Buying diet shakes in Australia (our favs and tips from a health expert)

Diet shakes Australia

Many people swear by diet shakes as part of their diet regime. They can eliminate the fuss of making a meal whilst providing the vitamins and minerals you need to get you through the day.

Whether you’re looking for diet shakes for a quick weight loss fix, or you’re looking for a long-term solution to keep you trim, there is heaps of choice available. Some would say too much!

What I like most about diet shakes is that they take away the meal prep. The less I am around food, the less I want it. Even preparing a low calorie meal makes me hungry. With the shakes, you can just whizz them and get outta the kitchen!

I’ve broken it down and found the best diet shakes on the market right now. Plus, I’ve included all the facts you need to compare and pick the right diet shake for you.

Exciting new addition to article: Since first writing this article a few years ago, I’ve discovered new diet shakes so I’ve left in my favourites and swapped some out for my top newcomers to the shake market. And, because what we put in our bodies is so important, I’ve enlisted the help of Catherine Gervacio from the E-Health Project, a highly regarded US-based online provider of Health News and Medical Research updates, to explain the following:

  • What to consider before using shakes to lose weight
  • How to make diet shakes work for you
  • How to choose the right diet shake for your health goals

Other than being a registered dietitian, and a certified exercise nutrition coach, Catherine is experienced in helping women (mostly) achieve their health and wellness goals. With years of practice, including meal planning, nutrition consultation, and accountability coaching, she’s the perfect person to provide the facts we need about these shakes.

After all, I can tell you which diet shakes in Australia I love but professional advice is super important when it comes to our personal health goals … especially when the aim is to create a healthier version of ourselves.

What to consider before using shakes to lose weight

Over to Catherine for this one. She says:

The nutritional content of the diet shakes should be considered most importantly! It’s best to look for options that provide a balance of macronutrients (carbohydrates, protein, and fats) with essential vitamins and minerals. Also, consider what you truly need. Are you wanting to lose weight? Tone muscles? Manage a health condition? These questions will help you determine what particular diet shakes you need. There are high-protein, sugar-free, or other varieties that can go well with your health and fitness goals.

Most importantly, I have to say that relying solely on diet shakes isn’t ideal. You want to include a variety of whole foods in to ensure improvement or maintenance of health.

How to make diet shakes work for you

Our in-article dietician and nutrition coach, Catherine Gervacio says:

Ideally, you want to make your diet shake. This is to ensure that you’re adding ingredients that you need and align to your own calorie and macronutrient needs. A whey protein or a pea protein can be used as a protein source, especially when high-protein is being aimed for. Then, add a liquid base using unsweetened almond milk, soy milk, or non-fat dairy milk. Fruits and vegetables should be added for nutrients and fiber, then add seeds or nuts for healthy fats. To make it flavorful, add a dash of vanilla or cinnamon!

On the other hand, if preparing your shake is impossible, make it work for you by choosing a quality shake that aligns with your goals, as I mentioned above. Strategise your intake by knowing your caloric requirement and tracking it. This will help you figure out what other foods you can combine with your shake to meet your daily nutrition goals.

You also want to stay active by doing regular exercises. This helps you burn calories and improve your metabolism to support health and well-being.

How to choose the right diet shakes in Australia for your health goals

Catherine clarifies this for us here:

Other than the ones I mentioned above, check for allergens. If you have food allergies or sensitivities, check out the ingredients list and see if the shake is safe for you to consume. Also, check if the taste and texture align with your preferences. Maintaining a healthy diet necessitates sustainability. Therefore, it’s best to choose a product that you can enjoy and be able to stick with it in the long run.

Most importantly, seek the advice of a healthcare professional especially if you are managing a health condition. They can give you advice as to which particular product or brand you should focus on according to what your body needs.

Summary: Buying diet shakes in Australia

Diet shakes can offer a convenient solution if you want to manage your weight and improve your health.

Personally, I find their simplicity appealing, as they eliminate the need for time-consuming meal preparation and reduce temptation around food. With a wide variety of options available, from low-calorie choices like The Healthy Mummy to specialised programs such as Optifast, there’s something to suit every preference and goal on the Australian shake market.

Expert insights from Catherine Gervacio emphasise the importance of considering nutritional content, aligning with personal health goals, and seeking professional advice before incorporating diet shakes into your routine.

I have learned that while diet shakes can be a helpful tool, they are most effective when used alongside a balanced diet and regular exercise.

Happy shaking ladies!
