Are you not losing weight while breastfeeding? Here's why.

Are you not losing weight?

Being a new mum and experiencing weight gain is frustrating. It's incredibly disheartening when you hear of women claiming that their mum tum melted off thanks to breastfeeding. 


The truth is neither weight gain nor weight loss can be attributed to breastfeeding alone. A range of factors are responsible for your postpartum weight, including the types of foods you're eating, the total number of calories you're consuming, as well as your age, metabolic rate, activity level and cortisol levels.  


So, if you're someone who thinks they're doing everything right but still gaining weight while breastfeeding, here are some reasons that might explain why. 


Why am I not losing weight while breastfeeding?



1. You're eating more calories than you are burning in a day. 


If you eat more calories than you burn, you will gain weight. Alternatively, you will lose weight if you burn more energy than you consume. However, if you eat too few calories, you risk slowing down your metabolism and causing harm to your body. And, if your calories are too low while breastfeeding, it can impact your milk supply. 


So, the key to losing weight is to consume nutrient-dense, healthy foods and maintain at least a moderate level of physical activity. The combination of a healthy diet and exercise should ensure your energy output is slightly less than your energy input. And this will allow you to lose weight safely and gradually without impacting your milk supply.


If you eat healthy food and avoid junk food, you will naturally lose weight. There is usually no need to count calories if you take this approach.


Although we don’t recommend strictly counting calories (as it can be stressful and exhausting), we understand that some people benefit from a guideline, particularly if you're having trouble losing weight.

The number of calories required in a day differs from person to person. There is no one size fits all. Obviously a 100kg mum has different energy requirements to a 60kg mum. And if you're breastfeeding you need additional calories to support your milk supply.


Your individual requirements are based on your age, weight, height, whether you are partially or exclusively breastfeeding and your activity level.

2. You're eating the wrong foods. 


It's important to remember that calories are not made equal. One hundred calories worth of chocolate is not equal to 100 calories worth of eggs. Chocolate is high in sugar and simple carbohydrates with little protein. It's full of empty calories that will not fill you up, which leads to overeating later on. On the other hand, eggs are high in good quality protein and are full of other nutritious vitamins and minerals to fuel your body with energy and sustain your hunger.   

We know it's hard to eat healthy when you're a breastfeeding mum. You're the busiest and most tired you've been in your entire life, so it's natural to crave high sugar foods that give you an instant energy boost. But if you commit to eating healthily 90% of the time, you won't experience rollercoaster style peaks and dips in your blood sugar levels, and you'll find your energy is much more stable. 


The In Shape Mummy Health Shake can be your saviour here because it's so quick and convenient. It's a one-handed job, can be prepared in under five minutes, will fuel your body with protein and essential vitamins and minerals, all while satisfying your sweet cravings.

3. You're not consuming enough nutrients 


Many breastfeeding women are so eager to drop the baby weight that they drastically cut their calories and even starve themselves. There are problems with this approach. First is that you will you be putting your body under extreme pressure and hindering your postpartum recovery. Second it that, it can backfire and lead to weight retention.  Third, you need to consume enough nutrients to support your baby’s growth and development.


Your body needs proteins, fats, minerals and vitamins to repair and transform postpartum. If you don’t eat enough of these vital nutrients, you will slow your recovery.


If your body doesn't get enough nutrients to support yourself and your little one, it can lead to your metabolism slowing down to conserve energy. And a slowing metabolism can reduce weight loss, and even lead to weight gain.


When you're breastfeeding, the nutrients you eat pass through your breastmilk. So, it's important to pack in as many nutrients as you can so that you and your little one can thrive. 


We're not saying you can't have treats now and then, but nutrient-dense snacks like raw nuts, eggs, tinned tuna and salmon, Greek yoghurt and fresh fruit and vegetables should be your priority.  Eating these foods will help get your baby the nutrients they need for their healthy growth and development.



4. Mindless snacking 


Having little kids means always having a supply of snacks on hand. And if you're snacking, you need to be aware of how many extra calories you're consuming. Mindless snacking or finishing off your kids' leftovers is one of the most detrimental things for losing weight. You'd be surprised at how quickly the calories add up. 


Two handfuls of Barbeque Shapes contain over 120 calories, as does an Uncle Toby's muesli bar. Three Oreo cookies are 160 calories, and a serving of potato chips is around 150 calories. So, you can see, if you have a cookie here and a handful of chips there, the calories add up super quickly. Ultimately this could be the reason why you do not see a weight shift. 


Our tip is to always have wholesome snacks on hand; it's easier to say no to something unhealthy if a healthy option is sitting right there. Vegetable sticks and hummus, boiled eggs, avocado on rice cakes, mixed nuts, bananas and smoothies are all great snack options. In Shape Mummy's Chocolate Brownie Breastfeeding Boost Bars and Salted Caramel Peanut Protein Bites are also fantastic healthy options for snack attacks.



5. Unhealthy cooking methods


The number of calories in popular cooking oils is quite shocking. Below are the total calories for 1 tbsp of the most common cooking oils:


Vegetable oil: 124

Olive oil: 119

Coconut oil: 117


It's unrealistic to cut out oil from your cooking, and it's also unnecessary. But what's important is knowing that if you're a little loose-handed with your oil, you could quickly be adding anywhere from100-300 extra calories to your meal.  


We recommend measuring your oil and reducing the amount when you can. So many recipes require copious amounts of oil, but, if you reduce the amount by ½ or 1/3 you could save yourself 200+ calories without affecting the flavour of your meal.


Even if you use healthy oil, frying will add a lot of calories to food. Instead try baking or boiling food when cooking.



