Weekly-shop snack planners comparing fat
If you are buying several bars for the week, compare total and saturated fat on the nutrition panels rather than relying on protein or sugar claims on the front of a pack.
Who is this comparison for?
Shoppers looking for a sweet protein snack
Protein, sugars and fat answer different questions. Checking all three for the exact flavour helps you choose a bar that fits what you want from a snack.
Households checking ingredients and warnings
Before buying a box, read the flavour-specific allergen declaration and any sweetener or polyol warning, particularly if several people will share it.
What should you check first?
Compare the nutrition panels on the same per-100 g basis, then use the per-bar figures and pack details to decide whether a flavour works for your weekly shop.
| Priority | What to check | Your needs |
|---|---|---|
| Total and saturated fat | Compare both figures per 100 g across flavours, then check the amount per bar. Myprotein lists 10 g total fat per 100 g for Layered Triple Chocolate Fudge; Tesco lists 16 g per 100 g for Grenade Chocolate Chip Salted Caramel. | I want to compare bars of different sizes without mistaking a smaller serving for a lower-fat recipe. In the Food Standards Agency and Ipsos tracker, 49% of 611 interviewees surveyed from September to November 2024 said they actively used traffic-light labelling when shopping for food; that measures general label use, not protein-bar preferences. |
| Protein and sugars | Read protein and sugars per bar alongside fat; neither figure substitutes for the fat line. Myprotein lists 20 g protein and 1.9 g sugars per 60 g Triple Chocolate Fudge bar. | If I am choosing a protein snack, I still want to know how its sugar and fat figures compare with another flavour I might buy. |
| Ingredients and warnings | Check the exact flavour’s allergens, sweeteners and polyols. Myprotein and Barebells warn that excessive consumption of the listed bars may have laxative effects. | A box needs to suit the people who will eat it, so I would check the label before buying several of the same flavour. |
| Pack format | Confirm the bar weight, number of bars and flavour on the listing. Do not apply one flavour’s nutrition panel or allergen declaration to another. | For a weekly shop, I want to know how many bars I am getting and whether the nutrition information applies to that exact pack. |
What can make a multipack a poor fit?

Assuming high protein or low sugar means less fat
These describe different parts of a nutrition panel. Myprotein lists 10 g fat per 100 g for Triple Chocolate Fudge, while Tesco lists 16 g per 100 g for Grenade Chocolate Chip Salted Caramel.
Compare total and saturated fat per 100 g, then check the per-bar amounts for the flavour you plan to eat.
-
Buying a box before reading sweetener warnings
Myprotein, Barebells and Grenade product information includes warnings about laxative effects from excessive consumption. Ingredients and warnings can differ between products and flavours.
Read the exact pack’s ingredient list and warning before choosing several bars of one flavour.
-
Overlooking saturated fat and allergens
A protein or sugar claim does not describe saturated fat or establish whether a bar suits someone with a food allergy.
Check the full nutrition panel and allergen declaration each time you switch brand, range or flavour.

Frequently asked questions
Are the compared bars low in fat?
Do not assume so from their protein or sugar descriptions. Myprotein lists 10 g fat per 100 g for Layered Triple Chocolate Fudge, while Tesco lists 16 g per 100 g for Grenade Chocolate Chip Salted Caramel; use the exact flavour’s nutrition panel when making your comparison.
Should I compare protein bars per bar or per 100 g?
Use both: per 100 g makes fat figures comparable across differently sized bars, while per-bar values describe the serving you would eat. The referenced Barebells Banana Dream bar is 55 g, Myprotein Triple Chocolate Fudge and Grenade Chocolate Chip Salted Caramel are 60 g, and PhD Smart Bar examples are 64 g.
Does low sugar mean lower fat?
No. Sugar and fat are separate entries on the nutrition panel. Check total and saturated fat for the exact bar even when its description draws attention to sugar or protein.
What should I check before buying a multipack?
Confirm the flavour, bar size and pack count, then read its nutrition panel, allergens, ingredients and any sweetener or polyol warning. This matters when several people will eat bars from the same box or you plan to have the same flavour repeatedly.
Why do some bars carry a laxative-effect warning?
The Myprotein, Barebells and Grenade product information referenced here warns that excessive consumption may have laxative effects. Read the warning on the exact product before buying a box, rather than assuming all flavours carry the same ingredients or advice.
