The 30 Best Keto Foods at Tesco

The ketogenic diet relies on low-carb, high-fat foods to shift metabolism into ketosis. Tesco, like most UK supermarkets, now stocks everything needed for keto without specialist shops. This list focuses on affordable staples available year-round.

Fresh proteins

Tesco’s meat counter offers excellent value. Look for:

British beef mince (20% fat) at £4.50/kg
Whole chickens (£3.50-£5 depending on size)
Pork shoulder joints (£6/kg)
Lamb leg steaks (seasonal, £8-12/kg)

Their Finest range includes dry-aged steaks and organic options. Frozen seafood like salmon fillets (£7/kg) and prawns (£8/kg) provide convenient protein sources. Eggs remain one of the most cost-effective keto foods at £1.80 for 15 free-range.

Dairy and fats

Full-fat dairy supports ketosis:

Cathedral City mature cheddar (£3.50/400g)
Double cream (300ml for £1.25)
Unsalted butter (£1.80/250g)
Greek yoghurt (5% fat, £1.50/500g)

Tesco’s own-brand coconut milk (60p/can) and extra virgin olive oil (£4/litre) are pantry essentials. Their Plant Chef range includes almond milk (£1.30/litre) for those avoiding dairy.

Low-carb vegetables

Seasonal UK produce offers the best value:

Cauliflower (80p/head in summer)
Brussels sprouts (£1.50/500g in winter)
Spinach (£1/200g)
Aubergines (£1 each)

Frozen mixed peppers (£1.25/750g) and broccoli florets (£1/1kg) provide year-round options. Mushrooms (80p/300g) work well in omelettes and stir-fries.

What this means in practice

Building a keto shopping list at Tesco costs roughly £40-£50 weekly for one person. Focus on the perimeter aisles where fresh foods live. The middle aisles contain most processed carbs, though you’ll find sugar-free condiments and electrolyte supplements there.

Tesco’s meal deals don’t suit keto, but their £3 salad boxes (without croutons) make convenient lunches. In autumn, look for reduced pumpkins – their flesh is lower carb than most squashes.

Pantry staples

Stock these for keto cooking:

Almond flour (£3/200g)
Erythritol sweetener (£4/250g)
Coconut flour (£2.50/200g)
Chia seeds (£2.50/150g)

Canned fish like sardines (90p/tin) and tuna (£1/tin) provide emergency protein. Tesco’s nuts and seeds section includes pecans (£3/200g) and flaxseeds (£1.50/150g).

Frequently asked questions

Is Tesco’s keto range good?

Tesco doesn’t label foods as keto, but their standard range includes everything needed. Some products like carb-free jelly (60p/packet) and protein bars (£1.50 each) can fit occasionally.

What’s the cheapest keto food at Tesco?

Eggs, cabbage, and chicken thighs offer the best value per gram of protein. Frozen vegetables often cost less than fresh with similar nutrition.

Can I do keto on a Tesco budget?

Yes. Prioritising own-brand products and buying whole cuts of meat keeps costs down. A weekly shop for one person averages £45-£55, comparable to standard eating.

The bottom line

Tesco stocks all 30 essential keto foods without premium pricing. Focus on fresh proteins, seasonal vegetables, and full-fat dairy while avoiding processed carbs. Meal planning prevents waste – batch cook mince dishes and roast vegetables to last several days. If you’d rather not do the macro maths yourself, the Keto Dieting app does it for you on Google Play and the App Store.
