For car boot sale refreshments, compare the calories in a whole bar before deciding whether its protein content suits the snack you want to offer. Tesco lists a 45g Barebells Pistachio Spread bar at 171 kcal and 15g protein, while its 64g PhD Chocolate Brownie bar has 250 kcal and 21g protein. Keep each bar’s original label available for ingredients, allergens and warnings, and check the rules for your planned sale before buying stock.
Individually wrapped bars let buyers check the manufacturer’s ingredients, allergen information and nutrition label. If you plan to sell food, check the event organiser’s conditions and ask the local authority whether your activity requires food-business registration.
The whole-bar figure matters when one bar is the serving. Tesco lists Barebells Pistachio Spread 45g at 171 kcal and Barebells Cinnamon Bun 55g at 198 kcal; its PhD Chocolate Brownie 64g listing gives 250 kcal.
Compare protein and calories together rather than relying on a high-protein or low-sugar description. The Tesco examples range from 15g protein in a 171 kcal bar to 21g in a 250 kcal bar.
Start with the serving you would actually offer, then check protein, the individual label and the conditions for selling at the event.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per bar | Read the kcal figure for the complete bar and its weight. Compare bars on that basis, not on low-sugar wording alone. | I want each bar to fall within the calorie range I plan to offer, so I need the figure for one whole bar. |
| Protein alongside energy | Compare grams of protein and kcal for the same serving. Tesco lists 15g protein and 171 kcal for Barebells Pistachio Spread 45g, versus 21g and 250 kcal for PhD Chocolate Brownie 64g. | If protein matters more to me than staying below 200 kcal per bar, the larger serving may still be worth considering. |
| Ingredients and warnings | Check each flavour’s current ingredient and allergen label. Read any sweetener or excessive-consumption warning on the individual pack. | Buyers need to see the exact wrapper before choosing a bar, especially when ingredients or allergens affect their choice. |
| Event-sale requirements | Confirm that individual wrappers will remain intact and legible. Ask the organiser about stall conditions and the local authority whether your planned food sales require registration. | Before I buy stock for resale, I need to know which requirements apply to my event and activity. |
Sugar wording does not tell you the energy in a whole bar. Tesco’s reviewed protein-bar listings show different calorie totals across bar sizes and recipes.
Use the current pack’s kcal-per-bar figure when comparing refreshments. Check applicable nutrition-claim rules before using calorie-related marketing wording.
Removing or obscuring a wrapper can leave buyers without the ingredients, allergen information and warnings for that particular flavour.
Keep original wrappers intact and accessible. If you intend to repackage bars, check the labelling requirements for that activity before doing so.
GOV.UK and Food Standards Agency guidance includes temporary stalls among premises that can be used by food businesses. The requirements for a particular car boot sale also depend on the planned activity and event.
Ask the organiser about food-selling conditions and check with the local authority whether your proposed trading requires registration.
The Tesco listings for Barebells Cinnamon Bun and PhD Chocolate Brownie warn that excessive consumption may have laxative effects. A warning on one flavour should not be assumed to describe every bar.
Keep the exact product label available and avoid suggesting that several bars can be consumed without regard to its warnings.
Two individual bars listed by Tesco provide useful comparisons when calories per whole bar are the starting point.
The Smart Bar examples suit a comparison where protein content matters alongside, rather than instead of, calories.

Check the applicable nutrition-claim rules before using calorie-related marketing wording; a low-sugar description alone does not establish low energy. You can compare stated per-bar figures accurately: Tesco lists Barebells Pistachio Spread 45g at 171 kcal per bar, for example.
Choose according to which figure matters more for the refreshment you plan to offer. Tesco lists Barebells Pistachio Spread 45g at 171 kcal and 15g protein, while PhD Chocolate Brownie 64g has 250 kcal and 21g protein; check the current label of the bar you buy.

The individual wrapper lets buyers check that bar’s ingredients, allergens, nutrition information and warnings. If you plan to repackage bars for direct sale, check the labelling requirements for that activity rather than assuming the original outer pack is enough.
No. Sugar wording does not settle calorie, allergen or sweetener questions. Check the exact flavour’s wrapper: the Tesco listings for Barebells Cinnamon Bun and PhD Chocolate Brownie include warnings about excessive consumption.
