The simplest way to get extra protein is to rethink what you’re already eating: swap low-protein staples for higher-protein alternatives, add protein-rich ingredients to meals you already make, and spread your intake more evenly across the day. Most adults need at least 0.8 grams of protein per kilogram of body weight, which works out to about 53 grams a day for a sedentary 140-pound person. But newer dietary guidelines suggest active adults and older adults may benefit from 1.2 to 1.6 grams per kilogram, which can nearly double that target.
How Much Extra You Actually Need
The gap between what you’re eating and what you need is probably smaller than you think. The average American diet is already considered high in protein. For someone weighing 155 pounds, the baseline recommendation of 0.8 g/kg comes to about 56 grams per day. At the higher end of 1.6 g/kg, that same person would aim for roughly 113 grams. If you’re strength training, recovering from surgery, or over 65, the higher range is where most of the benefit lies.
A useful rule of thumb: a piece of chicken, beef, pork, or fish about the size of a deck of cards weighs roughly 3 ounces and delivers around 21 grams of protein. If you can picture that portion, you can start estimating how close your current meals get you to your target.
Best High-Protein Foods by Category
Some foods pack protein far more efficiently than others. Here are the top options, organized so you can pick what fits your diet.
- Greek yogurt (plain, nonfat): 12 to 18 grams per 5-ounce container
- Cottage cheese or part-skim ricotta: 14 grams per half cup
- Dry-roasted edamame: 13 grams per ounce
- Ultra-filtered high-protein milk: 13 grams per 8-ounce glass
- Beef or turkey jerky: 10 to 15 grams per ounce
- Lentils: 9 grams per half cup
- Black, kidney, or navy beans: 8 grams per half cup
- Fresh or frozen edamame: 8 grams per half cup
- Regular milk (skim or 1%): 8 grams per glass
- Peanut butter: 7 grams per 2-tablespoon serving
Greek yogurt and cottage cheese stand out for people who want high protein without cooking. They’re dense enough in protein that swapping them in for a regular snack can add 15 or more grams to your day with zero effort.
Easy Ways to Add Protein to Meals You Already Eat
You don’t need to overhaul your diet. Small additions to foods you’re already preparing can add 7 to 15 grams per meal without changing the flavor much.
Add extra egg whites to scrambled eggs, omelets, pancake batter, or French toast batter. One egg white adds about 3.5 grams, and two or three mixed in are nearly undetectable in most recipes. Sprinkle nuts, seeds, or wheat germ on top of yogurt, cereal, salads, or oatmeal. Stir peanut butter or almond butter into smoothies, oatmeal, or even plain yogurt. Swap regular milk for ultra-filtered high-protein milk in cereal, coffee, or baking, and you pick up an extra 5 grams per glass without changing the taste.
Hummus works as a higher-protein replacement for mayo or butter on sandwiches, delivering about 7 grams per third of a cup. And adding a half cup of lentils or beans to soups, stews, salads, or pasta sauces is one of the cheapest protein boosts available.
Why Timing and Distribution Matter
Most people eat the bulk of their protein at dinner and very little at breakfast. Research suggests this pattern is less effective for maintaining muscle than spreading protein more evenly throughout the day. A study examining protein distribution found that people who ate more of their protein at breakfast had higher muscle mass and grip strength than those who loaded protein at dinner.
The likely reason involves how your body builds muscle after a meal. Muscle repair and growth get triggered when a meal delivers enough of the amino acid leucine, roughly 2 to 3 grams worth. That translates to about 20 to 30 grams of protein per meal, depending on the protein source. Eating 60 grams at dinner and 10 at breakfast means you’re only hitting that trigger once a day instead of two or three times.
A practical fix: aim for at least 20 grams of protein at each meal. Breakfast is usually the weakest link. Adding Greek yogurt, eggs, or a glass of high-protein milk can bring a cereal-and-toast breakfast from 8 grams into the 20-to-25 range.
Protein Powders: When They Help
Protein powder isn’t necessary for most people, but it’s a convenient option when whole foods aren’t practical. The three most common types are whey, casein, and soy, and they perform differently.
Whey is absorbed quickly and triggers the highest rate of muscle protein building, both at rest and after exercise. After a workout, whey stimulated muscle repair about 122% more than casein and 31% more than soy. Soy protein is also fast-absorbing and outperformed casein by roughly 69% after exercise, making it a solid plant-based alternative. Casein digests slowly, which is why some people use it before bed, though its immediate muscle-building signal is weaker.
If you’re choosing one powder for general use, whey delivers the most muscle-building benefit per scoop. If you avoid dairy, soy isolate is the closest plant-based match. Most powders provide 20 to 30 grams of protein per serving, enough to hit the threshold for stimulating muscle repair in a single shake.
Getting Enough Protein on a Plant-Based Diet
Plant proteins are not incomplete in the way people often fear, but individual plant foods do tend to be low in one or two specific amino acids. Grains, nuts, and seeds are typically low in lysine, while legumes are low in methionine. The fix is simple: eat both categories over the course of a day. Rice and beans, lentil soup with bread, or a trail mix with peanuts and seeds all cover the gaps.
You don’t need to combine these foods in the same meal. Eating beans at lunch and almonds as an afternoon snack still gives your body all nine essential amino acids it needs. The key for plant-based eaters is making sure legumes (beans, lentils, chickpeas, peanuts, soy) show up regularly, since they supply the lysine that most other plant foods lack.
Soy-based foods are the exception: tofu, tempeh, edamame, and soy milk are complete proteins on their own. Dry-roasted edamame, at 13 grams per ounce, is one of the most protein-dense snacks available regardless of diet.
When More Protein Can Backfire
For people with healthy kidneys, protein intakes in the range of 1.2 to 1.6 grams per kilogram appear safe. But there is a ceiling. Extremely high intakes, particularly when combined with creatine supplements, can overwhelm the kidneys’ ability to clear protein waste products, even in people without preexisting kidney disease.
The bigger concern is undiagnosed kidney problems. An estimated 90% of people with chronic kidney disease don’t know they have it. For those individuals, pushing protein intake higher could accelerate damage they’re not aware of. If you haven’t had basic blood work in a while and you’re planning to significantly increase your protein intake, a simple kidney function test (usually part of routine blood work) can rule out any issues.
For most people, getting extra protein from whole foods and spreading it across meals is both effective and safe. The risks tend to come from extreme supplementation, not from adding an extra serving of Greek yogurt or a handful of lentils to your lunch.
