Snackers balancing fat and protein
If you want crisps occasionally while paying attention to protein, decide whether your priority is a lower-fat crisp or more protein in the crisp serving. Neither choice needs to be your main protein food.
Who is this choice for?
Portion-conscious snack buyers
Individual bags make the labelled portion straightforward to identify. Walkers lists 96kcal, 2.8g fat and 1.3g protein for each 22g Oven Baked Cheese & Onion pack.
Shoppers checking flavour-specific allergens
Check the exact flavour as well as its nutrition panel. The researched Walkers Cheese & Onion and Tyrrells Sour Cream & Onion products contain milk and carry additional may-contain statements.
What should you check?
Start with the fat and protein figures for the amount you expect to eat, then check the rest of the label for that exact flavour.
| Priority | What to check | Your needs |
|---|---|---|
| Fat comparison | Read what the reduced-fat claim compares with. Compare fat per 100g as well as per pack: Walkers lists 13g per 100g for Oven Baked Cheese & Onion, while Tyrrells lists 19g per 100g for Lentil Sour Cream & Onion. | I want a crisp with a stated fat reduction, rather than assuming that baked, lentil or hand-cooked means lower fat. |
| Protein per portion | Check protein in the labelled serving and how much you expect to eat. Walkers lists 1.3g per 22g pack; Tyrrells lists 4.2g per 30g serving. The portions are different sizes. | If the snack needs to contribute meaningfully to my protein intake, I’ll consider a protein-rich food alongside or instead of crisps. |
| Portion and full label | Check pack size, calories and salt per serving, then use per-100g values for a like-for-like comparison. Walkers lists 96kcal and 0.20g salt per 22g pack; Tyrrells lists 139kcal and 0.23g salt per 30g serving. | A smaller bag helps me see how much I’m eating; a sharing bag calls for a closer look at the portion I’ll serve. |
| Ingredients and allergens | Read the ingredient list and allergen declaration on the exact flavour and pack. The researched Walkers and Tyrrells flavours both contain milk and have may-contain statements. | I need to check suitability for my dietary requirements rather than relying on words such as “lentil” or “baked”. |
Common buying mistakes
-
Assuming reduced fat means high protein
A fat-reduction claim compares a product with another type of crisp; it does not describe how much protein a serving contributes. Walkers Oven Baked Cheese & Onion contains 1.3g protein per 22g pack, and Tyrrells Lentil Sour Cream & Onion contains 4.2g per 30g serving.
Read the protein figure for the portion you plan to eat. If protein is the point of the snack, consider a protein-rich food alongside or instead of the crisps.
-
Comparing only the front-of-pack percentage
Walkers’ 50% less-fat statement and Tyrrells’ 30% less-fat statement refer to their respective comparisons with regular or standard potato crisps. Those percentages do not tell you the amount of fat or protein in differently sized servings.
Compare the declared fat and protein per 100g, then check the figures for the portion you will actually eat.
-
Assuming a product type settles allergen questions
The researched Tyrrells lentil flavour contains milk and may contain soya and gluten. The researched Walkers baked flavour also contains milk and carries several may-contain statements.
Read the current ingredient and allergen declaration for the exact flavour before buying or eating it.
-
Choosing standard crisps for a slightly higher protein figure
The manufacturer declarations for the researched KETTLE Chips, Seabrook, McCoy’s and REAL products list 5.6g–6.6g protein per 100g, alongside 29.5g–32g fat per 100g. A protein figure alone therefore does not establish that one of these products fits a reduced-fat purchase.
When both considerations matter, compare fat and protein on the same per-100g basis, then decide whether a separate protein food would better serve the snack’s purpose.
Relevant brand examples
These figures describe the named products and flavours, not every crisp made by each brand.
Walkers
Oven Baked Cheese & Onion is a potato-crisp option sold in 22g packs.
- Walkers states 50% less fat than regular potato crisps and declares 2.8g fat per 22g pack.
- Each pack contains 1.3g protein. This flavour contains milk; check its full may-contain statement if allergens matter to you.
