If you specifically want reduced fat, compare total fat per 100g and check what any reduced-fat claim is compared with; a small portion, lower-sugar wording or added protein answers a different question. For solid foods in Great Britain, the low-fat claim threshold set out in legislation published by legislation.gov.uk is no more than 3g fat per 100g. That is a different claim from reduced fat: Alpen Light Chocolate & Fudge lists 6.5g per 100g, so its name and small serving do not establish either claim.
If fat content is the deciding factor, use the per-100g figure to compare bars of different sizes. The low-fat claim threshold for solid foods in Great Britain is no more than 3g fat per 100g, as set out in legislation published by legislation.gov.uk; a reduced-fat claim requires a separate comparison.
A per-bar declaration tells you about the portion you would eat between breakfast and lunch. Compare it alongside the per-100g figure so that a smaller bar is not mistaken for a lower-fat formulation.
Check the exact flavour and pack: the listed nākd. Blueberry Muffin bar contains cashews and almonds, while the listed Nature Valley Protein Peanut & Chocolate bar contains peanuts, soya and milk, according to their Joybuy product information.
Start with the fat declaration and the wording of any claim, then check what the portion and ingredients mean for the snack you plan to eat.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Compare total fat per 100g. Check the comparator stated for any reduced-fat claim; do not treat it as interchangeable with a low-fat claim. Legislation published by legislation.gov.uk sets the low-fat claim threshold for solid foods at no more than 3g fat per 100g in Great Britain. | Fat content matters most to me, so I want to compare bars on the same basis rather than rely on words such as “Light”. |
| Portion | Read the serving weight and the energy, fat and other nutrition values per bar after comparing per-100g values. Nature Valley UK explains that these figures serve different comparison and portion-checking purposes. | For a mid-morning break, I want to know what the bar I would actually eat contains. |
| Other claims | Read sugar and protein information separately from total fat. Nature Valley Oaty & Crispy Honey lists 8.0g fat per 100g despite its lower-sugar statement; the Joybuy listing for Nature Valley Protein Peanut & Chocolate lists 28.3g fat per 100g. | A lower-sugar or protein-focused bar may interest me, but I do not want to mistake that feature for lower total fat. |
| Ingredients | Check the ingredient list, declared allergens and any “may contain” statement for the exact variant. | If I need to avoid particular ingredients, the label for the bar I am buying matters more than the range name. |
These descriptions refer to different attributes. For example, Weetabix Cereals lists 6.5g fat per 100g for Alpen Light Chocolate & Fudge, above the low-fat claim threshold for solid foods in Great Britain.
Check total fat per 100g and the stated basis of any reduced-fat claim before deciding whether the bar meets your requirement.
Different serving weights make per-bar figures unsuitable for a like-for-like comparison of fat concentration.
Compare fat per 100g first, then use the per-bar declaration to assess the portion you intend to eat.
The Joybuy listings identify cashews and almonds in nākd. Blueberry Muffin and peanuts, soya and milk in Nature Valley Protein Peanut & Chocolate.
Read the current ingredient, allergen and precautionary statements for the exact product before buying or eating it.
A brand’s range can contain bars with different ingredients and nutrition values, so use these examples to identify which specific labels to compare.
Alpen Light Chocolate & Fudge is a portioned cereal-bar example, not an example that meets the low-fat claim threshold.
Its oat and protein bars answer different preferences; neither name establishes a low-fat choice.
Graze discusses sugar and saturated-fat changes to its Oat Boost flapjacks.
nākd. describes its fruit-and-nut range as vegan and free from added sugar, gluten and dairy.
Eat Natural lists fruit-and-nut, high-fibre, vegan and protein bars among its UK product routes.
This fruit-based option may suit a mid-morning break, but it is not a cereal or oat bar. Check its own nutrition panel if a reduced-fat snack bar is your specific requirement.

A fruit-based alternative to a cereal bar for a mid-morning snack. The listed pack is 100g; compare its current total-fat declaration per 100g and per portion, and check the ingredients and allergens before choosing it.
No. For solid foods in Great Britain, the low-fat claim threshold set out in legislation published by legislation.gov.uk is no more than 3g fat per 100g. Weetabix Cereals lists 6.5g fat per 100g for Alpen Light Chocolate & Fudge, so its name and 65 kcal serving do not establish a low-fat claim.
