The most protein-dense fresh meat is chicken breast, with about 24 grams of protein per 3-ounce serving and only 0.7% fat by weight. But several game meats come remarkably close, and if you count dried meats like biltong, the numbers jump dramatically, past 50 grams per 100 grams. The answer depends on whether you care about protein per weight, protein per calorie, or both.
Top Meats Ranked by Protein Content
Data from the Alaska Department of Fish and Game provides one of the most comprehensive side-by-side comparisons of wild and domestic meats. Here’s how the top contenders stack up per 100 grams of raw meat:
- Ptarmigan: 24.8g protein, 2.3g fat, 128 calories
- Grouse: 23.8g protein, 0.7g fat, 142 calories
- Mule deer (venison): 23.7g protein, 1.3g fat, 145 calories
- Chicken breast: 23.6g protein, 0.7g fat, 135 calories
- Elk: 22.8g protein, 0.9g fat, 137 calories
- Caribou: 22.6g protein, 3.4g fat, 127 calories
- Moose: 22.1g protein, 0.5g fat, 130 calories
- USDA Choice beef: 22.0g protein, 6.5g fat, 180 calories
- Buffalo (bison): 21.7g protein, 1.9g fat, 138 calories
The differences in raw protein grams are small. What separates these meats is fat content, which affects how many calories you consume to get that protein. Moose has just 0.5 grams of fat per 100 grams, making it arguably the leanest meat available. Lean ground beef, by contrast, contains 20.7 grams of fat and 264 calories for only 17.7 grams of protein.
Protein Per Calorie: A Better Measure
If your goal is maximizing protein while minimizing calories, the ratio of protein to total calories matters more than grams alone. Chicken breast and grouse both pack about 23.6 to 23.8 grams of protein into roughly 135 to 142 calories, meaning over 65% of their calories come from protein. Moose is even more efficient: 22.1 grams of protein in just 130 calories, with almost no fat to speak of.
Compare that to a fattier cut like lean ground beef, where protein accounts for less than 27% of total calories. You’d need to eat nearly 50% more ground beef by weight to match the protein you get from a single chicken breast, and you’d take in far more calories doing it. For anyone tracking macros or eating in a calorie deficit, this distinction is what actually matters at the grocery store or the dinner table.
Where Pork and Turkey Land
Turkey and pork are common alternatives to chicken, and both hold up reasonably well. A whole raw turkey averages about 21.6 grams of protein per 100 grams, though turkey breast specifically runs higher, closer to chicken breast levels. Fresh broiled pork loin delivers 25.6 grams of protein per 100 grams, which actually edges out chicken. The trade-off is fat: pork loin carries 11.1 grams of fat compared to chicken breast’s 0.7 grams.
So pork loin may technically contain more protein per weight than chicken breast, but it comes packaged with significantly more fat and calories. If you’re purely counting protein grams and don’t care about fat, pork loin is a strong option. If you want the best protein-to-calorie ratio, chicken breast and turkey breast win.
Dried Meats Change the Math Entirely
Removing water from meat concentrates everything, including protein. Biltong (a type of air-dried beef popular in South Africa) can contain 56 grams of protein per 100 grams, more than double what you’d find in fresh chicken breast. Even smoked varieties land around 49 grams per 100 grams.
Beef jerky follows a similar pattern, though commercial jerky often includes added sugars and sodium that lower the overall protein percentage. If you’re looking for the single most protein-dense meat product by weight, biltong is hard to beat. Just keep in mind you’re comparing dehydrated food to fresh food. Ounce for ounce before drying, the starting beef had a protein content similar to any other cut.
Organ Meats Are Not Protein Powerhouses
Liver, heart, and kidney are often recommended for their micronutrient density, and that reputation is earned. But their protein content is actually lower than muscle meat. Raw beef liver contains 20.4 grams of protein per 100 grams, beef heart has 17.7 grams, and beef kidney has 17.4 grams. All three fall below chicken breast, venison, and most game meats. Organ meats are worth eating for their vitamins and minerals, but they’re not the right choice if protein density is your primary goal.
Protein Quality Across Meats
Not all protein is absorbed equally. Researchers measure this using a score called DIAAS, which evaluates how well your body can actually use the amino acids in a food. All meats score well, but there are some differences. Pork loin scores as high as 139% for adults (anything over 100% is considered excellent quality). Medium-cooked beef ribeye hits 130%, while cooked ground beef drops to 99%.
Cooking method affects these scores. Overcooking meat tends to lower protein digestibility. Well-done beef ribeye scores 107% compared to 130% for medium, a meaningful drop. If protein quality matters to you, cooking meat to medium rather than well-done preserves more usable protein. That said, every meat on this list scores high enough that differences in digestibility are far less important than simply eating enough total protein.
Practical Picks for Most People
Unless you hunt or have access to specialty game, your realistic options come down to a few grocery store staples. Boneless, skinless chicken breast remains the most practical high-protein meat for most people: widely available, inexpensive, extremely lean, and roughly 24 grams of protein per 3-ounce cooked serving. Turkey breast is nearly identical in profile and works as a direct substitute.
Bison is increasingly available in supermarkets and offers 21.7 grams of protein with only 1.9 grams of fat per 100 grams, a leaner alternative to beef with a similar flavor. Pork loin is another strong contender if you don’t mind the higher fat content, delivering the most raw protein grams of any common grocery store meat at 25.6 grams per 100 grams. For snacking, biltong or high-quality jerky with minimal added sugar gives you the highest protein per bite of any meat product available.
