How Many Calories Are In An Egg White? | Calorie Breakdown

If you grew up hearing that egg whites are the “healthy part,” you’re not alone. The clear stuff circling the bright yellow yolk looks like pure protein, and the yolk looks like pure fat. It’s an easy visual shortcut — and it leads most people to assume the white carries most of the egg’s heft.

The truth is the calorie math leans the other way. A large egg white clocks in at just 17 to 18 calories. The whole egg carries about 70 calories. The white is almost pure protein and water, leaving virtually all the fat and cholesterol in the yolk. This article breaks down the exact numbers, compares them to whole eggs, and helps you decide which option fits your goals.

The Exact Calorie Count In One Egg White

A single large egg white provides roughly 17 calories when cooked without added fat. If you’re measuring raw, the number rounds up to about 18 calories. The difference is small enough that most people treat them as interchangeable.

Why the tiny gap? A raw egg white contains a little more water weight that cooks off. More importantly, the size of the egg matters. A medium egg white might land closer to 15 calories, while a jumbo egg white can push past 20.

Two large egg whites, a common serving for a healthy breakfast, deliver about 34 calories total. That’s roughly the same calorie load as half a slice of bread, but with a much higher protein density.

Why The Yolk Question Sticks

The real reason people look up egg white calories is rarely about the white itself. It’s about whether keeping the yolk is worth the extra calories, fat, and cholesterol. Here is what changes when you leave the yolk out.

• Calorie difference: A whole large egg contains about 70 calories. The white accounts for roughly 18 of those, meaning the yolk carries about 52 calories. Swapping two whole eggs for two egg whites saves roughly 104 calories.
• Fat content: Egg whites contain less than 0.1 grams of fat. A whole egg contains about 5 grams of fat, all of which is in the yolk.
• Cholesterol: The yolk contains approximately 180 milligrams of dietary cholesterol. Egg whites have zero cholesterol, making them a go-to option for anyone tracking their dietary cholesterol intake.
• Protein distribution: The white holds about 3.6 grams of protein, while the yolk holds about 2.4 grams. You lose just over a third of the total protein when you discard the yolk.
• Satiety factor: Many people find that whole eggs keep them fuller longer, largely because the fat in the yolk slows digestion. Egg whites alone may digest faster, which could leave you hungry sooner.

The choice isn’t strictly “good versus bad.” It’s a trade-off between calorie density, fat content, and the micronutrients found exclusively in the yolk.

How Egg Whites Fit Into A Daily Calorie Budget

For someone aiming to increase protein without adding many calories, egg whites are hard to beat. Healthline’s breakdown of the 18 calories raw egg white shows it provides over 3.5 grams of protein, which works out to about 15 grams of protein per 100 calories.

That protein-to-calorie ratio is higher than most meats and dairy products. Chicken breast, for comparison, offers roughly 10 grams of protein per 100 calories. Egg whites deliver similar efficiency with almost zero preparation waste.

For context, if you rely on egg whites for a post-workout meal, a 1-cup serving of liquid egg whites (about 8 large egg whites) provides 126 calories and roughly 26 grams of protein.

Serving Size	Calories (approx)	Protein (approx)
1 large egg white (raw)	18	3.6 g
1 large egg white (cooked, no fat)	17	3.6 g
2 large egg whites (cooked)	34	7.2 g
3 large egg whites (cooked)	51	10.8 g
1 cup liquid egg whites (raw)	126	26 g

These numbers assume no added oil, butter, or cooking spray. The moment you grease the pan, the calorie count shifts.

What You Lose When You Skip The Yolk

Cutting calories usually means cutting something else, too. When you remove the yolk, you lose more than fat and cholesterol. Here are the key nutrients that stay behind.

1. Fat-soluble vitamins: The yolk contains nearly all of the egg’s vitamin A, vitamin D, vitamin E, and vitamin K. Egg whites supply none of these.
2. Choline: The yolk is a significant source of choline, a nutrient important for brain health and cell membrane function. Egg whites contain almost no choline.
3. Iron and zinc: While egg whites provide small amounts of minerals like potassium and magnesium, the yolk holds the majority of the egg’s iron and zinc.
4. Omega-3 fatty acids: If the hens were fed an omega-3-enriched diet, those beneficial fats accumulate in the yolk, not the white.
5. Taste and texture: This isn’t a nutrient, but it matters. The yolk adds richness, moisture, and flavor that pure egg whites simply can’t replicate in recipes.

For some people, losing these nutrients is a worthwhile trade-off for a lower calorie count. For others, eating the whole egg provides a more balanced nutritional profile per calorie.

Practical Tips For Cooking Egg Whites

Cooking egg whites without adding fat is the easiest way to keep them low-calorie. Poaching, boiling, or using a non-stick pan with minimal spray keeps the final count at that baseline 17 to 18 calories per white.

Verywell Health offers a detailed egg white vs whole egg comparison that highlights the fat difference. The article notes that the moment you scramble whites in butter or oil, the calorie gap between whites and whole eggs shrinks dramatically.

If you’re using liquid egg whites from a carton, check the label. Most brands add natural flavorings or stabilizers, but the calorie count usually stays very close to fresh egg whites.

Cooking Method	Added Fat?	Approx Calories (per large white)
Poached / Boiled	No	17
Scrambled (non-stick spray)	Minimal	18–20
Scrambled (1 tsp butter)	Yes	40–50
Fried (1 tsp oil)	Yes	45–55

The Bottom Line

A large egg white contains about 17 to 18 calories, making it one of the leanest natural protein sources available. It’s a strong option for anyone cutting calories, monitoring cholesterol, or looking for a quick protein boost without much fat.
