When you're looking to build muscle, burn fat, and boost your metabolism, adding more protein to your diet is a prime resolution.

Now that you're convinced to pack your diet with this magical macro, find out how to do so without breaking the piggy bank. All of our go-to cheap protein sources below cost less than a dollar and provide at least six grams of satiating protein per serving.

Hemp Seeds, 1.5 lb Bag

Hemp seeds

10 g protein per 3 Tbsp

$0.88 per serving

Jazz up your breakfast parfaits and morning oats with a sprinkle of hemp seeds. The subtle nutty flavor and high omega-3 content will help keep you satisfied and satiated, guilt-free. The cannabis-plant-derived seeds are a solid superfood that can be incorporated in almost any diet, providing a vegan source of complete protein and Gamma-linolenic acid (GLA), a fatty acid that's been shown to relieve PMS symptoms, a study in Reproductive Health found.

Sardines, 4.4 oz Can


12 g protein per 2 oz

$0.85 per serving

The miniature fish may not be the epitome of a drool-worthy dinner, but that doesn't mean you should shun the canned superstars. A mere two-ounce serving packs in an impressive 12 grams of protein in addition to anti-inflammatory omega-3s, mood-boosting vitamin B12, and hormone-regulating vitamin D. Stack the seafood over whole-grain toast, pair with sliced avocado, and top with freshly-squeezed lemon juice for a satisfying snack we bet you'll become obsessed with.

2% Cottage Cheese, 24 oz Tub

For an easy way to up your protein intake for the day, couple cottage cheese with fresh or slightly frozen fruit. The curdled cheese provides a solid dose of calcium and B vitamins, and can even help you banish hunger come bedtime thanks to its supply of slow-digesting casein. What's more, the low-cal cheese contains the amino acid tryptophan, which helps induce sleep. Add this cheap protein to your breakfast and even into smoothies for an extra dose of the muscle-building macro.

Light Canned Tuna, 5 oz Can

Tuna canned

15 g protein per 2 oz

$0.99 per serving

Whenever you stock up on the sandwich staple, go for the chunk light tuna—it's harvested from the smaller fish, which reduces the amount of mercury in your can. The cold-water swimmer is loaded with both DHA and EPA, which are fish-derived fatty acids that have been linked to maintaining weight loss, preventing cardiovascular disease, and boosting cognitive function in those with very mild Alzheimer's disease, a study in the international review journal Advances in Nutrition found.

Dry Chickpeas, 25 oz Bag

Roasted chickpeas

10 g protein per ¼ cup dry

$0.27 per serving

Whether you're blending a batch of homemade hummus or tossing the legumes into a hearty salad, chickpeas are one of our top cheap protein foods thanks to their stellar nutritional profile. The low-glycemic legume plays a beneficial role in weight management as well as glucose and insulin regulation and may even provide a positive impact on some markers of cardiovascular disease, according to a study in the journal Nutrients.

Peanut Butter, 16 oz Jar

Toast with peanut butter

7 g protein per 2 tbsp

$0.25 per serving

We love Smucker's Natural peanut butter because it's undeniably creamy and more affordable than other high-end brands that feature the same short ingredient list. Unlike the jars you grew up with (we're looking at you, Skippy and Jif), this pick contains just two ingredients: peanuts and salt. And the main ingredient is no nutritional wallflower: A study published in the journal JAMA Internal Medicine found a link between the consumption of peanuts and a decreased risk for heart disease.

Eggs, 1 Dozen

Deviled eggs

6 g protein per 1 large egg

$0.25 per serving

Fried, scrambled, baked, or poached, eggs are one of our favorite and most affordable proteins thanks to their stellar nutrient density. Eggs are packed with metabolism-boosting choline, which helps you keep your bod in tip-top shape—but this nutrient, along with vitamin D, is only found in the yolk! The oft-avoided orb also contains half the egg's protein content, so make sure you're using the whole egg in your omelets to reap the greatest benefits.

Dry Lentils, 16 oz Bag


13 g protein per ¼ cup dry

$0.33 per serving

Small but nonetheless mighty, lentils are as versatile as they are nutritious. For just 33 cents per serving, you can sneak them into homemade desserts, add them to a vegetarian stew, and mash and mold them into a high-fiber pizza crust. The tiny legumes are a healthful source of anemia-fighting iron and DNA-repairing folate.

Quinoa, 16 oz Bag

Quinoa salad

7 g protein per ¼ cup dry

$0.73 per serving

Whole grains pack in essential amino acids and fiber—and quinoa is no exception. It's a great cheap protein source for vegans and vegetarians because it contains all nine essential amino acids, deeming it a complete protein, as well as packs in more protein per gram than any other grain you'll find stocked in the supermarket.

Canned Wild Pink Salmon, 6 oz Can

13 g protein per 2 oz

$0.99 per serving

Fresh, wild-caught salmon fillets may boast a pretty steep price tag, but you can get the omega-3-rich fish for much less when you grab the cans. For just under a dollar per serving, you'll get 13 grams of metabolism-revving protein as well as heart-healthy omega-3s and fat-soluble vitamins. We especially like Wild Planet's sustainably-caught pink salmon.

Whole Almonds, 25 oz bag

Raw almonds

6 g protein per 1 oz

$0.46 per serving

Looking to add more protein to your go-to snacks? Just grab a handful of raw almonds. We like Blue Diamond's whole natural almonds because they contain just one ingredient (almonds, duh!) and are free of added sodium and sketchy preservatives. If you're looking to boost your workout's fat-burning capacity, aim to nosh on the nuts before hitting the gym. These subtly sweet nuts contain L-arginine, which has been shown to improve performance by helping athletes train for longer, a study in Biology of Sport found. Sounds like it's time to swap out that pseudo-berry-flavored pre-workout!

Organic Tofu, 12 oz pack


8 g protein per 3 oz

$0.42 per serving

Organic tofu, like House Foods', is a smart cheap protein source to add to your cart—it's inexpensive, jam-packed with our star macro, and it's plant-based. The organic variety will ensure you're not getting all the pesticides that come with traditionally-grown soybeans. Grab the silken tofu and add it to our best smoothie recipes for weight loss to boost the bev's slimming powers.
