For a lighter night-shift snack, compare the calories in the complete bar before weighing up protein, ingredients and portion size. In the cited UK product listings, Tesco Groceries lists Fulfil Chocolate Salted Caramel at 204 kcal and 20 g protein per 55 g bar, and Grenade Chocolate Chip Cookie Dough at 212 kcal and 21 g protein per 60 g bar. Those figures describe those specific bars, not every flavour or the Joybuy products below.
A bar is easy to carry when a break is brief or its timing changes. Barking, Havering and Redbridge University Hospitals NHS Trust suggests that smaller snacks or a light meal during breaks may suit shift workers better than one big meal at night.
If you want protein in a snack without choosing a larger bar by accident, compare kcal and protein for the same complete serving. A high-protein or low-sugar description does not tell you the bar’s total calories.
Keep the exact flavour’s ingredient list and allergen information in mind when selecting bars to take to work. Plant-based positioning does not remove the need to check ingredients or calories.
Start with the amount you would eat on one break, then compare the nutrition and ingredient information for that exact bar.
| Priority | What to check | Your needs |
|---|---|---|
| Break-time convenience | Check whether the pack contains individual bars and whether its portion size works for your break. Plan where you will keep it during your shift. | I need something I can take to work and eat during a short break, rather than relying on finding a snack late at night. |
| Calories per bar | Compare kcal for the complete bar and note its weight. Check per 100 g figures separately when comparing different portion sizes; do not use a low-sugar description as a substitute for energy information. | A lighter break snack matters to me, so I want to know the calories in the portion I would actually eat. Tesco Groceries lists 204 kcal for its 55 g Fulfil Chocolate Salted Caramel bar and 212 kcal for its 60 g Grenade Chocolate Chip Cookie Dough bar. |
| Protein per bar | Read protein in grams for the exact flavour alongside its kcal figure. Check the serving size before comparing bars of different weights. | I want to know how much protein the snack provides, but a higher protein figure alone would not settle my choice of bar. |
| Ingredients and suitability | Read the exact pack’s ingredients, allergen and may-contain statements, and any declared sweeteners or polyols. Check a plant-based bar’s label rather than relying on its range name. | Before putting several bars in my work bag, I need to know whether that flavour fits my dietary requirements and ingredient preferences. |
Sugar and total energy are different figures. Tesco Groceries lists 1.5 g sugars and 212 kcal for its 60 g Grenade Chocolate Chip Cookie Dough bar; PhD Nutrition lists 0.6 g sugars and 249 kcal for its 64 g Smart Plant Salted Caramel bar.
Compare kcal for the whole bar first if the size of your snack is the deciding factor, then look at protein and sugar.
A portable bar answers a convenience need, but that alone does not establish what to eat across an entire shift. Barking, Havering and Redbridge University Hospitals NHS Trust suggests considering smaller snacks or a light meal during breaks rather than one big meal at night.
Decide which break the bar is for and plan other food separately, instead of treating the packet as a meal plan.
Bars within a range need not have identical ingredients or warnings. Sweeteners, polyols and declared allergens may also matter to your choice independently of the protein figure.
Read the ingredients and allergen statements on the pack you intend to buy, particularly when changing flavour or choosing a plant-based version.
These ranges and retailer listings provide useful points of comparison; their names alone do not establish the nutrition of an individual flavour.

No. Compare kcal for the complete bar separately from sugars. Tesco Groceries lists 1.5 g sugars and 212 kcal for its 60 g Grenade Chocolate Chip Cookie Dough bar, while PhD Nutrition lists 0.6 g sugars and 249 kcal for its 64 g Smart Plant Salted Caramel bar.
Do not assume one bar serves the same purpose as a meal. Barking, Havering and Redbridge University Hospitals NHS Trust suggests that smaller snacks or a light meal during breaks may be preferable to one big meal at night; plan the rest of your food around your breaks rather than relying on the bar alone.
Read the ingredient list, allergen statement and any may-contain warning on the exact flavour and pack you intend to buy. Check again when changing products or flavours rather than assuming the information applies across a range.
No. Vegan suitability and calories answer different questions. PhD Nutrition lists its Smart Plant Salted Caramel bar at 249 kcal per 64 g bar, so compare its complete-bar figure with any alternative you are considering.
