The Cheapest Keto Snacks Under £1

The ketogenic diet doesn’t have to break the bank. With some planning, you can find plenty of satisfying snacks that keep you in ketosis for under £1 per serving. The key is focusing on whole foods that are naturally low in carbohydrates and high in healthy fats.

Supermarket Staples Under £1

Most UK supermarkets stock several keto-friendly snacks at budget prices. At Tesco, you can find 200g packs of mature cheddar for £1.75, working out to around 35p per 40g serving. Lidl sells 200g of roasted salted peanuts for £1.29, about 32p per 25g portion. Hard-boiled eggs cost roughly 20p each when you buy them by the dozen.

keto meal prep on a budget can help you save even more. Buying in bulk and portioning snacks yourself typically works out cheaper than pre-packaged options.

What This Means in Practice

During colder months when fresh produce costs more, focus on shelf-stable options like canned fish. A tin of sardines in olive oil costs 85p at Asda and provides both protein and healthy fats. Pair it with some celery sticks (about 10p per stalk) for extra crunch.

For those with limited time, many supermarkets now offer pre-cut vegetables. A 200g pack of cucumber slices costs 60p at Sainsbury’s – portion it into four snacks with some cream cheese for under £1 per serving.

Making Your Own Budget Keto Snacks

Simple homemade options often provide the best value. Bake a batch of easy keto cheese crisps using grated cheddar (about 50p worth per baking tray). Or mix desiccated coconut (35p per 100g at Morrisons) with a little peanut butter for energy bites.

Frequently Asked Questions

Are peanuts keto-friendly?

Peanuts contain about 5g net carbs per 25g serving, so they can fit into a keto diet in moderation. Opt for plain roasted varieties without added sugars or starches.

How can I make keto snacks more filling?

Combine protein with fat for maximum satiety. Try pairing a boiled egg (20p) with a slice of ham (30p) or some olives (50p for 30g at Aldi).

What’s the cheapest source of keto fat?

Vegetable oils provide the most fat per penny, but whole food sources like eggs, cheese, and fatty fish offer better nutrition. A tablespoon of extra virgin olive oil costs about 15p.

The Bottom Line

Eating keto on a budget requires some creativity, but plenty of options exist under £1 per serving. Focus on whole foods, buy in bulk when possible, and consider making your own snacks.
