PCOS Meals on a Budget: A Costed Week Under Common Grocery Prices

Does eating well with PCOS have to cost more?

Not by much: the seven dinners below average £0.85 a serving, using UK own-brand supermarket prices from August 2026. That figure is a snapshot, not a promise — prices move, and a supermarket in Leeds and one in Los Angeles do not charge the same amount for a tin of chickpeas. What travels across a US Walmart, a UK Aldi, an Australian Coles or a Canadian No Frills is the order the ingredients come in, cheapest to priciest: dried lentils and frozen vegetables at the bottom, tinned oily fish and fresh meat further up. Use the ingredient list below and that ranking holds even where the currency and the exact number does not.

A naming note, since it comes up: this condition was renamed polyendocrine metabolic ovarian syndrome (PMOS) in 2026 by global consensus — the food and the biology are unchanged, and PCOS is used throughout because that is what most people still search.

Protein is the nutrient most consistently tied to feeling full after a meal, which is why tinned fish, eggs and lentils are the backbone here rather than an afterthought. The 2023 international guideline recommends any sustainable, general healthy-eating pattern over a named diet, and cost is exactly the kind of constraint that should shape which sustainable pattern you actually pick.

The week, costed

Protein runs from 18 grams to 46 grams a serving across the seven dinners below, and every one costs under £1.10 a serving.

Buy the full list once and it makes 28 dinner portions — seven recipes at four servings each — for about £24 total, or well under £1 a serving on average, before any batching or freezing extras.

Lentil & tomato dahl — serves 4 (vegetarian)

Ingredients: 300g dried red lentils · 1 onion, diced · 2 x 400g tins chopped tomatoes · 2 tsp turmeric, 1 tbsp curry powder, 1 tsp cumin · 700ml water or stock · 200g dried rice, to serve

Method: Combine the lentils, onion, tomatoes, spices and water in a pan. Simmer 25 minutes, stirring occasionally, until the lentils break down into a thick sauce. Serve over rice.

Per serving: ~24g protein, 12g fibre. Cost: ~£0.51.

Tinned mackerel & white bean stew — serves 4

Ingredients: 2 tins mackerel in tomato sauce (~125g each) · 2 x 400g tins cannellini beans, drained · 400g tin chopped tomatoes · 1 onion, diced · 2 garlic cloves · 1 tsp smoked paprika · 4 slices bread, to serve

Method: Soften the onion and garlic in a little oil, add the tomatoes, beans and paprika, and simmer 15 minutes. Break in the mackerel for the final 5 minutes, just to heat through.

Per serving: ~30g protein, 15g fibre — the highest-fibre recipe here. Cost: ~£0.96, the priciest of the seven because tinned oily fish costs more than tinned beans or lentils gram for gram.

Egg & frozen vegetable fried rice — serves 4

Ingredients: 6 eggs · 300g frozen mixed vegetables · 300g dried rice, cooked and cooled · 2 tbsp soy sauce · 2 spring onions, garlic, ginger

Method: Scramble the eggs lightly and set aside. Stir-fry the frozen vegetables from frozen for 5 minutes, add the cold cooked rice and soy sauce, and fry 5 more minutes. Stir the eggs back through.

Per serving: ~18g protein, 6g fibre. Cost: ~£0.56 — one of the cheapest here, and a genuine use for rice you over-cooked earlier in the week.

Tinned tuna & chickpea salad — serves 4 (no-cook)

Ingredients: 3 x 145g tins tuna in spring water, drained · 2 x 400g tins chickpeas, drained · 200g frozen sweetcorn, defrosted · 1 red onion, finely diced · juice of 1 lemon · 2 tbsp olive oil · parsley

Method: Combine everything in a bowl and dress with the lemon juice and oil. Rest 10 minutes before serving so the onion softens slightly.

Per serving: ~44g protein, 12g fibre — the highest-protein recipe here, with no cooking required. Cost: ~£1.04.

Frozen fish & frozen vegetable traybake — serves 4

Ingredients: 4 frozen white fish fillets (~125g each), thawed · 500g frozen mixed vegetables or broccoli · 800g potatoes, cubed · 2 tbsp olive oil · lemon, herbs, salt

Method: Toss the potatoes in oil and roast at 200°C for 20 minutes. Add the frozen vegetables and fish to the tray and cook 15 to 18 more minutes, until the fish flakes.

Per serving: ~30g protein, 9g fibre. Cost: ~£1.06.

Turkey mince & lentil bolognese — serves 4

Ingredients: 500g turkey mince (93% lean) · 150g dried red lentils · 1 onion, 1 carrot, diced · 2 x 400g tins chopped tomatoes · 300g dried pasta · garlic, dried oregano

Method: Brown the mince with the onion, carrot and garlic. Add the lentils, tomatoes and 300ml water, and simmer 25 minutes until the lentils soften. Serve over pasta.

Per serving: ~46g protein, 9g fibre — the lentils bulk the meat out, so 500g of mince stretches to four generous portions. Cost: ~£1.09.

Tinned sardine & white bean toast — serves 4 (no-cook heavy)

Ingredients: 2 tins sardines (~120g each), in tomato sauce or oil · 400g tin cannellini beans, drained · juice of ½ lemon · 8 slices bread · tomato and cucumber, to serve

Method: Mash the beans roughly with the lemon juice. Toast the bread, spread with the mashed beans, and top with the sardines. Serve with the tomato and cucumber.

Per serving: ~25g protein, 10g fibre. Cost: ~£0.70.

The five ingredients doing the real work

Five ingredients — tinned fish, eggs, dried lentils, frozen vegetables and own-brand yoghurt — supply most of the protein and fibre above for well under £0.35 per 10 grams of protein, while a branded ready-to-drink protein shake costs more than double that.

None of this makes eggs or protein shakes poor choices — convenience has real value on a genuinely short morning. It means a week built mostly around lentils, tinned fish, frozen vegetables and yoghurt costs meaningfully less than one leaning on named-brand convenience protein, for the same or more fibre. Beans, lentils and chickpeas specifically improve glycaemic control beyond a generic fibre effect, which is convenient, since they are also the cheapest items on this list. A meta-analysis of 10 randomised trials found lower-glycaemic-index eating improved insulin resistance, waist circumference and cholesterol in PCOS without requiring weight loss — and lentils, beans and frozen vegetables are exactly this kind of lower-GI, high-fibre food, and also the cheapest items in the trolley.

Who this will not work for

None of this works if you have no time at all — seven recipes still add up to roughly 80 minutes of hands-on cooking across a week, even at 10 to 15 minutes each. It assumes a fridge and freezer for batching leftovers; without one, cook smaller quantities more often instead of doubling up. Three of the seven recipes centre tinned fish or beans, so a fish or legume allergy rules those out — the egg-and-vegetable fried rice and the turkey bolognese still work without either. And the figures above assume a stocked pantry already has oil, spices and stock in it; a completely bare kitchen costs more to set up than any single week of meals suggests.

This article costs dinners only. As a rough planning figure, breakfast and lunch built around the same core ingredients — oats, eggs, yoghurt, tinned fish — tend to cost a similar amount per meal, but that has not been separately costed here; check it against your own receipts rather than treating it as fixed. Fibre needs the same treatment: the numbers above get you partway there, not all the way.

Start with one dinner, not seven

One of these seven recipes, cooked in bulk and split into four portions, is a smaller commitment than a full week’s shop. Eight slow cooker recipes and ten air fryer recipes both work from a similar cheap-protein pantry if speed or hands-off cooking matters more than price on a given week. The rest of the diet section has the specifics either way.
