How much protein is in an egg, really?

One large egg has about 6g of protein. That's the headline number every search result will give you. The follow-up questions are where it gets interesting.

Big egg vs. large egg vs. jumbo egg

Egg sizes in the US:

• Medium: ~5g protein, 65 cal
• Large: ~6g protein, 72 cal
• Extra large: ~7g protein, 80 cal
• Jumbo: ~8g protein, 90 cal

Most recipes and most labels assume "large" by default. If you're buying jumbos, your protein per egg is closer to 8g and your calories are 25% higher than the chart says.

Whole egg vs. egg white

A large whole egg: 6g protein, 5g fat, 72 cal. A large egg white only: 3.6g protein, 0g fat, 17 cal.

If your goal is maximum protein per calorie, egg whites are unbeatable. If your goal is satiety, the yolk earns its keep — the fat slows gastric emptying and most of the micronutrients (choline, lutein, B12, vitamin D) live in the yolk.

The middle path that works for most people: 2 whole eggs + 4 whites = ~26g protein, 200 cal, all the yolk benefits with cleaner macros.

Cooked vs. raw

Cooking doesn't change the protein content meaningfully, but it does change protein availability. Raw eggs have a digestibility around 50%. Cooked eggs are around 90%. So while the label says 6g either way, you actually absorb more from the cooked version. Raw egg in a smoothie is romantic; it's also half-wasted.

How many eggs is "too many"

The blanket cholesterol-fear-of-eggs era has been over for a decade in the major guidelines. For most people, 2–3 eggs a day is fine. People with familial hypercholesterolemia or known LDL hyperresponse to dietary cholesterol are the genuine edge case — talk to your doctor if that's you.

Eggs vs. other quick proteins

Per 100 calories:

• Eggs: ~8g protein
• Greek yogurt (nonfat): ~17g
• Cottage cheese (low-fat): ~14g
• Whey protein: ~22g
• Chicken breast: ~22g

Eggs are not the highest protein-per-calorie option. They are the most versatile. They cook in 90 seconds, they take any seasoning, they're cheap, they keep for weeks. That ergonomic profile matters more than squeezing out an extra gram.

What this looks like in tracking

Snap a photo of your scrambled eggs and the app will identify them, ask if you used butter or oil, and let you confirm the count. The most common log error is forgetting the cooking fat — a tablespoon of butter is 100 calories of pure fat that the egg alone won't show.

The egg is the kitchen's best protein utility player. Treat it like one.
