Who is choosing?

Calorie-conscious elevenses shoppers

If you want a portable mid-morning bar without choosing a larger portion by accident, compare kcal per whole bar alongside its weight and protein content.

Workers choosing protein between meals

If a bar needs to fit a commute or work break, decide whether a smaller portion or more protein per bar matters more to you. The two do not necessarily come in the same product.

Shoppers checking ingredients closely

Check the individual flavour’s wrapper for allergens and sweeteners. The Myprotein and Grenade examples have different ingredient warnings, so a brand name alone is not enough to judge a particular bar.

What should you compare?

Start with the whole-bar portion, then weigh the protein figure against the ingredients and dietary information for the flavour you would buy.

Priority What to check Your needs
Portion and calories Read kcal for the complete bar and its weight. Myprotein lists 152 kcal per 45g Cookie Dough Lean bar; Grenade lists 218 kcal per 60g Peanut Nutter bar. I want a smaller mid-morning snack, so the figure for the bar I will actually eat matters more than a front-of-pack claim.
Protein Compare grams per whole bar alongside kcal. Myprotein lists 18g for its 45g Lean bar; Grenade lists 20g for its 60g Peanut Nutter bar. On some days I may prefer the larger bar for its portion and protein amount; on others, I would choose the lighter example.
Sugar and sweeteners Check sugar per bar separately from calories, and read any sweetener or excessive-consumption warning. Grenade lists 1.7g sugar for Peanut Nutter, which has 218 kcal per bar. I may want to compare sugar, but I would not use a low sugar figure as a substitute for checking calories or ingredients.
Ingredients and suitability Read the current flavour’s ingredients, allergen statement and dietary-suitability information. The Myprotein Lean Cookie Dough example is labelled not suitable for vegetarians. If an ingredient or dietary restriction matters to me, I need to check the exact bar rather than assume that every flavour in a range is alike.

Common buying mistakes

  • Treating low sugar or high protein as low calorie

    Grenade lists 1.7g sugar and 20g protein for its Peanut Nutter bar, but also 218 kcal per 60g bar. Myprotein lists 152 kcal for its smaller, 45g Lean Cookie Dough bar.

    Compare kcal and protein for each complete bar, keeping the different portion sizes in view.

  • Assuming a fitness-branded bar suits every allergy

    The checked Myprotein Lean Cookie Dough bar lists milk, soya and wheat-containing ingredients. Grenade Peanut Nutter contains peanuts, milk and soya and carries further possible-trace warnings.

    Read the current wrapper for the particular flavour before buying or eating it; do not rely on another bar’s ingredients.

  • Missing sweetener warnings

    The Myprotein Lean and Grenade Peanut Nutter product pages both warn that excessive consumption may have a laxative effect.

    Check the ingredient list and wrapper warning, particularly if you are considering more than one bar.

  • Applying another market’s label to a UK bar

    Product ranges and flavours need to be checked at the variant level; a retailer’s category listing does not give the complete ingredients and nutrition panel for every bar.

    For a specific UK purchase, use the current product label to check portion size, kcal, allergens and dietary suitability.

Brand references

These brand examples illustrate different bar formats and label checks; they are not a ranking or a list of Joybuy stock.

Myprotein

The Lean Protein Bar is one smaller-format example for comparing a whole-bar portion at elevenses.

  • Myprotein lists 152 kcal and 18g protein per 45g Cookie Dough bar.
  • Nutrition varies by flavour. The checked Cookie Dough bar is not suitable for vegetarians; check its ingredients and excessive-consumption warning.

Grenade

Peanut Nutter provides a larger bar to compare with a lighter elevenses portion.

  • Grenade lists 20g protein and 1.7g sugar per 60g Peanut Nutter bar.
  • The same bar has 218 kcal and contains peanuts, milk and soya. Check its possible-trace and excessive-consumption warnings.

PhD

Smart Bar Half Size is a smaller-format option to assess by its exact flavour and market label.

  • PhD’s EU listing gives 10g protein and 131 kcal per 32g serving.
  • That EU listing does not establish the nutrition details or availability of a particular UK pack.

Barebells

The range includes original and soft-bar formats; Tesco lists several 55g Soft Protein Bar flavours in the UK.

  • The UK listings provide specific flavours and pack sizes to look for when comparing labels.
  • Barebells says its products are not low- or reduced-calorie foods. Its checked nutrition page is US-market material, so use the UK pack for the flavour’s figures.

Quest

Quest describes a protein-bar range made with dairy-based proteins.

  • Quest’s range information identifies dairy-based proteins and sugar alcohols as ingredients to consider.
  • The checked range page is not UK-specific; assess the nutrition and ingredients on the particular UK pack.

Tesco

Tesco is a retailer whose UK protein-bar category lists several brands and formats.

  • Its listings can help identify a particular flavour and pack format to compare.
  • A category listing does not replace the individual bar’s ingredients, allergen statement or nutrition panel.

Frequently asked questions

How should I compare calories in protein bars for elevenses?

Compare kcal per complete bar, while noting its weight. Myprotein lists 152 kcal per 45g Lean Cookie Dough bar and Grenade lists 218 kcal per 60g Peanut Nutter bar; the first is the lighter of these two portions, but they differ in size and protein content.

Should I choose the bar with the most protein?

Not on protein alone. Myprotein’s 45g Lean Cookie Dough bar lists 18g protein and 152 kcal, while Grenade’s 60g Peanut Nutter lists 20g protein and 218 kcal. Decide whether the larger portion and additional protein fit what you want from elevenses.

Is a low-sugar protein bar suitable if I have an allergy?

A low sugar figure cannot establish allergy suitability; read the current bar’s ingredients and allergen statement. The checked Myprotein Lean Cookie Dough example lists milk, soya and wheat-containing ingredients, while Grenade Peanut Nutter contains peanuts, milk and soya and carries possible-trace warnings.

Why do some protein bars carry a laxative-effect warning?

The checked Myprotein Lean and Grenade Peanut Nutter product pages warn that excessive consumption may have a laxative effect. Read the particular bar’s ingredients and warning, especially if you plan to eat more than one.

Can I assume a protein bar is vegetarian or vegan?

No. The checked Myprotein Lean Cookie Dough bar is labelled not suitable for vegetarians. Check the dietary-suitability statement and ingredients on the exact flavour and pack you intend to buy.
