Cost per gram of protein is the key metric for budget high-protein eating. Tinned tuna provides 24 g of protein for around 60–70p per can — about 3p per gram of protein. Eggs deliver 6 g of protein for under 30p each. Chicken breast provides 31 g per 100 g for around 55–70p per 100 g. These three foods alone can cover most of your protein needs for the week at very low cost, supplemented by Greek yogurt and cottage cheese for variety and additional protein density.

Tips for Success
Stock up on tinned tuna in spring water — buy 8–10 cans at once to have protein available for any meal without needing to cook.
Hard-boil a dozen eggs at the start of the week. They keep in the fridge for five days and are the fastest, cheapest protein snack available.
Chicken breast bought in 1 kg+ packs is significantly cheaper per serving than smaller packs. Batch-cook the whole kilogram on Sunday.
Low-fat cottage cheese is consistently one of the cheapest protein-dense foods in UK supermarkets at around 80–90p per 300 g pot (36 g of protein).
Red lentils (500 g for around 80p) provide both protein and fibre — far more per pound spent than any meat. Add them to soups, curries, and stews to reduce cost without reducing nutrition.
