High-Protein Snacks You Can Buy in Any UK Supermarket
The best high-protein snacks in a UK supermarket are mostly plain foods, not products with “protein” on the wrapper: Greek-style or skyr yoghurt, cottage cheese, boiled eggs, sliced chicken or turkey, tinned fish, edamame, milk and good-quality jerky. They give you a meaningful amount of protein for the calories, they keep you full, and they cost less than branded bars. The quick test is the label: look for a product where protein is a large share of the calories, and check the sugar line before you trust the front of the pack.
Why snacks are where protein falls through the gaps
Most busy professionals eat a reasonable amount of protein at dinner and very little before it. Breakfast is toast or a pastry, lunch is a sandwich, and the afternoon is biscuits from the meeting room. If you are trying to build muscle, hold onto it while losing fat, or simply stay full until dinner, a snack is the easiest place to add some protein without changing anything else.
How much you need overall depends on your goals and is covered in our guides on protein for fat loss and protein for building muscle. Here the question is narrower: what can you actually pick up on the way to the office or between meetings.
How to read the label in ten seconds
UK packaging gives nutrition per 100g and usually per portion. Three checks are enough:
- Protein per portion. Look at the portion you will actually eat, not per 100g. For a snack, somewhere around 10g or more is a useful amount.
- Protein compared with calories. A rough guide: if the calories are less than about ten times the grams of protein, it is a protein-rich food. 15g of protein for 130 calories is good. 10g of protein for 250 calories is a snack with some protein in it.
- Sugar and saturated fat. The front-of-pack traffic light labels help here. Lots of red is a sign the “protein” is mostly marketing.
The NHS guide to food labels explains the traffic light system and the per-100g thresholds clearly.
The shortlist: what to put in the basket
Exact figures vary by brand and pack size, so check the label. These are the categories that reliably earn their place.
| Snack | Why it works | Watch out for |
|---|---|---|
| Skyr or fat-free Greek-style yoghurt | High protein for few calories, filling, cheap | Flavoured versions can carry a lot of added sugar |
| Cottage cheese | One of the most protein-dense dairy foods | Salt; texture puts some people off |
| Boiled eggs (ready-peeled packs) | Portable, no prep, satisfying | Two eggs is a modest amount of protein on its own |
| Sliced chicken or turkey breast | Very lean, eat straight from the pack | Salt in processed slices; choose plain |
| Tinned tuna or salmon (ring-pull) | Excellent protein for the money; salmon adds oily fish | Needs a fork; not everyone’s idea of an office snack |
| Edamame beans | Plant protein plus fibre, in the frozen or chilled aisle | Lower protein per calorie than dairy or meat |
| Milk or a plain milk drink | Easy to carry, combines protein with fluid | Flavoured milks can be high in sugar |
| Beef jerky or biltong | Very high protein per gram, keeps in a drawer | Salt and price; eat in small amounts |
| Roasted chickpeas | Crunchy alternative to crisps, adds fibre | More carbohydrate than protein |
Combinations that do better than either alone
- Skyr with a handful of berries: protein plus fibre and some sweetness without a sugary flavoured pot.
- Cottage cheese on two rice cakes or oatcakes: a small, proper snack at your desk.
- Two boiled eggs and an apple: a no-fuss pairing from any meal deal fridge.
- Chicken slices with a bag of sugar snap peas or carrot sticks: crunchy, filling, very lean.
- Edamame and a small piece of cheese: a good vegetarian option. Soya yoghurt works similarly.
The “protein” products: worth it or not?
Supermarket shelves now carry protein crisps, protein cookies, protein cereal, protein pancakes and protein water. Some are fine. Many are a standard snack with a little added protein and a higher price.
- Protein bars can be useful in a bag for travel days. Read the label: some are closer to a chocolate bar than a meal. Look for one where protein is high relative to calories and sugar is not leading the ingredients.
- Ready-to-drink protein shakes are convenient after training or on a long day. Not essential, but not harmful for most healthy adults. More in our straight answer on whether you need protein powder.
- Protein crisps and cookies rarely make the cut on the calorie test. Treat them as treats, not as part of the plan.
Keeping it practical at work
The snack you eat is the one within reach when you get hungry. A few habits that make the good options the easy ones:
- Keep jerky, a tin of fish and some oatcakes in your desk drawer.
- Buy yoghurt or cottage cheese in multipacks on Monday and leave them in the office fridge.
- Pick the protein option from the meal deal snack section before you get to the crisps.
- If you train in the evening, a protein snack in the late afternoon makes the session go better and stops you arriving home ravenous. Aim to eat it one to three hours before you train.
If you have kidney disease, are pregnant, have a diagnosed food allergy or are following medical dietary advice, check with your GP or dietitian before making big changes to your protein intake.
Where this fits with training
Snacks are a small lever, but they compound. For clients training with us, nutrition is part of the conversation from the first session: what you eat on training days, how much protein you are really getting, and which changes are realistic around your diary. We use the InBody scanner in the studio to track muscle and fat over time, which shows whether those changes are working. If you want help pulling training and food together, our personal training in Highgate page explains how sessions run, and you can read more about private 1-1 coaching with Artem.
Questions we get asked
What is the cheapest high-protein snack?
Usually own-brand fat-free Greek-style yoghurt, cottage cheese, eggs or tinned tuna. Branded protein products are almost always more expensive per gram of protein.
Are protein bars healthy?
Some are reasonable. Many are high in sugar or sweeteners and calories. Use them for convenience, not as the main source of protein.
How many snacks should I eat a day?
There is no right number. If your meals include enough protein and you are not hungry between them, you may not need any. A snack helps most when there is a long gap.
Are plant-based snacks as good?
They can be. Edamame, tofu bites and some soya yoghurts are good options, though many plant snacks are lower in protein per calorie, so check the label.
