional upheaval. Chronic stress directly affects metabolism and can slow down weight loss.

It is not a question of following a restrictive diet, which could affect the quality of the milk or lead to excessive fatigue. Here is a caring and realistic approach:

1. Choose high-quality proteins

Protein promotes satiety and preserves muscle mass. Think eggs, chicken, fish, and legumes.

2. Stay sufficiently hydrated

Water is the main component of breast milk and helps regulate appetite. Keep a water bottle handy and drink during each feeding.

To learn more about hydration, check out our article Herbal teas and plants: allies to support your breastfeeding journey.

3. Focus on complex carbohydrates

Quinoa, oats, brown rice, and sweet potatoes release energy slowly and prevent fatigue.

4. Avoid ultra-processed foods

They cause insulin spikes that are not conducive to metabolic balance and often provide empty calories.

5. Listen to your signals of fullness

Learn to distinguish between real hunger and emotional fatigue. Eating slowly and mindfully can help you better perceive these signals.

Losing weight after giving birth is a marathon, not a sprint. Your body took nine months to transform, so it's only natural to give it time to regain its balance.

Social pressure to get your "old body" back can be counterproductive and a source of suffering. Your body is not a problem to be solved: it has accomplished something extraordinary.

What really matters:

• Feel good about yourself
• Having the energy to enjoy your baby
• Take care of your mental health as well as your physical health

To learn more, read our article "Mom, but not only that": finding your place as a woman after the arrival of a baby.

Feeling good about your body also depends on how you dress during this transition. A mother who feels beautiful and comfortable in her clothes will have a more relaxed relationship with her body image.

At 23 Mai Paris, our nursing clothes are designed to accommodate changes in your figure without ever feeling restrictive. Our cuts allow for total freedom of movement, whether you're out for a brisk walk with your baby or relaxing on the sofa.

Flattering cuts for postpartum

Choose Breastfeeding dresses or Breastfeeding t-shirts with a slightly loose fit. These pieces allow you to experience your body's changes without frustration. Our invisible opening systems guarantee total discretion, reducing stress when you go out and promoting an active lifestyle.

Breastfeeding can contribute to postpartum weight loss due to the calories burned, but this is not guaranteed for everyone. Every body is different, and every story is unique.

What matters is taking good care of yourself: eating a balanced diet, resting when possible, getting emotional support, and wearing clothes that make you feel good.

At 23 Mai Paris, we believe that every mom deserves to feel beautiful and comfortable, no matter what stage of her journey she is at. Our nursing clothes are designed to accompany you with softness, comfort, and elegance.
