Snackers comparing fat and portion size
If you expect to eat one bar alongside other movie-night food, its per-bar fat, saturates and energy figures tell you what that portion contains. Check the bar weight before comparing it with another flavour.
Who is choosing a movie-night bar?
Shoppers looking for protein and a dessert-style flavour
Chocolate, caramel and brownie-style bars offer different flavours and textures. Compare protein with fat and energy on the same serving basis rather than choosing on the protein figure alone.
People checking ingredients for themselves or a group
The exact flavour matters when someone avoids milk, soya, wheat, nuts or particular sweeteners. Read the current pack’s ingredients, allergen statements and any consumption warning before sharing.
What should you compare on the label?
Start with the amount in the bar you plan to eat, then use per-100-g values to compare bars of different sizes.
| Priority | What to check | Your needs |
|---|---|---|
| Fat and saturates | Read both figures for the exact flavour per bar. Check fat per 100 g when bar weights differ; a sugar claim does not give you the fat figure. | I’m comparing the fat in the portion I would actually eat, not assuming that “low sugar” also means less fat. |
| Energy and portion | Check kcal per labelled bar and its weight. The cited Myprotein, Barebells, Grenade and PhD variants weigh 40 g, 55 g, 60 g and 64 g respectively, according to Myprotein UK, Barebells UK and Tesco Groceries. | One bar may be my whole snack or something I eat with other food, so the size of that bar matters to my choice. |
| Protein | Compare grams per bar alongside fat, saturates and energy. The cited variants list 15 g or 21 g protein per bar, according to their brand and Tesco Groceries product information. | I’d like to compare protein levels without letting that single figure decide between bars with different portions and ingredients. |
| Ingredients and allergens | Read the current pack’s allergen and precautionary statements for the exact flavour. Check its sweeteners and any excessive-consumption warning. | Before sharing a bar, I need to know whether its ingredients and allergen statements work for everyone eating it. |
Common mistakes to avoid
-
Treating “low sugar” or “reduced fat” as the fat figure
These phrases do not tell you how much fat or saturated fat is in the bar you will eat. Myprotein UK lists 8.6 g fat per 100 g for its cited Lean Layered flavour despite its lower-fat comparison claim.
Read total fat and saturates on the exact flavour’s nutrition panel, both per bar and per 100 g.
-
Comparing bars without noticing their weights
The cited bars range from 40 g to 64 g. A per-bar comparison describes one whole snack, but it also reflects how much product is in each bar.
Use per-bar figures for the portion you intend to eat and per-100-g figures when comparing formulations.
-
Overlooking sweeteners and consumption warnings
Several of the cited variants contain sweeteners and carry warnings that excessive consumption may have a laxative effect.
Check the exact pack’s ingredients and warning, particularly if you are considering more than one bar.
-
Assuming “vegan” means free from other allergens
Barebells UK lists wheat and soya in its cited Vegan Fudge Brownie bar, alongside precautionary statements for other allergens.
Read the current physical pack’s allergen declaration and precautionary wording rather than relying on the product category or flavour name.
Brand and retailer references
Myprotein
Myprotein positions its Lean Layered range as a lower-fat alternative to its standard Layered Bar.
- Myprotein UK lists 3.4 g fat, 1.4 g saturates and 138 kcal per 40 g White Chocolate & Raspberry bar.
- The brand’s fat comparison uses a stated October 2022 reference, not a comparison with every bar currently sold. Myprotein says this variant is not suitable for vegetarians and carries an excessive-consumption warning.
Grenade
The cited Chocolate Chip Salted Caramel bar is a 60 g, confectionery-style option listed by Tesco Groceries.
- Tesco Groceries lists 21 g protein per bar.
- The same listing gives 9.3 g fat and 5.4 g saturates per bar and declares milk and soya, with possible gluten, peanut and nut cross-contact.
PhD
The cited Smart Protein Bar Chocolate Peanut Butter is a 64 g bar with a chocolate-and-peanut-butter flavour.
- Tesco Groceries lists 21 g protein per bar.
- Its listing gives 8.6 g fat, 3.3 g saturates and 245 kcal per bar, and carries an excessive-consumption warning.
Barebells
Barebells offers the cited Vegan Fudge Brownie as a plant-based, 55 g bar.
- Barebells UK lists 15 g protein per bar.
- The cited bar lists 9.0 g fat and 4.1 g saturates. It contains wheat and soya, with precautionary allergen statements that still need checking on the pack.
Quest
Quest’s US Chocolate Brownie product page describes a 60 g protein bar; its figures should not be assumed to describe a UK pack.
- For that US product, Quest Nutrition lists 20 g protein and 6 g fat per bar.
- Check a current UK pack’s formulation, portion and allergen declaration before comparing it with UK-labelled variants.
Tesco
Tesco Groceries lists protein bars from several manufacturers, including the cited PhD and Grenade variants; it is the retailer here, not the maker of those bars.
- Its product listings provide per-bar nutrition and ingredient details for comparing named variants.
- Recipes and labelling can change, so check the physical pack before relying on an online ingredient or allergen statement.

Questions about reduced-fat protein bars
Does “reduced fat” mean a protein bar has little fat?
No. A comparison claim is not the amount in the bar. Myprotein UK lists 8.6 g fat per 100 g for the cited Lean Layered flavour and bases its lower-fat comparison on a stated October 2022 reference. Check the current pack’s per-bar and per-100-g figures for your own comparison.
What matters if I plan to eat one bar during a film?
Compare total fat, saturates, energy and protein per labelled bar first. Then compare per-100-g values if the bars are different sizes; the cited Myprotein, Barebells, Grenade and PhD servings range from 40 g to 64 g.
Is a low-sugar bar necessarily lower in fat?
No. Sugar and fat are separate label figures. The cited Barebells, PhD and Grenade variants list 8.6–9.3 g fat per bar, according to Barebells UK and Tesco Groceries, so check fat and saturates even when sugar is prominent on the pack.
Why do some bars carry an excessive-consumption warning?
Several of the cited bars contain sweeteners and warn that excessive consumption may have a laxative effect. Read the exact pack’s ingredients and warning if you are considering more than one bar.
Can I use an online listing to check allergens?
Use the listing to identify what to check, then read the physical pack before eating or sharing the bar. Tesco Groceries cautions that ingredients and allergen information can change, and the cited flavours have different declared allergens and precautionary statements.