Tyrrells
Lentil Crisps Sour Cream & Onion offers a different crisp format with a stated fat comparison.
- Tyrrells states its lentil crisps have 30% less fat than standard potato crisps on average; this flavour lists 4.2g protein per 30g serving.
- The same serving lists 5.7g fat. This flavour contains milk and may contain soya and gluten.
KETTLE Chips
Lightly Salted provides a standard potato-crisp comparison when reading per-100g nutrition.
- KETTLE Chips lists 6.5g protein per 100g and describes this product as suitable for vegans and vegetarians.
- The manufacturer also lists 29.5g fat per 100g; do not treat this named product as a reduced-fat choice on the strength of its protein figure.
Seabrook
Sea Salted is a crinkle-cut potato crisp to compare with reduced-fat products, rather than an interchangeable alternative.
- Seabrook describes this flavour as gluten-free and suitable for vegans and vegetarians.
- Its declaration lists 30.4g fat and 5.9g protein per 100g.
McCoy’s
Original Salted is a ridge-cut standard crisp for checking the fat–protein trade-off.
- McCoy’s lists 6.6g protein per 100g for this flavour.
- The same declaration lists 32g fat per 100g, so the protein figure should not be read as a reduced-fat claim.
REAL Hand Cooked Crisps
Sea Salt is another standard crisp to assess using its declared nutrition, not its cooking description alone.
- REAL describes this flavour as suitable for vegans and vegetarians.
- Its declaration lists 30.0g fat and 5.6g protein per 100g.

Walkers Oven Baked Cheese & Onion 6 × 22g
For a pre-portioned potato crisp when reducing fat is the priority: Walkers states 50% less fat than regular potato crisps. Its declaration lists 2.8g fat and 1.3g protein per 22g pack. This flavour contains milk; check the pack’s may-contain statement.

Eat Real Sea Salt Lentil Chips 95g
If you want a lentil-chip format, compare its declared fat and protein per 100g with other crisps rather than assuming the ingredient determines either figure. The 95g pack also warrants a check of your intended serving size.
No image available
PopChips Sour Cream & Onion 85g
For another crisp-style option, read the 85g pack’s fat and protein declarations before comparing it with a product carrying a stated reduced-fat claim. Check the exact flavour’s ingredients and the portion you intend to serve.
Frequently asked questions
Does reduced fat mean a crisp provides plenty of protein?
No. A reduced-fat comparison says nothing by itself about protein in a serving. Walkers declares 1.3g protein per 22g Oven Baked Cheese & Onion pack, while Tyrrells declares 4.2g per 30g Lentil Sour Cream & Onion serving. Check those figures against what you want the snack to contribute.
Which of the two researched reduced-fat crisps lists less fat?
Walkers Oven Baked Cheese & Onion lists 2.8g fat per 22g pack and 13g per 100g; Tyrrells Lentil Sour Cream & Onion lists 5.7g per 30g serving and 19g per 100g. The serving sizes differ, so use the per-100g figures for a like-for-like comparison and the serving figures for the amount you expect to eat.
What could I have with crisps if I want more protein in the snack?
Consider a protein-rich food alongside the crisps, or choose that food instead if protein is the snack’s main purpose. Cambridge University Hospitals NHS Foundation Trust identifies foods including fish, eggs, dairy, pulses, tofu and Quorn as protein-rich options in its high-protein diet guidance.
Should I check salt and calories on reduced-fat crisps?
Yes. A fat-reduction statement does not specify either figure. Walkers lists 96kcal and 0.20g salt per 22g Oven Baked Cheese & Onion pack; Tyrrells lists 139kcal and 0.23g salt per 30g Lentil Sour Cream & Onion serving.
Can I rely on “lentil” or “baked” wording when checking allergens?
No. The researched Walkers Oven Baked Cheese & Onion and Tyrrells Lentil Sour Cream & Onion flavours both contain milk and have additional may-contain statements. Read the ingredient and allergen declaration on the exact pack, particularly if you need to avoid gluten or soya.
