Cheap foods for muscle gain can build just as much mass as expensive steaks and fancy powders. You do not need to spend 200 dollars a week at the grocery store to get big. In fact, some of the cheapest items on the shelf pack the most protein per dollar.
To build size, you need a daily calorie surplus and about 0.8 to 1 gram of protein for every pound of your body weight. A 170-pound lifter needs roughly 170 grams of protein daily. You can hit that exact target for less than 6 dollars a day using simple staples from any basic supermarket.
The Best Cheap Eggs for Mass
Eggs are the king of budget muscle building. One large egg gives you 6 grams of protein, 5 grams of fat, and about 70 calories. A carton of 12 eggs usually costs around 2.50 to 3.00 dollars, which means you get 72 grams of total protein for just three bucks.
Whole eggs pack healthy fats that help your body produce testosterone. Scientists measure how well your body uses protein with a scale called biological value. Whole eggs sit at the top of that list with a score of 100. That means your body uses almost every single gram of protein in an egg to repair broken muscle fibers.
Try eating four whole eggs every morning. Boil them ahead of time if you work early. Four eggs give you 24 grams of protein right away for less than a dollar. Pair them with two slices of whole wheat bread, and you start your day with 34 grams of protein in your system.

Canned Tuna and Whole Milk
Canned light tuna gives you pure protein with almost zero fat or carbs. One standard 5-ounce can costs about 1.20 dollars and holds 30 grams of protein. That is one of the cheapest protein ratios you can buy anywhere.
Drain a can of tuna, mix it with a spoonful of mayonnaise, and eat it on toast. You get a solid 35-gram meal for under 1.50 dollars. Just limit your tuna intake to three or four cans a week to keep your mercury levels safe. Swap in canned chicken on the other days for the exact same budget boost.
Whole milk is another cheap cheat code for skinny guys who struggle to gain weight. One gallon costs around 3.50 dollars and packs 128 grams of protein alongside 2,400 calories. Drinking two large glasses of whole milk each day adds 16 grams of protein and 300 calories to your diet for less than 60 cents.
Liquid calories do not fill you up like solid food does. If you struggle to finish your meals, drinking your calories makes hit your targets much easier. Milk also contains both whey and casein, which digest at different speeds to keep your muscles fed for hours.
Dry Beans and Oats for Clean Carbs
Protein builds muscle, but carbs give you the raw energy to lift heavy weights. Dry black beans, pinto beans, and lentils are crazy cheap fuel. A one-pound bag of dry black beans costs around 1.50 dollars. That single bag gives you about 90 grams of protein and over 300 grams of slow-digesting carbs.
Soak your dry beans overnight in water, then boil them for an hour with salt and garlic. One cup of cooked black beans delivers 15 grams of protein and 40 grams of carbs. Eat them with white rice after a hard workout to refill your glycogen stores without hurting your wallet.
Rolled oats are another essential staple. A big tub of oats costs roughly 4.00 dollars and contains 30 servings. One cup of dry oats gives you 10 grams of protein, 54 grams of carbs, and 300 calories. It is the best morning food for long-lasting gym energy.
Mix your morning oats with warm milk, a scoop of peanut butter, and a chopped banana. That single bowl gives you 600 rich calories and 22 grams of protein. You can learn more about Daily Habits That Slowly Burn Fat Without Crazy Diets to see how daily food tracking fits into your long-term goals.
Cheap Cottage Cheese and Peanut Butter
Cottage cheese is packed with casein protein. Casein digests slowly in your stomach over six to eight hours. That slow release makes it the best food to eat right before you go to sleep. A 24-ounce tub costs about 2.80 dollars and contains 78 grams of protein.
Eat one cup of low-fat cottage cheese right before bed. That small snack feeds your body 28 grams of protein while you rest. If you dislike the lumpy texture, blend it into a smooth paste with a spoonful of honey or a few frozen berries.
Peanut butter is the ultimate low-cost calorie booster. A standard two-pound jar costs around 4.00 dollars and delivers over 4,500 total calories. Two tablespoons give you 8 grams of protein, 16 grams of healthy fats, and 190 calories for about 15 cents.
Spread peanut butter on your fruit, stir it into your oatmeal, or eat a direct spoonful right after your meals. Adding just two tablespoons of peanut butter to your daily intake adds 1,330 extra calories to your week. That simple trick alone can help a skinny lifter finally break through a weight plateau.
How to Shop and Cook on a Budget
Buying in bulk saves you serious cash over a full year of training. Buy your chicken breasts in family packs of five pounds or more. Five pounds of chicken breast usually costs around 15 dollars. That bulk pack gives you roughly 500 grams of total cooked protein.
Take one hour every Sunday to cook your food ahead of time. Season three pounds of chicken breasts with salt, pepper, and paprika. Bake them at 400 degrees Fahrenheit for 25 minutes. Slice the cooked meat and divide it evenly into five plastic containers with white rice and frozen broccoli.

Frozen vegetables are another easy budget win. A two-pound bag of frozen broccoli costs about 2.50 dollars. Frozen veggies are picked at peak ripeness, so they hold the exact same vitamins as fresh produce. Steam them in your microwave for three minutes to complete any meal.
