Why Slow & Steady Wins the Race

Although we want results now, if you are breastfeeding, you need to be patient to protect your milk supply. When you're breastfeeding, a healthy weight loss goal is 2 kilograms per month. If you are not breastfeeding you can aim for 4-6 kilograms per month. Any program that promises more weight loss than that is probably a fad diet of some kind and not suitable for breastfeeding.

Breastfeeding In Shape Mummy customer, Carly, lost 35 kgs in 18 months (losing an average of 2 kgs per month). Siobhan lost 11 kgs in 5 months). 

Research shows that people who lose weight more rapidly are more likely to gain it back. This is because that the methods used to lose weight rapidly are not sustainable. Sure eating only carrots for weeks would make you lose weight rapidly. But you would not have any energy and your milk supply would be impacted if you're breastfeeding. And, as soon as you returned to eating normally again the weight would also return. On top of that your metabolism could be slowed down long term, making weight management even more difficult.

Remember it is not just about the number on the scale!

Following a weight loss program is not just about the number on the scale, but improving health matters too. Especially if you need to maintain your energy to take care of a family. And, if you are breastfeeding, you need to be healthy to maintain your milk supply.

A recent study, published in the American Journal of Clinical Nutrition, analysed the micro-nutrient composition of four popular diets (Atkins, Zone, LEARN, and Ornish) to determine their nutritional adequacy. Overweight participants were required to follow one of the assigned diets for 8 weeks. No vitamin or mineral supplement as required by the study.

After eight weeks of being on the diets, over 25% of women had nutrient levels lower than the daily requirement for thiamine, folic acid, vitamins C, A, and E, iron, and magnesium. Eliminating entire food groups, which many of these diets do, may result in vitamin and mineral deficiencies, which are never good for overall health or maintaining energy.

So what do you do if you want to lose weight?

You don't need to go on a diet to lose weight. Instead, aim to eat and drink healthy for 90% of the time and get regular exercise, e.g. a daily walk.

Aim to get balanced nutrition that includes lean protein, whole grains, lots of fruits and vegetables, and healthy fats. Each food group provides a specific nutrient your body needs to function properly, so make sure each meal is well-balanced.

Eating well balanced meals is not always possible for busy mums, which is why the In Shape Mummy Health Shake can be a big help as it contains all the nutrients of a healthy and balanced meal and is quick and easy to prepare. It is scientifically formulated to help Breastfeeding and Busy Mums get the vitamins, minerals, dietary fibre and easy to digest protein they need to lose weight, along side a balanced diet.

Even though it may be tempting to try to speed up your weight loss, do not eat less than 1200 calories per day. If you eat less than 1200 calories per day, it is too difficult to fit in all the nutrients your body needs (plus if you are breastfeeding, you may affect the quantity of your milk supply and the nutrition you are providing to your bub).

Remember, it took 9 months to gain the weight and create a beautiful baby, so the weight isn’t going to fall off overnight either. Just stick to a balanced eating program and your body will naturally achieve its own healthy weight.

"I'm loving it so far.. I'm already down from in weight and I feel great :)  Not exaggerating when I say this is the best purchase I ever made .. can't wait to get to my first mini goal of 65kgs then set my new goal of 60kgs :) .. so far it's been life changing, thank you so much!! 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." ⁠
