Among commonly available meats, rabbit has the highest protein density at about 33 grams per 100 grams of cooked meat. That edges out every standard cut of beef, chicken, pork, and fish by a comfortable margin. But the answer gets more interesting when you look beyond the grocery store to game meats, birds, and seafood.
Rabbit Leads the Standard Lineup
Cooked rabbit meat delivers roughly 33 grams of protein per 100-gram serving, making it about 1.2 times more protein-dense than chicken, which comes in around 27 grams per 100 grams. Rabbit is also exceptionally lean, which is part of why its protein percentage is so high: less fat in the meat means a greater share of each bite is pure protein.
Rabbit isn’t as widely sold as chicken or beef in most Western supermarkets, but it’s a staple in many European, Chinese, and Latin American cuisines. If you can find it at a butcher shop or specialty grocer, it’s one of the most efficient protein sources available from any animal.
Game Meats Pack More Protein Than Beef
Wild and farm-raised game meats consistently outperform conventional beef in protein per serving. USDA testing of alternative red meats found the following protein values per 100 grams when cooked:
- Emu: 28.4 g
- Elk: 26.6 g
- Deer (venison): 26.5 g
- Ostrich: 26.2 g
- Bison: 25.4 g
- Beef: 23.8 g
Emu stands out here, delivering nearly 5 more grams of protein per 100-gram portion than beef. The pattern is consistent: leaner animals tend to have higher protein concentrations because there’s simply less fat diluting the protein content. Wild game animals carry far less intramuscular fat than feedlot cattle, which shifts the ratio in protein’s favor.
Elk and venison are the most accessible game meats in North America, available at many specialty stores and online retailers. Bison has become increasingly mainstream and appears in regular grocery chains. All of these options provide complete proteins, meaning they contain all nine essential amino acids your body can’t produce on its own.
How Poultry and Pork Compare
Chicken breast is the go-to protein source for most people, and for good reason. At roughly 27 grams of protein per 100 grams, it’s widely available and affordable. Turkey performs similarly, with light meat (roasted, no skin) delivering about 28 grams per 100 grams. Dark meat from either bird drops a few grams because of its higher fat content.
Pork varies more depending on the cut. A lean pork leg roast can rival chicken, but fattier cuts like shoulder drop the protein-to-weight ratio noticeably. Ground pork at 96% lean provides about 26 grams of protein per 100 grams cooked, which is competitive with poultry. Fattier ground pork blends fall off quickly.
Beef Protein Depends on the Cut
Beef averages around 24 grams of protein per 100 grams when cooked, but leaner cuts push that number higher. Top round, braised and trimmed, reaches close to 35 grams per 100 grams because so much of the moisture and fat has rendered out during slow cooking. A broiled top sirloin steak, trimmed of visible fat, sits around 30 grams per 100 grams.
The general rule with beef is straightforward: the leaner the cut, the higher the protein concentration. Round cuts and sirloin consistently beat ribeye and chuck for protein density. Cooking method matters too, since braising and roasting drive off water, concentrating the protein in what remains.
Fish and Seafood
Fish is a strong protein source, though raw numbers are slightly lower than lean land animals. Raw yellowfin tuna provides 24 grams of protein per 100 grams, with a remarkable macronutrient profile: 96% of its calories come from protein, with almost no carbohydrates and very little fat. Cooking concentrates that further.
Other high-protein fish include cod, halibut, and tilapia, all of which are very lean white fish that hover in the 20 to 26 gram range per 100 grams cooked. Shrimp is another standout, typically delivering around 24 grams per 100 grams with minimal fat. Fattier fish like salmon provide slightly less protein per serving (about 20 to 22 grams) but compensate with omega-3 fatty acids that lean fish lack.
Why Leanness Determines Protein Density
The pattern across every category is the same: the less fat an animal carries, the more protein-dense its meat will be. This is why rabbit, emu, and venison top the charts. These animals are naturally lean, either because of their biology (rabbits metabolize fat differently than cattle) or because they’re active, free-ranging animals that don’t accumulate the marbling seen in grain-fed livestock.
This also means you can shift the protein density of any meat by choosing leaner cuts and trimming visible fat. A well-trimmed chicken breast and a well-trimmed top round steak are closer in protein content than you might expect. The differences between species, while real, are smaller than the differences between cuts within the same species. If your goal is maximizing protein per bite, prioritize lean cuts from any animal over fatty cuts from a “high-protein” animal.
All animal proteins, regardless of species, are complete proteins. Whether you’re eating rabbit, bison, chicken, or tuna, you’re getting all nine essential amino acids in proportions your body can use efficiently. The choice between them comes down to availability, taste, cost, and how much protein you want per gram of food on your plate.
