Most meal-planning advice online assumes you have either an American grocery store full of branded protein powder, or a personal chef. The version that actually works in the UK is much simpler: pick a UK supermarket, build a weekly shop around four or five protein sources, prep on Sunday, and stop thinking about food for the rest of the week. Total time investment: 90 minutes on a Sunday. Total weekly cost: £35 to £50 for one adult, depending on which supermarket you anchor to.
This page is the unstructured version of what Kira Mei's Nutrition Blueprint prescribes in detail — the supermarket-by-supermarket shopping lists, the four prep templates, and the macro math without the obsession.
The UK supermarket hierarchy for meal prep
Not all UK supermarkets are equal for meal prep, and the difference between a good and a bad one is roughly £10 to £15 a week. The rough hierarchy for protein-prep on a budget:
Tier 1 — Aldi and Lidl. Cheapest fresh chicken breast in the UK (£5.49 per kg), cheapest 0% Greek-style yoghurt (£1.69 per 500g), cheapest tinned tuna and tinned tomatoes. The own-brand protein bars, oats and frozen vegetables are typically half the price of the equivalents at the big four.
Tier 2 — Tesco, Sainsbury's, Morrisons, Asda. Wider range, slightly more expensive on the protein staples, but better for specific items like fresh fish (Tesco's salmon offers are competitive) and meal-prep containers.
Tier 3 — M&S, Waitrose. Convenient for ready-meals if you can't prep, but the protein-per-pound ratio is poor compared to Aldi or Lidl. Skip for meal prep purposes.
The single highest-impact change most UK beginners can make to their food budget is switching their weekly shop to Aldi or Lidl. That change alone usually saves £10 to £15 a week without changing what's on the plate.
The four prep templates
These four templates rotate through your week. Two of them on the high-protein day, two on the moderate-protein day, repeat across the week.
Template 1 — Chicken, rice, veg.
- 200g cooked chicken breast (from 250g raw)
- 75g uncooked basmati rice (220g cooked)
- 150g mixed vegetables (frozen peppers, broccoli, sweetcorn, or fresh stir-fry mix)
- Soy sauce, garlic, lemon, black pepper for seasoning
- Approximate macros: 45g protein, 65g carbs, 6g fat, 510 kcal
Template 2 — Salmon, sweet potato, greens.
- 150g salmon fillet (frozen if budget; Aldi's frozen salmon is £8 for 4 fillets)
- 200g sweet potato, baked
- 100g spinach or kale wilted in olive oil
- Approximate macros: 35g protein, 45g carbs, 18g fat, 480 kcal
Template 3 — Greek yoghurt and oats breakfast.
- 200g 0% Greek-style yoghurt
- 50g rolled oats
- 100g berries (frozen if out of season)
- 1 teaspoon honey
- Approximate macros: 22g protein, 60g carbs, 4g fat, 360 kcal
Template 4 — Tuna pasta lunch.
- 75g uncooked wholemeal pasta (220g cooked)
- 1 tin tuna in spring water, drained
- 100g cherry tomatoes
- 1 tablespoon olive oil
- Approximate macros: 38g protein, 60g carbs, 10g fat, 480 kcal
Two of these as the main meals plus one as breakfast or lunch covers most of a day. The remaining calories come from a snack, a piece of fruit, or — when training the same day — a slightly larger portion of the rice or pasta template.
The Sunday prep routine
The first time you do this it takes 2 hours. By week three it takes 75 minutes. The structure:
- Friday — write the shopping list against the templates you're using next week. Order from Aldi or Lidl online if you have delivery in your area, or shop in person on Saturday morning.
- Sunday, 11am–12:30pm — cook the chicken breast in bulk (oven, 200°C, 25 minutes), cook the rice in bulk (rice cooker or 12-minute boil-and-strain), portion both into containers. Roast the sweet potato. Wash and prep the vegetables.
- Refrigerate — five days of prepped containers ready to grab.
This is not glamorous. It is genuinely repetitive. That is the point — the NHS Eatwell Guide is built on the principle that a sustainable diet is mostly the same foods, eaten consistently, with seasonings doing the work of variety. People who try to eat 21 different meals a week to "keep it interesting" stop prepping by week three.
Calories, macros, and not becoming neurotic
A beginner does not need to weigh every gram of every meal. The templates above are within 50–100 kcal of their stated figures, which is well inside the daily variance that doesn't matter. Two rules of thumb:
- Protein matters most. Aim for roughly 1.6g of protein per kg of bodyweight per day. For an 80 kg adult that's 128g — achievable with two of the templates above plus a breakfast and a snack.
- Total calories matter second. If your goal is fat loss, you need a moderate calorie deficit — typically 400 to 600 kcal a day under maintenance. Read Calorie Deficit Explained for what that actually looks like.
You don't need a fitness app subscription to track this. The NHS BMI calculator gives a rough starting point, and any free calorie tracker (the NHS Weight Loss Plan app is free) does the rest. Track for two weeks until you've calibrated your portions, then stop tracking and just eat the templates.
What an actual weekly Aldi shop looks like
For one adult, training three times a week, eating roughly 2,200 kcal a day:
- 1 kg fresh chicken breast: £5.49
- 500g Greek-style yoghurt × 2: £3.38
- 500g basmati rice: £1.49
- 500g rolled oats: £1.45
- 500g wholemeal pasta: £0.95
- Tinned tuna × 4: £3.20
- Frozen berries 500g: £2.49
- Spinach 500g: £1.29
- Cherry tomatoes 350g: £1.39
- Frozen mixed vegetables 1 kg: £1.69
- Eggs 12-pack: £2.49
- Olive oil 500ml: £3.49 (lasts 3 weeks)
- Bananas × 6: £0.79
- Apples × 6: £1.49
- Sweet potato 1 kg: £1.49
Approximate weekly total: £32.56 for one adult, all macros covered, no supplements required.
