Aldi Pescatarian High Budget Batch Cook Weight Loss Plan — 1,400 kcal
Anyone aiming for a sustainable calorie deficit. This 7-day plan targets 1,400 kcal/day and averages 71g of protein, built around Aldi's Everyday Essentials for an estimated £25–40/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 Peanut Butter Overnight Oats for quick breakfasts.
Cook and portion five lunches of Mackerel and Brown Rice Salad.
Batch cook Tuna and Sweetcorn Pasta Bake and Mushroom and Pea Brown Rice Risotto 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.
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.
