People choosing a lower-fat crisp
If you want crisps after exercise while keeping crisp fat lower, compare the stated portion as well as the per-100 g figure. Consider what else will make up the snack or meal.
Who is this choice for?
People comparing protein in crisp-style snacks
Lentil crisps can contribute more protein per serving than the checked baked potato crisps. The difference needs to be weighed against their fat and salt declarations and the amount you plan to eat.
People checking salt or allergens
A lower-fat claim does not answer a salt or allergen question. Compare the nutrition panel and ingredient statement for the exact flavour and pack.
What should you compare?
Start with the type of snack you want, then compare fat, protein and salt on the same basis before checking the portion you would actually eat.
| Priority | What to check | Your needs |
|---|---|---|
| Fat | Compare fat per 100 g across packs, then fat per serving. Walkers UK lists 2.8 g per 22 g pack for Oven Baked Sea Salt; Tyrrells lists 6.0 g per 30 g serving for a checked lentil variety. | I want a savoury crisp after exercise, with fat reduction taking precedence over how much protein the crisps themselves provide. |
| Protein | Check protein and carbohydrate per serving. Walkers UK lists 1.3 g protein and 16 g carbohydrate per Oven Baked Sea Salt pack; Tyrrells lists 3.9 g protein and 17 g carbohydrate per 30 g serving for a checked lentil variety. | If I want both carbohydrate and protein in the snack, I can add a protein-containing food rather than relying on the crisps alone. University College London Hospitals NHS Foundation Trust describes that combination in its exercise-snack guidance. |
| Salt | Read salt per serving alongside fat. Walkers UK lists 0.17 g salt but 7.8 g fat per 25 g serving for Lightly Salted; it is a salt-reduction choice, not the same product as Oven Baked. | Salt matters to me too, so I do not want to choose by a lower-fat or lower-salt claim without checking both figures. |
| Ingredients | Check the ingredient list, declared allergens and precautionary wording for the exact flavour. Do not transfer a dietary claim from one product to another. | I need to know whether this particular pack fits my ingredient or allergen requirements, especially when switching flavours or formats. |
What is easy to overlook?
-
Assuming reduced fat makes a complete post-exercise snack
The checked Walkers Oven Baked Sea Salt pack has 1.3 g protein, while a checked Tyrrells Lentil serving has 3.9 g. University College London Hospitals NHS Foundation Trust describes snacks combining carbohydrate and protein for use around exercise.
If that combination is your aim, have the crisps with a protein-containing food or as part of a meal.
-
Comparing unlike pack sizes
A 22 g baked-crisp pack and a 30 g lentil-crisp serving do not give directly comparable per-pack figures.
Use per-100 g declarations to compare products, then check the figures for the quantity you expect to eat.
-
Equating lower salt with lower fat
Walkers UK lists 0.17 g salt and 7.8 g fat per 25 g serving for Lightly Salted. Its salt claim does not make it the same choice as Oven Baked for reducing crisp fat.
Decide which nutrient matters for this purchase and read both values on the exact pack.
-
Extending a dietary claim to every flavour
Ingredients and allergen statements can differ between crisp products. REAL Roast Ox, for example, lists milk-derived lactose, soya and celery in its flavouring.
Check the current ingredient and allergen wording for the flavour you intend to buy.
Brand and product-line references
These examples describe specific products and ranges; a brand name alone does not establish the nutrition or ingredients of another flavour.
Walkers
Oven Baked Sea Salt and Lightly Salted address different buying priorities.
- Walkers UK lists 2.8 g fat per 22 g pack for Oven Baked Sea Salt and states that it has 50% less fat than regular potato crisps.
- Lightly Salted lists 0.17 g salt but 7.8 g fat per 25 g serving; a lower-salt claim should not be read as a lower-fat claim.
Tyrrells
The checked lentil crisps offer a different fat-and-protein balance from Walkers Oven Baked Sea Salt.
- Tyrrells lists 3.9 g protein and 6.0 g fat per 30 g serving for a checked lentil variety.
- Tyrrells’ reduced-fat comparison uses an average of standard potato crisps reviewed in March 2021, not every crisp currently sold.
KETTLE Chips
The checked Sea Salt & Balsamic Vinegar product provides an example of a hand-cooked potato crisp rather than a reduced-fat choice.
- KETTLE Chips labels this product gluten-free and suitable for vegans and vegetarians.
- Its declaration lists 28.9 g fat and 1.6 g salt per 100 g; check the exact product when comparing varieties.
Seabrook
Sea Salted is a standard crinkle-cut potato crisp with a stated bag and per-100 g declaration.
- Seabrook lists 9.7 g fat and 0.4 g salt per 31.8 g bag.
- Its per-100 g declaration lists 30.4 g fat, so use the same measurement basis when comparing it with baked or lentil options.
McCoy's
The checked Salted product is a ridged potato crisp, not a stated reduced-fat format.
- McCoy's provides a per-100 g declaration for Salted, allowing a like-for-like label comparison.
- That declaration lists 32 g fat and 1.3 g salt per 100 g; other flavours require their own checks.
REAL Hand Cooked Crisps
Range-level dietary claims still leave flavour-specific ingredients and nutrition to check.
- REAL states that its range is vegetarian and gluten-free.
- Roast Ox lists lactose, soya and celery in its flavouring, along with 25.7 g fat per 100 g.

Consider these lentil cakes if you are open to a cake rather than a crisp. Check the stated serving’s protein, fat and ingredients instead of treating the product name as a nutrition comparison.
Common questions
Are reduced-fat crisps enough as a post-exercise snack?
That depends on what else you eat with them. Walkers UK lists 1.3 g protein per 22 g Oven Baked Sea Salt pack, and Tyrrells lists 3.9 g per 30 g serving for a checked lentil variety. If you want the carbohydrate-and-protein combination described in University College London Hospitals NHS Foundation Trust’s exercise-snack guidance, include a protein-containing food.
Should I choose baked potato crisps or lentil crisps?
Choose according to the nutrient you are comparing. Walkers Oven Baked Sea Salt has 2.8 g fat and 1.3 g protein per 22 g pack; a checked Tyrrells Lentil serving has 6.0 g fat and 3.9 g protein per 30 g. Compare their per-100 g panels as well as your intended portion because the stated servings differ.
Does lower salt also mean lower fat?
No. Walkers UK lists 0.17 g salt and 7.8 g fat per 25 g serving for Lightly Salted. Check both values rather than using its salt claim to judge fat content.
How do I check whether a crisp flavour fits my allergen requirements?
Read the ingredient and precautionary allergen statements for the exact product and flavour. For example, REAL lists milk-derived lactose, soya and celery in its Roast Ox flavouring; a range-level vegetarian or gluten-free claim does not answer every allergen question.
Do vegan or gluten-free claims tell me whether crisps are reduced fat?
No. KETTLE Chips labels its Sea Salt & Balsamic Vinegar product vegan and gluten-free, while its nutrition declaration lists 28.9 g fat per 100 g. Check dietary claims and the nutrition panel separately for the product you intend to buy.
