A large boiled egg contains about 72 calories. That’s true whether it’s hard-boiled or soft-boiled, since the cooking time doesn’t change the calorie content. Most of those calories come from the yolk, which packs roughly 55 calories on its own, while the egg white contributes only about 17.
Full Nutritional Breakdown
Beyond calories, a large boiled egg delivers a surprisingly dense nutritional package for its size. You get about 6.3 grams of protein, 5.3 grams of fat (of which 1.6 grams is saturated), and just over half a gram of carbohydrates. That high protein-to-calorie ratio is one reason eggs show up so often in weight loss plans.
A single large egg also contains about 186 milligrams of cholesterol, nearly all of it in the yolk. That number used to scare people away from eggs, but the American Heart Association now considers one egg a day a reasonable part of a healthy diet for most people.
Eggs are also one of the best dietary sources of choline, a nutrient most people don’t get enough of. One large egg provides around 147 milligrams. Choline supports brain function and liver health, and the recommended daily intake is 550 milligrams for men and 425 milligrams for women, so a single egg covers roughly a third of that target.
Where the Calories Actually Come From
If you eat only the egg white, you’re looking at about 17 calories and almost zero fat (less than 0.08 grams). The white is nearly pure protein. The yolk, at 55 calories, carries almost all of the egg’s fat (4.9 grams) along with most of its vitamins and minerals. Removing the yolk cuts the calories in half but also strips out the choline, most of the B vitamins, and the fat-soluble vitamins like D and A.
For people counting calories strictly, two egg whites give you about 34 calories and 7 grams of protein. But if you’re eating eggs for their overall nutritional value rather than just minimizing calories, the whole egg is the better choice.
Hard-Boiled vs. Soft-Boiled
There’s no meaningful difference in calories or nutrients between hard-boiled and soft-boiled eggs. The only variable is cooking time. A soft-boiled egg (6 to 7 minutes) has a runny yolk, while a hard-boiled egg (10 to 12 minutes) is solid throughout. The longer cook time doesn’t destroy enough nutrients to show up in standard nutrition testing. The one practical difference: hard-boiled eggs are safer from a food safety standpoint, since the higher internal temperature is more effective at killing bacteria like salmonella.
Why Eggs Keep You Full
Eggs score 150% on the satiety index, a research scale that measures how full a food keeps you compared to white bread (set at 100%). That means eggs are 50% more filling than an equal-calorie serving of white bread. For context, croissants score just 47%, cake scores 65%, and white rice comes in at 138%. Protein content is one of the strongest predictors of how satisfying a food feels, and eggs are one of the most protein-dense foods per calorie.
In the same research, people who ate higher-satiety foods consumed fewer calories at their next meal. So a two-egg breakfast at roughly 144 calories may reduce what you eat later in the day more effectively than a 144-calorie portion of cereal or toast.
Calorie Counts by Quantity
- 1 large boiled egg: ~72 calories, 6.3g protein
- 2 large boiled eggs: ~144 calories, 12.6g protein
- 3 large boiled eggs: ~216 calories, 18.9g protein
- 1 egg white only: ~17 calories, 3.6g protein
These numbers are for large eggs, which weigh about 50 grams each. Medium eggs run closer to 63 calories, and jumbo eggs can reach 90. If you buy eggs at a farmer’s market where sizes vary, the weight printed on standard cartons is your best reference point.
How Cooking Method Changes the Count
Boiling is one of the lowest-calorie ways to cook an egg because you’re not adding any fat. A fried egg cooked in a tablespoon of butter jumps to about 120 calories. Scrambled eggs made with milk and butter can reach 90 to 100 calories per egg depending on what you add. Poached eggs, like boiled eggs, use no added fat and stay right around 72 calories.
If you’re tracking calories closely, boiled eggs have another advantage: consistency. A fried egg’s calorie count depends on how much oil or butter you use, which is hard to measure precisely. With a boiled egg, the number is always the same.
