Why you’re always hungry while breastfeeding?

what to eat after child birth

You were warned about the sleepless nights, but no one told you about the round-the-clock hunger and thirst that comes with breastfeeding. The good news is, that there are plenty of ways to safely curb your breastfeeding hunger, while not impacting your milk supply.

Why do I feel so hungry whiile breastfeeding?

Breastfeeding requires energy, and our bodies need to burn calories to create this energy. The extra energy used each day to create milk is around 500 calories and can be even higher during the first few weeks. In addition to this sustained energy use, most mothers are tired and suffering from sleep deprivation. When we're in an overtired state, it often causes a desire to comfort eat, and high-sugar, high-carb foods are usually the go-to in these cases. 

Other reasons you are always hungry while breastfeeding

1. Skipping meals 

A new mum is undoubtedly in the running to be one of the busiest people in the world. Not only are you exhausted and depleted after having just given birth, but now you also get woken up every couple of hours to feed, burp, change and settle your little one. 

With a schedule like this, it's understandable that many mums either forget to eat or don't get a chance sometimes. However, skipping meals can lead to a dangerous level of hunger, and therefore accessible, convenient, one-handed snacks are your best friend in the first few weeks; they'll get you through to the next meal if you find yourself caught up. 

2. Not eating enough protein 

Protein requirements increase after birth for two reasons: to assist the mother in her recovery and support healthy growth in the baby. Getting adequate protein post-childbirth is one of the most powerful ways to support recovery and keep all cells in mum and bub happy and healthy. 

A high-protein diet is the most satiating diet of all. Protein not only helps to keep you full, but it also increases the secretion of the appetite and hunger-reducing hormones. Your body craves protein, so if you're not consuming enough, hormones will create hunger signals, encouraging your body to eat something and restore the protein. Eating enough protein is how you can manage your breastfeeding hunger without overeating.

3. Not drinking enough water 

Mild dehydration is one of the leading causes of overeating. This is because your body thinks it needs food when really, it's looking to be hydrated. Why? Because the section of the brain called the hypothalamus is responsible for regulating both appetite and thirst. So as we start to become dehydrated, our default is often to go for food rather than water. 

The solution? Stay ahead of your hydration. Even if coffee is the first thing on your mind when you open your eyes, first have a large glass of water. Other tips to help with water intake: 

  • Buy a reusable water bottle that you like and keep it on you, always. Pro-tip for breastfeeding mums; get a bottle that has a straw rather than a lid. Taking a cap off one-handed is difficult, whereas a pop-up straw is simple. 
  • Rehydrate every time you feed, even during the night feeds. 
  • It doesn't just have to be plain water; try mineral water, adding a slice of lemon or some mixed berries. Or, if you're really not a water lover, herbal teas are a great option. 

4. Not eating enough fibre 

Dietary fibre is super important for post-partum women. Fibre is what keeps everything running smoothly in our digestive systems, and if we're not consuming enough, it can lead to constipation. If there's one thing a post-partum mum wants to avoid, it's having to push when going to the toilet! 

There are two types of fibre, and you want to begin incorporating both into your diet. Insoluble fibre is the type that speeds up the digestive process and moves things along. Whereas insoluble is the type that adds bulk to the foods you've eaten and helps to keep you feeling full. So, if your diet lacks fibre, increased hunger is often one of the first things you'll notice. 

High fibre foods for breastfeeding women include: 

  • Lentils and beans (chickpeas, kidney beans etc.)
  • Vegetables, in particular broccoli, carrots, and Brussel sprouts 
  • Fruits, including avocado, berries, apples, pears, and kiwi fruit 
  • Dried fruits
  • Oats
  • Chia seeds 

5. Bub is going through a growth phase

If bub is going through a growth spurt or cluster feeding, chances are you're going to be extra hungry. So the most important thing to do during these times is to honour your hunger and fuel your body with nutrient-dense, satisfying and satiating foods.  

Remind yourself that your number one job is to support your little one's needs. If you're not eating enough or missing out on essential nutrients due to skipped meals, it's going to cause issues for you and your bub. So surround yourself with nutritious one-handed snacks and be sure to have some prepped for the night-time.

