Gamers looking for a small desk snack
If you mainly want a portioned sweet snack, a lighter bar may fit that role without providing much protein. Myprotein UK lists 92 kcal and 4.8 g protein for its 30 g Double Chocolate Cereal Bar.
Who is this choice for?
Shoppers who want more protein from a sweet snack
Compare protein and kcal for the whole bar, not just the front-of-pack description. The Myprotein UK bars listed here range from 4.8 g to 18 g protein, with different serving sizes and calorie figures.
Shoppers checking ingredients or dietary suitability
Read the exact flavour’s pack if allergens, vegetarian suitability or sweetener warnings affect your choice. Myprotein UK states that its Lean Layered and Lean Protein bars are not suitable for vegetarians, while its Cereal Bar is suitable for vegetarians.
What should you compare?
Decide whether the bar is chiefly a small sweet snack or a protein-focused snack, then compare labels using the same whole-bar serving basis.
| Priority | What to check | Your needs |
|---|---|---|
| Whole-bar calories | Check kcal for the entire bar and its serving weight. Myprotein UK lists 92 kcal for a 30 g Double Chocolate Cereal Bar, fewer than 140 kcal for a Lean Layered Bar and 152 kcal for a 45 g Cookie Dough Lean Protein Bar; the flavours and portions are not identical. | I want a snack that fits the calorie allowance I have chosen for a gaming session, without mistaking a smaller bar for an equivalent full-size portion. |
| Protein per bar | Read grams of protein alongside kcal for the same bar. Myprotein UK lists 4.8 g for its Double Chocolate Cereal Bar, 15 g for Lean Layered and 18 g for its Cookie Dough Lean Protein Bar. | If protein is the reason I am buying a bar, I want to know how much the whole portion provides before choosing the lightest one. |
| Sugar and sweeteners | Compare the exact flavour’s sugars, ingredients and any excessive-consumption warning. A low-sugar description does not tell you the calorie figure: PhD lists 250 kcal for its 64 g Choc Brownie Smart Bar. | I may prefer a low-sugar bar, but I still want to check its whole-bar calories and whether its sweeteners suit me. |
| Allergens and suitability | Read the ingredients, allergen declaration, precautionary statements and vegetarian or vegan suitability on the exact pack. The Food Standards Agency explains that precautionary allergen labelling signals that an allergen could be unintentionally present. | For an allergy or dietary restriction, I need the information for the flavour I will eat, rather than assuming every bar in a range has the same ingredients. |
What is easy to overlook?
-
Assuming low sugar means low calories
Those are different label measures. PhD lists 250 kcal for its 64 g Choc Brownie Smart Bar, and Barebells says its bars are not low- or reduced-calorie foods.
Start with kcal per whole bar, then compare protein, sugars and serving weight for the flavours you are considering.
-
Choosing the lightest bar when you want more protein
Myprotein UK lists 4.8 g protein for its 92 kcal Double Chocolate Cereal Bar, compared with 15 g for Lean Layered at fewer than 140 kcal and 18 g for its 152 kcal Cookie Dough Lean Protein Bar.
Decide which matters more for this snack—a smaller portion or a larger protein amount—before comparing bars.
-
Relying on a range name instead of the exact pack
Ingredients and nutrition can differ by flavour. Some bars reviewed here also carry warnings that excessive consumption may cause laxative effects.
Check the flavour’s nutrition table, ingredients, allergen statements and warnings before eating it.
Brand and product-line references
These examples illustrate different portion and protein choices; a brand name alone does not establish the nutrition of every flavour.
Myprotein
Its UK product pages show several distinct snack portions, from the 30 g Double Chocolate Cereal Bar to Lean Layered and Lean Protein bars.
- Myprotein UK lists 92 kcal and 4.8 g protein for the Double Chocolate Cereal Bar, 15 g protein at fewer than 140 kcal for Lean Layered, and 152 kcal with 18 g protein for the 45 g Cookie Dough Lean Protein Bar.
- Lean Layered and Lean Protein are stated as not suitable for vegetarians and carry excessive-consumption laxative-effect warnings. Check the chosen flavour’s label.
Grenade
Grenade describes its protein-bar range as high in protein and low in sugar.
- The range includes several flavours and pack formats for shoppers comparing confectionery-style bars.
- Use the exact bar’s nutrition table to judge calories; the range’s low-sugar positioning does not supply a whole-bar calorie figure.
PhD
Smart Bar is a full-size protein-bar option where the whole-bar calorie figure matters alongside protein.
- PhD lists 21 g protein and 250 kcal for a 64 g Choc Brownie Smart Bar.
- That flavour is a different portion and calorie choice from the smaller Myprotein examples. PhD also carries an excessive-consumption laxative-effect warning.
Barebells
Barebells describes its bars as high in protein with no added sugar, while stating that they are not low- or reduced-calorie foods.
- Its nutrition information gives whole-bar figures that can be checked alongside serving size.
- The cited Barebells nutrition information is US-market material; use the exact UK pack label for a UK nutrition comparison.
Quest
Quest’s S'Mores bar provides a full-size comparison, but its cited product information is for the US market.
- Quest Nutrition lists 190 calories and 21 g protein for a 60 g S'Mores bar on its US product page.
- Those figures do not confirm an equivalent UK formulation or UK availability. Check a UK pack before using them for a local purchase decision.

Common questions
How do I compare lower-calorie protein bars for gaming?
Compare kcal and protein per whole bar against the portion you want, rather than using one calorie cutoff for every snack. Myprotein UK lists 92 kcal and 4.8 g protein for its 30 g Double Chocolate Cereal Bar, fewer than 140 kcal and 15 g protein for Lean Layered, and 152 kcal with 18 g protein for its 45 g Cookie Dough Lean Protein Bar.
Is a low-sugar protein bar necessarily low in calories?
No. Sugar and calories are different label measures: PhD lists 250 kcal for its 64 g Choc Brownie Smart Bar despite positioning the range as low in sugar. Check kcal for the whole bar before comparing sugars or protein.
Can I choose a protein bar as a gaming snack if I do not train?
You can choose one as a snack without treating it as a gaming necessity. Decide whether you want a small sweet portion or a particular amount of protein, then check the whole-bar nutrition and ingredients against that choice.
What should I check if I have a food allergy?
Read the ingredient list, allergen declaration and any precautionary statement on the exact flavour and pack before eating it. The Food Standards Agency explains that precautionary allergen labelling communicates that an allergen could be unintentionally present; a range name cannot tell you whether a particular bar is suitable.
Why do some bars warn about excessive consumption?
The Myprotein UK Lean bars and some PhD products carry warnings that excessive consumption may cause laxative effects. Read the warning on the bar you choose, particularly if you expect to eat more than one portion.
