Shoppers tracking fat per bar
If fat content guides your choice, compare both the amount in one bar and the amount per 100 g. A reduced-fat comparison and a low-fat claim mean different things.
Who is choosing the bars?
Hosts looking for a chocolate-style treat
A protein bar may fit the treat theme, but protein and sugar claims cannot tell you its fat content or whether it suits everyone taking part.
People sharing food with a group
Check the ingredients and precautionary allergen statements on each flavour’s current pack, particularly when recipients have known allergies or intolerances.
What should you compare?
Start with the claim that matters to you, then compare the nutrition panel on the same serving and per-100 g basis. Check each pack separately before adding bars to a shared hunt.
| Priority | What to check | Your needs |
|---|---|---|
| Fat claim | Check what a reduced-fat claim is compared with, then read total fat per 100 g and per bar. The nutrition-claims annex published by legislation.gov.uk specifies at least a 30% reduction against a similar product for a reduced-nutrient claim; its separate low-fat condition for solid food is no more than 3 g fat per 100 g. | I’m looking specifically for less fat, not assuming that a protein or sugar claim answers the same question. |
| Nutrition and portion | Compare bar weight, saturated fat, energy, protein and sugars using the same per-bar and per-100 g measures. A smaller serving and a lower amount per 100 g answer different questions. | A bar needs to fit the portion I intend to offer as well as the nutritional figures I care about. |
| Sharing | Read the exact flavour’s ingredient list, declared allergens, precautionary statements and sweetener information. Keep the original packaging available for recipients to check. | Other people may eat these bars, so I need to know what is in each flavour before putting it into a shared hunt. |
What can be easy to miss?
-
Reading “high protein” or “low sugar” as “reduced fat”
Those claims describe different nutrients. Tesco Groceries lists 9.1 g fat per 55 g bar for its Barebells Caramel Choco example, alongside 16 g protein.
Compare total and saturated fat on the panel; if reduced fat is your aim, check the stated comparison rather than relying on a protein or sugar claim.
-
Applying one flavour’s comparison to a whole range
Myprotein UK states a flavour-specific reduced-fat comparison for its Lean Layered Protein Bar. A claim for one variant does not establish the figures for another.
Check the comparison wording and nutrition panel for the flavour and pack you are buying.
-
Putting bars into a shared hunt without checking allergens
Bars can have different ingredients and precautionary statements. The Food Standards Agency explains that precautionary allergen labelling communicates possible unintended allergen presence.
Check each current pack, keep its wrapper with the bar and arrange another option for anyone whose requirements it does not meet.
-
Judging the whole bar by a single front-of-pack claim
In its November 2025 audit of 458 snack bars from 10 major UK retailers, Action on Salt & Sugar classified 55% as high in saturated fat and 37% as high in sugars under UK front-of-pack thresholds. Those category findings do not describe every protein bar.
Use the traffic-light label, where present, alongside the exact product’s nutrition panel and serving size.
Which brands are relevant?
Myprotein
Its Lean Layered Protein Bar offers a flavour-specific reduced-fat comparison to examine.
- Myprotein UK states that the Cookie Dough variant contains 42% less fat than its stated typical-protein-bar comparison.
- This is the manufacturer’s comparison, not a low-fat claim for every flavour. Check the current pack’s figures.
PhD
Smart Bar is a protein-and-sugar comparison option, rather than an established reduced-fat option.
- PhD states 20 g protein and less than 2.5 g sugar per Smart Bar.
- Check its fat panel separately if fat is the deciding factor.
Grenade
A chocolate-style protein-bar range to assess flavour by flavour.
- Tesco Groceries states 1.7 g sugar for its listed White Chocolate Cookie bar.
- That sugar figure does not establish a reduced-fat claim.
Barebells
Its Caramel Choco bar illustrates why protein and fat need separate checks.
- Tesco Groceries lists 16 g protein per 55 g Caramel Choco bar.
- The same listing gives 9.1 g fat per bar; check the exact pack before sharing.
Quest
An additional protein-bar range whose individual UK packs need checking.
- Quest Nutrition describes original bars containing up to 21 g protein per bar.
- Its product information discusses sugar alcohols; check the selected flavour’s current UK label rather than applying range-wide figures to it.
Tesco
A retailer whose individual listings can help identify which pack and flavour to check.
- Its Barebells Caramel Choco listing gives per-100 g and per-bar nutrition figures.
- Read the product’s current label before relying on an online listing, particularly for ingredients and allergens.
Joybuy protein bars
These Grenade multipacks are chocolate-style protein bars for shoppers considering Easter treats. Their protein or sugar positioning is not a reduced-fat claim: compare the exact flavour’s fat panel and sharing guidance before choosing.
No image available
Grenade White Chocolate Salted Peanut protein bars, 12 × 60 g
A chocolate-style option for a treat basket, not a substitute for checking fat content. Check the current pack for peanuts, milk and soya, and read its guidance on suitability for children before including it in a hunt.
No image available
Grenade White Oreo protein bars, 12 × 60 g
For a sweet-flavoured bar, compare this variant’s fat per bar and per 100 g rather than using its protein or sugar positioning as a shortcut. Check the pack for milk, soya and wheat, and for guidance on suitability for children.
No image available
Grenade Soft Core Golden Caramel protein bars, 12 × 50 g
The 50 g bar size makes per-bar and per-100 g figures worth reading together. Product information warns against use by children and by pregnant or breastfeeding women; check the current pack’s wording, ingredients and allergens before sharing.
No image available
Grenade Soft Core Double Chocolate protein bars, 12 × 50 g
If chocolate flavour is the attraction, still compare fat for this exact 50 g variant. Product information warns against use by children and by pregnant or breastfeeding women; read the current pack for that guidance and its allergen details.
No image available
Grenade Soft Core Peanut Butter protein bars, 12 × 50 g
Peanut Butter flavour makes an exact-pack allergen check especially important for a shared hunt. Compare its fat figures separately; product information also warns against use by children and by pregnant or breastfeeding women.
Questions about choosing and sharing
Do “reduced fat” and “low fat” mean the same thing?
No. The nutrition-claims annex published by legislation.gov.uk sets a comparative reduction of at least 30% against a similar product for a reduced-nutrient claim; its separate low-fat condition for solid food is no more than 3 g fat per 100 g. Check which claim appears on the exact bar.
Which figures help me compare bars of different sizes?
Read total fat and saturated fat both per 100 g and per bar. The per-100 g figures help compare products on the same basis, while the per-bar figures describe the portion you plan to offer; check energy, protein and sugars on those bases too.
Can a high-protein, low-sugar bar replace a reduced-fat choice?
It can meet a different buying priority, but those claims do not establish reduced fat. For example, Tesco Groceries lists 16 g protein and 9.1 g fat per 55 g Barebells Caramel Choco bar, so check fat separately if that is your deciding measure.
What should I check before sharing bars at an Easter egg hunt?
Check each exact pack’s ingredients, allergen and precautionary statements, sweetener information and any guidance about who should consume it. Keep the wrapper available: the Food Standards Agency explains that precautionary allergen statements signal possible unintended allergen presence.
Do sweeteners matter when choosing a bar?
They are worth checking on the particular pack, especially if someone might eat more than one bar. The Tesco Groceries Barebells Caramel Choco listing identifies sweeteners and carries an excessive-consumption laxative-effect warning; do not assume every flavour has identical ingredients or wording.
