Meal shake vs protein shake

They might look the same, but by law a meal replacement has to do a lot more than a protein shake.

Why ours are the shakes people stick with.

The taste

Tastes like a real milkshake. Honestly.

We've spent years getting the recipe right, so every shake is smooth and creamy, with no gritty texture and no chalky aftertaste. The kind of shake you look forward to, not one you force down.

  1. 01Smooth, not grittyMixes with no lumps in a few seconds of shaking.
  2. 02No chalky aftertasteNaturally sourced sugars, about a teaspoon a shake.
  3. 03Blend it thickAdd ice and blend for a proper thick shake.

The range

12 flavours. No two days the same.

Classics, fruity and full-on dessert flavours, all with the same nutrition. Mix as many as you like in one box.


The options

A shake for however you eat.

Every product page shows exactly what each flavour suits. Filter by any of these when you build your box.

Milk based

Mix with skimmed or unsweetened soya milk for the creamiest shake, 200–224 kcal.

Water based

Just add cold water. Lighter, and ready wherever there’s a tap.

Gluten free

Most of the range, including Chocolate, Vanilla and Strawberry.

Vegetarian

Our classic whey-based shakes are suitable for vegetarians.

Vegan

Tropical, Cherry Bakewell and Chocolate Hazelnut. Dairy free, same protein.


The science

Made to meal replacement standards.

Not a protein shake. Each one is built to replace a whole meal, with the calories and nutrients fixed so there's no guesswork.

Milk or water?
Both taste great.

Milk makes a slightly thicker shake, water a lighter one. Either way, the flavour is just as good.

Made to mix with milk

Most of our shakes are designed for 250ml skimmed or unsweetened soya milk, which adds protein, calcium and creaminess.

Want it lighter? Mix any of these with water instead for around 125 kcal. Mixed with water it's a lighter option, not a full meal replacement. For a complete meal, mix with milk.

Made to mix with water

The most convenient option. Everything’s already in the sachet, so just add cold water and shake. No milk, no fridge, ready wherever you are.

Our diet plans

Plans to suit all shapes,
sizes & lifestyles.

Compare all plans →
Can I mix them with water instead of milk?
Yes. Our milk-based shakes are best with skimmed or unsweetened soya milk (200–224 kcal). Mixed with water they come to roughly 125–150 kcal. Water-based flavours are made to be mixed with water.
How many shakes can I have a day?
For weight loss we recommend replacing two main meals a day. You can have up to four a day on the Total Plan, an 800 kcal day made entirely of meal replacements.
Is a meal replacement shake the same as a protein shake?
No. A protein shake tops up your protein. Ours are calorie-controlled with 20+ vitamins and minerals, protein and fibre, so they’re designed to replace the meal itself.
Do they keep you full?
The protein and fibre in each shake are designed to help you feel full until your next meal.
Do they contain artificial sweeteners?
It varies by flavour and each product page states which. We only use naturally sourced sugars, around a teaspoon per shake.
Can I have them alongside a weight loss injection?
Yes. They pack a lot of protein and nutrition into a small serving, which can suit a reduced appetite. Your prescriber’s guidance always comes first.
