# The cheapest high-protein foods
There's a myth that eating enough protein means a fridge full of premium steak and a shelf of expensive powder. It doesn't. Some of the best dollar-for-gram protein on earth is sitting in the cheapest aisles of the supermarket.
Here's how to hit your protein target without wrecking your grocery budget.
First: you need less than you think
The influencer standard of 250–300g of protein a day is overkill for almost everyone. The evidence-based range for building muscle is 1.6–2.2g per kg of bodyweight per day. For an 80kg person that's roughly 130–175g — and there's little extra benefit above it.
Chasing an absurd number is the single biggest reason protein feels expensive. Set a sane target first.
The dollar-for-gram winners
- Eggs — about 6g of protein each, endlessly versatile, and among the cheapest complete proteins available.
- Canned tuna / fish — roughly 25g a tin, near-zero prep, long shelf life.
- Milk and Greek yoghurt — protein you can drink or spoon; milk is one of the best-value sources going.
- Dried legumes — lentils, chickpeas and beans are dirt cheap in bulk and stack protein with fibre.
- Chicken thighs — cheaper and tastier than breast, and just as useful for hitting your numbers.
How to buy it cheap
The trick isn't just *what* you buy, it's *how*:
- Buy in bulk and freeze. A big bag of frozen chicken or a tray portioned into the freezer costs far less per gram than single-meal packs.
- Shop the basics, not the marketing. "High-protein" branded snacks cost a fortune per gram. Whole foods win every time.
- Cook in batches. Wasted food is wasted money — prep what you'll actually eat.
A sample day under a few dollars
Here's a simple day that lands well over 150g of protein for the price of a coffee:
- 4 eggs (~24g)
- 1 tin of tuna (~25g)
- A large Greek yoghurt (~20g)
- A scoop of oats with milk (~15g)
- Chicken thighs with rice and veg for dinner (~40g)

FAQ
Common questions
What is the cheapest source of protein?
Eggs, canned tuna, milk, Greek yoghurt and dried legumes are consistently the cheapest per gram of protein. Chicken thighs are the best-value fresh meat — cheaper and tastier than breast. Buying in bulk and freezing lowers the cost further.
How much protein do I actually need?
For most people building muscle, 1.6–2.2g per kg of bodyweight per day is the evidence-based range. There's little benefit to going much higher, so chasing 300g a day just makes protein needlessly expensive.
Is cheap protein lower quality?
No. Eggs, dairy, fish and meat are all complete, high-quality proteins regardless of price. Even cheaper plant sources work well when you eat a variety and hit your total. Price has little to do with protein quality.
