How to Eat on a Budget While Building Muscle

By Zerxus Team  |  Nutrition

The myth that building muscle requires expensive protein powders, organic chicken breast, and a supplement stack costing hundreds per month needs to die. Building muscle is achievable on almost any food budget — if you know which foods to prioritise. Here is how to eat for muscle growth without spending a fortune.

The Most Cost-Effective High-Protein Foods

Eggs (Approximately $0.25–0.35 per egg)

One of the most nutritionally complete foods available. 6g protein per egg, high bioavailability, rich in vitamins and healthy fats. Buy in bulk (12 or 30 packs) for the lowest price per egg. Scrambled, boiled, poached — the most versatile protein source at the lowest cost.

Tinned Tuna/Sardines ($0.75–1.50 per can, ~25g protein)

Tinned fish is one of the best value protein sources available. Sardines add omega-3 fatty acids and calcium (from the small, edible bones) alongside the protein. Tinned tuna in spring water is slightly cheaper. Both require zero cooking and can be eaten straight from the tin or added to pasta, rice, or salad.

Chicken Thighs ($2–4/lb, ~20g protein per 100g)

Boneless chicken thighs are significantly cheaper than breast while providing similar protein content and substantially more flavour. Batch roasting a tray of thighs once per week provides ready-to-eat protein for days. Frozen chicken thighs are even cheaper — stock up and freeze.

Lentils and Legumes ($0.75–2.00/lb dry, ~9g protein per 100g cooked)

Dry lentils, chickpeas, and black beans are among the cheapest protein sources per gram available. Not complete proteins alone — but combined with rice or other grains, they provide a full amino acid profile. Excellent for supplementing animal protein sources to hit daily targets affordably.

Greek Yoghurt ($3–5 for 16oz, ~10g protein per 100g)

Higher protein per weight than regular yoghurt due to straining. Buy supermarket own-brand rather than premium brands — identical nutritional content at 30–50% lower cost. Excellent as a snack, breakfast base, or post-workout protein source.

Minced Beef / Pork ($3–5/lb, ~20–25g protein per 100g)

5% fat mince is expensive; 20% fat mince is significantly cheaper and still high in protein. Drain excess fat after cooking. Batch cook bolognese, chilli, or meatballs at the start of the week for quick, cheap, protein-dense meals throughout.

Budget Meal Planning Strategy

• Batch cook 2–3 times per week — cooking in bulk reduces cost and prep time
• Buy dry goods in bulk: oats, rice, lentils, pasta — cheaper per serving than pre-packaged equivalents
• Frozen vegetables are nutritionally equivalent to fresh at a fraction of the cost
• Supermarket own-brand dairy, eggs, and tinned fish cost 30–50% less than branded products for identical nutrition
• Plan meals before shopping — reduces impulse purchases and food waste

Frequently Asked Questions

Do I need protein powder to build muscle on a budget?

No. Protein powder is a convenience product, not a necessity. That said, whey protein is often one of the cheapest sources of protein per gram — bulk unflavoured whey can cost less per gram of protein than chicken breast. If struggling to hit protein targets from whole foods, budget whey is a cost-effective option.

Is it possible to build muscle as a vegan on a budget?

Yes — though it requires more planning. Prioritise soy products (tofu, tempeh, edamame — complete proteins), combine grains and legumes, and consider a pea/rice protein blend supplement. Beans, lentils, and chickpeas are extremely cost-effective vegan protein sources.

How much should I budget for food when building muscle?

A muscle-building diet built around eggs, tinned fish, cheaper cuts of meat, legumes, oats, rice, and frozen vegetables can be achieved for $50–80 per week per person in the US (as of 2026). Protein targets of 150–200g/day are achievable at this budget with careful planning.
