Cinema-goers with a defined snack allowance
If you have a calorie ceiling in mind, compare the whole bar rather than a per-100g figure or a front-of-pack protein claim. Bar sizes differ, so the portion you will actually eat matters.
Who these choices suit
The useful starting point is whether your limit is the bar’s calories, its ingredients or simply whether you can take it into the screening.
Shoppers weighing protein against bar size
Tesco’s listings show the trade-off: Grenade Salted Caramel 35g is labelled under 150kcal with 12g protein, while Fulfil Chocolate Brownie 55g contains 186kcal with 18.9g protein. Choose using both figures, not protein alone.
Shoppers checking dietary suitability
Vegan, dairy-free, gluten-free and no-added-sugar descriptions answer different questions. Read the exact pack’s ingredients, allergen statements and nutrition panel, particularly when peanuts, milk, soya or polyols matter to you.
What to compare before buying
Set a calorie allowance for the whole bar first. Then compare protein and ingredients on that same per-bar basis, before checking whether the venue permits your snack.
| Priority | What to check | Your needs |
|---|---|---|
| Whole-bar calories | Read the energy value for one complete bar and its weight. Tesco lists Grenade Salted Caramel 35g at under 150kcal, but gives an upper limit rather than an exact calorie figure. | I want the bar I take into the film to fit my own snack allowance, without having to calculate it from a smaller serving. |
| Protein alongside energy | Compare grams of protein and kcal for the same whole bar. Tesco lists Fulfil Chocolate Brownie 55g at 18.9g protein and 186kcal, and Chocolate Peanut Butter 55g at 20g and 206kcal. | I would accept a larger bar if its protein amount matters more to me than choosing the lowest disclosed calorie figure. |
| Ingredients and labels | Check sugars, polyols, ingredients and allergen statements on the exact flavour; low sugar does not establish low calories. In Glanbia Nutrition’s survey, 78% of UK bar consumers said they checked nutrition and ingredient labels at least sometimes. | Milk, soya, peanuts or polyols may change which bar I choose. Glanbia’s figure concerns UK bar consumers generally, not specifically cinema-goers or protein-bar buyers. |
| Portability and venue rules | Choose a portion you can carry and eat without preparation, then check the policy for your particular cinema. ODEON permits outside snacks at most of its venues but names an exception at Islington Luxe & Dine. | I want an easy-to-carry snack for an outing. In Glanbia Nutrition’s survey of over 800 UK and Irish bar consumers, 49% named “easy to grab and go” and 48% named “convenient” as reasons for choosing bars; respondents could give more than one reason, and the results were not cinema-specific. |
Mistakes to avoid
-
Using “low sugar” as a shortcut for low calories
Tesco lists PhD Smart Protein Bar Chocolate Brownie at 1.2g sugar but 250kcal per 64g bar. Sugar and energy measure different things.
Check kcal for the whole bar first, then compare protein, sugars and ingredients.
-
Assuming a dietary claim settles an allergy question
Tesco labels the nākd Peanut Butter Protein Bar vegan, dairy-free and gluten-free, but it contains peanuts and may contain soya and nuts.
If you need to avoid an ingredient, read the current pack’s ingredients and allergen statements rather than relying on a front-of-pack description.
-
Overlooking polyols before a long screening
Tesco lists 17.8g polyols in a Fulfil Chocolate Brownie 55g bar and 14g in its Chocolate Peanut Butter 55g bar. Its PhD Chocolate Brownie listing warns that excessive consumption may cause laxative effects.
Check the exact bar’s label and consider whether its ingredients are familiar to you before taking it to the cinema.
-
Assuming every cinema accepts outside snacks
ODEON says guests may bring their own snacks and drinks, excluding heated food, pungent food and alcohol. It does not allow outside food at ODEON Islington Luxe & Dine.
Check the policy for the exact venue you plan to visit before bringing a bar.
Brand and retailer references
These examples describe particular bars or ranges, not every product carrying the same name. Compare the nutrition panel for the flavour and size you intend to buy.
Grenade
Its Tesco-listed Salted Caramel 35g bar offers a smaller-portion reference for a calorie-led choice.
- Tesco labels this specific bar under 150kcal, with 12g protein and 0.9g sugar.
- The under-150kcal statement is not an exact energy value and does not describe every Grenade flavour or size.
PhD
The Tesco-listed Chocolate Brownie Smart Protein Bar illustrates a choice where protein takes precedence over a tighter calorie allowance.
- The 64g bar is listed at 21g protein and 1.2g sugar.
- It contains 250kcal per bar; Tesco also lists milk and soya, a possible gluten-containing-cereals warning and an excessive-consumption laxative-effects warning.
Myprotein
Its High-Protein Bar is a protein-first reference rather than a basis for assuming a particular calorie allowance.
- Myprotein states 30g protein and 23g carbohydrates per bar.
- Myprotein says nutrition varies by flavour; check the selected flavour’s per-bar energy before comparing it with other snacks.
Quest
Quest describes its OG Protein Bars as gluten-free and made with dairy-based proteins.
- Quest states that bars in this range contain up to 21g protein.
- Quest says its bars contain sugar alcohols and that tolerance varies. Check the UK pack for the chosen flavour’s calories and allergen information.
Barebells
Its UK Caramel Cashew page provides protein and added-sugar information for shoppers comparing confectionery-style bars.
- Barebells states that Caramel Cashew contains 20g protein and no added sugar.
- No-added-sugar wording does not give its calorie value; read the selected bar’s nutrition panel before treating it as a lower-calorie option.
Tesco
Tesco is the retailer for several of the product-specific nutrition examples above, not the manufacturer of those bars.
- Its listings allow per-bar figures to be compared across the cited Grenade, Fulfil, nākd and PhD products.
- Check the current listing and pack for the precise flavour and size you intend to purchase.
Protein bars on Joybuy
These Grenade multipacks offer chocolate, caramel and peanut-flavoured options for shoppers considering a bar to take to the cinema. Check the nutrition and allergen information for the particular bar: the Tesco-listed Salted Caramel 35g figures above do not describe these different Grenade products.

Common questions
Can I take a packaged protein bar into an ODEON cinema?
ODEON says guests may bring their own snacks and drinks, but not heated food, pungent food or alcohol. ODEON Islington Luxe & Dine does not allow outside food, so check the policy for your exact venue before travelling.
How do I choose a lower-calorie protein bar for a film?
Decide on a calorie allowance for the whole bar, then compare protein, sugars, polyols and allergens for that same portion. Tesco’s listings illustrate the range: Grenade Salted Caramel 35g is labelled under 150kcal with 12g protein, while Fulfil Chocolate Brownie 55g contains 186kcal with 18.9g protein.
Does low sugar mean a protein bar is low calorie?
No. Tesco lists PhD Chocolate Brownie 64g at 1.2g sugar but 250kcal per bar. Read the whole-bar energy value separately from its sugar and protein figures.
Which cited bar is vegan and dairy-free?
Tesco labels its nākd Peanut Butter Protein Bar suitable for vegans, dairy-free and gluten-free. It contains peanuts and may contain soya and nuts, so check the current pack if allergens matter to you.
Why check polyols in a low-sugar bar?
Polyols appear in some low-sugar bars, and tolerance can vary. Tesco lists 17.8g polyols per Fulfil Chocolate Brownie 55g bar and carries an excessive-consumption laxative-effects warning for PhD Chocolate Brownie; check the exact product label before choosing a bar for a screening.
