Do meal replacement shakes work for weight loss? They can help, when they keep you full, fit into your morning and sit comfortably. Comfort is where many shakes fall down.

We’ve been reading the reviews on Lean Up Shake, our Australian slow-digesting protein and collagen meal shake with BIMUNO® prebiotics, and the same themes keep coming up: staying full for hours, less bloating, quieter cravings and a taste people actually look forward to. Here are the seven reasons customers keep telling us they love it.

In Short

Replacing a meal with a high-protein shake can make it easier to manage your calorie intake without feeling deprived.
Customers say Lean Up Shake keeps them full for hours and has been gentler on their stomach than other protein shakes.
Some customers report noticing weight loss, and results build over time alongside balanced eating and movement.

What real customers say about a meal replacement shake that keeps them full and comfortable through the morning.

What’s Inside (and Why It Matters)

A shake only works if you can stick with it, so the Lean Up Shake formula is built around these key ingredients:

Australian slow-digesting protein. It digests gradually, which is why customers describe lasting fullness instead of hunger returning within the hour.
Collagen. A second protein source that rounds out the formula alongside the main protein.
BIMUNO® prebiotics. A prebiotic GOS (galacto-oligosaccharides). According to the ingredient’s manufacturer, it is backed by more than 130 scientific publications [1].

Each serve also delivers 30 g of protein and 10 g of collagen, plus digestive enzymes and a BC99® probiotic, and it’s free from sugar, gluten, soy and artificial flavours.

It comes in Rich Chocolate and French Vanilla Cream, and customers also mention the added vitamins.

1. It Keeps You Full for Hours

This is the number one thing customers tell us. Slow-digesting protein releases gradually, so the “I’m starving again” feeling doesn’t arrive at 10am.

“I usually enjoy a mid morning snack but these keep me full for hours. So good.” — Kieran E.

Several other customers describe the same thing, from feeling satisfied after a meal swap to staying full for hours. For anyone trying to lose weight, a shake that keeps you satisfied is a shake you’re more likely to stick with.

2. The Protein Does the Heavy Lifting

Research reviews report that higher-protein meals can increase feelings of fullness [2]. Customers connect the two directly.

“I have lost weight mainly because this keeps me full with all that protein!” — Elizabeth R.

Elizabeth blends hers with almond milk, or stirs it into Greek yoghurt for a big morning protein hit.

3. Customers Say It’s Gentle on the Stomach

If you’ve ever finished a protein shake and felt tight, gassy and uncomfortable, you’re not alone. Discomfort is a common reason people give up on shakes, which is why the formula pairs slow-digesting protein with BIMUNO® prebiotics. Several customers with sensitive stomachs have told us about their experience.

“Whenever I’ve tried protein shakes in the past, I’ve experienced nothing but dreadful bloating. This is different, no bloating, full for hours.” — Natalie H.

“Delicious and tasty. Keeps me feeling satisfied without the bloat.” — Miranda B.

JB said it “definitely flattened the bloat” within days. Everyone’s gut is different, but feeling comfortable after your shake makes it much easier to keep going.

4. Cravings Get Quieter

Weight loss isn’t only about willpower. It’s about not being ambushed by cravings every afternoon. Customers say the shake quietens that noise.

“It tastes so good and gives me a great protein boost. It keeps craving away and makes staying on track effortless!” — Mercy A.

Natalie noticed the same thing: alongside feeling full for hours, her food cravings started fading.

5. It Tastes Like a Treat You’ll Actually Look Forward To

The best shake is the one you’ll still be drinking in week six. Taste comes up in nearly every review.

“I love the chocolate taste; genuine chocolate flavour and not too sweet.” — Elizabeth R.

“I loved the taste of the chocolate shake. I actually looked forward to it every morning.” — JB

Natalie called both flavours “delicious, not grainy or too artificial tasting”.

6. It Fits Into Real, Busy Mornings

The easiest habit to keep is the one that takes a minute.

“Tastes good and easy to use. Great for commutes and work travel too.” — Gina W.

A few ways customers make it their own:

Shaken with skim or almond milk
Mixed into Greek yoghurt for a thicker, spoonable breakfast
Whisked with a handheld milk frother for an extra smooth shake

7. Customers Keep Reordering

The real test of any shake is whether you’re still using it a month later. Some customers, like Elizabeth, have stocked up on multiple jars.

“Will be ordering again. Highly recommend.” — Natalie H.

“Love this product and as per the other reviews, it tastes real good and plenty in the tin which was a nice surprise!” — Lorelle K.

What the Research Says and What to Look For

So do meal replacements work for weight loss? A 2019 systematic review of 23 randomised controlled trials, covering 7,884 adults with overweight or obesity, found that programmes including meal replacements led to greater weight loss at one year than comparison programmes [3]. That’s research on meal replacements in general, not Lean Up Shake specifically, and results build over time, so a shake works best as a consistent daily habit alongside balanced eating and regular movement.

If you’re comparing shakes, whether you’re after the best option in Australia or just a better fit for you, use the same checklist on every one: protein type and amount per serve, gut support, collagen, vitamins, taste and texture, sweeteners, any ingredients you react to, and value. Lean Up Shake combines Australian slow-digesting protein with collagen and BIMUNO® prebiotics.
