For a drink alongside an office packed lunch, choose between standard and no-added-sugar flavoured milk by checking the ingredients, total sugars and amount you expect to drink; “no added sugar” does not mean sugar-free. If you intend to replace lunch as part of a weight-control plan, look for a product explicitly labelled for meal replacement and follow its stated use conditions rather than relying on a conventional milkshake’s protein content.
A flavoured milk drink can accompany lunch, but a no-added-sugar claim and the total-sugars figure answer different questions. The NHS explains that sugars naturally present in milk appear in total sugars but are not free sugars.
If sandwiches, a salad or other food make up lunch, choose the drink by its ingredients, portion size and practicality. Protein content alone does not make a conventional flavoured milkshake a meal replacement.
If the intention is a meal replacement within a weight-control plan, check that the product is labelled for that purpose and read its stated diet conditions. An ordinary flavoured milk drink serves a different purpose.
Decide whether the shake is a drink with lunch or an intended meal replacement, then compare the exact variant’s label and the amount you will consume.
| Priority | What to check | Your needs |
|---|---|---|
| Added and total sugars | Check the no-added-sugar claim, ingredients and sugars per 100ml and per bottle. The NHS distinguishes free sugars from naturally occurring milk sugars, which still appear in total sugars. | I want to reduce added sugar without assuming the drink contains no sugar. If I also avoid sweeteners, I need to read the ingredients. |
| Drink or meal replacement | Look for an explicit meal-replacement label and its use conditions if you plan to replace lunch. Sainsbury’s describes its cited SlimFast shake as a meal replacement for weight control, with use tied to a calorie-controlled varied diet and active lifestyle; protein content alone does not establish that purpose. | Am I packing a drink to go with food, or deliberately replacing the meal? That decision changes which product category I should consider. |
| Ingredients and allergens | Read the exact variant’s ingredient and allergen declarations. Tesco lists milk, barley and sweeteners for its cited Mars no-added-sugar drink; Yazoo says its Kids Chocolate variant has no artificial sweeteners, but it remains milk-based. | Milk, barley or sweeteners may affect which variant I choose, regardless of the claim on the front of the bottle. |
| Amount consumed | Compare figures on the same basis and check bottle size. Tesco lists the Mars drink as 400ml and gives sugars per 100ml; the per-100ml figure is not the amount in the whole bottle. | If I expect to finish the bottle at lunch, I want to assess that amount rather than a smaller labelled portion. |
| Preparation and storage | Check whether the drink is ready to consume or needs milk and a cup. Tesco says to refrigerate its cited Mars drink after opening and consume it within three days; Sainsbury’s says its cited Crusha mix must be refrigerated after opening and used within one month. | For a desk lunch, I need a format I can prepare and store according to its own label. |
A milk-based drink can still show sugars on its nutrition panel. The NHS explains that naturally occurring milk sugars count towards total sugars but not free sugars; some no-added-sugar drinks also contain sweeteners.
Check the sugars figure for the amount you will drink, then read the ingredients if added sugars or sweeteners matter to you.
Protein or calcium information on a conventional flavoured milkshake does not establish that it is intended as a meal replacement.
If you plan to replace lunch, choose a product explicitly labelled for that use and check its stated diet conditions. Otherwise, consider the milkshake as the drink or treat alongside your packed food.
A per-100ml value is useful for comparing labels, but it does not describe the amount you consume if you finish a larger bottle.
Check the bottle volume and use the full-bottle or relevant serving figures for energy and sugars.
Milk, barley, sweeteners and preparation requirements differ between the cited products. Instructions after opening also depend on the format.
Read the ingredients, allergen statement and storage directions on the exact flavour and size you buy.
Claims about sugar and sweeteners apply to the named variants, not every drink sold under a brand.
Yazoo sells standard flavoured milk drinks as well as a Kids Chocolate no-added-sugar variant.
The cited FRijj Chocolate is a conventional, ready-to-drink dairy milkshake in a 330ml bottle.
The cited Mars Chocolate Flavoured Milk Drink is a 400ml ready-to-drink, no-added-sugar variant.
This ready-to-drink option is for someone planning to replace an office lunch with a shake, rather than choosing a flavoured milk drink to accompany food.

This ready-to-drink chocolate complete-meal shake is an option for a planned lunch replacement and comes as four 500ml bottles. Check the bottle’s sugar, sweetener and allergen information, and follow its meal-use directions rather than using it to replace an otherwise varied diet.
No. The NHS explains that naturally occurring milk sugars appear in total sugars on food labels but are not free sugars. Tesco lists 6.5g sugars per 100ml for its cited Mars no-added-sugar milk drink, so check both the claim and the nutrition panel.
Do not treat its protein content as a meal-replacement label. A conventional flavoured milkshake can be the drink or treat alongside lunch; if you intend a weight-control meal replacement, choose a product labelled for that purpose and follow its stated diet conditions.
Read the ingredients on the exact variant. Tesco lists sweeteners for its cited Mars no-added-sugar drink, and Sainsbury’s describes its cited Crusha no-added-sugar mix as a product with sweeteners; Yazoo says its Kids Chocolate variant contains no artificial sweeteners. Confirm the label on the pack you buy.
Follow that product’s label. Tesco says to refrigerate its cited Mars ready-to-drink bottle after opening and consume it within three days; Sainsbury’s says to refrigerate its cited Crusha syrup after opening and use it within one month. Those instructions should not be applied to other drinks.
No. The claim concerns added sugar, not allergens. The cited Mars drink contains milk and barley, while the cited Yazoo and FRijj drinks are milk-based; check the allergen statement on the exact product before choosing it.
