The M&S & Ocado Low-Carb Food Guide (2026)
A guide to low-carb M&S Food products in Foodhalls and online through Ocado, with verified carb counts, practical shopping tips, and products to avoid.
Published Updated
M&S Food is available in M&S Foodhalls and stores, while Ocado is its exclusive online home-delivery partner. Treating them as separate shopping guides would duplicate the same M&S range, so this guide covers both routes: shop in person at M&S or use Ocado for an online grocery order.
M&S tends to sit at the premium end of the market, but some of its meat, dairy and convenience products have useful low-carb profiles. Ocado also sells non-M&S brands; those are outside this guide unless we have separately verified their labels and availability.
The 97% pork sausage with 0g of carbs doesn’t exist anywhere else at a major UK supermarket. The Remarksable Value chicken is priced competitively with discount retailers while being RSPCA Assured and Better Chicken Commitment compliant. The Courgetti ready meal is one of the only genuinely low-carb ready meals in mainstream UK grocery retail.
UK label note: The Carbohydrates figure on UK nutritional labels already shows net carbs — fibre is listed separately. No subtraction needed.
Where to buy: Product links open an Ocado search so you can check current online availability. M&S Foodhall ranges vary by store. We do not publish or verify prices.
Key Takeaways
- M&S Our Best Ever Pork Sausage (97% pork, 0g carbs) is the best low-carb sausage in any UK supermarket — nothing at Tesco, Sainsbury’s, or Asda comes close
- Oakham Gold chicken (legs and wings) is exceptional value for high-welfare poultry and directly competes with budget supermarket pricing
- M&S does not stock a genuine low-carb bread or wrap — LivLife has been delisted and no own-brand replacement exists
- “High Protein” does not mean low-carb in the bakery aisle: M&S High Protein White Rolls contain 38.4g of carbs per 100g
- Marinated “sticky” or “BBQ” meats contain significant hidden sugars — look for spice-rubbed options instead
- Avoid vanilla Greek yogurt (9.2g carbs/100g) — stick to plain full-fat (4.0g)
Meat, Fish and Ready Meals
This is M&S’s strongest category for low-carb shoppers by a significant margin. The sausage range is uniquely clean, the chicken is exceptional value for welfare quality, and the two ready meals below are rare examples of genuinely low-carb convenience food.
A critical warning on marinated and glazed meats: The Peri-Peri Chicken Kebabs (1.7g carbs/100g) are fine. The Sticky BBQ Chicken Wings (4.6–6.8g carbs/100g) are not — the “sticky” and “BBQ” in the name signals sugar-based glazes. Always check the label on anything with a marinade.

The Essential Cheddar, Camembert, and Halloumi are excellent everyday choices. The Cornish Cruncher is worth the premium for a special occasion.
Always buy plain Greek yogurt — the vanilla variant contains 9.2g carbs per 100g versus 4.0g for plain. Same brand, very different macros.

Avoid the natural mixed nuts (13.8g/100g) and the chopped mixed nuts (10.4g/100g). The Collection Roasted and Salted range has the best macro profile.

What M&S doesn’t have: bread
M&S currently has no genuine low-carb bread option. LivLife has been delisted across M&S in 2025–2026. The M&S High Protein White Rolls contain 38.4g of carbohydrates per 100g. The Nutrient Dense Super Seeded Oaty Sliced Bread contains 17.4g per 100g. Neither is suitable for strict low-carb eating.
If you need low-carb bread at M&S, the answer is currently: there isn’t one. Use the almond flour sandwich loaf recipe or source BFree wraps elsewhere.
Sparks loyalty card
The M&S Sparks scheme occasionally delivers 10–20% off fresh meat — worth activating the app before a visit if you’re buying steak or salmon. The free product rewards are frequently baked goods which aren’t relevant here.
Are M&S and Ocado worth it for low-carb shoppers?
For specific things, yes. The sausage range is unusually low in carbohydrate, and the chicken, charcuterie and dairy sections offer plenty of straightforward options. M&S Foodhalls work well for a targeted shop; Ocado makes the same brand practical as part of a wider online grocery order. In either case, re-check the current label because recipes and availability change.
