How Many Calories Do You Need to Lose Weight?

How Many Calories Do You Need to Lose Weight & Support Milk Supply?

Losing weight as a busy mum can feel overwhelming—you're juggling kids, work, and life, and your body has unique needs. Extreme dieting isn’t the answer. Instead of deprivation or starvation, the key to lasting success is nourishing your body with the right foods while following a balanced, sustainable approach.


By focusing on nutrient-dense meals and a realistic calorie intake, you can lose weight while keeping your energy levels, metabolism, and overall well-being in check.



So how many calories do you need to eat to lose weight in a sustainable way?

Your Weight is a Result of an Energy Equation


At its core, weight loss comes down to an energy equation:
🔥 If you burn more calories than you consume, you lose weight.
⚖️ If you take in more than you burn, you gain weight.


But here’s the catch—eating too few calories can actually slow down your progress! When your body doesn’t get enough energy, it goes into “starvation mode,” slowing metabolism and holding onto fat.


This is why extreme diets don’t work. A 90kg mum has different calorie needs than a 65kg mum, yet many diets prescribe the same low-calorie number like 1,200 calories for everyone. This approach is flawed because:


🚫 It ignores individual needs
🚫 It leads to fatigue and cravings
🚫 It isn’t sustainable


Plus, weight loss isn’t just about calories—it’s also about what you eat. You could lose weight by eating only carrots, but you'd feel exhausted and deprived as you'd be missing out on key nutrients like protein that come from eating a healthy and balanced diet. No one can live like that forever. This is why 95% of diets fail—the weight comes right back once you stop.


Instead of restriction, think of food as fuel. The right nutrients keep you energised, support your metabolism, and help you feel your best.


If you're breastfeeding, it’s even more important to eat nutrient-rich foods—your baby depends on you for 100% of its nutrition!


The Key to Healthy Weight Loss


✔️ Eat nutrient-dense, whole foods
✔️ Maintain a realistic calorie balance
✔️ Stay active at a moderate level


💡 The  In Shape Mummy Health Shake  is a quick and easy way to help you get the nutritients you need while losing weight.



How Many Calories Should I Eat to Lose Weight?


We don’t recommend obsessively counting calories—it’s too much work for busy mums! But having a rough guideline can be helpful.


🎯 Not sure how much you should be eating?

How Much Weight Can I Expect to Lose?


For non-breastfeeding women, a healthy weight loss rate is 4-6kg per month with a balanced diet and regular physical activity.


But remember—weight loss isn’t just about numbers on the scale! Other signs of progress include:

✔️ Clothes fitting better
✔️ Increased energy levels
✔️ Feeling stronger and more confident

"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." ⁠
