Plan Details and Assumptions
Generic UK Supermarket Shopping Evidence Notes
These basket notes explain why this plan is shaped around certain ingredients and swaps before you open the shopping list.
- Use common UK staples first: oats, rice, potatoes, pasta, eggs, tins, frozen vegetables, yogurt and lean protein.
- Keep branded products optional so the plan still works at Tesco, Aldi, Lidl, Asda, Sainsbury's, Morrisons, Iceland, Waitrose, Ocado, M&S or Co-op.
- Check cupboard items before shopping because sauces, oil, spices, oats and rice are often already at home.
The Assumptions Behind This Plan
Every plan is built on four decisions. If one of them does not match your week, that is the part to change - the swaps below cover the common cases.
| Decision | This plan uses | Why it matters |
|---|---|---|
| Calorie target | Built around roughly 2,000 kcal per day | Moderate targets balance breakfast, lunch, dinner and snacks without extreme restriction. |
| Supermarket | Generic UK supermarket | Generic UK pages use widely available supermarket ingredients and average-price assumptions. |
| Budget | £50–80/week estimate | Budget plans keep variety while still prioritising own-brand and batch-friendly ingredients. |
| Prep style | Standard (20–30 min/day) | Standard-prep plans balance variety, fresh meals and realistic weekday cooking. |
Shopping This Plan At Generic UK supermarket
Built from ingredients stocked by every major UK supermarket, using average UK pricing rather than one retailer.
What Generic UK supermarket is good for here
- Ingredients are chosen from staples that most UK supermarkets carry, so the plan should work wherever you shop, though ranges still vary by store.
- Easy to swap to a specific retailer later without changing the meals.
- Costs reflect a mid-market average rather than the cheapest or priciest store.
Worth knowing before you shop
- Shopping entirely at a discounter will usually come in below the estimate; a premium store above it.
- No loyalty-scheme pricing is assumed.
Retailer details checked 2026-07-20. Ranges and loyalty schemes change — the weekly cost estimate above is based on the plan's budget tier, not on live prices at this store.
Swaps & Suggestions
💰 Make it cheaper
- Buy own-brand rolled oats, rice, pasta and tins — nutritionally identical to branded, at any supermarket
- Replace fresh salmon with tinned mackerel or sardines in brine (saves ~£2–3/week)
- Buy dried pulses (lentils, chickpeas, black beans) and cook in bulk rather than tinned — cheaper per portion
- Swap fresh berries for frozen mixed berries (same nutrients, fraction of the cost)
- Keep tinned tuna, mackerel or sardines in for a fast protein top-up with no cooking
💪 Increase protein
- Add an extra tin of fish (mackerel, sardines, tuna) rather than reaching for a protein bar
- Use extra eggs or cottage cheese as a whole-food protein top-up between meals
- Swap a processed snack for a handful of nuts and a boiled egg to keep protein whole-food
