How Much Protein in One Egg? Facts & Daily Needs

You’ve probably heard that eggs are a good source of protein, but when you’re staring at a carton in the grocery aisle, the numbers can feel fuzzy. A single large egg delivers about 6.3 grams of high-quality protein — enough to kickstart your morning but not nearly enough to cover your daily needs by itself, so this guide breaks down exactly how much protein is in one egg, compares whites versus yolks, and shows you how to fit eggs into a solid daily protein plan.

Protein in one large egg: 6.3 g ·
Protein in one egg white: 3.6 g ·
Protein in one egg yolk: 2.7 g ·
Calories in one large egg: 72 ·
Protein in one boiled egg: 6.3 g ·
Protein in one medium egg: 5.5 g

Here are the key protein numbers for eggs.

How Much Protein Is in One Egg?

Eggs pack a surprising amount of protein into a small shell. The exact number depends on the size of the egg and whether you eat the whole thing or just the white.

Protein in Different Egg Sizes

One large egg — the standard used in most nutrition guides — contains about 6.3 grams of protein, according to the Egg Nutrition Center (industry-funded research body). A medium egg, which is a bit smaller, drops to 5.5 grams. Jumbo eggs can push past 7 grams.

Six sizes, one pattern: the bigger the egg, the more protein, but the ratio stays roughly constant at about 12–13% protein by weight.

Protein in Egg White vs. Yolk

If you separate the egg, the white and yolk each contribute a different share. For a large egg, the white holds about 3.6 grams of protein and the yolk about 2.7 grams (Egg Info, UK industry authority). By weight, the yolk is actually more protein-dense — 16.4 g per 100 g compared to 10.8 g per 100 g in the white (Egg Info, UK industry authority). But because the white makes up a larger volume, it delivers more total protein per egg.

Protein in Boiled vs. Omelette

Cooking method barely changes the protein count. A boiled egg and a scrambled omelette (no added milk) both contain the same 6.3 grams of protein per large egg, because protein is not destroyed by normal cooking temperatures. The difference is in the fat and calories from oil or butter added during frying.

Are Two Eggs Enough Protein for a Day?

Two eggs give you a solid start, but they won’t cover your daily protein target on their own.

Recommended Daily Protein Intake

Official guidelines vary by country, but the numbers cluster in a narrow range. The U.S. Dietary Guidelines for Americans recommend at least 56 grams per day for adult men and 46 grams per day for adult women (Healthline, citing USDA guidelines). The Recommended Dietary Allowance (RDA) is 0.8 grams per kilogram of body weight per day (PubMed, peer-reviewed consensus). For a 70 kg person, that’s 56 grams.

For athletes and active people, the need jumps to 1.2–2.0 g per kg, making eggs alone obviously insufficient.

Protein Contribution of Two Eggs

Two large eggs provide about 12.6 grams of protein — roughly 23% of the RDA for a sedentary man and 27% for a sedentary woman. That’s a decent breakfast, but it leaves a gap of 33–43 grams to fill from other foods.

Comparing Eggs to Other Protein Sources

Eggs are efficient, but not the most concentrated protein source. A 4-ounce chicken breast delivers about 30 grams, a cup of Greek yogurt around 15–20 grams, and a cup of cooked lentils about 18 grams. The table below shows how eggs stack up against common protein foods per serving.

Six protein sources, one pattern: eggs are a solid supporting player, not the headliner, for hitting daily protein targets.

The pattern: two eggs deliver about as much protein as a half-cup of cottage cheese, but less than half of what you’d get from a chicken breast. For a 70 kg adult, you’d need roughly 5 eggs to hit 30 grams — a plausible breakfast but not a sustainable daily strategy.

How Can I Get 100g of Protein a Day?

Hitting 100 grams of protein daily is achievable with a mix of whole foods. Eggs can play a role, but they can’t do it alone.

High-Protein Foods List

To reach 100g, you’ll want to include a variety of sources. Here are some reliable options, with protein counts per standard serving:

• Chicken breast (4 oz) – 30g
• Greek yogurt (1 cup) – 15–20g
• Large eggs (2) – 12.6g
• Cottage cheese (½ cup) – 14g
• Lentils, cooked (1 cup) – 18g
• Quinoa, cooked (1 cup) – 8g
• Almonds (¼ cup) – 7g
• Tuna (3 oz can) – 22g

Sample Day Plan for 100g Protein

Breakfast: 2 eggs + 1 cup Greek yogurt (about 28g protein). Lunch: Chicken breast salad with 4 oz chicken (30g). Dinner: 1 cup lentils + ½ cup cottage cheese (32g). Snack: ¼ cup almonds (7g). Total: 97g. That’s close to 100g without any protein powders. If you want to add variety, a bowl of chili made with beans and meat can easily add another 15–20g per serving.

Protein Timing and Distribution

Spreading protein across meals helps with muscle synthesis. Aim for 20–30g per meal. Eggs are perfect for breakfast or snacks. For post-workout, a chicken breast or Greek yogurt fits better. And if you’re into strength training, a close grip bench press guide can help you build upper body strength — but only if you’re actually eating enough protein to recover.

What Food Has 30 Grams of Protein?

Several common foods deliver roughly 30 grams of protein in a single serving. Know your portions and you can hit that number easily.

Foods Providing 30g Protein

• 4 oz (113 g) chicken breast, cooked – 30g
• 1 cup (245 g) Greek yogurt – 15–20g (need 1.5 cups to hit 30g)
• 1 cup cooked lentils – 18g (need 1.5 cups)
• 3 large eggs – 18.9g (need 5 eggs to hit 30g)
• 3 oz (85 g) canned tuna – 22g (need 4 oz)
• 1 scoop whey protein powder – 25–30g

Portion Sizes

30 grams is a substantial amount for a single sitting. It’s roughly the size of a deck of cards for meat, or two cups of cooked lentils. For eggs, you’d need about five large eggs — that’s a big omelette.

Plant-Based vs. Animal-Based Sources

Animal sources (meat, dairy, eggs) are generally more protein-dense per serving and contain all essential amino acids. Plant sources (lentils, quinoa, soy) can also provide 30g, but you’ll need larger portions and may need to combine different plants to get a complete amino acid profile.

What Are Some Surprising High-Protein Foods?

You might not think of vegetables or grains as protein powerhouses, but some pack a respectable punch.

Unexpected Protein Sources

• Peas: 1 cup cooked – 8g
• Spinach: 1 cup cooked – 5g
• Broccoli: 1 cup cooked – 4g
• Quinoa: 1 cup cooked – 8g
• Hemp seeds: 3 tablespoons – 10g
• Chia seeds: 2 tablespoons – 5g

Protein-Rich Vegetables and Grains

These foods won’t replace chicken or eggs as your main protein source, but they add valuable grams and come with fiber, vitamins, and minerals. For example, a cup of cooked spinach provides more protein per calorie than a steak — though you’d need to eat a whole bag to get the same total grams.

Nutritional Comparison

Per 100 calories, spinach delivers about 12g of protein, while eggs give about 8.5g. But because eggs are more calorie-dense, you get more total protein per bite. The trade-off: plants come with carbs and fiber, which can be an advantage or a disadvantage depending on your diet goals.
