Gym-goers looking for crunch and protein
If you want a maize snack after training, the protein per pack helps you distinguish a small contribution from a snack chosen primarily for protein.
Who is choosing a post-gym maize snack?
Vegan or gluten-free snack shoppers
A corn-and-legume cake may suit you better than a cheese-flavoured maize puff. Check the exact product label for ingredients, gluten information and possible cross-contact.
Fans of familiar multipack crisps
You can choose Wotsits or Monster Munch for their familiar flavour and crunch, then decide separately what protein-containing food to have after a longer training session.
What should you check before buying?
Start with the portion you plan to eat, then consider what else you will have after training.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per portion | Compare protein per pack or serving before comparing per 100g figures. Walkers lists 1.2g per pack for Wotsits Cheese and Monster Munch Pickled Onion; Myprotein lists 3.8g per Protein Popcorn serving. | I want to know what the amount I actually eat contributes, rather than judging a snack by its name. |
| High-protein claim | In Great Britain, the high-protein claim rule requires at least 20% of a food’s energy to come from protein. Check the nutrition panel; grams of protein alone do not establish whether that threshold is met. The rule appears in Regulation (EC) No 1924/2006, with the Great Britain framework described in GOV.UK guidance applying from 1 January 2021. | If I am shopping specifically for a high-protein food, I need to distinguish that claim from a product that simply contains added protein. |
| Food after training | Consider the duration of the session and your next meal. The British Heart Foundation says extra protein after exercise lasting more than an hour can be useful alongside carbohydrate. | After a longer session, I may want a meal or a more substantial snack rather than expecting a small bag of crisps to cover everything. |
| Ingredients and allergens | Read the label for the exact flavour and pack. Walkers identifies milk in Wotsits Cheese and milk, wheat and soya in Monster Munch Roast Beef; Myprotein lists whey protein isolate in Protein Popcorn. | I need to check whether a particular flavour fits the ingredients I avoid, not assume every maize snack has the same recipe. |
| Pack format | Check whether the pack is a single portion, a multipack or a sharing bag, and use its stated size when reading the nutrition panel. | A bag I can take with me matters if I am eating on the way home; a sharing bag means deciding my portion separately. |
What is easy to overlook?

Counting any protein as a substantial serving
Walkers lists 1.0g protein per 12g Wotsits Cheese Toastie pack and 1.2g per pack for Wotsits Cheese and Monster Munch Pickled Onion. Those pack amounts matter more to this decision than the presence of protein on a nutrition panel.
Compare the pack amount with what else you plan to eat. If you choose crisps for flavour, have a separate protein-containing food or a meal containing protein and carbohydrate when that suits your training.

Taking “protein popcorn” to mean “high protein”
Added protein does not, by itself, establish that a food meets Great Britain’s high-protein claim threshold of 20% of energy from protein, set out in Regulation (EC) No 1924/2006 and described in GOV.UK guidance.
Read the nutrition panel and the protein amount for the serving you intend to eat.
-
Assuming flavours share the same allergens
Walkers lists different ingredient and allergen information across its maize snacks: Wotsits Cheese contains milk, while Monster Munch Roast Beef lists milk, wheat and soya.
Check the physical pack of the exact flavour each time, particularly if you have an allergy, intolerance or coeliac disease.
-
Expecting a crisp snack to cover a longer workout
After exercise lasting more than an hour, the British Heart Foundation says extra protein alongside carbohydrate can be useful. A small crisp pack need not be your only food after that session.
Consider a meal or a more substantial snack containing carbohydrate and protein, as well as fluids, rather than choosing solely by crunch.
Which brands illustrate the differences?
These examples show why the recipe and serving size matter; a brand name alone does not tell you how much protein is in your pack.
Verival
Verival Green Protein Corn Cakes combine corn with legumes and pea protein, rather than using the recipe of a conventional puffed maize crisp.
- Verival lists 18.4g protein per 100g and describes the cakes as vegan and gluten-free.
- The per-100g figure is not a per-piece amount. Verival also warns that the product may contain traces of soya.
Myprotein
Protein Popcorn is a maize-kernel snack with added whey protein isolate.
- Myprotein lists 3.8g protein per serving.
- Whey is milk-derived. Check the full allergen information on the pack if milk or soya matters to you.
Wotsits
Wotsits Cheese is a familiar maize-based crisp; Wotsits Cheese Toastie has chickpea flour as its first ingredient.
- Walkers lists 1.2g protein per 22.5g Wotsits Cheese pack and 1.0g per 12g Cheese Toastie pack.
- Check the exact flavour for allergens. Neither pack amount should be mistaken for a substantial protein serving.
Monster Munch
Monster Munch Pickled Onion is a maize-based crisp to consider for flavour and crunch rather than its protein amount.
- Walkers lists 1.2g protein per 20g Pickled Onion pack.
- Recipes differ by flavour: Walkers lists milk, wheat and soya for Monster Munch Roast Beef.

Common questions
Is a standard bag of Wotsits or Monster Munch a substantial post-gym protein snack?
No: Walkers lists 1.2g protein per 22.5g Wotsits Cheese pack and 1.2g per 20g Monster Munch Pickled Onion pack. If protein is the reason for your post-gym snack, consider what protein-containing food you will have alongside it or at your next meal.
What does “high protein” mean on a food label in Great Britain?
The high-protein claim rule requires at least 20% of the food’s energy to come from protein under Regulation (EC) No 1924/2006; GOV.UK describes the Great Britain framework applying from 1 January 2021. A product name or the presence of added protein does not establish that it meets the threshold.
Do I need a protein snack immediately after every gym session?
Not necessarily. The British Heart Foundation places more emphasis on protein-containing meals across the day after exercise lasting under an hour; for sessions lasting longer than an hour, it says extra protein alongside carbohydrate can be useful.
Which allergens should I check in maize snacks?
Check the exact flavour’s pack. Walkers lists milk in Wotsits Cheese and milk, wheat and soya in Monster Munch Roast Beef; Myprotein’s Protein Popcorn contains milk-derived whey protein isolate. Verival describes its Green Protein Corn Cakes as vegan and gluten-free but warns of possible soya traces.
