What is the best meal replacement shake for weight loss?

When it comes to weight loss shakes, not all products are created equal. If you’re considering this effective weight loss method, keep reading to see what to look for in the best meal replacement shake for weight loss.

What to look for in the best meal replacement shakes

In Australia, meal replacement products have to meet certain criteria to be classified as a formulated meal replacement. This is to make sure you still get a baseline of nutrition when you drink a shake instead of eating a meal. So the first thing to look for in the best shakes are the words “formulated meal replacement” on the label. 

For an effective weight loss shake, you also want to make sure it’s high in protein, fibre and micronutrients.


We know that a higher protein diet is key to sustainable weight loss and maintenance (trust us – we’ve done the research!)

Eating a balanced amount of protein throughout the day will keep you feeling full and reduce food cravings. Plus, when it comes to weight loss, getting enough protein helps your body retain muscle mass while losing fat.

CSIRO Total Wellbeing Diet Fast Start shakes are packed with protein, with 25 g per shake when prepared. That’s on par with one steak, 3.5 eggs or 1.5 tins of tuna!


Fibre is essential for good gut health, and good gut health is key to overall health. Replacing wholefoods in your diet with a shake means missing out on important sources of fibre (think fruit, veggies and wholegrains). That’s why the best meal replacement shakes will be high in fibre.

Fibre, along with protein, is also responsible for keeping you feeling full, which reduces food cravings.

Fast Start shakes feature a whopping 7 g of fibre per serve. Taken along with unlimited veggies for snacks and a Total Wellbeing Diet dinner, Fast Start makes it easy to reach your recommended daily intake of fibre.

Nutritionally complete

Formulated meal replacements need to meet a minimum amount of added vitamins and minerals. Without these, you miss out on the vital micronutrients your body needs for good health.

The best shakes for weight loss, like our Fast Start shakes, will be fortified with essential micronutrients like B vitamins, vitamins C, A, K, D and E, as well as iron, magnesium, calcium and more.

How much weight can I lose with meal replacement shakes?

Meal replacement shakes can help you lose a significant amount of weight in a short timeframe. Our research shows that on average, members lost 4.1 kg in the first three weeks of the Fast Start program (taking two meal replacement shakes per day). 80 percent of members also reported they felt better at controlling their cravings by the end of week three.

While drinking meal replacement shakes can deliver fast results, it won’t deliver long term results. To maintain weight loss, research suggests the best course of action is to transition from the shakes into a healthy wholefood diet.

Is protein powder good for weight loss?

Protein powder can be a useful addition to your diet in certain situations, such as when you’re hungry but have no wholefood options. But unlike meal replacement shakes, protein powders are not nutritionally complete (meaning they’re not fortified with fibre, vitamins or minerals), so they can’t be taken in place of a meal.

Protein shakes can have their place in a healthy weight loss diet, but wholefoods should always be your first stop when it comes to nutrition. If you do choose to drink a protein shake, try to pick one that has no added sugars, flavours or additives.
