Finding healthy meals under £1 per serving in the UK can feel impossible when starting a fitness journey. This guide breaks down how to hit your protein targets affordably with supermarket staples and clear meal planning. You’ll learn exact cost-per-gram protein sources, common mistakes to avoid, and a step-by-step weekly budget meal plan. Save money while eating well and progressing towards your fitness goals with practical, UK-specific advice.
Why Protein Is the Hardest Macro to Hit on a Budget
Protein generally costs more per calorie than carbohydrates or fats, making it the most expensive macro to prioritise when dieting or building muscle on a budget. For instance, a 500g pack of chicken breast at Tesco might cost around £3.50 but provides roughly 110g of protein, while 1kg of pasta costs about £1 and offers minimal protein (around 10g per 100g uncooked). This disparity means that unless you focus on affordable protein sources, your food costs will rise quickly.
The NHS recommends adults aim for around 0.75g protein per kg body weight daily, but this can increase to 1.2–1.6g/kg for those doing resistance training or aiming to lose fat while maintaining muscle. For a 70kg person, that’s 84–112g of protein per day. Meeting these numbers on a budget requires prioritising foods with high protein density and low cost per gram. Understanding which foods deliver the best protein bang for your buck is crucial before building meals around them.
The Cheapest High-Protein Foods in UK Supermarkets Right Now
The British Nutrition Foundation lists multiple protein sources, but prices vary widely. To budget effectively, focus on supermarket staples with the lowest cost per gram of protein. According to a breakdown inspired by the Money Saving Expert cheap food guide, here are some top contenders:
- Dried Red Lentils: Around £0.80 per 500g (uncooked), offering 24g protein per 100g dry. Cooked lentils cost roughly 7p per 20g protein portion.
- Eggs: A pack of 6 at Aldi or Lidl costs roughly £1.10, delivering about 6g protein per egg — around 18p per 10g protein.
- Chicken Thighs (skinless): £2.50 for 500g, providing approximately 20g protein per 100g. Cost per 20g protein is about 25p.
- Canned Tuna in Water: Around £1 per 160g tin, offering 35g protein per tin, equating to roughly 29p per 10g protein.
- Frozen Edam Cheese: Priced at £2.50 for 200g, with approximately 25g protein per 100g. Cost per 10g protein is around 50p. For more on fitness guides, see our guide.
Pulses such as chickpeas and beans also offer good protein for their price and add fibre and micronutrients. Combining these with eggs or canned fish can create varied meals without breaking the bank. Bulk-buying and choosing own-brand or discount supermarkets like Aldi and Lidl further reduce costs while maintaining quality. These figures align with the Money Saving Expert cheap food guide for verified prices.

How to Structure Your Meals Around Budget Protein Sources
Once you’ve identified cheap, high-protein foods, structuring meals properly ensures you hit your daily targets without unnecessary spending or waste.
-
Distribute Protein Evenly Across Meals: Aim for 20–30g protein per meal. For example, 3 eggs at breakfast (18g), 100g cooked lentils at lunch (9g), and 150g chicken thighs at dinner (30g). This steady intake supports muscle synthesis better than skewing protein to one meal.
-
Combine Plant and Animal Proteins: Lentils or beans alone lack some essential amino acids but mixing with eggs or dairy covers all bases. This approach also stretches your budget.
-
Plan for Leftovers and Batch Cooking: Prepare large portions of lentils or chicken to use over 2–3 days. This reduces cooking time and food waste, which can add to hidden costs.
-
Include Fibre and Micronutrients: Pair cheap protein sources with vegetables like frozen spinach or carrots to balance meals. Following the NHS Eatwell Guide helps ensure a balanced diet.
-
Use Simple Seasonings and Cooking Methods: Boiling, baking, or stir-frying with minimal oil keeps costs low and calories controlled.
By following these steps, you can consistently meet protein requirements affordably and without meal fatigue.
Common Mistakes When Eating High-Protein on a Budget
Three frequent errors reduce the effectiveness of budget protein strategies:
-
Relying Too Heavily on Expensive Cuts or Brands: Choosing premium chicken breasts or branded canned fish inflates costs unnecessarily. Opting for thighs, eggs, and own-brand canned fish saves at least 30%.
-
Ignoring Protein Quality and Variety: Eating only one protein source daily can lead to nutrient gaps and meal boredom. Variety supports nutrient intake and adherence.
-
Overlooking Preparation and Storage: Cooking small portions repeatedly wastes time and can lead to throwing away leftovers. Batch cooking and proper storage lower food waste and overall spending.
Avoiding these mistakes saves both money and effort while ensuring you reach recommended protein intakes as outlined by the British Nutrition Foundation.
