Day hikers considering a drink snack
You want a low-fat drink in a pack that fits your route, without treating it as a replacement for the water you plan to carry.
Who this is for
Shoppers comparing label claims
You want to compare fat, sugars and energy on the exact flavour’s nutrition panel rather than assume that a no-added-sugar drink is also low in fat.
Buyers checking dairy suitability
You need to read the allergen declaration on the exact pack. Lactose-reduced dairy still contains milk and is not a milk-free option.
What to check before buying
Start with fat per 100 ml, then check whether the pack size and storage instructions work for your walk.
| Priority | What to check | Your needs |
|---|---|---|
| Fat content | Read fat per 100 ml on the exact flavour. The UK low-fat claim condition for liquids is no more than 1.5 g per 100 ml, according to legislation.gov.uk; do not use a no-added-sugar claim as a substitute. | I want a drink that meets the low-fat condition, even if another flavour from the same brand has a different recipe. |
| Storage and pack size | Check whether the unopened drink can be kept in a cool, dry place or must be refrigerated. Choose a pack size you can finish and follow its instructions after opening. | A smaller pack may suit a solo walk; if I choose a larger carton or a chilled drink, I need a plan for carrying and storing it. |
| Sugars and energy | Compare sugars and energy per 100 ml, then consider how much you expect to drink. Low fat and no added sugar describe different things. | I want the amount I drink to fit my plans for the day, rather than judging the snack by its fat figure alone. |
| Allergens and water | Read the exact pack’s milk and other allergen declarations. Plan water separately: the British Mountaineering Council advises hill walkers to bring plenty of water. | Milk suitability matters to me, and I do not want a milkshake to take the place of the water I carry for the route. |
Mistakes to avoid
-
Assuming no added sugar means low fat
Tesco Groceries lists 2.2 g fat per 100 ml for its Mars No Added Sugar chocolate milk drink. That exceeds the 1.5 g-per-100-ml low-fat condition for liquids published by legislation.gov.uk.
Check fat per 100 ml on the nutrition panel first, then compare sugars and energy separately.
-
Packing a chilled drink without a way to keep it cold
Tesco’s 1 L chocolate flavoured milk reaches 1.5 g fat per 100 ml, but its product instructions say to keep it refrigerated. Meeting the fat condition does not change its storage requirements.
Follow the exact pack instructions. For a walk without cold storage, look for an unopened drink whose label permits storage in a cool, dry place.
-
Choosing a litre carton for a solo snack without considering the route
A 1 L carton takes more pack space than a 200–400 ml drink. The British Mountaineering Council notes that walk duration, weather and pack weight affect snack choices.
Match the pack size to the people drinking it and to whether you can store any remainder as instructed.
-
Treating lactose-reduced as milk-free
The lactose-reduced Yazoo chocolate carton described by ASDA Groceries still contains milk. The NHS distinguishes lactose intolerance from food allergy.
If milk is an allergen for you, check the exact product’s allergen declaration rather than relying on its lactose wording.
Brand and product-line references
These examples illustrate differences between specific drinks; check the flavour and pack you intend to take.
Arla Protein
The 1 L chocolate milk shake is an option to compare if a larger carton suits the walk.
- ASDA Groceries lists 0.9 g fat and 5.7 g protein per 100 ml, with cool, dry storage before opening.
- The 1 L carton contains milk and needs refrigeration after opening.
Yazoo
The examined flavoured-milk packs range from a 200 ml carton to a 1 L drink, so size and formulation need checking separately.
- ASDA Groceries lists 1.1 g fat per 100 ml for the examined strawberry 400 ml and banana 1 L drinks, and 1.4 g for the examined chocolate 200 ml carton.
- The lactose-reduced chocolate carton still contains milk; compare its sugars with those of the exact alternative you are considering.
Müller Frijj
The examined banana milkshake comes in a 330 ml bottle.
- Sainsbury’s lists 1.4 g fat per 100 ml for this banana variant.
- The same listing gives 10 g sugars per 100 ml; low fat does not describe its sugar content.
Mars
The examined 400 ml chocolate milk drink shows why no added sugar is a separate check from low fat.
- Tesco Groceries identifies this variant as having no added sugar.
- Tesco lists 2.2 g fat per 100 ml, above the UK low-fat condition for liquids published by legislation.gov.uk; the drink contains milk and barley.
Tesco
The examined 1 L chocolate flavoured milk is a chilled option, not an ambient-storage trail drink.
- Tesco Groceries lists 1.5 g fat per 100 ml, at the UK low-fat limit for liquids published by legislation.gov.uk.
- Its instructions say to keep it refrigerated, including after opening.

Common questions
What counts as a low-fat milkshake in the UK?
For a liquid to carry a low-fat claim, it must contain no more than 1.5 g fat per 100 ml under the condition published by legislation.gov.uk. Check the exact flavour’s nutrition panel rather than applying one variant’s figure to a whole range.
Can I pack an unopened UHT milkshake for a hike?
Yes, if the exact pack permits storage in a cool, dry place and you follow those instructions. Check what it requires after opening and choose a size you can finish rather than carrying opened dairy drink for the rest of the walk.
Can a chilled milkshake stay in my rucksack all day?
Do not treat a chilled-only drink as suitable for an unrefrigerated day out. Tesco’s examined chocolate flavoured milk says to keep it refrigerated; take a chilled product only when you can follow its storage and use-by instructions throughout the journey.
Does no added sugar mean low fat?
No. Tesco Groceries lists its Mars No Added Sugar chocolate milk drink at 2.2 g fat per 100 ml, above the UK low-fat condition for liquids published by legislation.gov.uk. Compare fat and sugars as separate entries on the exact product’s nutrition panel.
Is a lactose-reduced milkshake milk-free?
No. The lactose-reduced Yazoo chocolate carton listed by ASDA Groceries still contains milk. If milk is an allergen for you, check the exact pack’s ingredient and allergen declaration; lactose-reduced wording does not make a dairy drink milk-free.
