Desk snackers watching portion size
If a bar is one part of your working day rather than a meal, compare calories for the whole bar before deciding whether its protein and fibre suit the snack you want.
Who is choosing an office snack?
Workers who want a portable protein snack
An individually wrapped bar is convenient to bring to work. Compare protein alongside calories: a larger protein figure does not, on its own, settle which portion suits you.
Buyers checking ingredients and dietary suitability
For a vegan requirement, an allergy or a shared workplace, check the selected flavour’s current ingredients, dietary statement and precautionary allergen wording before bringing it in.
What should you compare?
Start with the portion you will actually eat, then compare protein, ingredients and dietary suitability on that same bar.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per bar | Read kcal for the complete bar, not only per 100 g. Myprotein UK lists 152 kcal for its 45 g Lean Cookie Dough bar; Tesco lists 159 kcal for a 44 g TREK Choc Caramel bar. Barebells lists 203 kcal for its 55 g Salty Peanut bar. | I want a portion that fits the snack I have in mind, without assuming that high protein or no added sugar means fewer calories. |
| Protein and fibre | Compare grams per whole bar alongside kcal. Myprotein UK lists 18 g protein for Lean Cookie Dough; Tesco lists 12 g protein and 12 g fibre for TREK Choc Caramel. PhD lists 21 g protein and 250 kcal for its 64 g Choc Brownie Smart Bar. | If protein is my main reason for choosing a bar, I want to see what the full portion provides. Fibre or a smaller portion may also matter to my choice. |
| Dietary fit and allergens | Check the exact flavour’s ingredients, suitability statement and ‘may contain’ wording. Tesco marks TREK Choc Caramel suitable for vegans; Myprotein states that its Lean bar is not suitable for vegetarians. | I need a bar whose current label fits my dietary requirements, particularly if I am bringing it into a shared workplace. |
| Sweeteners | Read the ingredients and any manufacturer warning, especially if buying a multipack for regular snacks. PhD warns that excessive consumption of its Smart Bar may cause laxative effects. | Before keeping several bars at my desk, I want to know which sweeteners they contain and whether the pack carries a warning relevant to me. |
What is easy to overlook?
-
Equating low sugar with fewer calories
Barebells lists 203 kcal for its 55 g Salty Peanut bar and says its bars are not low- or reduced-calorie foods. PhD lists 250 kcal for a 64 g Choc Brownie Smart Bar.
Compare kcal for one complete bar before weighing up sugar and protein figures.
-
Assuming every flavour has the same nutrition
Myprotein says the nutrition information for its Lean Protein Bar may vary by flavour. The Cookie Dough figures should not be applied to a different variety.
Check the chosen flavour’s portion size and nutrition panel before ordering a multipack.
-
Overlooking sweetener warnings
A low-sugar bar may contain sweeteners. PhD’s Smart Bar information warns that excessive consumption may cause laxative effects.
Read the ingredients and warnings on the selected pack before making it a regular desk snack.
-
Assuming a bar suits everyone at work
Ingredients and precautionary allergen statements differ between bars. The Food Standards Agency explains that precautionary wording communicates possible unintended allergen presence.
Check the current wrapper, including ‘may contain’ wording, rather than relying on the flavour name when choosing or sharing a bar.

Common questions
How can I compare protein bars for a lower-calorie office snack?
Compare kcal for the entire bar you plan to eat, then look at protein and other details that matter to you. Myprotein UK lists 152 kcal for its 45 g Lean Cookie Dough bar and Tesco lists 159 kcal for a 44 g TREK Choc Caramel bar; Barebells lists 203 kcal for its 55 g Salty Peanut bar. A low-sugar claim is not a substitute for the calorie figure.
Should I choose the bar with the most protein?
Not on that figure alone: compare protein and calories for the same whole-bar portion. Myprotein UK lists 18 g protein at 152 kcal for its 45 g Lean Cookie Dough bar, while PhD lists 21 g protein at 250 kcal for its 64 g Choc Brownie Smart Bar. The portion you want for an office snack may make the difference.
Which of these examples is marked suitable for vegans?
Tesco marks TREK High Protein Choc Caramel suitable for vegans and lists 12 g protein per 44 g bar. Check the current wrapper as well: its listing includes precautionary allergen wording for cereals containing gluten, nuts, milk and sesame.
Do I need to check the wrapper if I have a food allergy?
Yes. Check both ingredients and precautionary wording on the current bar: the Food Standards Agency explains that ‘may contain’ labelling communicates possible unintended allergen presence. Tesco also advises reading the physical label because ingredients and allergen information can change when foods are reformulated.
Why check sweeteners before buying a multipack?
The ingredients and any consumption warning matter if you plan to eat the bars regularly. PhD warns that excessive consumption of its Smart Bar may cause laxative effects; check the warning on the exact pack rather than judging it by its low-sugar description.
