You're standing in the kitchen, staring at a chicken breast or maybe a handful of almonds, wondering if you're actually hitting your macros. It's a classic dilemma. Most people just guess. They think "an ounce is an ounce," but when it comes to muscle repair and satiety, the math changes depending on what's on your plate. If you've ever typed how many grams of protein in an oz into a search bar while meal prepping, you aren't alone. It’s the foundational question for anyone trying to get lean or bulk up.
Honestly? The answer isn't a single number.
An ounce of steak isn't the same as an ounce of chickpeas. Even the way you cook your food messes with the weight-to-protein ratio. We're going to break down the actual density of these foods so you stop overestimating your intake. Because, let’s be real, most of us are eating way less protein than we think we are.
The Standard Baseline for Animal Proteins
When we talk about meat, there’s a general rule of thumb. Most cooked animal proteins—think chicken, beef, turkey, and pork—hover right around 7 grams of protein per ounce.
But "around" is a dangerous word in nutrition. If you’re eating a fatty ribeye, you’re getting slightly less protein per ounce because fat is taking up some of that weight. If you’re eating a hyper-lean turkey breast, you might nudge closer to 8 or 9 grams. It’s a sliding scale.
Let's look at chicken. It’s the gold standard for gym rats for a reason. A standard 4-ounce serving of cooked chicken breast delivers roughly 28 to 32 grams of protein. If you’re weighing it raw? That’s where people mess up. Raw meat has a high water content. When you throw it in the pan, the water evaporates. The meat shrinks. If you weigh 4 ounces of raw chicken, you’re likely only getting about 22 grams of protein once it’s cooked and on your fork. Always track based on the state you weighed it in.
Seafood and the Lean Advantage
Fish is a bit of a wildcard. Some white fish like cod or tilapia are incredibly protein-dense because they have almost zero fat. You're looking at about 6 grams per ounce. Salmon is different. Because it’s packed with those healthy Omega-3 fats, an ounce of salmon usually gives you about 5 to 6 grams of protein.
Shrimp is a secret weapon. Honestly, it’s basically just protein and water. You can crush an ounce of shrimp and get about 6 grams of protein for very few calories. It's one of the highest protein-to-calorie ratios in the grocery store. If you're struggling to stay in a calorie deficit while hitting a high protein goal, start buying the frozen bags of jumbo shrimp.
Plant-Based Reality Check
This is where things get tricky. People love to say "broccoli has more protein than steak," which is technically true if you measure by calorie, but physically impossible to achieve in a real meal unless you want to eat a literal bucket of greens.

When you ask how many grams of protein in an oz of plant-based sources, the numbers drop significantly compared to meat.
Take lentils. In one ounce of cooked lentils, you're only getting about 2.5 grams of protein. Beans? Roughly the same. To get the same 30 grams of protein you'd get from a small chicken breast, you’d have to eat about 12 ounces of beans. That’s a lot of fiber. Your stomach might not be thrilled with that decision.
Tofu is a bit better, coming in at about 2.3 to 2.5 grams per ounce depending on the firmness. Extra firm tofu has less water, meaning more protein per ounce than the silken variety.

The Nut and Seed Trap
Nuts are delicious. They're also calorie bombs. An ounce of almonds (which is about 23 nuts) has 6 grams of protein. That sounds great! It's almost the same as an ounce of meat. But wait. That ounce of almonds also comes with 14 grams of fat and 160 calories.
Compare that to an ounce of turkey breast: 7 grams of protein and only 30-40 calories.
If you’re using nuts as your primary protein source, you’re going to blow past your daily calorie goal before you ever hit your protein target. Use them as a topper, not the main event. Seeds are similar. Hemp seeds are actually quite impressive, offering about 9 grams of protein per ounce, but again, the fat content is high.
Dairy and Concentrated Sources
Dairy is where we see some of the highest concentrations of protein outside of the butcher shop.

