People following a strict carbohydrate limit
Check carbohydrate per pack before deciding whether a familiar maize snack fits your own daily plan. A small pack or a baked recipe is not, by itself, a low-carbohydrate choice.
Who is choosing these snacks?
Calorie-conscious crisp snack buyers
An individual pack makes the portion easier to identify. Compare its calories and carbohydrate as two separate figures, particularly if you are reducing carbohydrate without following a strict ketogenic diet.
Buyers checking allergens
Maize-based snacks can have different milk, soya and wheat-related declarations. Read the ingredients and any precautionary allergen statement on the exact pack as well as its nutrition label.
What should you check before buying?
Start with the carbohydrate figure for the portion you expect to eat, then check calories and ingredients against your separate requirements.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate | Read carbohydrate per inner pack or intended serving. Walkers UK lists 12g per 20g Monster Munch Pickled Onion pack; Tesco Groceries lists 12g per 20g Frazzles pack. Compare the figure with the limit you use. | I need to know how much of my daily carbohydrate allowance a snack would use before choosing it for a strict plan. |
| Calories | Compare energy and carbohydrate on the same portion basis. Walkers UK lists 98 kcal and 12g carbohydrate for a 20g Monster Munch Pickled Onion pack; Tesco Groceries lists 97 kcal and 12g for 20g of Frazzles. | A small pack may suit my calorie plans, but I do not want its calorie figure to stand in for a carbohydrate check. |
| Portion size | Check whether the label describes an inner pack, a serving from a larger bag or 100g. Tesco Groceries lists 124 kcal and 15.9g carbohydrate per 25g portion of Tesco Free From Onion Maize Snack Rings. | If I am eating from a larger bag, I need the figures for the amount I will actually serve, not just the amount shown prominently on the label. |
| Ingredients and allergens | Read the exact recipe, declared allergens and any “may contain” wording. Tesco labels its Free From Onion Maize Snack Rings gluten-free, wheat-free and milk-free, but lists 15.9g carbohydrate per 25g portion. | I need to check allergen suitability and carbohydrate separately; a free-from label answers only the requirements it names. |
Common buying mistakes
-
Assuming fewer than 100 kcal means keto-friendly
A 20g pack of Monster Munch Pickled Onion has 98 kcal and 12g carbohydrate according to Walkers UK. Tesco Groceries lists 97 kcal and 12g carbohydrate for a 20g Frazzles pack.
Check carbohydrate for the pack you will eat first if you have a strict limit; use calories as a separate measure.
-
Reading the serving figure as the whole bag
Tesco Groceries gives its Free From Onion Maize Snack Rings figures for a 25g portion. Eating a different amount changes the amount of carbohydrate and energy consumed.
Check the serving size and compare it with the amount you plan to put in a bowl or eat from the bag.
-
Using maize or free-from wording as an allergen shortcut
Recipes differ, and a free-from declaration does not address every allergen or establish carbohydrate suitability. The Food Standards Agency explains that precautionary allergen labelling communicates possible unintended allergen presence.
Read the current pack’s ingredients, declared allergens and precautionary statement for your specific requirements.
Brand and range references
These examples refer to the named products and portions, not every recipe or pack size sold under each brand.
Wotsits
A baked maize-snack reference for comparing different pack sizes.
- Joybuy UK lists 82 kcal per 16.5g Really Cheesy pack; Walkers UK lists 123 kcal and 12.6g carbohydrate per 22.5g Wotsits Cheese pack.
- Do not apply one pack’s nutrition figures to another size or recipe. Walkers UK declares milk for Wotsits Cheese.
Monster Munch
Pickled Onion provides an individually labelled maize-snack portion for comparison.
- Walkers UK lists 98 kcal and 12g carbohydrate per 20g Pickled Onion pack.
- That carbohydrate amount needs checking against a strict daily limit; read the current pack’s allergen declaration too.
Frazzles
A bacon-flavour corn snack sold in 20g multipack portions.
- Tesco Groceries lists 97 kcal and 12g carbohydrate per 20g pack.
- The listed recipe contains milk and soya; check its current precautionary allergen information.
Tesco
Its Free From and standard onion rings illustrate why ingredient requirements and carbohydrate need separate checks.
- Tesco labels Free From Onion Maize Snack Rings gluten-free, wheat-free and milk-free.
- Tesco Groceries lists 15.9g carbohydrate per 25g Free From portion. Its standard Onion Rings contain durum wheat semolina and list 15.6g available carbohydrate per 25g portion.
Quavers
Cheese Quavers are a small-pack comparison, but their listed ingredients begin with potato starch rather than maize.
- Walkers UK lists 86 kcal and 9.9g carbohydrate per 16g Cheese pack.
- This is not a maize-based example. Check the current ingredient and allergen declaration before buying.
Joybuy snack options
These options are non-maize snacks: konjac products and a protein bar. They will not offer the same eating experience as maize puffs. Compare the current label’s carbohydrate and calories for the portion you intend to eat before choosing one for a carbohydrate-conscious plan.

Wei Long Spicy Vegetarian Tripe-Style Konjac Crisps, 360g (20 × 18g)
The 18g packs provide a defined portion, but this konjac snack is not a maize puff. Check carbohydrate and calories per pack, along with the current allergen label.
No image available
Wei Long Hot and Sour Vegetarian Tripe-Style Konjac Snack, 360g
The box is described as containing approximately 20 small packs. This is a konjac snack rather than a maize snack; check the size and nutrition of an inner pack, and read its allergen declaration.
No image available
Yan Jin Pu Zi MOWON Sesame Paste Konjac Snack, 20 × 18g
The stated 18g pack size gives you a portion to compare with the nutrition label. It is not a maize snack; check the current ingredient and allergen information, particularly if sesame, peanuts or soya matter to you.
No image available
Grenade Soft Core Peanut Butter Protein Bar, 12 × 50g
A 50g protein bar is a different choice from a crunchy maize snack. Check its current carbohydrate, calorie, polyol and allergen information per bar rather than assuming that a protein-bar label means it fits your plan.
No image available
Be&Cheery Spicy Hot Pot Crispy Konjac Snack, 120g
For this 120g konjac snack, decide on a serving before comparing its carbohydrate and calorie figures. It is not a maize snack; read the current ingredient and allergen label as well.
Frequently asked questions
Are low-calorie maize snacks automatically keto-friendly?
No. Calories measure energy, while the carbohydrate in the portion you eat is a separate consideration for a carbohydrate limit. Walkers UK lists 98 kcal and 12g carbohydrate for a 20g Monster Munch Pickled Onion pack; compare both figures with your own plan.
Does “baked not fried” mean a maize snack is low in carbohydrate?
No. It describes how the snack is made, not its carbohydrate content. Walkers UK lists 12g carbohydrate per 20g pack of Monster Munch Pickled Onion, so read the nutrition figure for the exact product and portion.
Should I check allergens when buying a familiar snack again?
Yes. Read the current pack’s ingredients, declared allergens and precautionary statement rather than relying on a previous purchase. The Food Standards Agency explains that “may contain” wording communicates possible unintended allergen presence.
What if my ketogenic diet is medically supervised?
Discuss substantial carbohydrate changes with your clinical or dietetic team before changing a medically supervised plan. A snack’s calorie figure or a general description of a ketogenic diet cannot establish whether that snack fits your individual requirements.
