Vegetarian Low-Calorie Swaps Weight Loss Plan — 1,800 kcal
Anyone aiming for a sustainable calorie deficit. This 7-day plan targets 1,800 kcal/day and averages 86g of protein, built from ingredients stocked at any major UK supermarket for an estimated £35–65/week. Every meal already carries at least one lower-calorie swap — egg whites instead of whole eggs, cauliflower rice, extra lean protein instead of extra carbs — to keep calories down without cutting protein.

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 1,800 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 | £35–65/week estimate | Budget plans keep variety while still prioritising own-brand and batch-friendly ingredients. |
| Prep style | Minimal (under 10 min/day) | Minimal-prep plans use more assembly meals, ready-to-eat staples and short cooking steps. |
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
- 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)
- Add a couple of eggs or a portion of cottage cheese as a whole-food protein top-up
- Use 0% fat Greek yogurt or quark in place of standard yogurt — same volume, far more protein
💪 Increase protein
- Use 0% fat Greek yogurt or quark in place of standard yogurt for more protein at a similar calorie cost
- Add a hard-boiled egg or egg white as an afternoon snack instead of a higher-calorie option
- Swap a carb side for extra lean protein when a meal feels short on fullness
Frequently Asked Questions
How much does this weight loss plan cost per week?
This plan is designed for a generic UK supermarket and is estimated at £35–65 per week for one person at typical UK prices, depending on what you already have at home. Buying in bulk and choosing own-brand items can reduce this further.
How much protein does this plan provide per day?
This plan averages 86g of protein per day across the week, based on the meals actually selected — in line with general UK guidance of roughly 0.8–1.6g per kg of bodyweight for active adults.
How is this different from a generic weight loss plan?
Plenty of weight loss plans share the same 1,800 kcal target — the difference here is that each meal already has a lower-calorie substitution built in, rather than leaving that to you.
