The Ultimate Low-Carb Guide to M&S Food (2026)

97% British pork, zero carbohydrates. There are no wheat rusk fillers because there is virtually no room for them. This is the best low-carb sausage available in any mainstream UK supermarket — nothing else at this carb count and meat percentage exists on the high street.

The premium Collection tier. Still exceptional at 0.6g carbs per 100g. A meaningful step up from the Asda Extra Special (2.2g) or Tesco Finest equivalents.

The standard tier. Still well within low-carb parameters and significantly cleaner than most budget alternatives. Free-range British pork.

RSPCA Assured, Better Chicken Commitment compliant, slower-growing Hubbard breed with 20% more space and natural daylight. At £1.50 for 600g this competes directly with standard intensively farmed chicken at budget supermarkets. An extraordinary price for this welfare standard.

750g of high-welfare wings for £1.65. One of the best-value items in the entire store for a low-carb shopper. Season with a dry rub, roast at high heat, and you have the best wings outside of a restaurant.

100% traceable to individual British farm and animal — M&S is the only UK supermarket that guarantees this. 21-day matured. Zero effective carbohydrates.

Choose the 12% or 20% fat variant over the 5% lean mince for a low-carb diet — you need the fat for energy and satiety. 100% British traceable beef.

Streaky bacon is preferable to back bacon on keto — higher fat-to-protein ratio. Just 0.4g of carbs per 100g, minimal curing sugars used.

Sourced from traditional Italian and Spanish producers using protracted air-drying rather than accelerated industrial curing with dextrose. The result is a genuinely clean ingredient list at 0.3g carbs per 100g. Note: typically only available in larger M&S Foodhall stores, not Simply Food outlets.

The premium tier platter. 0.7g carbs per 100g. Pairs with the aged cheeses below for a zero-prep low-carb dinner that feels genuinely luxurious.

Excellent everyday value. 550g block at £4.25 — competitive with Tesco and Sainsbury's own-brand. Prolonged maturation has consumed virtually all residual lactose, hence the near-zero carb count.

Made at the Davidstow Creamery in Cornwall, aged three years. The calcium crystals you can feel are a sign of proper aging and near-zero lactose. An excellent treat-tier cheese with the same zero-carb profile as standard cheddar.

0.1g of carbs per 100g. High fat, soft, and genuinely French. Perfect with the charcuterie selection above.

Genuinely strained Greek yogurt at 4.0g carbs per 100g. Always buy plain — the vanilla variant contains 9.2g carbs per 100g due to added sweeteners. If M&S only has the vanilla in stock, skip it.

1.6g carbs per 100ml. The foundational keto cooking liquid for sauces, coffee, and desserts.

2.7g carbs per 100g. Superior to cream for finishing savoury sauces — the cultured acidity resists splitting under heat.

Authentic blend of cow's, sheep's, and goat's milk from Cyprus. 1.2g carbs per 100g. Excellent structural cheese for grilling, frying, or adding to salads.

0.8g carbs per 100g. Produced for M&S by the Roussas family dairy in Greece. Crumble into salads or baked egg dishes.

M&S was the first major UK retailer to commit to 100% free-range eggs across its entire supply chain. £3.30 for 12 is competitive with mid-market supermarkets. The deep-orange Oakham Gold yolks are particularly striking if you can find them.

Cold-smoked over oak without heavy sugar brines. 1.9g carbs per 100g. An excellent weekend breakfast or salad addition. 140g dressed pack also available at £7.00.

0.4g carbs per 100g, preserved in olive oil rather than sunflower oil. The premium tinned fish option. Avoid the sardines in tomato sauce — the tomato sauce pushes carbs to 2.4g per 100g.

1.3g carbs per 100g. Rich in omega-3 and preserved in olive oil. A step up from budget-tier mackerel in brine.

Effectively zero carbohydrates alongside 86.6g of protein per 100g. The ultimate low-carb crisp replacement. Fridge-free, satisfying crunch, no guilt.

Effectively zero carbs. M&S stocks a wide range of marinated olives — all are excellent low-carb snacking options.

24.6g per 100g sounds high, but nobody eats 100g of 85% dark chocolate. Two squares (20g) delivers just 4.9g of carbs with a complex, intense flavour profile. A luxury treat that fits easily into a tracked low-carb day.

6.6g carbs per 100g. A clean roasted nut mix. Avoid the natural mixed nuts (13.8g/100g) and the chopped mixed nuts (10.4g/100g) — the roasted and salted Collection range is the best macro profile here.

6.2g carbs per 100g. A traditional low-carb deli staple. Important: avoid the Collection Smooth Duck and Orange Pâté — the orange jelly cap and added sugar push it to 11.1g carbs per 100g.

The standout low-carb product in the entire Plant Kitchen range. 1.2g carbs per 100g and 12.6g protein. Made from organic soybeans set with Nigari salt — no starchy binders. Everything else in Plant Kitchen needs label checking, as potato starch and rice flour are common.

One of the only genuinely low-carb ready meals in mainstream UK grocery retail. Courgette noodles replace wheat pasta entirely, delivering just 1.8g carbs per 100g and 6.7g for the whole pack. Availability can be patchy — check Ocado if not in-store.

Cauliflower rice replaces standard rice. Originally designed for people on GLP-1 weight-loss medications (Mounjaro, Wegovy) who need maximum nutrition from minimal calories — but the macros work equally well for low-carb eating. 4.0g carbs per 100g is reasonable for a complete meal.