How to curb hunger while breastfeeding

1. Eat regularly

Fuelling your body regularly and consistently is key. Our advice is to set reminders on your phone to prompt you to grab a snack, make a smoothie or have some lunch. New mums have a million things on their minds, so simplifying things where we can is vital. 

2. Limit sugar intake 

When we are overtired, we see a spike in cortisol levels, which tells our body we are under stress. So our body thinks we need to fuel it with high-energy foods to deal with this extra stress. And this leads to cravings for high-sugar treats and comfort-eating. 

When women give in to these cravings, they will often choose an unhealthy option instead of a healthy option. So not only are we getting the negative impact of unhealthy food, but we're also missing out on potential nutrients from healthy foods. 

If it's something sugary you're craving, instead go for something with natural sugar like fruit or something sweet that's sugar-free like an In Shape Mummy hot chocolate or chai.   

3. Focus on nutrients, not calories

We recommended aiming for wholesome foods 90% of the time and treats 10% of the time. You want every meal to contain a healthy amount of carbs, fats, protein, and as many colourful vegetables as possible. A simple method to follow is to fill half your plate with vegetables, half a cup of cooked carbs and a piece of protein that fits in the palm of your hand. 

4. Eat more protein.

Delicious high-protein foods for breastfeeding include: 

  • Eggs
  • Oily fish like salmon and tuna 
  • Lean meats and chicken 
  • Nuts 
  • Greek yogurt 
  • Oats 
  • Quinoa 
  • In Shape Mummy Health Shake (a protein-enhanced meal replacement shake designed specifically for breastfeeding mums)

How much should a breastfeeding mum eat?

Most healthy breastfeeding women maintain an abundant milk supply while taking in between 1800-2200 calories per day. However, there is no one size fits all figure as it depends on your BMI. Your BMI (body mass index)is calculated based on your age, weight, height, whether you are breastfeeding partially or exclusively and how much activity you do. Cick here to see how many calories you need to get in shape while breastfeeding here.

Should I eat at night while breastfeeding?

During the first few weeks, you may find you need to snack during the night-time feeds. Eight-ten hours is a long time to go without fuelling your body if you’re up multiple times and burning energy while you feed. 

Bananas are an excellent night-time snack as they are high in potassium which promotes good sleep.

It has literally boosted my milk supply. I used to pump 160mls and now I average 240mls .. I've never been able to get that."

"I've lost 35 kgs thanks to the In Shape Mummy Health Shakes. 110 kgs to 75 kgs! Juggling two little boys under 2 years old doesn't leave much time for healthy choices for Mummy and the In Shape Mummy Health Shake is such an easy solution to get all the goodness I need to keep going! My older son is 20 months and I didn't get the chance to lose the weight gained whilst carrying him before I was pregnant again with baby #2. I easily gained 40kgs across the two pregnancies and no thanks to terrible pelvic pain in pregnancy #2 wasn't able to keep active. Now that my second son is here and the pelvic pain has gone I have stuck to replacing breakfast with my shake and walking every morning for the duration of the morning sleep. Some days I will do a second shorter walk during his nap. I'm still able to enjoy yummy healthy foods and definitely do not feel like I'm going without. I no longer crave sugary foods as the shake sets me up for the day with its magical satisfying ingredients! The shake has become even more of a must since returning to work! If I thought I was busy before, life just got a whole lot busier! Now that I've lost the weight, I have more energy, zero aches and pains and have a better mood. I tell all my friends about In Shape Mummy because easy weight loss doesn't need to be a secret! Xx"

"I discovered In Shape Mummy Health Shakes not long after my second baby was born. He has an intolerance to dairy so I was looking to find something that was safe for breastfeeding, and also vegan friendly. I have recently started a detox program with the help of a naturopath. She was so impressed with the ingredients that she has encouraged me to continue having it! In Shape Mummy has not only helped me lose the 26 kgs I put on in pregnancy, but it’s helped me nourish my body when I’ve been time poor and sleep deprived. It’s the only shake that I actually enjoy the taste of! My breakfast everyday includes ice, almond milk, water, a banana and my In Shape Mummy (my current fave is the caramel fudge!). At 11 months postpartum I feel great! And my breastfeeding journey is still going strong - my milk is in perfect supply for what Bub needs. I cannot recommend In Shape Mummy Health Shakes more highly!”
