Sainsbury's Cook-Once Weekly Budget Fat Loss Plan — 1,500 kcal
Budget-conscious fat loss on a tight food budget. This 7-day plan targets 1,500 kcal/day and averages 105g of protein, built around Sainsbury's's Stamford Street Co (consolidated value range since May 2023) for an estimated £35–50/week. Meals are chosen to hold up after a few days in the fridge or freezer — stews, chillies, tray bakes and grain bowls — rather than anything that goes soggy or dries out on reheating.

The One Appliance This Plan Assumes
This is a batch plan built around slow-cooked meals — the kind of cooking a slow cooker does unattended while you are out. A 3.5L bowl suits the portion counts here. If you already own one, you need nothing else for this plan.

Slow cookerBudget-to-mid range
Crock-Pot Slow Cooker, 3.5L
The classic entry-level Crock-Pot: two heat settings, a removable ceramic bowl for easy cleaning, and a size that suits most households cooking 3-5 portions at once.
Best forA standard household batch cooking stews, curries and casseroles
Good to knowNo timer or digital display on this entry model, so you set it and check back manually.
This plan uses repeated weekday bases so the Sunday prep instruction matches the actual meals.
Prepare five portions of Protein Waffles with Greek Yogurt and Berries for quick breakfasts.
Cook and portion five lunches of Chicken and Wholemeal Pasta with Pesto.
Batch cook Red Lentil Dahl with Brown Rice and Lean Beef and Sweet Potato Stew as the main dinner bases, then alternate them Monday to Friday.
Cool everything quickly and get it into the fridge within one to two hours.
Refrigerate only the portions you will eat within two days — freeze the rest straight away, and move each one to the fridge the night before you need it. Freezing the later part of the week is a food-safety step, not a freshness preference.
Mid-market: pricier than Asda or the discounters at list price, but Nectar Prices close much of the gap.

What Sainsbury's is good for here
Reliable fresh produce and fish counters for pescatarian and higher-quality prep.
Strong chilled ready-prepared vegetables, which cut prep time on low-effort plans.
Nectar Prices regularly apply to meat and dairy staples.
Worth knowing before you shop
Without a Nectar card the effective basket cost is meaningfully higher.
The Stamford Street value range has been trimmed, so fewer economy lines than a couple of years ago.
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 Sainsbury's's Stamford Street Co (consolidated value range since May 2023) 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)
Switch to Sainsbury's's value range across the board rather than mid-tier lines
Use frozen chicken breast instead of fresh (saves ~£1.50/week, same protein)
Swap fresh berries for frozen mixed berries (same nutrients, fraction of the cost)
💪 Increase protein
Cook an extra portion of mince or beans into the weekly batch — cheap to add, keeps well
Add tinned beans or lentils to a batch-cooked chilli or curry for extra protein at low cost
Portion cooked chicken thighs into the freezer in 100g bags to add to any meal without extra cooking
🥦 Make it vegetarian
Replace chicken with Quorn fillets or diced firm tofu
Swap beef mince for tinned green lentils or plant-based mince
Use halloumi or feta instead of meat in lunch salads
Substitute eggs or cottage cheese for fish-based meals
