Gym-goers comparing snack portions
A labelled packet makes it easier to see how much you plan to eat. Compare its calories with the per-100g figure before assuming that a smaller bag contains a less energy-dense crisp.
Who is this choice for?
People who need quick refuelling
After demanding exercise or when training again soon, consider the crisp packet alongside the rest of your food and drink. The British Dietetic Association advises carbohydrate-rich food and fluids when quick recovery is needed.
Snack buyers checking salt or allergens
Calories are only one label detail. Check salt, ingredients and allergen statements on the exact flavour and pack you intend to buy.
What should you compare?
| Priority | What to check | Your needs |
|---|---|---|
| Portion and calories | Read kcal per packet and the packet weight. Compare kcal per 100g separately so different serving sizes do not obscure the difference between products. | I want to know what one packet contains without mistaking a smaller portion for a less energy-dense crisp. |
| Food after exercise | Check what the serving contributes rather than judging it by calories alone. Seabrook lists 0.7g protein per Crunchies bag; Tyrrells lists 3.9g per 30g Sour Cream & Onion Lentil Crisps serving. | If I need quick recovery after demanding exercise, I will consider what else I am eating and drinking. The British Dietetic Association advises carbohydrate-rich food and fluids when quick recovery is required. |
| Salt | Compare salt per serving as well as per 100g. Seabrook lists 0.39g per 18g Salt & Vinegar Crunchies bag and 2.18g per 100g; Walkers lists 0.19g per 22g Oven Baked Sea Salt packet. | A packet that suits my calorie comparison may not suit what I am looking for in the salt line, so I want to check both. |
| Ingredients and suitability | Read the current ingredients, allergen statement and any dietary-suitability wording for the exact flavour. A claim about a range does not replace the label on an individual pack. | If I avoid an ingredient or need a particular dietary option, I need to check the pack I am buying rather than choose by crisp format. |
Common buying mistakes
-
Choosing by packet calories alone
Seabrook lists 81 kcal for an 18g Crunchies bag and 448 kcal per 100g. Walkers lists 96 kcal for a larger 22g Oven Baked Sea Salt packet but 438 kcal per 100g.
Use the packet figure to compare the portions you might eat and the per-100g figure to compare the crisps themselves.
-
Treating a crisp packet as the whole recovery snack
The cited Seabrook Crunchies bag provides 0.7g protein, while Tyrrells lists 3.9g per serving of Sour Cream & Onion Lentil Crisps. The British Dietetic Association advises carbohydrate-rich food and fluids when quick recovery is needed.
After demanding or repeated exercise, consider the packet as one part of what you plan to eat and drink, rather than assuming it covers your recovery needs.
-
Assuming a smaller or lentil-based pack has less salt
Salt figures use different serving sizes: Seabrook lists 0.39g per 18g Crunchies bag, while Tyrrells lists 0.60g per 30g Sour Cream & Onion Lentil Crisps serving.
Check salt per serving for the amount you intend to eat and per 100g when comparing products.
Brand and product references
Walkers
Oven Baked Sea Salt is a labelled 22g packet option for comparing portions.
- Walkers lists 96 kcal and 1.3g protein per packet, and 438 kcal per 100g.
- Those figures describe Oven Baked Sea Salt, not every flavour in the range.
Seabrook
Its Crunchies and standard Sea Salt products illustrate why packet size matters.
- Seabrook lists 81 kcal for an 18g Salt & Vinegar Crunchies bag.
- Its standard Sea Salt product is a different portion: 164 kcal per 31.8g bag, according to Seabrook.
Tyrrells
The Sour Cream & Onion Lentil Crisps provide a point of comparison for a lentil-based snack.
- Tyrrells lists 3.9g protein per 30g serving.
- The same serving lists 141 kcal and 0.60g salt; compare those figures with the portion you intend to eat.
KETTLE Chips
Lightly Salted is a potato-crisp reference for shoppers comparing labels and dietary-suitability statements.
- KETTLE labels this product gluten-free and suitable for vegans.
- KETTLE lists 516 kcal per 100g for Lightly Salted; check the weight of the portion you plan to eat.
McCoy's
Salted is a ridged potato-crisp reference rather than a smaller-packet comparison.
- McCoy's provides per-100g nutrition figures for its Salted flavour.
- Its Salted flavour lists 533 kcal and 1.3g salt per 100g; use the pack weight to assess your portion.
REAL Hand Cooked Crisps
Sea Salt offers another hand-cooked potato-crisp label for comparison.
- REAL states that its range is vegetarian and gluten-free; check the current pack if either matters to you.
- REAL lists 515 kcal and 1.3g salt per 100g for Sea Salt.
Crisp options on Joybuy
These Joybuy options include small multipack bags, a 30g vegetable-crisp pack and a larger lentil-chip bag. Use each product’s own label to compare the portion you intend to eat; the Walkers Sea Salt figures elsewhere in this article do not describe every flavour in a variety pack.

Questions about post-gym crisps
Is a packet of crisps enough after the gym?
Do not assume a crisp packet covers everything you need after demanding or repeated exercise. The British Dietetic Association advises carbohydrate-rich food and fluids when quick recovery is required; consider the packet alongside the rest of your food and drink.
Should I compare calories per bag or per 100g?
Use both figures: per bag describes the labelled portion, while per 100g compares products of different sizes. Seabrook lists 81 kcal per 18g Salt & Vinegar Crunchies bag and 448 kcal per 100g; Walkers lists 96 kcal per 22g Oven Baked Sea Salt packet and 438 kcal per 100g.
Does a packet with fewer calories also have less salt?
Not necessarily. Seabrook lists 0.39g salt per 18g Salt & Vinegar Crunchies bag, while Walkers lists 0.19g per 22g Oven Baked Sea Salt packet. Check the salt line independently of calories and compare per-100g figures when packet sizes differ.
