Boiled Eggs: Calories, Protein and Nutrition
A simple guide to the calories, protein, fats, carbohydrates, vitamins and minerals in boiled eggs.
Boiled eggs are a convenient and nutrient-dense food that can provide high-quality protein along with important vitamins and minerals. Because boiling does not require added cooking oil, a plain boiled egg can be a relatively simple way to include protein in a balanced meal.
How Many Calories Are in a Boiled Egg?
A large hard-boiled egg, with an edible portion of about 50 grams, contains approximately 78 calories. It provides about 6.3 grams of protein, 5.3 grams of fat and 0.6 grams of carbohydrates. These values can vary somewhat according to egg size and preparation.

How Much Protein Is in a Boiled Egg?
Protein is one of the main nutritional features of eggs. One large hard-boiled egg supplies approximately 6.3 grams of protein. Egg protein contains all of the essential amino acids needed by the body, making whole eggs a useful protein-containing food.
Two large boiled eggs provide roughly 12.6 grams of protein and about 155 calories, while three provide approximately 18.9 grams of protein and 233 calories. :contentReference[oaicite:1]{index=1}
Boiled Egg Calories by Quantity
| Number of Eggs | Approx. Calories | Approx. Protein | Approx. Fat |
|---|---|---|---|
| 1 large egg | 78 kcal | 6.3 g | 5.3 g |
| 2 large eggs | 155 kcal | 12.6 g | 10.6 g |
| 3 large eggs | 233 kcal | 18.9 g | 15.9 g |
| 4 large eggs | 310 kcal | 25.2 g | 21.2 g |
Boiled Eggs and Fat
A large hard-boiled egg contains approximately 5.3 grams of total fat. Much of the egg’s fat is found in the yolk. The amount of fat makes a whole egg more energy-dense than egg white alone, while the yolk also contributes several important micronutrients.
Boiled Eggs and Carbohydrates
Eggs are naturally very low in carbohydrates. A large hard-boiled egg contains only around 0.6 grams of carbohydrate and no dietary fiber. Therefore, boiled eggs can fit into many eating patterns that emphasize relatively low-carbohydrate foods.
Vitamins and Minerals in Boiled Eggs
Calories and protein are only part of an egg’s nutritional profile. Whole boiled eggs also provide several micronutrients, with many of these nutrients concentrated in the yolk.
- Choline: An important nutrient involved in normal cell function and nervous-system processes.
- Vitamin B12: Helps support normal red blood cell formation and neurological function.
- Riboflavin (Vitamin B2): Involved in energy metabolism and normal cellular function.
- Vitamin D: Eggs provide a dietary source of vitamin D, although the amount can vary.
- Vitamin A: Supports normal vision, immune function and other physiological processes.
- Selenium: An essential mineral involved in antioxidant and thyroid-related functions.
- Iron: Eggs provide a modest amount of iron.
- Phosphorus: Important for bones, teeth and energy metabolism.
Egg White vs. Egg Yolk
The egg white contains a substantial portion of the egg’s protein and is very low in fat. The yolk contains protein as well, but it also provides most of the egg’s fat and many of its vitamins and minerals. Eating the whole egg therefore provides a broader range of nutrients than eating the white alone.
Whole Egg or Egg White?
If the goal is maximum protein with fewer calories and less fat, egg whites can be useful. If the goal is a broader nutritional profile, the whole boiled egg provides protein together with nutrients found in the yolk.
Are Boiled Eggs a Healthy Food?
Boiled eggs can be part of a balanced diet because they provide protein and several micronutrients in a relatively small serving. Their nutritional value also depends on what they are eaten with. Pairing eggs with vegetables, whole grains, legumes or fruit can create a more varied and nutrient-rich meal.
A boiled egg is also different nutritionally from an egg prepared with substantial amounts of butter or cooking oil because boiling itself does not add cooking fat.
Boiled Eggs for Breakfast
Boiled eggs can be an easy breakfast ingredient because they can be prepared in advance and combined with other foods. For example, a breakfast could include boiled eggs with vegetables, whole-grain toast and fruit.
The protein in eggs can contribute to a satisfying meal, while vegetables and whole grains can add fiber and other nutrients.
Boiled Eggs and Weight Management
At about 78 calories per large egg, boiled eggs can provide a relatively substantial amount of protein for their calorie content. However, weight management depends on overall calorie intake, physical activity, food choices and individual circumstances rather than one particular food.
Frequently Asked Questions

Are boiled eggs high in carbohydrates?
No. A large hard-boiled egg contains only about 0.6 grams of carbohydrate.
Does boiling add calories to an egg?
Boiling in water does not add cooking oil or butter. Nutrition databases may show slightly different values for raw and cooked eggs because water content and the reference serving weight can change during cooking.
Are egg whites lower in calories than whole eggs?
Yes. Egg whites contain most of the egg’s protein while containing substantially less fat and fewer calories than the whole egg.
Conclusion
Boiled eggs are a compact source of protein and several important nutrients. A typical large hard-boiled egg provides around 78 calories, 6.3 grams of protein, 5.3 grams of fat and less than 1 gram of carbohydrate. :contentReference[oaicite:2]{index=2}
