The best keto, carnivore and low-carb snacks are simple, protein-rich foods that actually deal with hunger. In the UK, good options include beef jerky, pemmican, boiled eggs, cheese, tinned fish, leftover meat and other foods built around meat, fish, eggs and dairy rather than sugar, flour and heavily processed snack ingredients.

You do not need to follow a strict keto or carnivore diet to benefit from these ideas.

You might simply want to reduce added sugar, cut back on refined carbohydrates, eat more protein, choose more whole foods or find savoury alternatives to biscuits, sweets and conventional snack bars.

Finding a snack is easy.

Finding one that is lower in carbohydrate, higher in protein and genuinely satisfying can be much harder.

Supermarket shelves are full of products labelled high-protein, keto, low-carb or healthy. Some are useful. Others are essentially sweets, biscuits or cereal bars with protein powder added.

If you follow a carnivore diet, the choice is narrower and generally centres on animal foods.

If you follow keto or simply eat lower-carb, you have a much wider range of foods available. This guide deliberately focuses on the meat, fish, egg and dairy side because those foods naturally provide many of the highest-protein snack options and fit what we specialise in.

Start with real protein.

This is not intended to be a complete list of every food suitable for a low-carb diet. It is a practical guide to 15 meat-focused, protein-rich snack ideas available in the UK, including portable options for work, travel and busy days.

Who Are These Snacks For?

These ideas can work for several different approaches to eating.

They may be useful if you:

• follow a carnivore diet
• follow a ketogenic diet
• eat generally low-carb
• want to reduce added sugar
• want to eat more protein
• prefer simple, recognisable ingredients
• want savoury alternatives to sweets, biscuits and snack bars
• need practical food for work, the gym or travel

The point is not that everyone needs to follow a named diet.

It is simply that many meat, fish, egg and dairy foods are naturally high in protein, relatively low in carbohydrate and useful when you want something more substantial than a sugary snack.

Keto vs Carnivore vs Low-Carb: What Is the Difference?

Keto, carnivore and low-carb eating overlap, but they are not the same thing.

A ketogenic diet is primarily defined by keeping carbohydrate intake low enough to support nutritional ketosis. Depending on the individual approach, keto may include meat, fish, eggs, dairy, low-carbohydrate vegetables, nuts, seeds, olives and other foods.

A carnivore diet is much more restrictive and is generally built around animal foods.

A low-carb diet is broader still. There is no single universal version, and people may simply choose to reduce foods high in sugar and refined carbohydrate without following keto or carnivore at all.

Because of that difference, a snack can be suitable for low-carb eating without being keto, and suitable for keto without being carnivore.

For this guide, we have deliberately concentrated on animal-based options that fit naturally into carnivore eating and can also work extremely well for people following keto or simply reducing carbohydrate and sugar.

That keeps the list relevant to what we do and avoids pretending this is a complete guide to every possible low-carb food.

What Makes a Good High-Protein, Low-Carb Snack?

We judge a snack by a few practical questions.

Does it contain a meaningful amount of protein?

Will it keep you satisfied?

Is the ingredient list simple?

Is it lower in sugar and refined carbohydrate than the snack it is replacing?

Is it easy to prepare or carry?

Does it fit your own dietary approach and carbohydrate target?

Protein is essential for growth and repair, and foods such as meat, fish, eggs and dairy are established sources of protein.

For many people, protein-rich food is also more satisfying than a sweet snack that is easy to eat quickly and forget about ten minutes later.

This is one reason we prefer a protein-first approach to snacking.

15 Easy Keto, Carnivore and Low-Carb Snacks in the UK

1. Beef Jerky

Beef jerky is one of the easiest high-protein snacks to keep in a bag, desk drawer or cupboard.

Because water is removed during drying, jerky provides concentrated beef in a compact form. It is particularly convenient when you want protein without cooking a full meal.

The important part is the ingredient list.

Some commercial jerky contains added sugar, syrups, starches, flavourings or vegetable oils. If you are eating keto, carnivore or simply lower-carb, check the label rather than assuming every packet is suitable.

Our own Beef Steak Jerky is deliberately simple and contains no added sugar or seed oils.

Learn more in What Is Beef Jerky? History, Ancient Meat Preservation and How It Is Made.

2. Pemmican

Pemmican is a traditional food made by combining dried meat with rendered animal fat.

It is more energy-dense than lean jerky because the animal fat contributes a significant amount of energy.

That makes pemmican particularly useful when you want a compact combination of protein and fat rather than protein alone.

It also has a long history as practical travel food.

Read our full guide: What Is Pemmican? Benefits, Taste and Why It Lasts So Long.

3. Hard-Boiled Eggs

Eggs are inexpensive, widely available throughout the UK and easy to prepare in batches.

