The calorie number on a pack tells you less than you'd think. What matters is whether the snack holds you until your next meal — and that comes down to protein, fibre and water.
The short version
- Satisfying beats small. A 60-calorie rice cake leaves you hungry; 150 calories of almonds doesn't. The lower number isn't automatically the better snack.
- Look for protein, fibre or water. These three are what make food filling. Most snacks that disappoint on hunger are missing all three.
- Portion size does most of the work. Single-serve packs and small bags solve the problem that "one more handful" creates.
- Read the per-pack figure, not per 100g. A 30g bag and a 150g bag look identical in the per-100g column.
What actually makes a snack filling
Two snacks with the same calorie count can behave completely differently. A handful of crisps and a handful of almonds might land in the same range, but one leaves you reaching for more within twenty minutes, and the other doesn't. Three things explain most of that difference.
| What it brings | Why it helps | Found in |
|---|---|---|
| Protein | Digests slowly and has the strongest effect on feeling full of any nutrient. | Nuts, seeds, dairy, eggs, pulses, roasted chickpeas |
| Fibre | Adds bulk without much energy and slows how quickly the rest is absorbed. | Wholegrains, fruit, vegetables, popcorn, oats, nuts |
| Water | Fills volume for almost no calories. Why fresh fruit and veg feel more substantial than their numbers suggest. | Fresh fruit, salad vegetables, soup, yoghurt |
The practical version: build a snack from at least one of those three, ideally two. Fruit plus nuts. Popcorn plus seeds. Crackers plus something with protein on them. Almost everything on this page follows that pattern.
A note on counting
Calorie bands are a useful way to browse ideas, which is why they're used below. They're not a target to hit, and tracking every number works for some people and makes eating worse for others. If snacking regularly leaves you preoccupied with numbers, or if you're managing a health condition or making changes to how you eat, a GP or a registered dietitian is a better guide than any shopping page. The NHS Eatwell Guide is a sensible free starting point.
Snack ideas by portion size
Approximate values for typical portions. Actual figures vary by brand and portion, so treat these as a rough map rather than exact numbers.
Around 50 calories — something small
| Snack | What it gives you |
|---|---|
| Cucumber slices with lemon and salt | Water and crunch. Almost nothing else, which is the point. |
| Celery or radish sticks | Fibre and volume, very low energy. |
| A small handful of air-popped popcorn | Wholegrain fibre with real bulk for the calories. |
| Kimchi or pickles | Sharp and savoury — useful when the craving is for flavour rather than food. |
| Herbal tea with lemon | Sometimes the craving is thirst or habit rather than hunger. |
Around 100 calories — a proper snack
| Snack | What it gives you |
|---|---|
| Carrot sticks with hummus | Fibre plus a little protein and fat. Holds better than veg alone. |
| Plain yoghurt or cottage cheese | High protein, high water. One of the most filling options per calorie. |
| A small bag of freeze-dried fruit | Whole fruit with the water removed — fibre and sweetness, no added sugar. |
| Wholegrain crackers | Best with something protein-based on top rather than eaten alone. |
| A square or two of dark chocolate | Intense enough that a small amount registers as a treat. |
| Roasted edamame or chickpeas | Crunchy, savoury, genuinely high in protein and fibre. |
Around 200 calories — a mini meal
| Snack | What it gives you |
|---|---|
| A small handful of almonds or cashews | Protein, fibre and unsaturated fat. The most reliably filling snack there is. |
| Nut and seed trail mix | Same benefits, more variety. Watch the portion — it's easy to keep dipping. |
| Avocado on wholegrain toast | Fibre and fat together. Closer to a light meal than a snack. |
| Oat bar or energy ball | Portable and portion-controlled. Sugar content varies enormously between brands. |
| Nut butter on a rice cake with banana | Turns a rice cake from a disappointment into something that holds. |
Shelf-stable options we stock
We're an online grocer, so what we can ship you is the cupboard half of the list above — nuts, seeds, freeze-dried fruit, oat bars, dried fruit and dark chocolate. Fresh yoghurt, cottage cheese and salad vegetables you'll want from a supermarket. Check each pack for its own nutrition figures, since they vary by portion and variety.
Snacks that travel well and portion easily
Mixed Berry Freeze-Dried
Four berries with the water removed and nothing added. Fibre and real fruit sweetness in a bag small enough that the portion decides itself.
From £10.55Shop
Fruit Crisps Multipack (10)
Ten sealed bags rather than one big pouch — the simplest form of portion control there is. Dragon fruit, mango and jackfruit.
From £13.20Shop
Organic Shelled Almonds
Protein, fibre and unsaturated fat in one ingredient. Higher in calories than most items here and far more filling — which is the trade worth making.
From £4.31Shop
Paprika Roasted Corn
For when the craving is salty and crunchy rather than sweet. Wholegrain corn with a smoky seasoning — a better answer to that urge than crisps.
From £3.43Shop
Montagu Low GI Mix
Nuts, seeds and dried fruit blended for slower energy release. Decant a portion into a small container rather than eating from the bag.
From £7.38Shop
Raw Chocolate Signature Dark
A 61% dark bar. Strong enough that two squares feel like a proper treat, which is the whole trick with chocolate.
