A small bag of crisps can be a convenient savoury snack before a routine workout if you have already eaten enough, but do not rely on it alone when you need a snack to provide substantial carbohydrate. The labelled single bags discussed here contain carbohydrate alongside fat and salt; compare the amount in the bag you will eat, and consider a more carbohydrate-led food when fuelling the session is the main aim.
A single bag is easy to take along when you want something savoury rather than a snack to supply most of your exercise fuel. Check its carbohydrate, fat and salt per bag before deciding whether it fits what you need.
If you intend to eat the whole bag, its labelled serving size makes the nutrition figures easier to use than those on an open sharing pack. Seabrook labels Sea Salted Crunchies as an 18 g bag; the Walkers and Tyrrells products discussed below have different serving sizes.
Compare the exact flavour and pack. Walkers labels its 25 g Lightly Salted bag at 0.17 g salt and its 25 g Ready Salted bag at 0.34 g; ingredients and allergen statements also differ between products.
Decide whether you want a convenient savoury snack or food to contribute carbohydrate for the session, then compare the nutrition for the portion you will actually eat.
Consider when: you mainly want a portable savoury snack and have eaten adequately earlier.
Trade-off: a small bag still contributes fat and salt as well as carbohydrate, so portion size alone does not tell you how it fits your plans.
Consider when: you are choosing the snack chiefly for carbohydrate before a longer or harder session.
Trade-off: it will not answer a craving for crisps; compare the actual food and portion rather than assuming every alternative has the same nutrition. The UK Sports Institute notes that carbohydrate needs vary with exercise intensity and duration.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate | Read carbohydrate per bag, not just per 100 g. Seabrook labels its 18 g Sea Salted Crunchies bag at 12.6 g; Walkers labels its 25 g Ready Salted bag at 13 g. | If I am counting on this snack for carbohydrate before a longer or harder session, I need to consider whether a crisp bag serves that purpose. The UK Sports Institute says carbohydrate needs rise with exercise intensity and duration. |
| Portion size | Check the pack weight and number of servings. The labelled examples include an 18 g Seabrook Crunchies bag, 25 g Walkers bags and a 40 g Tyrrells Lightly Sea Salted single serving. | I want to know what I will eat in one sitting, rather than compare a whole grab bag with the per-100-g figures on a sharing pack. |
| Fat and salt | Compare both figures per bag. Walkers lists 7.8 g fat and 0.17 g salt for Lightly Salted 25 g, versus 7.7 g fat and 0.34 g salt for Ready Salted 25 g. | Lower labelled salt in one flavour does not tell me its fat content. I want to check each figure against the portion I plan to eat. |
| Ingredients | Read the exact flavour’s ingredients and allergen statement. Walkers says its Ready Salted crisps are made in a factory handling several allergens; McCoy’s lists barley malt vinegar extract in Salt & Malt Vinegar. | If an ingredient or allergen matters to me, I need the label for this flavour and pack, not an assumption based on the brand. |
Walkers labels a 25 g Ready Salted bag at 13 g carbohydrate and 7.7 g fat, while Seabrook labels an 18 g Sea Salted Crunchies bag at 12.6 g carbohydrate and 3.0 g fat. Being potato-based does not tell you how much carbohydrate a bag provides.
Decide whether you mainly want a savoury snack or are choosing food for its carbohydrate. If it is the latter, compare a more carbohydrate-led option rather than relying on crisps alone.
Single servings vary: the labelled Seabrook Crunchies bag is 18 g, the Walkers bags are 25 g and Tyrrells Lightly Sea Salted has a 40 g pack labelled as one serving.
Use the per-bag nutrition and serving count when choosing between grab bags.
Walkers Lightly Salted lists less salt than Walkers Ready Salted in their labelled 25 g portions, but the Lightly Salted bag still lists 7.8 g fat.
Check salt and fat separately, and compare the precise flavour and serving size.
Walkers provides labelled 25 g single-bag figures for Ready Salted and Lightly Salted.
Seabrook labels Sea Salted Crunchies as an 18 g bag and Sea Salted potato crisps as a 31.8 g bag.
Tyrrells labels its Lightly Sea Salted 40 g pack as one serving.
KETTLE Chips publishes per-100-g nutrition for Lightly Salted on a sharing-format product page.
McCoy’s publishes ingredients and per-100-g nutrition for Salt & Malt Vinegar Flavour.
REAL publishes per-100-g figures for Sea Salt & Black Pepper.
These multipacks contain individual bags for shoppers considering a savoury snack before exercise. Compare each bag’s labelled nutrition and ingredients if you need more than a convenient portion; the products are not a comparison of every possible pre-workout snack.

Six individual 24 g bags offer a defined Cheese & Onion portion. Check the flavour’s ingredients and allergen statement, as well as its per-bag carbohydrate, fat and salt, before choosing it for a pre-workout snack.
It can be a convenient savoury snack if you have eaten adequately earlier, but do not assume it supplies all the carbohydrate you want from food before exercise. The UK Sports Institute notes that carbohydrate needs increase with exercise intensity and duration; check the bag’s carbohydrate alongside its fat and salt.
Seabrook Sea Salted Crunchies is labelled as an 18 g bag, with 82 kcal, 3.0 g fat, 12.6 g carbohydrate and 0.3 g salt. The Walkers examples have 25 g bags, while Tyrrells labels its Lightly Sea Salted 40 g pack as one serving.
Yes, for the labelled 25 g servings compared here: Walkers lists 0.17 g salt for Lightly Salted and 0.34 g for Ready Salted. That comparison applies to those products and serving sizes, not every Walkers flavour.
Read the ingredients and allergen statement for the exact flavour and pack. For example, McCoy’s lists barley malt vinegar extract in Salt & Malt Vinegar Flavour and says it may contain milk, soya, gluten and mustard; Walkers says its Ready Salted crisps are made in a factory handling several allergens.
Do not treat personal purchase and food provided by a school as the same question. The Department for Education states that school food standards are a legal requirement for state-funded schools in England; Gateshead Council’s guidance says snacks are restricted to nuts, seeds, vegetables and fruit with no added salt, sugar or fat. Check the applicable school-food requirements before supplying snacks, and do not extend this England-specific guidance to every UK nation or describe it as a general ban on buying crisps.
