Choose a bar marketed as lower in fat only if its fat figures per 100g and per bar suit your picnic lunch; a comparison with another bar does not make it a low-fat food. The low-fat condition for solid foods published by legislation.gov.uk is no more than 3g fat per 100g, while Myprotein states that its Lean Layered Cookie Dough bar contains 8.1g per 100g. Check the current wrapper for allergens and storage instructions before packing or sharing a bar.
If fat content is your deciding factor, compare bars per 100g before checking how much fat is in the bar you would actually eat. A claim about having less fat than another bar answers a different question from whether a food qualifies as low fat.
If you want a bar as part of lunch, check protein per bar alongside fat, saturated fat and sugars. A higher protein figure or a low-sugar description does not, by itself, tell you the fat content.
Check each flavour’s current wrapper before offering it to someone else. The cited bars illustrate why ingredient lists, allergen statements and any sweetener warnings matter for a shared picnic.
Start with the per-100g label to compare bars of different sizes, then use the per-bar figures and the wrapper’s practical instructions to decide what to pack.
| Priority | What to check | Your needs |
|---|---|---|
| Fat content | Compare total fat per 100g, then fat and saturated fat per bar. The low-fat condition for solid foods published by legislation.gov.uk is no more than 3g fat per 100g. | I want to tell whether a bar has less fat than another bar or actually meets the low-fat condition. |
| Protein and sugars | Read protein and sugars per bar alongside fat and saturated fat. Compare per-100g values when bar sizes differ. | Protein matters to me, but I do not want a protein or low-sugar claim to stand in for the rest of the nutrition label. |
| Ingredients and warnings | Read the exact flavour’s ingredient list, declared allergens, precautionary statements and any sweetener or polyol warning. | If I am sharing bars, I need to check whether each one is suitable for the person who will eat it. |
| Picnic storage | Follow the bar’s storage instructions. The Food Standards Agency says foods normally kept in the fridge at home also need to be kept cool at a picnic. | I can pack the bar according to its label while keeping refrigerated parts of lunch cool separately. |
Myprotein describes its Lean Layered Cookie Dough bar as lower in fat than its stated typical-bar comparison, but lists 8.1g fat per 100g. That exceeds the 3g-per-100g low-fat condition for solid foods published by legislation.gov.uk.
Use fat per 100g to assess the claim, then check fat and saturated fat per bar for the portion you plan to pack.
The cited Grenade Caramel Chaos and PhD Cookies & Cream listings each give 22g protein per bar, alongside 7.6g and 8.6g fat per bar respectively, according to their Joybuy product information.
Decide what role the bar has in lunch, and compare its protein, fat and saturated fat figures on the same serving basis.
Allergen statements and sweetener warnings can affect whether a bar is suitable to share. Tesco’s listing for Barebells Cinnamon Bun, for example, includes milk and precautionary allergen information.
Read the current wrapper for the exact flavour, including its ingredients and “may contain” statements, before packing it for someone else.
A bar’s storage directions do not determine how to pack foods that normally need refrigeration.
Follow each item’s instructions. The Food Standards Agency advises keeping foods normally refrigerated at home cool at a picnic; Food Standards Scotland describes using a cool bag or box with ice or frozen gel packs.
These examples illustrate different label checks; they do not describe every bar made by each brand.
Its Lean Layered Cookie Dough bar is a useful example of a relative fat comparison rather than a low-fat qualification.
The cited Carb Killa Caramel Chaos listing shows why a protein figure needs to be read alongside fat.
The cited Smart Protein Nutrition Bar Cookies & Cream listing provides another per-bar comparison for a picnic snack.
The cited Cinnamon Bun Soft Protein Bar is an example where the per-bar nutrition and allergen statement both matter.
Tesco is a retailer reference for the cited Barebells product, not the manufacturer of that bar.
These Grenade packs are options to consider if you want a protein bar for a picnic. Compare the current fat figures on their wrappers before treating any of them as a reduced-fat choice.

This is a 12 × 50g Peanut Butter pack. For a shared picnic, check the exact wrapper’s allergen statement as well as its fat and saturated fat figures.

This pack contains 12 × 60g bars. Compare fat per 100g with the other packs, then read the per-bar figures and allergen statement if you plan to include one in a picnic lunch.
Not necessarily. The low-fat condition for solid foods published by legislation.gov.uk is no more than 3g fat per 100g. Myprotein states that its Lean Layered Cookie Dough bar has less fat than its stated typical-bar comparison, but its listed 8.1g per 100g is above that low-fat condition.
Use both: per 100g makes different-sized bars easier to compare, while per-bar figures describe the portion you would eat. The NHS explains that nutrition information is given per 100g and sometimes per portion; check the current wrapper for fat, saturated fat, protein, sugars and other details relevant to your choice.
Follow that bar’s storage instructions rather than assuming every bar has the same requirements. Keep the rest of the lunch in mind too: the Food Standards Agency says foods normally kept in the fridge at home also need to be kept cool at a picnic.
Read the current wrapper for the exact flavour, including its ingredients, declared allergens, “may contain” statements and any sweetener warning. Tesco’s listing for Barebells Cinnamon Bun, for example, names milk and gives precautionary information for gluten-containing cereals, peanuts, nuts and sesame.
