# A Weight-Loss Grocery List on a Budget: Cheapest Protein Per Gram _Which foods give you the most protein for the least money and the fewest calories, using current U.S. prices, plus a sample week and a full day of meals._ **The short answer** **The cheapest weight-loss grocery list is built around low-cost protein, filling produce and a plan, so nothing goes to waste.** At September 2026 U.S. average prices, dried beans, milk and eggs deliver 20 grams of protein for about 34 to 60 cents. Boneless chicken breast costs a little more, about 82 cents, but brings only 107 calories with it, which makes it one of the best buys for a calorie deficit. Add potatoes, bananas and frozen vegetables, and cook at home from a list. - **$0.34** - Cost of 20 g of protein from dried beans - **107 calories** - What comes with 20 g of protein from chicken breast - **$2 a day** - A week of protein basics, about 63 g a day - **31%** - Share of food lost at stores and homes in the U.S. Losing weight shouldn't require expensive powders, specialty snacks or meal kits, and some of the most useful foods for a calorie deficit are among the cheapest in the store. The trick is knowing which cheap foods actually help. This guide ranks everyday protein foods by cost per 20 grams of protein, using current government price data, and shows the calories that come with each. It then covers inexpensive foods that keep you full, a sample week of protein for about $14, and a full day of meals for under $5. Finally, it shows practical ways to cut waste and how your spending compares with the USDA's own budget plan. ## What a Budget Grocery List Has to Do A weight-loss grocery list has three jobs. It needs enough protein to keep you full and protect muscle, enough fruit, vegetables and fiber to add volume, and few enough calories to fit your target. It also has to be affordable week after week, or it won't last. Protein is where money matters most. A [2013 meta-analysis](https://doi.org/10.1136/bmjopen-2013-004277) of 27 studies from 10 countries found that the healthiest diets cost about $1.50 a day more than the least healthy ones. The biggest price gap among food groups was in meats and other protein foods, where healthier options cost about 29 cents more per serving. Grains, dairy and fats showed much smaller differences. So if you choose your protein sources wisely, most of the cost gap disappears. The [protein guide](/how-much-protein-to-lose-weight/) explains how much you need. ## The Cheapest Protein, Per 20 Grams Price per pound can mislead, because foods carry very different amounts of protein, so a fairer comparison is the cost of a fixed amount of protein. The table below uses U.S. average retail prices from September 2026, published by the [Bureau of Labor Statistics](https://fred.stlouisfed.org/series/APU0000FF1101), with protein and calories from USDA food data. | Food | Price | Cost of 20 g | Cal | | --- | --- | --- | --- | | Dried beans | $1.67/lb | $0.34 | 316 | | Milk, 2% or lower | $3.59/gal | $0.56 | 303 | | Eggs, large | $2.27/doz | $0.60 | 228 | | Chicken breast, boneless | $4.20/lb | $0.82 | 107 | | Cheddar cheese | $6.13/lb | $1.18 | 352 | | Ground beef | $6.79/lb | $1.74 | 296 | | Yogurt, 8-oz cups | $1.58/cup | $2.65 | 240 | Dried beans win on price, and they bring fiber too, about 14 grams in the amount that supplies 20 grams of protein. Milk and eggs come close behind. Chicken breast costs a little more per gram of protein, but it's the clear winner on calories. It supplies 20 grams of protein for about 107 calories, compared with roughly 300 for beans, milk or ground beef. Single-serve yogurt cups look cheap on the shelf but turn out to be one of the most expensive protein sources here. Buying plain yogurt in a large tub usually costs far less per gram than individual cups. ### Why Calories Matter as Much as Price Some foods look like cheap protein only because they're cheap overall. Dry pasta, for example, costs about 46 cents per 20 grams of protein, and white rice about 69 cents. But that protein comes with roughly 570 calories from pasta and over 1,000 from rice. Those are useful, affordable staples, but they're carbohydrate foods, not protein foods. On a calorie budget, the best value is protein that's cheap in both dollars and calories. That's why a mix works well: chicken or eggs for lean protein, beans for low cost and fiber, and milk or plain yogurt for convenience. Peanut butter, canned tuna, frozen fish, lentils and tofu are other budget proteins worth pricing at your own store. The government no longer publishes national average prices for some of them, so check the unit price on the shelf tag to compare. ## Cheap Foods That Fill You Up The second half of a budget list is food that adds volume for few calories. Fruits and vegetables do this best, and many are inexpensive, especially in season or frozen. | Food | Price per pound | Why it helps | | --- | --- | --- | | Bananas | $0.66 | Sweet, portable snack | | Potatoes | $0.99 | Very filling; keep the skin for fiber | | Iceberg lettuce | $1.64 | Bulk for salads and wraps | | Navel oranges | $1.72 | Fiber and vitamin C | | Tomatoes | $1.99 | Low calorie, adds flavor | Frozen fruits and vegetables deserve a regular spot too. They don't spoil in a few days, they're already washed and cut, and they're often cheaper than fresh out of season. Nutritionally, they hold up well. In a [2015 study](https://doi.org/10.1021/jf5058793) of eight fruits and vegetables, including broccoli, spinach, peas and blueberries, the vitamin content of frozen produce was comparable to fresh and sometimes higher. Oats, cabbage, carrots, onions and canned tomatoes are other low-cost staples that stretch meals. The [hunger guide](/always-hungry-in-a-calorie-deficit/) explains why high-volume, high-fiber foods help you stay satisfied on fewer calories. ## A Week of Protein for About $14 Here's what a simple protein base for one person looks like at September 2026 average prices. It covers the main protein foods for a week, and you'd add produce, grains and a few extras around it. | Item | Cost | Protein | | --- | --- | --- | | Chicken breast, boneless, 2 lb | $8.41 | 204 g | | Eggs, 1 dozen | $2.27 | 