One large egg white contains about 17 calories, making it a low-calorie, high-protein food choice.
Breaking Down the Calories in an Egg White
Egg whites are often praised for their nutritional value, especially among those seeking lean protein sources. But exactly how many calories is 1 egg white? The answer is straightforward: a single large egg white contains approximately 17 calories. This makes it an excellent option for anyone watching their calorie intake but still wanting to get a solid dose of protein.
The calorie count in egg whites comes almost entirely from protein, with negligible amounts of fat and carbohydrates. Unlike the yolk, which carries most of the fat and calories, the white is mainly water and albumin protein. This low-calorie profile is why egg whites are staples in many diets focused on weight loss, muscle building, or simply healthy eating.
What Makes Egg Whites So Low in Calories?
Egg whites consist of about 90% water and 10% protein. The absence of fat significantly reduces their calorie content compared to whole eggs. For perspective, a whole large egg has roughly 70 calories, with the yolk contributing around 55 of those.
Because fat contains more than twice the calories per gram than protein or carbohydrates (9 vs. 4 calories per gram), removing the yolk slashes the calorie count dramatically. This makes egg whites a favored ingredient in recipes where reducing fat and calories is crucial without sacrificing protein.
Nutritional Composition of Egg Whites
Egg whites pack a powerful nutritional punch despite their low calorie content. They provide high-quality protein that contains all nine essential amino acids necessary for muscle repair and overall body function.
Here’s a detailed look at what you get from one large egg white:
| Nutrient | Amount per Large Egg White | % Daily Value* |
|---|---|---|
| Calories | 17 kcal | 1% |
| Protein | 3.6 grams | 7% |
| Total Fat | 0 grams | 0% |
| Carbohydrates | 0.2 grams | 0% |
| Sodium | 55 mg | 2% |
| Potassium | 54 mg | 2% |
*Percent Daily Values are based on a 2,000 calorie diet.
The data clearly shows that egg whites are nearly fat-free and carb-free while delivering a significant amount of protein with very few calories. This combination makes them ideal for anyone aiming to build lean muscle or maintain weight without excess caloric intake.
The Role of Protein in Egg Whites
Protein is essential for repairing tissues, building muscles, and supporting immune function. The proteins found in egg whites include ovalbumin, ovotransferrin, ovomucoid, and lysozyme—each playing different roles in nutrition and food science.
Ovalbumin makes up about 54% of the total protein content and is highly digestible. This means your body can efficiently use the amino acids from egg whites to support muscle synthesis and other vital processes.
Comparing Calories: Egg White vs Whole Egg vs Other Protein Sources
Understanding how many calories is 1 egg white helps when comparing it to other common foods rich in protein or used as substitutes in meals.
| Food Item | Calories (per serving) | Protein (grams) | |||

Egg whites offer a unique combination: very low calories with moderate protein content in a compact package. Compared to chicken breast or tofu, they provide fewer calories per gram of protein but less overall volume per serving. This makes them perfect for snacks or recipes where you want to boost protein without adding bulk or fat. Plus, since they’re virtually free of fat and carbs, they fit neatly into keto or low-carb diets as well.
