Search for the “highest-protein meat” and it sounds as though there should be one obvious winner. Put comparable lean cooked cuts on the same scale and the more interesting result is how close they are: most land between about 27 and 33 grams per 100 grams.
That changes the question. Instead of chasing first place, it is more useful to see how large the gaps really are, how much cooking water loss influences the numbers and what starts to matter once protein is nearly tied.
Protein in 100 grams of cooked lean meat
| Meat | Protein/100 g |
|---|---|
| Cooked rabbit | ~33 g |
| Skinless chicken breast | 31 g |
| Skinless turkey breast | 29.5 g |
| Lean beef | ~29 g |
| Lean lamb | ~28 g |
| Lean pork | ~27 g |
Rabbit sits at the top and lean pork at the bottom, but the entire spread is only about 6 g per 100 g. Chicken, turkey and lean beef are even closer at 31, 29.5 and about 29 g. This is less a division between “high-protein” and “low-protein” meats than a cluster of already protein-dense foods.
The comparison also depends on choosing similar cuts. A skinless breast, a trimmed loin and a heavily marbled cut can all come from different animals but differ more in fat and water than in their basic protein potential. A ranking is most useful when the foods are prepared in comparable ways.
On a normal plate, the leader pulls away much less
A 5-ounce / 142 g serving of rabbit provides roughly 47 g protein and chicken about 44 g. Turkey supplies about 42 g, lean beef around 41 g and lean pork around 38 g.
The gap from first to last is therefore about 9 g in a full serving. That is real, but it is nowhere near a several-fold difference. Choosing a meat for a two- or three-gram protein edge often matters less than the cut, fat, iron or simply eating a wider variety of protein foods.
Serving size can also overwhelm the ranking order. Four ounces of chicken and six ounces of lean pork will not follow the per-100-g leaderboard because the larger portion simply contains more food. That is why the table is a concentration comparison, not a prescription for how much to eat.
Once protein is close, cut and nutrient profile matter more
Lean beef and turkey breast both sit near 29–30 g protein/100 g, yet beef commonly provides around 2–3 mg iron/100 g compared with about 1 mg in turkey breast. That is a more meaningful distinction than half a gram of protein.
Pork shows why the cut deserves equal attention. Lean tenderloin may be near 27 g protein and about 5 g fat/100 g, while bacon can exceed 40–50 g fat/100 g. The animal is the same; the food on the plate is nutritionally very different.
The same logic applies within beef and lamb. Trimming visible fat, choosing a leaner cut and using a cooking method that does not add large amounts of fat can change calories substantially while leaving the protein contribution strong.
Cooking explains why protein rises per 100 grams
Raw chicken breast may contain roughly 22–23 g protein/100 g and cooked breast about 31 g. Cooking did not create protein; it removed water.
If 120 g of raw meat containing 27 g protein finishes at 90 g after cooking, those same 27 g are now concentrated into less weight. Raw-versus-cooked comparisons can therefore create artificial “winners.”
Cooking losses are not identical across cuts or methods. A thin piece cooked until quite dry can lose more water than a thicker, juicier piece, which changes the nutrient concentration per 100 g even when the original meat was similar. For practical comparisons, cooked should be compared with cooked and raw with raw.
Cured and dried meats concentrate protein — and sodium
Jerky and cured ham can match or exceed fresh cooked meat per 100 g because much of their water has been removed. A cured ham can land around 30–35 g protein/100 g while also carrying a substantial amount of sodium.
The protein number is legitimate; the product is different. A fresh loin and a dried or cured meat are not interchangeable just because they appear close in a protein ranking.
What a 5-ounce serving contributes
| Meat | Approx. protein |
|---|---|
| Rabbit | ~47 g |
| Chicken | 44 g |
| Turkey | 42 g |
| Lean beef | ~41 g |
| Lean pork | ~38 g |
At serving size, every one of these is a substantial protein source. The ranking quantifies the gap; the practical choice is usually more about which cut you are buying and what else you want from the meal.
The practical takeaway
Rabbit and chicken breast sit near the top, but turkey, beef, lamb and lean pork remain close. Within this group, choosing a lean cut and varying protein sources usually matters more than chasing a few extra grams per 100 grams.
If protein is the only question, all of these meats are concentrated sources. If the real goal is building a balanced meal, iron, fat, sodium, portion size, price and the rest of the plate deserve at least as much attention as the exact ranking position.
Frequently asked questions
Which meat has the most protein?
Among lean cooked meats, rabbit can be around 33 g/100 g and chicken breast about 31 g/100 g.
Does chicken have more protein than beef?
Chicken breast is about 31 g/100 g and many lean beef cuts around 29 g, so the difference is small.
Why does cooked meat show more protein?
Cooking removes water and concentrates the existing protein into less total weight.
