Can I Lose Weight While Breastfeeding without affecting my Milk Supply?

Many mums are so terrified of losing their milk supply that they don’t even consider starting their weight loss journey until they’ve stopped breastfeeding. But the truth is you CAN safely and effectively lose weight while breastfeeding, without affecting your supply.

However, to make sure you give yourself enough time to building up a healthy milk supply, we recommend waiting six weeks before embarking on any type of weight loss journey.

Below are the Dos and Don’ts for losing weight while breastfeeding.



  • Focus on nutrients

Focus on eating healthy food to lose weight rather than drastically restricting calories. Your body needs more nutrients when breastfeeding as your baby is 100% depending on you for their nutrition. Reducing calories too low can impact your milk supply and energy levels. Focus on swapping out unhealthy food & drinks for healthy options.


  • Eat a wide variety of foods

Eating a wide variety of healthy foods will give you the broad spectrum of nutrients that your body needs. Eating a balanced diet that is rich in carbohydrates, protein, and healthy fats is vital. When you’re not getting the nutrients you need, your body sends a message that you need to eat more food, when all you really need is more nutrients. This can lead to overeating food your body doesn’t need and weight gain. When you eat a healthy and balanced diet, you will naturally feel satisfied and be less inclined to over-eat. You will also experience less cravings as often cravings are caused by nutrient deficiencies.


  • Pay Attention To Protein

Meeting your protein requirements is essential. Protein helps you to stay fuller for longer, but it also plays a critical role in your recovery and your baby's development. Hitting your protein target will provide you with a sustained source of energy throughout the day and will assist in producing a healthy milk supply and reducing sugar cravings. Good sources of protein include chicken, lean beef, fish, tofu, nuts, eggs, yoghurt, kefir, In Shape Mummy Health Shake.


  • Keep hydrated

Remain hydrated and drink around two litres of waters a day. It's not surprising that we lose a lot of fluid while breastfeeding, as breastmilk is around 90% water. It's important to be proactive, rather than reactive, especially when it comes to breastfeeding. If you do become dehydrated, it can cause a lag in your milk production. Dehydration can also lead to feelings of hunger as your body can mistake thirst for hunger. Water aids weight loss by acting as a natural appetite suppressant, it helps to remove waste from your body and it reduces your liquid calorie intake (when you replace high calorie drinks with water). Tip: fill up a couple of water bottles in the morning and sip throughout the day.


  • Rest

Many mums find their milk supply is affected by their energy levels. We know it can be hard to get the sleep you need, but it’s essential to take time to rest when you can. Even a 5-10 minute cat nap can give you a pick-me-up. A short rest is a healthier option than reaching for a sugary snack or coffee to give you energy.



  • Don't restrict calories

Your body uses the calories you consume to make milk, so dropping calories too quickly could be highly detrimental to your milk supply. If you restrict your calories too dramatically, not only will your milk suffer, but you’ll find yourself feeling completely exhausted.


  • Don't cut out major food groups

Carbohydrates, protein and fat are all essential food groups when breastfeeding. Many mums are tempted to follow a keto diet (a very low carb/high-fat diet) due to the quick weight loss results. However, this is super dangerous for breastfeeding mums as carbs are a vital energy source. What you can do is opt for healthy carb options like sweet potato and banana, while limiting foods like bread and pasta.


  • Don't eat junk food

Not only does junk food work against weight loss, but it also drains your energy. Your body is like a high-performance car that needs the right fuel to run. It cannot operate properly when filled with junk. 


  • Don't skip meals

Skipping meals can lead to feeling more hungry (or "hangry"!) and reaching for the wrong foods later in the day. Aim for breakfast, lunch, and dinner plus morning and afternoon snacks. Eating smaller meals more often is a good strategy.


A Solution to Help...

There’s no doubt that being a new mum can feel overwhelming. The effects of sleep deprivation, fluctuating hormones and pregnancy-related anxiety can feel intense. Preparing healthy food all the time can be a challenge. The In Shape Mummy Health Shake is the helping hand you need to lose weight without affecting milk supply.  


The In Shape Mummy Health Shake provides breastfeeding mums with a good serve of protein, 25 vitamins and minerals and contains milk supporting ingredients including fenugreek and milk thistle.


Most Mums want to get back to their pre-bub weight as soon as they can, and with the tips above and In Shape Mummy Health Shake, they can do that and still enjoy a healthy milk supply.


And remember Mumma, it took a whole nine months to gain the weight, so you need to allow a little time for it drop off. Jumping on the scales everyday isn’t going to be good for your mental health and won’t help you to lose weight any quicker. Instead, aim to weigh yourself once every two weeks, on the same day, first thing in the morning. Most importantly, enjoy this special time. It won’t be long until you’re sleeping a full 8 hours dreaming of those nights it was just you and bub under the milky way.

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!”

"I have lost over 30kg with In Shape Mummy Health Shakes, exercise and a complete diet change. ⁠⁠ I started at size 22 and am a loose size 12 at the moment… and nearly a 10! ⁠I feel so much better! With my injuries in my spine, pelvis and knee my weight loss has been the best thing for my pain. ⁠
7-8 months ago I couldn’t have even imagined I could drop this much weight! The change in my life has been insane! ⁠ My advice to other mums is “stick with it and don’t give up!” ⁠ Thanks so very much for your In Shape Mummy Health Shakes. They are the best thing for mums on the go and while breastfeeding as well. Words can not express how grateful I am with my weight loss. I couldn’t of started this without your shakes. My life is forever changed." ⁠