6. Drinking too many calories 


Fizzy drinks and store-bought juices are an easy way to consume extra calories. A 330ml can of Coke contains a whopping 39g of sugar and 140 calories. A serving (200ml) of Golden Circle orange juice contains over 15g of sugar and 82 calories. So having one of these drinks a day will see you reach and even exceed your recommended daily sugar intake, as well as add significant calories. We all know processed sugar is the enemy to weight loss.


If you're trying to lose weight, there are lots of sugar-free delicious drink options. Sparkling water with a squeeze of fresh lemon is a great option for weight loss. Kombucha is a low sugar fizzy drink that contains probiotics that support gut health. 



Why Do I Feel So Hungry While Breastfeeding?


Producing milk requires energy, which is why you end up burning extra calories. 


If you are not eating enough healthy food to fulfil your protein and nutrient needs your body will keep craving more food. Eating junk food can lead to craving more food later on.


In addition, most breastfeeding mums are also tired and stressed, which can lead to comfort eating. 


The combination of being hungry and comfort eating could mean you see the numbers on the scales go up. When you know the chocolate is in the fridge, it’s hard to muster the energy to find something nutritious to eat. Uber Eats and Deliveroo make temptations all the more difficult to ignore. 


That’s why you need to have a plan to combat that hunger. You’ll notice a pattern to your appetite, so get out in front of it by having some boiled eggs, nuts, fruit and yoghurt on hand when it strikes. 


It is also important not to skip meals. Skipping meals can lead to being more hungry later in the day which can lead to over eating the wrong foods (it is harder to make healthy choices when you're starving hungry).


Try to aim for breakfast, lunch and dinner plus a morning and afternoon snack.


We understand it's hard to always prepare healthy food when you're so busy which is why the In Shape Mummy Health Shake can be a great help.




Will my milk dry up if I focus on weight loss?


Healthy, sustainable weight loss will not dry your milk up. As long as you're not significantly reducing your calories or creating a significant caloric deficit, your body will find more than enough nutrients to produce milk from the foods you eat and your existing fat stores. 


Weight loss isn't about feeling hungry all the time. It's about eating what you need to reach a healthy weight. If you're breastfeeding, that means eating to account for the extra energy you're burning without going overboard or devoting those extra calories to chocolate cake. 


In fact, by shifting your mindset away from how much you're eating to what you're eating, you'll actually support milk production in many cases. A diet full of whole foods, lean protein and healthy fats is exactly what your body is craving. Extra calories comprised of refined sugar or carbohydrates don't provide any nutritional value for you, your breastmilk, or your bub. Of course, if you're having a tough day, treat yourself but remember to realign your food and weight loss goals afterwards. 


So, now you know the truth about breastfeeding and weight loss. Yes, breastfeeding burns extra calories, so it is an excellent tool for returning to your goal weight. But it is just one part of the puzzle. If you consume more calories than you're burning, you won't lose weight. But, if you follow the 90/10 rule and eat healthy for 90% of the time with the option for treats 10% of the time, you'll be able to support your milk production and your weight loss goals all at the same time. 



Will you lose weight when you stop breastfeeding?


When you are not breastfeeding, if you ensure the calories you consume are less than the calories you’re burning, you will continue to lose weight. In addition, you may find that you have more inclination for exercise around this time, so incorporating a few walks and a couple of home workouts into your routine will help put you further into a deficit.    



How do In Shape Mummy Health Shakes help you lose weight?


The In Shape Mummy Health Shake can help you reach your goals quicker. It is a calorie-controlled meal replacement. In Shape Mummy is perfect for busy and breastfeeding mums as it is so quick and easy. 


The In Shape Mummy blend is designed to support milk supply, while also balance blood sugar levels, to help reduce cravings and the need for snacking. Every shake is enriched with organic vegan protein, 25 vitamins and minerals and probiotics to support you and your little one 


For best results, replace 1 meal and 1 snack per day with an In Shape Mummy Smoothie, for example breakfast and an afternoon snack.



Can I keep using In Shape Mummy once I stop breastfeeding?


Yes. In Shape Mummy have another range of shakes that are made for Busy Mums. 


The In Shape Mummy Health Shake for Busy Mums contains the same nutrients as the Breastfeeding Shake but it does not contain the galactagogues (milk boosting herbs). 


The Busy Mums Shake is 100% breastfeeding friendly so it is perfect for mums who want to wean their babies as well as mums who are not breastfeeding. It is a great way to continue ensuring you're consuming enough protein, vitamins and minerals.


The Breastfeeding Shake is still completely OK to consume once you have finished breastfeeding, however as it contains milk boosting herbs so it is recommended to take a break for in while during the process of weaning until your milk supply has dried up. 



How much Weight Can I Expect to Lose?


A healthy and safe amount of weight to lose if you're breastfeeding is 2kgs per month, and if you're not breastfeeding 4-6kgs per month.


When you're breastfeeding it is important to lose weight at a slower pace in order to support your milk supply.


Try not to weigh yourself too often as it is important not to get fixated on the scales. We recommend not more than once every 2 weeks. 


Keep in mind muscle weighs more than fat anyway. And your weight can change depending on the time of day, the time of the month and how much have eaten and drunk before you weigh yourself. A better judge is how you feel in your clothes.


Most importantly, think about what you want to gain, not just about what you want to lose. Whether you want to gain more energy, better self-confidence, better health, or whatever it is for you.


Also think about how eating healthy helps your milk supply and helps your baby's development. Thinking about what you want to gain will motivate you to act to achieve your goal.


But also be patient with yourself, and with your body. It took 9 months to gain the weight and to create a beautiful baby, so the weight isn’t going to fall off overnight either. Just stick to balanced eating and your body will naturally achieve its own healthy weight.

"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!”
