Protein Works Diet Meal 360 GOLD Review: Speculoos Biscuit Heaven

I bought Protein Works Diet Meal 360 GOLD in Speculoos Biscuit Heaven and drank it as a stand-in breakfast and lunch. Here is what the flavour, texture, mixability and £1.33-a-meal cost are actually like, and one thing that would take it to the next level!

Quick answer

Protein Works Diet Meal 360 GOLD costs about £1.33 per 65g meal at £39.99 for the 2kg Speculoos Biscuit Heaven bag, checked 19 September 2026, or about £1.17 a meal with WheyWise's permanent WW12 code at Protein Works. It is thick, filling and mixes clean in an ordinary shaker with 350ml of water, one important thing to consider when deciding the quantity is that one meal requires roughly two scoops.

Protein Works Diet Meal 360 GOLD in Speculoos Biscuit Heaven is a nutritionally complete meal replacement that costs £39.99 for the 2kg bag at Protein Works, checked 19 September 2026. That bag holds 30 meals of 65g, so one meal costs about £1.33.

I bought this bag and drank it as a stand-in breakfast and lunch, and scored it 8.5 out of 10. This review covers what Speculoos Biscuit Heaven actually tastes like, how thick it is, whether it mixes in a normal shaker, how full it keeps you, how it digests and what it costs per meal.

Is Protein Works Diet Meal 360 GOLD worth buying?

Protein Works Diet Meal 360 GOLD is worth buying if you like thick, dessert-style shakes and want a fast breakfast or lunch, however, if you are looking for a completely smooth drink, you may want to look at some other options they have to offer! Speculoos Biscuit Heaven is rich, filling and genuinely enjoyable, with a caramelised biscuit flavour that does not hang around as an artificial aftertaste!

It mixes well in an ordinary shaker bottle, so it travels. Only thing that would be great is if the serving size for a meal was just one scoop. The serving size: a complete meal is 65g of powder, which is roughly two scoops per meal.

My rating: 8.5 out of 10. Protein Works Diet Meal 360 GOLD in Speculoos Biscuit Heaven wins on flavour, mixability and cost per meal, and loses points only on the two-scoop serving and the fine biscuit particles left in the finished drink which is pretty minor if you ask me!

Tested by hand: 2kg Speculoos Biscuit Heaven

Pros

  • Caramelised biscuit and vanilla flavour that fades quickly instead of leaving an artificial aftertaste
  • Mixes clean in a standard shaker with a ball whisk and 350ml of water, no blender needed
  • Thick enough to genuinely replace a meal rather than just top one up
  • About £1.33 per 65g meal at £39.99 for the 2kg bag, checked 19 September 2026
  • WheyWise's WW12 code takes 12% off at Protein Works, bringing the 2kg bag to about £35.19, or roughly £1.17 a meal

Cons

  • One complete meal is 65g, which is roughly two scoops
  • Fine biscuit particles leave the finished drink slightly grainy
  • The lowest advertised per-meal price needs a subscription, not a one-off order

What does Speculoos Biscuit Heaven taste like?

Speculoos Biscuit Heaven tastes of caramel, biscuit and vanilla, and the flavour clears from your mouth within seconds of swallowing rather than lingering. That fast clearing is the single best thing about it, because plenty of meal replacements leave a strong artificial edge behind for minutes.

When opening the bag, you are met with a sweet biscuit aroma that matches the drink, which is a big plus as I’m sure people might be able to relate with opening a bag which smells nothing what it says on the label.

I’d say the flavour is the biggest reason to pick this particular variety of Protein Works Diet Meal 360 GOLD over the plainer options in the range and other options available on the market at that! Another great thing here is that you do not get that artificial taste that you can with some other shakes! It tastes just like a dessert, so you don’t actually feel like you are even missing out on a normal meal and feels like a treat rather than punishing yourself for dieting.

How thick is Protein Works Diet Meal 360 GOLD?

Protein Works Diet Meal 360 GOLD is a thick consistency, it is like a milkshake, so if you’re looking for that consistency you would like this but if you prefer a lighter protein drink without bits, you might find this a bit on the heavier side but each to their own as I personally liked this consistency!

Speculoos Biscuit Heaven texture includes small biscuit-like particles (reminded me of a Biscoff milkshake). They leave the drink slightly grainy as you get through it but again, I feel like this is something you might expect with a diet shake! Just make sure you don’t mistake this particular product for unmixed powder: it appears to be part of the flavour itself, so a plainer flavour in the same range would not have this same consistency.

If textured drinks put you off, you can always just add more water rather than less powder, cutting the powder also cuts the nutrition the serving is built to deliver.

Does Protein Works Diet Meal 360 GOLD keep you full?

One 65g serving of Protein Works Diet Meal 360 GOLD kept me full through a meal I would otherwise have skipped, without sending me looking for a snack shortly afterwards. That was the real test for me, not the label.

I made it on a day when I did not want to cook or even build a sandwich. It killed the craving and then kept me feeling full and I think the thickness is doing most of that work, because it sits far more like food than a normal protein shake does.

Based on that, it earns its place on busy days, when the alternative is missing a meal outright or grabbing something worse. It takes a minute to prepare and still behaves like an actual meal.

Does Protein Works Diet Meal 360 GOLD mix in a shaker?

Protein Works Diet Meal 360 GOLD mixes cleanly in a standard shaker bottle with a ball whisk, 350ml of water and a few cubes of ice, with no blender needed. For a shake this thick, that surprised me.

I have not hit large clumps or dry pockets of powder in a finished drink. The powder can look a little clumped inside the bag, but that has never survived contact with the shaker.

The fine particles left in the finished drink come from the Speculoos flavour rather than from poor mixing, so a different flavour in the range would likely finish smoother. Not needing a blender is what makes this practical to take to work.

