Hosts planning portions
If you plan to offer one bar at a time during a board game night, the kcal figure for the stated bar is more useful for that serving decision than the per-100 g figure alone.
Who is choosing?
Groups with different dietary needs
Vegan, gluten-free or dairy-free labelling may help narrow the choices. Check the exact pack separately for ingredients and allergen warnings before sharing bars with guests.
Guests looking for a protein bar
If protein is the priority, compare its amount per bar alongside calories and serving size. A protein-focused bar need not be the lower-calorie choice.
What should you check?
Start with the portion guests are likely to eat, then check dietary labels and allergens on each flavour you plan to serve.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per bar | Read kcal and grams per bar on the pack. Use per-100 g values to compare bars of different sizes on the same weight basis. | I'm serving one bar per guest, so I want to compare the calories in the portion each person will eat. |
| Dietary labels | Check vegan, gluten-free or dairy-free declarations for the exact flavour. Read the full nutrition panel as well as front-of-pack claims. | Some guests need a particular type of bar, but I still want to know its kcal per bar. Tesco Groceries lists Nakd Cocoa Delight as vegan, gluten-free and dairy-free at 135 kcal per 35 g bar. |
| Allergens | Read the current ingredients and precautionary allergen statements on every pack. Do not use a vegan or gluten-free label as a substitute for those checks. | Before I put several flavours on the table, I need to know whether any guest must avoid an ingredient or a stated cross-contact risk. |
| Protein and portion size | Compare protein, fibre and kcal for the same stated bar. Check its weight rather than assuming all protein bars are the same size. | If a guest wants a protein-focused snack, I can weigh that against the calorie aim. Nature Valley UK lists around 10 g protein and around 4 g fibre in its 196 kcal Peanut & Chocolate bar. |
Common buying mistakes
-
Comparing only kcal per 100 g
Bars in this comparison have different stated weights, so an equal-weight comparison does not tell you the calories in one whole bar.
Use kcal per bar to plan servings. Check the per-100 g figure when you want to compare products on the same weight basis.
-
Assuming a dietary label settles an allergy question
Tesco Groceries labels Nakd Cocoa Delight vegan, gluten-free and dairy-free, but its product information also lists possible traces of soya, peanuts and other nuts. The ingredients for the same 35 g bar list cashews.
Ask guests about relevant allergens and check the current ingredient and precautionary statements for every flavour before serving it.
-
Choosing a protein bar to minimise calories
The named protein-bar examples have higher stated kcal per bar than the named Graze Oat Boosts examples: Nature Valley UK lists 196 kcal for Peanut & Chocolate, Eat Natural lists 220 kcal for its dark chocolate and peanut bar, and Tesco Groceries lists 230 kcal for TREK Smooth Lemon.
Decide whether the portion's protein content or its calorie figure matters more for this snack table, then compare exact flavours and serving sizes.

Questions about choosing snack bars
Which stated bar has fewer calories among the named Graze and Nakd examples?
Graze Cocoa Vanilla Oat Boosts has the lowest stated figure of those three named products: Tesco Groceries lists 116 kcal per 30 g bar, compared with 122 kcal for Graze Sticky Toffee and 135 kcal for Nakd Cocoa Delight. Those figures do not establish which bar has the fewest calories across the UK market or among the Joybuy products shown above.
Does no added sugar mean a bar has little sugar or fewer calories?
No. Tesco Groceries labels Nakd Cocoa Delight no added sugar while listing 15.9 g sugars and 135 kcal per 35 g bar. Read the sugars and energy figures on the full nutrition panel rather than treating that phrase as a calorie comparison.
What should I check before serving bars to a guest with an allergy?
Check the current ingredient list and precautionary allergen statement for every exact flavour, and avoid a product that lists the guest's allergen or a relevant cross-contact warning. UK government allergen guidance identifies cereals containing gluten, milk, peanuts, soybeans and tree nuts among allergens that must be declared when present as ingredients; a vegan or gluten-free claim does not replace the pack check.
Should I choose a protein bar for a lower-calorie snack table?
Choose by the figures for the bar you intend to serve, not by the word protein. Nature Valley UK lists around 10 g protein and 196 kcal for its Peanut & Chocolate bar, while Tesco Groceries lists 9 g protein and 230 kcal for the TREK Smooth Lemon flapjack. Those named bars suit a protein-focused comparison but have higher stated per-bar calories than the named Graze Oat Boosts examples.
