Chicken breast and turkey breast top the list of common meats for protein, delivering about 31 grams per 100 grams cooked. But if you’re open to less conventional options, game meats and rabbit push even higher. The answer depends on the cut, how it’s prepared, and whether you’re optimizing for pure protein or protein relative to calories.
How Meats Rank by Protein Content
When you compare cooked meats per 100 grams (roughly 3.5 ounces), a clear hierarchy emerges. Lean beef cuts like eye of round and top round steak hit about 30 grams of protein per 100 grams cooked. Skinless chicken breast and turkey breast land in the same range, around 29 to 31 grams. Game meats like venison and elk come in at about 26 to 27 grams per 100 grams in USDA data, though leaner preparations can push higher. Rabbit meat stands out at 29.1 grams per 100 grams.
Pork tenderloin, often overlooked, delivers roughly 26 grams per 100 grams cooked. Chicken thighs without skin come in slightly lower, around 25 grams. Fish and seafood generally provide 7 grams per ounce (similar to most meats), with shellfish like shrimp, crab, and lobster slightly lower at about 6 grams per ounce.
Jerky deserves a mention if you’re comparing by weight. Beef or turkey jerky packs 10 to 15 grams of protein per ounce because nearly all the water has been removed. That’s roughly double what you’d get from the same weight of fresh cooked meat.
Why the Cut Matters More Than the Animal
Picking “chicken” or “beef” isn’t enough to know how much protein you’re getting. The specific cut makes a bigger difference than the species. A 6-ounce chicken breast provides about 52 grams of protein at 280 calories. A 6-ounce prime rib delivers only 38 grams at 656 calories. That’s less protein for more than twice the calories, all because prime rib carries far more fat.
Within beef alone, the range is dramatic. Lean cuts from the round (eye of round, top round, sirloin tip) deliver 27 to 30 grams of protein per 100 grams cooked with minimal fat. Fattier cuts like ribeye or prime rib have less protein per serving because fat displaces protein by weight. If your goal is maximizing protein per calorie, lean cuts from any animal will outperform fatty cuts from any animal.
Game Meats Pack Protein With Less Fat
Venison and elk are worth knowing about if protein density matters to you. According to USDA research, cooked venison provides 26.5 grams of protein per 100 grams with only 8.2 grams of fat. Elk is nearly identical at 26.6 grams of protein and 8.7 grams of fat. Compare that to cooked beef at 23.8 grams of protein and 15.1 grams of fat. Game meats give you more protein and roughly half the fat.
Bison falls somewhere in between. It matches beef on protein (25.4 grams per 100 grams cooked) but its fat content varies widely depending on how the animal was raised. Farm-raised bison can carry fat levels similar to beef.
Cooking Concentrates Protein
One detail that trips people up: raw and cooked weights give very different numbers. Cooking drives off water, so the protein becomes more concentrated. Raw chicken breast has about 23 grams of protein per 100 grams. Cook that same chicken and measure 100 grams of the result, and you’ll get closer to 30 grams. No protein was created. You’re just measuring a denser product because the water evaporated.
This matters when you’re tracking intake. If a recipe calls for 8 ounces of chicken and you weigh it raw, you’re getting less protein per measured gram than if you weigh it cooked. Most nutrition labels for raw meat reflect the lower number, so keep that in mind when comparing foods.
Meat Protein Is Highly Usable
Beyond the raw gram count, meat protein is among the highest quality protein your body can get. Using the DIAAS scoring system (the method recommended by the UN’s food and agriculture body for measuring protein quality), beef and pork burgers score higher than plant-based alternatives. The key reason is that meat contains all essential amino acids in proportions your body can fully use, with no limiting amino acid. Some plant proteins fall short on sulfur-containing amino acids, which means your body can’t use 100% of what you eat for muscle repair and other functions.
In practical terms, 30 grams of protein from chicken breast or steak does more for muscle building than 30 grams from most plant sources. This doesn’t mean plant protein is useless, but it does mean the numbers on the label tell a slightly incomplete story.
How Much Protein Per Meal Actually Counts
Eating a 16-ounce steak doesn’t mean your body uses all 80-plus grams of protein for building muscle. Research suggests that muscle-building benefits max out at roughly 20 to 25 grams of high-quality protein per meal in younger adults. Anything beyond that still gets used for energy or other body functions, but it won’t accelerate muscle repair.
A more practical target, based on a review from researchers at CUNY, is 0.4 grams of protein per kilogram of body weight per meal, spread across at least four meals. For a 175-pound person, that works out to about 32 grams per meal. That’s one chicken breast, a 4.5-ounce serving of lean beef, or a similar portion of pork tenderloin. Spreading your protein across the day matters more than loading it all into dinner.
Quick Comparison by Serving
- Chicken breast (skinless, roasted, 3 oz): ~24 g protein
- Turkey breast (skinless, roasted, 3 oz): ~24 g protein
- Lean beef eye of round (cooked, 3 oz): ~25 g protein
- Pork tenderloin (roasted, 3 oz): ~22 g protein
- Venison (cooked, 3 oz): ~22 g protein
- Elk (cooked, 3 oz): ~22 g protein
- Chicken thigh (boneless, skinless, 1 thigh): ~29 g protein
- Beef/turkey jerky (1 oz): 10–15 g protein
The differences between the top contenders are small enough that your best move is choosing the leanest cut of whatever meat you enjoy eating consistently. A few grams per serving won’t matter if you’re hitting your daily total across multiple meals.
