Keto does not need to be expensive. These UK-specific supermarket swaps and buying strategies can reduce your keto shopping bill by 30–40% without compromising nutrition.
Chicken breasts → chicken thighs (half the price, more flavour, higher fat). Fillet steak → sirloin or ribeye (better fat content, better price). Salmon fillets → whole salmon (much cheaper per kg). Deli meats → cook your own roast meats.
Branded olive oil → supermarket own-brand EVOO (same quality, 40% cheaper). Specialist nut butters → supermarket almond butter. Organic butter → standard butter (marginal difference for most people).
Buy frozen broccoli, spinach, and cauliflower — identical nutritional profile to fresh at a fraction of the cost. Buy seasonal vegetables (spring greens in April, courgettes in summer) when prices drop.
Nuts and seeds from Costco or online are dramatically cheaper per kg than supermarkets. Buy full-fat double cream in 500ml cartons rather than small sizes. Eggs in 30-packs are significantly cheaper per egg.
Aldi for eggs, dairy, and meat. Costco for nuts, olive oil, and tinned fish. Waitrose/M&S own-brand for specific premium items. Online for supplements. Cook from our budget-friendly keto recipes to maximise every ingredient.
Keto on a budget is absolutely achievable in the UK. Strategic shopping and cooking habits can deliver excellent nutrition for under £35 per week per person.
