How We Calculate Nutrition

We check the protein numbers on Athletic Lift against USDA FoodData Central, the U.S. Department of Agriculture’s nutrient database. Below are the actual figures we use, so you can check our math or use them to build your own meals.

How much cooked protein gets you to 30 or 40 grams

Most of our posts are built around a protein target per serving. This table shows what that takes for the proteins we cook with most, using USDA values for the cooked food.

Cooked proteinProtein in 4 ozFor 30 gFor 40 g
Chicken breast, roasted35 g3.4 oz4.6 oz
Turkey breast, roasted34 g3.5 oz4.7 oz
Top sirloin steak34 g3.5 oz4.7 oz
Flank steak32 g3.8 oz5.1 oz
Ground turkey31 g3.9 oz5.1 oz
Ground beef, 90% lean30 g4.1 oz5.4 oz
Pork tenderloin30 g4.0 oz5.4 oz
Tilapia30 g4.0 oz5.4 oz
Tuna, canned in water29 g4.1 oz5.5 oz
Shrimp27 g4.4 oz5.9 oz
Cod26 g4.6 oz6.2 oz
Salmon, farmed Atlantic25 g4.8 oz6.4 oz
Scallops23 g5.2 oz6.9 oz

The spread is wide. Chicken breast and sirloin reach 30 grams in about 3.5 ounces. Salmon needs closer to 5 ounces, and scallops more than 5. If you eat fish more often than chicken, plan on bigger portions to hit the same number.

Raw weight and cooked weight are not the same

Meat loses water as it cooks, but it keeps its protein. Four ounces of raw chicken breast has about 25 grams of protein and cooks down to roughly 2.9 ounces. Weigh that cooked piece and the same 25 grams now looks like 35 grams per 4 ounces, because the water is gone.

Every portion on Athletic Lift is a cooked weight unless the post says raw. If you weigh your chicken before it goes in the pan, count about 25 grams of protein per 4 raw ounces instead of 35.

Protein that isn’t meat

FoodAmountProtein
Cottage cheese, 2%1 cup24 g
Sardines, canned in oil1 can (3.75 oz)23 g
Firm tofu1/2 cup22 g
Edamame1 cup18 g
Lentils, cooked1 cup18 g
Chickpeas, canned and drained1 can18 g
Plain nonfat Greek yogurt6 oz container17 g
Whole-milk ricotta1/2 cup9 g
Part-skim mozzarella1 oz7 g
Egg1 large6 g
Feta1 oz4 g

Brands vary more here than with meat. Greek yogurt runs anywhere from about 15 to 20 grams per container depending on the brand, so the label on your package beats any table, including this one.

How a recipe total is worked out

For a full recipe, we add up the protein in each ingredient and divide by the number of servings. Meat goes in by cooked weight, and cans by drained weight. Smaller amounts, like a cup of broth or a handful of cheese, are counted too, because a few grams from each adds up across a bowl.

To see how a meal fits into your whole day, add it to the Protein Day Builder.

Who checks the numbers

Rachael Derr, RDN, Athletic Lift’s consulting dietitian, is reviewing the protein, macro, calorie, and allergen numbers in our recipes. Each post she has reviewed is marked “Nutrition reviewed by Rachael Derr, RDN.” If a number looks wrong to you, tell us through our contact page and we will check it against USDA and correct the post.
