Asda Pescatarian Weight Loss Plan — 1,800 kcal
Anyone aiming for a sustainable calorie deficit. This 7-day plan targets 1,800 kcal/day and averages 126g of protein, built around Asda's Just Essentials (formerly Smartprice) for an estimated £55–90/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.

Shopping This Plan At Asda
Typically the cheapest of the big four on a like-for-like basket, with a genuinely low economy tier.
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

How much does this weight loss plan cost per week?
This plan is designed for Asda and is estimated at £55–90 per week for one person at typical UK prices, depending on what you already have at home. Asda Rewards (cashback to a wallet rather than instant discounts) can reduce this further.
How much protein does this plan provide per day?
This plan averages 126g 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?
