Snackers comparing fat
If you want a bar after dinner but are watching fat intake, compare total fat and saturates both per 100g and per bar. A low-sugar claim answers a different question.
Who is this choice for?
The right bar depends on whether fat, protein per portion or the ingredients on the exact pack matter most for your late-night snack.
Shoppers choosing by protein per bar
If the protein amount is central to your choice, check it alongside portion size and fat. The named bars range from 40g to 64g, so per-bar figures alone are not like-for-like comparisons.
People checking ingredients closely
If allergens or sweeteners affect what you can choose, read the label for the exact flavour. Milk, peanuts, soy, wheat and trace-allergen statements differ between the products discussed here.
What should you compare?
Start with fat per 100g to compare bars on the same weight basis, then check what the whole bar contributes to your snack.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Compare fat per 100g, then per bar. Myprotein lists 8.6g per 100g and 3.4g per 40g Lean Layered White Chocolate & Raspberry bar; Tesco lists 8.4g per 60g Grenade Peanut Nutter bar, equivalent to 14g per 100g. The NHS low-fat guide is 3g or less per 100g. | I’m looking for a lower-fat choice, rather than assuming that a high-protein or low-sugar label means low fat. |
| Portion and saturates | Read the serving weight, fat and saturates together. Myprotein lists 1.4g saturates per 40g Lean Layered bar; Tesco lists 3.3g per 60g Grenade Peanut Nutter bar. Compare per 100g when bar sizes differ. | For a snack before bed, I want to know what I’ll get from the portion I actually eat. |
| Protein and energy | Check protein and kcal per bar as well as its weight. Myprotein lists 15g protein and 138 kcal per 40g Lean Layered bar; Tesco lists 21g and 214 kcal per 60g Grenade Peanut Nutter bar. | I’d like a particular amount of protein without overlooking how much larger another bar is. |
| Ingredients | Check the exact flavour’s allergens, trace statements and any excessive-consumption warning. The Tesco Grenade Peanut Nutter listing names milk, peanuts and soy; Barebells lists wheat and soy for Vegan Fudge Brownie and warns that excessive consumption may have laxative effects. | Before choosing a late-night bar, I need its ingredients and warnings to work for me; a vegan label alone does not settle allergen questions. |
Common buying mistakes
-
Reading “reduced fat” as “low fat”
A relative comparison is not the same as the NHS low-fat guide of 3g or less per 100g. Myprotein compares its Lean Layered bars with a stated typical protein-bar average, while its White Chocolate & Raspberry variant lists 8.6g fat per 100g.
Check what the claim is compared with, then read fat per 100g and per bar.
-
Comparing protein without comparing portions
A larger bar can have a higher per-bar protein figure while also contributing more fat and energy. Myprotein lists 15g protein, 3.4g fat and 138 kcal for its 40g Lean Layered variant; Tesco lists 21g protein, 8.4g fat and 214 kcal for the 60g Grenade Peanut Nutter bar.
Use per-100g figures for the product comparison and per-bar figures for the portion you intend to eat.
-
Relying on a range name for allergen information
Ingredients and trace statements need checking for the particular product. Barebells Vegan Fudge Brownie lists wheat and soy and says it may contain milk, peanuts, tree nuts and sesame.
Read the current pack for your chosen flavour rather than applying another bar’s label to it.
-
Overlooking excessive-consumption warnings
PhD and Barebells product information warns that excessive consumption may have laxative effects. That warning matters if you are considering more than one bar as a late-night snack.
Check the serving information and warning on the bar you choose, particularly if you know its sweeteners do not agree with you.
Relevant product ranges
These references concern named bars and variants, not every product made by each brand or every bar sold on Joybuy.
Myprotein
Lean Layered offers a smaller, 40g bar for shoppers comparing fat per 100g and per portion.
- Myprotein lists 15g protein, 3.4g fat and 138 kcal for White Chocolate & Raspberry.
- Its listed 8.6g fat per 100g is above the NHS low-fat guide of 3g or less per 100g.
Grenade
Carb Killa Peanut Nutter is a 60g bar to consider when protein per bar matters more than choosing the lower-fat example above.
- Tesco lists 21g protein and 1.4g sugars per 60g Peanut Nutter bar.
- The same listing gives 8.4g fat and 3.3g saturates per bar and names milk, peanuts and soy as ingredients.
PhD
The listed full-size Smart Bar variants are 64g bars for shoppers comparing protein and portion size.
- PhD lists 21–22g protein per 64g bar across those variants.
- PhD lists 8.5–9.2g fat per bar across those variants and warns that excessive consumption may cause laxative effects; check the chosen flavour.
Barebells
The Salty Peanut and Vegan Fudge Brownie bars provide different ingredient options, but neither is the lower-fat example in this comparison.
- Barebells lists 20g protein per 55g Salty Peanut bar and 15g per 55g Vegan Fudge Brownie bar.
- It lists 8.2g and 9.0g fat per bar respectively. Vegan Fudge Brownie contains wheat and soy and carries a may-contain milk statement.
Protein bars on Joybuy
These Grenade bars are options to compare if you want a protein-bar snack. Their pack sizes and flavours are identifiable here, but do not use the nutritional figures for the different Grenade Peanut Nutter listing above as figures for these Joybuy products; check each chosen flavour’s pack for fat per 100g and per bar.

Grenade Soft Core Double Chocolate, 12 × 50g
A 50g-bar option for a chocolate-flavoured snack. Check the Double Chocolate pack’s fat per 100g and per bar before choosing it for a lower-fat priority.
No image available
Grenade Soft Core Golden Caramel, 12 × 50g
Another 50g-bar option, in Golden Caramel flavour. Compare its own nutrition panel with Double Chocolate rather than assuming the flavours have identical fat values.
No image available
Grenade Soft Core Peanut Butter, 12 × 50g
This Peanut Butter variant comes as 50g bars. Check its own fat figures and allergen statement; figures for Grenade Carb Killa Peanut Nutter do not identify this Soft Core bar.
No image available
Grenade Peanut Butter, 12 × 60g
The stated 60g bar is larger than the Soft Core Peanut Butter bar above. Compare the nutrition and allergen information for this exact pack before treating the two peanut-flavoured products as equivalent.
No image available
Grenade Oreo Flavour, 4 × 60g
A four-pack of 60g Oreo Flavour bars. For a midnight snack chosen on fat content, compare this flavour’s per-100g figure and the amount in one bar with the other options.
Questions about protein bars
Does low sugar mean a protein bar is lower in fat?
No. Fat and sugar are separate figures on the nutrition label. Tesco lists 1.4g sugars but 8.4g fat per 60g Grenade Peanut Nutter bar, so check both values for the bar you are considering.
Does a bar with reduced fat count as low fat?
Not necessarily. The NHS food-label guide defines low fat as 3g or less per 100g. Myprotein lists 8.6g fat per 100g for Lean Layered White Chocolate & Raspberry, despite comparing the range with a stated typical protein-bar average.
Is a vegan protein bar suitable if I avoid milk?
Check the exact product’s allergen statement rather than relying on “vegan” alone. Barebells labels Vegan Fudge Brownie as vegan, but its product information says it may contain milk; it also lists wheat and soy.
What should I do with an excessive-consumption warning?
Read it alongside the bar’s serving information, especially if you might eat more than one. PhD and Barebells warn that excessive consumption of their listed bars may have laxative effects; check the warning on your chosen flavour.