From £8.79Shop
Stock the cupboard, not the biscuit tin
Nuts, seeds, dried and freeze-dried fruit, delivered across the UK.
Portion control without counting anything
Most people don't overeat snacks because they chose the wrong food. They overeat because the pack was open and within reach. These habits deal with that directly.
-
Buy single-serve where it matters
Nuts, dried fruit and anything moreish. Multipacks cost a little more per gram and are worth it, because the decision about how much to eat gets made once, in the shop.
-
Decant before you sit down
Put a portion in a bowl and put the bag away. Eating from a large pack while doing something else is the single most reliable way to lose track.
-
Pair rather than pile
Fruit with a few nuts. Crackers with something protein-based. Two components that complement each other satisfy on less than one component eaten repeatedly.
-
Have a drink first
Thirst is easy to mistake for hunger, particularly mid-afternoon. A glass of water costs you nothing and answers the question.
-
Keep the good options at eye level
Whatever's visible and easy to reach gets eaten. Front of the cupboard for the things you actually want to snack on, back of the cupboard for the rest.
Lower-carb options
If you're keeping carbohydrates down, the shape of a good snack changes: protein and fat do the work, and the carbs come from vegetables rather than grains or dried fruit.
- Nuts and seeds — walnuts, almonds, pumpkin seeds, sunflower seeds. Low in carbohydrate, high in fat and fibre.
- Cheese — cubes, sticks or a slice with a few olives. Filling and almost carb-free.
- Eggs — hard-boiled, made ahead, kept in the fridge. Cheap, portable, very high in protein.
- Meat and fish — jerky, tinned fish, cold roast chicken. Check jerky labels, as sugar is common in the marinade.
- Non-starchy vegetables — peppers, cucumber, celery with a dip based on yoghurt, cheese or nut butter.
- Dark chocolate at high cocoa percentages — the higher the cocoa, the lower the sugar. The British Nutrition Foundation explains which sugars actually matter.
Note that dried fruit, however healthy, is concentrated fruit sugar. It's a good snack, but not a low-carb one.
Gluten-free snacks, honestly
Worth being clear about this, because a lot of food writing gets it wrong. A gluten-free diet is not healthier for people who don't need one. It's a medical necessity for people with coeliac disease, and a useful choice for people with a diagnosed sensitivity. For everyone else, removing gluten gives no benefit, and gluten-free versions of processed snacks are often higher in sugar or fat to compensate for texture.
That said, plenty of genuinely good snacks happen to be gluten-free without being processed at all:
- Nuts and seeds, plain or roasted
- Fresh and dried fruit, and freeze-dried fruit
- Plain yoghurt and cheese
- Roasted chickpeas and edamame
- Popcorn and plain rice cakes
- Dark chocolate, checking the label for barley malt
If you're buying for someone with coeliac disease, look for an explicit gluten-free statement rather than reasoning from the ingredients, and check every pack — recipes change. We compared the two categories properly in our guide to gluten-free snacks vs regular snacks.
Reading the label
- Use the per-pack column, not per 100 g. Per 100g lets you compare products; per pack tells you what you're about to eat. Small bags and large pouches look identical in the first column.
- Check the stated portion size. A pack labelled "2 servings" that you'll finish in one sitting means doubling every number on the panel.
- Look at fibre and protein, not just calories. These are the numbers that predict whether you'll be hungry again in half an hour.
- "Light", "diet" and "skinny" aren't regulated the way you'd assume. Turn the pack over rather than trusting the front.
- Watch the sugar on dried fruit and bars. Both can be excellent snacks; both vary hugely between brands. Our snack nutrition guide goes through the panel line by line.
This article is general information about food, not dietary or medical advice. Nutrition figures quoted are typical values for common portions and will differ from any specific product — always check the pack.

Frequently asked questions
What counts as a low-calorie snack?
There's no legal definition, but most people mean something under roughly 200 calories. More useful than the number is what's in it: a snack with protein or fibre will hold you far better than a lower-calorie one made of refined carbohydrate.
Are nuts too high in calories for snacking?
No. Nuts are energy-dense, but their protein, fibre and fat make them unusually filling, so a small handful does more than a larger portion of something lighter. Portion them out rather than eating from the bag.
Is dried fruit a healthy snack?
It's whole fruit with the water removed, so the fibre and nutrients stay and the sugar becomes concentrated. That makes it a good snack in small portions, and an easy one to overeat. It isn't a low-carb option.
Is a gluten-free snack healthier?
Not unless you have coeliac disease or a diagnosed sensitivity. Gluten-free versions of processed snacks are sometimes higher in sugar or fat to make up for texture. Naturally gluten-free whole foods like nuts, fruit and yoghurt are a different matter.
What's the most filling snack for the fewest calories?
Something combining protein with water — plain yoghurt, cottage cheese, or vegetables with a protein-based dip. Air-popped popcorn is the best of the dry options, because fibre gives it real volume.
How do I stop overeating snacks?
Change the packaging rather than your willpower. Buy single-serve bags for the things you find moreish, decant a portion into a bowl before you start, and keep the pack out of reach while you eat.
Do you deliver healthy snacks across the UK?
Yes — we ship UK-wide, with free delivery once your order passes £50. Full details are on our shipping policy page.
