Commuters looking to reduce fat
If a bar needs to fit into a lunch bag, compare total fat per 100g as well as per bar. Words such as “natural” or “protein” do not tell you whether it meets your fat-content aim.
Who is choosing a bar?
The useful comparison depends on whether fat content is the deciding factor or one requirement among several.
Shoppers balancing several nutrition priorities
If protein or fibre also matters to you, read those values separately from total fat and saturated fat. A bar promoted for one nutrient does not necessarily meet another requirement.
Shoppers checking ingredients and allergens
Vegan, gluten-free and fruit-and-nut descriptions can help narrow a choice. Check the exact pack’s ingredients, allergen information and fat figures before buying.
What should you check?
Start with a like-for-like fat comparison, then look at the bar you would actually eat and any other requirements that matter to you.
| Priority | What to check | Your needs |
|---|---|---|
| Quick label scan | Where shown, use traffic-light labelling to scan fat, saturated fat, sugars and salt. Read the nutrition declaration for the figures behind the colours. | I want to narrow down bars while shopping, without treating a front-of-pack colour as the whole answer. In the Food Standards Agency’s Making Food Better Tracker survey, 49% of respondents said they actively used traffic-light labelling when shopping for food; the survey involved 611 interviews between 16 September and 23 November 2024 and was not specific to snack bars. |
| Fat claim | Check total fat per 100g on the exact bar. The Food and Allergy Information Association gives 3g per 100g as the low-fat claim criterion for solid food; for “reduced fat”, check the stated comparison product. | Reducing total fat is my main reason for choosing a different lunch snack, so I need the figures behind the pack wording. |
| Portion | Compare per 100g to account for different bar sizes, then read the per-bar values for total and saturated fat. Check how many bars you plan to eat. | A small bar may look different when I compare individual portions, so I want to know both how the products compare and what my lunch portion contains. |
| Other requirements | Read protein, fibre and sugars separately from fat. Check ingredients, declared allergens and any “may contain” statement on the exact pack. | I may also want particular ingredients or need to avoid an allergen; neither a protein nor a no-added-sugar claim settles those checks for me. |
Common buying mistakes
-
Reading “no added sugar” or “high protein” as “reduced fat”
Those descriptions concern different aspects of the bar. They do not show whether its total fat meets your aim.
Compare total fat per 100g first, then consider sugar, protein, fibre and ingredients as separate criteria.
-
Comparing only the number per bar
Different bar sizes make per-bar figures a poor basis for comparing fat content between products.
Use the per-100g figures for a like-for-like comparison, then check fat and saturated fat per bar for the portion you would eat.
-
Assuming a familiar range answers an allergen question
Ingredients and precautionary allergen statements matter for anyone who needs to avoid a particular ingredient or possible cross-contact.
Read the ingredients, emphasised allergens and any “may contain” wording on the exact pack, including multipacks.
Brand ranges to recognise
These ranges offer different ways to narrow a snack-bar search, but their brand positioning does not establish that an individual bar is reduced fat.
Graze
Graze includes Oat Boost flapjacks among its portable snacks.
- The range offers oat-based bars to compare.
- Graze’s statements about sugar and saturated-fat changes do not establish the total fat of a particular bar; read its current nutrition panel.
Nature Valley
Nature Valley offers cereal bars, including products positioned around protein and fibre.
- Its product information can help identify bars with stated protein and fibre amounts.
- Check total fat and the exact ingredients separately; protein and fibre descriptions are not reduced-fat claims.
TREK
TREK offers protein bars and flapjacks, including products it describes as vegan.
- Individual product descriptions can help narrow a search by ingredients or dietary preference.
- Check the particular bar’s fat and saturated-fat values rather than inferring them from its protein positioning.
Eat Natural
Eat Natural offers fruit-and-nut and cereal bars, including products it describes as vegan or gluten-free.
- Its range provides ingredient-led options to examine.
- Check total fat and allergens for the individual recipe; fruit-and-nut wording does not mean reduced fat.
nākd.
nākd. describes its fruit-and-nut bars as containing no added sugar.
- The ingredient lists help shoppers distinguish recipes, including those containing peanuts.
- No-added-sugar wording says nothing about total fat; check the exact flavour’s nutrition and allergen information.
Alpen
Alpen’s No Added Sugar muesli is a breakfast cereal, not a portable snack bar.
- Its published per-100g and per-serving nutrition information can be used when considering that muesli as a separate option.
- Do not compare the muesli as though it were an Alpen snack bar for lunch on the go.
Joybuy snack-bar options
These packaged bars are options to examine for lunch on the go. Neither product name establishes a reduced-fat claim, so check the exact pack’s total fat per 100g and per bar before choosing.

Cadbury Brunch Light Orange Cereal Bar, 4pk 104g
For a lunch-on-the-go choice where fat content matters, compare this bar’s current nutrition panel with other bars rather than relying on “Light” in its name. The listed pack contains four bars and weighs 104g.
No image available
Special K Dark Chocolate Snack, 6 x 21.5g
If this is a possible lunch snack, use its per-100g fat figure to compare it with other bars and its per-bar figure to assess your portion. The listed pack contains six 21.5g bars.
Frequently asked questions
What does “low fat” mean on a snack bar?
The Food and Allergy Information Association gives no more than 3g of fat per 100g as the criterion for a low-fat claim on solid food. Check the exact bar’s nutrition declaration; descriptions such as “natural” or “high protein” do not answer the same question.
Does “reduced fat” mean the same thing as “low fat”?
No. “Reduced fat” makes a comparison with another food, while “low fat” refers to a fat-content criterion. Check the product used for the comparison and read the bar’s total fat per 100g.
Should I compare snack bars per bar or per 100g?
Use both: per 100g gives you a consistent basis across different bar sizes, while per bar shows the amount in the portion you plan to eat. Where provided, traffic-light labelling can also help you scan fat, saturated fat, sugars and salt.
Are no-added-sugar fruit-and-nut bars lower in fat?
Not necessarily. “No added sugar” concerns added sugar, not fat; nākd., for example, lists dates and peanuts in its Peanut Delight recipe. Compare total fat and check ingredients on the exact flavour.
What if I need to avoid nuts or peanuts?
Read the exact pack’s ingredients, emphasised allergens and any precautionary “may contain” statement before buying. Do not assume that every flavour or multipack from a familiar brand has the same ingredients or allergen wording.