Hard-boiled eggs give you protein, fat and useful micronutrients in a naturally low-carbohydrate food.

Keep them refrigerated and take them in an insulated lunch bag when you need food away from home.

A little salt is often all they need.

4. Cheese

Cheddar, Red Leicester, Gouda and other hard cheeses can be convenient low-carbohydrate snacks for people who tolerate dairy.

Cheese combines protein with fat and requires virtually no preparation.

For strict carnivore eaters, dairy is a personal choice rather than a universal rule. People eating keto or generally low-carb may also include it depending on their preferences and carbohydrate target.

Choose according to your own tolerance and goals.

5. Tinned Tuna

Tuna is one of the simplest high-protein foods to keep in a cupboard or desk drawer.

Choose tuna in spring water or brine if you want to avoid unnecessary oils.

Ring-pull tins and tuna pouches are especially useful for work, although they are perhaps better suited to a lunch break than a crowded train.

6. Sardines

Sardines provide protein as well as naturally occurring omega-3 fats and micronutrients.

They are inexpensive, shelf-stable before opening and available in almost every major UK supermarket.

If you are avoiding seed oils, check whether the sardines are packed in sunflower oil and choose spring water, brine or an alternative that suits your diet.

7. Mackerel

Mackerel is another convenient oily fish option.

It is naturally richer in fat than tuna and can therefore feel more substantial.

Plain smoked mackerel can be eaten cold, while tinned mackerel is useful as a cupboard staple.

Again, read flavoured-product labels carefully because sauces can introduce sugar and other ingredients you may not want.

8. Smoked Salmon

Smoked salmon is convenient, protein-rich and requires no cooking.

It is more expensive than eggs or tinned fish, but it can be a useful quick snack when you want something ready to eat from the fridge.

Check the ingredients because curing methods differ between products.

9. Cold Roast Beef

Leftover roast beef is one of the best examples of turning a proper meal into tomorrow’s snack.

Slice it thinly, add salt if needed and keep it refrigerated until you are ready to eat.

It does not need a special keto label, protein powder or marketing claim.

It is simply beef.

10. Leftover Steak

Cold steak is surprisingly practical.

If you cook an extra steak at dinner, slice the remainder and refrigerate it for the following day.

For people who dislike conventional snack foods, this can be more satisfying than trying to imitate crisps, biscuits or bars with low-carbohydrate substitutes.

11. Homemade Burger Patties

Plain beef burger patties are easy to batch-cook and can be eaten hot or cold.

Using minced beef and salt keeps the ingredient list extremely simple.

They work particularly well for people who want a more substantial snack or small meal.

If buying ready-made burgers, check for breadcrumbs, starches, sugar and unnecessary fillers.

12. Meatballs Made Without Breadcrumbs

Homemade meatballs can be prepared from beef, lamb, pork or a mixture of meats.

Traditional recipes often use breadcrumbs, but these are not necessary.

Minced meat, salt and egg can produce a simple low-carb version that also suits many keto and carnivore approaches.

Batch cooking makes them useful for packed lunches and busy days.

13. Roast Chicken

Cold roast chicken is another inexpensive way to turn leftovers into a high-protein snack.

Chicken thighs tend to stay moist when eaten cold and contain more fat than breast.

If you are buying pre-cooked chicken rather than making it yourself, check marinades, coatings and seasoning mixes for sugar, flour and seed oils.

14. Pork Scratchings

Pork scratchings are a familiar UK pub snack and can be very low in carbohydrate.

However, products vary enormously.

Some have very short ingredient lists, while flavoured versions may contain starch, sugar, maltodextrin, flavourings or other additions.

They can fit keto, carnivore or lower-carb eating depending on the ingredients, but we would still treat them as a snack rather than a replacement for high-quality meat, fish or eggs.

15. Plain Greek Yoghurt or Full-Fat Natural Yoghurt

For people who include dairy, plain yoghurt can provide a convenient source of protein.

Greek-style yoghurt is generally higher in protein than ordinary yoghurt, but carbohydrate content varies, so people following keto or a tighter low-carb target should check the nutrition label and portion size.

Choose plain versions rather than fruit-flavoured products with added sugar.

Strict carnivore eaters who avoid fermented dairy can simply leave this option out.

Best Keto, Carnivore and Low-Carb Snacks for Work and Travel

Portability changes everything.

Steak and eggs may be perfect at home, but they are not always practical on a train, in an office or halfway through a long drive.

For unrefrigerated convenience, our preferred options are:

• beef jerky
• pemmican
• unopened tins or pouches of fish
• simple pork scratchings

For a chilled lunch bag:

• boiled eggs
• cheese
• cold beef
• burger patties
• meatballs
• roast chicken
• smoked salmon
• plain yoghurt

Planning ahead matters because hunger makes convenience food much more tempting.

