People making shakes at home
An unsweetened drink lets you choose the other ingredients yourself. Alpro UK lists 0g carbohydrate per 100ml for its Roasted Almond No Sugars Drink, but anything blended into it needs its own label check.
Who is choosing?
The useful starting point depends on whether you want to prepare a shake, open a finished drink or follow a prescribed diet.
Buyers who want a ready-to-drink option
A finished drink needs no recipe planning, but its front-of-pack sugar wording is not the same as its total carbohydrate content. Tesco Groceries lists 14g carbohydrate per stated 200ml serving for the no-added-sugar Mars Chocolate Flavoured Milk Drink.
People following a prescribed ketogenic diet
Use the individual plan from your specialist team rather than a general keto-friendly description. NHS Specialist Pharmacy Service says carbohydrate allowances vary; Cambridge University Hospitals NHS Foundation Trust says a dietitian calculates the required daily amount for the modified ketogenic diet it describes.
What should you check?
Compare carbohydrate on the same per-100ml basis, then calculate the amount in the portion you expect to drink. After that, check the recipe, ingredients and any requirements of a prescribed diet.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate per portion | Read total carbohydrate per 100ml and calculate it for the amount you will drink. Check the portion size used on the label rather than relying on a no-added-sugar claim: Tesco Groceries lists 7.1g per 100ml and 14g per stated 200ml serving for the Mars drink. | I need the whole portion to fit my planned intake, not just a promising description on the bottle. |
| Preparation and recipe | Decide between a finished drink and a base you will blend yourself. Alpro UK lists 0g carbohydrate and 0.5g protein per 100ml for its Roasted Almond No Sugars Drink; calculate the ingredients added to the finished shake separately. | If I make a shake, I can choose its additions. If I need a drink without preparation, I need to assess the finished recipe and portion. |
| Ingredients and allergens | Read the current ingredient and allergen information for the exact variant. Asda Groceries lists milk and barley for the checked Mars drink; the checked Alpro drink is an almond product. | Milk, barley or almond may rule out a particular option for me, regardless of its carbohydrate figure. |
| Prescribed diet | Check the exact product and intended portion against the specialist plan. NHS Specialist Pharmacy Service says allowances for medical ketogenic diets vary with individual circumstances. | If I follow a prescribed ketogenic diet, I need to use my own plan rather than a general shopping label. |
Common buying mistakes
-
Taking “no added sugar” to mean no carbohydrate
Tesco Groceries lists 14g carbohydrate per stated 200ml serving for the checked no-added-sugar Mars Chocolate Flavoured Milk Drink.
Use the total carbohydrate line and calculate the amount in the portion you intend to drink.
-
Comparing different serving sizes as though they were equal
Per-100ml figures and figures for a larger portion answer different questions. Müller UK & Ireland lists 11.8g carbohydrate per 100ml for the checked FRijj Chilli Chocolate flavour; Tesco Groceries lists 14g per stated 200ml serving for the checked Mars drink.
Compare drinks per 100ml first, then calculate each intended portion.
-
Treating a drink base as a complete shake
Alpro UK lists 0g carbohydrate but 0.5g protein per 100ml for its Roasted Almond No Sugars Drink. Those figures describe the drink itself, not a shake made with additional ingredients.
Check the nutrition information for everything you blend into the base.
-
Using general keto advice for a prescribed diet
NHS Specialist Pharmacy Service says medical ketogenic-diet allowances vary between individuals. A low carbohydrate figure alone cannot establish whether a drink fits a particular prescription.
Check product changes and portion sizes with the dietitian or specialist team responsible for your plan.
Brand and product-line references
These nutrition figures refer to the named drinks and flavours, not every product made by each brand.
Alpro
The checked Roasted Almond No Sugars Drink is a plant-based base for a homemade shake, not a finished flavoured milkshake.
- Alpro UK lists 0g carbohydrate and 0g sugars per 100ml for this drink.
- Alpro UK lists 0.5g protein per 100ml; assess additions separately rather than treating the base as a complete shake.
Mars
The checked Chocolate Flavoured Milk Drink is a ready-to-drink option labelled no added sugar.
- The finished drink requires no blending.
- Tesco Groceries lists 7.1g carbohydrate per 100ml and 14g per stated 200ml serving. Asda Groceries lists milk and barley among its allergens.
Yazoo
The checked Banana and Kids Chocolate drinks have different carbohydrate declarations, so the variant matters.
- Yazoo lists 5.0g carbohydrate per 100ml for Kids Chocolate, which is labelled no added sugar.
- Yazoo lists 8.7g carbohydrate per 100ml for Banana. The no-added-sugar Kids Chocolate drink still lists carbohydrate and sugars.
Müller FRijj
The checked Chilli Chocolate flavour is a ready-to-drink flavoured milkshake.
- It offers a finished drink rather than a base that needs blending.
- Müller UK & Ireland lists 11.8g carbohydrate per 100ml for this flavour; check the specific variant and current pack when choosing a portion.

Alpro Almond No Sugars Long Life Drink, 8 x 1L
Use this almond drink as a base if you want to choose what goes into a homemade shake. It is not a finished milkshake; check the carbohydrate contribution of additions and the current pack information if you need to avoid almond.
No image available
Grenade Salted Caramel Protein Shake, 8 x 330ml
This ready-to-drink format avoids mixing. Check carbohydrate for the 330ml bottle against the amount you plan to drink, and read the current pack for milk and other ingredient information.

Applied Nutrition Diet Whey Vanilla Cream Protein Powder, 1.8kg
This powder is for a shake you prepare yourself rather than a ready-to-drink milkshake. Calculate the finished drink using both the powder portion and the liquid or other ingredients you add; check the current pack if you need to avoid milk.
Frequently asked questions
Does “no added sugar” mean a milkshake is keto-friendly?
No. A no-added-sugar claim does not mean zero carbohydrate. Tesco Groceries lists 7.1g carbohydrate per 100ml and 14g per stated 200ml serving for the checked no-added-sugar Mars drink, so compare the portion you will drink with your own requirements.
What should I check on a prepacked milkshake label?
Start with total carbohydrate per 100ml and calculate it for your intended portion, then check the ingredients and allergens for the exact product. Compare serving figures only when you know how much each serving contains.
Can an almond drink be the base of a homemade shake?
Yes, if its ingredients suit you and you account for everything added. Alpro UK lists 0g carbohydrate and 0g sugars per 100ml for its Roasted Almond No Sugars Drink; those figures do not describe a finished shake made with fruit, powders or flavourings.
Can a ready-to-drink shake fit a prescribed ketogenic diet?
Only if the exact product and portion fit the individual plan from the specialist team. NHS Specialist Pharmacy Service says medical ketogenic-diet allowances vary, so a general low-carbohydrate description cannot establish suitability for a prescription.
Which allergens matter in the checked drinks?
Asda Groceries lists milk and barley for the checked Mars Chocolate Flavoured Milk Drink. The checked Alpro base is an almond drink. Read the current ingredients and allergen information for the exact product you intend to buy.
