Which Milk Is Best For Weight Loss?

"I just want milk that tastes like real milk – but is also low in calories, high in protein, has adequate fat and no added sugar."

When did milk become so confusing?

Not too long ago, our milk choices were either full fat or skim. But now, the supermarket fridge is a little busier. Coconut, almond, soy, rice, hemp, oat and cashew are just some milk alternatives gaining popularity.

Choosing the right milk is no easy task, so let's look at Australia's top milk choices and unpack the pros and cons of each.

Unsweetened Almond Milk

Almond milk is the most popular milk alternative today - most likely because it has the lowest calories. One cup of almond milk has just 44 calories, which is drastically lower than regular milk which has 155 calories per cup. These days, it would be rare to find a café that didn't stock almond milk, so it's a safe bet. The downfall? It has one of the lowest protein contents of any milk alternative. So if you are drinking almond milk, ensure you are getting your protein from other sources.

Unsweetened Oat Milk

Oat milk is fast gaining popularity in the world of milk. This vegan alternative is made by blending water and oats and then straining out the liquid. It surprisingly tastes pretty close to cow's milk with a pleasantly creamy texture. Oat milk has around the same number of calories than cow's milk. However, it does come with more carbs and less protein than cow's milk. While the carborhydrates found in oats are complex carbs that are essential to your health, those on a low carb diet may want to keep a watch on their overall daily carb intake. 

Oat milk is a good alternative for those with intolerances to dairy and soy. Compared to almond milk it does have 3 times more calories than almond milk and signifcantly higher carbs. So, when it comes to weight loss, almond milk may be a better choice.

Soy Milk

Soy milk is the only milk that comes close to matching the protein content of regular milk. It's also low in saturated fat, which is beneficial when you're aiming to lose weight. However, soy is a prevalent allergen. Soy contains estrogen-like compounds called isoflavones, with some research linking these compounds with impaired female fertility and compromised thyroid function. In short, with so many milk alternatives out there, it makes sense to steer clear of soy.

Cow's Milk

Regular cow's milk ranks number one in terms of highest calories and fat. If you're having a couple of coffees a day, plus adding milk to your smoothie, you might find your daily calories are adding up quite quickly. The benefit? The higher fat content will keep you satiated and fuller for longer. So, you might find you don't need as many snacks throughout the day.

Low Fat Cow's Milk

For those who don't want to give up real milk but want to shed some extra kilos, low fat cow's milk might be your best bet. With 53 fewer calories and 5.8g less fat than regular cow's milk, transitioning to low fat might be the key to shifting those stubborn kilos.

Just keep in mind that dairy and lactose are common allergens. Lactose intolerance, in particular, is common in mums and bubs and often goes undiagnosed. If you’re noticing you’re bloated, gassy or nauseous; this could be due to lactose.

If your bub is crying for extended periods or is extremely unsettled, it could indicate that they’re intolerant. If you suspect your baby has a diary or lactose intolerance, it’s essential to seek advice from your doctor/pediatrician.

So, which milk is best for weight loss?

If you're up for transitioning to a milk alternative, almond milk has the lowest calories, by a long shot. If you're not quite ready to break up with cow's milk but have difficulty shifting weight, opt for low fat or reduce the amount of full-fat milk you're consuming.

If you’re transitioning from cow’s milk to a milk alternative, it’s vital to ensure you’re meeting your calcium requirements through other food sources. Sardines and dark leafy green vegetables and two great non-dairy options. You can also find non dairy milks fortified with calcium.

Finally, remember to always read the ingredients list when shopping for a new milk alternative; some brands have added sugar to enable a longer shelf life. Opt for alternatives with the shortest ingredient list and choose an unsweetened version to make sure your milk doesn't get in the way of your weight loss goals.

"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!”
