Car boot sellers offering sealed snacks
Choose packs that can be displayed and handed over without preparation. Keep each manufacturer label with its bar so customers can read the ingredients, allergens, date marking and storage instructions.
Who is choosing the bars?
The same bar has to work as a labelled item at the stall and as a snack that meets the buyer’s own priorities.
Shoppers comparing fat content
Use the fat figure per 100g to compare flavours and brands on the same basis. Myprotein lists 8.1g or 8.6g per 100g for two Lean Layered flavours; the specified Grenade, PhD and Barebells examples list 13g, 14g and 16g respectively, according to Tesco Groceries, PhD and Barebells UK.
Buyers checking allergens and sweeteners
Read the full label for every flavour rather than assuming bars from one range have identical ingredients. The cited product pages include milk and soy declarations, precautionary allergen statements and, for some bars, information about polyols or excessive consumption.
What should you check before buying?
Start with the fat figure if that drives the choice, then check what one bar provides and whether its packaging and label will work at the stall.
| Priority | What to check | Your needs |
|---|---|---|
| Fat content | Compare fat per 100g for the exact flavour. Myprotein lists 8.1g for Lean Layered Cookie Dough and 8.6g for White Chocolate and Raspberry; its comparison with a typical protein bar was verified in October 2022 and is manufacturer-provided. Check sugar separately. | I’m looking for a bar with less fat than the alternatives I’m considering, not just one described as low in sugar. |
| Protein per bar | Compare the amount in one bar alongside its serving weight. Tesco Groceries lists 22g protein in a 60g Grenade Fudged Up Fudge bar; PhD lists 21g in a 64g Choc Brownie Smart Bar, and Barebells UK lists 16g in a 55g Cinnamon Bun bar. | How much protein does the individual bar I plan to offer contain? A per-100g figure alone does not answer that question. |
| Labels and allergens | Keep the ingredients and allergen declaration accessible for each flavour, including any precautionary statements. Check whether the bars will remain in their original packs or be opened or repacked; the food-information requirements can differ. | I want customers to be able to read the label on the particular bar they choose, especially when several flavours are displayed together. |
| Outdoor storage | Follow the exact pack’s storage instructions and check its best-before date. Myprotein instructs customers to keep Lean Layered bars cool and dry, away from direct sunlight. | Will I have somewhere shaded and dry to keep the bars throughout the sale, rather than leaving them in direct sun? |
What can be easy to overlook?
-
Reading “low sugar” as “lower fat”
The two figures describe different parts of the nutrition panel. Tesco Groceries lists 1.3g sugar per 60g Grenade Fudged Up Fudge bar and 13g fat per 100g; PhD lists 1.2g sugar per 64g Choc Brownie bar and 14g fat per 100g.
If fat reduction matters, compare fat per 100g first. Then consider sugar and protein as separate figures.
-
Calling a comparatively lower-fat bar “low fat”
Myprotein’s Lean Layered comparison is relative to its cited typical protein bar. The two specified flavours still contain 8.1g or 8.6g fat per 100g, so the comparison should not be shortened into a different claim.
When describing a bar, retain the named flavour, its fat figure and the comparison basis rather than applying a “low fat” label yourself.
-
Separating a bar from its ingredient information
The cited Grenade, Barebells and Quest product information includes declared allergens or precautionary statements. A customer choosing from a mixed display needs the information for the particular bar, not a general description of the range.
Keep varieties in their original labelled packs and check the label before answering an ingredient question. If you intend to open or repack bars, check the food-information duties that apply to that method of sale.
-
Buying a case without planning its storage
A multipack still needs to be stored according to the individual product instructions. Myprotein specifies cool, dry storage away from direct sunlight for Lean Layered bars.
Check the dates and storage directions before buying cases, and plan a shaded, dry place for stock during the outdoor sale.
How do the brand examples differ?
These figures describe named bars and flavours, not every product made or sold by each brand.
Myprotein
Myprotein positions Lean Layered as a lower-fat alternative to its cited typical protein bar.
