Short-walk snack packers
If you prefer a bar with less fat, compare both the per-100g figure and the amount in the bar you will carry. Neither figure alone tells you how much carbohydrate the portion provides.
Who is choosing a hiking snack?
All-day hikers
For a long hike, carbohydrate and protein may matter more to your choice than minimising fat alone. University College London Hospitals NHS Foundation Trust discusses that combination for long-duration activity, including hiking.
Hikers checking dietary requirements
Check the exact flavour and pack for ingredients and allergen warnings. Tesco Groceries lists nuts or soya in the ingredients or warnings for some of the fruit-and-nut and protein bars discussed here; a vegan or gluten-free description does not replace that check.
What should you compare?
Start with the length of the walk and the portion you expect to eat, then compare nutrition figures on the same basis before checking the exact pack’s ingredients.
| Priority | What to check | Your needs |
|---|---|---|
| Fat content | Compare total fat per 100g across bars, then fat per bar to see what your chosen portion contains. Do not substitute a lower-sugar message for either figure. | I would prefer a bar with less fat for a shorter walk, but still want to know what is in the whole bar. |
| Carbohydrate | Read carbohydrate per bar and the stated serving size. For an all-day hike, consider protein alongside carbohydrate: University College London Hospitals NHS Foundation Trust discusses this combination for long-duration activity. | On a longer walk, I want to compare the food I am actually packing, rather than choose by fat content alone. |
| Portion and energy | Check the bar weight and energy per bar. The Tesco Groceries listings for nākd. Cocoa Delight, TREK Original Oat and Graze Cocoa Vanilla Oat Boost use 35g, 50g and 30g portions respectively. | A smaller bar might suit my snack plans, but I do not want to mistake a smaller portion for a lower-fat recipe. |
| Ingredients and allergens | Read the current ingredients and allergen statement for the exact flavour, including any may-contain warnings. Check dietary descriptions against that same pack. | If I avoid particular ingredients, the bar needs to fit those requirements regardless of its fat figure. |
Common selection mistakes
-
Reading “lower sugar” as “lower fat”
A sugar comparison does not establish total fat content. Tesco Groceries lists Graze Cocoa Vanilla Oat Boost at 22g fat per 100g, regardless of Graze’s separate lower-sugar messaging.
Use the nutrition panel’s total-fat figures per 100g and per bar when comparing fat.
-
Choosing for an all-day hike by fat alone
University College London Hospitals NHS Foundation Trust discusses a mixture of carbohydrate and protein for long-duration activity such as an all-day hike. A fat figure cannot show you how much of either a bar contains.
Compare carbohydrate and protein per bar as well as fat when planning food for a longer route.
-
Comparing differently sized bars only per serving
The Tesco Groceries examples include 30g, 35g and 50g bars. A per-bar fat figure reflects both the recipe and the size of the portion.
Use fat per 100g for a like-for-like comparison, then check the values for the bar you would eat.
-
Relying on a dietary description instead of the allergen statement
A bar described as vegan or gluten-free can still contain other allergens or carry may-contain warnings. The Tesco Groceries listings for nākd. Cocoa Delight and TREK Original Oat illustrate why the exact product matters.
Read the ingredients and allergen statement on the current flavour and pack before putting it in your hiking bag.
Brand and product-line references
These examples concern particular products or lines, not every bar from each brand; compare the current label of the one you plan to buy.
nākd.
Fruit-and-nut bars, including the Cocoa Delight example listed by Tesco Groceries.
- Tesco Groceries lists Cocoa Delight at 14g fat per 100g and 4.9g per 35g bar, with 19g carbohydrate per bar.
- That product contains cashews and carries may-contain warnings for soya, peanuts and other nuts. Its fat figures alone do not establish a “reduced fat” claim.
TREK
Protein flapjacks, including the Original Oat product listed by Tesco Groceries.
- The listed Original Oat 50g bar has 23g carbohydrate and 10g protein.
- The same bar has 9.4g fat, or 19g per 100g. It contains soya and carries may-contain warnings for peanuts, nuts and milk.
Graze
An oat-flapjack range that includes Cocoa Vanilla Oat Boost.
- Tesco Groceries lists the Cocoa Vanilla Oat Boost portion as a 30g bar, which makes its per-bar figures relevant when planning a small snack.
- That listing gives 6.5g fat per bar and 22g per 100g. Graze’s lower-sugar messaging should not be read as a claim about this bar’s total fat.
Nature Valley
Its UK range includes Crunchy oat bars and other snack-bar lines.
- Nature Valley UK identifies Oats & Honey as a Crunchy oat bar; Tesco Groceries lists a 42g pack at 196kcal.
- Check the exact product’s current fat figures before comparing it with bars selected for lower fat.
Eat Natural
Fruit-and-nut snack bars, including a Red Berries Soft Fruit Bar listed by Tesco Groceries.
- Tesco Groceries describes that 25g bar as vegan and gluten-free and lists it at 87kcal per bar.
- Check its current fat values and allergen statement before treating it as a lower-fat option for your hike.
Alpen
Alpen’s cited UK product pages describe a wholegrain muesli range.
- Muesli-range information cannot establish the nutrition or suitability of an Alpen snack bar. Compare an exact bar’s pack if you are considering one.
Joybuy snack-bar options

Questions about hiking snack bars
Is a lower-fat bar automatically the right hiking snack?
No. Fat is one part of the comparison: check carbohydrate, protein and the portion you will eat. University College London Hospitals NHS Foundation Trust discusses carbohydrate together with protein for long-duration activity such as an all-day hike.
What does “reduced fat” tell me about a bar?
Those words do not tell you how much fat is in the bar you will eat or whether its other nutrition figures fit your hike. Compare total fat per 100g and per serving on the current pack, alongside its carbohydrate and portion size.
Which nutrition figures help when bars are different sizes?
Use fat per 100g to compare differently sized bars on the same basis, then check fat, carbohydrate and energy for the bar you would actually carry. For a longer hike, protein per bar is another useful comparison; the serving sizes in the Tesco Groceries examples range from 30g to 50g.
Does vegan or gluten-free mean a bar is suitable for someone avoiding nuts?
No. Check the exact pack’s ingredients and allergen warnings. Tesco Groceries lists cashews and may-contain warnings for other nuts and peanuts on nākd. Cocoa Delight, while its TREK Original Oat listing carries a may-contain warning for peanuts and nuts.