How big is a serving of Protein Works Diet Meal 360 GOLD?

A complete serving of Protein Works Diet Meal 360 GOLD is 65g of powder, roughly two scoops, mixed with 350ml of water. That is my biggest criticism of the product.

If Protein Works shipped a larger scoop that measures the full 65g in one go, or found a way to deliver the same complete nutrition in less powder this could take this to the next level.

Is Protein Works Diet Meal 360 GOLD easy to digest?

Another big plus was that Protein Works Diet Meal 360 GOLD digested comfortably for me, with no stomach discomfort, no headaches and nothing sitting heavily afterwards.

Digestion is personal - your experience may be different to mine, but for what it is worth, a shake this thick is exactly where I would expect some discomfort if there were any, and there was not!

How much does Protein Works Diet Meal 360 GOLD cost per meal?

Protein Works Diet Meal 360 GOLD costs £39.99 for the 2kg Speculoos Biscuit Heaven bag at Protein Works, checked 19 September 2026, which is 30 meals of 65g at about £1.33 each.

Protein Works advertises a lower price on subscription, around £1.27 a meal when I bought mine, and its one-off list price sits nearer £1.48 a meal before any sitewide sale. Which of those you actually pay comes down to whether a promotion is running when you land on the page, which is exactly why WheyWise shows the scraped retailer price on the Diet Meal 360 GOLD product page rather than an advertised one.

There is one discount I can be certain about, and that’s because it’s ours. WheyWise has a permanent 12% code at Protein Works, WW12, open to every customer rather than new ones only. Applied to the £39.99 bag that is about £35.19, which works out at roughly £1.17 a meal. The card above carries the code and its terms.

Weighing this up against buying breakfast or lunch out, £1.33 is cheap! I treat this as a replacement for any meals I plan to skip and as an easy alternative to add to my diet plan! The great thing is that they are easy to prepare and take with you on the go and they are also fortified with vitamins which ensures that you are getting some health benefits from the shake!

Inside the Diet Meal 360 range, Diet Meal 360 BLACK costs £30.99 for its 2kg bag, about £1.03 a meal, which makes Diet Meal 360 GOLD roughly 30p a meal more expensive, checked 19 September 2026. Diet Meal 360 PLATINUM, the tier above, costs £43.99 for its 2kg Speculoos Biscuit Heaven bag, £4 more than the GOLD bag on the same date.

All in all, I will be keeping this on my top list of diet shakes and will be trying more of Protein Works range!

If you want to set those three against the rest of the market, the meal replacement shake guide ranks the UK field, and the protein comparison tool will put any two of them head to head on price and nutrition.

The step up from GOLD

Pros

  • Protein Works positions PLATINUM as its most complete meal replacement tier, above Diet Meal 360 GOLD
  • Sold in Speculoos Biscuit Heaven too, so the flavour I rated 8.5 out of 10 carries over
  • £43.99 for the 2kg bag, only £4 more than the Diet Meal 360 GOLD bag, checked 19 September 2026

Cons

  • Costs more per bag than both Diet Meal 360 GOLD and Diet Meal 360 BLACK
  • I have not tried the PLATINUM version myself, so I cannot vouch for its texture the way I can for GOLD

What is good and what is not about Diet Meal 360 GOLD?

What works: the caramelised biscuit and vanilla flavour, the smell when you open the bag, the clean mix in an ordinary shaker with no blender, the thickness that makes it feel like food, the aftertaste that does not linger, the comfortable digestion, and about £1.33 a meal, or roughly £1.17 with our WW12 code, for something you can make in a minute at your desk.

What does not: the 65g serving that needs roughly two scoops, the thickness may not be to everyone’s taste as the fine biscuit particles keep it from being smooth. The space two scoops of powder takes up in a bag, and the fact that the cheapest advertised per-meal price is a subscription price rather than what a one-off order costs.

Final verdict on Protein Works Diet Meal 360 GOLD

Protein Works Diet Meal 360 GOLD in Speculoos Biscuit Heaven scores 8.5 out of 10 from me: a very good meal replacement for anyone who likes thick, dessert-inspired shakes.

Its strengths are flavour, smell, cost per meal and reliable mixing. The biscuit pieces give it substance and keep you feeling satiated inbetween meals! It would be great if it was only a one scoop serving instead of two but that would be my only suggestion for improvement!

If you like rich, thick, tasty shakes and want a cheap meal replacement for busy days, work lunches and travel – this is definitely for you!

Frequently asked questions

Is Protein Works Diet Meal 360 GOLD a full meal replacement?

Yes. Protein Works Diet Meal 360 GOLD is sold as a nutritionally complete meal replacement, and one complete serving is 65g of powder mixed with 350ml of water. I found one serving filling enough to stand in for a breakfast or lunch rather than leaving me hunting for a snack an hour later.

How many scoops is a serving of Diet Meal 360 GOLD?

A complete serving of Protein Works Diet Meal 360 GOLD is 65g, which is roughly two scoops. This is my main complaint about the product: one larger scoop measuring the full serving would make it much easier to carry a measured meal to work.

Does Speculoos Biscuit Heaven mix without a blender?

Yes. I mixed Protein Works Diet Meal 360 GOLD in Speculoos Biscuit Heaven in a standard shaker bottle with a ball whisk, 350ml of water and ice, with no large clumps or dry pockets. The fine biscuit particles left in the drink come from the flavour itself, not from unmixed powder.

Protein Works Diet Meal 360 GOLD costs £39.99 for the 2kg Speculoos Biscuit Heaven bag, which is 30 meals of 65g at about £1.33 each, checked 19 September 2026. WheyWise's permanent WW12 code takes 12% off at Protein Works, bringing that to about £35.19, or roughly £1.17 a meal.