- Myprotein lists 8.1g fat per 100g for Cookie Dough and 8.6g for White Chocolate and Raspberry.
- The brand’s relative comparison, verified in October 2022, is not an independent comparison with every protein bar.
Grenade
The Fudged Up Fudge 60g bar is an example for comparing protein and sugar with fat as separate measures.
- Tesco Groceries lists 22g protein and 1.3g sugar per 60g bar.
- The same listing gives 13g fat per 100g and 17g polyols per bar; check its allergen declaration and precautionary statements.
PhD
PhD’s Choc Brownie Smart Bar is a 64g option with published per-bar protein and sugar figures.
- PhD lists 21g protein and 1.2g sugar per 64g Choc Brownie bar.
- PhD lists 14g fat per 100g for this flavour and warns that excessive consumption may cause laxative effects.
Barebells
The Cinnamon Bun Soft Protein Bar provides a 55g example for comparing a different format.
- Barebells UK lists 16g protein per Cinnamon Bun bar.
- It lists 16g fat per 100g; the bar contains milk and soy and carries precautionary allergen statements.
Quest
Quest’s S’Mores bar provides a further product-label example, using information from its US-market page.
- Quest Nutrition lists 21g protein and 7g fat per 60g S’Mores bar.
- Its US-market information declares milk, almonds and soy and notes shared equipment with peanuts and other tree nuts. Check the label on any bar offered in the UK.
Tesco
Tesco Groceries lists single bars and multipacks from several brands in its protein-bar category.
- Individual product listings can be used to check the nutrition and label information for a named bar.
- A place in the protein-bar category does not establish that a product has lower fat; compare the exact listing or pack.
Joybuy protein-bar options
These Grenade Soft Core 12-bar packs are options for offering individual portions at a car boot sale. If lower fat is the deciding factor, check the fat per 100g on the exact pack rather than treating protein-bar or low-sugar wording as a substitute.

Grenade Soft Core Double Chocolate, 12 × 50g
The 12 × 50g format offers individual portions for a refreshment stall. Check each bar’s label for its fat per 100g, ingredients, allergens and storage directions before deciding whether it suits the sale.
No image available
Grenade Soft Core Golden Caramel, 12 × 50g
The 12 × 50g format offers individual portions for a refreshment stall. Compare this flavour’s own fat per 100g and full label with other bars; do not assume that figures for another Grenade flavour apply to it.
Questions about choosing and selling bars
Does low sugar mean a protein bar has less fat?
No. Sugar and fat are separate nutrition figures. For example, Tesco Groceries lists 1.3g sugar per 60g Grenade Fudged Up Fudge bar but 13g fat per 100g, while PhD lists 1.2g sugar per 64g Choc Brownie bar and 14g fat per 100g. Compare the exact flavours on the same per-100g fat basis.
What does Myprotein’s lower-fat comparison tell me?
It compares specified Lean Layered flavours with Myprotein’s cited typical protein bar, not with every bar on sale. Myprotein reports 8.1g fat per 100g for Cookie Dough and 8.6g for White Chocolate and Raspberry; its relative comparison was verified in October 2022. Keep the flavour and comparison basis with any description of the difference.
Can I offer sealed protein bars at a car boot sale?
Sealed, manufacturer-labelled bars let customers read the information on the item they are buying, but the packaging alone does not settle the rules for a particular stall. Check the organiser’s conditions and ask the relevant local authority about your setup; if you are operating a food business, consult Food Standards Agency registration guidance before trading.
What should I do about allergens when displaying several flavours?
Keep each flavour’s label available and check it before answering a customer’s question; allergen declarations and precautionary statements can differ. GOV.UK allergen guidance says food businesses in England, Northern Ireland and Wales must provide allergen information for both prepacked and non-prepacked food and drink. Check the requirements for how you intend to offer the bars, particularly if opening or repacking them.
How should I store bars during an outdoor sale?
Follow the instructions for the exact product and plan storage before setting up the stall. Myprotein instructs customers to keep Lean Layered bars cool and dry, away from direct sunlight, so a shaded, dry storage place matters for that product.
