Start with the calories in the whole bar, then compare protein and the ingredients of the exact flavour you would buy. Myprotein lists 152 kcal and 18 g protein for its 45 g Lean Protein Bar, while PhD lists 238 calories and 21 g protein for its Smart Bar; neither figure tells you whether a different flavour or bar meets your dietary requirements. Check allergens and any polyol warning before making a bar a regular tea-break choice.
If a packaged bar needs to fit a personal calorie target, compare the whole-bar figure before choosing by its protein claim. The named Myprotein and PhD examples list 152 kcal and 238 calories per bar respectively, according to the brands.
A bar is easy to take to work, but protein and calories need comparing together. Myprotein lists 18 g protein in its 45 g Lean Protein Bar; Tesco lists 20.6 g in its 60 g Active Chocolate Peanut Caramel bar, alongside a higher whole-bar calorie figure.
Vegetarian or vegan labelling does not answer every allergen question. Check the ingredients and any ‘may contain’ statement for the exact bar and flavour, particularly where milk, soya, wheat, peanuts or tree nuts matter to you.
For a morning tea break, compare the ready-to-eat bar first, rather than judging a pack by its front-of-pack description or a per-100 g figure alone.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per bar | Read the energy figure for one complete bar and note its weight. Myprotein lists 152 kcal per 45 g Lean Protein Bar; Barebells lists 202 kcal per 55 g Vegan Fudge Brownie bar. | I want to know what the whole snack contributes to my own calorie target, not just what its pack calls it. |
| Protein alongside calories | Compare grams of protein and calories for the same serving. Tesco lists 20.6 g protein and 222 kcal per 60 g Active Chocolate Peanut Caramel bar; PhD lists 21 g protein and 238 calories for its Smart Bar. | If protein is my main reason for choosing a bar, I can decide whether a higher calorie figure works for this tea break. |
| Sugars and polyols | Check sugars, ingredients and any excessive-consumption warning on the exact product. Tesco lists 12 g polyols per Active Chocolate Peanut Caramel bar; Myprotein and Barebells also carry laxative-effect warnings for excessive consumption. | A low-sugar claim alone does not tell me the bar’s calories or whether its ingredients suit repeat snacking. |
| Dietary suitability | Read the full ingredients and allergen statements, including ‘may contain’ wording. Myprotein says its Lean Protein Bar is not suitable for vegetarians; Barebells lists wheat and soya in its Vegan Fudge Brownie bar. | Before switching flavours or brands, I need to check the particular pack against my dietary requirements. |
Those descriptions do not give the calories in the whole bar. PhD lists 1 g sugar and 238 calories for its Smart Bar, while Myprotein lists 152 kcal and 18 g protein for its 45 g Lean Protein Bar.
Read energy, protein, sugars and serving size together on the flavour you intend to buy.
Barebells lists wheat and soya in its Vegan Fudge Brownie bar and gives ‘may contain’ warnings for other allergens. A dietary label does not replace an allergen check.
Read the current pack’s ingredients and ‘may contain’ statement whenever you change the bar or flavour.
Myprotein, Grenade and Barebells warn that excessive consumption of the named bars may have laxative effects. Tesco lists 12 g polyols in its Active Chocolate Peanut Caramel bar.
Check the ingredient and nutrition panels if sweeteners or polyols affect your snack choice.
A listing does not establish that the flavour or pack format you want is currently available.
Confirm the exact flavour, pack size and availability on the retailer’s current product page before ordering.
These named bars illustrate different label comparisons; a brand name alone does not establish the nutrition or suitability of every flavour in its range.
Its Lean Protein Bar provides a named example for comparing whole-bar calories with protein.
Its Salted Caramel bar is a chocolate-style option with disclosed protein and sugar figures.
The Smart Bar is relevant when protein per bar matters alongside the calorie figure.
Its Vegan Fudge Brownie bar provides a plant-based-labelled option to assess by the complete bar.
The Chocolate Peanut Caramel bar is a supermarket example with whole-bar nutrition figures.
Quest makes protein bars, but a brand-wide description is not a nutrition panel for a particular UK pack.
These packaged bars and flapjacks are options to consider for a morning tea break. Compare the nutrition and ingredients on the exact pack: the selection includes different bar types and multipack sizes.

For a packaged tea-break bar, compare the calories and protein for one 50 g bar rather than the twelve-bar pack. Check the Double Chocolate ingredients and any polyol or allergen warning on the pack.

This four-bar pack offers a nut-bar format for taking one bar to a tea break. Compare nutrition per 40 g bar with larger protein bars, and read the nut and other allergen statements before choosing it.

If protein is your main reason for considering a tea-break bar, compare the nutrition for one 60 g Oreo Flavour bar, including its calories, rather than relying on the low-sugar wording. Check its allergen and polyol information too.

Consider this nut-bar format if you prefer it for a packaged tea break. Read the calories and protein per 42 g bar before comparing it with other protein-labelled products, and check the nut allergen statement.
No image available
A flapjack is another packaged option for a morning break, but its name does not establish that it meets a calorie or protein target. Compare the figures for one 50 g flapjack and check the exact pack’s dietary and allergen labelling.
Compare the calories in the entire bar with your own target, then look at its protein and portion size. For context rather than a universal cutoff, Myprotein lists 152 kcal for a 45 g Lean Protein Bar, while PhD lists 238 calories for its featured Smart Bar.
No: the two figures measure different things. PhD lists 1 g sugar and 238 calories for its Smart Bar; Myprotein lists 1.2 g sugars and 152 kcal for its 45 g Lean Protein Bar. Read energy per bar as well as sugars.
Read the full ingredients and ‘may contain’ statement on the exact flavour and pack before choosing it. For example, Barebells lists wheat and soya in its Vegan Fudge Brownie bar; vegan labelling does not make that bar free from those allergens.
Myprotein, Grenade and Barebells warn that excessive consumption of their named products may have laxative effects. If you are considering bars regularly, check the chosen product’s ingredients, polyol information and pack warning rather than assuming all low-sugar recipes are alike.
