Plan Details and Assumptions
Aldi Shopping Evidence Notes
These basket notes explain why this plan is shaped around certain ingredients and swaps before you open the shopping list.
- Batch-cook plans suit Aldi well because fewer niche products means fewer swaps when ranges change.
- Use the same protein across lunches or dinners if a pack size is larger than one meal needs.
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 1,800 kcal per day | Moderate targets balance breakfast, lunch, dinner and snacks without extreme restriction. |
| Supermarket | Aldi | Aldi pages lean on own-brand staples, simple proteins, frozen veg and budget-friendly repeats. |
| Budget | £45–75/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 Aldi
A limited-range discounter: fewer lines per category, but consistently among the cheapest UK baskets.
What Aldi is good for here
- Cheap frozen vegetables and fruit, which keep weekly costs stable.
- Own-brand dairy — Greek-style yogurt, cottage cheese, skyr — at discounter prices.
Worth knowing before you shop
- Ranges rotate and stock varies by store, so plan a fallback for any single named product.
- Fewer speciality and free-from lines than the big four, which matters for restrictive diets.
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 Aldi's Everyday Essentials range for rice, pasta, oats and tins — nutritionally identical to standard lines, at the lowest price point in store
- 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
