Asda Pescatarian Higher-Protein Weekly High Protein Low Calorie Plan — 1,800 kcal
Higher-protein meal planning within a lower-calorie target. This 7-day plan targets 1,800 kcal/day and averages 137g of protein, built around Asda's Just Essentials (formerly Smartprice) for roughly £30–40/week. Meals lean on lower-fat protein — white fish, prawns, egg whites and low-fat dairy — so each meal carries more protein for the calories it costs, leaving room to hit the day's target without relying on volume alone.

Plan Details And Assumptions
Asda Shopping Evidence Notes
These basket notes explain why this plan is shaped around certain ingredients and swaps before you open the shopping list.
Best for larger weekly shops, family-style staples, freezer options and value packs that can be portioned.
Works well for 1800-2500 kcal plans where bigger carbohydrate and protein portions are needed.
Check multipacks and frozen ranges before buying many single fresh items.
Why This Exact Plan Exists
This page is not only a title-and-macros variant. The calorie target, supermarket, diet type, budget and prep style all change the meals, shopping-list assumptions and swaps.
What this plan is for
An Asda high protein low calorie plan at 1,800 calories is useful when someone wants a printable week before shopping, not just a generic diet article.
Shopping Logic
The list favours repeatable UK supermarket staples, grouped by protein, carbs, vegetables, dairy and extras so the basket can be checked before buying.
Practical Swaps
The swap section keeps the page usable if a product is out of stock, too expensive, or not right for the reader's diet.

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
Asda
Asda pages balance budget staples with broader family-friendly ranges and frozen options.
Budget
£30–40/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.
Typically the cheapest of the big four on a like-for-like basket, with a genuinely low economy tier.
Value rangeJust Essentials (formerly Smartprice)
Loyalty pricingAsda Rewards (cashback to a wallet rather than instant discounts)
What Asda is good for here
Just Essentials is usually the lowest-priced option in its category, which suits very cheap weeks.
Good value on rice, pasta, oats and tinned pulses — the backbone of a budget prep plan.
Worth knowing before you shop
Just Essentials lines sell out quickly and availability is inconsistent.
Rewards pays into a wallet rather than reducing the shop at the till, so it will not lower this week's bill.
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 Asda's Just Essentials (formerly Smartprice) 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 extra egg whites (3–4) to a breakfast instead of whole eggs — protein without the extra fat
Use 0% fat Greek yogurt or quark instead of standard yogurt for the same volume, far more protein
Keep tinned tuna, mackerel or sardines in for a fast protein top-up with no cooking
