Festival-goers comparing calories
If you are packing a bar for a day outdoors, compare the calories in the complete bar rather than choosing by its protein claim alone. Bar weights differ, so the per-100 g figure answers a different question.
Who is this for?
Shoppers prioritising protein
A larger, confectionery-style bar may provide more protein alongside more calories. Compare both per-bar figures, then check sugars and polyols if those affect your choice.
People checking dietary suitability
Read the ingredients and allergen statements on the exact flavour before packing it. A vegan label, a low-sugar claim or familiarity with the brand does not replace that check.
What should you check?
Start with the figures for one complete bar, then check whether its ingredients and pack instructions suit a day away from home.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per bar | Compare kcal for the complete bar and note its weight. Check the exact flavour’s label, as values can vary between flavours. | I want to know what one packed bar contributes, rather than judging it by a low-sugar or high-protein claim. |
| Protein | Read grams of protein alongside kcal per bar. For example, Myprotein lists 18 g protein and 152 kcal for its 45 g Cookie Dough Lean bar; Tesco lists 23 g and 215 kcal for the 60 g Grenade White Chocolate Cookie bar. | More protein matters to me, but I also want to see the calorie difference before choosing the larger bar. |
| Sugars and polyols | Check sugars and polyols separately from calories. Tesco lists 1.7 g sugars and 16 g polyols per Grenade White Chocolate Cookie bar; the PhD nutrition basis lists 20 g polyols per 64 g Smart Bar. | I may prefer less sugar, but I do not want to assume that means fewer calories or overlook an unfamiliar sweetener. |
| Ingredients and allergens | Read the exact pack’s ingredients and any ‘may contain’ statement. Check dietary labels against the particular flavour, not the range as a whole. | If an ingredient or potential allergen matters to me, I need that information before taking the bar to the festival. |
| Practical packing | Check the pack’s storage instructions and whether the bar is individually wrapped. Consider trying an unfamiliar flavour before relying on several bars during the event. | I want a snack I can carry and am willing to eat, without discovering on the day that the flavour or ingredients do not suit me. |
Common buying mistakes
-
Assuming high protein or low sugar means fewer calories
Products with similar front-of-pack claims can differ in bar weight and total calories. Myprotein lists 152 kcal for its 45 g Cookie Dough Lean bar, while Tesco lists 215 kcal for the 60 g Grenade White Chocolate Cookie bar.
Compare kcal, protein and sugars on a whole-bar basis before deciding which trade-off suits your snack.
-
Overlooking polyols in an unfamiliar bar
Tesco lists 16 g polyols per Grenade White Chocolate Cookie bar, and the cited PhD Smart Bar nutrition basis lists 20 g per 64 g bar. Individual tolerance can vary.
Read the ingredients and pack warnings, and try an unfamiliar product before making it your only packed snack.
-
Treating a range label as an allergen check
Ingredients can differ between products and flavours. Barebells, for example, states that its vegan Caramel Peanut bar contains wheat protein and therefore gluten.
Check the exact pack’s ingredients and precautionary allergen statement. The Food Standards Agency explains that ‘may contain’ labelling signals that a regulated allergen could be unintentionally present.
Brand references for comparing bars
Myprotein
Its Lean Protein Bar provides a lower-calorie example for a whole-bar comparison.
- Myprotein lists 152 kcal, 18 g protein, 1.2 g sugars and 5.7 g fibre for the 45 g Cookie Dough bar.
- Values can vary by flavour. Check the exact product’s dietary information, allergens and excessive-consumption warning.
Grenade
The White Chocolate Cookie bar listed by Tesco illustrates a larger bar with more protein per serving.
- Tesco lists 23 g protein and 1.7 g sugars per 60 g White Chocolate Cookie bar.
- The same bar has 215 kcal and 16 g polyols. Check its allergen and ‘may contain’ information on the pack.
PhD
Its Smart Bar is another protein-focused format to compare by whole-bar nutrition.
- PhD lists 20 g protein and 238 kcal for the cited 64 g Smart Bar nutrition basis.
- That nutrition basis also lists 20 g polyols. Check the exact flavour’s figures and ingredients.
Barebells
Barebells offers original, soft and vegan protein-bar formats.
- The separate formats give shoppers product labels to compare for their preferred snack style.
- Do not assume every product has the same dietary suitability: Barebells states that its vegan Caramel Peanut bar contains wheat protein and gluten.
Quest
Quest presents protein-focused bars as on-the-go snacks.
- Quest says its OG Protein Bars contain up to 21 g protein per bar.
- Quest says its bars contain sugar alcohols and tolerance varies. Check a UK pack for the exact product’s nutrition and ingredients.
Tesco
Tesco is a retailer where shoppers can compare protein bars from different manufacturers.
- Its protein-bar category listed products from several brands, including Grenade and Barebells.
- Check the current listing and local availability for the particular bar you intend to buy.

Questions about festival snacks
How do I compare protein bars when calories matter most?
Compare kcal per complete bar, then read protein and bar weight alongside it. Myprotein lists 152 kcal per 45 g Cookie Dough Lean bar, Tesco lists 215 kcal per 60 g Grenade White Chocolate Cookie bar, and PhD lists 238 kcal per 64 g bar for its cited Smart Bar nutrition basis. Check the exact flavour, because formulations can differ.
Should I check polyols in a low-sugar bar?
Yes, especially if the bar is unfamiliar. Tesco lists 16 g polyols in the Grenade White Chocolate Cookie bar, while PhD’s cited 64 g Smart Bar nutrition basis lists 20 g. Individual tolerance varies, so read the pack warnings and consider trying the product before the festival.
What allergen information should I read before packing a bar?
Check the exact bar’s ingredients and any ‘may contain’ statement, including when you have bought another flavour from the same brand before. The Food Standards Agency explains that precautionary allergen labelling communicates that a regulated allergen could be unintentionally present.