- Greek Yogurt: This is a powerhouse. Because it's strained, it's much denser than regular yogurt. An ounce of non-fat Greek yogurt gives you about 3 grams of protein. A standard 6-ounce container? That’s 18 grams right there.
- Hard Cheeses: Parmesan is surprisingly high in protein. An ounce of Parm has about 10 grams of protein. The problem is the sodium and fat, so you probably shouldn't eat it by the block.
- Cottage Cheese: Another heavy hitter. About 3 grams per ounce.
Why the "Cooked vs. Raw" Debate Matters
If you're serious about your nutrition, you need to pick a side. Most nutritional databases (like Cronometer or MyFitnessPal) default to "raw" weights unless specified.
Meat loses about 25% of its weight during cooking.
If you start with 4 ounces of raw ground beef, you’ll end up with 3 ounces of cooked beef. If you log it as 4 ounces of "cooked" beef, you’re overestimating your protein intake by about 7-8 grams. Over a week, that's a massive discrepancy.
Think about it this way: the protein doesn't disappear when you cook it, but the water does. So, the protein becomes more concentrated in the final product. 1 oz of cooked meat is more protein-dense than 1 oz of raw meat.
Practical List of Protein per Ounce (Cooked)
- Beef (Lean): 7-8g
- Chicken Breast: 8-9g
- Pork Loin: 7g
- Egg: 6g (Note: one large egg is about 1.7 oz)
- Tuna (Canned): 7g
- Peanut Butter: 4g (But 190 calories!)
- Quinoa: 1.2g (Very low, honestly)
- Seitan: 21g (This is the plant-based outlier; it's basically pure wheat gluten)
The Quality Factor: Complete vs. Incomplete
It's not just about the weight. Your body cares about amino acids. Animal proteins are "complete," meaning they have all nine essential amino acids your body can't make on its own. Most plant proteins (except for soy, quinoa, and buckwheat) are "incomplete."
Does this mean plant protein is useless? No. It just means you need to eat a variety of sources throughout the day—like beans and rice—to make sure your body has the full "kit" to build muscle.
How Much Do You Actually Need?
The RDA (Recommended Dietary Allowance) is 0.8 grams of protein per kilogram of body weight. This is a floor, not a ceiling. It’s the minimum to keep your hair from falling out and your skin from sagging.
If you’re lifting weights or trying to lose fat without losing muscle, the research from experts like Dr. Bill Campbell or Dr. Gabrielle Lyon suggests you need way more. Aiming for 0.7 to 1.0 gram of protein per pound of ideal body weight is a much better target for most active adults.

If you weigh 150 lbs, that’s 150 grams of protein.
To hit that, you’d need about 21 ounces of cooked meat per day. That sounds like a lot, but when you break it into three meals of 7 ounces each, it's totally doable.
Common Misconceptions That Mess People Up
One big mistake is the "Protein Bar" trap. A lot of bars claim to be high protein, but check the weight. If a bar is 2 ounces (approx 60g) and only has 10 grams of protein, it's actually less protein-dense than a slice of whole-wheat bread. You want to look for bars where the protein count is at least 30-40% of the total calorie count.
Another one? Bone broth. People drink it thinking it's a protein shake. It's great for collagen, but collagen is an incomplete protein. It lacks tryptophan. It’s great for your joints, but don't count it toward your muscle-building totals for the day.
Actionable Steps for Your Next Meal
Knowing how many grams of protein in an oz is only half the battle. You have to apply it.
First, buy a digital food scale. They’re cheap, usually under $20, and they eliminate the guesswork. For one week, weigh your proteins after you cook them.
Second, aim for "30 at 3." Try to get 30 grams of protein at three different points in the day. This triggers muscle protein synthesis more effectively than eating 90 grams in one sitting and nothing for the rest of the day.
Third, prioritize density. If you're full but haven't hit your protein goal, reach for the "heavy hitters" like egg whites, shrimp, or lean turkey. These give you the most grams per ounce with the least amount of "filler" calories.
Stop guessing. Start weighing. Your progress depends on the data you put in your body. If you treat your protein intake like a rounding error, your results will look like one too. Take the 7-gram rule for meats as your baseline and adjust based on your specific food choices. It's the simplest way to take control of your nutrition.
