For a low-fat milkshake to drink with lunch, compare fat per 100ml with the 1.5g threshold for liquid ‘low fat’ claims described by GOV.UK, then check sugars, protein and the amount in the whole bottle. An ordinary flavoured milk or protein shake is a drink to have alongside food; a formulated meal replacement is a different choice for someone specifically following its preparation and use instructions. ‘No added sugar’ does not mean sugar-free.
Who is choosing?
Shoppers looking for a low-fat lunch drink
If you want chilled flavoured milk while working from home, the useful starting point is fat per 100ml. Flavour and front-of-pack wording alone cannot tell you whether the exact drink meets the liquid low-fat threshold described by GOV.UK.
Home workers comparing protein shakes
If protein matters to your lunch choice, compare both the per-100ml figure and the amount in the bottle. The protein shakes listed by Tesco Groceries are drinks to have alongside food, not products presented as complete meal replacements.
Shoppers considering a meal replacement
A formulated meal replacement serves a different purpose from an ordinary milkshake. Tesco Groceries describes Tesco Slim Chocolate as a product to prepare with skimmed milk for use within an energy-restricted diet; its instructions matter to that choice.
What should you check?
Start with the fat figure for the drink you will actually consume, then decide whether you want a small flavoured milk, a protein drink alongside food or a specifically formulated meal replacement.
| Priority | What to check | Your needs |
| Low-fat criterion |
Check fat per 100ml on the exact pack. GOV.UK describes no more than 1.5g per 100ml as the threshold for a liquid ‘low fat’ claim. Compare saturates separately. |
I want the drink to meet a low-fat requirement, rather than relying on its flavour or a ‘no added sugar’ label. |
| Role at lunch |
Compare protein per 100ml and per bottle. Check whether the product is an ordinary drink or a formulated meal replacement, and follow any preparation instructions for the latter. |
A drink alongside my lunch suits a different plan from deliberately using a labelled meal replacement. |
| Sugars and serving |
Read sugars per 100ml and the bottle or carton size; use the serving figure where supplied. ‘No added sugar’ is not the same as sugar-free: Tesco Groceries lists 4.7g sugars per 100ml for Yazoo No Added Sugar Chocolate. |
I want to know what the whole drink contains, not judge it from the front of the pack or a per-100ml figure alone. |
| Ingredients |
Read the current ingredient and allergen statement for milk, barley and sweeteners where relevant. Check a lactose-free statement on the exact variant rather than assuming it applies across a range. |
Milk or barley ingredients, lactose and sweeteners could change which product I choose. |
| Pack and handling |
Check the number of cartons, cans or bottles, the volume of each and the pack-specific directions after opening. |
A single drink at my desk and a multipack for several lunches call for different serving sizes and storage plans. |
What is easy to overlook?
-
Assuming ‘no added sugar’ means low fat
Tesco Groceries lists 2.2g fat per 100ml for Mars No Added Sugar Chocolate. That is above the 1.5g-per-100ml liquid low-fat threshold described by GOV.UK.
If low fat is your requirement, check fat per 100ml first. Compare sugars, saturates and protein separately on the pack you intend to buy.
-
Using an ordinary shake as the whole lunch
A protein figure does not make a flavoured milk or protein shake a formulated meal replacement. Tesco Groceries describes Tesco Slim Chocolate as a separate meal-replacement product with preparation and use instructions.
Plan other lunch foods with an ordinary shake. If you are choosing a meal replacement instead, check its intended use and preparation directions.
-
Applying one bottle’s nutrition values to a whole range
Tesco Groceries lists 1.3g fat per 100ml for the FRijj Chocolate 330ml product, but 1.9g per 100ml for a separate 471ml FRijj Chocolate listing. Only the former figure falls within the liquid low-fat threshold described by GOV.UK.
Compare the nutrition panel for the exact flavour and pack size, even when the brand and flavour name look familiar.
-
Skipping the ingredient statement
The compared dairy drinks contain milk, while Tesco Groceries also lists barley malt extract in the Mars chocolate drink. Lactose-free wording and sweetener ingredients vary by product.
Check the current pack’s ingredient and allergen information against your requirements; do not use a lactose-free statement as a substitute for checking for milk.
Brand and product-line references
These examples show why the exact product matters: a low-fat figure, a no-added-sugar label and a meal-replacement designation answer different questions.
For Goodness Shakes
The Protein Chocolate 330ml drink is a ready-to-drink protein-shake example.
- Tesco Groceries lists 0.3g fat and 10.6g protein per 100ml, and 35g protein per bottle.
- It is a milk-based drink with sweetener, not a product presented as a complete meal replacement.
Arla Protein
The Vanilla milkshake offers a lactose-free protein-drink route for someone comparing lunch accompaniments.
- Tesco Groceries lists 0.9g fat and 5.7g protein per 100ml, with 26g protein per bottle.
- It contains milk. Its listed 4.7g sugars per 100ml are worth comparing with the amount in the whole bottle.
Yazoo
No Added Sugar Chocolate is an ordinary flavoured milk drink sold in 200ml cartons, rather than a meal replacement.
- Tesco Groceries lists 1.4g fat per 100ml, within the liquid low-fat threshold described by GOV.UK.
- Its no-added-sugar label does not mean sugar-free: the listed sugars figure is 4.7g per 100ml.
FRijj
FRijj Chocolate illustrates why a low-fat decision cannot be made from a brand name alone.
- Tesco Groceries lists 1.3g fat per 100ml for the 330ml Chocolate product.
- A separate 471ml Chocolate listing gives 1.9g fat per 100ml. Check the exact bottle; the two listings sit on opposite sides of GOV.UK’s stated liquid low-fat threshold.
Mars
The No Added Sugar Chocolate drink shows that sugar wording and fat content need separate checks.
- Tesco Groceries identifies a no-added-sugar 400ml chocolate-flavoured milk drink.
- It lists 2.2g fat per 100ml, above GOV.UK’s stated liquid low-fat threshold, and its ingredients include milk and barley malt extract.
Tesco Slim
Tesco Slim Chocolate is a powdered, formulated meal replacement to make with skimmed milk as directed, not a conventional ready-to-drink milkshake.
- Tesco Groceries lists 200kcal for one serving prepared with 250ml skimmed milk.
- The prepared serving lists 4.8g fat in 250ml, equivalent to about 1.9g per 100ml—above GOV.UK’s stated liquid low-fat threshold. Tesco describes it for use within an energy-restricted diet, not as a total diet replacement.

Common questions
What does ‘low fat’ mean for a liquid milkshake?
GOV.UK describes no more than 1.5g fat per 100ml as the threshold for a liquid ‘low fat’ claim. Check fat per 100ml on the exact product rather than comparing bottle totals or assuming every flavour in a range has the same recipe.
Is a no-added-sugar milkshake sugar-free?
No. A no-added-sugar product can still list sugars: Tesco Groceries gives 4.7g per 100ml for Yazoo No Added Sugar Chocolate and 6.5g per 100ml for Mars No Added Sugar Chocolate. Read the sugars figure for the exact drink and serving size.
Can a low-fat milkshake replace lunch?
An ordinary flavoured milk or protein shake is not automatically a formulated meal replacement. If you specifically want a meal replacement, check its designation and instructions: Tesco Groceries describes Tesco Slim Chocolate for use within an energy-restricted diet, prepared with skimmed milk, and says it should not be used as a total diet replacement.
Which ingredients should I check before buying?
Check the current ingredient and allergen statement for the exact variant. The compared dairy drinks contain milk, Tesco Groceries lists barley malt extract in the Mars chocolate drink, and lactose-free wording or sweeteners vary between products.
