Calorie-aware lunch packers
If cheese, bread and accompaniments are already in your ploughman’s lunch, use the whole-bar calorie figure to decide whether a bar fits as another component. A low-sugar claim does not answer that question.
Who is this choice for?
Protein-priority lunch snackers
If the bar’s protein amount matters more to your choice, compare grams of protein alongside calories. A full-size bar can add more protein than a smaller example, but it also needs to fit the rest of your lunch.
Shoppers with allergies or dietary exclusions
Check the exact flavour’s ingredients, highlighted allergens and precautionary statements. For example, Grenade lists milk, soy and peanuts for Peanut Nutter, while Barebells advises checking each product’s allergen label.
What should you compare?
Start with the bar’s whole-serving figures, then decide what role it will play alongside the cheese, bread and other lunch foods.
| Priority | What to check | Your needs |
|---|---|---|
| Whole-bar calories | Check kcal for the complete bar, not just per 100 g or a smaller stated serving. Compare that figure with the other lunch components. | I’m adding a bar to cheese and bread, so I want to know its full contribution to my lunch. |
| Protein amount | Read protein grams and kcal on the same per-bar basis. Barebells states 10 g protein and 138 kcal for its 40 g Banana Choco bar; Grenade states 20 g and 218 kcal for its 60 g Peanut Nutter bar. | If protein is my main reason for adding a bar, I can compare the extra protein with the calories it brings. |
| Portion and flavour | Check bar size, pack size and the nutrition panel for the flavour you intend to eat. Do not assume another flavour has the same figures. | For a packed lunch, I want a portion I can carry and include without mistaking a multipack’s details for one bar’s serving. |
| Ingredients and allergens | Read the current ingredients, highlighted allergens and any precautionary statements for the exact product. Check dietary suitability on that pack. | When I change brands or flavours, I need to know whether that specific bar meets my dietary requirements. |
What can catch you out?
-
Reading “low sugar” as “low calorie”
Sugar and energy are different label figures. Grenade lists 218 kcal per Peanut Nutter bar despite marketing it as a low-sugar product.
Compare kcal for the whole bar first; then consider sugar, protein and ingredients if they matter to your choice.
-
Choosing more protein than you wanted from an add-on
In the manufacturer examples, the 20 g-protein Grenade Peanut Nutter bar has more calories per bar than the smaller Barebells Banana Choco and Myprotein Peanut Butter bars, which provide 10 g and 8 g protein respectively.
Decide whether you want a smaller sweet addition or a larger protein contribution, then compare both figures per bar.
-
Overlooking the exact flavour’s allergens
Grenade’s Peanut Nutter ingredients include milk, soy and peanuts. An ingredient list for one bar cannot establish the contents of another flavour.
Read the current pack’s ingredients, highlighted allergens and precautionary statements whenever you switch products.

Relying on a category listing for product details
A retailer’s protein-bar category helps you find options, but its assortment and offers can change by date or location.
Use the exact product page or pack to check the flavour, nutrition information and availability before choosing.
Brand and retailer references
These examples illustrate different bar formats and places to compare them; a brand name alone does not establish a bar’s calories or suitability.
Barebells
Barebells offers several bar formats. Its Banana Choco chewy bar is listed by the manufacturer at 138 kcal and 10 g protein per 40 g bar.
- The stated 40 g portion offers a smaller-format comparison for a lunch add-on.
- Barebells advises checking each product’s allergen label; figures for Banana Choco do not describe every flavour.
Myprotein
Myprotein sells bars in several formats. Its Peanut Butter Protein Bar lists 193 kcal and 8 g protein per 38 g bar on the UK product page.
- The product page describes this particular bar as suitable for vegetarians and vegans.
- Its stated protein amount is lower than the 20 g in Grenade’s Peanut Nutter example; compare calories as well as protein.
Grenade
Grenade’s Peanut Nutter is a full-size example listed at 218 kcal and 20 g protein per 60 g bar.
- Its stated protein amount gives a point of comparison for shoppers prioritising protein quantity.
- The Peanut Nutter ingredients include milk, soy and peanuts; its figures and ingredients should not be applied to other Grenade bars.
PhD
PhD lists a 32 g Smart Bar Half Size at 131 kcal and 10 g protein per serving on its EU store page.
- The stated half-size portion provides a format to compare with full-size bars.
- That EU listing does not establish current UK availability or that a UK pack has the same recipe and figures.
Quest
Quest describes protein bars with 20 g protein on its official US-facing range page.
- The range offers a protein-quantity comparison to investigate if you encounter an individual bar in a UK shop.
- The US-facing information does not establish a UK recipe or current UK availability; check the specific UK pack.
Tesco
Tesco is a retailer, not a protein-bar manufacturer. Its grocery category lists bars from multiple brands.
- A category listing can help you find individual bars while shopping for lunch ingredients.
- Check the exact product label and local availability rather than assuming the category listing establishes either.

Questions about lunch and protein bars
How do I compare a bar’s calories with my ploughman’s lunch?
Use kcal for the entire bar and consider it alongside the cheese, bread and accompaniments you intend to eat. Manufacturer figures for three distinct examples are 138 kcal for a 40 g Barebells Banana Choco bar, 193 kcal for a 38 g Myprotein Peanut Butter bar and 218 kcal for a 60 g Grenade Peanut Nutter bar; those figures are not a calorie threshold for all protein bars.
Does low sugar mean fewer calories?
No: sugar and energy are different figures. Grenade markets Peanut Nutter as low sugar but lists 218 kcal per bar, so check the whole-bar kcal figure if calories are guiding your lunch choice.
Should I choose the bar with the most protein?
Choose by the role you want the bar to play in lunch, comparing protein and calories on the same per-bar basis. Barebells lists 10 g protein and 138 kcal for Banana Choco, while Grenade lists 20 g protein and 218 kcal for Peanut Nutter; neither figure describes every bar from those brands.
Do I need to check allergens for each flavour?
Yes. Read the current ingredients, highlighted allergens and precautionary statements for the exact flavour and pack: Grenade’s Peanut Nutter ingredients include milk, soy and peanuts, and Barebells advises checking individual product allergen labels.
