The ketogenic diet shifts the body’s metabolism toward burning fat for fuel instead of carbohydrates. For UK shoppers, Sainsbury’s offers a wide range of keto-friendly foods at competitive prices. This list focuses on fresh ingredients and pantry staples that fit within a typical 20-50g daily carbohydrate limit.

For dairy, their British unsalted butter costs £1.65 for 250g, while double cream sits at £1.10 for 300ml. Mature cheddar averages £2.50 for 400g. These provide the high-fat requirements of the keto macro ratio.

For snacks, their Taste the Difference pork scratchings (£1.50 for 100g) contain zero carbs. Pecan nuts (£2.50 for 200g) provide healthy fats but measure portions carefully due to carb content.

What This Means in Practice