75 g | | Dried beans, 1 lb | $1.67 | 98 g | | Low-fat milk, half a gallon | $1.80 | 64 g | | Total | $14.14 | 442 g | That works out to about 63 grams of protein a day for roughly $2. Combined with protein from bread, oats, pasta and vegetables, it gets many people close to their daily target. Your exact needs depend on your weight and goal, and local prices vary, but the proportions hold in most stores. A pound of dried beans cooks into several cups, enough for chili, soups and salads across the week. Cooking a big batch on the weekend saves both money and time, and the [batch-cooking guide](/log-homemade-recipe-calories/) shows how to log it accurately. ## A Full Day of Meals for Under $5 Putting the cheapest foods together shows how far a small budget can go. Here's one day built only from the foods priced above, at September 2026 averages, before cooking oil and seasonings. | Meal | Cost | Calories | Protein | | --- | --- | --- | --- | | Breakfast: 2 eggs, 2 slices of toast, a banana | $0.83 | 402 | 19 g | | Lunch: black beans and rice with tomato | $1.06 | 614 | 30 g | | Dinner: 6 oz chicken breast, potato, salad | $2.48 | 376 | 43 g | | Snack: a cup of 2% milk | $0.22 | 122 | 8 g | | Day total | $4.59 | 1,515 | 100 g | That day also delivers about 31 grams of fiber, most of it from the beans, which is more than many people eat on a much bigger budget. The lunch uses a quarter pound of dry beans and two ounces of dry rice, cooked. The dinner uses half a pound of potato and a quarter pound of lettuce. You'll want to adjust portions to your own calorie target, and a teaspoon of oil or a little cheese adds flavor without wrecking the budget. The point is the pattern: cheap protein at every meal, a starch you can scale up or down, and produce for volume. ## Ways to Spend Less Without Eating Worse Choosing inexpensive foods is only part of the job, because how you shop, store and use food matters just as much. **Waste less.** In the United States, about 31% of food is lost at the store and household level, according to [USDA estimates](https://www.usda.gov/foodwaste/faqs). Food you throw away is money spent on nothing, so planning matters. Plan meals before you shop, buy only what the plan needs, and use leftovers for lunches. **Compare unit prices.** Shelf tags list the price per ounce or per pound in small print. Use it to compare sizes and brands, since the bigger package isn't always cheaper per unit. **Choose store brands.** Staples like beans, oats, rice, frozen vegetables and canned tomatoes are basic foods, and store brands usually cost less. **Skip paid drinks.** At September 2026 prices, a 2-liter bottle of soft drink averaged about $2.27. Regular soda adds calories as well as cost, so water, plain coffee and tea are easy savings on both. **Watch the extras.** Sauces, dressings and snacks can quietly raise both your bill and your calories. The [hidden calories guide](/hidden-calories/) shows which ones add up fastest. ## How Your Budget Compares It helps to know what a realistic food budget looks like. The USDA's Thrifty Food Plan estimates the cost of a nutritious diet prepared at home at the lowest reasonable price. For August 2026, the [USDA report](https://www.fna.usda.gov/research/cnpp/usda-food-plans/cost-food-monthly-reports) put that cost at about $58.50 a week for a woman aged 20 to 50. For a man of the same age, it was $73.60 a week. A family of four with two school-age children came to about $236 a week. These figures assume nearly all meals are cooked at home, so restaurant meals and takeout come on top. If your grocery spending is well above them, the protein and produce choices above are the first places to look for savings. If your budget is tighter than the thrifty plan, assistance programs can help. The Supplemental Nutrition Assistance Program (SNAP) helps eligible households buy groceries, and WIC supports pregnant and postpartum women, infants and young children with specific nutritious foods. Local food banks and pantries frequently stock exactly the staples recommended here, including dried beans, rice, canned vegetables and eggs. Combining these resources with careful planning can stretch a limited budget considerably further, especially for families. Prices also vary by region and store. The Bureau of Labor Statistics figures used here are national city averages, so your local prices may run higher or lower. The comparisons between foods, though, tend to hold wherever you shop. **In WeightPlot** The grocery list is built from your meal plan and grouped by aisle, so you can shop for three, five or seven days at once. Tick items off as you go. It works with WeightPlot's plan, a plan built around your favorites, or a week you planned yourself. ## Common Questions ### What is the cheapest protein for weight loss? Dried beans cost the least per gram of protein. Chicken breast costs more but brings far fewer calories. ### Is frozen produce as healthy as fresh? Yes, in most cases. Research finds frozen fruits and vegetables hold similar vitamin levels, sometimes higher. ### How much should groceries cost per week for one person? USDA's thrifty plan priced it at about $58.50 a week for a woman and $73.60 for a man in August 2026. ## The Bottom Line Eating to lose weight doesn't have to cost more. The key is choosing protein that's cheap in both dollars and calories, then filling the rest of your cart with low-cost produce and staples. Dried beans, milk and eggs are the cheapest sources of protein, while chicken breast offers the most protein for the fewest calories. Add potatoes, bananas, oats and frozen vegetables for volume. Shop from a plan, compare unit prices, choose store brands and use your leftovers, because wasted food is wasted money. A week of protein basics can cost about $14, leaving plenty of room in a realistic budget. **Key takeaways** - **Compare cost per 20 g of protein,** not price per pound. - Dried beans, milk and eggs are cheapest; chicken breast is leanest. - Pasta and rice are cheap but aren't protein foods. - Frozen produce is as nutritious as fresh and wastes less. - Plan meals and use leftovers: about 31% of food is wasted. **Sources** - U.S. Bureau of Labor Statistics.