If you travel regularly, our guide to Healthy Travel Snacks covers this in more detail.

What to Check on a Keto, Carnivore or Low-Carb Snack Label

Do not rely only on the words printed on the front of the packet.

Terms such as high-protein, keto-friendly, low-carb, natural and healthy can be useful, but the ingredient list and nutrition panel tell you far more.

We look at:

• protein: is there enough to make the snack worthwhile?
• carbohydrate: does it fit your own approach?
• sugar: has sugar, syrup or another sweetener been added?
• oils: does the product contain sunflower, rapeseed, soybean or other oils you personally prefer to avoid?
• fillers: are starches, breadcrumbs or unnecessary bulking ingredients present?
• portion size: is the impressive nutrition claim based on a realistic serving?

This matters particularly with jerky, flavoured fish, burgers, sausages, scratchings and packaged cheese snacks because recipes vary from one manufacturer to another.

Do You Actually Need to Snack?

Not necessarily.

Some people find that meals built around sufficient protein and satisfying whole foods make constant snacking less appealing.

That is very different from deliberately forcing yourself not to eat when you are genuinely hungry.

A snack is useful when there is a practical gap between meals, when you are travelling, after physical activity or when your normal meal timing has been disrupted.

But if you need something every hour simply to keep hunger under control, it may be worth looking at the meals themselves.

Are you eating enough protein?

Are your meals large enough?

Are most of your calories coming from food that actually satisfies you?

Frequently Asked Questions

What are the best low-carb snacks in the UK?

There are many possible low-carb foods, but if you want protein-rich, meat-focused options, beef jerky, eggs, cold meat, fish, cheese and simple burger patties are practical choices. Always check packaged products because sugar, starch and sauces can increase carbohydrate content.

What are the best carnivore diet snacks in the UK?

Simple animal-based foods are usually the easiest choice. Beef jerky, pemmican, eggs, cold beef, burger patties, chicken, fish and, if you tolerate dairy, cheese are practical options. The best choice depends on whether you need something refrigerated or shelf-stable.

What are the best keto snacks with high protein?

Meat, fish, eggs and some dairy foods provide substantial protein while remaining naturally low in carbohydrate. Jerky, tuna, boiled eggs, cold roast meat, chicken, smoked salmon and Greek yoghurt are convenient examples, but packaged-product carbohydrate levels should always be checked.

What are good snacks if I just want to cut sugar?

You do not need to follow keto or carnivore to choose lower-sugar snacks. Plain meat, fish, eggs and unsweetened dairy can all provide savoury alternatives to biscuits, sweets and sugary snack bars. The simplest approach is to check the ingredient list and choose foods with little or no added sugar.

Are whole-food snacks better than protein bars?

That depends on your needs, but whole foods often have shorter ingredient lists and can provide substantial protein without added sweeteners, coatings or fillers. Protein bars can still be convenient. You can compare the two approaches in Beef Jerky vs Protein Bars.

Is beef jerky keto-friendly?

It can be. Plain beef itself is extremely low in carbohydrate, but many jerky recipes contain added sugar, syrups or sweet marinades. Check both the ingredient list and carbohydrate information before buying.

Is beef jerky carnivore?

Jerky made only from meat, salt and animal-based seasonings can fit naturally into a carnivore diet. Products containing sugar, plant oils, starches or other non-animal ingredients may not fit a strict version of the diet.

Is cheese allowed on a carnivore diet?

Some carnivore eaters include cheese and other dairy foods, while others avoid them. Dairy tolerance varies, so there is no single approach that suits everyone.

What low-carb snacks can I take to work?

Jerky and pemmican are particularly convenient because they are compact and easy to carry. With access to a fridge or insulated lunch bag, boiled eggs, cheese, cold meat, chicken, fish, burger patties and meatballs provide many more options.

What should I check when buying low-carb snacks?

Look beyond the front-of-pack claims. Check carbohydrate and sugar values, protein content, portion size and the ingredient list. Foods marketed as keto or high-protein can still contain added sugar, starches, oils or other ingredients you may prefer to avoid.

Final Thoughts

Low-carb, keto and carnivore snacking does not need to be complicated.

And you do not need to follow a strict named diet to use the same basic ideas.

If you simply want to eat more protein, reduce added sugar or choose more foods with recognisable ingredients, start with foods that have always been high in protein:

Meat.

Fish.

Eggs.

And dairy if it works for you.

For home, leftover steak, boiled eggs, burger patties and fish are difficult to beat.

For work and travel, portability matters more. That is where properly made beef jerky and pemmican become particularly useful.

Most importantly, read labels.

A low-carbohydrate snack does not automatically contain simple ingredients, and a high-protein claim does not necessarily mean the food will be satisfying.

Choose food that fits your diet, your appetite and your real life.
