If you intend to replace a planned meal, choose a shake explicitly labelled for meal replacement and follow its preparation and use directions. Treat a protein drink or ordinary flavoured milkshake as a drink rather than assuming its protein content or sugar wording makes it a meal replacement. Compare nutrition for the amount you will actually consume.
The intended role of the drink matters more than whether it is sold as a shake or milkshake.
Look for an explicit meal-replacement statement and check how to prepare and use the serving. Tesco Groceries describes Tesco Slim Chocolate as a meal replacement shake for weight control; its SlimFast Chocolate listing also identifies a meal-replacement powder.
A protein milkshake may suit someone who wants a drink or snack without preparing a powder. Tesco Groceries lists 20g protein for Shaken Udder Chocolate Protein Milkshake, but protein content alone does not establish that a drink is intended to replace a meal.
For a drink such as Yazoo, FRijj or Mars, compare the nutrition panel with the portion you expect to drink. Check sugars as well as any no-added-sugar wording, and do not assume a flavoured milk drink has meal-replacement directions.
Decide whether the shake is replacing a meal or accompanying one, then compare labels on a consistent serving basis.
Choose when: You plan to substitute a meal and can follow the product’s stated directions.
Bear in mind: A powder’s prepared serving depends on how you make it; meal replacement is not the same as using a shake as your only food.
Choose when: You want a protein drink without mixing a powder.
Bear in mind: Protein content does not, by itself, tell you whether the drink is intended to replace a meal.
Choose when: You want a flavoured drink and can account for the portion you consume.
Bear in mind: A no-added-sugar label does not mean the drink contains no sugars.
| Priority | What to check | Your needs |
|---|---|---|
| Intended use | Read the product’s meal-replacement statement and use directions. Check whether it is intended for a planned meal substitution rather than as a drink alongside a meal. | If I am replacing a meal, I want a product explicitly labelled for that purpose and directions I can follow. |
| Portion and energy | Compare kcal per prepared serving or ready-to-drink portion. Check the container size and number of stated servings before counting a whole bottle. | I want to account for the amount I will drink, especially if the bottle contains more than one serving. |
| Protein and fibre | Compare stated grams on the same serving basis. Check intended use separately; a protein figure does not identify a meal replacement. | Protein or fibre may matter to my comparison, but I do not want either figure to stand in for the product’s use directions. |
| Sugars and ingredients | Read sugars per serving or per 100ml alongside the portion size. Check the ingredients if sweeteners or particular allergens matter to you. | If a drink says no added sugar, I still want to know what its nutrition panel says about sugars in the portion I will have. |
| Preparation | For a powder, check the specified amount and type of liquid and whether nutrition values refer to the powder or the prepared drink. | I need a serving comparison that reflects how I will actually make the shake. |
Tesco Groceries lists the Mars No Added Sugar milk drink as containing naturally occurring sugars. The phrase does not establish its calorie content or intended role in a meal plan.
Check sugars and energy on the nutrition panel for the portion you intend to drink.
Tesco Groceries lists 20g protein for a Shaken Udder protein milkshake. That figure describes one nutrient, not whether the drink is intended for meal substitution.
Check the product’s intended-use statement, serving size and full nutrition panel before deciding how to use it.
A powder’s stated serving may refer to a prepared drink, while a bottled drink may show values per 100ml and per serving. Comparing those figures without their preparation and portion details can misrepresent the amount consumed.
Use the labelled preparation directions and compare the servings you actually plan to have.
Müller UK & Ireland advises checking product labelling because its products can change. An older listing may not describe the pack you receive.
Check the current pack for ingredients, allergens, serving size and nutrition information.
These examples illustrate different product types; the figures and statements apply to the named products, not every drink from each brand.

This meal-replacement powder is relevant if you plan to substitute a meal. Check the current pack’s preparation method and which prepared serving its nutrition figures describe before comparing it with a ready-to-drink shake.

This 220ml yoghurt drink fits the flavoured-drink comparison rather than an assumed meal-replacement role. Check the current ingredients and sugars panel, particularly if sugar wording on the pack affects your choice.
Do not assume that it can. If meal substitution is your aim, choose a product explicitly labelled as a meal replacement and follow its preparation and use directions. Tesco Groceries identifies Tesco Slim Chocolate as a meal replacement shake for weight control; a flavoured milk drink’s name or nutrient figures do not establish the same intended use.
No. Tesco Groceries notes that its Mars No Added Sugar milk drink contains naturally occurring sugars. Read the sugars figure for the portion you intend to drink, rather than treating the phrase as a statement about all sugars or calories.
Use per-100ml figures to compare ready-to-drink products on the same volume basis, then use the serving or bottle size to assess the amount you expect to consume. For a powder, check whether its stated nutrition refers to the prepared drink.
No. Protein is one part of the nutrition panel, not an intended-use statement. Tesco Groceries lists 20g protein for Shaken Udder Chocolate Protein Milkshake; check a product’s labelling and directions before using any shake to replace a planned meal.
